Reverb
Controls the reverb depth of the track. Click and hold the mouse and a pop up fader will open allowing you to set the reverb to whatever value you like. Double click or press Enter to type in a reverb value.
Tip: Use the + and - keys on the numeric keypad to increment and decrement by a value of 1 or press the [ and ] keys to increment and decrement by a value of 10.
Note that changing the reverb of a track also changes the reverb for all tracks that are set to the same MIDI channel. This is because there is only one MIDI reverb controller for each MIDI channel.
