Care to elaborate on this any? Is it amp modeling related? I am leaning towards no, since it's not an upgrade to 13.xx firmware.
I am guessing he is referring to the tweaks he has done to power amp modeling. They released it in the FM3 already and I have to say it is noticeable. I put my FM3 into pro tools using an IR plug in for cabs and put my Marshall Plexi Hand Wired loaded down with a Suhr RL into pro tools with a IR plug in and compared the 2 side by side and it is craaaazy close. Just about dead on- I feel like individual notes bloom more, chords sit in the recordings a bit better, and the sound of the amps just sound a bit more alive. It’s not like everything has changed, yet somehow it has. Hard to explain.
