Performances
A Performance is a 16-part combination of Sounds. Parts can be assigned their
own MIDI channel for multi-timbral reception, be set to the same MIDIchannel for
layer and split options, and be individually muted.
Parts can be set to a global "Stack" channel, which can then be defined as any
channel (1-16). In this way layered or split setups can be quickly matched to a
given input channel by simply changing the Stack channel setting.
Each Performance contains a custom DrumKit
