Arp

This menu lets you determine how an arp, or arpeggio is played in time with the beat.

Type

Type is the shape of the walk or which note comes next.

• Up — ascending, lowest to highest, then back to the bottom. The default, and the one that sits under almost anything.
• Down — descending, highest to lowest.
• Mirror — up and then back down, turning around at each end rather than jumping.
• Alt — alternates between the outer and inner notes of the chord for a wider, less predictable figure.
• Random — picks a note at each step. Good for shimmer under a pad; not for a part anyone has to follow.

Speed

Speed is how fast the figure steps, in notes per beat. It follows the song's tempo, so the arpeggio stays locked to everything else the AuxDock is playing.

• Quarter — one note per beat.
• Eighth — two per beat. The default.
• 16th — four per beat.
• Triplet — three per beat.
• Sextuplet — six per beat.

Type and Speed are independent, so any shape can run at any rate. Triplet and Sextuplet are the fastest way to make an arpeggio stop sounding like a grid. Against a straight-eighths song they give the part a rolling feel that straight subdivisions can't.
