If I'm not mistaken, the DMT8-VL included a SCSI port for backing up the project to external drives (JAZ, etc.), but I don't think the SCSI option was useful for mastering to two-track and don't know if the data is stored in a format compatible with a PC using a SCSI bus.
If all you want to do is get the music you have already recorded on
the DMT8-VL into a computer so you can burn it to CD , all you need is a soundcard, the appropriate cables, and a program that will let you record the audio to your computer's hard drive as a 16-bit, 44.1 khz stereo .wav file (Goldwave, Cool Edit, N-track, whatever). Hook the stereo output of the DMT8VL into the line inputs of the soundcard, set the computer to record, and push play on the DMT8VL and mix away. Once you have the .wav file saved any CD-burning program should be able to handle it. Better soundcards and soundcards that can make use of the optical output are the icing on the cake, but if I'm not mistaken,
the DMT-8 and DMT-8VL actually mix down in the analog realm, then convert the signal to digital for the optical output. If you have a really good soundcard you might be better off recording from the analog outs and letting the soundcard do the conversion.
If you want record each track separately on the computer so you can mix it there, you'll need a soundcard, cables, and a multitracking program (Cool Edit Pro, N-track, Cakewalk, whatever). Hook up the individual track output jacks on your DMT-8VL (I know the dmt-8 has them, but does the VL?) straight to the soundcard's line inputs because you are mixing on the computer so you don't need to bother with the the mixer portion of the DMT8-VL. It's easiest if your soundcard has 4 or more inputs, but since both the DMT8VL and the computer are digital devices with pretty consistent timing, it's not hard to record each track individually into the multitracking program and then line the tracks up inside the multitracking program to synch them up again without worrying about MIDI synch (I have done this with my DMT-8 without any timing issues).
Hope this helps and doesn't just lead to more confusion,
