ARTURIA – KeyStep – USER’S MANUAL 13
2.2.1.1 Seq / Arp toggle switch
When this switch is set to Seq a sequence can be played or recorded. The controls in this
section select which sequence is active and the time division at which it will be played
back.
When the switch is set to Arp the controls select the pattern and the time division for the
arpeggiator.
2.2.1.2 Seq / Arp modes
The function of the Seq / Arp Mode encoder changes depending on which mode is
selected. In sequencer mode it selects which of the eight sequences is active. In
arpeggiator mode it selects which pattern will be used to play back the notes you hold on
the keyboard.
For a full explanation of these features, see chapter 6 (Projects) and chapter 10 (Control
Mode).
2.2.1.3 Time Division
The Time Div encoder determines the rhythmic value of the active sequence or arpeggio.
Eight different settings are available.
We’ll go into this in greater detail in chapter 3.
2.2.1.4 Rate
Use the Rate knob to control the tempo of the sequence or arpeggio. The Tap button can
also be used. The tempo can be set between 30-240 bpm (beats per minute).
The MIDI Control Center allows you to choose how the Rate knob responds when it is
turned: either immediately (Jump mode) or after you pass through the current value
(Pick-up mode). See chapter 10 to learn about the MIDI Control Center.
2.2.2 Tap Tempo / Rest / Tie
The Tap button allows you to set the tempo of the active sequence or
arpeggio “on the fly”. All you have to do is tap it in time with the music. The
number of taps it takes to adjust the tempo can be defined in the MIDI
Control Center.
This button is also used to enter rests or to tie two notes together when
creating a sequence. See section 5.2.1 for information about this.
2.2.3 Transport section
The Transport buttons control the sequencer, the arpeggiator, and external MIDI devices
using MIDI Machine Control. But they also can send other MIDI messages if your DAW
does not respond to MMC commands. Use the MIDI Control Center to make changes.
All three buttons are active in sequencer mode, while only Play/Pause and Stop are used
with the arpeggiator.
