info on Kurzweil 2500

My friend Lee Stametz and I are beginning work on a new play here in
Denver, which will contain some (I don't know how much yet) non 12 equal
music. Lee will be using a Kurzweil 2500 synth, and would like info on
it's microtuning capabilities. If anyone out there can help, please post
Lee directly at stametz@aol.com...much appreciated...Hstick
