Modulation parameters
LFO parameters: Used to modulate other ES1 parameters. See Use the Logic Pro ES1
LFO.
Router: Enables you to choose the ES1 parameters that are modulated. See Use the
Logic Pro ES1 router.
Modulation Envelope: A dedicated modulation control source that can be used to
control various ES1 parameters, or it can be used to control the LFO level. See Use the
Logic Pro ES1 modulation envelope.
Use the Logic Pro ES1 router
The router determines the ES1 parameters ( targets) that are modulated by the LFO and by
the modulation envelope. The buttons in the left column set the target for LFO modulation.
The buttons in the right column set the target for the modulation envelope.
Router parameters
Pitch buttons: Modulate the pitch—the frequency—of the oscillators.
Pulse Width buttons: Modulate the pulse width of the pulse wave.
Mix buttons: Modulate the mix between the primary oscillator and the sub-oscillator.
Cutoff buttons: Modulate the cutoff frequency of the filter.
Resonance buttons: Modulate the resonance of the filter.
Volume buttons: Modulate the main volume.
Filter FMbutton (mod env only): Use the triangle waveform to modulate filter cutoff
frequency. This modulation can result in a pseudo-distortion of the sound, or it can
create metallic, FM-style sounds. The latter occurs when the only signal you can hear is
the self-oscillation of the resonating filter (see Overdrive the Logic Pro ES1 filter).
LFO Amp (mod env only): Modulate the overall amount of LFO modulation.
