I´ve started a new series. And – again – it´s about modular synthesis. I thought SoloStuff´s modular softsynth “SoloRack” worth a whole series of tutorials – and concipated one. Here is the first part: Installation and Overview

It´s a public part. Enjoy it! Rolf

The second part of my series of tutorials about SoloStuff´s modular softsynth “SoloRack” is online now:

In this second part of the series I talk about the menus and the hidden functions of SoloRack, give some explanations about oversampling and aliasing and build up a famous patch step by step (please see the timeline for details).

The whole series is meant to give you not only a profound knowledge about the modular softsynth SoloRack, but also a remarkable amount of knowledge about modular synthesis and even about sound synthesis in general. It makes it easy to step into the matter, even if you are a complete beginner (You are a professional? Well, you may like the series nevertheless).

My last “modular” video in 2017 is out now, SoloStuff´s Solorack part 4, talking about three of the oscillators.

It´s about saw, supersaw and hypersaw, about linear frequency modulation, about exponential sine wave FM, about noise and “Radio”, about Karplus-Strong and about a mysterious patch.

I´ll be working on my album for the next 6 weeks. So, please don´t expect my next video before the end of January 2018. I wish you all a merry Chrismas and a happy New Year.
Enjoy your life!

Part 5 of my series of tutorials about SoloStuff´s “SoloRack” modular VST synthesizer is available now. It is all about frequency modulation – linear as well as exponential – and phase modulation. The video introduces and explains the S321 FM/PM oscillator module.

1 hour and 40 minutes long, more than 39 hours of production time, 54 graphs and pics, 69 short clips, and here is the
