ADSR via Vel
The main envelope generator (ADSR) modulates the cutoff frequency over the duration
of a note. The intensity of this modulation can be set to positive or negative values, and
can respond to velocity information. If you play pianissimo (Velocity = 1), the
modulation will take place as indicated by the lower arrow. If you strike with the
hardest fortissimo (Velocity = 127), the modulation will take place as indicated by the
upper arrow. The blue bar between the arrows shows the dynamics of this modulation.
You can adjust the modulation range and intensity simultaneously by grabbing the bar
and moving both arrows at once. Note that as you do so, they retain their relative
distance from one another.
Level via Vel
The upper arrow works like a main volume control for the synthesizer. The greater the
distance from the lower arrow (indicated by the blue bars), the more the volume is
affected by incoming velocity messages. The lower arrow indicates the level when you
play pianissimo (velocity =1). You can adjust the modulation range and intensity
simultaneously by grabbing the bar and moving both arrows at once. Note that as you
do so, they retain their relative distance from one another. In order to retain the
maximum possible resolution for velocity sensitivity, even when set to a low volume,
the ES1 has an additional Out Level parameter—available in the Controls view.
Amplifier Envelope Selector
The AGateR, ADSR, and GateR buttons define which of the ADSR envelope generator
controls have an effect on the amplifier envelope.
 AGateR: Activates the attack and release time controls, but allows the level to remain
constant between the time the peak level is reached, and the release of the key—
regardless of the decay and sustain settings.
 ADSR: Activates all controls for the amplifier section.
 GateR: Sets the attack time for the amplifier section to zero, with only the release
control still having an effect on the envelope level.
