Sequential prophet 5 - Chapter 1: Getting Started

INTRODUCTION
This
section
explains
the
modes
of
operation
and
functions of
the
controls comprising
the
"modules"
(for
example,
OSCILLATOR,
FILTER,
AMPLIFIER,
and LFO) outlined
on
the
front
panel.
The
alternatives
of
each
switch
and
ranges
of each
knob
are
described
relative
to
the
overall
signal
flow
of
the
voices
and to the
modulation
circuitry.
Section
1
introduced
basic
PRESET
operation
with the
factory
programs accessible
through
the
PROGRAMMER.
It
is
true
that
the
Prophet
can
be
used
exclusively in
PRESET
Mode,
in
which
case
the
voice
and
modulation
controls
would not
be used very
often.
However,
using
the
instrument
solely
in
this
way
defeats
a
large part
of its
overall
purpose,
which
is to
allow
keyboard
synthesists
to
create
and record
sounds
appropriate
to
their
own
music.
The
creation
of
satisfying
custom
programs depends
entirely
on
familiarity
with
the
controls
described
below.
By the
way,
in
describing
the
front
panel,
this
section
will
not
attempt
to
comprehen-
sively
explain
synthesis
technique.
However,
by
referring to
the
patch
diagrams in
Section
8
while
playing
through
the
factory
programs,
you
will soon
grasp some
of the
sonic
possibilities
the
Prophet
makes
available.
To gain
familiarity
with the voice
and
modulation
controls,
we
encourage
you to
edit the
factory
programs.
Programs
5-7
and
5-8
(in
File
1)
are
specifically
included for
editing
practice—please
see the
notes
accompanying
these
programs
in
Section
8.
For
more
information
on
synthesis
technique,
refer to the
books
and
magazines listed
in
Section
7.

MODES OF
OPERATION
The
Edit
feature
of
PRESET
Mode
is a
powerful
tool that
allows
you
to
experiment
with
program
changes
by
selectively
adjusting
the
front
panel
controls.
The
original
program
remains
unchanged
and
can
be
restored
at any
time by
simply
hitting its
PROGRAM
SELECT
again.
In
addition to
PRESET,
the
Prophet
has
MANUAL
and
RECORD
Modes of
operation.
In
MANUAL
Mode a
patch
can
be
formed
entirely
"from scratch."
RECORD
is a
momentary
mode
for
storing
or
relocating
programs.
A
"patch"
becomes a
"program"
when
recorded.
Custom
programs
can
therefore
be
created
in two
ways:
1)
by
recording
manually-formed
patches
or 2)
recording
edited
programs.
Edited
programs
can be
recorded
into
the original
location
if
the original
program is
not desired,
or
in a
new
location.
The front panel
controls are
color-coded
to
clarify the
modes
of
operation
and
the
function of the
computer's
memory.
All
black knobs
and
switches
are
programmable:
that is, their
settings can
be
recorded
into
memory
and
recalled
in
PRESET
Mode.
