[sdiy] Where should I look for the problem ?

[gilwein at walla.co.il]

Hi all !

I've managed to fix most of the problems on my Kawai SX-210,
still one has persisted - for every 8th note that is assigned,
the VCF EG won't work. That means that the Attack and Decay 
(and I guess also the the Sustain and Release) won't respond for any
8th note that is assigned.

Which path should I look for ? I thought I5 or I6 may be wrong...

here are the schematics nad block diagram for the microcomputer PCB, Thanks in advance !
