Paint shapes in white. Each one becomes its own instrument —
and the drawing inside its box is the part it plays, read left→right
like a piano-roll. A scanning playhead sweeps every box in time.
Draw a shape — its box turns into a 16-step sequencer.
Where you draw is the music: ink height → pitch, so a rising line is a
rising melody; gaps are rests; a dot is a blip.
How you draw is the sound: dense/round → soft pads, thin/jagged →
bright plucks with more movement & echo.
Each box is a voice you can mute — pick the 🔘 Toggle tool and
click a box to turn it on/off.
Set the key, scale and tempo to re-voice everything live.
Tip: hit ▶ Start sound, draw a wavy line, then a few dots above it.
