MOTM

Sorry for the OT, but I suspect folks here may have some useful 
information.   I am an analog guy, I do not know much about midi.

I am helping a neighbor in figuring out how to control a multi-
channel scary halloween display he is building in his front yard.   
The plan is to have several speakers strewn about the area and we 
want to play .wav files out to these speakers.   There may be about 8 
to 10 speakers, and we want to control what sounds go out to the 
speakers.

1) Can midi play .wav files?

2) Any suggestions on readings, software, hardware that may help in 
doing this?

Please email me offline, andy@... if you have any suggestions.

Thanks
Andy
