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.)sztakics_isti wrote:Hi. I have my Sub 37 only for 7 days.

I CAN HEAR THAT BUZZ (HUM) SOUND. As I read the forgoing topics, it seems to be a common problem for Moog Sub 37 units.
I tried to make a simple sine wave like sound using the triangle waveform and I used the following setttings:
OCS 1 - 2' triangle max volume on mixer section
OSC 2 - 2' triangle max volume on mixer section
Sub osc - 0
Noise - 0
Feedbck - 0
Cut off Filter - 320 Hz --> 80 Hz
Reso - 0
Multidrive 0
Slope 24 db
EG amount and KB amount 0
Filter ADSR - 10, 0, 10, 10
Amp ADSR - 0, 0, 10, 10
No LFO 1 & 2
and the HUM appeared. I did't noticed this problem before, when I was surfing through the factory presets.
And yes, the hum is present between the triangle and square waveforms. (12 o'clock position on the wave shape button).
I tried the same settings on a Moog SubPhatty and the hum is not present. The sound of the Sub Phatty is much clearer.
I registered my Moog on Moogmusic and described the problem yesterday (friday the 26 th of September). No answer until now. I hope I will get one monday.
Sadly that hum is bothering me, and I am disappointed becouse I was waiting for this synth so much. However I don't want to send it back, I would keep it and I will filter the hum out of my recordings using an EQ.
I hope that Moog will correct this issue with the next firmware update. ... and I hope the Moog will include a feature that shows the exact bpm rate on the LCD screen, as it was on the Little Phatty.
Please check my attached files.
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.
