Using PodFarm 2.57 in standalone or in protools 10 on windows 7 64bit with all model packs with everything authorized. If i load a factory preset everything loads and works properly, i can load all amp models with no issue, if i tweak it and then save it and then reopen it, the PreAmp section doesnt work, I can move all knobs from 1 or 10 with no audible difference, all other aspects of the preset work, i end up having to reload a factory preset and retwaek all over again everytime
