The format of the returned output is “1:S1[,S2] 2:S1[,S2] ...” where the 1: and 2: are incrementing destination
values, followed by one or more source values (depending on the number of system levels).
Special source values

The above example shows that Preset 1 would cause Destination 1 to be connected to Source 1 for both levels,
Destination 2 to be connected to Source 2 for both levels, Destination 3 to be connected to Source 6 for Level 1
and Source 7 for Level 2 (break away) and Destination 4 to be Muted for Level 1 and “No Change” would be
made for Level 2.
