The musician starts it.

The device understands it.

The instrument answers.

Three ways into the music.

Read it. Hear it. Strike it. Each tool owns one job and keeps the signal close.

02 / Principles

Close to the musician.
Far from the cloud.

The shortest useful path is usually the best one: instrument to device, device to feedback, feedback to the next attempt.

01

Process on the device

Scores, microphone analysis, touch and motion stay in the local performance path.

02

Start without an account

No identity layer between the musician and the first useful action.

03

Connect to real tools

Standard files, CoreMIDI, Web MIDI and existing music hardware remain first-class.

03 / Availability

Start with the instrument that is already live.
