one piece. the bassdrum but it can make a lot of different sounds.

you can also buy a pcb from m.bareille.
on electro-music there's a thread with the cv-in mod

another good project seems to be this one

Do you want an entire kit or simply one add-on?  I've got a whole whack of e-drum schems.  Thomas Henry had a bunch of interesting drum projects that he was selling/peddling out of his former Midwest Analog Products site.  One alternate source people don't always consider is the individual drum circuits embedded in the older drum machines like the Roland TR-606, the PAiA programmable Drums, etc. (e.g., check here:  http://www.synthmuseum.com/roland/roltr60601.html ).  There were a bunch of simple drum projects in Polyphony, Elektor, and Electronics Today.  Craig Anderton had a nice little circuit for a kick drum in Polyphony as well as a swept "syndrum" unit.

Normally the microphones that exist in these things are triggers for us to 'knock' right? Well, isn't there something that automatically does the triggering, so that the drums play automatically and i play guitar along?

With this little thing i have to be triggin' it all the time, right?

Yes they're called SEQUENCERS! Smiley

Add cv input to your modules and your done!

I did some bassdrum modules but I'm looking for a simple snare one.
I guess a noise source needs to be added for simulating the muffle.

Simplest solution is a 555 timer, run at a low frequency.
Google for  555 metronome   and you are sure to get  a million circuits. The click will trigger your drum.
But, once you want to make something that does actual beats......boom cha cha etc ....... it's a lot easier & prob cheaper to gut the percussion out of a discarded home organ!

I have one of these. I haven't listened to the samples but mine gives all kinds of cool swoops and sweeps. I guess it could do a bass drum sound but the synth type stuff is more fun.

Come to think of it, my one book has a diagram for a drum thing. It says by tuning the knobs you can get a bongo and other stuff. I've never tried it. It is the Forest M. Mims Getting Started in Electronics. I picked it up at Radio Shack around 10 years ago; I don't think they carry it anymore.

Come to think of it, I think I have the 555 timer one, too. I wish I knew where they both were.

Depending what your situation is.. the cheapest (though not portable!) solution is a scrap computer running a free drum sequencer thru
the soundcard. Those Win 3.1 programs still work just as well today, you know!

Another alternative, which I see people use, is drum loops on an ipod or mp3player.  Particularly useful if you want a drum accompaniament whille wandering around with an acoustic  icon_wink
