Well, well... Things are moving. A RackBrute 6U has been ordered this week.
Starting from a first approach and your expert advices, then after watching some Youtube videos (as you guess... ;-) I have led with this set (to be linked with Mother-32, DFAM, 0-Coast, System-1m, KeyStep, BeatStep pro, SQ-1).

My piggy bank is shaking.

It would be great to read your opinion.
