Maybe he is interested in the MultiSampler plugin Natanael did. It is 
available in the osc plugin. Not exactly what he wants but an starting point.
We used it to trigger sounds from the YoFrankie Blender game using OSC.

Sadly, such plugin was dropped from the debian packages. But by installing the 
dev packages you should be able to compile that plugin alone.
