Hmmm, try getting the oscillators to tune in the Arctic...
I wonder if it has any 4000 series CMOS, they don't like the cold either.
Tis the other way around.
CMOS is fine when cold.
Heat is the destroyer of semiconductors.
Quote from Wikipedia...
Conventional CMOS devices work over a range of -55 °C to +125 °C. There are indications that silicon CMOS will work down to 40 kelvin
There's also superconductivity.
This is a whole field of science dedicated to the benefits of cooled electronics.
Btw, if the VCOs were tuned when cold and the temp remained the same, so would the tuning.
Going from cold to hot (or vice versa) is where drift and scaling issues come from.
There are days here when I can't calibrate a synth because the temperature can change so widely and quickly.
It can actually be 80F in the day and 30F at night.
A change of 50 degrees in a matter of hours isn't so much fun when tuning a synth.
Especially a big polyphonic with 16 vcos.
As soon as you're done, you have to start over again..
