Amplitube is as good as anything else out there, but everyone seems to have their favorite amp sims. Some of the older stuff is perhaps less stellar but I’d recommend the new amplitube 4 amps plus the newer signature add ons like the fender collection 2. I also use Mesa and Ampeg a lot.
So I picked up the Evolution Songwriter, but I'm noticing the time for the progress bar to load samples into memory (not the initial load) is over a few minutes (off of an SSD, after a batch resave).
Anyone else experiencing that?
