The RPx400 does not have a power switch. To turn the RPx400 off, disconnect the included PS0913B power supply from the power jack to an AC outlet.

Mono Amp Rig

Connect your guitar to the Input of the RPx400. Connect a single mono instrument cable from the Left 1/4 Line Output of the RPx400 to the instrument input or effect return on your amplifier. This connection scheme also applies for use with a power amp/speaker cabinet rig.

Effect Definitions

Each effect within the RPx400 can be programmed to suit your personal taste and application. Understanding how these effects alter the sound, and how each parameter alters the effect helps you achieve the sound you are looking for. The following overview of the RPx400s effects outlines what each effect and parameter does.

Pickup/Wah

The Pickup Simulator provides the thick tone of a humbucker pickup to a guitar with single coil pickups, or the bright edgy sound of a single coil pickup to a guitar with a humbucker. This lets you have the best of both worlds without having to change guitars during a performance. Wah is an effect controlled by the Expression Pedal. As the Expression Pedal is rocked back and forth, it makes the guitar sound as if it is saying Wah. The Wah is engaged and disengaged by applying pressure to the V-Switch located under the toe of the Expression Pedal. See Page 21 for more information regarding the V-Switch. Pickup Off/Type - The Number 1 Knob selects the type of Pick Up to be be simulated. Values include: SC>HUM (Gives a single coil pick up the warm tone of a humbucker), and HUM>SC (Gives a humbucker the unique sound of a single coil), or turns Pickup Simulation off. Wah On/Off- The Number 2 Knob turns the Wah effect on or off. Wah Type - The Number 3 Knob selects the type of Wah. Values include: CRY (Cry Wah is a traditional sounding Wah), BOUTIQ (Boutique Wah is a wide sweeping Wah with a more modern sound) and FULRNG (Full Range Wah sweeps the entire spectrum of audible frequencies). Wah Minimum - The Number 4 Knob is used to select the minimum point the Wah reaches in the toe up position of the Expression Pedal. Ranges from 1 to 99. Wah Maximum - The Number 5 Knob is used to select the maximum point the Wah reaches in the toe down position of the Expression Pedal. Ranges from 1 to 99.

Compressor

A Compressor is used to increase sustain, tighten up the guitar signal, and prevent the signal from clip-
ping the input of other effects. It sets a maximum boundary (Threshold) for the strength of a signal. If a signal exceeds the Threshold, it is adjusted based upon the compression ratio setting. Comp On/Off - The Number 1 Knob turns the Compressor on (On) and off (OF). Attack - The Number 2 Knob adjusts the length of time it takes for the Compressor to respond to a signal exceeding the Threshold. Values include: fast, medium, and slow. Ratio - The Number 3 Knob adjusts the input to output ratio once the Threshold has been exceeded. For instance, a Ratio of 4 to1 means that a signal exceeding the Threshold by 4 dB will only be allowed 1 dB of increased output. Ranges include: 1.2-1 (1.2 to 1), 1.5-1 (1.5 to 1), 1.8-1 (1.8 to 1), 2.0-1 (2 to 1), 2.5-1 (2.5 to 1), 3.0-1 (3 to 1), 4.0-1 (4 to1), 5.0-1 (5 to 1), 8.0-1 (8 to 1), 10-1 (10 to 1), 20-1 (20 to 1), and 00-1 (infinity to 1). Threshold - The Number 4 Knob adjusts the maximum strength the signal is allowed to reach before the compressor begins to work. Ranges from 1 to 99. Gain - The Number 5 Knob adjusts the Output Gain from the Compressor. Ranges from 0 to 6 (dB).

AutoYa

Like the YaYa, an AutoYa combines the characteristics of a Wah and a Flanger together creating an almost human vowel sound as if the guitar were saying Yah. The AutoYa automatically provides this animation by modulating the sound at an even rate. Parameter 1 - The Number 2 Knob adjusts the rate (Speed) of the modulation. Ranges from 1 to 99.
Parameter 2 - The Number 3 Knob adjusts the intensity of the AutoYa effect. Ranges from 1 to 99. Parameter 3 - The Number 4 Knob adjusts the throaty quality of the AutoYa effect. Ranges from 1 to 50. Mod Level - The Number 5 Knob controls the mix of wet and dry signal. Ranges from 0 (all dry) to 99 (all wet).

SynthTalk

SynthTalk is another effect exclusive to DigiTech. It makes your guitar seem to speak based upon the dynamics of your playing style. Parameter 1 - The Number 2 Knob adjusts the Attack of the synthesized voice. Ranges from 1 to 99. Parameter 2 - The Number 3 Knob adjusts the Release of the synthesized voice. Ranges from 1 to 99. Parameter 3 - The Number 4 Knob changes the characteristics of the various synth voices. Ranges from 0 to 99. Mod Level - The Number 5 Knob adjusts the sensitivity or the input signal required to trigger the SynthTalk effect. Ranges from 0 to 99.

Envelope Filter

The Envelope Filter is an automatic Wah effect that alters your sound based upon how hard the strings are struck. Parameter 1 - The Number 2 Knob adjusts amount of Wah sweep once the Wah is triggered. Ranges from 1 to 99. Parameter 2 - The Number 3 Knob adjusts the sensitivity or the input signal required to trigger the Wah effect. Ranges from 1 to 99. Mod Level - The Number 5 Knob controls the mix of wet and dry signal. Ranges from 0 (all dry) to 99 (all wet). The Number 4 Knob has no function when the Envelope Filter is selected.

Detune

A Detuner will make a copy of your incoming signal, take the copied signal slightly out of tune from the original, and mix the two signals together. The result is a doubling type of effect as if two guitars were playing the same part together. Parameter 1 - The Number 2 Knob adjusts the amount of pitch difference applied to the copied signal. Ranges from -18 to 18. Mod Level - The Number 5 Knob controls the volume of the detuned note. Ranges from 0 to 99. The Number 3 and 4 knobs have no function when the Detune effect is selected.

Pitch Shift

A Pitch Shifter copies the incoming signal, then shifts the pitch of the copied note to a different note. The shifted note is then mixed back with the original signal sounding as if two guitars were playing in harmony. Parameter 1 - The Number 2 Knob selects the interval of the shifted pitch. Ranges from -12 (12 semitones below) to 24 (24 semitones above). Mod Level - The Number 5 Knob controls the volume of the shifted pitch. Ranges from 0 to 99. The Number 3 and 4 knobs have no function when the Pitch Shift effect is selected.

RPx400 Setups RPx400 Setups

Setups Introduction

The RPx400 is equipped with four inputs and four outputs that can be configured several different ways for both live and recording applications. These configurations are selected in the DRUMS/SETUP row of the editing matrix using the five editing knobs. Settings include whether the Mic or Line inputs are routed through the RPx400s effects processing, which outputs have Speaker Compensation enabled, and which pair of outputs mic, line, and guitar processing are routed to. The USB 1-2 Source and USB 3-4 Source knobs are used for configuring how all inputs, guitar processing, and drum machine are routed via USB to the computer for recording applications.

Mic / Line Setups

The Mic and Line Setups are configurations for the mic and line inputs designed primarily for live performance applications. The RPx400 acts as a mixing device for mic and line sources, and can eliminate the need for a mixer when the RPx400s outputs are to be plugged directly into a full-range powered speaker system. When enabled, these inputs can be routed around or through the RPx400s effects processing and then mixed directly into the RPx400s 1/4 and XLR outputs. Both Mic and Line inputs have four settings that can be independently selected using the Mic and Line knobs in the DRUMS/SETUP row of the effect matrix. The configurations are as follows:
MICOFF / LINOFF - Mic and Line inputs are disabled. MICDRY / LINDRY - Inputs routed directly to RPx400s outputs, bypassing all effects processing. MICRVB / LINRVB - Inputs routed through delay and reverb effects of the current preset. MICFX / LINEFX - Inputs routed through all effects of current preset.

RPx400 Drums and MIDI

The RPx400s Drum machine samples are mapped so that they may be triggered by MIDI notes played from Pro Tracks. Each of the drum patterns programmed in the RPx400 has been programmed as a MIDI track in the Pro Tracks project file library. Note mapping for each of the RPx400s drum samples is as follows: MIDI Note Sample 36/C3.Kick 38/D3.Snare 42/F#3.Closed High Hat 46/Bb3.Open High Hat
Recording the RPx400 Drums
The RPx400s drum machine can be recorded using Pro Tracks. Each of the RPx400 drum patterns have been saved as pattern template files which can be selected from the Pro Tracks project file library for playback control of the RPx400s drum samples. To record the RPx400 drums using the pattern templates provided in Pro Tracks, follow these steps: 1. From the Pro Tracks menu bar, select File>New. The New Project File window will appear. 2. Select one of the DigiTech RPx400 drum templates and click the OK button. This will open up a new recording session. 3. On the RPx400, use the either USB 1-2 Source or USB 3-4 Source knobs to select drums. 4. Press the RECORD footswitch. The RPx400s display reads record. A new track is automatically inserted in the current session of the Pro Tracks software and recording on these tracks begins. 5. To stop recording, press the STOP/UNDO footswitch. You can use MIDI drum files for playing the RPx400 drum samples if you like as long as the events are mapped to the MIDI notes shown above. The drum samples of the RPx400 only respond to MIDI messages transmitted on MIDI channel 10, which is the default channel for General MIDI drums.

Playback Mix

The PLAYBACK MIX knob is an easy way to balance the RPx400s processing with playback from the Pro Tracks software using a single control. This function is only available when the RPx400 is connected to the computer via USB and Pro Tracks is up and running. To change the RPx400/Playback mix, follow these steps: 1. Start playback of a session from Pro Tracks. 2. Turn the playback mix knob to balance the level of RPx400 guitar processing and playback level. When the display reads USBMIX 0 indicates that only RPx400 signals will be heard. Rotating this knob clockwise, you will begin to hear the playback level increase. USBRPX50 indicates the RPx400/computer playback mix is a 50/50 mix of both signals. Continuing to rotate the knob clockwise will decrease RPx400 level. RPxMIX 0 indicates that only playback from the computer will be heard.

V-Switch Sensitivity

If you want to adjust the sensitivity setting of the V-Switch, follow steps 1 through 7 of Calibrating the Expression Pedal and then follow the steps listed below: 1. When the display reads VSWTCH, rock the Expression Pedal forward (toe down) and apply extra pressure on the toe of the pedal until the display reads DONE. 2. When display alternates between DONE (with the V-Switch sensitivity value in the numeric Display) and VSWTCHOn (or VSWTCHOf depending on whether the V-Switch is on or off), you can audition the VSwitch sensitivity by applying pressure to the toe of the Expression Pedal. 3. Rotate the Number 5 Knob to change the value of the V-Switch sensitivity. You can audition the new value by applying pressure to the toe of the Expression Pedal. 4. Once the sensitivity value is selected, press any footswitch. The RPx400 returns to Performance Mode and your settings are automatically saved.

Please refer to the system requirements section. How do I install USB drivers? Normally, if you follow the instructions in the installation CD, the installer will copy and activate them correctly. If you need to reinstall them, click on the USB option that appears when the installation CD is booted. If this still doesnt provide the desired results, try going to Options->Audio->Drivers and selecting only DigiTech USB1-2 In/Out. Then run the Wave Profiler in Options-> Audio->General. Finally, go back to Options->Audio->Drivers and then select DigiTech USB3-4 In Only. Can I record 24-bit audio? 24-bit audio recording will be available soon. Check http://www.digitech.com for updates. My mic signal sounds distorted. Adjust the mic level trim pot on the rear panel of the RPx 400. Also, adjust USB levels so the signal that is fed to the recorder is in the appropriate range. Can I turn off microphone phantom power? No, but it should not damage a typical dynamic mic because the phantom power is present on both the signal lines coming from (going to) the mic. Can I use third party plug-ins and soft-synths? Yes, DirectX compatible plug-ins and DXi SoftSynths.
My MIDI drum pattern doesnt play RPx 400 drums. The RPx 400 contains a limited drum kit so sometimes a drum pattern will require voices that are not available in the RPx 400. In some cases, you can transpose the note that a drum voice is mapped to in order to trigger a drum beat in the RPx 400. The RPx 400 drum notes are: Bb3 is the open Hi Hat F#3 is the closed Hi Hat D3 is the Snare C3 is the Kick Drum Where did my wave files go? Wave files all get saved to the folder specified in Options->Global, Audio Data. My waves are low in level. The recording signal level can be boosted using the USB1-2 and USB3-4 level controls. My waves are too high in level. The recording signal level can be lowered using the USB1-2 and USB3-4 level controls. Your amp level might be too high. Pro Tracks playback is louder than my guitar. You can adjust the mix of playback versus guitar by using the Playback mix knob. I get audio dropout while Im recording. Try increasing the latency slider in the audio settings. Try reducing the number of tracks in your project (mute won't help, you either have to "archive" the tracks, or delete them) Close any other open programs besides Pro Tracks check "task manager" to make sure there are no hidden programs running. Try reducing the number of plug-ins and soft-synths. Increase the amount of memory in your system. Get a faster hard drive. Put your audio data on a different hard drive from your OS and applications. Get a faster computer. Can I use the RPx 400 with other recording applications? Yes, as long as they support standard windows wave drivers (MME or WDM). Support for ASIO will come soon with new drivers. ASIO based applications are Cubase, Logic, etc. When I launch X Edit, it cant find the RPx 400. Make sure your drivers are loaded correctly and that the USB cable is inserted securely. See the section on driver installation.

I hear doubling of the playback. Input monitoring is probably active. Go to Options->Audio->Input Monitoring to disable. Its taking forever to install X Edit/Drivers. Microsoft.NET framework is required for X Edit to run on Windows PCs. It is a very large file and if it is not already present on a system, it will take a while to load. However in Windows 2000 systems, if McAfee Virus scanning software is installed, a security issue will cause.NET installation to halt. McAfee must be un-installed not just disabled in order for the.NET installation to proceed. I cant launch X Edit. This is usually caused by MIDI problems. Make sure your drivers are loaded correctly and that the USB cable is inserted securely. See the section on driver installation. My guitar sound is really bright. Activate speaker compensation for the desired output jacks. I dont hear guitar signal in headphones or XLR. You are probably using one of the Split modes. Change this selection with the output mode knob on the setup level of the matrix. My guitar sounds dark through my amp. De-activate speaker compensation for the output jacks that feed the amp. How can I keep the drums from playing through my amp? You can either turn the Drums off or switch to one of the two output modes SPLIT1 or SPLIT2 and send Guitar to your amp and drums to the PA. I am hearing mic/line inputs through my guitar amp. You can either turn off the Mic and Line inputs or switch to one of the two output modes SPLIT1 or SPLIT2 and send Guitar to your amp and everything else to the PA. How are signals routed through the RPx? Refer to the routing diagrams in the RPx400 Users Guide I cant access Learn-a-Lick. The USB cable must be disconnected in order to access Learn-a-Lick Bass, Mid and Treble controls are not working. When USB is connected, the Bass, Mid and Treble controls function as USB mix and level controls. The tone controls can still be accessed from the editing matrix or from X Edit.
Everything I record seems distorted. Your levels may be too high. Try lowering the amp level or USB level. How do I get my footswitches to do recording functions? Press the two right footswitches simultaneously to toggle from preset mode to recording footswitch mode. I get RECERR, ARMERR or DELERR in my RPx display. Make sure DigiTech RPx USB MIDI is selected in Pro Tracks Options->MIDI Devices. Make sure that Options->Control Surface is set to use DigiTech RPx USB MIDI. This sometimes also indicates an incompatibility between the drivers and the DigiTechRPx.dll file. See the section on driver installation. Pro Tracks wont launch. This was probably caused by interrupting the USB connection while in a previous Pro Tracks session. You must reboot your system to fix this problem. I dont hear playback from USB 3-4. Playback is only available on USB1-2. USB3-4 is used for additional track recording things like dry guitar, mic, drums, etc. How do I control drum level when Im playing back a MIDI drum track through the RPx? The drum level can only be adjusted after turning the Drums on. The middle knob controls the level. My drums didnt record. Drums can only be recorded on a separate track, not as part of a mix. To record drums, go to the setup level of the matrix and select Drums in USB1-2 or USB3-4. My line inputs didnt record. Dry line inputs can only be recorded on a separate track, not as part of a mix. To record line inputs, go to the setup level of the matrix and select DRYLIN in USB1-2 or USB3-4. Line with reverb or effects can be recorded as a mix with guitar. The Line selector must be set to either LINRVB or LINEFX. My mic didnt record. Dry mic can only be recorded on a separate track, not as part of a mix. To record mic, go to the setup level of the matrix and select MICDRY in USB1-2 or USB3-4. Mic with reverb or effects can be recorded as a mix with guitar. The Mic selector must be set to either MICRVB or MIC FX. I get dropout when I change presets during recording/playback. Dont change presets during recording/playback.

My mic/line inputs had dropout while I was recording. Changing presets while recording will cause dropout of mic and line audio to the computer. I cant send or receive MIDI CC data. If the system crashed while X Edit was running, then the RPx wouldnt have received the signal to exit that mode. Go into X Edit and then exit and the ccs should start working. What if I plug into a different USB jack on my computer? Windows should detect the new hardware and go through a driver installation process automatically but it will not load the DigiTech USB drivers that youll need for Pro Tracks and X Edit. For that, keep the USB cable connected to the new port and run the USB installer. Im adjusting amp type but tone controls keep popping up. This happens when MIDI data is echoed back to the unit by Pro Tracks. In Pro Tracks, go to Options->Project->MIDI Input and set Echo Mode to None.
