I had the same thing happen to me on a clean install. I had to go through and hit the download button on each instrument, but realized it wasn't actually downloading them again. It was simply relinking them. It was a pain for sure.
Can anyone confirm a mod wheel issue for me? Moving the modwheel with a mouse clearly moves the wheel (at least in the GUI), but does nothing to the sound. Moving on the mod wheel on my midi controller moves both the wheel and modifies the sound.
Bizarrre.
My question as well. I don't have any SA, but my upgrade price is $49. It obviously has many more synths than VV, but, do I really need it.
(Probably not).
