Using Midi To Control Modules On Vcvrack; Keystep Control Mode And Vcvrack - Arturia KEYSTEP PRO User Manual

10.3. Using MIDI to control Modules on VCVRACK

Another option is to control MIDI-enabled software on your computer. In the example below,
we'll use the arpeggiator of the Keystep Pro to control an oscillator on VCVRACK a free
virtual Modular system you can download from https://vcvrack.com](https://vcvrack.com/))
• Connect the USB output on your Keystep Pro to a USB port on your computer.
• Open VCVRACK. It will open a demo which is perfect for our example.
• In the first position, you see a MIDI-CV module. We'll use this module to get
Note values from the Keystep Pro and use those to control the pitch of VCVRACK
oscillator and the and Velocity values to control the ADSR.
• Click on "computer keyboard" in the MIDI-CV module and change the value to
"Core MIDI". Click on "no device" and change it to Arturia Keystep Pro". We've now
set up the MIDI-CV module to receive pitch en velocity values from the Keystep
Pro.
• Now click in the Audio-8 module on "no device" and select the output of your
system.
When pressing a key on the Keystep Pro you should now hear sound from VCVRACK.
Congratulations you can now use the Keystep Pro keyboard, the arpeggiator and sequencer
to control Oscillator(s) and Envelope generator(s) in VCVRACK.

10.3.1. Keystep Control mode and VCVRACK

As seen previously CC# values can be used to control parameters on external synths and
modular systems. These control codes differ from the note related MIDI messages. CC#
codes are specifically designed to control parameters on an external MIDI device, on a
Modular hardware system or a software Modular system such as VCV Rack.
10.3.1.1. Sending CC# codes from the Keystep Pro
To send CC# codes to external devices the KeyStep Pro has to be in Control Mode.
The moment you press the Control Button the 5 encoders take on a different role; they will
transmit CC# codes over MIDI.
Here's an overview of the default CC# values the Keystep Pro over MIDI.
