Thanks for the fast reply.I don't know.I'll be getting a scsi card for my pc soon so i'll try it that way.I could also try midi transfer of a program but i'm not sure it will be recognised..I only use midi for transferring .wav files I'd love if i could also transfer .rex files but haven't tried that.Do you by any chance managed transferring a chopped loop via sysex?I wonder what conversion the programs that succesfully do that use.
