I'm still workin to complete all cable and wiring, and after i will test the software too.
My megadrum is build with the synthex kit 2.8 and the precious help of Dmitri, with his BIG patience!

I bought the box in a simple electronic-store about 30 €, with stereo jack connectors, microphone cable, piezos and a lot of stuff.
The original kit was a "drummond dd602" bought as BROKEN

added the second piezos for the rim

(the internal connector was stereo jack)

and add on two cymbals the choke strings

I have a Roland cy5 as hihat and FD8 as pedal, yamaha pcy15 as Ride (3 ZONES!) and a DIY snare with crossbar (old video http://www.youtube.com/watch?v=4CihZXUc77g )
