Setup of D-108
1.Set to same frame rate as the sequence software by the SETUP mode "MTC Frame rate setting."
# Refer to page "113", SETUP mode "MTC Frame rate setting" for operating procedure and details.
2.Set to the desired mode by the SETUP mode "MTC offset mode setting."
# Refer to page "114", SETUP mode "MTC offset mode setting" for operating procedure and details.
3.A random offset time can be set by the SETUP mode "MTC offset time setting."
# Refer to page "113", 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 "115", SETUP mode " Slave mode setting" , and page "116", SETUP mode "Slave mode type setting", for
operating procedure and details.
5.Press the DISP SEL key while pressing on the EXECUTE/YES 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 D-108 cannot immediately
chase lock after input of MTC, in order to sync the D-108 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 D-108 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 "0002BAR/1BEAT/00CLK" position in the D-108, 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 IN LED of the D-108 will light, "CHASE" 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 D-108 are the same.
2.When the sequence software stops, MTC will be interrupted and the D-108 will also stop.
"CHASE" in the display will change from lit to blinking.
3.During FF/REW of the sequence software, D-108 will remain stopped but upon starting to record, the D-108 will
immediately chase lock.
* Should it not be possible to chase lock, re-check connections / cables and all settings.
Execution of recording
Carry out various recordings while the D-108 is chase locked to the sequence software.
<Note>
Chase lock of the D-108 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 D-108 learn the master speed by entering PLAY prior to
recording. By doing so, it will be lock faster from the second and later sessions.
