F2) Afm Lfo (Sub) - Yamaha SY77 Operating Manual

VOICE EDIT MODE
Wave (triangle, saw down, saw up, square,
sine, sample&hold): This selects the wave
(shape of modulation) produced by the Main
LFO. The selected wave is graphically displayed
in the LCD. When sample&hold is selected, the
LFO will produce a control signal whose level
will change randomly at intervals of time deter-
mined by the Speed setting.
Speed (0...99): The speed of the LFO modula-
tion. Higher settings result in faster modulation.
Delay (0...99): The time delay before the LFO
modulation begins.
Init Phase (0...99): Initial Phase determines the
point of the waveform from which the LFO will
begin when a key is pressed. The LFO wave-
form always starts over again from this initial
phase point when each note is played. An initial
phase setting of 0...99 corresponds to a phase of
0...360 degrees.
A Mod Depth (0...127): Amplitude Modulation
Depth determines how much the LFO will affect
the output level (amplitude) of the operators.
For this setting to have an effect, the
AModSens (amplitude modulation sensitivity)
of an operator must be set above 0. Refer to 5.
AFM sensitivity.
AFM ELEMENT DATA
Summary: The Sub LFO is completely independent
of the Main LFO, but can be used only to create
vibrato (pitch modulation). This will apply
equally to all operators, and is not affected by
pitch modulation sensitivity.

P Mod Depth (0...127): Pitch Modulation Depth
determines how much the LFO will affect the
pitch of the operators. For this setting to have
an effect, the PModSens (pitch modulation
sensitivity) of an operator must be set above 0.
Refer to 5. AFM sensitivity.
F Mod Depth (0...127): Filter Modulation
Depth determines how much the LFO will affect
the cutoff frequency of the filter. For this setting
to have an effect, the Ctrl setting of a filter must
be set to "LFO", and the LFO Cutoff Sens set-
ting must not be 0. Refer to 8. ( F 1 ) AFM filter
(Cutoff frequency).
Mode (delay, decay): When this is is set to
"delay", the Sub LFO will begin after the time
delay specified by
"decay", the Sub LFO will begin fading out after
the time specified by
Wave (triangle, saw down, square, sample&
hold): The wave produced by the Sub LFO.
