Normally, to send program changes from an RD2000, you enter three numbers: an MSB code for the instrument, an LSB code, and a program change number. I would like to send program changes from the RD2000 to move from one B3X preset to another. I'm running B3X on an iPad, controlled by a Roland RD2000. iPad® is a trademark of Apple Computer, Inc., registered in the U.S. B3X iPad: Send MIDI program change for preset.
