Looking at the MIDI implementation pdf for Roland JD-XA (available here: https://www.roland.com/us/support/by_pro...lang=en-US), I can see that the bank select matches what is sent if you use a "Patch Select" message in MobileSheets. To be clear, a "Patch Select" is not a standard MIDI message, instead it is composed of two control change messages followed by a program change message, and the messages are:
CC 0 MSB
CC 32 LSB
PC Value
This is exactly what the manual calls for. Interestingly enough, it says the internal memory starts with MSB 85, and the LSB 0-1 is internal program, 32-33 is USB. So if you wanted to select the 5th bank in the internal memory, you'd send a "Patch Select" in MobileSheets with values 85, 0 and 5. So just enter 85, 0 and whatever bank you want to switch to on the new MIDI command dialog, and you can tap the test button to try it out.
Let me know if you need more than that, or if this doesn't work for some reason.
