Pure Data Patch from Scratch: Simple FM Synthesis Sequencer

A quick and easy Pure Data patch-from-scratch tutorial building a sequencer that plays dynamically changing timbres for each note though frequency modulation synthesis.

In this patch, we set up a simple sequence of sine wave pitches (frequencies), then a sequence of modulation frequencies of a different length, then a random patterns of deviations, creating a constantly changing series of sounds.

There’s no talking on this one, just building the patch, and listening to it go.

0:00 Sequencing the pitch of a sine wave
1:23 Creating modulation oscillator sequence
2:45 Randomizing the deviation
3:15 Audio math: modulator frequency
3:51 Audio math: deviation
4:09 Audio math: FM synthesis
4:31 Tweaking the numbers
4:52 Commenting the code
5:47 Adding delay (as usual)
6:55 Feedback for the delay
7:17 Listening and more tweaking numbers

Chiptune Ambient (“Chip Ambient”)

Over the summer, I put together a video about time-stretching retro video game music in order to create ambient tracks:

I’ve not sure myself if I this is parody or not, but I now have a playlist where you can listen to 8 hours of time-stretched chiptunes that I call “Chip Ambient.”

Not guaranteed to improve your grades.

PlayStation 5, Tempest 3D AudioTech, and HRTF (Sony PS5 Immersive Audio)

The new PS5 audio engine, Tempest 3D AudioTech, creates 3-dimensional sound on any headset by using HRTFs, head-related transfer functions. So what are HRTFs? How does this work? Will it work for everyone? What does this mean for surround-sound setups? What are the five “Types” in the 3D Audio Profile Settings?

This video is a quick overview of what Tempest 3D AudioTech is reportedly doing now at launch (November 2020), and what possibilities and questions there will be in the future.

Reaktor 6 Primary Tutorials

I’ve put together a series of beginner tutorials for getting started designing your own synths in Reaktor 6 Primary.

Over the course of this series, we put together a synth with selectable oscillators, filters, and multiple options for modulation. This can serve as a good hands-on introduction to synthesis in Reaktor or any other synthesis environment.

EDIT (1/4/22): If you’re ready for more, here are some intermediate tutorials too:
