Delete; Quantize - Yamaha qx21 Owner's Manual

If
ON
is
selected,
press the
RESET
button
to clear the
LED
display
and begin op-
eration as a
MIDI
status
monitor.
Job
C-6 must be
recalled
and
set to
OFF
to
resume
normal
QX21
operation.
If
OFF
is
selected, pressing
RESET
returns to job
A-1
Save Temporary
Buffer
(Job D-1)
As
we
discovered
in
the
Quantize
section,
above, the
QX21
has
a
temporary
buffer
memory.
Executing
this
job
swaps
the contents
of
TRACK
1
and
the
temporary
buffer, recalling the
temporary
buffer data
into
TRACK
1,
and saving the
TRACK
1
data
in
the temporary
buffer.
In
addition to allowing
you
to recall
the
original
data
after a
quantize
operation, the
temporary
buffer
is
also useful
in
a
number
of
editing
situations.
Suppose,
for
example,
that
you have
a phrase
which
will
occur
more
than once during the course
of
a
composition. This phrase can be
created
and
saved
in
the temporary
buffer
using the
SAVE
TEMPORARY
BUFFER
job.
It
can then be
recalled
and chained onto
or inserted
into
the data
on
TRACK
2
as
needed.
Call
job D-1 by holding the
RESET
button
and
pressing the
JOB/STEP
SIZE
B/D
selector
once.
The LED
display
will
read
[bfcj
and
the
TRACK
1
indicator
will flash.
Pressing the
START
button then
actually
executes the
SAVE
TEMPO-
RARY BUFFER
job, or
RESET
to cancel.
Delete
Channel
(Job D-2)
Quantize (Job
D-3)
This job
makes
it
possible
to delete a single
MIDI
channel from
a
multi-channels
recording
(refer to
"SEQUENCING MULTIPLE TONE GENERATORS"
section).
Since
material
recorded
on
other
MIDI
channels
is
left intact, this
function eliminates
the
need
to
redo an
entire
recording
if
only
one
channel
is
not
satisfactory.
Call
job
D-2
by holding the
RESET
button
and
pressing the
JOB/STEP
SIZE
B/D
selector twice.
The
LED
display
will
read
\Jc]
.
Then
use
the
-1 and +1
buttons
to select the
number
of the
MIDI
channel
to
be
deleted
(1
-
16). Finally, press
the
START
button
to
delete the selected channel.
With
this
job
it
is
possible to correct "off-time" notes entered
in
the
real
time record
mode
by
forcing
all
notes
to
fall
on
the nearest "quantize"
unit.
The
available
quantize
values
are:
1
/4,
1
/6,
1
/8,
1/12,
1/16 and
1
/24
notes.
For example,
if
a phrase
in
which
the smallest note length
is
1
/8 notes has
been
entered
in
the
real
time record
mode, and
some
of
the notes
are a
little
off-time—
i.e.
the notes
do
not
fall
precisely
on
1/8th
measure increments—
the phrase
can be
quantized
to
1/8 causing
all
the notes
to
fall
into
perfect time.
The
QUANTIZE
job can be used only on
data
which
is
on
TRACK
1
.
First
call
job^
D-3 by
holding the
RESET
button
and
pressing the
JOB/STEP
SIZE
B/D
selector
3
times.
The
LED
display
will alternately
read
[9t]
indicating that the
QUANTIZE
job
is
active,
and
the
currently selected value.
Use
the
-1 and +1
buttons
to select
the desired value. Pressing the
START
button then
actually
executes
the
QUANTIZE
job, or
RESET
to
cancel.
The
quantized data
is
left
on
TRACK
1
.
To
give
you
a
second
chance
just
in
case quantizing
ruins
your
recording, the data
is
stored
in
the
QX21
's
temporary
buffer
memory
prior to
quantizing.
The
data
in
the temporary
buffer
can
be
recalled to
TRACK
1
using the
SAVE
TEMPORARY
BUFFER
job
(job
D-1)
described above.
NOTE:-
The
selected quantize value
must be
equal to or smaller than the smallest note
length contained
in
the data
to
be quantized, otherwise
random
omission
of
notes
or
changes
in
note
length
may
occur (thus the
temporary
buffer
save
operation!).
