FC (Foot Control)
This sets the parameters controlled by a Foot Controller
connected to the FOOT CONTROLLER jack on the rear panel.
There are three parameters: FMOD (Filter Modulation), CUTOFF,
and VARI EF (Variation Effect).
Filter Modulation Cutoff
Variation Effect
FMOD (Filter Modulation): Sets the filter modulation depth
created by the LFO (Low Frequency Oscillator). The value set here
will determine the range of the filter modulation by the Foot
Controller. Pressing the Foot Controller will increase the depth of
the filter modulation.
CUTOFF: Sets the range of the cutoff frequency points above
which other frequencies are cut off. The value set here will
determine the range of the cutoff frequency points by the Foot
Controller. Pressing the Foot Controller will raise the cutoff
frequency point (i.e., make the voice brighter).
VARI EF (Variation Effect): Determines the Variation effect range
set by the EFFECT parameters (page 23), controlled by the Foot
Controller.
NOTE
For details about which parameters the Foot Controller can
control, see the Effect Parameter List on page 49.
Settings:
FMOD (Filter Modulation): 0~127
CUTOFF: -64 ~ +63
VARI EF (Variation Effect): -64 ~ +63
PORTA (Portamento)
This sets the Portamento function. Portamento continuously
changes the pitch from one note to the next, thus letting you
glide the pitch from one note to the next. There are two
parameters, SWITCH and TIME. Values can be set for each Layer.
Switch
SWITCH: Turns the Portamento on or off. (for each layer)
TIME: Sets the time it takes for the pitch to reach the next note
played. (for all layers)
Settings:
SWITCH: on, off
TIME: 0~127
ASSIGN1 PARAM (ASSIGN 1 Parameter)
This determines which parameter will be controlled by the
ASSIGN 1 Sound Control Knob. You can choose from 28 types of
parameters.
The parameter assigned to the ASSIGN1 knob as the default
differs depending on the Performance selected.
Settings:
For details about each parameter, see the reference pages as
listed on the next page.
