let me rephrase my question.  ON my triton le i first sequence my 
tracks like this:  first i step record the drums, kick, snare, i 
hat. i loop each drum track:  i choose loop from measure 1 to 
(whatever) 

what i like about the triton sequencer is the looping function, i 
can step sequence 1 measure of hihats and snares, and 3 measures of 
kicks and they play along each other looping.  can the mp-7 
sequencer do this? what about the mpc (im sorry but i dont remember 
if it can in this style)  can either sequencer loop via measure 
selection? thank you for your response
