sure but realize that when floating point keynums get written to  
files their actual channel values are ignored, ie the notes are  
assigned to the appropriately tuned channel in the stream. this means  
that you lose channel information in the file for retuned notes.

the value is the number of divisinos per halfstep so doing ':channel- 
tuning 2' gives quarter-tone resolution, ie

	(events (foo) "qt.mid" :channel-tuning 2)

means that channels 0 and 1 will be used for quarter tones quantization.

in a related matter, import-events now parses floating point keynums  
from midi files if you specify :channel-tuning t to it. this is not  
documented yet.
