ES1 modulation
ES1 modulation parameters overview
ES1 oers a number of simple yet exible modulation routing options. You use modulation to
add animation to your sound over time, making it more interesting, lively, or realistic. A good
example of this type of sonic animation is the vibrato used by orchestral string players.

Modulation parameters
LFO parameters: Used to modulate other ES1 parameters. See Use the ES1 LFO on page 30.
Router: Enables you to choose the ES1 parameters that are modulated. See Use the ES1
router on page 29.
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 ES1 modulation
envelope on page 31.
Use the 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.

buttons
Router parameters
Pitch buttons: Click to modulate the pitch—the frequency—of the oscillators.
Pulse Width buttons: Click to modulate the pulse width of the pulse wave.
Mix buttons: Click to modulate the mix between the primary oscillator and the sub-oscillator.
Cuto buttons: Click to modulate the cuto frequency of the lter.
Resonance buttons: Click to modulate the resonance of the lter.
Volume buttons: Click to modulate the main volume.
Filter FM button (modulation envelope only): Click to use the triangle wave of the oscillator
to modulate lter cuto 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 lter (see Drive the ES1 lter to self-oscillate on
page 25).
LFO Amp (modulation envelope only): Click to modulate the overall amount of LFO modulation.
