MIDI In
Live MIDI input — pick a hardware controller from the dropdown to play a synth voice (the hardware counterpart to the on-screen Keyboard; wire BOTH into a voice in parallel and choose either). A NOTE controller (no sound of its own): it outputs Pitch + Gate, and audio.js turns each incoming MIDI note into the voice's frequency + an open gate — the SAME note→voice path as the Keyboard. Device ids are runtime I/O (audio.js owns requestMIDIAccess), never kernel state.
