Reverb Effects

The P-150's internal DSP digital signal processor generates three types of realistic
reverb effects, or simulated ambient environments, which you can apply to the
voices.
These include ROOM, which simulates the natural reverberations of sound in a
normal-sized room, STAGE, which simulates the natural reverberations of sound
in a night club, and HALL, which simulates the natural reverberations of sound in a
relatively large concert hall.
As you select each voice you will notice that a specific reverb effect is already
assigned to it, indicated by a lit LED to the left of the name of the selected reverb
type. These are the initial default assignments set at the factory, but you can select
any reverb effect you wish for each voice, or even turn the reverb effect off. You
can also change reverb depth on the spot.

SELECTING A REVERB TYPE

Press the [REVERB] button once or more.
When you press the [REVERB] button repeatedly, the reverb types will be selected
in order as follows: ROOM, STAGE, HALL, then OFF.
Note that each time you select a reverb type, a message will briefly display in the
LCD screen, as follows.
REVERB DEPTH
This temporary message displays the current depth level for the reverb type that
you just selected, between 0 and 7.
You can easily change the depth level for the currently selected reverb type.
