I have a gig tomorrow out of town, and found several of my go to presets went sideways in 2.80, too bad as I am loving the new models and control of the PC plus in the new firmware... Just running out of time to sort them out. Most of the problem presets involved the JTV where I was running 2 paths, one for JTV models, and 1 for the mags, where I would switch between the two paths. The snapshots wouldn't switch and hxe reported not reading the snapshots correctly. Figure I'll have to recreate those presets IN 2.80, as something got lost in translation somewhere... Another couple were straightforward amps with snapshots controlling gains and such. Not enough time to troubleshoot. Rolled back to 2.71, and restored from my backup, and they all worked again. Will redo the update next week when I have more time to sort them out.
