Arpeggiator
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.
To create a new arpeggiator:
m Choose New > Arpeggiator (or use the New Arpeggiator key command.
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 Express must be running. (For technical reasons, the arpeggiator resets on cycle
jumps).
Typically, you would assign an arpeggiator to an Arrange 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.
The Arpeggiator Parameter Box
The Parameter box of an arpeggiator contains the following parameters:
Direction
Determines the direction of the arpeggiated chord. You can choose between the
following settings:
 Up: Lowest note to highest note.
 Down: Highest note to lowest note.
