just curious: are the guts of the sequencers essentially the same on these boards? was at the store the other day but didn't dive into the 2100 sequencer at all. I have the 9kpro but was very surprised at the quality of the sounds and styles on the 2100 -- that thing is surprisingly deep -- and I'm wondering if they've put a different architecture in it. you know, one where "Quick Record" is actually quick.
