	~~Its not known yet~~ how ~~keygroups work, but it appears its a set~~ of ~~properties that can be assigned~~ to ~~splits of every programs that overrides some of those splits' parameters, determine their max polyphony, their volume, their "~~priority" and a ~~few other things~~.		Keygroups are used to allow finer control on how the audio engine allocates the limited amount of voices to the presets. They define a per group priority and a range of voice channel available to each, along with the maximum number of simultaneous voice channels each can used.
