Roland VS-1680 - Manual (Page 8)

When synchronizing using a MIDI
sequencer as the master, the VS-1680
does not respond to the sequencer
messages
●The MIDI cable is not connected correctly.
●The MIDI cable is broken.
●You are trying to synchronize using the MIDI clock.
→The VS-1680 cannot be run in slave mode using a
method other than MTC.
●The EXT indicator is off (“Sync Source” is set to
“INT”).
●The two devices are not set to the same type of MTC
(during MTC synchronization).
●The settings of the MIDI sequencer are not correct.
●The MIDI sequencer is not in playback standby
mode (with the PLAY indicator blinking).
●MTC reception is in poor condition.
→Setting the Sync Error Level to “5” or higher may
improve conditions.
With a video device as the master, the
VS-1680 does not respond
●The cable connected to the L-connector or the MIDI
cable is not properly connected.
●The MIDI cable is broken.
●The EXT indicator is off (“Sync Source” is set to
“INT”).
●“SysEX.Rx.” (System Exclusive Receive Switch) is
not set to “On.”
●“MMC” (MMC mode) is not set to “SLAVE.”
The MTC frame rate of the video device differs from
that of the SI-80S (Roland Video MIDI Sync
Interface), or the video and the VS-1680 are not set to
the same type of MTC.
●MTC reception is in poor condition.
→Setting the Sync Error Level to “5” or higher may
improve conditions.
Other problems
Data on the disk drive was not saved
properly
The VS-1680’s power was turned off without perform-
ing the shutdown process.
●The power was turned off while the disk drive was
operating.
●A strong shock was applied to the disk drive.
●The disk drive or SCSI cable was connected or dis-
connected while the power was still turned on.
→Reinitialize the disk drive (and also execute physical
formatting) (Owner’s Manual p. 111). Also, we rec-
ommend that you execute Surface Scan as well
(Owner’s Manual p. 113).
