EXi: STR-1 Plucked String
244
Frequency Offset [–10.0 Hz … +10Hz]
This adjusts the pitch by increments of 0.1 Hz. 
Frequency Offset is different from Tune in that, when 
used to detune the two oscillators, it can create a 
constant beat frequency across the range of the 
keyboard.
Pitch Slope [-1.00…+0.00…+2.00]
Normally, this should be set to the default of +1.00.
Positive (+) values cause the pitch to rise as you play 
higher on the keyboard, and negative (–) values cause 
the pitch to fall as you play higher on the keyboard.
When this is set to 0, playing different notes on the 
keyboard won’t change the pitch at all; it will be as if 
you’re always playing C4. This can be useful for 
special effects sounds, for instance.
If you want to create more complex effects, you can use 
one of the Key Track generators as a source for Pitch 
Modulation AMS.
Ribbon [-60…+60 semitones]
You can use the ribbon controller for pitch-bend. This 
parameter specifies, in semitones, the ribbon’s pitch-
bend range. 
Positive (+) values make the pitch rise when you press 
the ribbon controller to the right of center, and 
negative (–) values will cause the pitch to fall.
When you lift off of the ribbon, the pitch will snap back 
to the center (unless you’re using the SW1/2 “Ribbon 
Lock” feature). So, by tapping on the right edge of the 
ribbon and then releasing quickly, you can create 
guitar-style “hammer-on” effects.
JS+X [-60…+60 semitones]
This sets the maximum amount of pitch bend, in 
semitones, when you move the joystick to the right. 
For normal pitch bend, set this to a positive value.
JS-X [-60…+60 semitones]
This sets the maximum amount of pitch bend, in 
semitones, when you move the joystick to the left. For 
normal pitch bend, set this to a negative value.
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 “AMS (Alternate 
Modulation Source) List” on page 967.
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.
