Fostex VR800 - Manual (Page 72)

VR800 Owner’s Manual (MIDI Synchronization)
72
* Initial setting: 00
* Permissible setup ID: 00 ~ 99
* This item will be the setting common to all programs.
* This setting cannot be saved/loaded as song data.
* This setting will be held even though power is switched OFF.
# Refer to page "104", SETUP mode "MIDI device ID setting" for operating procedure and details.
6.Press the TIME BASE SEL key to show time base in the MTC display.
Confirming MTC sync/MMC
1.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 VR800 traveling position (MTC) and the traveling position of the sequence software in sync are matched.
2.Send MMC commands such as PLAY, STOP and LOCATE from the sequence software to see that the VR800 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 VR800 to receive MMC or FEX 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 a VR800 and a MIDI sequencer with the MIDI clock.
<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/BEAT
As mentioned before, because the "ABS 0" position is set at the "-002BAR / 1BEAT / 00CLK" (default value) 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 VR800 with time base BAR/BEAT/CLK.
