Sculpture amplitude envelope in Logic Pro for iPad
The parameters discussed in this section apply on a per-voice basis. This is a straightforward ADSR envelope that scales the pickup signals before passing them on to the Waveshaper and filter.
The positioning of the amplitude envelope at this point in the signal path produces more natural-sounding results because you can control signal levels before sending them to the Waveshaper (if used). The Waveshaper can have a significant impact on the spectral content of the sound, which can lead to synthetic-sounding results.
Amplitude envelope parameters
Attack Soft/Hard sliders and fields: Set the attack time for a note played at minimum velocity with the left slider (Soft). Set the attack time for a note played at maximum velocity with the right slider (Hard).
Important: The attack time parameters of the amplitude envelope have a major impact on the way a single note is retriggered. When both Attack Soft and Hard are set to a value of 0, the vibrating string is retriggered. If either of these parameters is set to a value above 0, a new note is triggered. Sonically, the retriggering of a vibrating string results in different harmonics being heard during the attack phase.
Decay slider and field: Set the time it takes for the signal to fall to the sustain level, following the initial strike/attack time.
Sustain slider and field: Set the sustain level. The sustain level is held until the key is released.
Release slider and field: Set the time it takes for the signal to fall from the sustain level to a level of 0. Short Release values help to reduce CPU load because the voice is no longer processed after the release phase has completed.
Note: Even with long decay and release times, the sound may decay quickly. This can be caused by high Inner or Media Loss values in the string material section or by objects (2 or 3) that are used to damp the string.
