If I tweak a patch (not saving it), then select another patch, and then return to the first patch, it's still tweaked.... It would seem to me that once you step on a footswitch to recall a preset, it would come up in the saved version, not the temporarily tweaked version. Especially with dual patches - if I disable "dual", and then step again, it should re-enable dual - sometimes it does, sometimes it doesn't. This happens on both my x3 pedals........
