Parameter Guide
TONE
JD-800
* The CCs that are supported dier with each partial (p. 14).
Parameter Value Explanation
Partial switch OFF, ON
These buttons turn the partials on/
o, and select which partials are to
be stacked when played.
Active switch OFF, ON
Selects the partials to edit. Any
edits you make apply to all selected
partials.
Velo curve 1–4
You can select from one of four
curves, which aect how much
each type of envelope is applied
according to how hard you play
the keys. The envelopes that are
aected include the PITCH ENV, TVF
ENV and TVA ENV.
Hold ctrl OFF, ON
Sets whether the sound of the
partial is sustained (held) when you
operate the hold pedal.
LFO1
LFO1:
Waveform
TRI, SAW, SQU,
S&H, RND
These buttons set the LFO
waveform.
LFO1:
Rate sync OFF, ON Turn this on to sync the LFO cycle
with the tempo.
LFO1:
Rate 0–100
When Rate sync is o, the LFO cycle
is set irrespective of the tempo. The
larger the value, the shorter the LFO
cycle.
When Rate sync is on, the LFO cycle
is set to a note length.
LFO1:
Rate nt
1/64T, 1/64,
1/32T, 1/32,
1/16T, 1/32.,
1/16, 1/8T,

1/4T, 1/8., 1/4,
1/2T, 1/4., 1/2,
1T, 1/2., 1, 2T,
1., 2, 4
LFO1:
Delay time 0–100, REL
Sets the time it takes before the LFO
eect begins after you press a key.
The larger the value, the longer it
takes for the LFO eect to start after
you play the keyboard. The setting
above 100 is“REL.”The“REL” setting
makes the LFO start right after you
release the key.
LFO1:
Fade time -50–+50
Sets the time-based change of the
LFO as it takes eect.
Set this to “+” to make the LFO
amplitude gradually ramp up to
maximum.
Set this to “-” to make the LFO
amplitude gradually ramp down
to zero.
No time-based change occurs
when this is set to“0.”The larger
the absolute value, the more time
required for change.
LFO1:
Oset -, 0, +
Moves the center value for the
LFO waveform (the pitch or cuto
frequency) up or down.
LFO1:
Key trig OFF, ON
Sets whether to synchronize the
start of the LFO cycle with the
timing you use to play the keys
(“ON” to synchronize, “OFF” to
disable).
LFO2
LFO2:
Waveform
TRI, SAW, SQU,
S&H, RND
These buttons set the LFO
waveform.
Parameter Value Explanation
LFO2:
Rate sync OFF, ON Turn this on to sync the LFO cycle
with the tempo.
LFO2:
Rate 0–100
When Rate sync is o, the LFO cycle
is set irrespective of the tempo. The
larger the value, the shorter the LFO
cycle.
When Rate sync is on, the LFO cycle
is set to a note length.
LFO2:

1/2T, 1/4., 1/2,
1T, 1/2., 1, 2T,
1., 2, 4
Rev Delay time 0–100, REL
Sets the time it takes before the LFO
eect begins after you press a key.
The larger the value, the longer it
takes for the LFO eect to start after
you play the keyboard. The setting
above 100 is“REL.”The“REL” setting
makes the LFO start right after you
release the key.
LFO2:
Fade time -50–+50
Sets the time-based change of the
LFO as it takes eect.
Set this to “+” to make the LFO
amplitude gradually ramp up to
maximum. Set this to “-” to make
the LFO amplitude gradually ramp
down to zero.
No time-based change occurs
when this is set to“0”. The larger
the absolute value, the more time
required for change.
Velo Oset -, 0, +
Moves the center value for the
LFO waveform (the pitch or cuto
frequency) up or down.
LFO2:
Key trig OFF, ON
Sets whether to synchronize the
start of the LFO cycle with the
timing you use to play the keys
(“ON” to synchronize, “OFF” to
disable).
WAVE
WG:
Waveform WAVEFORM Sets the waveform that sounds.
WG:
Wave gain
-18dB, -12dB,
-6dB, 0dB,
+6dB, +12dB
Sets the waveform gain (amplitude).
The value changes in units of 6dB
(decibels). Raising the value by 6dB
increases the gain by a factor of two.
WG:
Pitch coarse -48–+48 Shifts the pitch in units of a
semitone.
WG:
Pitch ne -50–+50 Finely adjusts the pitch in units of
one cent.
WG:
Pitch random 0–100
Sets the width of change at which
the pitch randomly changes with
each key press. To disable this
random change, set this to“0.”
WG:
Pitch KF
-100%, -50%,
-20%, -10%,
-5%, 0%, +5%,
+10%, +20%,
+50%, +98%,
+99%, +100%,
+101%,
+102%,
+150%, +200%
Sets the width of pitch change
when the key is shifted one octave
(12 keys) up.
To make the pitch change over one
octave like regular keyboards, set
this to“+100.”To make the pitch
change two octaves over the range
of one octave, set this to“+200.”Set
this to a negative value to make the
pitch go down as you play higher
notes.
To play the same pitch no matter
which key you press, set this to“0.”
