Treellama graciously agreed to finish up beta 4 and let me do the recording, so a full set of digital-audio captures are now ready for your listening pleasure.

These were recorded with muZak's "Normal" volume, to avoid clipping. For actually listening, they're a little quiet, and could benefit from some post-processing; the QuickTime 2.0 instrument quality just isn't up to modern standards. I'll leave that to those with better ears and experience than me.
Hamish, Craig, feel free to host these and/or modify as you see fit. And thanks to everyone who encouraged this mad experiment!
