I am guilty, I compose mostly midi, and when I moved the old 8-track out, I found myself needing a few tracks, for expressive instrument, a vocal, or maybe an acoustic picked track, so I got an MD 4-track. It has all the sync capability, and integrated perfectly, giving me four digi tracks to work with, without going DAW. I do not put entire tunes on it, just an occasional track. I really found the benefits in VO work, as said earlier; Radio/TV has great use for these things. When I am are working with a script, and talent, I just tuck it under my arm and go. I just # the lines, and we are off, take, take, take... When finished, I edit, good, no-good, good, etc. After editing, which takes minutes; all the #'s fall in place perfectly with the script. You can then just thumb through the cuts. I think the sound is pretty good, but stay away from generations. I have been told that adat W/TC would be better for the music. They are not very expensive, and might be a consideration, but, it could be back to analog too, just won't sync up as nice. I will continue to use MD in V/O production.
BTW, Fletcher, LOL, there is nothing like a DX-77 off an MD.
