to external MIDI devices that do produce sound, like a MIDI synthesizer. Make
sure that external MIDI device is properly set up and connected to the
MIDISPORT.
SOLUTION 3:
The driver may be disabled. Go to Settings | Control Panel |
System | Device Manager, then open up the list under “Sound, video and game
controllers” by clicking on the “+” sign. Highlight the MIDISPORT, click
Properties, and then uncheck “Disable in this hardware profile.” If using the
serial port drivers, click the Driver Settings tab to view the settings that you have
selected. If the COM port is set to “Disable,” then select the proper COM port.
SYMPTOM:
My keyboard shows “MIDI Data Error,” or “MIDI Buffer Full”.
SOLUTION:
Check your MIDI cables and MIDI connections. Be sure the cables
are plugged in all the way. If the problem persists try new cables.
SYMPTOM:
MIDI is being sent and received properly but when I play my
sequencer it lags and bogs down.
SOLUTION:
Make sure you don’t have a MIDI feedback loop. Try turning the
“Local Control” on your keyboard to OFF if it is being used both as a controller
and as a sound module. A MIDI feedback loop can also occur if the MIDI Out of
the interface is somehow connected back to the MIDI In through some external
device. This can be avoided by turning off the MIDI Thru on either your
keyboard or in the application software.
Serial Port Trouble-Shooting
SYMPTOM:
The diagnostic program’s Internal Hardware Test reports “FAIL
— Interface Not Found.”
SOLUTION 1:
The MIDISPORT is not set to the proper mode.
SOLUTION 2:
The Serial Port, IRQ and/or Address settings in the diagnostic
program probably do not match the actual IRQ and Address setting of your
serial port. Set them to the correct value(s).
SOLUTION 3:
Make sure the MIDISPORT is properly connected to your
computer, and to the proper COM/Serial port. If your PC COM port is
conflicting with your modem, try the other COM port. For Macs, the modem
port is more desirable than the printer port.
SYMPTOM:
The diagnostic program’s Transmit/Receive Test fails.
SOLUTION:
Either you forgot to install the MIDI loopback cable, or the ports
you’ve physically looped-back have not been properly specified in the
diagnostic program. This test transmits MIDI data out one port and then verifies
that it can be properly read into another.
SYMPTOM:
The diagnostic program’s SMPTE I/O Test fails.
SOLUTION:
You may have forgotten to connect the board’s SMPTE In
connector to the SMPTE Out connector using a 1/4” phone cable. This test uses
the cable to write SMPTE back into the unit and verify that it can be properly
read.
