think about it this way, you can use a trigger finger or pad kontrol to trigger synths too, well at least the pad kontrol can, it has a place for a/c, and midi i/o. so you can either use it to trigger software and as a midi interface, or you can use a/c and have midi out to a synth or drum machine and trigger it using the pad kontrol. also pad kontrol has flam and drum roll, xy pad, and it feels very nice too
and flashing lights.
