Troubleshooting
Is the volume on the PC-80 itself set appropriately?
Use the PC-80’s master volume knob to adjust the volume.
Could the Speaker On/Off setting be turned off?
If the PC-80’s Audio System setting Speaker On/Off is turned off, the output from the PC-80’s speakers will be
muted. Turn the speaker setting on. ( ➔ “SPEAKER ON/OFF” (p. 87))
Did you connect/disconnect the USB cable or cycle the power to the PC-80 while
your software was running?
You must close all software that uses the PC-80 before powering off the PC-80.
If you start up your computer with the PC-80 connected, operation may become unstable for some computers.
In this case, connect the PC-80 after starting up your computer.
Could your computer have entered Standby (Suspend) or Sleep mode?
After your computer wakes up, close all software that had been using the PC-80, and then cycle the power to
the PC-80.
Have you specified the audio and MIDI data output destination in the operating
system?
Depending on the software you are using, you may need to specify the PC-80 as the audio data output
destination for your computer. ( ➔ “Input/output device settings” (p. 100))
Are the faders of the Windows volume control raised?
Adjust the faders of the Windows volume control.
For details, refer to the Windows operating manual or on-line help.
Is the main volume level of the Macintosh raised?
In System Preferences ➔ Sound, make sure that the Output volume slider is raised (set toward the right).
Is the driver installed correctly?
If you’re using Windows, you’ll need to install a driver in order to play back audio/MIDI data via the PC-80.
( ➔ “Installation and settings (Windows)” (p. 16), “Installation and settings (Macintosh)” (p. 29))
Are you running numerous software programs?
An error message may appear if numerous software programs are running simultaneously. If this occurs, close
the software you are not using.
In Windows, a program is still running if it remains in the taskbar even after you close its window; close any
unneeded software shown in the taskbar.
Do the recording and playback sample rates match?
Use the same sample rate for recording and playback.
Could the PC-80’s sample rate be set to “96 kHz recording”?
With this setting, only recording is possible. You won’t be able to play back sound from the computer.
Conversely, recording is not possible if the sample rate is set to “96 kHz playback.”
Are your input/output devices connected correctly?
In order to play back audio/MIDI using the PC-80, you must make the appropriate input/output device
settings. For details on making these settings, refer to “Input/output device settings” (p. 100).
Could the PC-80 have been connected when you started up the computer?
Start up the computer with the PC-80 disconnected, and then connect the PC-80.
Depending on the type of computer you are using, starting up the computer when the PC-80 is already
connected may cause operation to be unstable. In this case, start up your computer and then connect the PC-80.
