I'm a guitar player, a composer, I have a Mac and a Roland XP-50 with a GI-10. Can you recommend any particular composers or recordings I should listen to help me broaden my horizons? I have a specific question regarding my XP-50: it has a function called *Keyfollow* which allows me to tune the keyboard using percentages. +200 gives me a 6-tone (whole-tone) scale, +150 gives me an 8-tone scale (the negative values reverse the keyboard), and if I tune the proper pitches 50 cents sharp (or flat) I get a diminished scale. It's very interesting (and fun) to take something like a Bach midi file and listen to it using one of these tunings. +120 gives me a 10-tone scale. +50 gives me a 24-tone scale. Now, +70 gives me a 17-tone scale, +40 gives me a 30-tone scale, +30 gives me a 40-tone scale, and +20 gives me a 60-tone scale. With these tunings, though, I can't really tell (I guess my ears aren't good enough yet) how accurate the octaves are, and I don't know how to figure it out mathematically. Can anyone tell me how accurate these octaves are, just from the *numbers*, and are these um legitimate or *actually used* scales (I've heard of 17-tone, 24-tone, and I think 31-tone scales?)? Excuse my ignorance of proper terms, thanks for the help, and do these scales have proper names? Is there maybe a good book someone can recommend that would explain a bit about *microtonal harmony*? P.S. Mr. Haverstick (sp?), I've heard of you. Don't you have some guitars that are um fretted differently to allow you to play *microtonally*? I live here in beautiful Westminster - when and where might I be able to hear you play some music on some of these instruments, and where might I check one out?
