Chapter 2 ES1 31
Use the ES1 modulation envelope
The modulation envelope can directly modulate the parameter chosen in the router. It
determines the time it takes for the modulation to fade in or fade out. At its center position (click
Full), modulation intensity is static—no fade-in or fade-out occurs. When set to its full value,
modulation intensity is at a constant level.
The modulation envelope allows you to set either a percussive type of decay envelope by
choosing low values or an attack type of envelope by choosing high values.
Modulation envelope parameters
•
Form slider and eld: Drag to set a fade-in (attack) or fade-out (decay) time for the modulation.
When set to the full position, the modulation envelope is turned o.
•
Int via Vel sliders: The top arrow sets the upper limit for the modulation envelope—for the
hardest keystrike (velocity = 127). The bottom arrow sets the lower limit—for the softest
keystrike (velocity = 1). The green bar between the arrows displays the impact of velocity
sensitivity on the intensity of the modulation envelope.
You can simultaneously adjust the modulation range and intensity by dragging the green
bar, thus moving both arrows at once. Note that as you do so, the arrows retain their relative
distance from each other.
Modulate a parameter with velocity
1 Select a modulation target, such as Pulse Width, from the right column of the router.
2 Set the Form slider to full, and adjust the Int via Vel parameter as needed.
This results in a velocity-sensitive modulation of the oscillator pulse width.
More interestingly, you can directly control the LFO level if you click the LFO Amp(litude) button
in the right column of the router.
Fade the LFO modulation in or out
m To fade in the LFO modulation: drag the Form slider to a positive value—toward attack. The higher
the value, the longer it takes for you to hear the modulation.
m To fade out the LFO modulation: drag the Form slider to a negative value—toward decay. The
lower the value—closer to decay—the shorter the fade-out time is.
LFO control with envelopes is most often used for delayed vibrato, a technique many
instrumentalists and singers employ to intonate longer notes.
Set up a delayed vibrato
1 Drag the Form slider to the right—toward attack.
2 Select Pitch as the LFO target in the left column of the router.
3 Use the Wave knob to select the triangular wave as the LFO waveform.
4 Drag the Rate eld to an LFO rate of about 5 Hz.
5 Drag the upper Int via Wheel arrow to a low value, and the lower arrow to 0.
