Updated FW, loaded my goto preset, and the output is like -80 dB. Oh my. Tracked it down to Cab2 Y getting trashed. The preset is giving the CPU warning, so I'm not sure if that is related to the block being changed. I checked a few other presets randomly but they seem OK.
Deleted a couple of blocks, set Cab2 Y back where it belongs, and it's working. But... the CPU is still 89%. That seems high for what is in the preset, and a quick check of the V4 factory presets shows the CPU warning on A002: Brownface (didn't check further).
Is this expected behavior?
