No, I didn’t get the keyboard. I’m hoping to be able to use the one I have with my dot com system. I’m told that, with the proper S trig cables, it will work. If it doesn’t, then I’ll probably get the 953. That will be an ergonomic issue for my space.

I believe your going to need the Moog Voltage to Switch Trigger Cable .
I don't think you can trigger the VCA with out them not sure .

Yeah, that’s the ones I have.

Took delivery of the Model 15 today. Everything seems to work fine. However, though the s-trig cables work, the 921s are not tracking the dot com keyboard accurately. As you play up the scale, the tones become progressively flatter. After a couple of octaves, the error is almost a semi-tone. Anyone have any ideas what the problem/fix might be? Thanks.

check the dotcom output as a voltage... if you are not getting 1V per Octave in the keyboard output CV, then the 921s are tracking an incorrect reference perfectly.

if the keyboard is giving a good V/Oct output, then speak to Moog on Osc calibration.

Good luck!

Thank you for the suggestion. I did check the voltages coming from the .com kybd. They are within tolerances. I will continue to investigate. Very puzzling though.

Sorry for the daft suggestion, but are you having the issue in the context of the voice or from oscillator's output itself? When I read the sentence, I wondered if you were hearing the filter dulling the tone at its cutoff. Otherwise, seems like vco calibration time. :waah:

One other thing to try; the 921 (integrated OSC) to see if it plays in tune by itself. If it's off by the same margin, then all of your OSCs are probably improperly calibrated or (most likely), it's the keyboard voltage drooping on you.

Also, have you tried the left 921b versus the right 921b? When tuned together at a lower bass note, do they track identically up the scale?

One other thing to try is to set the 921 into LFO mode and use it to drive the ~1-2 octaves of voltage, the pair of 921b's. With the 921a sitting stagnant at a base frequency voltage, a slow ramping sine wave as offset into each 921b should also scale similarly without detune.

Point is, you need to determine if the 921a is out of tune or if just one of the 921b's are out or both.

If a recalibrate is necessary, it's a "shame on Moog" moment. I had a few gripes about my Model 15 delivery but that was years ago (my serial number is in the 20-30 range).

EDIT: Also, you say "dot com" keyboard controller. Which is it? The old model or the newer Midi only version and if so, what are you using for a Midi->CV controller?

Wow, EMwhite, that was a very comprehensive, and much appreciated, answer. I have tried most all those things and finally realized the problem. It was a stupid thing on my part. Definitely not on Moog. The cable I was using for pitch control wasn’t long enough, so I had an extension on it. That was the problem. I still don’t know why, but when I tried a longer cable, problem solved! I’m sorry I troubled you, and Gerhard, and James from .com. You have all been very helpful and I appreciate it greatly. Now I must go stand in the corner and feel foolish for awhile.

I'm glad you got things sorted out! :tu: Don't feel too bad, I've lost count of the times I assumed a module was defective only to realize later the problem was just with something I was or wasn't doing. :doh: :hihi:

So, why would a particular cable or cable extension cause poor tracking? I would guess things like poor/dirty contacts or very thin and/or failing wire causing excessive resistance? Or maybe the cable design had a high level of capacitance, although I'm totally guessing on that one. :hmm:

Nope. Don’t need it. The .com kybd is working for me. BTW, the 15 is awesome. I’d buy another one

Agree! The Model 15 is awesome. The one thing I do wish I had is a 904b High Pass Filter. Right now the only way to get one would be to buy a System 35 or IIIp. I so wish Moog would consider selling certain modules individually. Not so likely, sure...but I can dream!

JLR. The cables were good quality .com cables. I’m not an EE or anything, but i’m Guessing it was the double female coupler somehow causing a voltage drop. Not really sure, but glad I got it working. The combination of the .com system and the 15 is making me smile. I can’t say enough about the Moog. I have an old Mini which I really love, but the 15 is something else. I hope to take delivery of a couple of 901 banks from SW next month. Things are getting interesting. BTW, i’ve Listened to some of your music and I am impressed.

Have you tried the Moon S175? I have a couple and use one as HP and the other as LP. Not saying it’s equal to the 904s, but they’re pretty good.

No I haven't. The Model 15 is the only MU I have at the moment. It was the Aion eurorack clones that led me to the Model 15. The only thing left of the Aion stuff is the 904b because I like it so much! But now I'd really like to have an authentic version.

If you don't need to have high pass at the same time as low pass you can use the low pass as high pass by mixing its output with the original signal. It's not perfect and you need to be careful tweaking the mix levels, you'll find it out though.

Sorry about the rotated pic, just can't get it right, hope it helps with patching

Thanks, however I already tried that approach. It's OK in a pinch, but I would prefer to have the flexibility of access to low and high pass independently. It also doesn't quite give the same sonic result.

Here is a multitrack using ALL sounds from the Moog Model 15 -reissue.
Pretty extensive multitracking I can say! Modular multitracking taken to the next level kind of...
Anyways, my findings...VERY impressive sound. It has this magic edge in the mids only found in vintage ARP 2600s and maybe Moog Modular vintage, I have noot been playing a vintage Moog modular yet.

I built my own... managed to keep an attenuator though... 8-)

This is really great.... Has me taking my hat off to the Moog Reissue team as everyone seems to have only good things to say about it.

Right on!! :minimoog:
