VCO 1 Constant Modulation

Post by jessenator » Sat Jan 26, 2013 5:29 pm

Hello all,

Just got my NIB Voyager Old School and I'm super excited it's finally here- and that I actually found one.

Ran into a problem. I've checked the modulation sources, the 3–1 FM switch, but VCO 3 is modulating the frequency of VCO 1 constantly- the switch is off, and there's no mod sources routed to the pitch and it's just VCO 1.

Is this something that anyone's had an issue with and knows a good quick fix, or is this a "good thing it's new in box and use that warranty" situation?

I'd rather not have to send it, since I'm in the intermountain west and shipping's a beast these days.

Thanks for any info.

So it also additionally appears, under the scrutiny of my tank-like oscilloscope, that the triangle waves of VCO 2 & 3 are not the same shape, the sawtooth waves are not the same amplitude through the mixer (square is OK)

OK SO I REALLY JUST NEED TO KNOW- is this normal (i.e. within the margin of error for the production line), am I nitpicking, and should I just shut up and be glad I have a moog and play it? Or is this something I need to have concern over? Videos forthcoming
