1. (F2) AFM algorithm (External input)

Summary: Modulate an operator from an external
source such as AWM waveform or the noise
generator.
Procedure:
From: AFM Element job
directory
Select: job 01:Algrthm., and press
F2 (Extn)
Specify: noise and/or AWM input for each
operator
Noise (off, in1, in2): The SY77 contains a noise
generator which produces a type of white noise.
This can be sent to any free operator input to
modulate the operator.
AWM (off, in1, in2): If the voice contains both
AFM and AWM elements (ie., if the voice mode
is either 9:1AFM&1AWM
10:2AFM&2AWM), an AWM waveform can be
received at any free operator input to modulate
the operator.
For voice mode 9:1AFM&1AWM, the wave-
form of AWM element 2 will be used to modu-
late AFM element 1. For voice mode
AFM ELEMENT DATA
Summary: Set input levels In1 and In2 for each
operator.
Procedure:

element 3 will be used to modulate AFM ele-
ment 1, and the waveform of AWM element 4
will be used to modulate AFM element 2.
and

will be displayed. If both inputs are already used
because of a feedback assignment, "use" will be
displayed. The cursor cannot be moved to the
Dst setting for such operators.
Remarks: Noise modulation makes it possible to
create sounds that were difficult for previous FM
synthesizers.
By using an AWM waveform to modulate
or
one or more AFM operators, new harmonics can
be added to the AWM sample. A simple
example of this is given in Using RCM Hybrid
Synthesis in the appendix.
IN1 Src, In2 Src: This displays the input sources
for input Inl 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.
