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. These controllers would be used to adjust sound parameters for which there are not already other, defined controllers.
0 to 127, with 0 being minimum setting.
