10.3. Using MIDI to Control Modules in VCV Rack

In the example below, we'll use a KeyStep Pro arpeggiator to control an oscillator in VCV

Rack, a free virtual modular system that you can download from

https://vcvrack.com and

install on your computer.

• Connect the USB output on your KeyStep Pro to a USB port on your computer

• Open VCV Rack. The first time the program launches, it opens a simple demo

patch, which is perfect for our example

• In the first position (top left), you'll see a MIDI-CV module. We'll use this module

to get MIDI Note Numbers from the KeyStep Pro, and we'll use them to control

the pitch of a VCV Rack voltage-controlled oscillator (VCO). We'll use the

corresponding Velocity values to control the ADSR envelope generator module

• In the upper menu of the MIDI-CV module, select "Computer keyboard" and

change the value to "Core MIDI" or "Windows MIDI", as appropriate). Then, in the

middle menu, Click on "(No device)" and change it to "Arturia KeyStep Pro". We've

now set up the MIDI-CV module to receive pitch and velocity values from the

KeyStep Pro

• Now, in the middle menu of the Audio-8 output module, click on "(No device)" and

change it to the computer audio output (i.e. internal soundcard or external audio

interface).

Now, when pressing a key on the KeyStep Pro you should hear sound from VCV Rack

through your speakers or headphones. Congratulations! You can now use the KeyStep

Pro keyboard, the arpeggiators and the sequencers to control oscillator(s) and envelope

generator(s) in VCV Rack.
