ELEMENT TONE LFO (Low Frequency Oscillator) AM Depth, PM Depth, Type, Delay, Rate & Speed l AM (Amplitude Modulation Depth) ET LFO ABCD AM= 0 PM= 0 Summary: Determines the maximum amount of amplitude modulation that can be applied to the selected element by the modulation wheel or keyboard after touch. Settings: 0 ... 15 Procedure: Use the [4] and [6] cursor keys to select the AM parameter. Use the [-1/NO] and [+1/YES] keys to set the desired degree of amplitude modulation. Details: A " 0 " setting produces no modulation while a setting of " 1 5 " produces maximum modulation. Amplitude modulation produces a periodic variation in the volume of the sound, thus creating a tremolo effect. Please note that the AM parameter of the WHEEL and/or AFTER TOUCH function in the VOICE COMMON edit mode must be set to " o n " before amplitude modulation can be applied manually (see page 7). Amplitude modulation is applied automatically when these parameters are off. l PM (Pitch Modulation Depth) ET LFO ABCD AM= 0 PM= 0 Summary: Determines the maximum amount of pitch modulation that can be applied to the selected element by the modulation wheel or keyboard after touch. Settings: 0 ... 31 Procedure: Use the [4] and [6] cursor keys to select the PM parameter. Use the [-1/NO] and [+1/YES] keys to set the desired degree of pitch modulation. Details: A " 0 " setting produces no modulation while a setting of " 3 1 " produces maximum modulation. Pitch modulation produces a periodic pitch variation, thereby creating a vibrato effect. Please note that the PM parameter of the WHEEL and/or AFTER TOUCH function in the VOICE COMMON edit mode must be set to "on" before pitch modulation can be applied manually. Pitch modulation is applied automatically when these parameters are off. l Type ET LFO ABCD AM= 0 PM= 0 Summary: Determines the waveform of the LFO for the selected element. Settings: SAW UP SAW DOWN TRIANGLE SQUARE SAMPLE&HOLD Procedure: Use the [4] and [6] cursor keys to select the waveform parameter. Use the [-1/NO] and [+1/YES] keys to select the desired LFO waveform. Details: = Upward sawtooth. = Downward sawtooth. = Triangle. = Square. = Sample and hold. 22

ELEMENT TONE

LFO (Low Frequency Oscillator) AM Depth, PM Depth, Type, Delay, Rate & Speed
●
AM (Amplitude Modulation Depth)
ET LFO
ABCD
AM= 0 PM= 0
Summary:
Determines the maximum amount of
amplitude modulation that can be applied to the
selected element by the modulation wheel or
keyboard after touch.
Settings:
0 ... 15
Procedure:
Use the [
4
] and [
6
] cursor keys to select
the AM parameter.
Use
the
[–1/NO]
and
[+1/YES] keys to set the desired degree of
amplitude modulation.
Details:
A “ 0 ” setting produces no modulation
while a setting of “15” produces maximum
modulation. Amplitude modulation produces a
periodic variation in the volume of the sound,
thus creating a tremolo effect.
Please note that the AM parameter of the
WHEEL and/or AFTER TOUCH function in the
VOICE COMMON edit mode must be set to
“on” before amplitude modulation can be
applied manually (see page 7).
Amplitude
modulation is applied automatically when these
parameters are off.
●
PM (Pitch Modulation Depth)
ET LFO
ABCD
AM= 0 PM= 0
Summary:
Determines the maximum amount of
pitch modulation that can be applied to the
selected element by the modulation wheel or
keyboard after touch.
Settings:
0 ... 31
Procedure:
Use the [
4
] and [
6
] cursor keys to select
the
PM
parameter.
Use
the
[–1/NO]
and
[+1/YES] keys to set the desired degree of pitch
modulation.
Details:
A “ 0 ” setting produces no modulation
while a setting of “31” produces maximum
modulation.
Pitch
modulation
produces
a
periodic pitch variation, thereby creating a
vibrato effect.
Please note that the PM parameter of the
WHEEL and/or AFTER TOUCH function in the
VOICE COMMON edit mode must be set to
“on” before pitch modulation can be applied
manually. Pitch modulation is applied automati-
cally when these parameters are off.
