DigiTech RPX400 User Manual

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 Windows 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.
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 USB Driver installation.
I hear doubling of the playback.
• Input monitoring is probably active. Go to Options->Audio->Input Monitoring to disable.
Bass, Mid and Treble controls are not working.
• When USB is connected, the Bass, Mid and Treble controls function as Playback Mix, USB 1-2 Level, and USB
3-4 Level controls. The tone controls can still be accessed from the editing matrix or from X Edit.
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 Source or USB3-4 Source.
• Mic with reverb or effects can be recorded as a mix with guitar. The Mic setup must be set to either
MICRVB or MIC FX.
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 Source or USB3-4 Source.
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 Source or USB3-4 Source.
• Line with reverb or effects can be recorded as a mix with guitar. The Line selector must be set to either LINRVB
or LINEFX.
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.
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 – like dry guitar, mic, drums,
etc.
