By using the SL-2001 instead, the noise and reliability problems of a mechanical volume pedal are eliminated. The diagram
below illustrates the volume control function in a preset using three zones.
Three zones are active in this example. The initial volumes have been programmed on the VOLUME screen to achieve the
desired relative mix. If the source controller (usually a foot pedal connected to cv 1 or 2) is at the top of its range, the three
sound modules will remain at the initial volume levels. As the pedal is moved downward, volume messages are issued to
each of the three sound modules. The relative mix between the sounds is retained, until eventually all volume levels reach
zero. Variations among different sound modules and manufacturers can cause slight volume mistracking as the controller is
moved; initial volumes may have to be adjusted for the best response over the range of interest.
The volume control function is not available if the zone is bypassed, and the parameter values are not displayed.
KEY HOLD
The KEY HOLD function is used to produce the same effect as the Sostenuto pedal on a grand piano.
