It seems to me that the strength of Real Tracks is in their ability to replicate those instruments that are notoriously impossible with synths, due to the complexity and nuance of the sound. Given the popularity of Celtic music, and the fact that I've never heard an acceptable MIDI rendering of bagpipe or many other acoustic instruments commonly used in Celtic music, I think that a set of RT geared toward this style of music would be very well received. *I'D* definitely buy it!
