Nice tracks, everyone!
Is none of you using the Rev2 for "drums" or percussive sounds?
And are you programming notes in a DAW and sending to Rev2 or do you play "live" on the Rev2 and record audio?
You can make any classic analog drum sound (bass, snare, clap, hihat, cowbell, toms) in excellent quality with the rev2.
I sometimes also use these sounds (as samples). The only thing is the workflow: I realised, that for me it is much easier to build the beat with the TR-8 because I can edit the drum sounds while building the beat instead of first editing the drum sounds, sampling them and then building the beat.
Actually, the toms in "etwas glänzt" are Rev2 sounds

The answer to your second question: I usually play the Rev2, record the midi notes, quantize them and record audio afterwards.
