I was thinking about multiple voice chords and I see dac described in the Programming Guide as [ugen] dac * digital/analog converter * abstraction for underlying audio output device so I thought that it could be the target of multiple ugen's in one shred, and tried it here http://garywilliams.org/chuck/bpmulti2.ck It seems to work. So I used it as the basis of an article on http://b-chuck blogspot.com/. But I notice that if I use multiple instances of this chuck bpmulti2.ck bpmulti2.ck it generates interference. Is multiple dac usage legal (and proper)? And does anyone know why multiple instances generate interference? --Gary Williams ---- Chess: http://chessnut.net/ Homepage: http://garywilliams.org/ Blog: http://tfs_reluctant.blogspot.com/ ChucK Blog: http://b-chuck.blogspot.com/ Resume: http://garywilliams.org/resume.htm Store: http://www.cafeshops.com/tfsreluctant/ Phone: (607) 775-0408 Permanent email: gwms@corninglink.com
