Yes AAX64 is a must to keep the product valid and alive. I also use the individual plugs a lot, the mod fx, the preamps…. but the 1st step is to make PF2 AAX64 ready, then do HD. My workaround is using Waves pedalboard stuff and Eleven amps, or Guitar Rig5 (which now works with PT11). Don't make me say goodbye to PF….
