The principles of how to code sound and music on a "bare CoCo" are
covered in William Barden's Assembly Language book as MUSSYN.

Rainbow Magazine, June 1984 has an article "Making Four-Part Harmony
Easier" with the Music+ program.

Rainbow Magazine, June 1986 follows up with Music+ for some updates and
new commands.

Rainbow Magazine, June 1987 has an article called "Steppin Out with my
CoCo" which details the Bells and Whistles 2 multivoice program.

32K Extended BASIC CoCo 1/2 compatible.

The code should already be typed in/available as binary on the Rainbow-
on-Tape and Rainbow-on-Disk.

Finally, search the TRS-80 Color Computer group on Facebook file area
for Simon Jonassen's example sound code - 1, 2, and 4 voice code with a
variety of options and more...
