how it works
-
your webcam feed appears inside a circular viewport (the
"ocular").
-
a thin radar line rotates clockwise at a bpm you
control.
-
sample points sit along the line — one per scale degree.
-
when a point's pixel brightness crosses your threshold,
a midi note fires.
-
choose a scale, a root note, a spread curve, and up to
127 voices.

midi setup
requires a chromium-based browser (chrome, edge, opera,
arc). firefox & safari do not support web midi.
use iac driver (macos),
loopmidi (windows), or
snd-virmidi (linux) to route midi to your
daw.
