+Maniac Bounce is a one-channel MIDI/CV delay with dry-through, bounce pitch, and a velocity LFO on dry notes and repeats. Main sets delay time (fader up = shorter) and echo retention together — short delays fade quickly, long delays keep bouncing. Shift + fader sets the bounce interval bipolar ±24 semitones (default about +6 st). Button + fader sets Vel LFO rate and depth coupled (up = faster and deeper); the LFO modulates velocity on every note including the immediate dry hit. In MIDI→CV Gate mode the same LFO shapes gate pulse width instead.
+
+Each note auto-gates to about half the frozen delay period. Bounce alternates +interval / −interval per repeat. A new NoteOn on the same pitch kills the prior chain for that pitch (poly with same-pitch kill). NoteOff does not kill the trail. Short button tap mutes new input while the trail rings out; long press panics unless you are holding Button+fader for Vel LFO. White button flash on input. Free-running ms delay only — no clock sync.
