A softer harmonic balance with room around each event.

A working phrase, then an edition
Keep one version.
Try another.
Save an edition with a name that means something to you. Duplicate it before changing its rhythm or register. Compare real note and timing differences, then return to the one you want to hear.
- Notes and rests with explicit beat lengths
- Equal-pitch ties that hold one continuous tone
- Tempo, transposition and independent phrase editions
- A WAV rendered by the same native sound engine
A few useful details
Simple controls.
Actual sound.
What makes the sound?
Original oscillators and envelopes create the audio on your device. The app does not use recordings of performers.
What does a tie do?
It joins equal neighbouring notes without a new attack. A rest remains silence, and every beat contributes to the duration.
What can I keep?
Save and compare editions in the app, or choose a WAV, text sheet or project export. You decide where an exported file goes.
