I'll have to pass on this. A year ago I'd have jumped on it, having been a longtime Miroslav user.
But when ST2 stopped working (after moving to Win 8.1), I had to look around for a replacement. That ended up being Kirk Hunter Concert Strings, which turned out to be a good choice. It has its limitations, as they all do, but it sounds great for the lush backing tracks I like so much. Sorry, Miroslav, you came along too late.
