M-AUDIO Biport 2x4s - Manual (Page 45)

or the driver is not installed at all. Turn back a couple of pages and fol-
low the instructions for Windows Driver Installation.
SOLUTION 2: The sequencer program is not set up to use the BiPort
driver. This must be done from within the program itself. Make sure the
BiPort input and output devices are selected for use by your sequencer
program.
SYMPTOM: The unit works fine with some of my programs but does-
n’t work with others.
SOLUTION: There is probably a set-up problem with the program that
isn’t working. It is likely that you haven’t selected the BiPort driver
from within your application.
SYMPTOM: The BiPort 2x4s driver is properly installed but I’m not
getting any sound when I run my sequencer.
SOLUTION 1: Your Windows application must select the BiPort 2x4s
as its MIDI Input and Output device. This is done from within the appli-
cation itself.
SOLUTION 2: The BiPort does not produce sound. Instead it connects
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 BiPort.
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
BiPort, click Properties, and then click the Midiman 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 turn-
ing 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 soft-
ware.
