| I have been beating my head against this problem for days - I'm trying to use all of the inputs on my MOTU ultralight - sticking a matrix mixer in between the inputs and outputs.
When using MusicDevice AU's I set the stream format to be two channels - so each mixer input is magically stereo when making connections. I just make a single node connection and both channels of audio are part of that connection. This works fine.
AUGraphConnectNodeInput(mGraph, synthNode, 0, mixerNode, channel-1 )
AU======MixerChannelInput
What I can't figure out is how to merge a pair of input jacks from the ultralight into a single two channel input (like what they call a Stereo Bundle in DP). Each output is mono. Do I need to interpose an AUStereoMixer before the channels to do this?
Input3------\ AUStereoMixer=======MixerChannelInput Input4------/
assuming I want a left and right channel - or if I just want mono to stereo conversion do I do
/----------\ Input5-----AUSplitter AUStereoMixer=====MixerChannelInput \----------/
Or is there an easier way? |
