Press Master, scroll to Local Control and switch Pots to “OFF”
Press Panel (maybe 2x) go to Parameter Display and select “YES” or “3sec”
Now turn a couple of Filter type knobs to see the readings are changing from one knob to another
Now Turn Osc 2 Freq knob. And then turn any other knob. Is the display stuck on Osc2?
You can turn local control of Pots back to on to get out of this.
Osc 2 frequency appears to be the only parameter that locks up the display. After reloading 3.6 with no change I reverted back to 3.5 and the issue is not present. I then reloaded 3.6 again and the issue returned.
