[sdiy] Re: Arp Quadra, dead note

[r]

Hi everyone,

I just took some dust off one of my old Arp Quadra.
I had to de-oxide almost all of the left hand keyboard board.....had
to make some jumpers too.
Now everything works fine with the lead synth.
There's  a dead note, the second F from the left, in the poly and
string section. It does not sound at all. In the bass and string bass
mode, this F note only sounds if you hit the key while still holding
down another key (these are mono sections) but its envelope is much
shorter. Hitting the F key alone in bass and string bass mode produce
no sound.

As I see that this F key works perfectly with the lead synth section,
I believe there must be something wrong with the freq dividers of the
instrument.
Anybody else had a problem loke this one?
And.......where is it possible to get the servirce manual for this
synthesizer?.
Thanks.
rikk
