Modular synthesis

Create your first patches with this free emulation

> Step by step Diving into modular with VCV Rack

1

There’s no better route to getting your head around the world of modular synthesis, than by downloading and experimenting with the free VCV Rack – grab it from vcvrack.com.

But we want to use our actual keyboard, right? Find it by scrolling through the Core MIDI > Device List within the MIDI > CV module. Boom, we can now operate VCV Rack with our keyboard.

The VCF module allows for the removal of certain frequencies, via its CutOff knob. This, in conjunction with your VCO’s Freq knob, lays at the heart of finding your first virtual modular sound.

VCV Rack runs as a self-contained piece of software. You’ll notice that a basic arrangement of virtual modules has already been predetermined.

While VCV Rack sets up a nice assortment of modules automatically, let’s rebuild it from the ground up. Lay out a basic selection of modules on one rack, as pictured (or in the following order) MIDI/CV - VCO - VCF - ADSR - SCOPE - VCA MIX - AUDIO.

Adjusting the ADSR module allows for fine-sculpting of the attack, delay, sustain and release of your developing sound. You should be sure to output gate and re-trigger control to here, too.

In the ‘Audio’ Module, select your audio interface. Once done, you’ll see that your inputs/outputs correspond to that of your interface. Generate MIDI notes by using the QWERTY keyboard.

Starting with the VCO, you can adjust pulse-width, frequency and select your source wave-form here. Drag your patch cables across from your waveform output to the corresponding input of the next unit in the chain.

At the end of the chain, you can manage output options with VCA Mix and Audio. Using this as a basic starting point, you can expand with a multitude of other modules and units to make your sound as fascinating as possible!
