AMPLITUDE ENVELOPE SECTION
Preattack: The Pre-attack level is adjusted with percentage numbers (0-100).
It is the very first point of a sample’s ADSR envelope and sets the initial volume level of the attack. For example, a Preattack level of 50.00 sets the beginning of the attack envelope to half the potential volume of the sample. This allows for a sample to begin at any level from silent to full volume.
Attack: The amplitude Attack time is measured in seconds (0-10). This value sets the amount of time that it takes for a sustained sample attack to reach its full volume. For most acoustic instrument samples, this time will range from zero to any value yielding a natural sounding attack. However, extreme settings can be used for musical effects like crescendos.
Decay1: The Decay1 time is measured in seconds (0-60).This parameter defines the amount of time it takes to decay from the peak level of the attack down to the sustain level.
Sustain: The Sustain level is adjusted with percentage numbers. (0-100).After the first decay completes, the sample will sustain for a period of time dependant on the Decay2 setting. The Sustain setting determines the volume level of the sustain portion of the ADSR that occurs between Decay1 and Decay2.
Hold: If a sample has a loop point, the Hold function will prevent the first Decay (Decay1) from happening until the sample has played through its entire loop one time.
Hold is handy for natural decaying instruments like Piano or Guitar that have small looped samples. When Hold is enabled, the sample will hold its peak volume until it plays through the loop once. The envelope will then start the first decay down to the sustain level. This can help to create for a more realistic ADSR envelope for short, looped samples. It can give them a little more of a natural personality despite the artificial looping.
Decay2: The Decay2 time is either measured in seconds (0-60), or set to Infinite, which overrides the time setting. Decay2 determines how long the Sustain section of the envelope will last before going into the release section of the ADSR envelope, even without letting go of the note. Setting Decay2 to Infinite will cause the sample to sustain indefinitely until you release the note.
Release: Release time is measured in seconds (0-60).This value determines how long it will take for the sample volume to ramp down depending on the Decay2 setting. If Decay2 is set to Infinite, the release will begin when the note is released. If Decay2 is set to an amount of time, the release will begin either after that amount of time passes or if you release the note before the Decay2 time passes.
