- 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
