Anatomy of an Envelope

An envelope creates a variable control signal. It can be used, for instance, to modulate the filter settings

of a sound over a given period of time.

For Drum Programs, the software offers two envelope types comprised of separately controllable

parameters. Click the AD box to check or uncheck it, letting you switch between two envelope types: AD

(checked) or AHDS (unchecked).

For Keygroup Programs, the software offers only AHDS envelopes.

With AHDS envelopes, the following happens when you trigger a

sample:

1. Within the period of time you have defined with the Attack (Atk)

parameter, the sample volume rises to its maximum value.

2. The sample's maximum volume will be maintained during the

Hold phase.

3. During the Decay phase, the sample's volume will gradually drop to the sustain level.

4. The sample's volume will stay at the sustain level (Sust) until the pad or key is released.

With AD envelopes, the following happens when you trigger a sample:

1. Within the period of time you have defined with the Attack (Atk)

parameter, the sample volume rises to its maximum value.

2. The sample's maximum volume will be maintained until its Decay

phase, when the sample's volume will gradually drop to zero over

the set duration. Click the Type drop-down menu to select Decay

From Start (the volume will start decreasing immediately after reaching its maximum level) or Decay

From End (the maximum volume will be maintained for a hold phase until it reaches the decay

phase).
