Draw a shape. Hear it. Take it to your DAW.
Every line snaps to the key and scale you picked, so no shape can land on a wrong note.
The stage is one loop. Vertical lines are beats, numbered lines are bars. Gaps in a line are rests.
Your line sets the notes. The rhythm setting decides how they hit: held, plucked, arpeggiated or offbeat.
Draw low for a muffled, filtered mix and rise to open it up. That curve is your build and drop.
Export gives one zip of .mid files, one per layer. Drag them into Ableton, FL Studio, Logic or GarageBand.
