Keyboard magazine (20605
Lazaneo, Cupertino, CA 9501*) carries many articles on
popular synthesis. And there is Polyphony magazine (Box 20305, Oklahoma City,
OK
73156) which concentrates
on more technical
aspects. Also,
check
into
synthesis
lessons, seminars,
or courses which are increasingly being
offered
by colleges and
individuals.
Be
advised
that in the excitement of creation, new, interesting
patches tend to escape
if
not documented. Panel
blanks are provided for this purpose in
Section 12. If a
program is not documented when
created, the programmed control settings may only
be
discoverable
by rotating all knobs, in
Edit Mode, as
explained below.)

EDIT MODE
Programmable controls
(such as GLIDE and OSC A FREQUENCY)
are subject to
setting by the computer, while non-programmable
controls (such as the two wheels)
are not controlled by the computer. Generally, the programmable
controls are crucial
to establishing the characteristic
sound of a program, while the non-programmable
controls are
for
performance
and mode control. However, this
does not mean that the
programmable controls are unalterable. To
the contrary, the programmable controls
can be altered at any time and each alteration
will influence the sound. Adjusting the
programmable controls
is called editing.
Edit Mode is a powerful
tool that allows you to experiment with program changes
by
selectively
adjusting each front pane! control.
The original program remains unchanged
and can be restored
at any time. Edited programs can
be recorded into the original
location if the original
program is not desired, or
into a program location
which
contains
an undesired program.
In Preset Mode as you
select different programs there
is no way for the knobs and
switches to move
themselves (as they would have
to) to indicate
their
programmed
settings. The controls just stay where
they happen to have
last been set. Edit Mode is
entered when
the Prophet-600 is in Preset
Mode and a programmable switch
is toggled,
or a programmable knob
is rotated. When this occurs
the decimal point between the
PROGRAM digits
lights to indicate Edit
Mode. The switch or knob
then becomes
active, physically indicating
its current setting. The
programmable parameters
of
inactive,
unmoved switches
or knobs do not change. So,
unmoved switches and knobs
do
not necessarily
show their currently-programmed
settings. Therefore,
to
discover
the
programmed setting
of a knob or switch, you have
to rotate or toggle it, while
repeatedly checking the
edition
against
the original program.
As an example
of editing, suppose you like
program 15 but want to
change OSC A
waveforms and prefer
a brighter tone:
1. Check that PRESET
is on.
2. Select program 15.
3. Switch waveforms
as desired.
U. Raise FILTER CUTOFF for desired brightness.
5. You can cancel any changes and
return to the original program
by
again
pressing
PROGAM SELECTS 1 and 5.
