you can't use a drum trigger on it's own to drive the QS6 because the QS6 needs MIDI mesages whereas drum triggers send minute chages in votage usualy from a piezo-electric device. You'll also need a drum machine of some sort to convert the trigger signals to MIDI.
There is another option but I believe that it's a serious DIY electronic project and it allows you to do such a trigger to MIDI conversion.
If you're up to that I'll try to find some more info
