Sorry, but I have to say that none of this will make a particle of sense to someone who would be asking such a question. A rudimentary question is a wonderful an opportunity to distill everything down to a simple understandable concept. Her

"FM Synthesis" is a generic term that encompasses both phase modulation and frequency modulation. And in John Chowning's original article, he bops back and forth between the two without mentioning it. In practice, phase modul

It may be; I don't know enough about it. I wrote these a while ago... should've dated them.

Correction; the senator meant to say the Buchla 258 oscillator had linear FM. (Although there were variations!) The control voltage input goes through the exponential converter, and the FM input sets the bias of the exponential converter.

"Hammond Organs are distinct and popular, but nowhere near as ubiquitous as the DX7." Dude... There were about 200,000 DX7s manufactured. There were about 2 million Hammond Organs manufactured.

Interesting. I agree that the article is an exaggeration. It could be argued that the DX7 had a significant negative musical contribution. Oodles of sounds at the expense of musical expression. The musician became alienated from the proc

For some reason that version has a large number of audio glitches. But very recently the Computer History Museum published a cleaned-up version: https://youtu.be/lw6TaiXzHAE Good!

The Triadex Muse was a digital algorithmic music composer invented in 1969 by Marvin Minsky and Edward Fredkin at MIT. The Muse is incredibly rare; one report claims that only 280 were built, and a small fraction of those are likely in work

Very often a variable name needs to provide more context. I have found it very useful to use under_scores as a form of punctuation within camelCase to visually connect related variables. Like this: spectrumPlot_x spectrumPlot_y spec
