Arturia KeyStep Pro Keyboard with Advanced Sequencer and Arpeggiator - Manual (Page 144)

When the KeyStep Pro is in Control mode and you turn one of the five main encoders, a
CC# message will be transmitted. The default CC# messages that will be transmitted are:
Encoder CC#
Pitch 74
Gate 75
Velocity 76
Time Shift 77
Randomness 78
The problem with CC# messages is that you may have no way of knowing whether they are
being transmitted, unlike notes that will either sound or not. Fortunately, there are two ways
to understand what is going on. Whenever you turn an encoder, its value will be displayed
in the OLED screen. For details of what is going on, check Utility>Controller>Knob (1-5).
Secondly, there is an option in the downloadable MIDI Control Center that enables you to
check what's going on:
• Open the MIDI Control Center
• Select 'MIDI console' in the View menu
• Activate Control mode in the KeyStep Pro.
If you now turn the main encoders, you will see their CC# messages (changing values)
displayed in the console window.

♪ : If you're a lucky owner of the Arturia Pigments software synth, you can map four of these
encoders to Pigment's four macro knobs.
8.1.2. CC# Patterns
A Pattern in the KeyStep Pro's Control Track runs in parallel with the normal Track Patterns
(sequences).
Is it possible to create 'empty' tracks containing control data only? Yes, it is. You could, for
example, assign one of the four tracks to 'play' control data exclusively and use it to control
parameters on an external synth, modular system or virtual instrument.
Each of the 16 Patterns in a Project can be used to stored control data in a CC# Pattern.
To load a CC# Pattern hold down the Pattern button and press one of the 16 step buttons.
Chaining Patterns is a way to create a linked series of CC# Patterns. You do this in the same
way that you chain sequencer Patterns.
Save CC# Patterns using SAVE + Pattern, just like saving normal sequencer Patterns.
In Control mode, everything is handled just like when working with normal sequencer
Patterns and tracks, except that there is no display of Pattern number and the Mute button
has no effect.
