Hey, you're the one who wanted the "sampled drums, like in bonk" :-) I still don't think its gonna sound great, but I've been surprised by some of the stuff you do before.
And yeah, from a practical view, I do think the built-in drum stuff is gonna give acceptable drums, and for far less space than a sampled set. But If I get the voice stuff working, and it sounds okay, I'm gonna have our pac-dude scream when he dies. Even if it takes an entire 8K bank and 4 songs to do it :-)
