Volume and Pan Parameters
Level via Vel
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.
Volume
The main volume parameter for the EXSP24. Move this knob to find the right balance
between avoiding distortion and getting the best (highest) resolution in the channel
fader and the Level via Vel slider.
Key Scale
This parameter modulates the sound’s level by note number (position on the
keyboard). Negative values increase the level of lower notes. Positive values increase
the level of higher notes.
Amp Envelope (ENV 2)
This is an ADSR envelope generator for controlling the sound’s level over time. It offers
Attack, Decay, Sustain, and Release parameters.
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.
