Determine if MMC commands should or should not be transmitted when using the
Logic Pro control bar buttons. MMC commands are used for remote control of MIDI-
controlled tape machines. See MIDI Machine Control in Logic Pro.
Open the Synchronization settings. See General Synchronization settings in
LogicPro.
Open the tempo editors. See Logic Pro tempo overview.
View the frame rate of incoming MIDI timecode
In Logic Pro, click the upper (MIDI In) section of the MIDI Activity display while receiving
an external synchronization signal.
MTC interpretation in Logic Pro
The MIDI standard supports four of the seven commonly used timecode formats: the 30fps
and 29.97fps (frames per second) formats are not differentiated in the MIDI specification.
Logic Pro needs to determine the intended format of incoming MTC (MIDI Time Code) and
interprets it as follows:
23.976fps is interpreted as 24fps.
24fps is interpreted as 24fps.
25fps is interpreted as 25fps.
29.97fps is interpreted as 29.97fps.
29.97fps drop frame is interpreted as 29.97dropfps.
30fps drop frame is interpreted as 29.97dropfps.
30fps is interpreted as 29.97fps.
Note: MIDI Time Code (MTC) is the MIDI equivalent of the audio-based SMPTE (Society of
Motion Picture and Television Engineers) timecode format.
Manually set a frame rate
In Logic Pro, choose a frame rate in the File > Project Settings > Synchronization >
General > Frame Rate pop-up menu. This setting overrides the automatic detection and
interpretation of frame rates.
