On the MD, the inputs can be used as triggers of sounds and midi machines. Sending a mix of percussion through a filter to the inputs, then using the filter to bring out different sections of the percussion mix along with playing with the trigger sensitivity to determine if every sound of the input signal triggers or just the loud hits. This ends up triggering internal md sounds or external midi gear or sending a cv trig (if you have a UW, I don’t, I imagine it can get over the top crazy triggering sampling and playback). The on the fly variation is superb. Try it with and without the input source in the audio mix.
