VCV Rack 2 is a virtual Eurorack modular synthesizer, complete with a generous selection of modules and flexible virtual patch cabling, and Rishabh Rajan's new course "VCV Rack 2 Explored" shows the potential of this excellent virtual synth. Rack 2 is an update of VCV's original Rack modular synth, and is available as both a free cross-platform standalone application and a reasonably-priced plug-in. Modular synthesis can be daunting, so the course starts out by demonstrating how to a create a basic patch from scratch. From there, it covers every VCV Rack module in detail, including VCO (the basic sound generator), VCF (shapes tone by filtering the raw oscillator waves), and VCA (controls amplitude). It then dives into modulation, showing how to shape the sound using ADSR Envelope Generators and LFO modules. The course also covers the Sequencer, Quantizer, Random Generator, and lots more. Rishabh includes plenty of patching examples -- the course demonstrates everything needed to create custom sounds with VCV Rack 2. For anyone who's interested in modular synths but hesitant to invest in Eurorack hardware, Rack 2 and this course should be the perfect combination for jumping into the creative world of modular synthesis.
