Overview
The Choppa is vocal chopping without the razor-blade work. Load it on a MIDI track like an instrument, drag a vocal file onto it, and it detects the transients itself, so the slice points land where the words actually start. Then you play it: a MIDI clip gates and re-pitches the vocal live, with three trigger modes — sync to the transport, step through slices in order, or map slices across the keyboard. Switch Re-pitch on and each key plays its slice at a new pitch, relative to a root note you set. Varispeed gives the classic tape-chipmunk chop sound; Time-Preserve keeps every chop its original length while the pitch moves; and Formant Preserve keeps the singer's vowels in place, so chops pitched up still sound like the same voice. Gate, one-shot, and loop hold modes cover stutters, chops, and pads. The loaded audio is saved inside your project, so sessions reopen exactly as you left them.

Computerizer gives you thirty digital-flavored effects in one simple plugin, and you can stack up to three at once. Choose your flavors, turn Amount, and go from light lo-fi texture to chopped-up robotic glitch.$14.50$29VIEW →Flutter / Motion FX · Audio EffectThe Featherer
The Featherer makes rapid wingbeat movement — volume, resonant filter, and stereo pan all flapping together from one motion signal. Run it free, lock it to tempo, or fire it from MIDI.$14.50$29VIEW →Rhythmic Motion Effect · Audio EffectRatMotion
RatMotion gives anything that sustains motion locked to the host clock: four lanes (Stutter, Volume, Pan, Filter), each driven by an LFO wave or a step pattern you draw on an oscilloscope, with swing, MIDI retrigger and a harmonic tremolo mode.$9.50$19VIEW →
