MTC sync/Machine Control system
This section explains a synchronization system controlled by a computer using MMC (MIDI Machine Control) and
controlled by MTC (MIDI time code) output from the FD-8.
The FD-8 adds a given offset value to the ABS time on the disk and outputs the information as MTC of a given
frame rate. In addition, the FD-8 can receive external MMC and Fostex System Exclusive Message (FEX) to perform
certain operations. Changing the device ID number included in the messages transmitted from the computer
allows you to control various operations on the FD-8 individually. Use the “Setting the MIDI device number”
menu in SETUP mode to set the device ID number.
• Initialize the FD-8.
• If multiple Programs exist, select the desired Program first.
Connecting an external device
1. Connect the MIDI IN jack and MIDI out jack to the MIDI OUT/IN jacks of the computer (using a MIDI interface).
The computer should be running sequence software that supports MMC and MTC.
2. Set the sequence software to MTC slave mode and MMC output mode, and select the desired MTC frame rate.
3. Connect the MIDI sound sources and effect units accordingly, in the manner as explained in the “MIDI clock
sync system” section.
Setting MIDI SYNC OUT
1. Set the MIDI sync signal to be output to “MTC (Mtc)” in the “Setting MIDI sync output signal” menu in SETUP mode.
At this time, select [Mtc] for Time Base for convenience.
• Refer to page 103 for more information on SETUP mode.
Setting MTC OFFSET
1. Set the time offset from the ABS time (less than six hours) in the “Setting an MTC offset value” menu in SETUP mode.
• See page 104 for more information.
Setting a frame rate
1. Select the same MTC frame rate as that for the sequence software in the “Setting an MTC frame rate” in SETUP mode.
• See page 104 for more information.
Setting the device ID number
1. Set the same device ID number as the MMC device number for the sequence software and the FEX device
number in the “Setting the device ID number” menu in SETUP mode.
You do not set a number if the sequence software transmits [7Fh], which means [ALL DEVICE].
• See page 112 for more information.
Checking synchronization and Machine Control
1. Operate the FD-8 in play mode, and check to see if the sequence software synchronizes to the MTC output from the
FD-8.
Check to see if the FD-8 plays, stops, and locates points correctly when it is controlled from the computer.
