Hello,
I’m not sure if this was already discussed so I apology if yes. Idea would be to add a more vintage approach to the overall phatty sound, I understand goal was to improve tuning stability to certain extend…
As on dsi instruments if I’m not wrong where it s possible to define drift, maybe on the sub 37/phatty it might be useful ?
Thank you for sharing your thoughts !
My good old 1979 Minimoog has so little drift once it is warmed up for 10 minutes, that I don’t miss such instability at all. Also my Prodigy is very good in staying at its pitch. I don’t see and hear a need for this. And if you like to get such instability for special usage, how about feeding in a little wee bit of random drawn pitchbend data from your MIDI software?
Thank you and sorry for my delay 
Yeah a potential good idea, what’ve tried to explain is related to statements about sub phatty being too perfect compared to slim phatty which sounds more alive. There is s topic about that I see now
To be followed
Give it a super slow LFO waveform, peaking at about .5V, into the pitch input. Not enough drift? Crank it to a maximum of 1V. Make sure it’s a triangle waveform, maybe at a frequency of one cycle every two minutes, or something. 
Thank you for this clever suggestion! If they can add it in the next sub 37 software I would be very happy as well (to avoid to use an lfo for the patch).
In case Amos is reading this board and want to comment, feel free ! 
All the best
If you don’t want to “waste” an LFO - the CP-251 is always an option, or even an expression pedal gently modulating the pitch CV input.
Yes, that too…expression pedals are totally underrated. Also, the fine tune knob, but that won’t throw the pitch off enough for Minimoog type drift.
The latest firmware (1.1) for the Sub 37 will have the ability to add drift to the oscillators.
Good to know -
was it mentioned somewhere ? I haven’t seen it confirmed at the sonic state video
Yeh if this is true that’s awesome. Likewise I haven’t seen this mentioned yet either. Though Where did you find this bro?
part of the problem that so many people seem to always miss is that the special “alive” sound of a synth is not just the drift in the oscillator frequency, yes it is this but its also the combination of it and the “drift” in the Filter/Amp envelope attack and release when its pure analog VCF and VCA. the slight randomness of the attack time just makes every keypress/note sound slightly different and …unique. less static. less “sterile”.
Play a bunch of 16th notes like a machine gun rapid-fire on a Minimoog, and then on the Sub37 and listen to the bite of the attack youll see what i mean. not only does the actual note start time “drift” slightly , but the attack time changes ever so slightly as well. Some notes take slightly longer for the filter to “wow” up…etc. its all very subtle but the ear picks it up for sure.
i think the Sub37’s digital envelopes could really do with some “randomness” as well. this could easily be implemented in the firmware. just an idea Amos…

It is in beta versions of the next Sub 37 firmware release. The parameter is called “VARIANCE”.
^this
Yeah, the variance feature is pretty awesome. It’s symmetrical so if Osc1 is +.02c then Osc2 is -.02c
It really does fatten up the sound. Each time a key is pressed new random offset values are generated.
a sound demo would be good (even I imagine you are not allowed to do so) too bad it was not shown at sonic state demo.
Amos please 
difficult to wait …
Damn this is some seriously awesome news!
Don’t have to worry to much about variance in envelopes if your playing sustained notes. Would be another cool thing though, Although personally Osc drift would make a lot bigger difference to me when designing sounds. I often find myself making things which a slightly wonky!!
Is this something that can be added to the sub phatty? I didn’t need paraphony or a sequencer but would like some “variance” sometimes.
Also it would be great if it ever so slightly varied the waveshape.
for now I’ll keep recording a pass of very slight osc2 pitch knob movement to the daw.
Also, hi. First post regarding my first Moog.
I simply forgot to mention the Variance parameter in the Sonic State Sub 37 video… to my regret!
I didn’t realize there was so much interest in this feature, really… but some folks who are testing it seem to like it a lot.
Regarding the Sub Phatty, my schedule is difficult the next few months but I will do what I can to make a small Sub Phatty update.
The features I’d like to add are poly-chain and pitch variance.
Just a small note, the reason I’m calling it Variance and not Drift, specifically, is that it isn’t a “drift” like adding a random LFO… it’s a random detuning that only changes with each new note. This means a long held note will maintain its pitch. But if you repeat the same note, it might be a few cents different each time. This seems to be a good way to do it, in practice.
Sometimes I wonder if these other differences are more about the slight random detuning of the oscillators that makes it seem like the attacks and filter blooms are different. The random relationship between the two oscillators means that they are randomly in different phases each time you trigger a note.
A perfect example of this can be heard by simply engaging the KB RESET button on a Sub 37, the HARD SYNC OSC 2 hidden parameter on the Sub Phatty, and the NOTE SYNC MIDI-accessable parameter on the Minitaur.
When that feature is selected, it always sounds like the attacks are much stronger, even though you’ve actually done nothing to either the Filter or Amplifier ADSR’s Attack Time.
hi Demon,
i agree with you, i think theres a LOT of things that seem to make a sonic difference. there are so many small interactions and variations that just convince the ear that “this is real analog”, some of the things i believe are still not completely understood yet.
i personally think that making the envelopes digitally controlled takes away one of the many “sloppy” variables that the ear listens for in analog. But i think if a “slop” factor was possibly to be added to the digital envelopes , just to add that little bit of randomness, it would certainly go a long way for the Sub 37.
i guess it would take enough people to ask for it, for Amos to consider implementing it? maybe 50% of people won’t consciously hear a difference. So its not a big bonus for the amount of programming, i guess. But i bet at least 75% will UNCONSCIOUSLY feel it…
