slide around — no wrong notes.
C major
0 voices
touch the dark and slide. left–right is pitch, up is loud. esc hushes everything.
Voice & Feel
four voices, none of them a bare sine — pick one, pick your range, and every finger you land (up to five — a whole hand) sings in its own colour. y-axis is loudness: the bottom edge whispers, it never goes silent.
Echo
not a looper — a canon. the ghost starts singing echo-time after your first touch, so with a short echo it's chasing your finger while you're still drawing. two repeats, each quieter and paler, then gone for good.
Scale
the stripes on the pad are the scale — roots in amber, note names along the bottom. turn gravity up and your finger falls into them; turn it to zero and the whole space between the notes is yours. the non-octave scales (slonimsky, harmolodic) wrap at their own period, not the octave.
