Attached is a little abstraction that I sometimes use to simply pan over multiple speakers. It's an extension to the usual cosine-based panning for stereo, but made for more than two speakers. Sorry for the help file that's not up to my usual standards. :) Anyway the [cospan] object has to be created with two arguments: The second one gives the number of panning steps or segments (i.e. the total number of speakers minus 1), the first one indexes the speaker. So for four speakers, create these objects: [cospan 0 3] [cospan 1 3] [cospan 2 3] [cospan 3 3] then send the position as a number between 0 and 360. You can also change the width or spikiness by sending to the global receiver [s COSPAN-WIDTH]. Its value is used a a [pow] exponent. The output of [cospan] at the first outlet is between 0 and 1. The second outlet generates messages suitable for [mtx_mul~]. Ciao -- Frank Barknecht Do You RjDj.me? _ ______footils.org__
