Andrew,

Yes, the synth shows up as "Edirol VSC". I believe that this version came along with some music software which I installed from Cakewalk (either Music Creator or Sonar).

When I tried to install the Edirol synth which comes with BIAB as you suggested, the installer complained that there was a more recent version already installed and then the installer wouldn't proceed.

I also looked in Control Panel / Add/Remove Programs, but there was no listing for the Edirol or Roland synth there. I hesitate to uninstall the severall CAkewalk products just to get rid of the newer Edirol version so that I can try the one which came with BIAB (although there is no guarantee that I won't have the same problem with that version).

I wonder if I need a newer version of Direct X or something? Does this probelm occur when you have the BIAB version of the Edirol synth selected with BIAB?

Thanks again. At least I feel we're a bit closer to knowing what is going on (although I certainly don't see quick solution).
