Note: If your devices can follow MTC (MIDI Time Code), you should leave this option
unchecked, and make use of Logic’s MTC functions.
MIDI Time Code (MTC): Pickup Delay
This parameter should generally be set to zero to ensure the quickest possible pickup
time while Logic is in MTC sync mode. There are, however, some devices which seem to
transmit imprecise MTC commands when first started. As a result, sync might not be
perfectly reliable, and there could be an offset every time synchronization is
established. In such situations, you can set a delay for MTC pickup, and Logic will ignore
the initial MTC commands. A (frame) value of 25 to 30 corresponds to a delay of about
a second, depending on the frame rate. Use this parameter when synchronized to hard
disk recorders and other devices, if the sync doesn’t appear to be consistent.
MIDI Time Code (MTC): Transmit MTC Delay
This parameter allows you to delay the transmission of MIDI Time Code. Negative
values result in MTC being transmitted earlier. This facility enables you to compensate
for any reaction delays (to incoming MIDI Time Code) in external MTC slaves.
MIDI Sync Song Settings
Pressing this button will launch the MIDI Sync Song Settings window.
MIDI Preferences: Reset Messages
This page is only left for compatibility reasons with older MIDI hardware. Logic handles
MIDI Reset Messages automatically and intelligently, so you should generally make sure
that all options are switched off (this the default).
All selected checkboxes will send a reset message for the selected controller type to all
MIDI outputs. This reset message will be sent on Cycle jumps and when playback
begins, but the use of these options shouldn’t be necessary.
