Always: If the Num value is 1, a trigger is generated at the start of each legato group,
and portamento occurs at the start of every note. For all other Num values, a trigger
is generated at the start of every note, and portamento occurs at the start of every
note.
Retrigger: A trigger is generated at the start of every note, and portamento occurs at
the start of every note.
Legato: If the Num value is 1, a trigger is generated at the start of each legato group,
and portamento occurs at the start of each legato group. For all other Num values,
behavior is unchanged when you play single notes. When you play a chord, each
note of the chord is triggered individually.
Num(ber of voices) pop-up menu: Set the maximum polyphony of a preset (up to 32
voices) when used globally, or maximum polyphony per source. A value of 1 results in a
monophonic preset or source.
Tip: Aim for the lowest possible polyphony value for the preset because this helps to
reduce CPU load.
Voice Priority pop-up menu: Choose the Newest (last played), Oldest (first played),
Lowest or Highest (pitch) note to be prioritized when polyphony is exceeded. This
parameter can be used globally or per source.
Rate/Time buttons: The portamento (glide) mode can be set to Rate or Time. This
parameter can be used globally or per source.
Rate: Alchemy glides from note to note at a fixed rate set with the Glide knob. Longer
glides require more time. Shown as a percentage of the overall envelope length.
Time: Alchemy glides from note to note over a fixed amount of time (in msec) set
with the Glide knob. Longer glides occur at a faster rate.
Glide knob: Set the portamento rate or time. Glide causes slides from one note pitch to
the next. This parameter can be used globally or per source.
Pitch bend Up/Down pop-up menus: Set the maximum range for upward and downward
pitch bend modulation, typically performed with your keyboard pitch wheel. Can be set
globally or per source.
Note: Individual sources can be set to respond to pitch bend or to ignore it. This is
determined with the Keyscale parameter on each source subpage. Pitch bend is also
available as a modulator, allowing further control over the pitch bend response of each
source. See Logic Pro Alchemy source subpage controls.
