Filter parameters: Located in the upper-middle section with the circular Filter area as
well as the Drive and Key scaling parameters, the filter is used to contour the waveforms
sent from the oscillators. See Logic Pro ES1 filter parameters overview.
Amplifier parameters: Located in the upper right, the amplifier parameters allow you to
fine-tune sound level behavior. See Logic Pro ES1 amplifier parameters.
Envelope parameters: Located to the right in the dark green/gray area, the ADSR sliders
are used to control both filter cutoff and the amplifier level over time. See Logic Pro ES1
envelope parameters overview.
Modulation parameters: Located to the left and middle in the dark green/gray area, the
modulation sources, modulation router, modulation envelope, and amplitude envelope
are used to modulate the sound in a number of ways. See Logic Pro ES1 modulation
parameters overview.
ES1 oscillator parameters
Logic Pro ES1 oscillator parameters overview
ES1 includes a primary oscillator and a sub-oscillator. The primary oscillator generates
a waveform that is sent to other parts of the synthesizer for processing or manipulation.
The sub-oscillator generates a secondary waveform one or two octaves below that of the
primary oscillator.
Oscillator parameters
Wave knob: Select the waveform of the primary oscillator, which is responsible for the
basic color of the tone. See Logic Pro ES1 oscillator waveforms.
Mix slider: Set the level relationship between the primary and sub-oscillator signals.
(When the sub-oscillator is switched off, its output is completely removed from the
signal path.)
Sub knob: Generate square, pulse, and white-noise waveforms with the sub-oscillator.
The sub-oscillator also allows you to route a side chain signal through the ES1
synthesizer engine. See Use the Logic Pro ES1 sub-oscillator.
2’, 4’, 8, 16’, and 32’ buttons: Transpose the pitch of the oscillators up or down by
octaves. The lowest setting is 32feet and the highest is 2feet. The use of the term feet
to determine octaves comes from the measurements of organ pipe lengths. The longer
and wider the pipe, the deeper the tone.
