Subject: [AH] Jupiter-4 tuning (again)


I can't get the VCO's tuned at all. And there are a couple of things bugging

me about how the sound should be set. So, should the keyboard be in the 
Normal mode, or the 1 oct. down mode. I've come closer to getting the VCO's 
tuned when in the 1 oct. down mode, but just can't get 'em right.
And, in the service manual it says that you should tweak the pot #5 while 
the A3 key is pressed, and tweak the pot #6 while A0 is pressed. I haven't 
even come close to the right lissajous figures while doing it this way, so 
I've tweaked pot #5 while pressing A0. Is this right? Or could anyone just 
give me the whole tuning procedure before I'll burst into tears.

Thanks,

/kulma
