This first installment of my algorithms project has one primary goal, to automate as much as possible the creation of spectrogram files for use online and in teaching materials. For this and for all future posts I will upload the source files (only my original code and none of the artifacts of running said code)…

As I stare at the beginning of another Summer, this time with a toddler and a pandemic both raging nearby, I have set a few goals which I’m attempting to line up so they inform and help fulfill each other. First, don’t get COVID 19. Second, the rest. Here’s some of it. I will create…

It’s been so long since I’ve posted here or updated this site I almost forgot how the WP back-end works, yikes!  I hereby acknowledge I have been remiss and offer a formal mea culpa.  I have projects and experiments on my desk that warrant a post or three, some musical discoveries, and lots of news…

To the fledgling electronics enthusiast who has just enough knowledge of electronic music theory to be dangerous, it makes sense that the simplest tone, the sine tone, should be the simplest/easiest to construct in the analog electronics domain.  Of course, this is not the case.  While geometrically simple to describe, the sine tone is not…

It was to be the last MUSIC-N language he would write, and was…

There are so many good tutorials, books, and websites out there for learning SuperCollider that one may scoff at “yet another…” SuperCollider intro and for good reason.  This article, however, aims to answer really basic questions at the absolute beginner level, questions such as “ok, but how do I get SuperCollider and what version do…
