How are you guys going about updating the amp blocks without losing your settings? Should we write all the amp block settings down first? There has to be a more practical way to do this than unload, reload, and then reprogram the block, right? I'm thinking of Larry Mitchell who uses around 100 patches. He'll have to reprogram each one, one by one?
Some advice/counsel...
First thing you do always is to use FractalBot and save everything you have right now, the way you like it/love it.
ALWAYS do this before a firmware update, especially a beta. Because -- you can always go back, and all those old, loved amp settings are there. Security, ah. I believe a saved preset imported into a new firmware should be set to the prior firmware in amp block automatically, with all settings intact in fact. In amp block on one of the pages you can change it to say "latest firmware" if you always want it to change.
Then play with your presets/reset amp, you don't have to initialize the block though. Just change the amp listed in lower corner down to different amp then back up. Drive, Bass, Middle, Treble and Level don't change, BUT Master Volume and Presence/HiCut will, along with boost (if you have it on, it will turn it off) and bright switch will go to default position for the amp. If you have tweaked other amp page parameters, yes, you have to go back and reset those.
I have an XL and keep two raw amp banks, in mono, mono cab, basic amp and cab block and I try to set each amp with a Scene 1/2 Amp XY Cab XY setting that I can then audition when new firmwares come along.
Once this Q7.2+ goes final I will share that with the forum in all AXE FX and AX8 formats as a useful public tool you can customize to your hearts's content with your fav settings and cab choices... and with the last amp added (Dirty Shirley 2), it will now technical take 0-256 presets or equal to three banks space to hold every amp model, we've now crossed the second bank rubicon threshold...
