I could had placed 3 voices in one larger board instead of 3 separated boards, sharing cabling for power and a control signals,
Awesome project

Tip: avoid for your own purpose large pcb's,its all fine,cut costs etc,but large boards that heats up = more distension of the board = higher risk to cracks in long traces (after 30y cooling/heating).

If you wanna do large boards draw long traces ' repeated sawtooth or angled 'staircase' like ,but with no right angles of course) and use thicker PC material.

Starting to look better in the new chassis. Cannot believe I forgot to purchase the spacers to mount the PCBs! Crap.

I will try a different arrangement for the boards: in the original Memorymoog the voice cards are mounted in hinged spacers to give access to the trimpots for calibration. However, there is no need to lift the boards in my prototype because all trimpots are mounted along the front and back edges of the boards. Instead, think it will be easier to calibrate if I assemble the Contour/Glide at the top because it is pretty hard to reach for its trimpots and measurement points right now, under the voice cards. Another advantage is that now the slots to access VCO trimpots will be closer to the bottom of the rear panel, and will not interfere with the big "MEMORYMOOG" at the back.

Cheers!

I don't know why, but this is triggering my DIY-lust in a way that even Acme's Jupiter clone does not.

Oh Boy! What a great project. Kudos.

Some of you know that I was a Moog repair center here in NJ in those days, and I used to dread getting a MM for repair. The customer would say something about tuning or just now working, or partially working.

Of course when I opened it up, everything was fine. Then when I closed it, it stopped again. (Or something the direct opposite of that.) They were servicing nightmares IMHO. Bad connectors, intermittent flex cables - you name it.

I'm really glad to see the honor of the original design philosophy in a modern updated form. Sincere congrats!

I am no electronics expert, just a hobbyist, and it is a VERY complex circuit. Lots of room for error!
This sentence prooves that you are delicate and humble person.
But .... for hobbyist ... this is definitely very tough project.
You're surely near pro level.
Just a "Monkey see, monkey do" method doesn't provide such a phenomenal output.
Great job !
It's unbelievebale ;)))
:sb: :sb: :sb:


It's funny, because I also transfered the whole service manual to Kicad, and planned to do a clone.
But not so soon, right now there's no gas to fund such an ambitious project like this.
I have a plan to build clones of some of my favorite vintage synths.
Sounds crazy, but ... it's fun and ... taking to a count the cost of original ones, it seems very reasonable.
When I had some question regarding DMUX board connector I decided to google the hi res picture of DMUX board
and seems like I've found your blog.

https://memorymoogclone.home.blog/

And realized, that ... I'm not the only one, in a good sense )

My main question is ... shall your project become open source for other DIYers ?

This topic is a great source of inspiration and motivation.
I'm sure your MM will perform outstanding and definitely won't suffer from original issues that much.
As far as I understood you have no plan yet to MIDIfy your unit ?
DO NOT go the path of plus version... Sluggish 16th note perfomance guaranteed.
I had a chance to rent a PLUS version for a studio session once, it was awful ;(
The only paths are LAMM or Kenton. Expensive, but worth it I guess.

Really nice job!
Having the trim pots accessible without having to open the case is a great idea, this should allow for much more accurate calibrations, and make it easier to maintain them going forward. :yay:

Speaking as someone who professionally repaired vintage polysynths, please relocate the battery away from any pcb. They're ticking time bombs and if/when they leak, unleash a cancer that eats traces on the pcb - even after replacing and cleaning (eg. Polysix).

In any case, fabulous work!

Plan is to make all files available. Thing is, right now it is a bit messy: sometimes I make a change in some board and do not annotate it back in the schematics/board layout; or, I make some annotation in the actual printed version of the schematics and do not updated the .PDF file with the schematics, and vice versa. So if I make the files available, I cannot make 100% sure they are error free. Of couse, if errors are found I can update the files later. Probably I will create a shared Google Drive folder with the files, have not decided yet.

Think my best option is to get a Kenton MIDI kit, indeed the Plus board looked pretty bad and I decided not to clone that.

As far as I can see, this prototype is more stable than the Memorymoog I used to have many years ago. However, that unit did not have the autotune update, which is included in my project.

Anyway, I should receive a batch of board spacers early next week, so I will be able to assemble the electronics in the final configuration, with correct cable lengths, etc. So far I assembled the (still unpainted) front metal plate and it is starting to look Memorymoog-ish! The pitch and mod wheels still cannot be attached in place because I still have to order the brackets to hold the potentiometers in the correct positions.

Never mind the wood supports under the panel boards; they are temporary, I only mounted those because I was running out of real estate in my desk! Needed the room for the calibrations.

Cheers!

Don't sweat it mate, apparently Moog does their mockups the same way. :tu:

I was planning to do the same thing to my Memorymoog back in the day, placing them at the slots available for the Plus expansion in the rear panel. I gave up when I realized it would require some 126 wires to connect the trimpot terminals to the voice cards...

Glad to help out. :)

I have a very ~visual~ sense of humor which (most times) translates very poorly over typed words or phone telecons ... I sortof go into little character voices at times, facial expressions and body language are all a part of the gag-ery. Boil all of that down to just the words and it's pretty crappy, and can be offensive sometimes simply because I'm not in person adding all of the visual/vocal nuances. So I'm glad ~this one time~ it worked. Hell, it even makes me laugh! Feel free to do whatever you like with the joke there.

:)
