Hi Morphyx,
in the DMpro you can load a new drumkit (from 'ProKit' to 'TechnoKit') using a bank program change as you usually do on a synth - you don't have to press any button (you virtually press it by sending a MIDI message). You can use only one drumkit at a time (due to their big dimensions), you can't play drums from different drumkits at a time - it is ok for live drummers but quite annoying in the studio. As I totally dislike DMpro factory drumkits, I had to build my own drumkits (but I must admit it is a quite fast process, and editing of new sounds is very good). Changing drumkits is quite slow - it takes about 2 s to load the whole drumkit and you can't play until it's fully loaded. If you have to play sequences (or sounds/samples you put directly on the PCMCIA card via MIDI by SoundBridge software enclosed with DMpro...), you can trigger them from the card by midi or by audio triggers. Bye
