Discussion about the Korg PolySix synthesizer

Hi all,


i know thislist is not for the EX-8000, but i could not find any 
forums/user groups about the DW/EX-8000.

The Problem is, that only two Sounds came out while pressing eight 
times a Key on the Keyboard.

The Oscillators themself work all correctly. Now, i´ve seen below the 
OpAmps 16 Capacitors (yellow/black, 22 Microfarad), which are mostly 
connectged to thosecustom-KORG 2260 ADA-Chips . When i make a bridge 
on the connectors of one of these Capacitors, i´ll get a sound, but i 
can´t change the cutoff-frequency, that means, that the sound which 
passes the 2260 coming from the Opamp, is to 100% non-filtered. 
Changing those Capacitors has also no effect, the problm is still the 
same. 

On the 2260 ADAs are all Voltages correct, except with the 
difference, that the four capacitors on the right side of the not-
working chips shows no Voltage when pressing a key.

Now is my question: Is there any chip which triggers the 2260 or does 
anyone knows that problem?

Greetings + thank you

Stef
