• Sustain slider: Set the signal level (the sustain level).
• Release slider: Set the time it takes for the signal to fall from the sustain level to a level
of zero.
• Volume knob: Set the overall output level.
• Velo Volume knob: Set the amount (depth) of velocity sensitivity to incoming MIDI
note events. At higher values, each note is louder if struck harder. At lower values, the
dynamic response is reduced, so that there is little difference when you play a note
pianissimo (soft) or forte (loud/hard).
• VCA Mode buttons (Controls view): Click ADSR to control the amplifier with the ADSR
envelope generator. Click Gate to output a constant organ-like tone when a key is
played.
Use the Logic Pro ESP effects processor
ESP offers integrated stereo chorus and overdrive effects. These are based on similar
effects processors found in the synthesizers of the 1980s that ESP emulates.
ESP effect parameters
• Chorus knob: Set the intensity (depth) of the integrated chorus effect.
• Overdrive knob: Set the overdrive/distortion level of the synthesizer output.
Important: To avoid hurting your ears or damaging your speakers, consider turning
down the Volume level before setting Overdrive to a high value; then turn it up gradually.
Logic Pro ESP extended parameters
ESP offers three additional parameters that are accessed by clicking the disclosure
triangle at the lower left of the interface.
• Pos. Bender Range slider: Set the upward pitch bend range in semitone steps. This
allows you to use the pitch bend controller of your keyboard to bend the ESP pitch.
• Neg. Bender Range slider: The default Neg. Bender Range value is Pos PB (positive
pitch bend). In essence, this means that only positive pitch bend is available. Set the
downward pitch bend range in semitone steps, by up to 2octaves (a value of 24).
• Tune slider: Tune the instrument in cents. One cent is 1/100th of a semitone.
