Dry Level; Pulse Width; Pwm Depth (Pulse Width Modulation Depth); Pitch Coarse - Yamaha EX5 Owner's Manual

Dry Level

Sets the output level for the original input signal. A
setting of "0" produces no output. Settings with the
negative values reverse the phase of the waveform.
Settings: –64~0~+63

The same as the one in the EP Pickup. See page 126
for information.
04: PWM (Pulse Width Modulation)
PWM is a sort of chorus effect, similar to the pulse
width modulation found on an analog synthesizer.
Generally, a pulse (square) wave can be obtained by
taking the difference between a phase shifted saw-tooth
wave and the original wave, and by modulating the
delayed phase of the resultant wave using LFO and/or
EG. Utilizing this principle, the frequency
characteristics similar to a comb (comb filter), the
PWM type allows you to simulate the pulse width
modulation of VCO. Chorus effects similar to the
conventional pulse width modulation can be added,
since this program decrease specific harmonics on any
type of the input signal. The LFO can be set for each
individual note or for all notes at one time, while EG
can be set for each individual note.

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. In
general this should be adjusted to the basic pitch of
the input signal.
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.
Settings: –32~0~+64
When obtaining the pulse width modulation, set this
value to "+32."
Pulse Width
Adjusts the width of the pulse wave. When the Pulse
Width is set to a value of "64," the pulse wave is
equally balanced, generating only odd-numbered
harmonics. When the value is increased or decreased
from "64," the pulse width will be narrower,
producing the sound with more harmonics (page 116).
Settings: 0~64~127(0%~50%~99%)

PWM Depth (Pulse Width Modulation Depth)

Sets the depth of the pulse width modulated by the
LFO and EG.
Settings: –64~0~+63
PWM DepthVel (Pulse Width Modulation Depth
Velocity)
Sets the velocity sensitivity for the PWM depth. The
PWM Depth can be controlled by the velocity at
which the note played on the keyboard.
Settings: –64~0~+63
LFO Mode (Low Frequency Oscillator Mode)
Sets the LFO mode (the way in which the LFO
functions). There are three types of modes.
Settings:
common:
The LFO functions the same for all notes. In general this
mode should be selected for the pulse width modulation.
key reset:
The LFO functions for each individual note. Each time a
note is played, the phase of the LFO wave will be reset.
random:
The LFO functions for each individual note. Each time a
note is played, the phase of the LFO wave will change
randomly.
