mono sounds to left and right sound channel

[Axel Buchner]

Does anyone know how to take two mono sounds and play them 
simultaneously to different sound channels, one to the left and one to 
the right channel?

I need to do this with a large number of sounds using random pairings 
of sounds which is why combining the mono sounds to appropriate stereo 
sounds is not an option (it would take forever). For HyperCard and 
MacOS 9 I had an XFCN that did the job, but with Revolution and MacOS X 
I am lost.

Thanks, Axel
