RPx400 Trouble Shooting Guide
Can I use the RPx 400 USB Capabilities with Windows 98, ME, or Mac OS 9.X?
• Drivers will be available soon. Check http://www.digitech.com for updates.
Audio playback from Pro Tracks has pops and clicks.
• Try the Wave Profiler under Options->Audio. This seems to fix most problems.
Otherwise, try using MME drivers in the Options->Audio->Advanced, Driver Mode
selection. These are the safest drivers but also have the most latency.
• Try increasing the latency slider in the audio settings.
Hands-Free recording on RPx 400 doesn’t work or has stopped working.
• If it was working at one point but has stopped working, try exiting Pro Tracks and then
restarting it (make sure to save your project).
• Cycle power to the RPx 400 before entering Pro Tracks or X Edit.
• If it has never worked at all, there is a problem with USB MIDI. The most probable
causes are using incorrect or incorrectly installed drivers and/or .dll or a bad USB
cable.
• See the section on driver installation.
I can’t hear audio playback from Pro Tracks.
• If the ‘Reamp’ mode in the RPx 400 is active try switching to a different mode like
‘Stereo’.
• Make sure the faders in Pro Tracks are turned up.
• Check that the tracks you want to playback are un-muted.
• Go to Options->Audio->Drivers and under output drivers, select ‘DigiTech USB 1-2
In/Out’ and de-select everything else.
• See the section on driver installation.
I get computer system sounds through my RPx 400.
• To disable computer sounds from going to the RPx 400, go to the ‘Sounds and Audio
Devices’ section of the ‘Control Panel’ and select a default playback device other than
DigiTech USB.
My RPx 400 doesn’t record to Pro Tracks.
• Go to Options->Audio->Drivers and under input drivers, select ‘DigiTech USB 1-2
In/Out’ and ‘DigiTech USB 3-4 In Only’ De-select everything else.
• Make sure the proper drivers are installed.
• See the section on driver installation.
• For an initial track, make sure ‘Reamp’ mode in the RPx 400 is not used.
I can’t get Reamping to work.
• See the section on reamping in the RPx400 User’s Guide.
• Most difficulties stem from source routing problems. A quick and simple way to do
reamping is to solo the dry track, select reamping and hit record. You won’t hear
anything except the reamped track but it can be mixed with the rest of the tracks after
it’s recorded.
Pro Tracks intermittently locks up.
• 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.
• 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 doesn’t 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 doesn’t 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 I’m 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 can’t 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.
It’s 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 can’t 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 don’t 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 User’s Guide
I can’t 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 won’t 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 don’t 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 I’m 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 didn’t 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 didn’t 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 didn’t 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.
• Don’t 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 can’t send or receive MIDI CC data.
• If the system crashed while X Edit was running, then the RPx wouldn’t have received
the signal to exit that mode. Go into X Edit and then exit and the cc’s 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 you’ll need for Pro
Tracks and X Edit. For that, keep the USB cable connected to the new port and run the
USB installer.
I’m 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’.
