MIDI commands are tied to songs, not to setlists, so it's not possible to tie the "setlist number" to something used in a MIDI command with the current design/implementation. Song versioning, when implemented, could provide one way to tackle this. Regardless, I don't know exactly what you are trying to do with the drum pedal. You said you want to select a song on it - where is the documentation for it that shows what MIDI commands it supports? You can't just send any MIDI commands you want to a connected device and have it perform an action. It has to be something that the MIDI device supports, so it has to be listed in the manufacturer's documentation/MIDI list. 

I do know that with the beat buddy you can control the tempo by sending two control change messages, so that is something that I can make easier for users in the future.
