If Key is set to maximum, the filter follows the pitch, resulting in a constant relationship
between cutoff frequency and pitch. This mirrors the properties of many acoustic
instruments where higher notes sound both brighter in tone and higher in pitch.
ADSR via Vel slider: Determines how note velocity affects the filter cutoff frequency
modulation—caused by the envelope generator (see Using the ES1 Envelope
Parameters).
Driving the ES1 Filter to Self-Oscillation
You can make the ES1 filter output a sine wave by following the steps below. This will
allow you to play the filter-generated sine wave with the keyboard.
To output a sine wave from the filter
1 Switch the Sub knob to OFF.
2 Move the Mix slider to the very bottom (Sub).
3 Turn the Resonance knob to the maximum position.
Using the ES1 Amplifier Parameters
The parameters in the ES1 Amplifier section allow you to fine-tune the behavior of your
sound’s level. These are separate from the global Out Level parameter, found on the strip
at the bottom of the interface, and which acts as the ES 1’s master volume (see Adjusting
Global ES1 Parameters).
Level via Vel slider: Determines how note velocity affects the synthesizer level-set by
the global Out Level parameter. The sliders upper arrow indicates the level when you
play fortissimo. The lower arrow indicates the level when you play pianissimo
(velocity = 1). The greater the distance between the arrows (indicated by the blue bar),
the more the volume is affected by incoming velocity messages. You can simultaneously
adjust the modulation range and intensity by dragging the blue bar-between the
arrows-and moving both arrows at once.
