Been practicing drums on the rock band drum set without being plugged in. It seems good for practice. It bounces well and you can do those quick triplet drum rolls. Well you can also plug this into the computer and get a program to play a drum machine. I've seen one with wave files and one with midi. There is a slight delay, enough that drumming isn't very good. It may be my computer as the controller action seems instant when looking in the control panel and seeing which buttons get hit. So now I want to look at using this for triggers. You could use any wave file you want. You can use the pedal to switch the drum triggers to a secondary. You can even use a second pedal. So you can have 8 triggers easily. There are cymbal extensions, so up that to 12. Add another pedal and up that to 18! Add another drum set and up that to 36! Anyway, going to see what I can set up.
