PROGRAM > MOD-7: Oscillator 5–1: Osc Main
317
Intensity [–48.00…+48.00]
This controls the depth and direction of the Pitch AMS
modulation, in semitones.
Pitch Slope Parameter Details
The Pitch Slope graphic appears in the Parameter Details
area when any of the Pitch parameters are selected.
5–1b: Pitch LFO
LFO Select [LFO 1, LFO 2, LFO 3, LFO 4,
Common LFO]
This selects an LFO to modulate all oscillators
simultaneously. This shared modulation can be useful for
vibrato, among other things.
The LFO Intensity, JS+ Y Intensity, and AMS are all
summed together to produce the final amount of LFO pitch
modulation.
LFO Intensity [–48.00…+48.00]
This controls the initial effect of the LFO on the pitch, in
semitones, before any JS+Y or AMS modulation.
Negative (–) settings will invert the phase of the LFO.
JS+Y Intensity [–48.00…+48.00]
Moving the joystick “up” from the center detent position,
away from yourself, produces the JS+Y controller. You can
use this to scale the amount of the LFO applied to the pitch.
This parameter sets the maximum amount of LFO
modulation added by JS+Y, in semitones.
As this value is increased, moving the joystick in the +Y
direction will cause the LFO to produce deeper pitch
modulation.
Negative (–) settings will invert the phase of the LFO. You
can also use this to reduce the initial amount of the LFO, as
set by LFO1 Intensity, above.
Pitch LFO Parameter Details
These items appear in the Parameter Details area when any
of the Pitch LFO parameters are selected.
AMS [List of AMS Sources]
This selects an AMS modulation source to scale the amount
of the LFO applied to pitch.
For a list of AMS sources, see “Alternate Modulation Source
(AMS) List” on page 901.
Intensity [–48.00…+48.00]
This controls the depth and direction of the LFO AMS
modulation, in semitones.
5–1c: Portamento
Portamento lets the pitch glide smoothly between notes,
instead of changing abruptly.
Enable [Off, On]
On (checked): Turns on Portamento, so that pitch glides
smoothly between notes.
Off (unchecked): Turns off Portamento. This is the default
state.
Fingered [Off, On]
This parameter allows you to control Portamento through
your playing style. When it’s enabled, playing legato will
turn on Portamento, and playing detached will turn it off
again.
This option is only available when Portamento Enable is
turned on.
On (checked): Turns on Fingered Portamento.
Off (unchecked): Turns off Fingered Portamento.
Mode [Constant Rate, Constant Time]
Constant Rate means that Portamento will always take the
same amount of time to glide a given distance in pitch - for
instance, one second per octave. Put another way, gliding
several octaves will take much longer than gliding a half-
step.
Constant Time means that Portamento will always take the
same amount of time to glide from one note to another,
regardless of the difference in pitch. This is especially useful
when playing chords, since it ensures that each note in the
chord will end its glide at the same time.
Time [000…127]
This controls the portamento time. Higher values mean
longer times, for slower changes in pitch. When Time is set
to 0, the pitch will be reached instantly–just as if Portamento
Enable was turned Off.
Portamento Parameter Details
These items appear in the Parameter Details area when any
of the Portamento parameters are selected.
AMS [List of AMS Sources]
This selects an AMS source to control the Portamento
Time. For a list of AMS sources, see “Alternate Modulation
Source (AMS) List” on page 901.
The modulation occurs only at note-on. This means that you
can change the time for the next pitch glide, but you can’t
change any glides which are already in progress.
Intensity [-127…+127]
This controls the depth and direction of the Portamento
Time AMS modulation.
Assigning SW1 or SW2 to Portamento On/Off
You can use the two assignable switches, SW1 and SW2, to
turn portamento on and off. For more information, see “1–
8b: Panel Switch Assign” on page 48.
For details on assigning functions, see “Assigning SW1 or
SW2 to Portamento On/Off” on page 151.
5–1d: Macro Edit
Brightness [–100…+100]
This controls the input levels of all Carriers (see “Oscillator
Carrier/Modulator Status,” below).
Brightness Vel. Sens. [–100…+100]
This controls the output level velocity sensitivities of all
Modulators.
Timbre [–100…+100]
This controls the pitches of all Modulators.
