Thank you for your reply. Yes, it seems SCSI transfer with the s-760 is quite limited on a PC. I did some research and found out that Recycle (up to version 1.6) is supposed to handle SCSI transfers (I haven't had the time to try it myself). To get it working you should install the ASPI drivers for DOS, make sure the WIN95 SCSI drivers are disabled and also check that the s-760 is connected to MIDI as well.

It's sad to hear that Recycle has dropped the SCSI support for the s-760 from version 1.7.
