Multi-Channel Audio - one .wav file per output

I am trying to get multi-channel Audio working with a Motu box and having trouble with a particular issue - how to send a sound to a particular output, not just to a device. Right now I can detail with ofSoundStream to select that device and all my sounds are forced thru the first two outputs as the default Stereo pair. I cannot seem to find anything in the documentation about how to send something to a specific output on that device, for example - device 6, output #5.
I have looked into the great addon ofxMultiDeviceSoundPlayer but as the name suggests, it lets you send each sound file to a different device, but not multiple outputs on a single device.
Any advice is appreciated!

Wow, so, the thread just a few threads up mentioned ofxSoundObjects and it is exactly what I needed!!
