Synchronization settings
General Synchronization settings in Logic Pro
General Synchronization settings are available only when Show Advanced Tools is
selected in Advanced preferences.
These settings are used when Logic Pro is being controlled by another device and acting
as a MIDI clock receiver.
• Sync Mode pop-up menu: Defines how Logic Pro syncs with the other device.
• Internal: Selects the internal timer of Logic Pro, with Logic Pro transmitting MIDI
clock. External devices can be synchronized via MIDI clock or MTC.
• MTC: Selects MIDI Time Code mode, with Logic Pro following incoming MTC. MIDI
timecode can either arrive at a MIDI In port, or be generated by a MIDI interface that
translates it from incoming SMPTE timecode—the Unitor8, for example.
• Manual: Selects Tempo Interpreter mode, with Logic Pro receiving MIDI clock
impulses that are recognized as valid beats by the Tempo Interpreter. The
parameters that control how Logic Pro responds to Tap Tempo commands can be
found in the Tempo Interpreter window.
• Auto-enable External Sync and Tap Tempo checkbox: When selected, Logic Pro
transmits MIDI clock until it receives a synchronization signal—either in the form of
MTC, or from the Tempo Interpreter.
Logic Pro automatically locks to the first synchronization signal it receives.
Important: Make sure that different synchronization signals don’t arrive simultaneously;
remember that only one device should transmit timecode.
• Frame Rate pop-up menu: Defines the frame rate, which applies to both transmitted and
received timecode.
Note: In drop frame formats, certain frames are left out. (This follows a regular pattern.)
To distinguish between formats, those without dropped frames are sometimes referred
to as NDF or non–drop frame.
