HOW DO YOU
WANT TO PLAY?

Two sides of the same prism. Pick one to begin — you can swap anytime.

◑ LEARNER
Learn a song.
Falling notes and wait mode. Note names, finger numbers, loop a bar, slow to 40%. Built to take a song from zero to yours.

Plug in your MIDI keyboard and press a few keys — they should light up below. No keyboard? You can play on your computer's keys instead.

VOL
{{ volPct }}
In the full app you drag in any song ever made — and learn it.
These handful of demo songs are pre-charted. The real thing splits whatever you paste in, transcribes it to notes, and fits it to your keyboard in about twelve seconds.

Set the character, then generate. It writes an original piece over your progression — never the same twice.

Bank voices are on-device approximations of your Serum presets. For the originals, load the preset in Serum and route MIDI OUT below.

Pick your key count, then SET LOWEST KEY and press the bottom key on your piano. Songs fold into that range, octave-true.

OUTPUT — YOUR OWN SYNTHS
{{ ot.label }}

Route the game into your purchased synths: create a virtual MIDI port (IAC on macOS · loopMIDI on Windows), point your DAW or standalone synth at it, then pick it above. Your keys go out on CH 1 · the song's auto notes on CH 2. Turn INTERNAL SYNTH off to hear only your rig.
