First off, if you have the OSC mixers on Max volume, you are overdriving the Oscillators. You need to set the OSC at below 5 (this is by design.)
Second, though I still don’t hear the drone or hum, when I have an OSC set to 2’ and play the high “G” note while sweeping the OSC waveform knob from triangle to square, I do hear a scratchy sound, but only while sweeping the knob (also happens when sweeping the OSC volume knob.)
With that being said though, even though I apologized to gencomprodukts for being so hard on him, my main point all along was that, anyone who claims this is bad enough to make the Sub 37 “unmusical” and to then send it back, is really missing out (to put it kindly.) Once you have an actual sound programmed, i.e., both Oscillators going with Filter, Modulation, etc., and then have that sound sitting in a mix of an actual song, I bet you all the money in the world you will not hear that “hum”, or at least, it won’t be heard enough to make it “unmusical.”
Again, while a very small handful of people complain and spread FUD about this, many others are actually, happily making music with the Sub 37… and in any case, Moog said they are fixing it in the next Firmware update, so it’s all a moot point anyway.
Yes. Despite that HUM that appears not only on maximal volume of the OSC in the mixer seections, but also on lower (position 5) settings. I AM A HAPPY USER OF THE SUB 37 .
I wrote to Moog Support about the hum, and I told them about some other interesting, but missing features of the Sub 37. I wrote them that it would be nice if the LCD screen could indicate the actual bpm of the ARP or SEQ, and the patch select knobs could be used to control the steps of the sequencer. (e.g. to skip, or introduce some steps while the seq is running, or to set the last step in the seq row.)
Today I got the following answer:
All these things are coming! #1 is already fixed, we have a small firmware update planned for ASAP which fixes the 80Hz hum. #2 and #3 are coming also, probably in the following firmware update after the one that is currently in the works.
Cheers,
Amos
So … I am waiting … and making happily music. BUT as gencomprodukts said, a pro gear should’t have such an issue.
I agree, but some people here, and on other forums, were being a bit dramatic about the “hum” issue and were actually scaring people away from this synth. As I said before, to me at least, it was never bad enough to claim that is was completely unusable and thus be forced to return it.
As for those other suggestions, those are really great suggestions and it will be nice to dial in BPM more accurately via the LCD screen.
I’ve got an update for test and it’s very much better now with the “buzzing sound”. It’s not 100% eliminated, but what left is not as bassy as before and much quiter. For me it’s o.k. to live with.
@gencomprodukts: have you had a chance to try this new fw version? since you were the ‘one with the golden ears’ who first identified and reported this issue, i’d love to hear your opinion about the update. on rufus’s screenshots, the improvement doesn’t look terribly impressive - but of course what counts is what it sounds like, not what it looks like in a spectro-analysis…
Hi Bartleby,
I’ve finaly had the chance to test the “buzzing sound” firmware update and i can only repeat what the other members (Hicome & Rufus) reported: it’s not 100% eliminated, just reduced but it’s much better.
I can live with it now but you must know that it’s still there even though much reduced.

Is it possible to downgrade firmware? Or is it only possible to change to a newer version?
The hum seems to be getting worse or becoming even more noticeable. When creating softer sounds, it’s impossible to avoid it. Is this something that will be eliminated conpletely at some point or is it only able to be reduced in intensity? I really hope Amos and the rest of the crew can destroy this bug! Go Moog Go!
