ELEMENT TONE
LFO (Low Frequency Oscillator) AM Depth, PM Depth, Type, Delay, Rate & Speed
• AM (Amplitude Modulation Depth)
• Type
• PM (Pitch Modulation Depth)
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 [ ] and [ ] 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.
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 [ ] and [ ] 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.
Summary: Determines the waveform of the LFO for
the selected element.
Settings:
Procedure: Use the [ ] and [ ] cursor keys to
select the waveform parameter. Use the
[-1/NO] and [+1/YES] keys to select the de-
sired LFO waveform.
