RP-12 Owner’s Manual

SECTION 1 - STARTUP

SUPPLYING POWER

Line Conditioning - The RP-12 is sensitive to voltage drops,

spikes,

7

and surges. Interference such as lightning or power “brownouts” can seriously, and in extreme cases, permanently damage the circuitry inside the unit. Here are some ways to avoid this type of damage:

Spike/Surge Suppressors - This is an inexpensive solution to all but the severest of AC line conditions. Surge protected power strips usually cost only slightly more than unprotected strips, making them a worthy investment for protection of all your valuable gear.

AC Line Conditioners - This is the best way to go for total protection from improper line voltages, albeit the more expensive way. Line conditioners constantly monitor for excessively high or low voltages and adjust accordingly, thus delivering consistent power levels.

FRONT PANEL CONTROLS The front panel controls and functions of the RP-12 are as follows (refer to diagram):

1)Pedalboard - The RP-12’s pedalboard consists of twelve switches and a real-time Continuous Controller Pedal. The ten main switches are labeled 1 - 0 (10) and can be set to turn effects on or off, change Programs, or toggle continuous controllers. From the Factory, switches 1-5 are assigned to change programs. Switches 6-0, are used to turn effects on or off. The Bank Up/Bypass (top row, far right switch) move Up through any of ther 25 banks in the RP-12 and will allow you to bypass all the effect functions of the RP-12 by pressing the footswitch down. When the RP-12 is in Bypass mode, the instrument sound is passed directly from the input to the outputs without effects. The Bank Down/Tuner Switch (bottom row, far right) allows you to move down through any of the 25 banks, by pressing, or access the tuner by pressing and holding the footswitch.

Section 1 - Startup

RP-12 Owner’s Manual

2) Display Window - The display window shows all current operating

and programming information and is comprised of several parts: the

LCD display, the input level meter, the Program number indicator,

and DSP Clip indicator LEDs. The LCD display shows all Program names, Parameters and Parameter values, and is the communication interface between you and the RP-12. The input level meter monitors the level of the signal entering the digital section. In the Program number indicator window you will find the currently selected Program number. This changes as you scroll through the available Programs. The functions of the Input Level Meter and DSP Clip indicator LEDs are as follows:

• Input Level Meter - Displays the strength of the signal after the preamp section in 6 dB steps, entering the digital section.

• DSP Clip - Indicates digital information overflow in the processor. When lit, distortion may be heard in the output signal. The guideline for this indicator is: let your ears be the judge. If this indicator lights regularly and no audible distortion is present, it can be ignored. If distortion is audible in the output signal, one or more of the internal analog effects levels or the DSP Master level in the Program must be turned down to eliminate the problem.

3) Program Buttons - The Program <UP> and <DOWN> keys allow you to scroll through the RP-12’s effects Programs. The <STORE> key allows you to store a Program in memory for later recall. The <COMPARE> key allows comparison of an edited Program with the original unedited version before it is stored.

4) Parameter Buttons - The Parameter keys perform several different functions. When the Program Title is displayed, the <UP> and <DOWN> Parameter keys do nothing. The <RIGHT> key will move you to the algorithm section, through the modules of the algorithm and into the parameters of the program. The <LEFT> key moves you in the opposite direction (see the diagram on page 12 for further explanation). Once you have accessed the algorithm screen or parameter screen with the <LEFT> and <RIGHT> parameter keys, the <UP> and <DOWN> keys allow you to increase or decrease the displayed values.

5) Effects Library Buttons - This group of buttons allows you to jump directly to the first Parameter of Modules in the currently selected Algorithm. The buttons in this group are: <COMP>, <DIST>, <EQ>, <REVERB>, <DLY/SMP>, <PITCH>, <MOD>, <MIX>, and <MORE>. Also included in this section and sharing buttons with the <MOD>, <MIX>, and <MORE> buttons are the Function keys (indicated by ¡, ™,and £) which act as menu selection keys in the Utility, MIDI, and Naming menus.

6) Global Buttons - These buttons perform global functions. Some of

Section 1 - Startup

RP-12 Owner’s Manual

these functions include, Utility functions such as LCD contrast,9 Pedalboard , and MIDI setups (including transmit & receive maps). Buttons in this group are: <NAME>, <UTILITY>, and <MIDI>.

7)Main Output Level - This controls the overall output level of the RP-12. It also controls the overall level of the headphones.

8)Continuous Control Pedal - This volume-type pedal allows realtime control over Parameters in the RP-12.

PROGRAM ARCHITECTURE The Program’s Parameter architecture in the RP-12 has been designed to be a linear series of items, rather than a multiple-level menu (see diagram). In other words, instead of including several submenus under a single Parameter heading, all Parameters are included in a single level, and are accessed using the <LEFT> and <RIGHT> Parameter keys. This makes access to specific Parameters of a Program quick and easy, and provides a much clearer picture of exactly where you are in the Program.

Linear Parameter Architecture of a Program

The diagram above shows the linear arrangement of the Parameters in the RP-12. Notice that if you press the <RIGHT> Parameter key from the last item in the list (the Parameter item to the left of the title screen), the display jumps, or “wraps around to” the first item in the Program (in this case, the title screen).

Likewise, if the <LEFT> Parameter key is pressed from the title screen, the display will wrap to the last Parameter in the list. This wraparound menu feature is provided so that Parameters that appear near the end of a long list of items can be just as easily reached as items near the beginning of the menu. If you press and hold either the <LEFT> Parameter key or the <RIGHT> Parameter key, the RP-12 will begin scrolling at high speed through the available Parameters.

ACCESSING FACTORY PROGRAMS

There are three methods for recalling factory Programs.

1)The first method uses the <UP> and <DOWN> Program keys. The procedure is as follows:

From the title screen, press the Program <UP> key. Note that the Program shown in the display changes and the number shown in the LED display increments by one each time the Program <UP> key is pressed. Pressing the Program <DOWN> key causes the opposite to occur: the RP-12 decrements through the Programs in memory.

Section 2 - Basic Operations

RP-12 Owner’s Manual

• To scroll at high speed through the Programs in13memory, press and hold either the <UP> or <DOWN> Program key.

2) The second method uses the RP-12’s pedalboard. When you change programs using the pedalboard, any unstored modifications you have made to a Program will be lost.

3) The third method is through the use of MIDI. This method will be covered later in the MIDI section of this manual, pg. 58.

TUNING WITH THE RP-12 To access the Tuner using the RP-12 pedalboard, do the following:

Press and hold the Bank Down/Tuner switch (in the lower right corner of the pedalboard). The display reads:

TUNER A=44O

---- -- --

Begin tuning your instrument. As you tune, the note name is shown on the top line of the display, while vertical bars appear on the second line of the display and begin strobing. If the note is sharp, the bars will strobe from left to right. If the note is flat, they’ll strobe from right to left. When the note is in tune, the strobing bars will stop moving and asterisks will appear around the note name on the top line of the display.

After a few seconds of tuner inactivity, the display returns to:

TUNER A=44O

---- -- --

Exit Tuning Mode by pressing any pedal or button.

Section 2 - Basic Operations

RP-12 Owner’s Manual

14CHANGING THE TUNING REF You can easily change the RP-12’s tuning reference by using the <UP/DOWN> Parameter buttons while in tuner mode. The top line of the display will show the current setting. The default factory setting is: A=440 Hz. The tuning reference control ranges from 427 Hz to 453 Hz, which is the equivalent of ±50 cents (1/2 semitone) in either direction from 440 Hz.

Scrolling down below# 427 Hz, you can# access the alternative tuning references of: A= G , A=G, and A=F .

When you use any of the alternate tuning as your reference, tune your instrument so that the display shows normal tuning (E, A, D, G, B, & E for guitars) and the RP-12 will do the rest ( the display shows normal tuning, but you’ll actually be tuning to the selected reference).

TUNER A=G

---- -- --

Exit Tuning Mode by pressing any pedal or button.

ASSIGNING PROGRAMS TO FOOTSWITCHES

The RP-12 has a special function within it’s operating system, that allows you a quick and painless method of assigning any one of the 256 programs in the unit, to any one of the bottom row of footswitches (1-5). For example, you would like to store program 53 (Blue Naked), to footswitch 1. The procedure is as follows:

From program 53, press and hold the <Utility> function button. The LEDs in the bottom row of footswitches will scroll along the botton row of footswitches, and the display will appear like this:

Select Desired

Foot Switch

Select and press the desired footswitch, and assignment is made. Now, whenever you press that footswitch, program 53 will be recalled.

For a more in depth explanation on program assignment, please refer to page 49 for more information.

ASSIGNING PARAMETERS TO FOOTSWITCHES

You can easily assign any effect parameter to a Continous Controller by performing a simple linking procedure using the front panel controls of the RP-12. For example, If you wanted to assign Footswitch 7 (CC 22) to control the Compressor On/Bypass Parameter in Program 5 (Wham & Eggs). The procedure is as follows:

• From the Program title screen, scroll to the Compressor

Section 2 - Basic Operations

RP-12 Owner’s Manual

On/Bypass parameter, by either pressing the Parameter15<right > button five times, or pressing the <COMP> Effects Library Button. Now press and hold the <MIDI> button, and the display reads:

¡Link 5 =NoLink ™Assign

Press function button <Mix ™> to assign a CC, and the display will appear like this:

Comp On/Bypass

 

No Link

³

To assign CC to the parameter, press Footswitch 7, and the display will appear like this:

Comp On/Bypass

Link to:CC 22 ³

At this point, the Link has been made. Press the function button <MIDI> to exit, and then press store to save the link assignment.

For a more in depth explanation of Assignment of CCs to parameters, please see pg. 50 for more information.

Section 2 - Basic Operations

RP-12 Owner’s Manual

16SECTION 3 - PROGRAMMING

USING THE FUNCTION BUTTONS The RP-12 has three Function keys. They are located in the bottom row of the Effects Access buttons and they share buttons with the <MOD>, <MIX>, and <MORE> options. Each Function key is numbered and performs several functions in the Utility and MIDI modes (depending on the selected menu screen). These buttons are also used in the Program naming process (see Storing/Naming on page 19). See pg. 49 for more on the Utility Button. See pg. 58 for more on the MIDI Button.

¡™& £ are used in the display to indicate which function key to use.

MORE SPECIAL CHARACTERS There are several special characters that the RP-12 uses to tell you at a glance exactly what it is doing. Some special characters in the RP-12 are in inverted type, that is, reversed out of a black background, and they will usually appear in the upper right-hand corner of the Program Title screen.

ßIndicates that the Cabinet Emulator is currently active.

Ç Indicates that a MIDI continuous controller is linked to the Parameter.

åºCharacters from this group are used for distinguishing between Modules of the same name in a single Algorithm. This is an instance in which a special character will immediately follow the Module name, rather than appear in the corner of the display.

*Indicates a Program has been modified.

( ) Indicates the value within the brackets is a stored or saved value.

Section 3 - Programming

RP-12 Owner’s Manual

THE EFFECTS LIBRARY BUTTONS 17

The Effects Library buttons are used to jump to specific places in a Program. For example, if a Program contains two choruses and you want to change the delay time on only one of them, you could press the <MOD> Effects Library button from Program Title screen and you would jump to the first Parameter of the first chorus in the Algorithm. Press the button again, and you are taken to the first Parameter of the next chorus in the Algorithm.

ABOUT THE I /O MODULE Each Program in the RP-12 is equipped with Compression, Distortion, Clean / Distortion Level, Noise Gate, DSP Master Level, Parametric EQ, Wet/Dry Mix, and Cabinet Emulator controls. These items are permanent residents of every Algorithm in the unit.

This group of items is called the Input / Output Module (or I/O Module) because they are always a part of both the input and output audio paths of the RP-12. The following diagram shows how the I/O Module affects the signal as it flows through the unit.

MODIFYING FACTORY PROGRAMS

After you’ve had time to familiarize yourself with the RP-12, you may find that there are several factory Programs that are very close to what you’re looking for, but need a few small tweaks to get them perfect. Program 2 (Clean and Tight) has a chorus and delay. Let’s assume that in order to work in your application, it needs to have a 60Hz cho-

Section 3 - Programming

18

 

 

RP-12 Owner’s Manual

rus speed. Using this Program as an example for Program modifica-

 

 

tion, the procedure for changing the Chorus Speed is as follows:

 

 

• From the Program title screen, scroll to Program 2 using the

 

 

<UP/DOWN> Program buttons. The display reads:

 

 

 

 

 

Clean and Tight

 

 

 

DCho³2TDly³2Pans

 

 

 

 

 

 

 

• Using the <RIGHT> and <LEFT> Parameter buttons, scroll to the

 

 

CHORUS SPEED Parameter.

 

The display reads:

 

 

 

 

 

Chorus Speed

 

 

 

(0.28Hz)

 

 

 

 

 

 

 

NOTE: By pressing the <MOD> key you can skip directly to the

 

 

first Parameter of the Chorus effect within the Algorithm, then con-

 

 

tinue scrolling with the <RIGHT> Parameter key to the Chorus

 

 

Speed parameter.

 

 

• Using the <UP> Parameter key, scroll upward until you reach

 

 

0.60Hz. The display reads:

 

 

 

 

 

 

Chorus Speed

 

 

 

0.60Hz

 

 

 

 

 

 

If you change Programs at this point (either through MIDI, the pedal-

 

board, or the Program buttons), any modifications that you have made

 

to the Program will be lost. In order for the RP-12 to remember the

 

changes that you have made, you must store the Program in memory.

 

The procedure for storing Programs is covered in more detail on pg 20.

BASIC PROGRAM CREATION

There are three requirements for creating a Program on the RP-12.

 

The first is that an Algorithm needs to be assigned to the Program;

 

second, Parameters must be modified to your liking, and third, the

 

Program must be stored in memory in order to be recalled for later

 

use.

SELECTING AN ALGORITHM

The Algorithm you choose for a Program determines the basic function

 

of the Program. It is therefore necessary to choose an Algorithm that

 

contains all the Modules you want to use in an appropriate configura-

 

tion (for a complete listing of the RP-12’s algorithms, see page 67).

 

The Algorithm selection screen for all Programs in the RP-12 is one

 

screen to the right of the title screen.

 

NOTE: It may be easiest to select a Program that uses the Algorithm

Section 3 - Programming

you want and begin editing Parameters from there.

RP-12 Owner’s Manual 19

The Algorithm selection screen works in conjunction with the LED display to show the currently selected Algorithm number. When in the Algorithm selection screen, the LCD display looks something like this:

ALGORITHM NAME--> Wham³2TDly³Revrb

Comp Dist MVol³ <-- EFFECTS ROUTING WITHIN ALGORITHM

To select an Algorithm for a Program, the procedure is as follows:

• From the title screen, press the <RIGHT> Parameter key once. This is the Algorithm selection screen. The name of the currently selected Algorithm is shown on the top line of the display, while the bottom line shows the effects in the Algorithm.

NOTE: When there are more effects in the Algorithm than will fit on a single line of the display, an arrow will appear in the first and/or last character of the bottom line of the display. These arrows indicate that there is more information about the effects that could not be displayed on a single screen. To see the remaining information, simply press the <RIGHT> or <LEFT> Parameter key (depending on the arrow direction indicated in the display).

• Use the <UP> and <DOWN> Parameter buttons to select the Algorithm you want to use with the Program. The LED display now shows the Algorithm number as you scroll up or down.

• Use the<RIGHT> and <LEFT> Parameter buttons to begin modifying the Parameters of the currently selected Algorithm to suit your purpose.

NOTE: When you change the currently selected Algorithm, the default Parameters selected for the new Algorithm are taken from the first Factory Program in memory that uses that Algorithm.

 

Once you have selected the Algorithm you want to use and modified

 

its Parameters, an asterisk appears in the upper right corner of the title

 

screen. This asterisk indicates that the Program has been modified

 

and any changes you have made will be lost if not stored in the RP-

 

12’s memory.

NAMING PROGRAMS

In order for modified Programs to be available for later recall, you must

 

store them in memory. This is accomplished using the <STORE> key.

 

The RP-12 also allows you to give your Programs custom names up to

 

15 characters in length. This is accomplished using the <NAME> key.

 

The naming procedure uses the <UP> and <DOWN> Parameter but-

 

tons, and the Function buttons ¡ ™ & £ to change the letters of the

 

alphabet. The <MOD ¡> key changes the character from either upper

 

or lower case, and jumps you to the letters of the character set. The

Section 3 - Programming

20

 

 

RP-12 Owner’s Manual

<MIX ™> key puts a space into the Program name, and jumps you to

the special characters in the character set. The <MORE £> key inserts

an ‘0’, and jumps you to the numbers section of the character set. The

complete procedure for naming and storing a Program is as follows:

 

 

• After you have made all the necessary modifications to the

 

 

Algorithm, press the <NAME> button once. The RP-12 is now in

 

 

Name mode. The display shows:

 

 

 

 

 

 

[PROGRAM NAME]

 

 

 

¡CAPS ™SPC £NUM

 

 

 

 

 

 

The blocked numbers preceding each option on the bottom line indi-

 

cate the Function key that will perform the function shown.

 

 

• Using the <UP/DOWN> Parameter buttons, scroll to the charac-

 

 

ter you want to use, or press one of the Function buttons. When

 

 

you have selected the character you want, press the <RIGHT>

 

 

Parameter key. Note that the cursor moves to the next character.

 

 

Repeat this procedure until the Program name is satisfactory.

 

Unique to the RP-12 naming process, are several special naming func-

 

tions. The <COMPARE> and <STORE> buttons allow you to bump an

 

entire name or section of a name either left or right in one-space incre-

 

ments. The procedure is as follows:

 

 

• In Name mode, use the <RIGHT> and <LEFT> Parameter but-

 

 

tons to place the cursor underneath the character to be moved.

 

 

• Press the <COMPARE> or <STORE> buttons to move the char-

 

 

acters either left or right.

 

The Program <UP> key copies the character the cursor is under into

 

memory. This allows you to place a copy of that character (using the

 

Program <DOWN> key) anywhere else in the name that you want.

 

The procedure is as follows:

 

 

• In Name mode, use the <RIGHT/LEFT> Parameter buttons to

 

 

place the cursor under the character to be copied.

 

 

• Press the Program <UP> key. The selected character is copied

 

 

into memory.

 

 

• Move the cursor to the location into which you want to place a

 

 

copy of the character and press the Program <DOWN> key. The

 

 

copy appears in the location you selected.

 

 

NOTE: Press the <UTILITY> button to abort the operation. When

 

 

you change programs the original name will return.

Section 3 - Programming

RP-12 Owner’s Manual

• When the Program name appears as you want it, press the

 

 

<NAME> button to exit the name selection mode.

STORING PROGRAMS

Once you have dialed in the program how you want

given it a

21it and

 

name, press the <STORE> button. The display reads:

 

 

 

 

 

 

 

Store To Prg ##

 

 

 

 

[PROGRAM NAME]

 

 

 

 

 

 

 

This screen allows you to select the Program location in which you

 

want to store the new Program.

 

Using the <UP> and <DOWN> Program buttons, scroll to the Program number location in which you want to store the new Program.

To store the Program in the selected location, press the <STORE> key again. The display briefly reads:

***Storing***

after which you will automatically be returned to the previous mode. To abort the command, press <COMPARE>.

The Store function can also be used to copy Programs from one memory location to another. If no changes have been made to the selected Program and the <STORE> button is pressed, the display reads:

Copy To Prg ## [PROGRAM NAME]

Select the memory location in which you want to place a copy of the selected Program using the <UP> and <DOWN> Program buttons, and press <STORE> again. The display briefly reads:

***Copying***

after which you will automatically be returned to the previous mode. To abort the command and return to the Program, press the <COMPARE> button.

SECTION 4 - EFFECTS AND PARAMETERS

BOUT THE EFFECTS LIBRARY The Effects Library consists of all the effects Modules you can find in

the RP-12. Broken down into individual categories, specific Modules

 

 

 

and their abbreviated library names are as follows:

Comp

Analog compressor tailored for instruments

 

 

 

 

 

 

 

 

Distortion

 

Dist

Analog distortion (3 solid-state types)

 

 

 

 

 

 

 

 

 

 

The analog section of the RP-12 includes the compressor and the dis-

 

 

 

tortion section. These two items are always available in all Programs.

 

 

 

The analog effects and their Parameters are as follows:

COMPRESSOR

The RP-12’s compressor is a high-quality, low-noise circuit specially

 

 

 

designed for guitars. Compression can be used to increase sustain

 

 

 

and to tighten up guitars, and is particularly useful on clean sounds.

 

 

 

Parameters of the RP-12 compressor are as follows:

 

 

 

Comp On / Bypass........Turns the Module on or off. When Modules are

 

 

 

 

 

bypassed their Parameters disappear from the

 

 

 

 

 

Parameter menu. To see the Parameters, you

 

 

 

 

 

must turn the Module on.

 

 

 

Comp Amount ...............Controls the amount of compression applied to

 

 

 

 

 

the signal. Higher settings yield a tighter, more

 

 

 

 

 

focused sound, while lower settings allow bet-

 

 

 

 

 

ter dynamics. Ranges from 0 to 31.

 

 

 

Comp Level ...................Sets the output level of the compressor before

 

 

 

 

 

feeding to the distortion. Higher settings send

 

 

 

 

 

more signal level into the distortion, yielding

 

 

 

 

 

extra gain and drive. Varies from 1 to 7.

DISTORTION

The distortion section of the RP-12 is capable of producing three dis-

 

 

 

tinctly different types of distortion. These three solid-state distortion

 

 

 

sounds range from lightly overdriven, to screaming grunge. The

 

 

 

Grunge setting gives you extremely high-gain distortion, free from the

 

 

 

mush and tonal sacrifices typical of other manufacturers’ products.

 

 

 

Dist On / Bypass ...........

Turns the Module on or off. When Modules are

 

 

 

 

 

turned off, their Parameters disappear from the

 

 

 

 

 

Parameter menu. To see the Parameters, you

 

 

 

 

 

must turn the Module on.

 

 

 

Distortion Type ..............

Selects the type of distortion to be used in the

Section 4 - Effects and Parameters

RP-12 Owner’s Manual

Program. Options are: OVERDRIVE23- Solidstate overdrive with extra punch. HEAVY SUSTAIN - Smooth, warm distortion sound with lots of sustain. GRUNGEHigh gain distortion which is tight and highly focused for powerful rhythms and leads.

Distortion Gain ..............Controls the amount of distortion produced by the RP-12. High settings produce greater gain and drive for effortless soloing, while low settings offer better nuance and touch control.

Ranges from 0 to 11.0.

Dist/Clean Level ............This Parameter allows two separate levels to be set. If the Distortion is turned on, the Distortion level can be adjusted. If the Distortion is turned off, the Clean level can be adjusted. Both level settings are saved when the Program is stored. Settings include MUTE or ranging from -60dB to +12dB.

The equalizer Modules provided in the RP-12 offer superb noise performance, and allow accurate tonal shaping of many different types of sound sources. A 4-band parametric equalizer with adjustable Q is available in all Algorithms. The RP-12 also features a 10-band Graphic Equalizer module. All equalizer Modules offer silent, accurate (doubleprecision) tonal shaping.

Adjustable Q equalizers offer the ability to control the bandwidth of the boost/cut ranges. High Q settings yield extremely narrow bandwidth, where boost and cut have minimal effect on adjacent frequencies of the program material. Low Q settings affect a wider number of frequencies when the selected band is boosted or cut.

With a Q setting of 2, you can see that a large number of frequencies are affected by boosting the center frequency. Now take a look at the middle and lower curves in the diagram, and notice the much narrower bandwidth of the curves with a Q setting of 4 and 8.

The RP-12’s programmable Cabinet Emulator circuitry allows you to use it in both recording and live situations, without lugging heavy amps and/or cabinets around. Just connect the RP-12 outputs to a mixing console, and kick in the Cabinet Emulator. No miking hassles, no heavy equipment, just full on mic’d cabinet sound. Programs can be stored with different Cabinet Emulator settings so you can customize your banks or set lists for whatever sound types you need. The Cabinet Emulator can be controlled globally from the <UTILITY> Menu. Parameters are as follows:

Cabinet On / Bypass .....Turns the Module on or off. When Modules are turned off, their Parameters disappear from the Parameter menu. To see the Parameters, you must turn the Module on.

Cabinet Type.................Selects the tonal characteristics of the simulated cabinet. There are 10 different cabinet types; 3 warm cabinets, 3 medium cabinets, 3 bright cabinets, and 1 full bandwidth cabinet for maximum frequency response. The full bandwidth cabinet is useful when the global Cabinet Emulator is active (in the Utility menu), and a full bandwidth sound is still desired.
