Arturia KeyStep 37 MIDI Keyboard Controller and Sequencer - Manual (Page 24)

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, turn the KeyStep37 off then on again. KeyStep 37 will now 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 9 [p.74] 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 your KeyStep 37 back to the factory specifications.
To do this:
• Turn off KeyStep 37
• Press the Oct- and Oct+ buttons and keep them down
• Turn the KeyStep 37 back on and watch it display 'rST'
