[sdiy] roland chord/organ s09 release issue

[Jean Bender]

Thanks for advices !
For the transistor, i didn't look at its number part.. It was one
soldered on the intermediate board, i found it following the straps
whose came from the enveloppe circuit. This transistor was on the edge
of this circuit board, and partly desoldered. So when there were no
contacts, release mod was always "open"..
I can't find schematics, sorry.. Hope it's clear.
Best
J.
