Re: Memorymoog "DEAD OSC" on all voice cards OSC3
Let me start by saying there’s nothing to be embarrassed about. Your Memorymoog is totally mind f’ing with you and you need to kick it in the balls. Fear not, it has plenty to spare :D . The service manual gives a pretty good explanation of the s&h function. What’s you’ve done is a fairly sizabl...

Re: Memorymoog "DEAD OSC" on all voice cards OSC3
Good progress! But it still seems like the S12/S54 ribbon cable signals are getting screwed up. Since you’re doing a refurb It’s definitely worth making new ribbon cables. Always nice to have a spare set so even if it doesn’t fix this problem its not wasted effort. Autotune giving 0 tuned and yet C7...

Re: D reissue "drone" options
Send a midi note on message without a midi note off message. I knew that one day those old versions of various software would be valuable.

Re: Memorymoog "DEAD OSC" on all voice cards OSC3
My blobs will put your’s to shame. Good you spotted it but I wouldn’t worry about it anymore-shit happens. But I came to this when I was measuring voltages on the DMUX again earlier and found that at pin 10 of U3 (7417) which by the schematic looks to go back toward the OSC3 amount, I was reading 5v...

Re: Memorymoog "DEAD OSC" on all voice cards OSC3
Trying to avoid some more misunderstandings so please clarify the following: -OSC3 low on all VCs (I assume you mean low output level?) .; turning up OSC3 mixer section produces a squeal which leads into the note. Sometimes the OSC3 sounds like it's dying a slow death. Autotune will read the hex dat...

Re: Memorymoog "DEAD OSC" on all voice cards OSC3
Oh man, I wish we started with those videos. I thought Osc 3 had no sound or very limited output. This is a Osc 3 pitch/ frequency issue which does point to a voltage input common to all VCs. Now we’re back to the CA board.
I would look at the OSC 3 Sum signal coming into any VC as you play a note.

Re: Memorymoog "DEAD OSC" on all voice cards OSC3
Ah...I believe removing the cards is different than just removing those ribbon cables. Only I don’t recall what it is. There maybe something funny with the power distribution to the boards or routing the audio outputs back to the CA board.
Are you working with a scope?

Re: Memorymoog "DEAD OSC" on all voice cards OSC3
I assume you mean removing S54. Yes that should tell you if the problem is at the signal source or if one of the VCs is pulling the Osc 3 amount down. Or maybe something else altogether. You can also defeat all but the one voice that’s still connected using C4.

Re: Memorymoog "DEAD OSC" on all voice cards OSC3
Excellent. You’ll figure this out, of that I’m certain.
Regarding the 3 parallel socket locations for S54 I can only guess that when they built the DMUX they had a different routing scheme in mind for those signals.

Re: Memorymoog "DEAD OSC" on all voice cards OSC3
S56? Did you mean S54? S54 carries the 3 Osc amounts so I can see this affecting the Osc level/volume.
Word of caution- lifting those connectors while power is on and making contact is extremely risky. I strongly recommend you not do this.

Re: Memorymoog "DEAD OSC" on all voice cards OSC3
Scratch what I wrote previously. If there’s a problem with the control signal for Osc 3 Amount it could affect the C7 read out. The firmware enables and sets each Osc amount to max (I believe) to ensure a proper read out. The Osc Amount doesn’t come from the CA board. The CA board sums all of the mo...

Re: Moog Matriarch: Gate Out using Multitrigger V 1.2.3
I'm sorry but I believe you're mistaken. This is a paraphonic with one gate signal only; multi-trigger affects the envelope re-triggering, not the gate. If it worked the way you wanted wouldn't the gate be interrupted each time you play a new note causing the held note to glitch? This is not a bug. ...

Re: Memorymoog "DEAD OSC" on all voice cards OSC3
Hi Mike- Now you've gone and done it - upsetting the memorymoog Gods, shame on you! :oops: I'm suspicious that the other osc are really being updated. Maybe start by clearing out the auto tune values (press C5 iirc). When you hit C7 are you seeing the osc 1 and 2 values change? Maybe tweek a trimmer...

Re: Matriarch Firmware v 1.1.0 Update Issue
If you're using Midi Ox after you send the first file (Invalidate) you have to close out and re-open Midi Ox. This was the only way I found to re-establish communication with the Matriarch. Just selecting the ports again didn't do it and I had the same problem you guys described.
