I'm was trying out SoundDiver 3.1pb2 under OS X 10.4.7 with a MOTU MIDI Express XT interface. SoundDiver was never able to see/communicate with my Casio VZ-8M, and all the patches that were sent to my Yamaha TX81Z were corrupted by the time they got to the synth. Is there an issue between it and the MOTU interface? Does anyone else have any ideas on what the issue could be? Thanks in advance. Ivan
