Hey all! To fill you in; I've had a long interest in electronic music that utilises vintage synthesizers (Boards of Canada, etc.) but I've never had any of my own due to budgeting constraints, and relative rarity where I live (Australia).
However, by a stroke of good luck, a family member long term lent me their Moog Rogue which they've been the original owner of since new. I played the synth for a couple of hours and everything worked fine EXCEPT for one wave shape setting in the modulation which was described to me as a "randomized arpeggiator."
Anyway, later that night, I got on a short plane ride (Sydney to Brisbane) with the synth boxed up in the original styrofoam packaging, and I stowed it securely in overhead with nothing on top of it, later that night I unpacked it but I didn't get round to playing it.
All this brings me to this morning, when I was eager to start playing it again, so I got a pair of headphones and a quarter inch adapter. I wasn't sure about the inputs and outputs, so I tried output first but there was no sound, not even a hum, so I moved on to input. The input immediately had a quiet synth drone, which I couldn't alter the volume of, and it persisted whether I had the auto-trigger on or not. I could change the pitch using the keys and the corresponding knobs, but even with the attack and delay right down low it wouldn't go away! Alot of the modulation affects seemed to have minimal/no effect on the sound as well...
At first I thought I needed to run it through a pre-amp, but the volume seems to be stuck at this low point, and externally there are no signs of damage, so I'm fairly sure the problem is due to my error, am I doing something wrong with the headphones and inputs/outputs?
Anyway, sorry to bother all of you, but I'd really like to get to the bottom of this!
