Arturia KeyStep Pro Keyboard with Advanced Sequencer and Arpeggiator - Manual (Page 42)

4.2.5.4. Control Mode
The Control button changes the function of the five main encoders. Instead of controlling
pitch, gate, velocity, etc. and the corresponding control voltages (CV) sent to the analog
outputs, in Control Mode they send MIDI control change (CC#) messages, enabling you to
control parameters of external hardware synths or Eurorack modules and, for example,
virtual instruments on your computer.
You enter Control Mode by pressing the Control button. When Control Mode is selected, the
five main encoders send CC# values. For an in-depth explanation of what CC# values are
and what you can use them for, please refer to Chapter 8 [p.137] . The CC# messages to be
sent can be edited using the OLED display in Utility>Controller and in the downloadable MIDI
Control Center.
4.2.6. Track Sections (4x)
The KeyStep Pro has four separate tracks, each of which has its own dedicated set of
buttons to give you instant control over important features.
The track controls are identical except for one button: Track 1 has a Drum button for the
drum sequencer, but Tracks 2, 3 and 4 each have an Arp button for the arpeggiators. The
track controls function as follows:
4.2.6.1. Track Selector
The Track Selector buttons (Track 1, Track 2, Track 3 or Track 4) let you select the currently
active track. The buttons of the active track light up, and the various controls of the KeyStep
Pro (keyboard, encoder knobs, step buttons, etc.) will only affect the currently selected track.
As you work with the KeyStep Pro, you will notice that there is a consistent color-coding
across the entire front panel. For example, Track 1 is green and when it is selected, all of the
Step Buttons and Keyboard LEDs will light up in green. Track 2 is orange and selecting it will
cause the Step Buttons and Keyboard LEDs to light up in orange. These color cues help you
to know what you are editing and to avoid accidentally changing parameters on the wrong
track.
