Arturia KeyStep Pro Keyboard with Advanced Sequencer and Arpeggiator - Manual (Page 69)

5. MAKING TRACKS
In this chapter, we'll have a look at the process of creating (drum) sequences and arpeggios.
What's the use of having tracks if you have nothing to fill them with?
5.1. Sequencer / Arpeggiator (or Drum) Tracks
The KeyStep Pro has four Tracks, each with its own independent sequencer or arpeggiator.
Sequencer Arpeggiator Drum Sequencer
Track 1 Yes No Yes
Track 2 Yes Yes No
Track 3 Yes Yes No
Track 4 Yes Yes No
Each track has a pair of buttons labelled Seq and Arp (or Seq and Drum on Track 1). These
buttons let you set the functionality for their associated track. The currently selected option
is lit up and only one mode can be active at any time.
5.2. The Three Arpeggiators
One of the unique features of the KeyStep Pro is that it has three arpeggiators. What
makes it even more unique is that these arpeggiators can run in different scales and time
signatures simultaneously!
5.2.1. What is an Arpeggiator?
An arpeggiator breaks up a chord into individual notes: hold down a chord on the keyboard
and the arpeggiator will play the notes in the chord one by one at equal time intervals. You
can keep adding notes to the arpeggio: simply holding down more keys will add them to the
arpeggio. If you happen to have 16 fingers you can use all of them to create a maximum-
length arpeggio, but a better way to extend arpeggios is to make use of the HOLD key. We'll
explain this in the next sub-section.
To activate the arpeggiator, select a track with an arpeggiator (Track 2, 3 or 4) and press the
Arp button. It lights up in white to show that Arpeggio mode is currently active on that track.
Now hold a chord and hear the arpeggio play.

♪ : Pressing 'Play' is optional. However, if you want to record your arpeggio in the sequencer on the
same track, pressing 'Play' is required.
