midi quantize

[Gordon Kent]

Hi:
Has anybody had any success using the midi quantize settings dialog?  I can 
quantize a selection but I haven’t figured out how to adjust the amount of 
swing.  I see two fields next to the swing button that say 0 and 100.  Are we 
supposed to drag some sort of arrow in betweenthose values to get a value like 
30 or so to get a subtle swing feel?
Thanks
Gord
