Tried the firmware and having the same issues , especially on patches with Beefaco modules.
Edit:
After further playing with the fw it fixed the issue on other patches except ones using Beefaco modules, especially when using the NoisePlentora , I get about 5-10 min of playtime before it goes into high pitch noise and the unit freezes and requires reboot .
Just noticed that if the cpu reaches 70+
The module crashes , the sound is still there and auditable via button set selected but the screen and buttons are fully non responsive
Again all this is using one or two beefaco modules (which are awesome modules btw )
