Title: Weird Oscillator Drift
Post by: TcTT on July 09, 2021, 04:51:33 pm
Hi,
Firstly, I waited more than an hour before checking and trying to calibrate the oscillators.
I just got a Minibrute 2S and find that I can't calibrate the oscillators to be consistent in the lower two octaves. The best I can get it is to have all the octaves between -1 and +1 cents, which I think is perfect, EXCEPT the second lowest octave is 6 cents sharp and the lowest octave is 23 cents sharp.

I don't understand how there is no drift from C2-C6 but C1 of quite a bit off and C0 is WAY off.

I have used the calibration screws on the back, but any change I make to VR2 or VR4 make everything drift too much one way or the other.

I hope I am missing something and someone can point me in the right direction.

Thanks
