Hey,
Since a while my second oscillator keeps detuning, sometimes it’ll start out right around the correct note but glide down (always down) to a lower pitch, usually around minus 60 cents from the note you’re playing and then it will slowly fluctuate up and down from there. Does anyone have any idea https://soundcloud.com/bomerijn/sub-37-osc-2/s-IikQKUXXI7P?si=ecf2c96ca5464d23a6c5c863ef4099a6&utm_source=clipboard&utm_medium=text&utm_campaign=social_sharing Here is a link with an example, I’m playing a C but the note coming out is about 30 cents above B and fluctuates.
If anyone has any idea what could be causing this I’d love to hear your input, and don’t shy away from the easy answers. I’m a working musician but not well acquainted with synths at all 
.
Thanks a lot!
