From David J Hoskins:
Pitchwheel (64-Bit) plug-in freely alters the pitch and timbre of a sound in real-time. It has a large, easy to use dials and simple parameters making it a fast and creative effect unit. It can give fine tuning control from fractions of a semi-tone to huge multi-octave pitch swings. It features MIDI controllable with multi-octave adjustments, and fine wheel detuning, eight note chords for creating easy vocal harmonies and effects, unique inertia settings for springy vibrato effects, and wild pitch swings, and ideal for experimental and live performances.
