Connecting to external equipment
Connect the VF80 MIDI IN/OUT to the computer (with
MIDI interface) MIDI IN/OUT.
MMC/MTC complied sequence software is activated in
the computer.
Setup of external equipment
Setup the following in the sequence software.
* Set to MTC external sync mode (EXTERNAL SYNC).
* Set for output of MMC.
* Set to the desired MTC read out frame rate.
* Set start time of the tune (which MTC time is to be the first
bar). Refer to precaution in regards to MTC offset, farther
on.
For details, refer to Owners Manual of the external
equipment.
Setup of the VF80
Because MTC will be output from the VF80, set to “MTC”
the SETUP mode “MIDI sync signal output setting.”
Refer to page “126”, SETUP mode “MIDI sync signal output
setting” for operating procedure.
Set a random offset time by the SETUP mode “MTC
offset time setting.”
Refer to page “127”, SETUP mode “MTC offset time setting”
for operating procedure.
In the SETUP mode “MTC offset mode setting,” whether
the MTC offset time setup in Step 2 should be output
(ABS) at the ABS 00m 00s 00f 00sf position or at the
001BAR 1BEAT 00CLK (bar, signature) must be
selected.
Refer to page “127”, SETUP mode “MTC offset mode
setting” for operating procedure.
Setup to the same frame rate as that setup by the
sequence software by “MTC Frame rate setting” of the
SETUP mode.
Refer to page “126”, SETUP mode “MTC Frame rate setting”
for operating procedure and details.
Set to the same figure as the sequence software MMC
device number by the SETUP mode “MIDI device ID
setting.”
When the sequence software transmits by “7F,” it means
“ALL DEVICE” and therefore, it need not be setup.
Refer to page “131”, SETUP mode “MIDI device ID setting”
for operating procedure and details.
Press the [TIME BASE SEL] key, and then change the
time base display to MTC.
<Notes on MTC related setups>
By “
MTC offset time setting
” and “
MTC offset mode setting
,”
at what position (ABS 0 or 001BAR/1BEAT/00CLK)
should the setup MTC (MTC offset time) is to be output
is set. When setting the start time of the tune in the
sequence software by these setups, be careful of the
following points.
• Offset mode: For ABS
If playback is started from ABS 0, since MTC will be
output starting from the MTC offset time that has been
set, the start time of the tune set by the sequence software
must be set about 3 seconds later from the MTC offset
time that was setup. This will provide time because the
sequence software cannot sync immediately after MTC
is output. For example, if the initial setting of “
00h 59m
57s 00f 00sf
” is used, set the start time of the tune to “
01h
00m 00s 00f
.”
If playback is thus started from ABS 0 (LOCATE ABS 0),
sync will be obtained by the time it reaches the first bar
and therefore it can be made to sync from the head of
the tune.
• Offset mode: For BAR
As mentioned before, because the “
ABS 0
” position is set
at the “
002BAR / 1BEAT / 00CLK
” position, the setup MTC
offset time can be set to the head of the tune without
taking into account the time until reaching sync, as
mentioned above. The length of the time two bars
beforehand will change in accordance to the first bar
setting for “
signature
” and “
tempo
.” For example, it will
be long if the tempo is set slow. This mode can be
effectively applied when using the MIDI clock and MTC
in parallel, and when using MTC for the sync signal while
controlling the recorder with time base BAR/BEAT/CLK.
Confirming MTC sync/MMC
During recording and at playback after recording, time
base MTC is displayed according to the setting and MTC
is output at the same time.
Check that the VF80 traveling position (MTC) and the
traveling position of the sequence software in sync are
matched.
Send MMC commands such as PLAY, STOP and
LOCATE from the sequence software to see that the
VF80 will be properly controlled.
When a correct MIDI command (MMC or FEX) is received,
“MIDI” in the display will be lit for about 40msec.
There is no setting in the VF80 to receive MMC but it
will operate if a correct MIDI signal is input.
If sync and control cannot be done correctly, re-check
connections/cables and the setting of both equipment.
Execution of recording
Carry out various recordings while synchronizing the
VF80 and a MIDI sequencer with the MIDI clock.
