A live performance environment where AI doesn't replace the musician — it plays alongside them. PULSE responds to live musical input in real time, generating harmonics, textures, and evolving melodic layers that adapt with every note. AI as instrument, not autopilot.
The question at the heart of PULSE: what if AI could be an instrument? Not a studio tool, not a post-production aid, but something a musician could actually perform with — live, in front of an audience, with real stakes. The brief was to build a performance environment that makes generative AI a genuine creative collaborator, not a gimmick.
Most AI music tools are designed for production workflows: generate a loop, export a stem, use it in your DAW. They assume latency, they assume editing, they assume a human review step before anything reaches the listener. Live performance removes all of those assumptions. The system needs to respond in milliseconds. It needs to stay musically coherent across the arc of a set. And it needs to give the performer control — not to manage the AI, but to play with it.
The other challenge was philosophical. Tools that do too much undermine the performer. PULSE had to be opinionated about where AI ends and the musician begins.
PULSE is built as a performance environment, not a production tool. It processes live audio input — from instruments, microphones, or DJ controllers — and uses that signal to inform generative AI output in real time. GPT-4o interprets the musical context: the key, the energy, the emotional register of what's being played. From that context, the system generates complementary elements — harmonics, counter-melodies, textural layers — that are fed back into the live mix.
Custom MIDI integration lets performers control the AI's contribution directly: how much it plays, what register it occupies, when it pulls back. The design principle was clear — the AI should make the musician sound better, not compete with them. When the performer pushes into a solo, PULSE recedes. When they hold a groove, it elaborates.
The Web Audio API handles real-time signal processing in the browser, keeping the system deployable without specialist hardware. Low-latency was a non-negotiable design constraint throughout.
A working prototype demonstrated in a live performance setting — verified in front of an audience, not just a dev environment. The response from performers was that PULSE felt like playing with a bandmate who happened to never miss a cue. Ongoing development is underway toward a wider release targeting experimental, electronic, and ambient artists who want to integrate generative AI into their live sets without surrendering creative control.
