The matrix provides information regarding the current preset and parameter edit functions. In

Performance mode, the LEDs running down the left side of the Matrix provide a visual indication of which effects are in use for the currently selected preset. While editing a preset, the LEDs indicate the Effect row currently selected for editing. In Tuner mode, the LEDs indicate whether the note played is sharp, flat, or in tune.

The Display provides information for different functions depending on the mode that has been selected. In Performance mode, the Display will show the currently selected preset name and number. In Edit mode, the Display will show the name and value of the parameter being adjusted.

In Tuner mode, the Display will show the note played.

6. Drums

The Drums button is used to turn on and off the RP255’s built-in drum machine. When the

Drums button is turned on, the Drums LED lights and the selected drum pattern plays continuously. Select the Drums row using the Edit buttons and use Knobs 1-4 to change the style, pattern, tempo, and level of the drum machine. See page 39 for more information about the drum machine and a list of patterns.

The Expression Pedal provides real-time control of the RP255’s Volume, Wah, or the assigned effect parameter. Almost every parameter is available for Expression Pedal control. The

Expression Pedal is equipped with a V-switch that activates or deactivates the Wah feature when you apply extra pressure to the toe.
