Oscillator Detune Studio One 5

For some reason, when I play any note in Studio One, the detune parameter for Oscillator 1 gets set to -100 - Automation don’t fix it, and I can’t figure out what’s causing it - I’ve re-installed Studio One, and Vital - It only started happening a today and had been working for weeks - Super weird.

Any help greatly appreciated!

Right click on the detune parameter and select “Clear Midi Assignment”
