I got Yamaha CP5 and I try to define banks so that I can use its instruments from the computer (using the Rosegarden sequencer). Each bank should be specified by a MSB/LSB combination. The data list gives listing of all instruments, but it gives MSB/LSB values only for performances (combination of several parts, with different effects etc), not for voices:

Is there a way to access individual voices via MIDI? Likewise, is there a way to access drum banks?
