[Coco] SirSound serial port sound device demos.

[Allen Huffman]

I have posted my two SirSound demos to YouTube:

SirSound demo 1- introduction

This 7-minute video walks through the basic concept of the device, and shows how easy it is to convert BASIC "PLAY" music to use the SirSound device.

SirSound demo 2 - polyphonic music

This 4-minute video shows how multi-voice music will be handled. It demonstrates 3-part harmony, and also a quick version of the Frogger arcade game theme music, all from BASIC.
