I have a very poorly tracking VCO. I also had a performance outside today. (Yes, in the cold.) I knew tuning would be a challenge, but after bringing the unit inside and letting the pitch settle, I have one VCO that is tracking very poorly. It won't even track an octave. I was wondering if the FMOS and Wavetable oscillators track better since they are digital?
I plan to do more performances. I'm wondering if I'd be better of with digital oscillators instead of the analog VCO? I don't have time to be calibrating every other night.

I'm not much of a "the thing is tuned" kind of guy, but i think The osc2/d is more stable and better tracking than the purely analog oscillators.
The FMOS is digital but it's kind of another beast. I find it hard to get the FMOS in tune with other oscillators when i try, but i jus love it so much for all it's sonic capabilities.

The digital oscillators are much more stable than the VCO; the thermal drift is a severe challenge with all analog oscillators.
For the newer AE friends: In the beginning, AE modular was not even intended (at least at the beginning) to have 1V/Octave pitch control; it was mainly intended as an "analog noise machine", as source for analog based samples, things like this. But already during the kickstarter campaign the backers wanted "classic" oscillator tracking so badly that I had to develop them quite quickly. I'm aware that the current VCO is not the best, especially with significant temperature changes.
BUT: Currently I'm working on a completely new (true analog) VCO,based on a high class chip, that will replace the current module; removing one more legacy of the initial AE modular and bring it one step further towards a "serious" modular.
I hope this gives an idea of the background about this topic ;-)

Analogue oscillators and temperature (especially extremes) are not friends. That careful balancing act needed to get them in tune, stay in tune, and then stay in that tuning over more than just a few notes, is thrown into turmoil. Sadly, it's not new, and it's basic physics - as Tangerine Dream found almost every night, especially during those famous Polish concerts of 1983 (including the very famous Ice Stadium in Warsaw).
So, we're in good company  |

I don't know where you live at Funbun, but if it's as cold as chicago, I salute you. But even before covid, when we could do gigs inside, and I was just using eurocrack, I would favor digital signal voices for performance. Finding a note with a knob is just as easy as doing so with an upright bass on digital stuff, analog can be a nightmare. |

Thanks, everyone. I ordered a pair of FMOS modules and wavefolders from Noisebug. Will probably order a pair of GRAINS modules next month. I'm hearing more complex waveforms these days. Now is a good time to rethink my oscillators. Two FMOS oscillators with wavefolders and a pair GRAINS should give me years of exploration and sonic possibilities.

narcoterror probably not a chilly as Chicago, but still ...
-2C at night
(I don't think I've been under 5C for about 2 years, but Sydney is about level with Buenos Aires, I think.)

funbun Paula is talking about bringing her WTF oscillator to the AE format soon for some very gnarly waves.
(but probably without the neat little scope display to save space) |
