pressing Enter will bring up the appropriate
window (Sync and ADAT settings will be covered
shortly).
You can also open the Advanced MIDI window by
clicking the button in the lower left-hand corner of
the window as shown in Figure 10-1 on page 83.
Accessing the Filter and Channel Map windows
When an input port source is selected, the filter and
channelize buttons will become available and
pressing them will open a Filter or Channel Map
window for the selected port (event filtering and
channelizing will be covered shortly). As with the
sources, you may access the destination Filter and
Channel Map windows for each selected
destination port. You may open as many Filter and
Channel Map windows as you wish, but there will
always be only one Filter and one Channel Map
window for each port.
For example, if you open the Filter window for
input 3 and then it becomes hidden behind other
windows, selecting input 3 in the routing window
and pressing the filter button again will cause the
appropriate window to be “brought to the top”--
another one will not be opened. Alternately, the
Window menu will always contain a list of all the
open Console windows from which you can select
one to activate.
The Sync In and Sync Out icons
The Sync In and Sync Out connectors represent
MIDI Time Code (MTC) routing to and from the
MIDI Timepiece AV itself. If you would like to send
MIDI Time Code from the MIDI Timepiece AV to
devices connected to its MIDI Out ports, create a
connection from the Sync Out icon to the desired
devices, as shown in Figure 10-9.
Figure 10-9: To send MIDI Time Code (MTC) generated by the MIDI
Timepiece AV to other devices in your network, make a connection
from the Sync Out icon to the desired devices as shown here. In this
example, MTC is being sent to the Akai DR8 and Roland VS-880 hard
disk recorders, as well as a JL Cooper CuePoint MMC controller.
Routing MTC to the MIDI Timepiece AV
If you would like to slave the MIDI Timepiece AV
to MIDI Time Code generated by another device,
make a connection from the device’s source cable
to the Sync In icon. You’ll also need to set the MIDI
Timepiece AV MASTER SYNC mode to MTC or
MTC/VIDEO. (Please note that MTC mode is not
recommended because other forms of SMPTE
provide a more stable time base. For details, see
“Advice about choosing a time base master” on
page 118.)
Sync between the MIDI Timepiece AV and ADAT
Synchronization and transport control between
the MIDI Timepiece AV and ADATs connected to
its ADAT Sync Out icon is “hard-wired” and is
therefore not represented graphically in the MIDI
Routing window. The ADAT ports have no impact
on the AV’s control over ADATs.
The Transport Out and Transport In icons
The Transport Out and Transport In ports provide
routing of MIDI Machine Control (MMC)
transport commands to and from the MIDI
Timepiece AV itself. For example, if you would like
to send MMC transport commands generated by
