USING CLOCKWORKS FOR MAC OS X WITH THE MIDI TIMEPIECE AV 8
THE MAPPINGS TAB
The Mappings tab controls the channelizing of MIDI data on all
MIDI IN and MIDI OUT cables. With complete flexibility, this
window can switch data from its current MIDI channel to any
other channel immediately when the data either enters or exits the
MIDI Timepiece AV.
Figure 10: The Mappings tab. Use the Input/Output and Cable menus to display the
desired input or output cable. For each channel (row), click the check box corresponding
to the channel you wish to remap it to.
Mapping basics
A simple way to think of channel mapping is this: imagine that
each MIDI IN or MIDI OUT port connected to the MIDI
Timepiece AV has a filter just inside the socket. MIDI data enters
the filter on one channel and as it passes through the filter, it gets
switched to a different channel.
On a MIDI IN port, data enters on a given channel. But before it
goes anywhere else, either to the computer or to a MIDI OUT
cable, the Channel Map window can switch the data to a different
MIDI channel.
On a MIDI OUT cable, data exits the interface. But before it does,
the Channel Map window can switch the data to a different
channel.
Using channel mapping
Channel Mapping like this is useful in many different situations.
For example, you may have a MIDI keyboard that only transmits
data on MIDI channel 1. If you want to transmit its data on a
different channel, you can map channel 1 on the keyboard’s MIDI
IN cable to any other MIDI channel. To the rest of the network, it
will then appear as if the keyboard is transmitting on the new,
destination channel.
Muting and remapping
For information about when muting occurs before channel
mapping and vice versa, see “Muting and remapping” on page 7.
SYNCHRONIZATION AND MIDI MACHINE CONTROL
The Sync tab and the sync-related controls at the top of the
window give you control over the MIDI Timepiece AV’s sync and
MMC transport control features.
Figure 11: The synchronization and MIDI machine controls.
Transport controls
The transport controls are just like standard tape deck transports.
From left to right, they are: rewind, stop, play, pause and record.
These buttons control the time code generated by the MIDI
Timepiece AV when it is in any master sync mode in which it
controls the current address (SMPTE location), such as
Internal
mode. The record button triggers recorders that are connected to
the MIDI Timepiece AV and that have been armed for recording.
(See “The MMC record mode menu” on page 9.)
Figure 12: ClockWorks transport controls.
SMPTE Readout
The SMPTE Readout provides a running update of the time code
being generated or converted by the MIDI Timepiece AV. This
running update is made possible by MIDI Time Code (MTC)
generated by the MIDI Timepiece AV and routed to the computer.
If the SMPTE Readout is not responding, try using the
Reset to
Factory Settings
command in the File menu.
Cueing to a specific frame
The SMPTE readout shows the MIDI Timepiece AV’s current
frame location in hours: minutes: seconds/ frames. You can also
type in any frame location you wish into the SMPTE Readout to
