Hi ewan,

I don't have exactly the same setup as you have, but a lot of your
problems sound very familiar to me. (Even though I didn't have them
that bad.)
Anyway, here is my advice. You should definitely patch CAF with
AB040FIX.TTP which you can find on Magnus' homepage. This at least in
my case solved all my problems with cracks, pops, distortion or
switching output channels. I also tried NVDI in ST-Ram befor the
patch but it didn't make a difference.
I also should mention, that I am not using Doug's TK driver but a
more or less original driver version which was patched by Slobodan
Curcic to work better especially with MagiC.
The 16 Track mode though is still not working. Maybe if you try
it with Doug's driver and DMASNOOP. I don't know about that. I for
myself never use more than 8 Audio-tracks anyway.
Let me know, if any of this has been of some help to you.

Take care.
