I just purchased C6 yesterday and it is working fine except for this:
I load up Sonic SE, pull up the media bay, I have it set to attribute and I see my filters: category, sub-category etc., but nothing in the results window. I have gotten the piano sound by using the beginning template of piano and voice, so I think these presets are somewhere. It is just not pulling up in the media bay.
Here is a shot of my Media Bay, with All Media chosen, which shows no instruments, my Mini Browser with the VST Sound chosen and only showing a few instruments, then my Mini Browser with the All Media option chosen and showing all the Sonic SE instruments. I can create a track from the mini browser, but it would be nice if I could, like in previous versions, create an instrument track, load Sonic SE, and then load my instrument.
