I have the latest firmware, no issues with installing it. While creating my own effects routing to run the 4cm with my pt100, I noticed some random freezing issues that required a reboot.
I set the layout up like on pg 18 in the manual doing the Super Serial layout...the first one. The unit was freezing intermittently
messing around with the pedal layout, especially when I would click on the Merge Mixer right before the 2nd output. IDK, it was random and definitely when I'd click on the Merge Mixer.
My temporary solution is to not click on the Merge Mixer..lol. Anybody else have something like this happen?
