Gate
In the MPX 100, the Gate program pro-
vides a fairly constant sound with no decay
until the reverb is cut off abruptly. This pro-
gram works well on percussion — particu-
larly on snare and toms, but be sure to
experiment with other sound sources as well.
* Note that audio is muted briefly when Duration is
altered with Adjust.
Gated reverbs were originally created by feeding a reverb, such as a metal plate,
through an analog gate device. The decay time was set to instant, and the hold time
varied the duration of the sound.
