The modulation range is determined by the two arrows. The minimum amount of
modulation is indicated by the lower arrow. The upper arrow indicates the maximum
amount of modulation. The blue bar between the arrows shows the dynamic range of
this modulation. You can simultaneously adjust the modulation range and intensity by
dragging the blue bar and moving both arrows at once.
Tip: If you’re unfamiliar with these parameters, set the Cutoff to a low value, Resonance
to a high value, and move both of the ADSR via Vel arrows upwards. Constantly strike a
note on the keyboard while changing the arrows to discover how these parameters work.
Using the Envelope to Control the ES1 Amplifier
The AGateR, ADSR, and GateR buttons (in the Amplifier Parameter section) define which
of the ADSR envelope generator controls affect the amplifier envelope. All ADSR
parameters remain active for the filter.
Amplifier Envelope
Selector buttons
The letters A, D, S, and R refer to the attack, decay, sustain, and release phases of the
envelope (see Using the ES1 Envelope Parameters). Gate refers to a control signal used
in analog synthesizers that tells an envelope generator that a key is pressed. As long as
an analog synthesizer’s key is pressed, the gate signal maintains a constant voltage. When
Gate is used as a modulation source in the voltage-controlled amplifier (instead of the
envelope itself ), it creates an organ type envelope without any attack, decay, or release-an
even, sustained sound.
In the ES1, the Amplifier Envelope selector buttons have the following effect on played
notes:
AGateR: The Attack and Release sliders of the ADSR Envelope control the attack and
release phases of the sound. In-between these phases, the Gate control signal is used
to maintain a constant level, while the note is held. As soon as you release the key, the
release phase begins. The Decay and Sustain sliders of the ADSR Envelope have no
impact on the sound’s level.
ADSR: This is the standard operating mode of most synthesizers, where the level of the
sound over time is completely controlled by the ADSR Envelope.
