ill have to look at the book when i get to the office later, but
offhand a value 108 looks to be a typo
channel tuning in cm3 its divisions-per-semitone 1 to 16 so 1 is
standard semitone tuning, 2 is quarter tone, and 16 is a quantization
of 6.25 cents
you can get a good idea of whats going on if you use the Midi
or read the doc on mp:tuning -- in the editor click on the word
mp:tuning and hit Command-D
remeber you will only actually hear microtuning if you actually
generate floating point keynums, eg 60.1 where .1 means 10 cents
above key 60
