According to Les Cargill at worldnet.att.net, there is a way to get all the single tracks out from a TASCAM 488 MkII, although it's not pretty:
Now, to be perfectly honest, the first time I tried to dump my 488's tracks to my new digital recording setup, I went to this very page, and...couldn't quite understand what he was getting at. So here's now I did it. Remember that you'll always want to pan odd channels to the left (when appropriate) and even ones to the right:
If you don't like some of my connections for some reason, you could try
using the Insert outs on channels 1 and 2 like Les suggests.
Les wrote me some email that got caught by a spam filter, but luckily I retrieved it from the bit bucket. Here are his elucidated instructions:
Your way will work, too. I forgot about the sync out, or assumed it was switched to the sync switch, which would defeat dbx.
The (dis)advantage to "my" way is that the strip EQ for each channel is still intact. Not sure about the synch out, I think it's pre-EQ. No EQ on the Tape Cue circuit either. I call it a (dis)advantage because it might be nice if you could bypass EQ.
On Page 39, "Features and Controls" of my copy of the manual
( one of the pages that folds out double), the ASSIGN buttons are documented
as item 15, and MONITOR buttons as item 23.
