Change the keyboard mode
In Logic Pro, click the Poly, Mono, or Legato button.
In Mono mode, staccato playing retriggers the envelope generators every time a new
note is played. If you play in a legato style (play a new key while holding another),
the envelope generators are triggered only for the first note you play legato, then
they continue their curve until you release the last legato played key.
Legato mode is also monophonic, but with one difference:the envelope generators
are retriggered only if you play staccato—releasing each key before playing a new
key. If you play in a legato style, envelopes are not retriggered.
Note: On several monophonic synthesizers, the behavior in Legato mode is referred to
as single trigger, while Mono mode is referred to as multi trigger.
Use unison and voices controls in Logic Pro ES2
One of the great strengths of polyphonic analog synthesizers is unison—or stacked
voices—mode. Unison mode in polyphonic analog synthesizers is typically monophonic,
with all voices playing simultaneously when a single note is struck. Because the voices
of an analog synthesizer are never perfectly in tune, the result is an extremely fat chorus
effect with great sonic depth.
Use monophonic unison mode
1. In Logic Pro, click the Mono or Legato button, depending on the keyboard mode you
want to use. See Set the Logic Pro ES2 keyboard mode.
2. Click the Unison button.
The intensity of the unison effect depends on the number chosen in the Voices
parameter field. Increase the Voices value for a fatter sound. See Logic Pro ES2
global parameters overview.
The intensity of detuning (voice deviation) is set with the Analog parameter. See
Detune analog oscillators in Logic Pro ES2.
Use polyphonic unison mode
In Logic Pro, click the Poly and Unison buttons.
In poly/unison mode, each played note is effectively doubled—or, more correctly, the
polyphony value chosen with the Voices parameter is halved. These two voices are
heard when you trigger the note. Poly/unison has the same effect as setting the ES2 to
mono/unison (Voices=2), but you can play polyphonically.
Set the Logic Pro ES2 glide time
The Glide parameter (also known as portamento) sets the time it takes for the pitch of one
played note to travel to the pitch of another played note.
