Postscript:

I took time to test the sound of Cakewalk TSS-1 more specifically and I have to state more precisely:
Realdrums sound good or rather better than with Coyote, also the bass.

The sound of the songs would also be better of course, if I'd match the sound volume of each track exactly.

But the cons outweigh the pros: Mainly the sound of the vibraphone, also of strings/pad and piano, that sound more artificial in my estimation.
