Since getting the Syntakt I found myself with a lot of questions about the Dual VCO, and a MiRack oscilloscope has answered a few of them:
What’s the closest we get to square waves and pulse-width modulation?
What is the oscillator phase reset on half the configurations?
How does balance work on Ring and FM and FM + R configurations?
I took a video of my findings as hopefully a beginner-friendly guide to a few things the Dual VCO does well:
cool stuff, I’m going to apply some of the tricks on my AR…
Great ST sound design tips in general! Gonna recreate some of these today - thanks for sharing
Thank you, that vid helps a lot!
Thanks, I’m keen to see how you did your hoover. Mine sucks 
It’s the last trick at the end of the video.
Ha! I wouldn’t hold it up as definitive (I’m sure there are many ‘Nauts who could do much better), and it’s half an excuse to show how noise-rate modulation works, but I’ll be eager to see if you can improve on it!
Edit: looks like I forgot to mention it uses chorus; also, using portamento/bend and p-locks for the pitch envelope could free up an LFO to add more sheen somewhere…
really good video. i like your videos - hacks and tricks:-)
Thanks, that’s kind of you to say!
Welp, the “how do I get close to a square wave” bit had a short shelf life! Syntakt SY Raw machine overview // Creating a patch from scratch using the Syntakt 1.20 upgrade - YouTube
