As Peter already mentioned, make sure that MIDI channel 1 (or whichever 
channel you are using) is set to Layer A.  By default it should be.

Program changes are much easier.  Program Change (sometimes called 
"Patch Change") 1 = Cue 1.

If you are doing it in hex, would just be 0xC0 followed by the cue 
number (for MIDI channel 1).  So, simple - just two bytes.

If you are using a lot of cues (need to get beyond 127), you just put a 
bank select before it, so a B0 00 00 C0 01 would be Cue 1 (bank 0, cue 
1) and a B0 00 01 C0 01 would be Cue 128 (for each bank, add 128 to the 
number).

I'm not familiar with that board, but it's possible it can easily send 
Program Changes anyway without even dealing with the hex.

Hope that helps,


Jon
