I've seen that, and I've seen sets they call electric which appear to be acoustic drums fitted with "triggers" that let you drumm electronically, but trigger hammers to hit the drum head (It's been really really busy today, that's just what the pics looked like).

One of my customers that has a band happened to come in today, and so I asked him. He suggested these triggers but I really didn't get to talk to him about it before someone else came in. But if that's how these triggers work, then it doesn't help the "I need it to be semi-quiet" aspect.

Though, I suppose maybe I have the idea backwards, and triggers really just mute the drum but signal the electric "virtual" drum to produce a sound. Hmm...
