Troubleshooting - Yamaha A4000 Owner's Manual

Troubleshooting

If you encounter problems such as no sound output or abnormal behavior, verify the connections
before checking the following. If you are using the A5000/A4000 Editor for Windows, refer to the
XGworks(lite) owner's manual too.
<Macintosh>
The printer port is not recognized.
• The printer port will not be recognized if AppleTalk
is ON. Note that with some Macintosh models,
AppleTalk is automatically enabled when starting
up.
• Verify that the "Printer" checkbox has been checked
in the OMS MIDI Setup window.
The modem port is not recognized.
• On some Macintosh models such as the Performa
series, the modem port cannot be used and only the
printer port is available.
• Verify that the "Modem" checkbox has been
checked in the OMS MIDI Setup window.
No MIDI In/Out data
• In the OMS Port Setup, is MIDI In/Out set to
"unknown"? If you change the OMS ports or setup,
the OMS output ports have to be set accordingly in
A5000/A4000 Editor's OMS Port Setup window.
Choose the appropriate receiving device.
• Is OMS using the same port as that connected to
the cable? Open the OMS MIDI Setup window and
verify that the checkbox for the relevant port has
been checked.
• If the port and setup assignments are frequently
altered, OMS may be unable to easily recognize the
serial port. Reboot the Macintosh, set up OMS
correctly, then start up the A5000/A4000 Editor.

the MIDI In has been properly assigned (Page 26).
