4.2 Editing a program
This
section explains the procedure
for
editing a program.
*
In
these explanations
WI~
are modifying parameter values using only the knobs, but
for
making
fine
changes
it
is
more efficient
to
use the
VALUE
keys.
•Initializing a
program
The
programs of the Prophecy consist of a complex combination of settings. In order
to
help you
understand the
procedure
for
creating a program,
we
will initialize a program
to
the simplest possible
settings
as
follows.
III
Press
the
PERFORMANCE/EDIT
Select
key
to
enter
Edit
mode
(the
lower
LED will
blink).
[gJ
Press
the
COMMON
key to
enter
the
Common
section. Use
the
PAGE
keys
to
move
to
page
CMN-10 [Initialize Program].
~
Press
the
ENTER key. You will
be
asked
<Are
you
sure?>
Press
the
ENTER
key
once
again. The
program
will
be
initialized,
and
the
display
will indicate <COMPLETED>.
Now play the keyboard.
You
will hear a simply sawtooth wave.
• Oscillator
settings
The
oscillator
is
the section that creates the "waveform", which
is
the most basic element
of
the sound.
The
Prophecy
is
able
to
produce a wide variety
of
waveforms, but
in
this example
we
will use the most
basic
Std.OSC
in the following explanation
of
the sound-editing procedure.
III
Press
the
OSC
key
to
enter
the OSC section. Use
the
PAGE
keys
to
move
to
page
OSC-
cmn1 [Oscillator Set].
Make sure that the display indicates "SETOl:Std.OSC+Std.OSC". This means that Std.OSC is
assigned
to
both OSCl and
OSC2.
[gJ
Use
the
PAGE
keys
to
move
to
page
OSC-cmn7 [OSC
Menu].
Move
the
knob
located
below
the
[STD1]
display
so
that
it
reads
[STD1] ,
and
press
the ENTER key. You will
move
to
page
OSC:L-1
[Basic Pitch].
The four parameters shown in this page specify the pitch of OSCl.
As
you play the keyboard,
modify the
parameters and notice how the pitch changes.
~
Use the PAGE keys to
move
to
page
OSC1-5 [STD WaveLevel]. Use knob
1located
below
the
"SAW"
display,
and
change
it
to
"PULSE".
Play
the
keyboard
and
notice
that
the
waveform
has
been
changed
from
sawtooth
to
pulse.
@J
Use
the
PAGE
keys
to
move
to
page
OSCl-6
[STD
Wave
Form].
While
playing
the
keyboard,
rotate
knob
3located
at
the
lower
right
of
the
"LF02:Int+00" display. Notice
that
the
sound
begins to
"waver".
This is because
LF02
is
being
used
to
vary
the
width
of
the
pulse
wave.
For this example, set it to "Int+SO".
(§I
Now
we
will
modify
the
setting
of
the
LF02
that
we
heard
in
step
I!J
.
Press
the
LFO
key
to
move
to
page
LF0-1 [LFO Menu]. Rotate knob
2located
under
the
[LF02] display,
so
that
it
reads
[LF02]
,
and
press
the
ENTER key. Next
use
the PAGE keys to
move
to
page
LF02-2
[Frequency]. Rotate
knob
1
located
under
the
"005(0.150[Hz])"
display.
Notice
that
the
frequency
of
the
"wavering"
changes.
For
this
example,
set
it
to
"031(0.800[Hz])".
