[sdiy] Topic cem3396

[pHobax at gmx.de]

Hi. I own a elka ek-22 with 6 cem-3396-voices.
A real annoying bug occured, effecting all six voices:
The synth doesn't produce the right waveforms anymore. The saw has a much
less amplitude on all octaves except an the 1st and 2nd.
PW is not real ajustable anymore, it seems to depent on the note played. 
With some ajustments the PW is 0 on c3.
Tri isn't accesable anymore etc....
In addition the seperate voices vary in their volume (not very strong, but
it sux) and the described bugs.
This problem seems not to be located in the chips.
I thoght  the divider or the digital osc could be the reason.
Is there any possibility to replace this unit, and if not is there a good
diy-project using the cem3396??
nice greetings, max.
