Vintage Synth Repair

You are correct, sir, my bad. I thought 770 was a type-o for 707 as
you suspected. As for the mysterious mouth controller, I believe it
could be related to the Korg Pepe [MIDI controller] which was created
solely for Josef Zawinul in the 80's---rumor has it that Joe wanted a
MIDI version of his CV breath controller.  I suppose if you can get
some schematics/service manual [good luck finding one] of the 770 or
if you feel adventurous with a multimeter, a rudimentary CV
mouth/breath controller can be built.  I did find one service manual
at this site:

But I was not able to open it---it could have been created with an
older version of Acrobat; perhaps you might have better luck with it.
