Hi I discovered a mistake in the documentation. On http://chuck.cs.princeton.edu/doc/program/ugen_full.html#pan2 it is suggested that .pan goes from 0 to 1, while in fact it goes from -1 to 1, with 0 being center. I didn't try but I bet other ugens with pan work the same way. Should be updated in the documentation... -- peace, love & harmony Atte http://www.atte.dk | quartet: http://www.anagrammer.dk http://www.atte.dk/gps | compositions: http://www.atte.dk/compositions
