When your Express interface operates in MTC
mode, it locks to any MTC coming from your
computer. In doing so, however, it also “swallows”
the MTC coming from the computer. If you
attempt to transmit MTC from your MIDI software
to a specific MIDI device in your studio, it won’t
reach the MIDI device because it will get read and
“swallowed” by your Express interface. Since
computer-generated MTC is not as stable as other
forms of time code, you are better off doing just the
opposite: send MTC from your Express interface to
the computer, and if necessary, control your Express interface from your computer software via
MIDI Machine Control as demonstrated in
Figure 4-4 on page 22.
If you absolutely must transmit MTC from your
computer for some reason, See “Routing MTC to
the Micro Express” on page 38 (for micro express
users) or “Routing MTC to the MIDI Express XT”
on page 58 (for Express XT users) for important
information about routing MTC to your Express
interface. If you need to send MTC to other devices
as well, you can route it to them as demonstrated in
Figure 6-9 on page 38 (for micro express users) or
Figure 7-9 on page 58 (for Express XT users).
