This is a dual oscillator. The module is designed as a hybrid digital/analog module; the oscillator frequencies are determined digitally and are therefore quite stable and have a good tracking; the output wavefom itself is created analog.

its like the original 2OSC , so you can modulate pitch using cv1 (which is offset by the pitch knob) , but you if you want to pitch track (difficult to be honest for fm, as you want ratios) , then you need to sum pitch outside the 2osc (mixer?)
Forgive me if this is the wrong place to bring this up. A couple times recently, the 2osc’d module has stopped taking cv input for pitch on either channel. The cables were good and properly patched. Power cycling the unit cleared the error and the module was recognizing pitch cv from the moment it reenergized. Just thought it should be out there, if it hasn’t already been brought up elsewhere.
Hi, thanks for bringing this up! Can you see a certain condition for this behaviour or does it happen in different settings? How long does it work before the issue arises? As the module has a microcontroller onboard a software bug is indeed possible...
i tend to leave the ae rack plugged in. On both occasions, I noticed the problem as I began to play after at least a 24-hr period of inactivity. The first time, I unplugged everything and rematches the system. The second time, I only unplugged the power supply, waited for a moment, and then plugged it back in. It started receiving cv immediately after restarting, if that helps.
I'm having trouble getting my 2OSC/d to FM in the way that I would expect it to, but I'm not sure if it's my expectations or the oscillator that are off!
Could someone please have a listen to this audio file and tell me whether it is consistent with how it should sound in this scenario? 2OSC/d FM test
Patch: Osc1 saw (low, 10 o'clock) -> mixer -> Audio out Then Osc2 saw is connected with CV1 Osc2 set to high, Freq2 swept slowly all the way anti-clockwise Then Osc2 set to low and swept all the way clockwise
More and more convinced there is an issue with the oscillator...
When I try and calibrate it using an ES3 and CV Tools on Ableton it has a really hard time doing it. Often it won't complete because of too much drift even after the module is well warmed up - when it does complete I get this and it isn't calibrated in any real way:
This is compared to my VCO which calibrates like a dream and looks like this:

is the top on 2OSC/d ... thats a bit surprising, as mine was for the original 2OSC. if you use midi, does it sound out of tune in this range? that id say will tell you if its really a tuning issue or just cv tools messing up
I will say, Ive had issue with both Ableton CV tools and Bitwigs calibration at times on some oscillators, usually if its not a clear tone, also if you dont get the gain right you'll have issues. (e.g. if its too high it might distort, too low, and its not got enough to go on)
(once the new patch wires are in stock, I plan to get a few new modules including the 2OSC/d ... at which point I'll give it a test)
also looks like you have your VCO better calibrated than mine
