i can get sound out of each OSC output, but nothing that i do on the keyboard effects pitch. only on with tip - off without...
i cannot seem to route audio to VCF or anywhere for that matter.. i must be doing it wrong..
Don't mean to state the bleeding obvious but you do realise you need to patch a lead from the output of the oscillator to the input of the filter to do that don't you?

Pitch: patch from a RED banana on the keyboard to one of the BLACK bananas on the VCO. Use a voltmeter to confirm the RED output is generating voltage changes.

Filter: patch 1/8" from the VCO saw to the 1/8" INPUT on the VCF, then 1/8" outputs of VCF to your amplifier.

Alternative: buy me a plane ticket, book me a motel room and I'll fly out and help you check it out =D>
I listened to Hatfield and the North at Rainbow. They were very wonderful and they made my heart a prisoner.

Well...obviously it's worth whatever you can get someone who wants it to pay. There may be someone out there who would pay $500-$1000, but I think that would be based more on sentimental value than an objective functional/quality comparison with today's available alternatives. The PAIA modules did the job but they were designed to be fairly low-cost for the day (a 4700-J was my first synth back in high school in 1978 -- the kit went for $550, a lot of money for a high-school student at the time but still way less than an ARP or Moog)...and that low-price design point does show through at times. The power supplies are not regulated at all and there's a fair amount of ripple on the PS rails, thus you will typically hear some amount of 60 Hz hum in the audio. The VCOs drift somewhat. Low-price op amps in the audio chain add some hash noise to the audio. And so on. It is a great synth to learn on though and its price point was somewhat of a miracle at the time they were sold. Enjoy!
