It's not the DL, it is the "automatic installer" for say some VST included SPro instrument package. You apparently do the manual process from the store, so I'd like to report that C3 is no more efficient. I keep trying C3 out to provide feedback. Note how particularly true this is for some suggested parallel 32/64b installations to recover those 32b VST tracks with having to render down to audio. There's another thread on that.
Well, I'm just working on dinner, so I'll give it a try. Let's see how this works across a reboot.
Meanwhile, I've put on my Jefferson Starship 'Dragonfly' on vinyl, and it's clean. I think I can link back as an input to my USB interface via a HW mixer.
