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.

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.
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:
