4.12. Arpeggiator
KeyLab Essential includes a fun and flexible Arpeggiator fashioned after those in classic
synths, letting you craft rolling, percolating patterns out of held chords.
An arpeggiator is included in many synthesizer models. It takes chords played on the
keyboard and converts them into arpeggios. An arpeggiator usually includes controls for
Speed, Range (in octaves), Mode (if the pattern moves up, down, or up/down etc.), and Hold
(continues playing the arpeggio after the keys have been released).
Arpeggiator information is transmitted as MIDI data over the USB-C port and/or 5-pin MIDI
output, depending on which are selected in your host software’s MIDI settings.
4.12.1. Activating and deactivating the Arpeggiator
To turn the arpeggiator on and off, press the Arpeggio button. The KeyLab Essential display
will momentarily reflect its state:
! The Arpeggiator is triggered only by the keyboard, not the pads. Also, when the Arpeggiator is
activated, the pads can still be used to trigger sounds.
