Hey everyone! Just finished building Pitcher — a chromatic pitch shifting synth plugin with formant preservation.
What is it?
Load any WAV sample and play it across the keyboard. Pitcher shifts the pitch while keeping the natural character of the sound — so vocals still sound like vocals, not like a sped-up tape.
Features
- Chromatic pitch shifting — ±24 semitones
- Formant preservation — keeps vocal character natural
- Grain-based algorithm — adjustable grain size for smooth transitions
- Stereo width control
- 4 factory presets: Natural Voice, Chipmunk, Deep Vocal, Robot Formant
- 8-voice polyphony
- SDK v2.1 — uses the sample loading API
