just wanted to thank s.pedaal for putting the DS2 service manual online.
my ds2 is in perfect condition again, when I got it, almost everything
was dead, except for the envelope generators...
besides this, I midified it (polyphonic, yes!) using a doepfer
midi-gate interface and a lot of CMOS-switches to emulate the keyboard.
an awful amout of work but well worth it!
cheers,
