An envelope, in its simplest terms, is a representation of a sound’s dynamic properties as they change over time. All acoustic sounds have their associated envelopes. The three primary aspects of any given sound that can be quantified in terms that can be manipulated by way of an envelope are amplitude (volume), frequency (pitch), and harmonic content (timbre or filter).

The following explanations of the Envelope Parameters apply to both the Amplitude and the Filter Envelope settings with one exception: the Filter Envelope does not have a Hold setting.

Pre-attack level (%)

The Pre-attack level is adjusted as a percentage of full amplitude (0 to 100). It is the very first point on the ADSR envelope and sets the initial volume level of the attack.

For example, a Pre-attack 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 time (sec)

The attack time is measured in seconds (0.000-10.000).

This parameter sets the amount of time that it takes for the attack to reach its full volume. For most instruments, this time will range from zero to at most a half second for a natural sounding instrument. However extreme settings can be used for special effects to put a slow volume ramp up for each triggered note.

Decay 1 Time (sec)

The Decay 1 Time is measured in seconds (0.000-60.000).

This parameter sets the amount of time for the first decay of the envelope. It decays from the peak level of the attack down to the sustain level.

Hold

If a sample has a loop point, the Hold function will prevent the first decay (Decay 1) from happening until the sample has played through its entire loop one time.

This is handy for natural decaying instruments like Piano or Guitar that have small looped samples. When Hold is set to “Yes” the sample will hold its volume until it plays through the loop. Once it has played through the loop, it will then start the first decay down to the sustain level. This can make for a more realistic envelope for short looped samples. It gives them a little more of a natural personality despite the artificial looping.

Note: Hold is available on the Amplitude Envelope but not the Filter Envelope.

Sustain level (%)

The Sustain level is adjusted as a percentage of full amplitude (0 to 100).

After the first decay dies down, the sample audio will sustain for a period of time depending on the Decay 2 settings. This setting determines the volume level of this sustaining portion.
