USING CLOCKWORKS FOR MAC OS X WITH THE MIDI TIMEPIECE AV 5
Making a connection
To r out e M I DI d i r e ctly from a MIDI device to any other, click the
source cable icon on the left and drag to the destination cable icon
on the right.
Connecting one input to multiple outputs
To c on n e c t an input to more than one output, make each
connection separately as described in the previous section. As a
shortcut, shift-drag from the input cable on the left over to the
first output, and then drag directly to each additional output on
the right. As you “touch” each output, it highlights and a
connection is made.
Selecting a connection
To s e le c t a c on n e c t i on , click the connection’s input cable icon on
the left or one of its output cable icons on the right.
Deselecting all connections
To d e s e l e c t a l l c on n e c tions, click anywhere in the middle of the
window between the two columns of cables.
Breaking a connection
To b re a k a c o n n ection, select the connection by clicking its cable
icon, and press the delete key.
Breaking one of several connections
Often, a device will be connected to several other devices. To
delete just one of the connections:
1 Redraw the connection you want to break.
2 Press the delete key to remove the highlighted connection.
The MTC In and MTC Out connections
The MTC In and MTC Out connectors represent MIDI Time
Code (MTC) routing to and from the interface 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 MTC Out port (on the left) to the desired device(s) on
the right.
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 (on the left) to the MTC In port (on the right).
Routing MTC to the computer port
From the factory, the MIDI Timepiece AV is programmed to send
MTC to the computer port, as shown in Figure 2. This connection
is required by any MIDI software that needs to slave to MTC
generated by the interface.
The MMC Out and MMC In ports
The MMC Out and MMC 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 (or redistributed by) the
MIDI Timepiece AV itself to another device, create a connection
from the MMC Out port to the desired device. Usually, you will
only have one such connection at a time, as only one device would
be triggered as the Time Code source. Note also that this
connection is not necessary, however, if you intend to send MMC
transport commands directly from computer software (or a
MMC hardware device) to a MMC device.
Figure 3: Routing MIDI Time Code from the MIDI Timepiece AV to other MIDI devices
connected to it.
Routing MMC from the computer to the interface
The MMC In port in the Routing tab represents MIDI Machine
Control input to the MIDI Timepiece AV itself. In other words, the
interface “listens” to MMC transport commands from any devices
(or computer software) connected to this port.
For MMC transport control of the interface from the computer, all
you need is the connection from the computer icon on the left to
the MMC icon on the right, as shown below in Figure 4.
Figure 4: The selected connection shown above is required when you want to control
your MOTU interface — and any devices slaving to it — from your sequencer or other
MMC software on the computer.
Direct MMC versus redistributed MMC
When the connection shown in Figure 4 is made, the MIDI
Timepiece AV “swallows” all MMC transport commands sent by
MMC software running on the computer, regardless of the MMC
device the messages are intended for (as determined by the MMC
device ID embedded in the messages). If you want to control a
MMC device from your computer, you have two choices:
1. bypass the interface’s MMC features,
2. or send the MMC transport commands to the MIDI Timepiece
AV i n s t e a d and have it redistribute them to the other MMC
device(s)
