Arpeggiator objects
Arpeggiator objects overview
An arpeggiator object turns chords into arpeggios. It plays the currently held notes—
individually—in a selectable pattern (up, down, random, and so on), and at a selectable speed
that ranges between whole notes and 768th notes.
An arpeggiator features parameters for direction, velocity, speed (Resolution), note length, start
quantize (Snap), repeats, octaves, and velocity offset (Crescendo). All parameters can be MIDI
controlled in real time, which adds immensely to its versatility.
To use an arpeggiator object, you must place it in the MIDI signal path, and Logic Pro must be
open. (For technical reasons, the arpeggiator resets on cycle jumps.)
Typically, you would assign an arpeggiator to a track, and cable its output to an instrument. You
can, of course, insert it where needed in the MIDI signal path.
Once set up, you can use the arpeggiator with live MIDI input, or for MIDI region playback. You
can also record the output of the arpeggiator by cabling it into the Sequencer Input object. If
you do this, be sure you either record to a no output track, or break the arpeggiator’s connection
to a MIDI output.
