====== MIDIbox 3396 ======
This is a page for collecting ideas on how to build a synth based on the Curtis Electromusic Specialties CEM3396 IC chip, controlled via PIC of course. This chip is for example used in the Oberheim Matrix-1000 synth. It is out of production, but can be found at [[http://search.ebay.com/search/search.dll?from=R40&satitle=cem3396|ebay]] from time to time.


===== Data Sheet of CEM3396 =====
First please take a look at the [[http://www.synthtech.com/cem/c3396pdf.pdf|CEM3396 data sheet]].

**FIXME**



===== Additional info, A Readily available source of CEM 3396 chips: =====
try contacting marcus at: cheetahrepairs@lycos.co.uk
The CEM3396 is £6.50 each or a complete set of 6 for £32.00.

I dealt with him whilst repairing one of my two matrix 1000's
This is an excellent sounding chip & would benifit highly from the Thorsten Treatment :)


===== CEM 3396 contacts of interest, working on firmware for the Cheetah MS6, a Matrix clone: =====
See: http://www.maad.net/ms6/index.html
Contact: kristofer@maad.net

This guy has patched up the firmware of an old matrix 1000 clone by cheetah, known as the ms6; to work properly ..amoungst other things.
He also is in the process of rewriting a firmware for the module from scratch; and may have already made some progress...
I guess this might be someone worth talking to on furthering the MIOS effort to utilise the CEM3396; Im sure he will have plenty of insight to offer.

Oh, and he's selling 3396's on his webshop too.


See his links page for other 3396 things:
http://www.maad.net/ms6/index.html

And found on the above links; Heres another guy whos hacked the firmware..

oh and one final place that has a handful of cem3396's: http://www.synthtech.com/cems.html

===== Project - Turning a Oberheim Matrix 1000 / cem3396's into a multimode Xpander =====

I have done the damned hard groundwork for the hardware nessursary to turn a humble cem3396 chip into a multimode filtered monster, like the Xpander & M12.
Sofar, i have created a Beta pcb layout to facilitate this, however if this project is to happen sooner, rather than later; volinteers for making the code happen are needed. otherwise, its where and when i get the time myself to do anything further with it.

volinteers ? :)
