Sequential prophet 5 - Release Footswitch; Retuning; Voice Assignment; Voice Defeat

1-5 RELEASE
FCXJTSWITCH
In
PRESET
Mode,
if the
RELEASE
switch
is
programmed to
be off, but the
program
also
contains
an
amplifier
envelope
release setting
which can
have an audible
effect,
this
release
can
be
engaged
either
by switching
RELEASE
on,
or by using
the
included
footswitch
(which
connects
to the
RELEASE
FOOTSWITCH jack on the back
panel).
The
footswitch
will
function
like the
RELEASE
switch on the front panel, except
it
only
operates
when
the
RELEASE
switch is
(programmed) off.
The footswitch
then
takes
the
place
of
the
RELEASE switch.
When
pushed, the
programmed
amplifier
release
cycle
is
enabled.
When not pushed,
the
amplifier release cycle is
set
to
minimum.
In this
respect, the
footswitch
functions
similarly to a piano's sustain
pedal.
Further
expressive
influences on the
Prophet's
programs can be
brought
about
through
the use
of
other accessories
which connect
to the
Prophet's back
paneL For
information
on these
possibilities, see
Section
3.

RETUNING
Although the
microcomputer tunes the
oscillators when the
Prophet is first turned
on,
it will
occasionally
be necessary to retune,
particularly
during the first few minutes
of
operation
since the oscillators
need time to
stabilize. (After
20 minutes
or so the
instrument should
not have to be
retuned very often, unless there is a radical
temperature
change in the
room.)
Hitting the
TUNE switch will
tell the computer
to retune
the
oscillators.
During this
process
the control panel goes
dark—except for the TUNE switch—for two
to eight
seconds
(depending on how far out of
tune the
oscillators
were), then
will return
to the
previous front panel
status.
1-7
VOICE ASSIGNMENT
The microcomputer assigns
the five
synthesizer voices
to
keys played
on the
keyboard.
If the same key is
struck
repeatedly, the microcomputer assigns the
same voice. If
more than five keys
are held down at
the same time, the computer will
reassign the
earliest used voices first.
For example:
playing
C, D, E,
F, G, and A
in succession
and
holding all six keys down
will cause D, E,
F, G,
and
A to be
sustained—the
C
will
disappear when
the
A is
played. In other words, the
Prophet
normally operates on
a
"last-note priority" system: each
new note played is
assigned
to the earliest-used
voice.
There is an
exception to this
system. If the UNISON switch is on, all five voices
are
assigned
to a single key. In
keeping with conventions
established
by monophonic
synthesizers, UNISON assigns priority to the lowest
key
held.
1-8
VOICE
DEFEAT
For
the occasion
when
a
voice
may
become unplayable
due to component failure, a
Voice
Defeat allows you to delete the failed voice from the assignment system. The
Prophet can
then be
played normally,
with the remaining voices.
