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.
Important: Like the original instrument, Mercury-6's arpeggio section does not have a dedicated on/off control. Instead, arpeggio is considered a voice assign mode. With that in mind, the arpeggiator is enabled by clicking one of the pattern buttons (Up, Down, U/D, or Random). To disable the arpeggiator, select one of the assign modes in the adjacent Assign section (Solo, Uni, Poly 1, or Poly 2).
Rate- Sets the playback speed of arpeggiator sequences, from 1 to 22.5 Hz (with Sync disabled).
Sync- Engaging the Sync button locks arpeggio timing to master tempo. When engaged, the Rate 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 Mercury-6 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.
Pattern/Enable buttons- These buttons enable the arpeggiator and select the order in which the notes of chords are played.
Up- Notes play in order from lowest to highest.
Down- Notes play in order from highest to lower.
U/D (up and down)- This is the up and down mode, but like the original, has some (slightly) hidden functionality. When the U/D button is clicked, its LED will glow solidly, and the Up button will flash, indicating that notes will play up and then down. If the U/D button is clicked a second time, the LED still glows solidly, and the Down button will flash, indicating that notes will play down and then up.
Rnd (Random)- Notes are played in a random order.
