Live mode parameters
•
Rest button: Click to insert a rest at the current arpeggiator step position. A position
identication number is assigned to the rest, ensuring that its rhythmic position (step number)
within the arpeggio is retained, even when dierent note order presets are chosen.
Note: Rests can only be added while building the arpeggio, which means that at least one
key must be held if you want to add a rest. Once all keys are released, the Arpeggiator acts
in accordance with the rules of the set Latch mode and expects to receive a MIDI note for
transposition and so on. In Latch Add mode, this restriction does not apply because it allows
you to add MIDI notes, rests, ties, and chords after all keys are released.
•
Tie button: Click to insert a tie at the current arpeggiator step position. A position identication
number is assigned to the tie, ensuring that its rhythmic position (step number) within the
arpeggio is retained, even when dierent note order presets are chosen.
•
Chord button: Click to insert a chord at the current arpeggiator step position. When the
arpeggiator encounters a chord step, it simultaneously plays all notes, including their unique
velocities, currently in memory (latched or held). A position identication number is assigned
to the chord, ensuring that its rhythmic position (step number) within the arpeggio is retained,
even when dierent note order presets are chosen.
Arpeggiator Grid mode
The grid consists of 16 steps. Each step controls the step velocity as well as its rest, tie, and chord
status. In addition, a cycle length can be set. The current grid pattern is automatically saved with
the Logic project. You can also save and load your own or factory grid patterns. The Arpeggiator
plug-in assigns incremental position identication numbers to each note in the order they
were received, regardless of the initially selected note order preset. These position identication
numbers are used to “lock” an event, such as a note, a rest, or a tie to a particular step.
Grid mode parameters
•
Step on/o buttons: Click to turn each of the 16 available steps on or o.
•
If a step is turned on: An arpeggiator note is played at the respective grid position.
•
If a step is turned o: The grid position is silent and is perceived as a rest.
Note: To ensure the integrity of the arpeggio, the note that would have been played—if the
step had been active—is moved to the next active grid position.
•
Velocity bars: Drag the velocity bar vertically to set the velocity for each active step. Where
multiple velocity bars exist, click above them to draw in the velocity of several steps.
Drag the velocity bar toward the right to overlap the next step, thus tying it to that step. If the
step to the right is a rest (an inactive step) this step is automatically turned on to create the
tie. A step can be tied to multiple steps in a row. The original velocity values of tied steps are
replaced by the velocity of the rst step they are tied to, indicated graphically by the velocity
bar extending over all tied steps.
