Pitch bend smoothly changes the pitch upward or
downward, similar to how a guitarist can "bend"
strings. On the KROME, you will normally use the
joystick to control pitch bend in realtime.
The JS (+X) and JS(–X) settings specify the amount of
pitch change (in semitones) that will occur when MIDI
pitch bend messages are received or when the joystick
is moved to left or right. A setting of +12 allows the
pitch to be controlled a maximum of one octave
upward; a setting of –12 allows the pitch to be
controlled a maximum of one octave downward.
Note: You can also control pitch bend using a
controller other than the joystick, or via MIDI.
Ribbon (#16) specifies the amount of pitch change (in
semitone units) that will occur when MIDI control
change message #16 is received. With a setting of +12, a
value of 127 will raise the pitch one octave, and a value
of 0 will lower the pitch one octave.
You can use an LFO to create vibrato.
LFO1 Int. or LFO2 Int. sets the depth of how the
selected LFO will affect the pitch. With a setting of
+12.00, vibrato will produce a maximum of ±1 octave of
JS+Y Int specifies the amount of vibrato that the LFO
will produce when the joystick is pushed away from
Intensity (AMS Intensity) specifies the depth of
vibrato that will be applied by the LFO when
modulated by the selected AMS (Alternate Modulation
Source). For example, if the panel switch assignment
for SW1 is set to SW1 Mod. (CC#80) (Prog 1–7a), and
you set LFO1 AMS to SW1: CC#80 and specify an
appropriate value for Intensity, vibrato will be applied
when you turn SW1 on or when MIDI control change
#80 is received.
When the Intensity value is set to +12.00, the pitch EG
specified in the Pitch EG page will produce a
maximum of ±1 octave of pitch change.
To realistically simulate the slight change in pitch that
occurs when a string is plucked or at the attack of a
brass or vocal sound, you can use the EG to create a
subtle change in pitch at the attack.

Portamento makes the pitch change smoothly when
you play the next note before releasing the previous
The Time parameter controls how long it will take the
pitch to change. As this value is increased, the pitch
will change over a longer time. With a value of 000,
there will be no portamento.
You can turn Portamento on and off via SW1 or SW2,
by assigning them to Porta.SW CC#65.
