ReadonlyidThe group bus channel (a mix-kind ChannelId).
Optional ReadonlymainThe group→main send level (linear). Absent is unity (1). Scales the whole group's
contribution to the main mix on top of the group master.
ReadonlymasterThe group master's linear gain (0 = silence, 1 = unity; >1 boosts).
ReadonlymembersThe input channels routed into this group.
Readonlymutedtrue while the group is muted — its whole summed output is silenced.
Optional ReadonlytoWhether the group feeds the main mix. Absent is true — a classic sub-group folds
back into main. Set false to run the group as a stem / standalone output that never
reaches main.
One audio subgroup: the group bus id (a
mix-kind channel), its master linear gain, its mute, the input channels assigned into it, and how it folds into the main mix.
