Thanks for the additional feedback, The sources are actually all software rather than any hardware microphones. I also have the gate plugin inline with each of the 4 inputs, prior to feeding them into my plugin. It was really written, so I could have music, ISS Audio, Gaim notifications etc, and If any of the Astronauts say something, or someone logs on MSN/IRC, then any music I'm listening to gets overridden. It currently works for me, but I need to do some cleanup, and do a stereo version. I'm also thinking of a modified version to handle the situation where I'm outputting audio to my 5.1 Home Theatre system. I had named it 'PrioMux' (Priority Multiplexer), but if the correct term is 'Auto Mixer', then I can easily change it before release. Best Regards Iain
