An arpeggiator is basically a step sequencer that plays each note of a chord individually in an ascending or descending pattern across one or more octaves.
Pattern buttons- These buttons enable the arpeggiator and select the order in which the notes of chords are played.
Off- Arpeggio is disabled. You knew that.
Up- Notes play in order from lowest to highest.
Down- Notes play in order from highest to lower.
Up/Down- Notes play from lowest to highest and back down from highest to lowest.
Rnd (Random)- Notes are played in a random order.
Speed- Sets the playback speed of arpeggiator sequences, from 0.25 to 30 Hz (with Sync disabled).
Sync- Engaging the Sync button locks arpeggio timing to master tempo. When engaged, the Speed knob snaps to note values ranging from 1/64th note triplet to 8 beats. Sync mode locks to the tempo in the top toolbar when using the Atomika standalone version or the current project tempo when the plug-in version is used in a DAW.
Range buttons- Selects how many octaves the pattern will play before repeating. Only one button can be pressed at any time.
