VR800 Owner’s Manual (MIDI Synchronization)

3.A random offset time can be set by the SETUP mode "MTC offset time setting."

# Refer to page "96", SETUP mode "MTC offset time setting" for operating procedure and details.

4.Set slave mode to "On" by the SETUP mode "Slave mode setting," and the slave type to "Vari" by the SETUP mode "Slave mode type setting."

#Refer to page "98", SETUP mode " Slave mode setting" , and page "99", SETUP mode "Slave mode type setting", for operating procedure and details.

5.Press the TIME BASE SEL key to change the time base display to MTC.

<Precautions at MTC related setups>

The position (ABS 0 or 001BAR/1BEAT/00CLK) when the setup MTC (MTC offset time) should be output was setup by the "MTC offset time setting" and "MTC offset mode setting." In accordance to start time of the tune set by the sequence software, setup as explained below.

Offset mode: For ABS

Set the MTC offset time about three seconds prior to the start time of the tune set by the sequence software. Because the VR800 cannot immediately chase lock after input of MTC, in order to sync the VR800 from head of the tune, set the preroll using the sequence software, and playback from before the actual head of the tune to allow the VR800 to enter into sync by the time it arrives at the head of the tune.

Offset mode: For BAR/BEAT

The MTC offset time can be set to the same time as the start time of the tune set by the sequence software. Because the "ABS 0" position is set at the "-002BAR/1BEAT/00CLK" (default value) position in the VR800, as mentioned before, the preceding time required for sync is already set. The preceding time of two bar lengths could change in length depending on the first bar's "signature setting" and "tempo setting" mentioned before. For example, it will be longer if the tempo is slowed down.

Confirming chase lock

1.When the sequence software is played, “MTC” of the VR800 will light, “SLAVE” in the display will change from blinking to lit and the chase lock will be completed.

Check that the MTC output by the sequence software and MTC time displayed in the VR800 are the same.

2.When the sequence software stops, MTC will be interrupted and the VR800 will also stop.

"SLAVE" in the display will change from lit to blinking.

3.During FF/REW of the sequence software, VR800 will remain stopped but upon starting to record, the VR800 will immediately chase lock.

<Note>

Chase lock of the VR800 by MTC only is permissible when speed difference of the MTC from the master is within +/- 5.6%. Against the MTC within this range, variable pitch will be constantly applied internally for chasing. Chase lock, however, will not function against MTC at a speed difference outside this range. Also, when the master speed difference is large, it is advised to let VR800 learn the master speed by entering PLAY prior to recording. By doing so, it will be lock faster from the second and later sessions.

* Should it not be possible to chase lock, re-check connections / cables and all settings.

Execution of recording

Carry out various recordings while the VR800 is chase locked to the sequence software.

<One Point Advice>

Sync signal "Free" of the "Slave mode setting" menu:

When the VR800 is made to chase lock by MTC only, variable pitch will be constantly applied by external MTC. If a digital signal is output to an external digital equipment from the VR800, it will not be able to follow the speed difference (MTC speed difference of the master) of the VR800 and the external digital equipment, in some cases, may not be able to input a continuous digital signal.

As a counter measure, the sync signal should be set to "Free" by the "Slave mode setting" menu. Using this setting, the VR800 will enter self operation by the internal clock, after completion of chase lock, and it will be possible to supply a stable digital signal to the external equipment.

Under this setting, when MTC drift between the master unit and slave unit exceeds 10 frames, the VR800 will assume that chase lock has been disengaged and the slave unit will carry out position matching again with the master unit (re-chase operation). During the re-chase operation, sound output will be muted and the digital signal will also be interrupted. If it is within 10 frames, the slave unit will continue to run while admitting this drift.
