Pulled in some of my usual presets from AxeFX3 that I'd already set up for DynaCabs, as a starter to try things out.
Last one of the import set, "Invitation P2: I/V/C/S - [9]" came in fine, just needed the first DynaCab channel unmuted and set to the Ribbon and the usual mic position, and all was good. Played it for a few minutes. Sounds nice.
Moved up to the "B'Man/Ojai 2 -4S" preset, and it came up howling. Went in and adjusted a couple modifiers to unstick the delay feedback and input and a couple other things that were on controllers not available on the FM9, and it shut up - until I unmuted the first cab block channel. After a bit of experimentation, I found that the howl occurs as soon as I run my guitar's volume up enough for its background noise to trigger the howl. Turn the guitar volume back down and it stops after about a second. The meters on the big screen show no signal in/out, but the SPDIF is pumping out a huge screechy noise. If I hit a string on the guitar while the volume is up, you can hear it modulating the screechy noise. Preset attached. Possible issue with imports from FX3?

Maybe not. Switched to an old, tried-and-true preset from the FM9 before updating, and it also screeches - a bit differently - but equally loud.

Going to try reloading the firmware and see if it just had a glitch in the install.
