ofSoundplayer - sending audio to more than 1 stero channel

hi, what i would like to do is load in a stereo sample and play it on 2 stereo channels at the same time.

so far the only way i have figured out how to do this is to load it in twice into memory, each time specifying the device it is to be played on.

how else can i do it? can i get fmod to ask the system how many hardware channels there are then present me with an option as to which of these channels i want the audio played on?

cheers.
