One thing that Next doesn't document well is how to get sound into
our machine. I don't mean through a mike, I mean recorded, short sounds
that play back cleanly. Can we use the microphone port or DSP port 
hooked to a sound source? If so, what is some good cheap software to 
control the input? 

Thanks
