The Pitch

NO VJ?
NO PROBLEM.

You're behind the decks. The crowd wants visuals. You don't have a VJ, a laptop rig, or a free hand.
VKO1 runs the visuals for you — tempo-matched, beat-locked, auto-cycling effects — on the phone already in your pocket.

⟡ Star Feature

AutoMix.
Set it & forget it.

Seven playback modes, from manual to fully autonomous. MIX is the flagship — all banks, auto-cycling effects, zero input. MIX2 layers two clips with cycling blend modes. BLEND focuses on the composite — you keep your effects, it keeps evolving.

OFF
Manual only. You trigger every clip.
02
SEQ

04
SHF

TIME DIV ↻
Control switching speed from rapid-fire 1/16th cuts to slow 1-bar transitions. Adjust on the fly with the DIV button — VKO1 stays locked to whatever you're playing.

VKO1 now speaks MCP — the open agent protocol. Connect Claude Code, Codex, Gemini, or any MCP client and it writes Metal shaders, builds node graphs, previews its own renders, and pushes visuals straight onto your pads. Live.

◉

It writes real shaders

Custom Metal fragments, node graphs, whole scenes — authored by the agent and pushed onto your pads without you touching the keyboard.

↻

It fixes its own code

Shaders compile inside VKO1. The agent reads the actual Metal compiler errors and iterates until the render works.

⚡

It performs

Trigger pads with HOLD layering, set BPM, switch AutoMix modes, ride both Master FX knobs, and read live energy + beat strength to move with the music.

⬢

Zero install, any agent
