MIDI
Synchronization
•
MIDI
sequencers always
treat
songs
as separate
entities,
and
usually
start
song playback from
the
first
beat
of
the
first
bar.
However,
the
DR4vr
treats
individual songs (recorded on
the
same
disk) as
one
continuous
recording. Consequently, subsequent songs do
not
start at
the
tirst
beat
of the
first
bar. In this case,
you
inustuse
relative
time and
set
an
offset to
make
the
beginning
of subsequent songs coincide with
the
first
beat of the
first
bar on
the sequencer.
•
When
controlling a
MIDI
sequencer with
MIDI
sync,
setting
a negative
offset will disable
sequencer playback.
As
an
alternative, insert a
blank bar
at
the
top of the sequencer
song. This
will
produce
the
same
result as setting a negative
offset
on
the
rjR4vr.
• If the
IB-113M
MIDI
Interface card has not been
installed,
and you
select
MIDI
sync, then
press the
STORE/ENT
key, the
message noOPk
lOn
will appear.
MIDI
Timecode
Synchronization
Pressing
the
PLAY
key
(or
REC
and
PLAY
keys)
on
the
DR4vr
will output a
MIDI
timecode
signal corresponding
to the specified
SMPTE/EBU
timecode
type
from
the
MIDI
OUT
terminal during playback
(or recording).
MIDI
Clock
Synchronization
Pressing the
PLAY
key
(or
REC
and
PLAY
keys) on
the
DR4vr
will
output a
MIDI
clock
signal
corresponding
to the
programmed
Tempo Map
from
the
MIDI
OUT
terminal during playback
(or recording).
Although
the Cue/Review,
«PLAY»,
REPEAT,
PLAY TO
OUT, JOG/SHUTTLE,
and
VARI
functions of
the
DR4vr
work
during sync
operation, the
MIDI
timecode and
MIDI
clock
commands
are not issued.
Therefore, the connected
external devices are stopped during those
operations.
It
should be noted
that
operating
the
PLAY
and
STOP
keys
(PLAY-> STOP-> PLAY)
very
quickly (within
one
second) on
the
DR4vr
during the
MIDI
clock synchronization
may
cause
the
playback sound from an
externa!
MIDI
device
to
slip.
About
MMC
(MIDI
Machine
Control)
MIDI
Exclusive
Command
and
MIDI
Machine
Control of
the
DR4vr
conform
to the
MIDI
Machine
Control
RP
(Recommended
Practice) Version
1.
00. This allows you
to
control the
DR4vr
with
the
MMC
protocol
by
connecting
the external controller
and
the
DR4vr
using
the
MIDI
interface
board (IB-1I3M-V3.0).
•
Setting a device
ID number
only
on
the
DR4vr
will
allow
the use of
MMC.
No
mode
settings
are required.
MMC
commands
can be
sent to the
DR4vr
at
anytime.
Match
the
MIDI
device
ID
setting to that
of
the external
controller. If
the external controller
does
not
have an ID
setting,
any
ID number on
the
DR4vr
can be
set.
