Synchronization

CHAPTER 8
OVERVIEW
This chapter explains how to use your MOTU Express
interface to synchronize computer software and other
devices to an audio tape recorder (ATR), video tape
recorder (VTR), or other time code sources using SMPTE
time code. It also explains how to generate SMPTE (a
process commonly referred to as striping).
This chapter also explains how to:
Slave your Express interface and other devices to MIDI
■
Time Code
Measure incoming time code to see how fast or slow it is
■
Solve various SMPTE synchronization problems

IF YOU ARE NEW TO SMPTE SYNC

If you are not familiar with the process of synchronizing
with SMPTE time code, see Appendix B, "SMPTE
Synchronization Basics" page (139)before reading this
chapter. It provides a definition of SMPTE time code and
an explanation of how it is used for synchronizing MIDI
devices to audio and video equipment.

ACCESSING SYNC SETTINGS

You can access the sync settings in your MOTU interface
via ClockWorks. See "Synchronization and MIDI
Machine control" on page 41 and "Sync tab settings" on
page 44 for details. (If you are running Mac OS 9, see
"Sync and MIDI Machine Control" on page 78 and
"SMPTE Reader" on page 86.)

SYNCING YOUR EXPRESS INTERFACE TO SMPTE

Your Express interface ships from the factory ready to lock
the computer to SMPTE time code via the MIDI Time
Code (MTC) routing shown below:
