Arpeggiator
While using the arpeggiator, playing a chord causes the individual notes of the chord
to play one at a time in a set order and repeat until the chord is released. The
arpeggiator affects notes being played on the keyboard only.
To enable or disable the arpeggiator, press Arp On/Off. This button controls the
operation of the arpeggiator. The button’s LED on/off state will indicate the
Arpeggiator status. This button has a dual function:
• Press the Arp On/Off button once to activate or deactivate the arpeggiator.
When the button is lit, the arpeggiator is engaged. Press the button again to turn
the arpeggiator off.
• The settings for the arpeggiator can be changed using the Arp On/Off button in
conjunction with the keyboard keys. When the Arp On/Off button is pressed and
held, the keyboard keys with white text labeled above them can be used to
change the parameters of the Arpeggiator.
When the arpeggiator is on, Note On and Note Off messages will only be sent from
the arpeggiator and will not be sent when a key is actually pressed. All of the
pressed keys will tell the arpeggiator which notes to play. If the arpeggiator is
latched, then keys that are released will stay in the arpeggiator. When the
Arpeggiator is turned off, then all notes are released from the arpeggiator.
To momentarily latch the active arpeggiator, press and hold the Sustain button.
When the button is released, the Arpeggiator will disengage latch.

8
The rate of the arpeggiator is based on the current tempo and time division settings.
To set the tempo, press Tap Tempo several times at the desired rate. The
arpeggiator will automatically detect the new tempo.
Important: Tap Tempo does not work when LPK25 mk2 is externally synced.
To set the time division, press and hold Arp On/Off, and press one of these keys
on the keyboard:
1/4(quarter notes) 1/16 (sixteenth notes)
1/4T (quarter-note triplets) 1/16T (sixteenth-note triplets)
1/8(eighth notes) 1/32 (thirty-second notes)
1/8T (eighth-note triplets) 1/32T (thirty-second-note triplets)
The arpeggiation type determines the order in which the notes of a chord play,
whether they ascend or descend, etc.
To set the arpeggiation type, press and hold Arp On/Off, and press one of these
keys on the keyboard:
• Up: Notes arpeggiate from the lowest note up to the highest note.
• Down: Notes arpeggiate from the highest note down to the lowest note.
• Excl (Exclusive):Notes arpeggiate from the lowest to the highest note and
back down. Lowest and highest notes are not retriggered when the arpeggio
changes direction.
• Incl (Inclusive):Notes arpeggiate from the lowest to the highest note and back
down. Lowest and highest notes are retriggered when the arpeggio changes
direction.
• Order: Notes will be repeated in the same order in which their keys were
pressed.
• Rand (Random):Plays the held notes in random selection.

9
The arpeggiation range determines the number of octaves across which the arpeggio
will play. After the arpeggio plays at the highest octave in the range, the arpeggio will
repeat from the lowest octave.
To set the arpeggiation range, press and hold Arp On/Off, and press Arp 1, 2, 3,
or 4.
You can set the arpeggiator to follow the tempo of LPK25 mk2’s internal MIDI clock
or the external tempo of the project in your digital audio workstation (DAW).
Press and hold Arp On/Off, and press the Latch key on the keyboard. When the
Arpeggiator is on and Latch is enabled, you can press a combination of keys on the
keyboard and the Arpeggiator will continue to arpeggiate these notes even after you
release the keys. Pressing a new combination of keys will start a new arpeggiation.
To set whether the arpeggiator is internally or externally synced, press and hold
Arp On/Off, and press the Sync key on the keyboard.
To set the Swing value, press and hold Arp On/Off, and press one of these Swings
keys: 50%, 55%, 59%, 61%, or 64%.
