ES2 global parameters
Logic Pro ES2 global parameters overview
The ES2 global parameters affect the overall instrument sound produced by ES2. You can
find global parameters to the left of the oscillators and above the filter and output sections.
The Volume knob is at the lower right.
Global parameters
Keyboard Mode buttons: Switch ES2 between polyphonic, monophonic, and legato
behaviors. See Set the Logic Pro ES2 keyboard mode.
Unison button: Turn unison mode on or off. See Use unison and voices controls in Logic
Pro ES2.
Voices field: Set the maximum number of notes that can be played simultaneously.
Glide knob: Set the time it takes for the pitch of a played note to slide to the pitch of the
following played note. See Set the Logic Pro ES2 glide time.
Bend Range fields: Define the upward and downward pitch bend range. See Set the
Logic Pro ES2 pitch bend range.
Tune field: Set the overall instrument pitch in cents. 100 cents equals a semitone step.
At a value of 0c (zero cents), the central A key is tuned to 440Hz, or concert pitch.
Analog knob: Rotate to randomly alter the pitch of each note and the filter cutoff
frequency. See Detune analog oscillators in Logic Pro ES2.
Constant Beat Detuning pop-up menu: Detuned oscillators periodically beat against
each other at a certain frequency. Use CBD to set the beating frequency between low
and high notes or to retain a constant beating.
Oscillator Start pop-up menu: Choose “free,” “soft,” or “hard” from the Osc(illator) Start
pop-up menu. See Set Logic Pro ES2oscillator start points.
Volume knob: Set the overall instrument output level.

A polyphonic instrument, such as an organ or a piano, allows several notes to be played
simultaneously. Many older analog synthesizers are monophonic, which means that only
one note can be played at a time, much like a brass or reed instrument. This shouldn’t
be viewed as a disadvantage; instead, it allows playing styles that are not possible with
polyphonic instruments.
