VOICE EDIT MODE
Inl 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.
Remarks: Previous FM synthesizers allowed you
to set only the output level of each operator,
However on the SY77, the input levels in1 and
in 2 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
especially important when bringing in AWM to
AFM as a modulator.
AFM ELEMENT DATA
2. AFM oscillator
JUMP #235
Summary: Set frequency-related parameters for
each operator.
Procedure:
From: AFM Element job (JUMP #230)
directory
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
standard 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.
Init Phase (0...127): This determines the initial
phase position from which the selected wave-
form will be re-started when phase sync is on.
The ink phase range of 0...127 corresponds to a
range of 0...360 degree starting phase. This set-
ting is effective only when Phase Sync is on.
Waveform: The sixteen waveforms that can be
produced by each operator are not modeled after
any "real" instrument but are mathematical
transformations of sinewaves. The following
chart shows the harmonic content of each
waveform. The amplitude of each harmonic
partial is given as a percentage of the funda-
mental.
