Pitchwheel - Version 1.00 The Pitchwheel plug-in changes the pitch of a sound without changing it's length. It has a large, easy to use dial and simple parameters making it a fast and creative effect unit. It has a range of two semi-tones to two octaves, which gives you control from subtle tuning changes to wild swings of pitch. The user pointer acts as a desired pitch change, and the actual pitch is produced by smoothing and inertia controls.
