My specimen has spent too much time in a hot, humid garage. With that in mind, I'm not expecting much from it, but wanted to pick someone's more knowledgable brain before resorting to declaring it deceased.

What happens to a Moog Source's memory when its battery has died? Does it revert to the presets or is it completely blanked? If it completely blanks, does that make the synthesizer useless?

Finally, if all the membrane buttons are shot, should I still be hearing a preset sound if I press the keyboard after I let the instrument warm up?

Any info is useful, thanks in advance.

If the battery goes dead, most of the settings go to zero.

to test the membrane, press a function, (Osc. 1 level for example)
and give the data wheel a spin.
the smaller display should change.

If there is no activity, it could be a badd membrane
or a digital control problem.

Let us know what you find.

Hi Chunter,

If it was stored in a humid location for a long time, you may have a rust problem too? Also, I think heat could cause the keyboard bushings to crack, though that's probably more likely to occur in dryer conditions.

I'm not sure if the parameter values actually go to zero when the battery dies. They may just become random. If your Source has no sounds or sounds which don't make musical sense (and are therefore probably not the ones intentionally programmed into it) then it's likely the battery's dead.

Like Electrojoe said, just press all the buttons on the panel. If the parameter values are all set to zero, change each of them using the wheel so they're different. Try switching back and forth between different parameters/values. If you press buttons which don't change displayed values then you've probably got a bad membrane panel, which is a serious problem as far as Source problems go.

Please email me privately if you need more information or give up on it. I'm always interested in buying broken or parts synths. Working synths too.

I hope this has helped. Good luck!

When turned on, the program LED shows '1', the edit LED lights, the LED over Octave +1 lights, and the mod rate LED lights (solid, not blinking like I think it ought to) and, leading me to believe all the membrane switches are shot, none of them cause anything to appear in the LED counter by the data wheel.

I appreciate the help, I posted to make sure there would be a reason to start replacing the membrane switches in some way before I buy a ton of pushbuttons only to learn that a tanked memory can't be fixed.

Any more insights, advice, pointers, or otherwise links to information on how a Moog Source ought to behave (as well as what it does when it's broken) is much appreciated, and thank you all in advance.

PS- The advice so far is leading me towards getting a switch or two working to see if I can get a number to light up by the data wheel.

I also have a Source that just recently decided to get a mind of its own - not crazy Source syndrome but for some reason will just not make any sound for days/months then will all of a sudden work perfectly again for a few months. I took it to an electronics store that works with synths and he couldn't figure it out although this was the first Source he had ever worked on.
