Use the MIDI CC menu to choose to which MIDI Control Change number STACK MODE will respond when using the CC setting.

NOTE: When using CC, all Parts added to the Stack Mode Grid will be triggered simultaneously when notes are played, even if their Regions are outside the CC value range, and not outputting audio. Therefore, this feature can put a high demand on the CPU on your system.
