Don't forget the Ensoniq samplers, I use 'em with Macs, they are what got me into Macs in the first place.
Basically, EPS16+ works with Mac scsi that is what I have and use. I gather the EPS scsi wasn't that great as it was still being invented at the time so might not work. ASR scsi I think does work with Mac scsi. The Mirage doesn't have scsi only MIDI for which I wrote a editor for Win95/98, I think someone has now done a better version. BTW: Macs do not handle Ensoniq floppies, same old problem, simply different tech, don't waste time on this, Giebler has EDM for DOS which does this perfectly.
On the flip side, I didn't find ANY scsi sample transfer on Win platform, I tried all I could find, there was always some problem, so I moved to 68k Mac and BINGO! problem solved all my wave data transfers are via Mac scsi
