The MID!
Timing Clock
data output
by
the
DR4vr
will control the
tempo
of the sequencer.
Therefore,
you must
first
create
a
tempo
map
on
the
DR4vr.
so
that the
sequencer
plays
at the
correct
tempo.
You
can
set
up
to
three
tempo
maps.
If
a
song's
tempo
remains
the
same
throughout, the
tempo
map
will
have
only one
entry.
That
entry
will
be
at
the
beginning of
the
song and
will specify the song's tempo.
If
the song contains any
tempo
changes, these
changes
will
have
to
be
entered into the
tempo map.
Initially,
the
first
entry
in
the
tempo
map
i.s
.set
to
1
20 bpm.
Tempo map
entries are
displayed
in
the
following format: 00
I-
1200 This
means
that the
tempo
setting
is
120.0
bpm
starting
at
entry
001
(initial setting).
When
the next entry
is
added
to the
tempo map.
it
will
be
displayed as
OOd-
1500
.
In
this
case
the
tempo
has been changed
to 150.0
at
entry 002.
Before
creating a
tempo
or beat
map,
it
's
a
good
idea
to jot
them
down
on paper
first.
This
way
you'll also
have
a
hard
copy
for
quick
reference.
The
following
tables
show
how
you
could
layout
a beat
map
and tempo map.

As
well
as setting the
tempo, you must
also specify the song's beat (time
signature). Just like
tempo,
if
a
song's beat remains
the
same
throughout,
you
only
have
to specify
it
once
at
the
beginning of
the song.
However,
if
the beat
of
the
song
changes,
these
changes
will
have
to
be
entered
into the beat
map.
Initially,
the
first
entry in the beat
map
is
set to 4/4.
Beat
map
entries are
displayed
in the following format:
0 l-OH-0^
This
means
that
the beat
setting
is
4/4
starting
at
entry 01
(initial entry).
When
the next entry
is
added
to the beat
map,
it
will
be
displayed
as
08-03-OH
.
In this
case the beat has been changed
to 3/4
at
entry 02.
