M-AUDIO MM401 - Manual (Page 13)

address/port and interrupt/IRQ to match the settings on the
MM-401.
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 lugs and bogs down.
SOLUTION:
First, make sure you don’t have a MIDI feedback
loop. A MIDI feedback loop can occur if the MIDI Out of the
interface card is somehow connected back to the MIDI In. This
can be avoided by turning off the MIDI Thru on either your key-
board or in the application software.
If this is not the case your computer may be too old and slow to
handle the flow of data. Are you running on an old 4.77 Mhz
computer? If so, you may need to purchase a sequencer program
that runs the MM-401 in Intelligent mode to avoid this problem.
SYMPTOM: I’m a programmer and want to program for the card.
Do you have any information or drivers for the card?
SOLUTION
: Driver software for the card has been provided on
the factory diskette. Check the disk directories for information
on this. You can also contact MIDIMAN by mail, phone, or fax.
