RemoteIO: setting different channel count for Input and output.

Hi,

I was trying to set audio input to mono and output to stereo using two ASBDs for one RemoteIO AU, which is the only AU there.
Then I registered two separate callbacks for input (kAudioOutputUnitProperty_SetInputCallback) and output (kAudioUnitProperty_SetRenderCallback), and expect that in my output callback, with AudioBufferList *ioData, ioData->mNumberBuffers should be 2.

But, to my surprise, it is still 1.

Is it that RemoteIO does not support having different channel numbers for input and output?

Thanks,
Beinan
