I’ve had wifi on, but switching it off doesn’t seem to make much of a difference.
After some more poking, this actually doesn’t look like an issue isolated to start/stop. I’ve just got general interface lag on almost all functions, except for changing the track focus, and starting/stopping recording.
Update: After power cycling Norns and re-recording some new stuff, the issue isn’t happening anymore. Is there a way that I can grab a sample of the process over serial if this happens again to help with possible debugging?
