VOICE EDIT MODE
L0-L4 (Key on Levels 0...63): These determine
the levels to which the operator EG will move
while a key is being pressed.
LP (Segment Loop Point S1...S4): This specifies
the segment from which the EG will continue
looping if a key remains-depressed after the EG
has arrived at level L4.
Rl, R2 (KeyOff Rates 0...63): These determine
the speed with which the operator EG will
change levels after a key is released.
AFM ELEMENT DATA
Summary: Set output level and scaling for a single
operator while viewing a graphic display of the
scaling.
Procedure:
From: AFM Element job directory (JUMP #230)
Select: job 04:0utput and press
F1 (Each)
Specify: the output level and scaling for the
selected operator
Output Level (0...127): The output level of the
operator
BP1-4 (Breakpoint 1-4): Note (C-2...G-8) and
Offset (-127...#127) of each Break Point deter-
mine how the output level of each operator will
vary across the keyboard. When the cursor is
located at note, you can press F7 (Kbd) and
press a key to enter the new note setting.
Output Level: This sets the output level of each
operator. The output level of a carrier operator
will affect the volume, and the output level of a
modulator operator will affect the tone. Remem-
ber that the input levels of each operator input
In1 and In2 can also be adjusted as explained in
1. ( F 3 ) Algorithm (Input level) (JUMP #233).
Even if the output level of an operator is raised,
it will have no effect on another operator to
which it is connected if the corresponding input
level of the operator is set at 0.

(JUMP #241)
L1, L2 (KeyOff Levels 0...63): These determine
the levels to which the operator EG will change
after a key is released.
The meaning of these EG parameters is explained in
the previous section 3.1 Operator EG.
In this AFM operator EG (All) display, the
OPERATOR SELECT buttons cannot be used to select
operators.
Break Point: The operator output level can be
made to vary depending on the note that is
played. On most acoustic instruments, notes
differ in volume and tone depending on the range
in which they are played. For example the low
notes of a piano are more tonally complex and
louder than the high notes.
Use the four break points to specify how the
operator output level will be adjusted across the
keyboard.
Offset (-127... +127) determines the output
level adjustment for each of the four points
specified by Note.
The four note settings must be in ascending
order. It is not possible to set a break point
to a note lower or higher than the note set-
tings of the neighboring break points.
The following diagram shows how the oper-
ator output level would be adjusted across the
keyboard for the settings shown in the above
LCD.

Each offset is added to the overall operator out-
put level of 80. For example the offset at break
point 1 (El) is -4, so the resulting operator out-
put level at El is 76. The resulting operator out-
put level is limited to the range of 0... 127.
