Subject: [AH] Jupiter-4 tuning problems.

Hiya all of you who have sometime tuned a jp4 "the way it should be done"
eg. the Service Manual way. Well, hiya all the rest also. Got a problem:

I'm tuning my JP-4 at my school, and got to point 5. on the manual, which
would be the VCO tune&width part. I got the tuning right on all voices, but
didn't get the width right on the last voice (in poly-2 mode). The trimmer
just didn't turn enough. I tried all sorts of funky stuff, re-adjusting the
tune-trimmer, going down one octave, portamento switch, but just didn't get
it right. Any thoughts?
