Unbelievably good for the money. Woodwinds, brass and strings are great. The piano seems very deep. The Big Bang orchestral percussion crashes whenever it receives MIDI. Oh well, maybe it'll get updated?
You need to click on the "Learn" button first before feeding it any MIDI. Obscure, I know, but it seems to be the only workaround. I don't believe for a minute that these plug-ins will ever be updated but I picked the whole bundle up for $20 and many of the sounds are very good indeed.
