Key
This knob defines the amount of filter cutoff frequency as determined by note number.
When Key is fully turned to the left, the cutoff frequency is not affected by the note
number, and is identical for all notes played. When Key is set fully right, the cutoff
frequency follows the note number 1:1—if you play one octave higher, Cutoff is also
shifted by one octave. This parameter is very useful in avoiding overly filtered high notes.
Filter Envelope
In the lower section of the EXS24 mkII interface, ENV1 is the ADSR envelope generator
for the filter. This envelope allows you to control the filter over time. It offers Attack,
Decay, Sustain, and Release parameters.
Drag the A, D, S, and R sliders to configure the appropriate parameter. The attack time
can be reduced by velocity: the upper half of the slider determines the time for
minimum velocity, the lower half for maximum velocity. By clicking and dragging in-
between the two slider segments, both can be moved simultaneously.
Time Curve
The sliders apply to both the filter (ENV1) and volume (ENV2) envelopes; the left slider,
known as time via key, can be used to scale (lengthen or shorten) the time intervals of
both envelopes. Note position C3 is the center point; time intervals for all zones
assigned to keys above C3 can be reduced in length with this slider. All time intervals
for zones assigned to keys below C3 can be lengthened. The (Attack) Curve slider
determines the shape of the envelope attack time.
Volume and Pan Parameters
The following section describes the Volume and Pan parameters of the EXS24 mkII.
Level via Vel
This slider controls the volume of the sound. The Level parameter can be modulated by
velocity: the upper half of the slider determines the volume for maximum velocity, the
lower half for minimum velocity. By clicking and dragging in the area between the two
slider segments, you can move both simultaneously.
