Hey,
I have a S760 (and I love it), but I aggre with Fernando, the S760 is dead (thanks to Roland... :-( ).
About Sample dumps:
SCSI dumps are only supported in Mac platform, Win9x does not support SCSI transfer with the S760. If you're using Win9x, forget SCSI card and save your money.
Most editing software, including Steinberg Wavelab, Recycle, and SoundForge will only support MIDI/SDS transfers, but it´s very sloooowww.
