An Arpeggiator receives incoming MIDI notes, and outputs a sequenced pattern of notes based on a defined set of rules. Similar in concept to a step sequencer, an Arpeggiator has a number of differences that set it apart. Like a step sequencer, an Arpeggiator allows you to create and transpose a pattern, but it also interacts directly with the chords and intervals that you play from the keyboard.

Omnisphere’s Arpeggiator has multiple modes, trigger-types, and clock rates, a variable-length 32-step Pattern Programmer, and features the innovative Groove Lock feature that synchronizes the Arpeggiator with Stylus RMX grooves (or any standard MIDI file).

Each Part in Omnisphere can have its own Arpeggiator, each with its own unique pattern settings. This means that up to eight Arpeggiators can be running simultaneously, which is especially powerful when using Stack and Live Modes.

There are many Arpeggiator presets available to help get you started exploring the Arpeggiator’s capabilities. Selecting the different Arpeggiator presets will allow you to check out some examples of the kinds of arpeggio patterns that can be created. Arpeggio patterns that you create or modify can be saved as presets for later use.
