1. (F3) AFM algorithm (Input level)
JUMP #233
In1 Level, In2 Level (0...7): Adjust the input
level of Inl and In2 for each operator.
If an operator input is not used, the Src will dis-
play "off" and the "Level will display "-". The
cursor cannot be moved to the Level setting for
such operators.
Summary; Set input levels Inl and In2 for each
operator.
Procedure:
From: AFM Element job directory (JUMP #230)
Select: job 01: Algrthm. and press (JUMP #233)
F3 (Inpt)
Specify: the input level for each operator input
Remarks: Previous FM synthesizers allowed you
to set only the output level of each operator.
However on the SY99, the input levels In1 and
In2 of each operator can also be set. If the input
source is the feedback from another operator, the
input level setting functions as the feedback
level.
Correct adjustment of input levels is espe-
cially important when bringing in AWM to AFM
as a modulator.
In1 Src, In2 Src: This displays the input sources
for input In1 and In2 of each operator, as deter-
mined by Algorithm and Feedback settings (Fl)
and External input settings (F2). The input
sources cannot be changed from this job.

2. AFM oscillator
JUMP #235
Summary: Set frequency-related parameters for
each operator.
Procedure:
From: AFM Element job directory (JUMP #230)
Select: job 02:Osclltr (JUMP #235)
Operator (1-6): This displays the operator being
edited. To move to another operator, use the
OPERATOR SELECT
buttons OP1...OP6.
Freq Mode (fixed, ratio): When "fixed" is
selected the operator will produce the same
pitch regardless of what note is played. When
"ratio" is selected the operator pitch will
depend on the note that is played
Coarse/Fine (0 Hz...9762 Hz in Fixed Fre-
quency mode, 0.5...61.69 in Ratio Frequency
mode): This setting specifies the pitch produced
by the operator. By moving the cursor to coarse
or fine you can adjust the pitch in large steps or
in small steps. When the Freq Mode is set to
"fixed" the range is 0 Hz...9762 Hz. When the
Freq Mode is set to "ratio" the range is
0.5...61.69. (In "ratio" mode with a Coarse/Fine
setting of 1.0 the A3 key will produce the stan-
dard pitch of 440 Hz.)
Detune (-15...+15): The pitch of each operator
can be adjusted in fine steps of 1.171875 cents.
Waveform (1...16): Each operator can produce
sixteen different waveforms; a sine wave with
no harmonics, and fifteen other more complex
waveforms containing additional harmonics. This
allows you to create complex waveforms using
fewer operators. A graphic display of the
selected waveform is shown below the wave-
form number. The table below shows the har-
monic content of each waveform.
Phase Sync (on, off): When phase sync is on,
the selected waveform will be re-started each
time a key is pressed.
