832 Synchronizing Your Gear
SMPTE/MIDI Time Code Synchronization
to MIDI Sync. Most devices have a Clock option that should be set to
External or MIDI.
If SONAR does not respond to MIDI Sync as a slave device, verify that your
external devices are configured correctly to transmit MIDI Sync. Remember
that only one external device can be used as the master clock source.
SMPTE/MIDI Time Code Synchronization
SMPTE/MIDI Time Code Sync (SMPTE/MTC) is another method of
synchronization that lets SONAR act as a master or slave to external
devices. SONAR can send or receive SMPTE/MTC messages to or from
external devices that can generate or receive MTC. SONAR can send MTC
on multiple output ports simultaneously.
SMPTE/MTC is a position and timing reference that indicates the current
location in the project and how quickly the project should be playing. Time
code labels the position in a project in hours, minutes, seconds, and
frames. The speed of playback is indicated by a frame rate.
Time code is recorded onto tape using a device called a time code
generator. The process of recording a time code signal onto a track is
called striping. Normally, the start of a tape stripe has a particular time,
expressed in hours, minutes, seconds, and frames. For example, the tape
stripe might start at 00:00:00:00, 01:00:00:00, or any other time. The
material recorded on the tape usually starts anywhere from 10 seconds to
several minutes after the start of the time code. Sometimes, the tape stripe
starts at a time like 00:59:50:00, and the material starts 10 seconds later, at
01:00:00:00.
When you create a new SONAR project, by default the project is configured
so that the beginning of bar 1 is synchronized with a time code of
00:00:00:00. If the starting point of the material on your tape or external
project is not 0, you need to enter an offset to tell SONAR the time code
that corresponds to the start of the project.
To Enter an Offset
1. Select Options-Project.
The Project Options dialog appears.
2. Click on the Clock tab.
3. In the Clock tab, enter an offset in the SMPTE/MTC Offset field. To
enter an offset of 15 seconds, type 0,0,15 and hit enter. The SMPTE/
MTC Offset value should now be 00:00:15:00 or 15 seconds.
