The controller numbers used by QuickTime are mostly identical to the standard MIDI controller numbers. These are signed 8.8 values.
All controls default to zero except for volume and pan.
Pitch bend is specified in fractional semitones, which eliminates the restrictions of a pitch bend range. You can bend as far as you want, any time you want. Global controllers respond when the part number is given as 0, indicating the entire synthesizer. A modulation wheel adds a periodic change to the volume or pitch of a sounding tone, depending on the modulation depth knobs. This controller controls the foot pedal.
