Hi, just ran into this manifesting as slews on outputs are taking roughly 2x the expected duration to complete. Verified with a timer at 5s / 30s / 1m. Crow v 3.0.1. Happy to do more testing if that would help!

Would this be something in the lua files, or something deeper? I might be able to take a stab if someone can point me in the right direction.

it's very likely some change in C. It's either an issue in lib/slopes.c
where timing values are being multiplied by 2, or it could be that the DSP loop has been slowed down by half. One helpful thing would be to measure the output samplerate. This is easily seen on a scope by setting a very fast lfo/oscillator on the output, and looking at the pacing of the staircase'd output.

Confirmed today that the DAC itself is running at 24kHz when it should be 48kHz. I believe this regression happened when we went to v3.0 but i'm struggling to find a culprit at that point in time. Going to do some quick tests to check that the system clocks are running at their correct speed, and see if there's anything else running at the wrong frequency.
