COMMON PROBLEMS AND SOLUTIONS
MTP/Express Console keeps displaying the
following message even though the Express XT is
connected (Macintosh Version).
Check the computer button on the front panel. If
the problem is not simply that the MIDI
Express XT is switched off or has a loose cable, it
may be that communication between MTP/
Express Console and the MIDI Express XT has
been disrupted somehow. If you have a drum
machine or sequencer connected to it, be sure that
it is not sending MIDI sync to the Express XT. If so,
turn off the drum machine while launching the
MTP/Express Console and then mute real time
data on its input cable. To reestablish the
connection between MTP/Express Console and
the Express XT, switch off the Express XT, quit the
Console, let the box sit for a moment, and then
turn it back on again and try opening the Console.
Always return to the simplest possible scenario if
you just can't seem to get to the bottom of the
problem. Starting from the ground up usually
either corrects the problem or gives you valuable
insight into how to solve it.
The LEDs on the front panel of the MIDI
Express XT blink erratically as soon as I turn it on
and the box doesn't operate properly.
This is a symptom that MIDI software running on
the Macintosh is set to a different communications
speed than the MIDI Express XT. To get things
back to normal, switch the box off and set the
MIDI software interface settings correctly and then
power the Express XT on again. To prevent this
from happening again, be sure that the MIDI
software you are running is set to 1 MHz). This
type of "light show" can also be caused by INITs
and other Macintosh software that sends
miscellaneous data out the Macintosh serial ports
when the Macintosh boots up. In general, it is a
good idea to leave the MIDI Express XT turned off
until after the Macintosh has booted up. If the
blinking is regular but faint, its just harmless active
sensing from the synth.
The MIDI Express XT will not sync to SMPTE.
Make sure the Express XT is in LTC QuikLock
mode. (This setting is in the Sync Controls window
in the MTP/Express Console software.) Make sure
that the SMPTE IN cable is firmly seated and
connected to the appropriate output on the tape
deck. Observe the LTC LOCK light. Is it flickering
quickly and steadily? If so, the MIDI Express XT is
locked to tape and the syncing problem is probably
related to MIDI. If not, check the level of the
SMPTE: it should be approximately –3 VU; then,
try boosting or attenuating the SMPTE signal from
the tape. You may even want to try recording some
fresh SMPTE and locking to it.
The SMPTE Reader window just sits there when
the MIDI Express XT is syncing to SMPTE, even
when its LTC LOCK LED shows that it seems to be
locked up just fine.
This most likely means that MIDI Sync is not being
routed to the Macintosh. Check the Cable Routing
window to make sure the Express XT Sync Out
port is connected to the Mac. Also note that the
SMPTE display in the SMPTE Reader and Sync
Controls windows will only display incommoding
