there's no real notion that an AU can't support any of the 16 possible
midi channels.
However, many au's will be mono-timbral (that is they will only play
one sound at a time)
Can you describe the problem you are having, what you would like to
know and why?

Hello,
I am wondering how audio unit host applications can determine the
number of MIDI channels supported by music device audio units. I
have read these messages in some detail:

http://lists.apple.com/archives/coreaudio-api/2003/Jul/msg00400.html
I have tried using kAudioUnitProperty_ElementCount on the Group
scope(element 0) and it gives me "0" when querying AUs that I know
support at least 16 channels. There are host apps out there that
provide the user with a number of output channels corresponding to
the number of MIDI channels available on the AU, so I assume there
is some way to determine this.
Any advice would be appreciated.
Thank you.
James
