You can hook up the FD4 to the computer with midi cables; that will allow you to use Cakewalk to control the FD4. You can't, however, transfer tracks via midi cables.
I think
the FD-4 has digital audio outputs, if this is true, you could record the tracks into cakewalk two at a time, assuming you have a soundcard with S/PDIF (digital audio) connections. This would allow you to transfer the tracks without losing any quality.
You could also rerecord the tracks with the analog outputs of the FD-4, and the line-in of your soundcard, this will degrade the quality of the sound.
Also, if you have a scsi zip or jazz drive, you can plug that into the fd-4, copy the tracks, then plug the zip or jazz into the scsi card on your computer (scsi zip and jazz drives generally come with a scsi card, in case you don't have one), and copy the tracks on to your computer. As long as the FD-4 uses some windows recognizable audio format, this should work.
Hope this is useful
