Just got hold of one this week finally and I absolutely love it, haven't really played with the sequencer, but as Pads and Knobs it's great. I can see the knob action takes some getting used to but I like having the fine control. The Pads feel good and work well as CC triggers, I've set up a patch for dubbing the RS7000 this way with FX send and LFO Speed triggers which has added a new world of fun. It's great fun for drumming it has a really nice weight to it when sat on your knee.
As always though I do have some requests:
It would be great to be able to use the aftertouch as a CC controller instead, I don't see a way of doing that in the control center, I sort of presumed it would. Maybe it isn't possible to implement but to have 16 pressure CC controls would be a very good feature.
The only other thing I'd like is a transpose button for the pads when used as notes so it can be used more like a keyboard, at the moment I've used 4 presets to cover the range each starting on the next C up. Not essential but would be great, and if you think about a custom mapping for drums transposed up an octave it would instantly give you access to the next set of sounds with hardware such as EMUs etc... where there is often another kit with the same mapping.
Yep a very nice solid box
