Fl) Afm Pitch Eg (Switch) - Yamaha SY77 Operating Manual

Speed (0...99): The speed of the LFO modula-
tion. Higher settings result in faster modulation.
The speed of the sample&hold wave will be
faster than the other waves.
Time (0...99): The time length used for Sub LFO
delay or decay.
P Mod Depth (0...127): The depth of pitch
modulation produced by the Sub LFO.
Wave: The following four waveforms can be
selected for the Sub LFO.
AFM ELEMENT DATA
Summary: The pitch change over time created by
the pitch EG can be switched on/off for each
operator. To set the shape of the pitch EG, see
7. (F2) AFM pitch EG (EG settings).
Procedure:
From: AFM Element job directory (JUMP #230)
Select: job 07:PitchEG and press
F1 (Sw)
Specify: pitch EG switches, scaling, and range
PEG Sw (off, on): When the Pitch EG Switch is
"off for an operator, it will not be affected by
the pitch EG.
Rate Scaling (-7...+7): Pitch EG Rate Scaling
determines how pitch EG rates will change
according to the note played. When this is set to
+1...+7, the pitch EG will be faster for higher
notes. When this is set to -1...-7, the pitch EG
will be slower for higher notes. When this is set
to 0, the pitch EG will be the same rate for all
notes.

Mode and Time: The mode and time settings work
together to determine how the Sub LFO will
begin or end. When Mode=delay the Sub LFO
will begin after the time delay specified by
Time. When Mode=decay the Sub LFO will
affect the sound beginning immediately from
when the key is pressed, but will gradually die
out after the time delay specified by
Velocity Sw (off, on): When this is on, strongly
played notes will cause the pitch EG to change
over a greater range.
Range (1/2 oct, 1 oct, 2 oct, 8 oct): This deter-
mines the maximum range of the AFM pitch EG,
from 1/2 octave to 8 octaves.
PEG Sw: When using the Pitch EG to make the
pitch of a sound change over time, you will
normally turn the PEG switch on for all oper-
ators. If the pitch of a modulator operator
changes while the pitch of another operator it is
modulating remains constant (or vice versa), the
carrier modulator ratio will shift during the
duration of the sound, changing the overtone
structure. This can be an interesting effect in its
own right.
Rate Scaling: This setting determines how Pitch
EG Rates (the speed of pitch change) will be
affected by the key number of each note. The
following diagram shows the result when Pitch
EG Rate Scaling is set to +7. Notice that high
notes have a shorter pitch EG (faster EG rates)
than lower notes.
