How do you know what sysex is being sent are the Biab styles and demo laced with sound canvas syntax? I have encountered this facing the korg wavestation as well. Could it be that Roland, Korg and Yamaha used different midi formats? Or is that a rumour about there being some incompatibility manufacture specification quirks? I have now tried exporting midi with several Korg synths and encountered the same issues. I think I'll try this into Realband see if it is a smoother process. Realband is a Rhythm sequencer while Sonar is a musical store of instruments and is basically buying a music store that is why I try to make my final output in Sonar x3 producer
