Setup of the VF80
Because the MIDI clock and song position pointer will
be output from the VF80, set the SETUP mode “MIDI
sync signal output setting” to “CLK.”
Refer to page “126”, SETUP mode “MIDI sync signal output
setting” for correct operating procedures.
The meter in the desired bar can be set by “Time
signature setting” of the SETUP mode.
Refer to page “122”, SETUP mode “Time Signature Setting”
for operating procedure.
Tempo in the desired bar can be set by “T empo setting”
of the SETUP mode.
Refer to page “124”, SETUP mode “Tempo Setting” for
operating procedure.
Set the SETUP mode “Metronome setting” to “On” if
click sound is to be output according to the setup
tempo map.
Refer to page “125”, SETUP mode “Metronome setting” for
operating procedure.

Confirming the MIDI clock sync
During recording and at playback following the
recording, the time base (BAR/BEAT/CLK) is displayed
in accordance to the setup tempo map, and the MIDI
clock and song position pointer is also output.
Confirm that the travel position (BAR/BEAT/CLK) of
the VF08 and the travel position of the synchronized
MIDI sequencer are matched.
If correct sync cannot be obtained, re-check the
connections/cables and setting of both equipment.
<Note>
In the VF80, the “ABS 0” position is set at “-002BAR/1BEAT
/00CLK.” This setting is made in consideration of the
time required (it will not sync immediately) for the MIDI
sequencer, etc. to enter into sync. As a result, if the VF80
is played back from ABS 0 (LOCATE ABS 0), sync will be
completed by the time it reaches the first bar, and will
thus synchronize from head of the tune.
Press the [TIME BASE SEL] key, and then change the
time base display to BAR/BEAT/CLK.
Various ways of recording can be conducted while
synchronizing the VF80 and the MIDI sequencer with
the MIDI clock.
Executing of recording
MTC sync/MIDI machine control system
The following will explain synchronization by the MTC (MIDI time code) output and the computer controlling
system using MMC (MIDI machine control). In this system, the VF80 will be the master and the computer (with
sequence software) will be the slave. The VF80 will attach any desired offset (time difference) against ABS time
(absolute time) and output it as MTC in any desired frame rate. It can also carry out the proper operation upon
receiving an MMC from outside. In this case, because the VF80 can setup a DEVICE ID number by the SETUP mode
“MIDI Device ID Setting” menu, a multiple number of the VF80’s can be separately controlled by changing the DEVICE
ID numbers in the transmitted message from the computer.
