EXS24 mkII envelope overview
EXS24 mkII features two envelope generators per voice, abbreviated as ENV 1 and ENV 2 in
the interface and router. For details on the roots of the term envelope generator and its basic
function, see Amplifier envelope overview on page 486.
The parameters of ENV 1 and ENV 2 are identical.
••
ENV 1 controls the filter over time.
••
ENV 2 defines the changes in level over time—for each note played.
Both envelopes, however, are also available for simultaneous use as sources in the router.
The envelope time parameters (Attack, Decay, and Release) are also available as modulation
destinations in the router.
Envelope 1 parameters
Envelope 2 parameters
Envelope parameters
••
A(ttack) slider: Defines the time it takes for the level of a note to rise from an amplitude of 0 to
the set amplitude. The Attack time sliders of both envelopes are divided into two halves.
••
The lower slider half defines the attack time when the keys are struck hard, at maximum
velocity. The upper slider half defines the attack time at minimum velocity. Drag the area
between the two slider halves to move them both simultaneously. If this area is too small to
drag, drag above or below the slider in the control area.
••
D(ecay) slider: Defines the time it takes for the level of a held note to fall to the sustain level
after the attack phase has completed.
••
If the Sustain level parameter is set to its maximum value, the Decay parameter has no effect.
••
If the Sustain level is set to its minimum value, the Decay parameter defines the duration or
fade-out time of the note.
••
S(ustain) slider: Determines the sustain level.
••
R(elease) slider: Defines the time required for the (sustain) level to decay to 0—after the key
is released.
••
Time via Key slider: Applies to both envelopes. Scales (lengthens or shortens) the envelope time
intervals. Note that position C3 is the center point.
••
Time intervals for zones assigned to keys above C3 can be made shorter with the left slider.
Time intervals for zones assigned to keys below C3 can be made longer.
••
Curve slider: The attack curve slider applies to both envelopes, determining the shape of the
envelope attack curve.
