I had my pitch bender fail and it wasn't possible to clean or restore. It's a special custom made pot with all its carbon contact range printed in a very small portion of the track. I'm not certain if there's anything special about the mod wheel in your case though. I tried emailing moog and was wai...

Yes its definitely the switch itself. One of my switches did exactly this and I desoldered the switch and found a small piece of plastic inside that holds a metal contact plate broke. It was fixable by superglue in my case. But replacement is only a job for someone skilled at repairs. I would recomm...

Looking at the schematics, the jack is a TRS but it appears that the RING of the jack is only a "Foot Pedal Detection" sensor. So basically this senses if a TS cable is plugged in when the sleeve/ground touches the ring it pulls the 4503 hex buffer low on the digital board so it knows some...

Divide down synths use release capacitors in the divider circuitry. Sometimes these can be caps that are prone to failure such as tantalum or electrolytic caps. This is where I'd look first, identify the exact notes in the circuit and then check the capacitors.

are you drawing the notes with 0 velocity?

Try doing a reset of global settings also.

you can always check the solder under the connectors, I remember seeing an opus once which was missing strings because of a cold solder there. Otherwise, as usual it's a difficult to troubleshoot anything over the internet. Always best to take it to someone who can look at it if you are stuck.

Greetings, with such little info out there on the technical side of the moog guitar I thought I’d share something that’s recently solved an issue I was experiencing. After bringing my E1 in for a setup, I noticed there was almost a fuzz sound in some of my strings. After getting in touch with moog s...

I had my frets plek'd, not once, but twice since I wasn't happy with the results. Either the plek operator had no clue what he was doing or something is up with my E1... it buzzes like crazy from the frets. Even after the second time it still buzzed bad. I almost wonder if I should just have the dam...

Wait, the 4051's are supposed to be -15v? Are you sure? If you're reading -15v on all 4051's it sounds like S131 is plugged in backwards....

I remember working on a MM once that had a dead -15 rail, and the only thing it affected was the voices. The digital side all worked..

It would be nice to have a release stage added to the aftertouch. The problem with aftertouch is always that key pressure off is always too abrupt, would be nice to have a smoothing feature so the signal fades back to 0 AT.

Here's one for me: Improved random name generator. Add 3 new keys, random noun, random verb, random adjective. Make them stack so you can build a name in pieces instead of sitting there for hours hitting the random button and settling on something ridiculous like "adhesive bunghole". Yep, ...

POLYPHONY SECTION BUGS POLY COUNT and STEALING MODEs are very bugged. When setting Poly Count to an arbitrary number and the sound is saved, ie. 4 voices, changing the sound back to "AVAILABLE VOICES" will stay at the last amount of voices saved into the patch, ie. 4. "NO STEALING&quo...

I see... tried googling it but couldn't find anything about it but a search here with some digging I found someone else reporting it. Hard to believe they haven't done much about it, at this point I doubt they'd ever fix it since it's probably too old to bother and not many seem to care. Oh well, st...

Being inspired by the MG-1's synth architecture of simultaneous lead synth with poly section through filter, I thought I'd try something similar on my sub 37... sending a poly synth into the input of the 37 and set both oscillators to high note priority to always have that lead type sound over polyp...

replaced the 4558 and de-soldered and re-soldered all the new MM5823 and still no High A, the middle and low A are warble/fuzz notes in Polyphony, and in Mono mode i get that notes only play when others are held down. time to try the U8 741 and time to buy a multimeter :) Did you check the traces o...
