(Trial
2:
Tempo
and
Pitch)
As stated
previously
in "Trial
1
"
we
used
the
sample
in
bank
8
from
"ALLS"
file. The
other
banks
1
~7
are set
with
the
same
program
number
to use
them
as a
single
program,
and
individual
key
ranges
to
play
each
sample
with the
corresponding
key.

Other
parameter
settings
for
banks
1-7:
PROG.
NO.;
1,
MID!
CHANNEL;
ON,
CONSTANT
PITCH;
ON.
Each
bank
will receive
data
on
all
MIDI
channels
1-16 (OMNI
ON) so
that it is
not
required
to
set
your
MIDI
keyboard's
channel.
With the
above
settings,
you
can use
them,
for example,
by
freely
playing
samples
of
banks
3-7
during
repeated play
of a sample
of the
bank
1 or
2.
First try
playing
back
each
individual
sample.
a)
Constant
Pitch
In this
program
all the
banks
1-7
have
been
set
to the
CONSTANT
PITCH:
ON.
As
explained
before,
when
this
parameter
has
been set to
ON,
the
sample
will
be
reproduced
at a
fixed
pitch
whatever
MIDI note
number
the
bank
receives.
If
you
wish
the
sample
reproduced
at
the
original
pitch by
triggering
any
key on
the
keyboard,
you
can do
it by
setting
that
parameter
to
ON and
not
setting
the
key range
or
transposition,
etc.
Try
cancelling
the
constant
pitch
of a
sample
in any
bank
of 1
~7
.
If
you
play
the
same
key
,
you
can
play
the
sample
at
different
pitches.
One
more
thing to
remember is
that
with the
CONSTANT
PITCH
set
to
ON the
original
pitch
can
be
changed
with the
TRANSPOSE
and
SAMPLE
TUNE.
This
modified
pitch is
reproduced
when
the
bank
key
is
pressed.
b)
A
Phras©
Loop
with a
Specific
Tempo
The
sample
in
bank 1
has made
of
one-bar
rhythm
pattern at
the
tempo
of
1
20 (
1
20
beats
per
minute)
and
looped
with the
LOOP/ONE
SHOT
ON.
In
making
this kind
of loop,
first
you
must
make
sure
to
adjust
the
length
precisely.
If
this
is not
done,
it is
impossible
to
maintain a
constant
tempo.
For those
cases,
this
manual
provides
"Tempo-to-
Sample
Point
Conversion
Table"
on page
54,
55.
When
making a
loop
at a tempo
of
120,
first
refer to
the
table
and
find
the
tempo
of
120,
then the
corresponding
sample
point
(=bar
length):
64,000.
This
value
is
for
the
loop
point.
Also, a
calculation
by
adding the
start
point value
to
the
sample
point
value (64,000)
should
be
set as
the
end
point
value.
In
other words,
the
sample
from
start to
end
will be
exactly
64,000.
Through these
operations,
you can
make a
loop
at the
tempo
of
120.
c)
Matching
Different
Tempos
of
Samples
When
playing
together
several
samples
with
individually
specific
tempos,
it is
advisable
to
use
"Tempo-
to-TRANSPOSE/SAMPLE
TUNE
Conversion
Table"
provided
on
page 56,
57.
For
example, the
sample in
bank
2 is made
of
one-bar
rhythm
pattern
at a
tempo
of
130.
If
you
wish it
played
at a
tempo
of 1
20,
first
refer to
that
table and
find
the
tempo
of 1
30
across
the
center.
Then
down
the
offset
value listed
in the
left most
column
, find
"--10"
(because
the
required
tempo 120
is
calculated
adding
offset
value
to
original
tempo:
(130-10=120)
"-1/-39").
These
two
values
should be
respectively
assigned to
the
TRANSPOSE
and
TUNE
parameters.
That
is,
the
sample
in
bank
2
can be
reprodr-ed
at the
tempo
of
120,
if
the
TRANSPOSE
is set
to
-1
,
and
the
TUNE
set
to
-39.
*
After the
sample
is
set
at
another
tempo
in
this
way,
of course
since
the
pitch
has
been
altered,
there
will be a
small
difference
in
the
tuning
from
the
original
one.
