PROGRAM > AL-1: OSC/Pitch 4–4: Pitch Common
151
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 .
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.
To do so:
1. Go to the PROGRAM > Basic/X-Y/Controllers–
Controllers page.
2. Under Switch tab, select the RT Control by the Target
of either Switch1 or Switch2, and set the RT Control
to Portamento SW (CC#65).
Now, the selected button will enable and disable Portamento.
It will also send the MIDI Portamento controller, CC#65.
Even if you don’t assign SW1/2 to Portamento, you can
still use MIDI Controller #65 to turn Portamento on and
off.
4–4c: 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.
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.
