GSDSP MagicPitch

De-tune harmonics, fatten up your drums, create otherworldly vocals - it’s all there! Easily and quickly apply separate pitch and frequency shifting per frequency, or multiple frequency ranges. Mix them, modulate them, spread them, run wild, and create truly original frequency transformations from subtle de-tunings to extreme effects from outer space.

MagicPitch is an AUv3 audio effect plugin. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).
