PROGRAM > STR-1: String 4–3: PCM OSC Pitch
217
4–3b: Portamento
Portamento lets the pitch glide smoothly between notes,
instead of changing abruptly.
Portamento and MIDI
If Portamento is either enabled for both the String and the
PCM, or off for both, then MIDI CCs 5 (Portamento Time)
and 65 (Portamento on/off) affect both the String and the
PCM.
If Portamento is enabled for only one of the two, only that
element can be affected by the MIDI CCs. The other element
will always have Portamento off, regardless of the MIDI
CCs.
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.
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.
4–3c: LFO
LFO Select [LFO 1, LFO 2, LFO 3, LFO 4,
Common LFO]
This selects an LFO to modulate the PCM Oscillator’s pitch.
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.
Both the String and PCM Pitch LFO Intensities are scaled by
MIDI CC#77.
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 [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.
4–3d: Pitch EG
EG Select [EG 1 (Filter), EG 2 (Pitch),
EG 3, EG 4, Amp EG]
This selects an EG to modulate the PCM Oscillator pitch.
There are four assignable EGs, in addition to the Amp EG.
Each of these can be used as a modulation source to control a
wide variety of parameters.
In the midst of all this flexibility, we thought it would also be
good to provide a little structure. With this in mind, EG 1 is
named EG 1 (Filter) and EG 2 is labeled EG 2 (Pitch).
Please take these names as suggestions, rather than
restrictions. If you like, you’re free to use these EGs to
control any EG or AMS destination, or to use other EGs to
control Filter Frequency and Pitch.
Intensity [-48.00…+48.00]
This controls the initial effect of the Pitch EG on the PCM
Oscillator, in half-steps, before any AMS modulation.
