Just looking for some clarification on the functionality of the MatrixMixer. In my program I am going to have a variable number of inputs (buses) in the mixer with a variable number of channels. Now I know that each bus can contain 1+ channels based on how you define the StreamFormat for that bus.
So my question pertains to setting the crosspoint volumes (aka kMatrixMixerParam_Volume with kAudioUnitScropGlobal) and working with variable audio file types. If you have a stereo file, thats cross points 0 and 1, then you connect a surround file with 6 outputs, so thats crosspoints 2-7 ...
There doesn't seem to be an easy way to calculate what the crosspoint in values are on the mixer based on the mixer bus a generator is connected to. Is this just something I need to keep track of, or is there a better way that someone out there knows?
Thanks
