MIDI: CC116:1@0 - will load the first drumset on your list
CC116:<value>@<channel>
<value> is the 1-based position of your drumset in the list on your pedal (not 0-based as when doing song changes)
<channel> is the channel your BeatBuddy is listening on (0 is probably fine)
You can chain commands: MIDI: PC0.0:0@0, CC116:1@0 will load the first song in the first folder and then change the drumset to the first drumset on your pedal
For good measure: MIDI: PC0.0:0@0, CC116:1@0, CC106:1@0, CC107:1@0
will change to the first song in the first folder, the first drumset, and set the tempo to 129bpm
CC106:0 means CC107 sets tempo from 40 to 127
CC106:1 means CC107 sets tempo from 128 to 255
CC106:2 means CC107 sets tempo from 256 to 300
