For me, a desktop controller makes more sense - it seems that 
it would be quite difficult to play an instrument in a rack mounted 
position!  RE:  layout, either would work for me, but as pointed 
out, a KB configuration might make playing it easier. The big 
question for me is - what type of power supply? I don't have any 
more rack space (for a bus connection), but was wondering if the 
TKB may be mains supplied (or maybe a - YUK! - wall-wart).
