Yep MT,
Everything is electronic! Bass, cymbals, toms, snare, the works. Pretty cool eh! The drum heads are covered with a nylon mesh with the triggers underneath.
My kit has a mesh snare but the rest of the trigger pads and cymbals are rubber but they are all 2 zone and pressure sensitive which gives me the feel of an acoustic kit.
They sure have come a long way since Pseudo Echo!
I played acoustic kits for many years but there are so many advantages to an electronic kit now they have excellent sampling.
1. They never go out of tune
2. I can choose from over 80 different drum kits and have a stack of built in play alongs(songs where you can mute the drum track and practice)
3. When my boy's asleep, I can whack on the headphones and still play.
4. Never need to mic up for a gig.
5. The drum brain is also a midi sequencer with heaps of realistic sounding instruments.
If you like, I'll sample a composition of me on drums with a midi sequenced arrangement and whack it on mp3 for you.
