Selecting a Program
When creating or editing a sound, you must first start by choosing a Program. The Program number does not necessarily need to be the
location which you intend to have the sound reside, as you can save your creation to any user Program number during the store process.
You do have to start with one of the user or factory Programs. It is not possible to start with a completely empty Program. Pick a Program
which will be your starting point.
Creating Programs
The RP21D lets you create your own Programs, or fine tune the original settings to suit your needs. Editing and creating is a very simple
process that doesn’t require a lot of time dedicated to learning the menus. Once a Program has been edited to your liking, you may store
those settings to any of the 128 user Programs. Remember that the user Programs are duplicates of the factory Programs so, you are not at
risk of losing any of the sounds that the RP21D came with.
Preamp Defaults
Once you have selected the Program, press the Preamp button once. All of the modules in the Preamp section will begin flashing in the
display. This is the default page of the Preamp. A default is a way of quickly getting several effects and/or parameters set up without having to
Program each one individually. It remembers the settings of all of the preamp effect modules and will set all parameters to the values stored
in the default. There are 30 factory and 30 user preamp defaults in the RP21D. You can choose one of the factory preamp defaults that suits
your needs, or tailor your basic sound to get a custom preamp tone that you will want to use for several other Programs. You can then store
your custom default to a user default location. Then when you create a new Program in which you wish to use that same preamp tone, all
you have to do is select the same default setting. This saves you the time and hassle of reprograming the preamp every time you create a
Program.
Editing the Preamp
Let’s suppose that you are not going to use a default for the preamp, or that you are going to create a custom default setting. This means that
you will need to edit all the effects in the preamp individually. To access the effects within the preamp, press the preamp button twice. The
Compressor box will begin to flash indicating that you are about to edit the compressor module. Successive presses of the preamp button
will advance through all of the effect modules in the preamp section. Once you reach the end of the preamp modules, the RP21D will “loop
around” and start at the beginning again. Every module will have parameters associated with that effect available for editing. These
parameters will be shown in the 1-4 positions of the display. To adjust any of these parameters, press any of the 1-4 buttons and an arrow
will appear next to the corresponding parameter. Rotate the Data Wheel to change the value of that parameter.
When the preamp has been edited to suit your requirements, you may store the settings to a user default for use in other Programs, or move
on to editing your digital effects within the current Program.
The Preamp Effects
The preamp contains a total of 7 different effects. The effects were laid out in the most logical and best sounding order and cannot be
changed. The guitar signal can go through any or all of the modules. The first effect that your guitar goes through is the compressor. The
output of the compressor is then fed to the Wah. After the Wah effect, the signal can be split and run through two discrete Distortion paths.
Each Distortion path has a dedicated Equalizer. The expression pedal can be assigned to morph between the two Distortion paths (see page
50 for more information on morphing). The outputs of the Equalizers are sent into a Noise Gate which is the end of the Preamp effect
modules. Each effect in the preamp (except for the Wah) includes a default menu exclusive to that effect.
