Notes On Midi Synchronization - Yamaha MDF3 Owner's Manual

Notes on MIDI Synchronization

The MIDI clock of a sequencing device to be synchronized with the MDF3 must normally
be set to a value opposite that of the MDF3. If you want the MDF3 to control the playback
tempo, select the "int." sync mode and set the other device to use the MIDI clock. If the
other device is to be the master, reverse these settings. In either case, you should also use
the "MIDI control" function to enable the MDF3's transmission and reception of MIDI
system control messages. When synchronizing the MDF3 to another device, both the
"Sync mode" and "MIDI control" functions must be set to appropriate values.
The possibilities for combining these settings are summarized in the table below.

Note:
If an external sequencer or other device connected to the MDF3 retransmits the MIDI data it
receives (using a MIDI echo function), avoid a looped MIDI connection or set the MDF3's MIDI
control function to "off". Otherwise, the MDF3 may malfunction.
