For instant access at the touch of a button, you can store
up to five selected voices in the Digital Synthesizer Memory
BANKS 1 thru 5 (12a).
Operation
1. Select the voice you want to store.
2. Hold down the red STORE button (12b) and simultaneously
press the desired BANK button (12a), for example BANK
1. The VOICE/STYLE display will indicate “b.1”. The
selected voice is now stored in BANK 1 and can be recalled
any time by pressing that button.
Stored voices are retained in their banks even when
POWER is turned off.
Saving voice data to a bank deletes any previous settings
already stored there.
EFFECTS
Overview
The PSS-680 offers six different kinds of effects, described
below, which can be added to the FM instrument voices for
even greater tonal variation. They do not affect the PCM
percussion sounds.
Operation
1. To obtain the effect you want, simply press the corre-
sponding button in the EFFECT group.
The little red indicator next to it will light up, showing
that an effect has been selected. You can use several or
all effects at the same time.
Points to Remember
DUET and PORTAMENTO depend on other settings
as well — see below for details.
Some preset voices are already programmed with effects
— for instance, VIOLIN 1 (10) and STRINGS (41) use
vibrato, HARP (37) sustain, and so on. In such cases,
the corresponding EFFECT indicator will light up
whenever that instrument is selected. For these in-
struments, you can of course turn OFF that effect by
pressing its selector.
With the exception of STEREO CHORUS, all effects
influence only the notes you are playing in the MEL-
ODY SECTION (21) of the keyboard.
Effects can be stored independently for each SONG
MEMORY MELODY bank (see p.22.). During bank
playback, these individual effect settings are used au-
tomatically and cannot be canceled with the EFFECT
selectors.
Try out all six effects to understand how they work and how
they influence each instrument sound differently. Here is a
short explanation of what each effect does, and how to adjust
PORTAMENTO:
VIBRATO
Vibrato regularly (cyclically) raises and lowers the pitch of
a sound. It occurs naturally in the human voice, and many
acoustic instruments, for example strings, make use of it.
Usually, this effect does not start right away when a note is
sung or played, but after a certain delay time.
The PSS-680 VIBRATO also simulates this natural delay.
For an even more realistic effect, each voice has the vibrato
delay that suits it best.
SUSTAIN
Sustain lengthens the release rate of a voice, causing the sound
to linger even after the keys have been released. It works
rather like the damper pedal of a piano. The sustain effect
is also different (longer or shorter) for each voice.
REVERB
Reverb, short for reverberation, gives a spacious effect similar
to an instrument being played in a large hall. It can add at-
mosphere to almost any voice. Try it with SMALL CHURCH
ORGAN (29) or HUMAN VOICES/CHORUS (94 to 96).
PORTAMENTO
Range: 1 to 5
Portamento is the smooth pitch glide effect that occurs be-
tween notes played consecutively on some instruments, such
as the violin and trombone, or sung by the human voice. The
speed with which the pitch changes between the keys you
play can be adjusted over a 5-step range (values from 1 =
slow to 5 = fast). Fast settings provide a less extreme effect
which can make string instrument voices etc., sound very
realistic.
Operation
1. Hold down the PORTAMENTO button.
The TEMPO/PARAMETER & VALUE display will now
show the current portamento speed setting. To change this
value,
2. keep holding down the PORTAMENTO button and use
the VALUE buttons.
Pressing + increases portamento speed, SHORTENING
the portamento time for a LESS pronounced effect. –
lowers the speed, so it takes longer for the pitch to change
between notes, making the effect more noticeable.
Be sure to hold down the PORTAMENTO button while
changing this setting, otherwise it will not work. Pressing
both VALUE buttons + and – simultaneously returns
the setting to the default value of 3.
The PORTAMENTO setting is retained even when power
is turned off.
