Dear chuckians… This is bizarre… I was sure I have done this in the past, but it isn’t working and now I’m a bit flummoxed…. Any ideas here? PS: I’m trying to route channels 0 and 1 of a stereo .wav file to dac channels 2 and 3. Should be simple. So why doesn’t this work?? I realize that I could just spit it into mono files… but why? I thought SndBuf supported up to 8 channels. — SndBuf sb; //read in stereo sound file "snd/squeakies/bell_4.wav" => sb.read; //works - and routes channel 0 of sb to dac.chan(3) sb.chan(0) => dac.chan(2); //doesn't work - claims NullPointerException sb.chan(1) => dac.chan(3); 1::minute => now; —ss [ - ] Scott Smallwood http://www.scott-smallwood.com/ - Associate Professor - University of Alberta [ - ]
