DigiTech RP21D - Manual (Page 13)

The Programs
Programs are named and numbered locations of sounds that have been programmed into the RP21D. Programs can be recalled with the
footswitches or the Data Wheel. The RP21D comes with 128 factory and 128 user Programs available. The factory Programs will not allow
you to store any changes to them. The user Programs are locations where your creations may be stored. You will notice that the 128 user
Programs are exact duplicates of the 128 factory Programs. This allows you to make your own Programs without worrying about losing any
of the sounds that the RP21D came with.
When you select a Program, the name and number of the Program will be shown in the display. An icon directly beneath the number of the
Program will indicate whether the Program is a factory Program or a user Program. Depending on whether or not you have changed any
footswitch assignments, the top row of footswitches may have one or more LEDs lit, indicating the status of the effects assigned to those
switches.
The RP21D includes a variety of different Programs. Go ahead and audition several of the Programs. Once you have found some sounds that
are close to what you are looking for, you can edit those Programs until they are exactly what you want.
The Footswitches
The RP21D includes 12 footswitches which can be assigned to perform different functions. The footswitches can call up Programs, turn
effects on or off within a Program, change banks, bypass the Program, or access the tuner. Other functions can also be performed with the
footswitches such as setting up a delay time by tapping your foot on a switch in time with the tempo of a song. You can also use the
footswitches to change a parameter to a specific value.
From the factory, the footswitches have been set up to call up Programs with the bottom row (switches 1-5), and turn effects on and off with
the top row (switches 6-0). You may change assignments to any of these ten switches to suit your needs. For more on assigning the
switches, see page 48. The top and bottom switches on the far right (next to the expression pedal) cannot be reassigned. These switches are
permanently assigned to advance banks with the top switch, or decrement banks with the bottom switch. The top right switch will also
bypass the current Program by pressing and holding the switch. The bottom right switch will access the tuner by pressing and holding the
switch.
The Expression Pedal
As you go through the different Programs that came in the RP21D, you will find that the expression pedal has different functions. This pedal
can be assigned to control any parameter of any effect in the RP21D. Rocking the pedal back and forth will change the value of the
parameter that the pedal has been assigned to control. You may assign minimum and maximum values (stop points) for each parameter that
you control with the pedal. For more on assigning the expression pedal, see page 49.
The Effects
Creating your own signature sound with the RP21D is easy and intuitive. The RP21D is divided into two sections of effect modules: the analog
or preamp modules, and the digital effect modules. Each section may be accessed individually for the purpose of modifying the available
effect modules.
