VKO1 - User Manual

Overview

What is VKO1?

VKO1 is a professional visual performance app for Android. It plays your video clips, GIFs, images, and 3D models in sync with music. Designed for live performance, VKO1 delivers automated visual playback with precise BPM synchronization, 53 real-time effects, performance tape recording, and hardware controller support.

The Philosophy: Load your content, configure your performance, and let the app handle visual playback while you focus on your music.

8 Banks × 16 Pads

128 pads organized across banks A–H. Media added via MediaMesh3D nodes in the Node Editor — supports MP4, GIF, PNG, JPG, and OBJ.

BPM-Synced Playback

Tap tempo, manual entry, MIDI clock, Ableton Link, or real-time beat detection. Clips and effects animate on the beat.

53 Master Effects

GPU shaders (GLSL/Vulkan) for real-time processing. All BPM-synced with wet/dry control and custom color support.

Set It & Forget It

MIX auto-plays from all banks and rotates effects. MIX2 adds two-layer compositing with blend mode cycling. BLEND does the same compositing without touching your effects — fully hands-free.

Node Editor

Build custom reactive visuals with a visual graph editor. Wire generators, modifiers, and combiners together. React to BPM, audio energy, MIDI CC, and more. Full docs →

Store

Browse and download free and premium visual graphs from the built-in Store. Tap the bag icon in the top bar to open it. Drop any graph straight into your set.

Supported Devices: Android 12+ (API 31+)

Getting Started

Up and running

Load Content

Long-press any pad → Edit Graph. In the Node Editor tap + → Generators → MediaMesh3D. Then in the Inspector tap ADD IMAGE, ADD GIF, or ADD VIDEO to pick from your device. For OBJ models tap IMPORT OBJ.

Choose Mesh & Shape

In the MediaMesh3D inspector pick a mesh shape: Plane (flat screen-fill), Cube, Torus, Icosphere, Sphere, or Model (imported OBJ). The media plays on the chosen mesh.

Set Your Tempo

Tap the BPM display. Use tap tempo, manual entry, MIDI clock, or enable beat detection.

Add Effects & Auto-Play

Twist the Master Effect knob and pick an effect. Tap AUTO to cycle modes: SEQ, RND, SHF, MIX, MIX2, or BLEND for automated playback.

Adding a Visualizer

No media files needed — VKO1 includes 25 GPU-rendered visualizer types. Long-press an empty pad and tap "Add Visualizer" to browse types, pick a palette, and set reactivity. Visualizers respond to your audio, work with all effects and blend modes, and are included in Auto-Play rotation. See the Visualizers section for full details.

Note: On Android all media (video, GIF, image, OBJ) is loaded through a MediaMesh3D node in the Node Editor — not via folder import. Media files are copied into app-private storage on pick, so they are available offline.

Playback

Playing clips

Manual Mode

Tap any pad to play its clip. Tap another pad to switch.

Hold Mode

Tap HOLD to enable. Now tapping a pad toggles it on/off. Stack multiple clips as layers. Tap a playing pad again to remove it. Press CLEAR (or Escape) to release all.

Auto-Play Modes

Tap AUTO to cycle through modes:

SEQ

Sequential order within current bank (1, 2, 3, 4...)

RND

Smart random — avoids recently played clips

SHF

Pure shuffle within current bank

MIX

Auto-mix across all 8 banks with automatic effect changes. Prefers clips from different banks for maximum variety.

MIX2

Two-layer compositing mode. Keeps the previous clip as a base layer while bringing in a new clip on top. Automatically cycles blend modes on the upper layer at each trigger and rotates master effects. Prefers clips from different banks for variety. No HOLD required — the two-layer stack is managed automatically. When HOLD is active, held pads act as the fixed base and MIX2 cycles on top.

BLEND

Two-layer compositing mode — identical to MIX2 in how it stacks clips and cycles blend modes, but with one key difference: no master effect automation. Your effects stay exactly as you've set them. Every trigger brings a new clip on top of the previous base, and blend modes on the upper layer cycle automatically. Selects across all 8 banks. When HOLD is active, held pads act as the fixed base. Use BLEND when you want the evolving composite texture of MIX2 but need full control over your effects.

MIX2 & BLEND Settings: Open BPM Settings and scroll to AutoMix Options. Toggle Master Effect Automation (MIX2 only — BLEND never touches effects) and Blend Mode Automation independently. Blend mode automation fires at 40% probability per trigger and is skipped automatically under performance stress.

Time Division: Controls how often clips switch (1/16, 1/8, 1/4, 1/2, 1 bar, 2 bars, 3 bars, 4 bars). Adjust with DIV.

How to use: Long-press the MFX knob to open the picker. Tap an effect to assign it. Use < > arrows to cycle. Drag the knob vertically to adjust intensity. Long-press any effect in the picker for color settings, BPM division, favorites, and AutoMix exclusion.

Color & Grading — 9 effects

Invert

Flips every pixel to its RGB complement — blacks become white, colors rotate to their opposite on the wheel. At partial intensity, blends between original and inverted image.

Color Shift

Rotates the hue of all pixels through the color spectrum. Intensity controls rotation speed; at BPM sync the full hue wheel cycles once per beat division.

Saturation

Boosts or crushes color saturation. Below 50% intensity moves toward grayscale; above 50% pushes toward hyper-vivid neon. Pulses rhythmically at BPM.

Brightness

Raises or lowers the overall luminance of the frame. Low values darken toward black; high values blow out to white. Use at low intensity for a subtle exposure pump.

Contrast

Expands or compresses the tonal range. High contrast crushes blacks and blows out highlights for a punchy, graphic look that pulses on the beat.

Posterize

Reduces the number of distinct color levels, creating flat poster-art bands of solid color. Intensity controls the step count from many gradients down to two harsh tones.

Bloom

Simulates lens glow by spreading bright areas outward. Lights and highlights radiate a soft halo. Works especially well on neon and backlit footage.

Thermal

Maps pixel luminance to a false-color heat palette (blue → green → yellow → red). Converts any footage to an infrared camera aesthetic.

Gradient Map color

Replaces luminance with a synthwave gradient ramp (deep purple → cyan). Dark areas map to cool colors, bright areas to warm highlights. Open the color picker in the effect menu to customize the ramp endpoints.

Distortion — 9 effects

Pixelate

Chunks pixels into large blocks. Intensity controls block size from subtle lo-fi grain to coarse Minecraft-style squares. BPM sync pulses the block size on the beat.

Glitch

Simulates digital signal corruption: random horizontal slice offsets, RGB channel smearing, and noise bands. Looks like a dying VHS or corrupted video stream. Severity follows intensity.

RGB Split

Separates the red, green, and blue channels and offsets them horizontally in opposite directions. Creates the classic chromatic aberration prism-split look found in lo-fi and glitch aesthetics.

Displace

Uses an animated noise field to push pixels away from their original position. Creates a watery, displacement-mapped wobble. Intensity controls the displacement radius.

Datamosh

Simulates compression artifact glitches by smearing motion across the frame, as if I-frames were dropped from a video stream. Content bleeds and streaks with movement.

Wave Warp

Applies a sine-wave distortion horizontally and vertically. Intensity controls wave amplitude. With BPM sync, the waves ripple rhythmically on each beat for a pumping wobble.

Ripple

Radiates concentric sine-wave rings outward from the frame center, creating a pond-ripple displacement effect. Wave frequency and amplitude are BPM-synced; intensity controls displacement strength.

Pixel Sort

Sorts pixel columns by brightness within a luminance threshold, producing directional streaks of organized pixels. A signature glitch art technique that creates aurora-like vertical smears.

Sharpen

Amplifies high-frequency edges using an unsharp mask. Moderate intensity crisps footage; high intensity creates an over-sharpened, artificial digital artifact look.

Kaleidoscope & Mirrors — 6 effects

Kaleidoscope

2-fold radial symmetry. Mirrors the source quadrant twice and rotates the segments around a center point. Creates a shifting mandala from any footage.

Kaleido 4

4-fold symmetry. A more intricate mandala pattern formed from four mirrored and rotated copies of the source quadrant. Ideal for symmetrical, graphic content.

Kaleido 6

6-fold symmetry. Produces a hexagonal snowflake structure. The six segments rotate in sync with BPM for a spinning kaleidoscope effect.

Kaleido 8

8-fold symmetry for maximum kaleidoscopic complexity. Works especially well on footage that already contains repeating patterns or high contrast geometry.

Mirror

Flips the left half of the frame onto the right (bilateral symmetry). Simple and effective — any footage with strong asymmetry becomes suddenly surreal.

Mirror Quad

Mirrors both horizontally and vertically simultaneously, creating four-way symmetry from a single source quadrant. More geometric and abstract than bilateral mirror.

Blur — 2 effects

Blur

Gaussian blur softens all detail by spreading each pixel across its neighbors. Intensity controls the blur radius. Use at low intensity for a dreamy soft look, high intensity for total abstraction.

DOF

Depth of field simulation. Blurs the edges of the frame with a radial falloff while keeping the center sharp, mimicking a shallow-focus cinema lens. Intensity controls the vignette radius.

Feedback & Trails — 5 effects

Feedback

Feeds the output back into the input with each frame, creating growing geometric trails and tunnel-vision spirals. Iconic video synthesizer effect. Low intensity adds subtle trails; high intensity creates infinite recursive tunnels.

Echo Trails

Blends the current frame with a decayed copy of previous frames. Fast-moving content leaves comet-tail streaks. Intensity controls trail length and decay speed.

Ghosting

Overlays semi-transparent echoes of recent frames. Similar to Echo Trails but with opacity-based blending rather than additive. Great for slow panning footage and dreamy overlaps.

Strobe

Alternates between the live image and a frozen black frame on the beat division. Creates a strobe-light effect locked to your BPM. Use responsibly — avoid at high BPM in public venues.

Freeze

Locks a still frame of the current video output in place. With BPM sync enabled, creates a rhythmic freeze-release stutter: the image momentarily freezes on each beat, then snaps back to live playback.

Transform — 5 effects

Rotate

Continuously spins the entire frame around its center. Rotation speed is BPM-synced — one full revolution per beat division cycle. Intensity blends between stationary and fully rotating.

Scale

Rhythmically zooms in and out, creating a breathing, pumping effect. The zoom pulses on the beat. Intensity controls zoom depth from subtle push to aggressive slam-zoom.

Pinch

Applies an inward pinch warp radiating from the center, as if the image is being sucked into a lens. The warp pulses with BPM for a rhythmic vortex pull effect.

Spotlight

Fades the edges of the frame to black while preserving a circular center spotlight. Intensity controls spotlight radius, narrowing focus to a single bright point at full intensity.

Tile

Tiles the frame into a grid of smaller identical repetitions. Intensity controls the tile count — from 2×2 to a dense matrix. Creates a hypnotic mosaic of synchronized video tiles.

Psychedelic — 7 effects

Fractal

Overlays an additive fractal noise texture onto the image. The noise pattern animates and evolves in real time, synced to BPM. Creates organic, ever-changing grain that complements any footage.

Perlin

Similar to Fractal but uses smooth Perlin noise, producing cloud-like wisps and fluid organic structures. Softer and more flowing than the fractal variant.

Plasma

Generates classic 90s-era plasma waves in vivid neon colors blended onto the image. Multiple sine-wave interference patterns cycle through hues synchronized with BPM.

Liquid

Applies complex multi-frequency warping to make the image appear to melt and flow. More extreme and chaotic than Wave Warp, with each layer of warp moving at different rates.

Vorticella

Generates animated vortex and spiral patterns overlaid on the image. Named after the spiral-stalked protozoa. The spiral arms spin at a rate locked to BPM division.

Solarize

Inverts pixels above a luminance threshold, creating a partially-inverted photograph effect (Sabatier effect). With BPM sync, the threshold sweeps across the tonal range rhythmically, creating pulsing inversions.

Slit Scan

Samples a thin horizontal slice of the frame over time and composites the slices into a single image — the technique behind Star Trek warp tunnels and time-warp photography. Motion through the frame creates flowing smear patterns.

Vintage & Retro — 3 effects

Sepia color

Desaturates the image and applies a warm amber-brown tint. The color picker lets you replace the default sepia tone with any custom tint. Intensity blends from original to full toned effect.

B&W color

Converts to grayscale. The color picker lets you tint the bright areas any color (cyan, magenta, amber, etc.) while dark areas remain black — creating a duotone effect at partial intensity.

VHS

Simulates VHS tape degradation: horizontal scan lines, color bleed at high-contrast edges, noise bands drifting vertically, and slight desaturation. Intensity controls artifact severity from subtle Lo-Fi to completely degraded.

Stylize — 7 effects

Halftone color

Renders the image as a grid of circles whose size is proportional to pixel brightness, like a newspaper print screen. Background color between dots is user-selectable. Intensity controls dot scale and spacing.

Edges color

Edge detection shader that isolates luminance boundaries and draws them as bright lines on a dark background — a neon wireframe of your footage. Line color is user-selectable. Great with high-contrast geometric content.

ASCII

Converts the image to block text characters (█ ▓ ▒ ░) scaled to pixel brightness, creating a real-time ASCII art rendition of your footage. Character density follows intensity.

Oil Paint

Applies a Kuwahara filter that groups neighboring pixels into smooth brush-stroke-like patches, giving footage the appearance of a painterly oil painting. Intensity controls brush size and abstraction level.

Rutt-Etra color

Emulates the Rutt/Etra analog video synthesizer from the 1970s: displaces horizontal scan lines vertically based on pixel brightness, forming a 3D wireframe topology. Default line color is phosphor green — user-selectable.

Glass

Applies a frosted glass refraction using a noise-based displacement map, making the image appear to be seen through textured or bumped glass. Works well combined with Blur at low intensity.

Outline color

Draws a soft Blender-style edge glow around bright regions of the frame. Tint color is user-selectable; edge width and glow intensity react to the beat.

Per-Clip Pad FX

Long-press a pad and select "Effects" to apply effects to individual clips. Per-clip effects are applied before the master effect, so they stack multiplicatively.

Favorites

Long-press any effect in the picker and choose "Add to Favorites". Favorites appear in a dedicated star tab for quick access during performance. Favorite status persists across sessions.

Exclude from AutoMix

Long-press any effect in the picker and select "Exclude from AutoMix". MIX mode will skip excluded effects during automatic effect rotation, but they remain available for manual use.

Custom Effect Colors

Six effects support a user-chosen color, opened via the color palette icon in the effect picker:

Halftone — background fill between dots Sepia — tint color B&W — highlight tint Edges — line color Rutt-Etra — scan line color Gradient Map — ramp color

Generative Visuals

Built-in Visualizers

Twenty-five GPU-rendered visualizer types that run directly on the pad grid. No video files needed — everything is generated in real time via GLSL shaders. Visualizers react to your audio, work with all master and per-pad effects, blend modes, and save with your sessions.

Adding a Visualizer

There are two ways to place a visualizer on a pad:

Empty pad

Long-press an empty pad and tap "Add Visualizer". This opens the Visualizer Picker where you can browse types, choose a palette, and adjust settings with a live preview before assigning.

Replace existing clip

Long-press a pad that already has content and open the "Replace with Visualizer" submenu. Pick a visualizer type and it replaces the current clip immediately.

Visualizer Picker

Full configuration sheet with live preview, type grid, horizontal scrolling palette picker, and sliders for reactivity and complexity. Tap "Assign to Pad" when ready.

Tweaking After Assignment

Long-press any visualizer pad to open its context menu. From there you can change:

Type	Switch between all 25 visualizer types without removing the pad
Palette	Pick from 33 color palettes
Reactivity	How strongly the visualizer responds to audio (Low / Medium / High / Max)
Complexity	Detail level from minimal to maximum (affects layer count, particle density, etc.)

Visualizer Types

25 types — all GPU-rendered

Plasma

Classic plasma waves generated by overlapping sine functions. Produces flowing, organic color gradients that shift and morph continuously. Complexity adds more sine layers for denser interference patterns.

Voronoi Cells

Animated Voronoi diagram with drifting cell centers. Creates an organic, cellular texture that resembles stained glass, reptile scales, or microscope imagery. Complexity controls the number of cell points.

Fractal Noise

Multi-octave fractal Brownian motion (fBm) noise field. Produces cloud-like, terrain-like structures that evolve slowly over time. Complexity adds more octaves for finer detail. Audio energy drives the noise evolution speed.

Tunnel Warp

An infinite tunnel effect using polar coordinate warping. The camera appears to fly through a textured tunnel whose walls twist and pulse. Beat strength controls tunnel speed; complexity adjusts wall distortion layers.

Starfield

Multi-layer parallax starfield with twinkling, color variation, and a subtle nebula background. Deeper layers move faster for depth. Audio energy drives flight speed; beat hits flash all stars brighter. Complexity adds more parallax layers. 3 stars per grid cell for density.

Geometric Patterns

Concentric rings of segmented geometric shapes that rotate in alternating directions. Beat phase modulates the rotation. Complexity adds more rings. Creates mandalas and spirograph-like structures.

Spectrum Rings

Radial frequency bars arranged in a circle. Each bar reads live spectrum data and extends outward from the center, creating a radar/sonar-like display. Signal is heavily amplified for maximum visibility. Complexity controls the number of frequency bins displayed.

Particle Fountain

GPU-instanced particle system with thousands of particles that spawn, drift, and fade. Beat strength boosts spawn rate, velocity, and particle size. Particles use additive blending for a glowing, firefly-like appearance. Complexity controls the maximum number of active particles.

EQ Bars

Classic equalizer bar display driven by live spectrum data. Each bar represents a frequency bin and grows in real time. Aspect-ratio aware — bars grow vertically in portrait and horizontally in landscape. Complexity controls the number of bars (8–32). Defaults to maximum complexity.

Audio-reactive

Spectrum Wave

Smooth flowing waveform lines that fill the entire screen. Multiple wave layers are stacked vertically, each reading from a different offset in the spectrum data for organic variety. Every layer has its own palette hue, glow, and fill. Complexity controls layer count (4–16).

Audio-reactive

Oscilloscope

DAW-style oscilloscope that draws the audio waveform as a bright, glowing line across the screen. The waveform thickens and pulses with beat strength. A subtle phosphor afterglow trails behind the main trace. Complexity controls the line resolution and glow width.

Audio-reactive

Level Meter

LED-segment level meters like those on a hardware mixing console. Each channel averages a region of the spectrum and displays it as a column of lit LED segments. Aspect-ratio aware — meters grow vertically in portrait and horizontally in landscape. Complexity controls channel count (2–8) and segment resolution. Defaults to maximum complexity.

Audio-reactive

Grid Pulse

A sharp, animated grid of intersecting lines that drifts slowly across the canvas. Audio energy sends ripple waves outward from the center, distorting the grid in real time. Every line crossing flares brightly on beat hits, and a radial vignette keeps energy focused at the center. Complexity controls grid density.

Neon Prism

Concentric regular polygons — triangles, squares, pentagons, hexagons, heptagons, and octagons — stacked concentrically and rotating in alternating directions at staggered speeds. Each ring has a sharp neon-glowing edge with layered halos. Inner rings pulse dramatically on beat; outer rings hold steadier. Complexity controls how many rings are drawn (3–10).

Laser Web

Multiple ultra-thin laser lines radiate from the center of the canvas, each one rotating at a slightly different speed in alternating directions. The lines have a razor-sharp core with a narrow glow halo; where they overlap, additive blending creates naturally blazing intersections. Beat fires a central strobe flash. Complexity controls beam count (3–12).

Shard Burst

Triangular shards radiate from the center, each one driven by a live spectrum bin. Shard height maps directly to frequency energy — louder frequencies produce longer, more dramatic spikes. Each shard tapers to a sharp point with glowing angular edges and a bright tip halo. The entire arrangement rotates slowly with a snap on the beat. Complexity controls shard count (8–32).

Audio-reactive

Signal Decode

Industrial data stream with horizontal glitch scan lines and corruption blocks that snap to a grid on beat. Vertical data streams scroll downward, edge bracket markers frame the display, and corruption bands flash across on impact. Beat-quantized randomness keeps every hit surprising. Complexity controls grid density.

Marathon-inspired

Tactical Grid

HUD-style tactical radar display with concentric dashed range rings, crosshairs, and a rotating radar sweep. Targeting brackets jump to new random positions on each beat. Tick-mark coordinates line the edges. An expanding pulse ring radiates outward on every hit. Complexity controls target count and grid detail.

Marathon-inspired

Glyph Matrix

A grid of procedural geometric symbols — crosses, diamonds, triangles, circles, arrows, crosshairs, data bars, and dot patterns — that randomly shuffle and snap-rotate (0°/90°/180°/270°) on each beat. A wave-based reveal animation sweeps across the grid. Complexity controls grid size.

Marathon-inspired

Schematic Pulse

Circuit board traces with orthogonal lines, intersection nodes, diagonal connectors, and data packets that travel along the traces. Hub nodes with concentric rings flash on beat. Random nodes light up on each hit. Complexity controls trace density and hub frequency.

Marathon-inspired

Terminal

Old CRT terminal rapidly loading a program. Fast-scrolling fake code lines, memory addresses, progress bars, blinking cursor, and status readouts. Beat triggers glitch corruption rows and scroll speed bursts. CRT scan lines and phosphor vignette complete the retro feel. Complexity controls character density.

Retro

Tron Grid

Infinite perspective wireframe grid floor rushing toward the camera, with a matching sky grid receding above the horizon. Bright vector horizon line with glow, floating wireframe shapes (diamonds, squares, circles) rotating in space, and vertical accent lines. Classic 1982 vector monitor aesthetic. Beat pulses the grid in waves.

3D Vector

Wire Tunnel

Flying through a rotating wireframe tunnel with morphing polygon cross-sections that shift between triangles, squares, pentagons, and beyond. Longitudinal lines connect the rings. Beat spawns expanding flash rings and accelerates flight speed. A glowing vanishing point marks the tunnel core. Complexity controls ring count and polygon variation.

3D Vector

Vector Terrain

80s wireframe mountain landscape with noise-driven peaks scrolling toward the camera. A retro sliced sun sits on the horizon with twinkling vector stars above. Beat makes the terrain peaks spike dramatically. Vertical perspective grid lines add depth to the floor. Complexity controls mesh resolution.

3D Vector

Holo Cube

Up to 7 nested wireframe cubes rotating independently on all three axes with full perspective projection. Inner cubes spin faster. Glowing vertex dots mark the corners of the outermost cube. Beat triggers scale pulses and 90° axis snaps. Complexity controls nesting depth.

3D Vector

33 Color Palettes

Every visualizer type supports all 33 palettes. A random palette is assigned each time you load a new visualizer. Colors are generated procedurally using cosine-based gradient functions, so they produce smooth, continuous color ramps rather than hard steps.

Cyberpunk Neon Fire Ice Nature Synthwave Monochrome Rainbow Toxic Blood Moon Electric Lava UV Candy Matrix Inferno Mono Red Mono Blue Mono Green Mono Purple Mono Amber Mono Cyan Mono Pink Sunset Ocean Vapor Copper Aurora Coral Midnight Rust Hologram Marathon

Audio Reactivity

Visualizers respond to three audio signals from the beat detection engine:

Beat Strength	Impulse on each detected beat — triggers flashes, particle bursts, speed boosts
Energy	Overall audio loudness — drives continuous animation speed, brightness, particle velocity
Beat Phase	Position within the current beat cycle (0–1) — used for smooth oscillations and rotations

The Reactivity slider scales how much these signals affect the visualizer. At zero, the visualizer animates on its own clock. At maximum, every visual parameter is driven by the audio. Reactivity defaults to maximum for all visualizer types.

Works Like Any Clip

Once assigned to a pad, a visualizer behaves exactly like a video clip:

Master Effects	All 53 effects apply to visualizers (kaleidoscope, glitch, feedback, etc.)
Per-Pad Effects	Long-press the pad to assign a per-clip effect that stacks with the master
Blend Modes	Additive, multiply, screen, difference — layer visualizers with video clips
Opacity	Adjust per-pad opacity for layering
AutoMix	Visualizer pads are included in MIX, SEQ, RND, and SHF rotation
Sessions	Full visualizer config (type, palette, reactivity, complexity) saves and restores with sessions and performance scenes

Tip: Layer a visualizer pad with a video clip using additive blend mode for an instant reactive overlay. Set the visualizer to high reactivity and the video to a loop — the visualizer pulses on top of your footage.

Generative Visuals

Node Editor

The Node Editor lets you build custom reactive visuals by connecting nodes on a graph canvas — no coding required. Each node is a processing block: generators create visuals from scratch, modifiers transform them, combiners blend layers together, and inputs feed live data like BPM, audio energy, or MIDI into the graph.

Access it from the pad context menu (Long-press pad → Edit Graph) or via the node editor button in the toolbar. Tap + to open the node palette and add nodes. Connect output ports to input ports by dragging. The result renders in real time on the pad.

Generators

Create the base visual layer. Includes all 25 built-in visualizer types, MediaMesh3D (video/GIF/image/OBJ on a 3D mesh), and custom GLSL shaders. Each generator has its own palette, complexity, and reactivity controls.

Modifiers

Transform a layer — color controls, affine transform (rotate, scale, translate), twirl, vortex, blur, film look, and more. Chain multiple modifiers for compound effects.

Combiners

Blend two layers together using standard blend modes (add, multiply, screen, overlay, difference…). Mix parameter controls the blend ratio between the two inputs.

Inputs

Feed live data into graph parameters. Constant, LFO (sine, square, saw, triangle), MIDI CC (reads a live CC value 0–127), and MIDI Note (reads velocity of a specific note).

MediaMesh3D — Loading Video, GIF & Images

MediaMesh3D is the generator node for all media content on Android. Add it from the node palette, then use the Inspector to configure it:

Inspector control	What it does
ADD IMAGE	Pick a PNG / JPG from your device via the Android photo picker
ADD GIF	Pick a GIF — plays back BPM-synced or at native speed
ADD VIDEO	Pick an MP4 — loops on the pad, audio-reactive
IMPORT OBJ	Load a custom 3D mesh (only visible when Mesh = Model)
Mesh chips	Plane · Cube · Torus · Icosphere · Sphere · Model

Media is copied into app-private storage on pick and survives app restart. The node renders the media on the chosen mesh in the 3D environment, fully reacting to BPM and audio signals.

Custom GLSL Shaders

Tap New Shader from Scratch in the node palette to create a blank GLSL fragment shader. Edit the source directly in the built-in code editor — three modes available: Snippet (write one vec4 vko_main(vec2 uv) function), 3D (write vko_vertex and/or vko_fragment), or Full Shader (start with #version 450 for a complete GLSL file). Compiled shaders appear in the My Shaders library and can be placed on any graph. Import existing .glsl files via the import button in the node editor toolbar.

Saving & Sharing Graphs

Finished graphs are saved with your session. Tap the bookmark icon to save a graph to the Graph Library for reuse across sessions. Tap the share icon to export a .vkograph file — share via the Android share sheet or Files. Import graphs from the session manager or by opening a .vkograph file.

The vertical bar fills from the bottom. Color changes automatically as usage climbs:

Color	Usage	Meaning
Green	Below 35%	Plenty of headroom. Load freely.
Orange	35–55%	Getting full. Avoid adding many more heavy clips.
Red	Above 55%	High pressure. Android may terminate the app if usage keeps climbing.

Tap for details

Tapping the MEM chip opens a popover with a full breakdown:

App footprint — total physical RAM used by the process, in MB and as a proportion of device total.
Reverse frame cache — how much of that memory is used by pre-decoded video frames (reverse / ping-pong playback). Shows MB used and how many clips are cached.
Warning tip — appears at high usage with advice to reduce clip count or switch to forward-only playback modes.

What fills memory

Regular forward playback is streamed and uses minimal RAM. Memory usage climbs when:

Reverse or Ping-Pong playback mode is active on a clip — all frames must be decoded in advance and held in memory for smooth reverse scrubbing.
High-resolution source videos (1080p/4K) with many frames — each frame at 1080p uses ~8 MB. VKO1 caps each clip at 256 MB of decoded frames automatically.
Many clips loaded across all banks simultaneously.

Pro Tip: If you need reverse playback on long 1080p clips, trim them to the essential section first (long-press pad > Trim). Shorter clips decode fewer frames. Or switch to 720p exports for the same visual result at a quarter of the memory cost.

Tempo

BPM & Sync

Set Your BPM

Tap Tempo: Tap the BPM display, then tap the tempo button in rhythm (at least 4 taps).

Manual Entry: Tap BPM display > Manual Input > type BPM (20-300) > Set.

Sync Sources

Internal Clock

Manual BPM via tap tempo or direct entry. The default for standalone use.

MIDI Clock

Receive 24 PPQN clock from your DAW, drum machine, or hardware. Transport follows external play/stop.

Ableton Link

Sync tempo, beat, and phase over the local network with Ableton Live, Traktor, Serato, and other Link-enabled apps.

Audio Beat Detection

Real-time analysis detects tempo from audio. Genre presets constrain BPM range to prevent drift.

Beat Detection

Tap BPM display > enable "Audio Beat Detection". The app listens to your music and detects tempo in real-time. Auto-starts/stops playback when audio is present/absent.

Genre Presets

Constrain beat detection to the correct BPM range:

Genre	BPM Range
Any	60–200
Hip Hop	70–105
Reggaeton	88–104
House	118–135
Techno	125–155
D&B	160–190
Dubstep	135–150
Pop	95–135
Rock	100–145

Network Sync

Ableton Link

Ableton Link synchronizes tempo, beat, and phase across multiple devices and apps on the same local network. Every Link-enabled app shares one unified timeline — no master/slave, no cables, no configuration.

What is Ableton Link?

Link is a protocol by Ableton that keeps apps in sync over Wi-Fi. When enabled, all Link peers on the network agree on a shared tempo and beat grid. If one app changes tempo, all others follow instantly. VKO1 uses Link to sync visual playback with your music apps.

Compatible Apps

Ableton Live Traktor Serato DJ djay Reason Maschine Bitwig Studio Logic Pro Koala Sampler AUM Drambo

And hundreds more. Any app with Ableton Link support works with VKO1.

How to Enable

Tap the BPM display to open BPM & Sync settings
Under Sync Source, select "Ableton Link"
Or toggle the Ableton Link switch in the dedicated section below
A status indicator shows connection state:
- Green circle — Connected to peers
- Orange circle — Searching for peers on the network
Enable Link in your other apps (Ableton Live: Link button in top bar, Traktor: Preferences > Link)

How It Works

Shared Tempo

All peers agree on one BPM. Change tempo in VKO1 or any other Link app — everyone follows. No master device needed.

Beat & Phase Sync

VKO1 reads beat position and phase from the Link session. Clip switches and effect animations lock precisely to the shared beat grid.

Zero Config

No IP addresses, no pairing. All devices on the same Wi-Fi network discover each other automatically via multicast UDP.

Peer Count

The BPM settings screen shows how many Link peers are currently connected. The Link tempo display shows the shared session BPM.

Network Requirements

All devices must be on the same Wi-Fi network
The network must allow multicast/broadcast UDP traffic (most home and studio networks do)
Corporate or venue networks sometimes block multicast — use a portable router or hotspot if Link can't find peers
No internet connection required, just local network connectivity

Pro Tip: For rock-solid sync at a gig, bring a dedicated portable router. Connect your laptop and Android devices to the same network. Link works over any local network — even a phone hotspot.

Typical Setup

Laptop running Ableton Live / Traktor / Serato with Link enabled
Android device running VKO1 with Link enabled, outputting visuals via HDMI
Both on the same Wi-Fi — visuals automatically sync to the DJ’s tempo and beat grid

The DJ changes BPM in their software — VKO1 follows instantly. Clips switch and effects animate precisely on beat. No MIDI cables, no manual BPM entry, no drift.

Output

Send visuals anywhere

Tap the TV / monitor icon in the top bar to open the Output sheet. Three independent output paths are available simultaneously.

Screen Mirroring / Cast

Mirror your full screen wirelessly to any Chromecast or screen-cast receiver. Swipe down → Quick Settings → Screen Cast. Tap your device name. Full screen including all effects.

Clean Visual Output (HDMI)

Connect via USB-C adapter. Secondary screen shows only the rendered visuals — no pads, no controls. Your main screen keeps all controls.

RTMP Stream

Stream renderer-only output over your local network. No UI overlays — exactly what the Vulkan renderer produces. Works with OBS, Resolume Arena, VDMX, and any RTMP-capable software.

Screen Mirroring / Casting

Uses Android's built-in screen cast. Streams your full screen including all effects and visualizers to a Chromecast, smart TV, or compatible receiver.

Swipe down from the top of the screen to open Quick Settings
Tap Screen Cast (or Cast / Smart View on Samsung)
Select your display from the list

Note: Screen Cast mirrors the full screen including the VKO1 UI. If you want clean visuals only (no pads or controls on the output), use HDMI or RTMP instead.

Clean Visual Output — HDMI / USB-C

Plug in a USB-C to HDMI adapter. The Output sheet shows a green indicator when a secondary display is detected. The external screen renders the same Vulkan visuals with no UI elements at all — projector-ready, monitor-ready.

HDMI Status Indicators

Dimmed icon — No display connected
Red indicator — Adapter detected but clean output not started
Green indicator — Clean output active on external screen

Tap Refresh Connection in the Output sheet if the adapter was plugged in after the app started.

Frame Rate

The Output sheet includes a frame rate selector that applies to the external display:

Setting	Behavior
MAX	Requests the display's highest supported refresh rate (90 or 120 Hz on capable panels)
120 / 90 / 60 / 30	Caps the frame rate to the chosen value. Lower caps save battery and reduce heat.

RTMP Streaming

RTMP streams the renderer output — the exact same Vulkan-rendered frame — over your local network as an H.264 video stream. No UI overlays, no pads, no controls. What you see in the visualizer is what gets streamed.

What it streams

Only the Vulkan renderer output. All master effects, blend modes, and visualizers are included. The VKO1 interface (pads, knobs, controls) is never captured.

What you need

An RTMP server on your local network — OBS RTMP server, mediamtx, Nginx-RTMP, or any software that accepts RTMP input. Both devices on the same Wi-Fi.

Setting up the RTMP URL

In the Output sheet, enter an RTMP URL and tap START STREAM. The status dot shows:

Dot color	State
Grey	Off — not streaming
Orange	Connecting…
Green	Live
Red	Error — check URL and server

Tap STOP STREAM to end. The URL is saved automatically between sessions.

Stream orientation

The RTMP stream matches your phone's current orientation exactly — the same content the renderer produces, with no cropping or rotation applied. Portrait phone = 9:16 stream. Landscape phone = 16:9 stream. Rotate your device before starting the stream to get the aspect ratio you want in OBS or Resolume.

Testing with mediamtx (Mac)

mediamtx is a free RTMP server. Run it on your Mac to receive the stream from VKO1.

Install mediamtx:
brew install mediamtx
Create the required config file (mediamtx v1.18+ needs this to accept incoming streams):
echo "paths: all_others:" > ~/mediamtx.yml
Or create ~/mediamtx.yml with:
paths: all_others:
Start the server:
mediamtx
Listens on RTMP port 1935. To run as a background service: brew services start mediamtx
Find your Mac's local IP:
ipconfig getifaddr en0
In VKO1 Output sheet, enter:
rtmp://192.168.x.x:1935/live/vko1
Tap START STREAM. The dot turns green when connected.

Receiving in OBS (Mac or PC)

In OBS, add a source: + → Media Source
Uncheck Local File
Set Input to:
rtmp://localhost:1935/live/vko1 (if mediamtx is running on the same machine)
Click OK. The VKO1 renderer output appears as a source in OBS.

From OBS you can record to disk, add to a virtual camera, or re-stream to any platform (YouTube, Twitch, etc.).

Receiving in Resolume Arena

In the clip browser, right-click an empty slot → Add URL
Enter:
rtmp://localhost:1935/live/vko1
The VKO1 output appears as a live clip. Route it to any layer or output in Resolume.

Network tip: For stable streaming, make sure your Android device and receiving computer are on the same Wi-Fi network. Streaming over a 5 GHz band reduces latency. Avoid corporate or venue networks that block multicast — use a portable router or hotspot if needed.

Help

Troubleshooting

"No clips appear after import"

Check format: MP4, GIF, PNG, JPG, JPEG, OBJ
Try importing to a specific pad (long-press > Import)

"Auto-play doesn't start"

Make sure AUTO is enabled (shows SEQ/RND/SHF/MIX/MIX2/BLEND)
Check that clips are loaded and BPM is set
If using Beat Detection, make sure audio is present and transport is on Play

"MIX2 or BLEND blend modes are not changing"

Both modes require at least two clips to be active — the second layer builds automatically after the first trigger, so blend changes begin from the second clip switch onward
Check that Blend Mode Automation is enabled in BPM Settings > AutoMix Options
Blend mode changes fire at 40% probability per trigger — some beats will pass without a change by design
Changes are suppressed when the performance guard is at minimal level (thermal stress or low FPS)
In BLEND, master effects are never automated — if your effects are changing, you are in MIX2, not BLEND

"MIDI controller not detected"

Check USB/Bluetooth connection
Go to MIDI Settings and tap "Scan for Devices"
Some controllers need to be in "USB MIDI mode"

"App crashes or quits unexpectedly"

Watch the MEM gauge — if it is orange or red before the crash, memory pressure is the cause
Avoid loading very long high-resolution clips (1080p, 120+ seconds) in Reverse or Ping-Pong playback mode; trim them first
Switch heavy clips to Forward-only playback to avoid pre-decoding all frames
Close background apps to free system RAM before starting a performance

"Video playback is choppy"

Try lower resolution clips (720p is usually sufficient for projected output)
Close other apps
Reduce simultaneous effects

"External display shows UI elements"

Disable screen mirroring in Control Center. Use the built-in output feature via the TV icon.

Workflows

Common setups

DJ Set with Auto-Play

Import 8 folders (one per bank). Set BPM, enable Beat Detection, or use Ableton Link. Enable AUTO > MIX for fully automated visuals. Override manually anytime.

Hands-Free Layered Visuals (MIX2)

Load thematically grouped content into banks. Enable AUTO > MIX2. VKO1 keeps two clips layered and continuously remixes the blend mode — the look evolves without any intervention. Combine with master effects automation for a fully self-generating visual set.

Compositing with Effects Control (BLEND)

Dial in the exact master effects you want, then enable AUTO > BLEND. VKO1 keeps two clips layered and continuously cycles blend modes — but never changes your effects. Use this when you want evolving compositing textures while staying in control of the overall look and feel.

VJ + DJ with Ableton Link

DJ runs Traktor/Serato/Ableton with Link enabled. VJ runs VKO1 on Android with Link enabled, outputting via HDMI. Tempo and beat sync automatically — no cables, no drift.

Live Performance with MIDI

Connect controller, select preset. Tap pads on hardware. Use fader for dry/wet, +/- for effects. Record with Tape.

Loop Station Visuals

Start tape recording (REC). Perform a sequence. Stop — it loops. Overdub to layer more. Build up complex multi-layer performances.

Tips

Best practices

Performance

Use shorter clips (5-15 sec). GIFs loop seamlessly. Images are great for overlays. Trim clips to their best section.

Content Organization

Group by visual theme or energy level. 16 items per folder for 1:1 bank mapping. Mix content types.

MIDI Tips

EP-133: use the built-in preset. Launchpad/APC: grid mode. MIDI Learn is faster than manual mapping.

Auto-Play

1/16 = fast cuts, 1 bar = slow transitions. MIX respects "Exclude from AutoMix" effect settings. For MIX2 and BLEND, organize content so each bank has a consistent visual theme — same-bank pairing produces more coherent blend results. Choose BLEND over MIX2 when you've set specific master effects and don't want them touched during the set.
