07: Self FM
Self FM lets you add extra richer harmonics to the
sounds. The mechanism how the Self FM type is
formed is as follows: first, input signals are sent to the
delay unit. Next, the phases of each signal sent from
the delay unit are modulated (phase/frequency) by the
input signals themselves, to cause the waves distorted.
Consequently, extra harmonics are obtained.
The underlined items in the diagram are available as the
Destination parameters for the FDSP Controller set (page
141).
■ Pitch Coarse
Adjusts the length of the delay in semitones. A
setting of “0” produces the delay length
corresponding to the pitch of C3 = 261.63Hz.
Decreasing the value increases the depth of the
modulation. If the input signal’s basic pitch is
lowered an octave (–12), the length of the delay will
be twice as long. A setting of (–24) will lower the
pitch two octaves, and the length of the delay will be
four times as long.
❏ Settings: –64~0 (C3)~+63
■ KeyFollow
Sets the KeyFollow for the delay length. This
KeyFollow function controls the length of the delay
in accordance with the notes played on the keyboard.
When set to “+32,” the KeyFollow functions at
100% and the length of the delay moves in inverse
proportion to the pitch played on the keyboard.
When set to a value of “0” the length of the delay is
fixed. To prevent the effect from being irregular, the
value should be set at “+32” normally.

■ Polarity
Sets the direction of the modulation of the input
signal. There are two settings, positive (0) and
negative (1).
❏ Settings:
0 (positive): The delay increases as the input signal
increases.
1 (negative): The delay decreases as the input signal
increases.
■ Phase
Sets the center position of the phase of the input
signal for modulation. Timbre will change depending
on the designated position.
❏ Settings: 0~127
■ Drive
Sets the depth of the modulation.
❏ Settings: 0~127
■ Drive K.Flw (Drive KeyFollow)
Sets the KeyFollow for the Drive. The Drive
KeyFollow function controls the depth of the
modulation in accordance with the notes played on
the keyboard. When set to a positive value, the
higher the note played on the keyboard, the deeper
the modulation becomes. When a negative value is
set, the lower the note played, the deeper the
modulation becomes.
❏ Settings: –64~0~+63
■ Drive EG (Drive EG Depth)
Sets the EG depth to affect the depth of the
modulation.
❏ Settings: –64~0~+63
■ Drive EG Vel (Drive Envelope Generator
Velocity)
Sets the velocity sensitivity for the Drive EG. The
EG depth can be controlled by the velocity at which
the note played on the keyboard.
❏ Settings: –64~0~+63
■ LPF (Low Pass Filter)
Sets the cutoff frequency which cuts the higher
range of the input signals for modulation.
❏ Settings: 0~127
