Hi,

just a few more questions about the MatrixMixer:

Can I use input streams with more than 2 channels? I don't get an error when I set the
AudioStreamBasicDescription of an input to e.g. 6 channels, but after doing that, I can't connect any
nodes to its input any more. Trying to establish a connection returns -10865 -
kAudioUnitErr_PropertyNotWritable - what's that supposed to mean? The same code works fine when
I set all the AudioStreamBasicDescription to have 2 channels.

Is there a way of changing the number of input streams while the node is running? I have a case
where input streams come and go, and I'd much more prefer changing the dimension of my mixer on
the fly instead of allocating a max number of streams and having most of them idle all the time.

Thanks,
Stefan
