My bro has this same set...This thing is amazing for practices, everyone can turn down and play at a level where you can actually talk over the sound...and you can play all hours of the night without bothering anyone!

djlotus51 - Thanks for the plug! That's exactly what I use my kit for. It's amazing what a difference rehearsal makes when you can control the volume of the drums.
lonewolf - The module has (1) MIDI in and (1) MIDI out. You can use the module to trigger sequencers/software/etc.; or you can go the other way and use keyboards/sequences/software to trigger sounds from the module.
