• Sustain slider: Set the sustain level, which is held until the key is released.
• Release slider: Set the time it takes the envelope to fall from the sustain level to a level
of 0.
Logic Pro ES1 cutoff envelope modulation
The envelope generator modulates the filter cutoff frequency over the course of a note
duration. The modulation intensity and response to velocity information is set with the
ADSR via Vel slider in the Filter section.
Set the modulation range with the two arrows on the ADSR via Vel slider.
• The lower arrow indicates the minimum amount of modulation.
• 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.
Tip: If you’re unfamiliar with these parameters, set the Cutoff parameter to a low value,
Resonance to a high value, and move both ADSR via Vel arrows upward. Constantly strike a
note on the keyboard while changing the arrows to learn how these parameters work.
Logic Pro ES1 amplifier envelope modulation
The AGateR, ADSR, and GateR buttons in the Amplifier section determine which of the
ADSR envelope controls affect the amplifier envelope. All ADSR parameters remain active
for the filter.
The letters A, D, S, and R refer to the attack, decay, sustain, and release phases of the
envelope (see Logic Pro ES1 envelope parameters overview).
