These 5 controllers can be used to adjust any parameters associated with the circuitry that produces sound. For example, if a device uses looped digital waveforms to create sound, one controller may adjust the sample rate (ie, playback speed), for a "tuning" control. If a MultiTimbral device, then each Part usually has its own patch with its respective VCA, VCF, tuning, sound sources, etc, parameters that can be adjusted with these controllers.
NOTE: There are other controllers for adjusting VCA attack and release times, and VCF cutoff frequency.
0 to 127, with 0 being minimum setting.
