Logic Pro ES1 amplifier parameters
The parameters in the ES1 Amplifier section allow you to fine-tune sound level behavior.
These are separate from the global Out Level parameter, which acts as the ES1 master
volume control. See Logic Pro ES1 global parameters.
Amplifier parameters
Level via Vel slider: Determine how note velocity affects the synthesizer level. The
greater the distance between the arrows (indicated by the blue bar), the more the
volume is affected by incoming velocity messages.
Drag the upper arrow to set the level when you play hard (velocity=127).
Drag the lower arrow to set the level when you play softly (velocity=1).
To simultaneously adjust the modulation range and intensity, drag the blue bar—
between the arrows—and move both arrows at once.
Amplifier envelope selector buttons: Determine the ADSR envelope generator used for
control of the amplifier envelope. See Logic Pro ES1 envelope parameters overview.
ES1 envelope parameters
Logic Pro ES1 envelope parameters overview
ES1 provides an attack, decay, sustain, and release (ADSR) envelope that can shape filter
cutoff and the level of the sound over time.
Envelope parameters
Attack slider: Set the time it takes for the envelope to reach the initial desired level.
Decay slider: Set the time it takes for the envelope to fall to the sustain level, following
the initial attack time.
