Low Frequency Oscillator (Lfo) Modulation Depth; Amplitude/Pitch/Cutoff - Yamaha SY55 Product Manual

Phase
Summary: Determines at which point in the LFO
waveform the LFO will begin operation for the
selected element.
Settings: 0 ... 99
Procedure: Use the
select the Phase parameter. Use the [DATA EN-
LOW FREQUENCY OSCILLATOR MODULATION DEPTH,
Amplitude Modulation Depth
Summary: Determines the amount of amplitude
modulation applied to the selected element.
Settings: 0 ... 127
Procedure: If the
("AMOD") parameter is not already selected,
use the and
the [DATA ENTRY] control, [-1/NO] and [+1/YES]
keys, or numeric and [ENTER] keys to set the
desired degree of amplitude modulation.
Pitch Modulation Depth
Summary: Determines the amount of pilch modula-
tion applied to the selected element.
Settings: 0 ... 127

numeric and [ENTER] keys to set the desired LFO
phase.
Details: If the LFO is used for pitch modulation, for
example, a phase setting of "0" would cause the
vibrato effect to begin with an upward pitch
sweep, while a setting of "55" would cause the
vibrato to begin with a downward pitch sweep.
The change can be subtle, and experimentation
is the best way to find the best setting.
Refer to: "SENSITIVITY (VELOCITY, AMPLI-
TUDE & PITCH MODULATION," page 67.
Details: A "0" setting produces no modulation while
a setting of "127" produces maximum modula-
tion. Amplitude modulation produces a periodic
variation in the volume of the sound, thus creat-
ing a tremolo effect.
Please note that the amplitude modulation
sensitivity parameter (see page 68) must also be
set to an appropriate value before amplitude
modulation can be applied.
Refer to: "Amplitude Modulation Sensitivity" on
page 68.
Procedure: Use the
select the Pitch Modulation ("PMOD") parame-
ter. Use the [DATA ENTRY] control or [+1/YES]
and [-1/NO] keys, or numeric and [ENTER] keys
to set the desired degree of pitch modulation.
Details: A "0" setting produces no modulation while
a selling of "127" produces maximum modula-
tion. Pitch modulation produces a periodic pitch
variation, thereby creating a vibrato effect.
