MIDI Synchronization
In this chapter,
we
explain
how
to
synchronize a
MIDI
sequencer
to
the
DR4vr.
The DR4vr
is
used
as
MIDI
Clock master,
and
the
MIDI
sequencer
is
used
as a
MIDI
Clock
slave.
The DR4vr
cannot be used
as a
MIDI
Clock
slave.
!B-n3M
MIDI Interface
Card
To
use
MIDI
synchronization,
you must
install
an
optional
IB-113M-V3.0 MIDI
Interface
card.
Please contact
your Akai
professional dealer for
details.
Installing
an optional IB-
1 1
3M-V3.0
on
the
DR4vr
will
allow
the
DR4vr
to function as a ci(x:k
master
to
synchronize
the external
MIDI
devices such
as
a sequencer.
You
can
also use the
MMC
&MTC
software
to control the
DR4vr
externally.
If
you
are using multiple
DR4vrs
or
DR4ds
for
synchronization, be
sure to
install
the
IB-1
1
3M-V3.0
on
the
master device (ID=1).
Installing
this
card
on
slave
units will
cause
improper
operation.

Operation
When
playback
is
started
and stopped on
the
DR4vr,
MIDI
Start
and Stop messages
respectively
will
be
sent to
the sequencer,
and
it
too will
start
and
stop playback.
The
sequencer
will
be synchronized
to the
MIDI
Timing Clock
data
being output by
the
DR4vr. These
types
of
MIDI
messages
are called
System Real-Time
messages.
MIDI
Sync Notes
•
The MIDI
sequencer
is
always synchronized according
to the
time displayed on
the
DR4vr.
And,
the
tempo
map
and
beat
map
always use 0001-01-00
as their
initial start point.
This
applies
to
both absolute
and
relative time.
Therefore,
MIDI
synchronization
can be
offset
by
using
the
DR4vr's
relative
time
function.
