KBN-G — Kinetic Bouncing Note Generator

Bouncing balls that play in key. KBN-G takes the physics arena of its
sibling KGB-G and turns it melodic: four balls fly around a field, and
every wall they strike sounds a pitched note. Each wall is split into
three zones, and the twelve zones climb the scale you choose — so no
matter how chaotic the bouncing gets, every note lands in key.

Pick a root, octave, and scale (ten to choose from, Major to Whole Tone),
and the arena labels each zone with the note it will play. Each ball is
its own monophonic voice with a gate + note output pair, so KBN-G can
drive up to four synths at once — four independent lines weaving in and
out of each other. Ball-to-ball collisions ring the root note as a
natural anchor.

Drop a horizontal or vertical trip line across the field and it becomes a
ratchet: a ball crossing it fires a burst of notes that ladder up or down
the scale, spread across one grid step — instant arpeggios triggered by
motion. Add per-hit velocity, probability, and full CV control over speed,
position, and randomness, and you have a generative melody engine that
never plays the same phrase twice.

KBN-G makes no sound of its own — it’s a pure CV/note brain that plays the
instruments you already own.
