Hi, I've been testing with Mainstage and discovered that it seems to respond to midi messages no mather what channel you specify. For example, if you send program change on channel 5 from your MFC, Mainstage reacts even if you have assigned channel 1 to your instrument. I checked the manual and internet forums but I can't find a way to filter midi channels in Mainstage. Does anyone know a workaround, some filter program on OSX level? --- Sjaak http://sjaakovergaauw.com/ http://euroloopfest.com/ http://last.fm/music/sjaak+overgaauw
