Arpeggiator control parameters
The control parameters start and stop the Arpeggiator and determine the latching behavior. You
can also capture a live arpeggio as a MIDI region.
Control parameters
•
Play button: Click to start or stop arpeggiated playback of note input from a MIDI keyboard
or a MIDI region. The Play button is lit when in play mode. When the Arpeggiator plug-in is
stopped, incoming MIDI notes are passed through, and the settings of the split and remote
keyboard parameters are retained. See Arpeggiator keyboard parameters.
•
When Logic Pro is in play mode: The arpeggio starts playing whenever the Arpeggiator Play
button is on, including when the plug-in is rst inserted. Arpeggio playback is linked to the
Logic song position.
•
When Logic Pro is stopped: Arpeggio playback stops. Incoming MIDI notes are passed
through, and keyboard split and remote settings are retained.
Note: You can click the Arpeggiator Play button while Logic Pro is stopped to begin arpeggio
playback from the rst step in the arpeggio.
•
Capture live performance button: Click the button, then drag the playing arpeggio to any
software instrument track. The currently playing arpeggio pattern is placed as a MIDI region at
the target position.
•
Latch button: Click to turn Latch mode on or o. This enables an arpeggio to run without the
need for you to hold down keys. Latch mode behavior is determined with the Latch mode
pop-up menu.
•
Latch mode pop-up menu: Choose a Latch mode:
•
Reset: The rst key played clears the currently latched notes.
•
Transpose: Play a single key to transpose the arpeggio relative to the note value of the
pressed key and the lowest arpeggiated note.
Note: Pressing more than one key simultaneously clears currently latched notes and starts a
new arpeggio.
•
Gated Transpose: This option is the same as Transpose Latch mode with the dierence that
the arpeggio only plays while a key is pressed. As soon as the key is released, the arpeggio
is muted.
•
Add: Play keys—one by one, or simultaneously as a chord—to add them to the latched
arpeggio. You can play the same key multiple times and the note repeats the number of
times it is struck.
•
Add Temporarily: This option is the same as Add Latch mode except that played notes are
added to the latched arpeggio only while held. When a temporarily added key is released, it
is removed from the arpeggio.
•
Through: All incoming MIDI notes are passed through the Arpeggiator plug-in, enabling you
to play along with a latched arpeggio.
•
Delete Last button: Click to delete the last event—a note, rest, or tie—that was added to
the arpeggio.
Note: Each event is allocated a unique position identication number and the “last” event has
the highest position identication number.
