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 the MIDI output.
Arpeggiator Parameters
The arpeggiator features the following parameters (the numbers in parentheses are
Control Base offsets—see below):
Direction (
+
0)
The direction of the arpeggiated chord:
• Up: Lowest note to highest note
• Down: Highest note to lowest note
• UpDn: Up and down—highest and lowest notes repeat
• Auto: Up or down depending on whether the second chord note arrived before or
after the first chord note
• UpD2: Up and down—highest and lowest notes don’t repeat
• Rand: Notes play in random order
• All: All notes play at once (useful when repeat is on)
Vel (
+
1)
Velocity values of the arpeggiated notes.
• 1 to 127: Fixed velocities,
• Orig: the velocities of the recorded notes are retained,
• Rand: random velocities between 1 and the original value.
Lim (Low:
+
2, High:
+
3)
This is where you can define the pitch range (between C-2 and G8) for the chord
arpeggiation. Any chord notes outside this range are passed directly to the output. This
is useful when you want to solo above, or play a bass line below an arpeggiated chord.
Res (
+
4)
This is where you set the rhythmic note value (the speed in note divisions) of the
arpeggio via a pull-down menu. None = arpeggiator switched off.
Len (
+
5)
This is where you define the length of the arpeggiated notes. The Orig setting retains
the lengths of recorded notes.
Snap to (
+
6)
Unless this value is set to None, the arpeggiator will wait for Logic’s transport to reach
the next indicated note division before starting the arpeggio. This is useful for
rhythmically synchronizing the arpeggio with other MIDI data.
