isn't it also possible to use midi to trigger the sounds in the 
machinedrum? and I don't mean with a sequencer. 

using either v-drum pads or something like the Roland SPD-20, 
couldn't you trigger any number (only limited by the number of pads) 
of sounds? I hope this is the case, because I was considering to buy 
something like the spd-20 to allow live playing of my MD.
