Chorus field: Choose a classic stereo chorus effect, an ensemble effect, or disable the
effects processor.
Off disables the built-in chorus circuit.
C1 is a typical chorus effect.
C2 is a variation of C1 and is characterized by a stronger modulation.
Ens(emble) uses a more complex modulation routing, creating a fuller and richer
sound.
Midi Mode pop-up menu (Extended Parameters area): Determine how ES1 responds to
MIDI controllers. Choose either Off or Full Remote.
ES1 filter parameters
Logic Pro ES1 filter parameters overview
This section outlines the ES1 filter parameters.
Filter parameters
Cutoff slider: Set the cutoff frequency of the lowpass filter.
Resonance slider: Cut or boost the portions of the signal that surround the frequency
defined by the Cutoff parameter. Boost can be set so intensively that the filter begins to
oscillate by itself (see Overdrive the Logic Pro ES1 filter).
Tip: You can simultaneously adjust the cutoff frequency and resonance parameters
by dragging vertically (cutoff) or horizontally (resonance) on the word Filter, found in
the center of the black circle.
Slope buttons: The lowpass filter offers four different slopes of band rejection above
the cutoff frequency. Click one of the buttons to choose a slope (amount of rejection,
expressed in decibels (dB) per octave):
24dB classic: Mimics the behavior of a Moog filter. Increase the Resonance
parameter value to reduce the low end of the signal.
24dB fat: Compensates for the reduction of low frequency content caused by high
Resonance values. This resembles the behavior of an Oberheim filter.
12dB: Provides a soft, smooth sound that is reminiscent of the early Oberheim SEM
synthesizer.
18dB: Resembles the filter sound of the Roland TB-303.
