[sdiy] roland chord/organ s09 release issue

[Jean Bender]

hi list !
i've just got à beautiful roland chord/organ and it world great... but
sometimes, release stop working. it acts as if it's full open, and you have
To shut down the synth To get it normal again.
its absolutely not foreseeable...
ive open the synth, all parts look ok.

i guess i have some recaping to do ? but where ?
would somebody have an idea for fixing that ?

thanks.
best
J.
