Yes but unfortunatly…only for a short time, you will have the same problems soon, and big troubles with the cut off too!!!
Hi Iscariah,
If that’s true, and the Pitch Bend issue really does come back, it’s still just a firmware issue.
I’ve been using one of my Sub 37s for over a year now and the PB issue only happened right after the last update.
sorry but this is a hardware problem, we had this problem long before upgrading newest firmware.
i was at the repair station store, many moog sub 37 were there with problems too, the store ordered a big quantity of pitch wheel and the same for the cutoff…
this is not serious from Moog to release such a keyboard with so bad issues and with a 30 dollars keyboard made in China…if Bob was still here he wouln t have let that thing happen…
Hi - You’re on to something..
I’ve encountered this issue with several different synths through the years - and for the subphatty and sub37 as well, a problem lies in the wheel’s grip on the potentiometer. When the pitch wheel bounces in place, the pot might not follow all the way, and so the shaft moves a bit each time, not returning to the mid position. This is a construction involving glue, and can be remedied with the same:
- Remove the pitch and mod wheel board
- Remove the little metal bracket that holds the top of the pot to be fixed
- Adjust so that center position fits the mid value of the pot (around 5K from centre to side pins), apply a drop of strong glue where the top of the shaft meets the plastic of the wheel, carefully, so it doesn’t spill into the pot itself and doesn’t leave residue that can cause friction once the bracket is in place again
File under general advice, proceed at own risk etc…
My first issue with the SUB 37 was not being able to update to the new firmware automatically. I tried multiple times using my MAC connecting the USB directly to my iMac. I was able to update it the alternative manual way as provided with the downloaded instructions.
Since updating to the new firmware, my pitch wheel simply does not work no matter which direction I move it. I do not really know how to recalibrate it at this point and am wondering if I’ve gotten a faulty unit. I am a novice when it comes to Synthesizers, but this doesn’t appear to be normal. I’ll continue to try to find answers and keep playing around with it but I think I’m either missing something or I’ve got a faulty unit.
Hi,
I have a brand new Sub 37 on hand that seems to have the pitch wheel issue - it can’t seem to stay in tune. Now I’m not a synth hound I’m just a bass player that dabbles (but is very interested in) synths. I am very disappointed that this issue exists on this machine and not my cheepo volca keys. Right now as it stands the thing has lost all pitch wheel functionality; this happened as I was double checking for the thousandth time as I was writing this. The odd thing is that it seems this has sort of fixed the tuning issue as the tuner I used endlessly prove to myself that something is wrong is now registering correct notes in the initial preset patch. Like I said no pitch wheel functionality - I am on the newest firmware 1.1.0. What do I do now - warranty? I live In Turkey and I did buy it from a reputable seller but I’d like to make sure there isn’t something afoot like some setting I am not aware of. Any help would be greatly appreciated.
Hi guys,
Andy from the Moog Tech Lab here.
If recalibrating the pitch wheel(and other pots) is not permanently correcting the issue, and it does not appear to be an EEPROM issue as described by Amos above, then it is entirely possible that there is a defective or damaged potentiometer in the pitch wheel.
We will be happy to assist you with setting up and RMA to get your synth repaired under warranty, and we apologize for the trouble. We test all of our gear very thoroughly before it leaves our factory, but despite our best efforts at due diligence sometimes the types of situations happen.
Rest assured, Moog will stand behind our products, and we will do our best to make the repair process as quick and hassle free as possible.
Please contact me directly for assistance in setting up the RMA: andy@moogmusic.com or by phone (828) 251-0090 (tech support extensions are 221, 217, and 204).

Can someone advise on how to recalibrate the pitch wheel (and other pots)? I would really like to try the above suggestion before sending off to get repaired.
Thank You.
ok.. seems i have the same issues.. 
I did calibrate a few times (properly!) but it didn’t solve the problem.
But before I send it away for repairs, did the replacement did the trick for anyone? 
(to answer the last post: contact support, they will send you the calibration sysex’s)
Hello. I am having the same pitchwheel calibration issue. Has there been any updates to this?
(I just updated to firmware v1.1.0, and it is still an issue)
Here are a few other things I have noted:
-
The pitch goes farther out of tune the more you increase the range of the pitch wheel. For example, if it’s at -0, there is no detuning. If I set it to -24, it detunes around 6 semitones. The pitch up is not affected by this.
-
I can get it to reset sometimes, but as soon as I bend the pitch wheel down, the same problem returns.
…
Another issue I found is that if I change my Pot Mode in the Global Settings to THRU, then the next time I turn it on, the volume control doesn’t work. (Even if I sweep it across the whole spectrum)
If I set it back to ABS, the volume control works again.
Any updates/answers would be appreciated.
Thank you
… I also just noticed that the BEND UP and BEND DOWN values don’t really work properly.
When BEND UP is set to+24, it only gets to about +19 when you bend the not (when BEND DOWN is at -0)
If BEND DOWN is set to -24, then bending the wheel up results in about a +27 in pitch.
I love the Sub 37, but with this issue I don’t consider it to be properly playable. I would hate to return this for something else.
For the people at Moog: Is this a problem across the board with all Sub 37s, or just a certain batch/supply?
Thank you
We are very sorry to hear you are having this issue. In most cases, it is a simple calibration issue that we can walk you through over the phone. If it is a bad pitch wheel, we can easily send you a replacement that takes 5 minutes to drop in.
Please give us a call on Monday and we will take care of your issue immediately - 828-251-0090

hi Chic, i just wanted to add that i thought i had this problem with my Sub Phatty, but it turned out to be problem in the first patch i used to make sounds from, where the oscillator pitch offset setting was out, and then i continued to make sounds from this one sound and before i knew it i had made 16 sounds and save them all, and then suddenly all the presets had this problem and i thought it was a problem with the Pitch wheel hardware!
Moog walked me through it and i also did the calibration instructions and it all came good.

Hi,
First of all, i want to wish you all a happy new year 
Yesterday i noticed wrong behavior of the pitch wheel on my Sub 37.
MIDI-Monitor gave me these values :
- Low position : 14
- Center : 85
- High position : 127 (value get before reaching the higher position)
As related in this post, a wheel calibration could resolve the problem.
In // of this post, i sent an e-mail to Andy in order to get the sysex file and instructions to perform this calibration.
I recently updated to 1.1.13 firmware version, i don’t know if the issue appeared at this moment.
The editor report these wrong values (as soon as i touch the wheel) :
Hi, I have exactly the same issue and updated to 1.1.13 as soon as I received my Sub37 so like you , do not know if it was present before the firmware update. Patch plays at correct pitch before using pitch bend and then pitch is incorrect after.
my Image grab from editor seems to exact same as yours:
I have contacted support.
Update:
I reckon it is a dodgy pot’!
After going from max to min on the pitch bend wheel afew times the pitch wheel will not pitch down and on the editor the pitch wheel GUI is stuck at the bottom. The pitch is stuck a semitone down after using the pitch wheel. Leading up to this midi monitor was reading inconsistent values for the return to centre.
Have contacted support but I am not optimistic that this can be easily solved with calibration as I have had pitch bend pot issues with various synths in the past and a dodgy pot is a dodgy pot.
Hi Synththeory,
Pot calibration didn’t worked for me
I performed it several times and always get these new values :
- Low : 0 (calibration seems to work because it was 12 before)
- Center : 62
- High : 127 (but reached at 80% of the curse)
I tested the high position calibration with the pitch wheel released to the center and get a good 0 to 127 curse from the lower position to the center.
Tech support are very helpful, RMA is in progress to change the LHC (Left Hand Controller).
Hi gian77, RMA in progress for me too. The pot is definitely faulty or the wheel has completely slipped off the optimal position on the pot shaft due to whatever reason, I am not sure how the wheel position is fixed to the pot shaft in the Sub 37)
Was good to go through the calibration process, even though it did not work. (which I kinda expected)
