Although I did appreciate the suggestions offered on both PerlMonks and comp.lang.perl.misc, all of those envolved use of the MIDI device on a sound card. Good methods for use on a computer, to be sure. And I was glad to study them.

My script, however, went anouther route entirely, so as to write *.wav files playable on an independed MP3 player. So I did not actually employ any code suggested from either of those sources.

Had I employed code from one of those, I would have credited the supplier in the script itself as a comment...just as I did, in that very same script, for my modification of an array-shuffling sub found in the Perl Cookbook...which comment reads like so:

# Modified from fisher-yates_shuffle from the Perl Cookbook, 4.17.

I credited the original, even though I modified it significantly. Such is my usual habit. Should not that suffice?
