Hi!
I am also struggling with the MatrixMixer right now. I have a project which works fine in 2 channels
using the StereoMixer (mixing multiple stereo sources into one stereo output) and hope to be able to
turn it into a multichannel solution using the MatrixMixer (mixing multiple sources of 8 channels into
one 8 channel output).

I am connecting ConverterUnits to the mixer's input - so far, I could not get any output from it. Did
anyone else try that? I think I'll have to setup a separate project, just to figure out the MatrixMixer
outside my main app.

Its kind of nice to just think about this in one scope with just one

Thanks for this info. Makes it a lot easier.
I think we should add a little diagram to the Wiki entry, with showing which parameter affects mixing
in which place.
BTW, anyone going to MacExpo? I'll be at Stand 30, demoing Poser 5, if any audio developers from
this list are coming, I'd enjoy a little tech chat over coffee :)
