First, I don't make money off this—there are no ads on my site, no products. I write because when I was figuring this stuff out, there was no internet, and the text books were tough to read and didn't tell me what I wanted to know...

I'm well into a multi-part article explaining the rationale behind wavetable oscillators, and how to make them in software. It starts with an introduction, here, followed by parts 1-3, with more to follow soon:

I'm not big on self-promotion, but if no one reads my articles, there's no reason to write them. So, I just want to let people know they are there... :wink:

I'm glad you posted this, because the discussion on MIDI is quite relevant to my current efforts - thanks!

Thanks for this and for your other tutorials. A lot of these concepts are really not that difficult but most of the published literature is written in an overly formal & academic style that makes them seem much more esoteric than they really are.

I'd love to see a book written in this style that covers the basics of DSP coding.

A good tutorial, I would have loved it when I first learned about this stuff.

What a great series of articles, bookmarked.
They might even become of huge interest for me, should I try to improve the oscillators in my sequencer (as of now, they are simple function outputs).
Keep up the great work !

I remember the blog! Very cool articles there! Have been opening the blog for a while some time ago (and some of the articles recently also).

Good grief, this took a while...I'd mostly written an "end notes" article to the series back in June, but got a little overwhelmed between trying to make sense of cramming a bunch of different ideas in there, and a busy summer, work-wise. Finally, I got around to finishing it and getting the audio examples up:

And thanks for your comments, everyone. I only do this hoping that it helps a few people, so the positive comments are appreciated.
