Arturia KeyStep - Controller / Sequencer - Manual (Page 18)

2.1.5. Sustain pedal
If you have a momentary footswitch, plug it into the Sustain jack on the rear panel. If it
works backward, disconnect KeyStep from its power source and then reconnect it. KeyStep
will sense the polarity of the pedal and it should work fine after that.
There are several configuration options for the Sustain pedal in the MIDI Control Center. See
chapter 8 [p.42] for information.
2.1.6. Oct - / Oct +
Pushing one of these buttons can transpose the keyboard by as much as four octaves up
or down. The farther from center the keyboard has been transposed, the faster the buttons
will flash.

After pressing one of the Octave buttons the transposition will not occur until the next note is played.
To reset the keyboard octave range back to center, press both buttons at the same time.
2.1.7. Factory reset
The Octave buttons are also used to reset all features of your KeyStep back to the factory
specifications. To do this:
• Unplug KeyStep from its power source
• Press the Oct- and Oct+ buttons and keep them down
• Plug KeyStep back into the power source
KeyStep will go through a longer version of its power-up LED sequence, which will end with
the Hold/Shift/Oct-/Oct+ buttons flashing in a circular pattern twice.
2.2. Select and play a sequence

Important: The sequencer will not run if the sync selection switches are set to something other than
Internal and no external clock is present.

Note: Chord mode has limited functionality in Seq mode. We’ll describe how the two work together
in section 3.1.1 [p.17] .
2.2.1. Sequencer / Arpeggiator toggle switch
To use the sequencer you must first set the Seq/Arp toggle switch to Seq. The position
marked Arp selects the arpeggiator, which is covered in section 2.3 [p.14]
