Actually, I read about v2.5 having code/algo/DSP/whatever optimizations, that is: More juice! I think it was DI who said that, don't remember where, and I had totally forgotten until I loaded one of the patches I use with my A band, the band I'm using Helix with. It's a patch where I'd need different dirt options and I can't get them because I'm running low on dsp, so I try to load a different one than the one that's there and I notice that I now have like twice the HX drive options I had before but... the whole legacy bank of drives appears greyed out??? Do legacy drives actually require more dsp than the HX ones or have I just found a bug?
