Thank you for purchasing the Yamaha SY77 digital synthesizer. The SY77 is the first of a new generation of
Yamaha synthesizers featuring the new Realtime Convolution and Modulation (RCM) hybrid tone generation
system, which uses Advanced FM (AFM) tone generation and Advanced Wave Memory (AWM) tone genera-
tion in conjunction with realtime digital filtering.
The SY77 can function as up to 16 independent synthesizers with dynamically allocated voices, and includes
an on-board 16-track 99-pattern sequencer.
To take full advantage of the SY77 and enjoy long and trouble-free use, please read this manual carefully.
How to use this manual
This manual is divided into three sections; an introductory section, a reference
section, and an appendix.
Introductory section: This section contains the information you need to start
using your SY77 right away.
lIntroducing the SY77: Please be sure to read this section. It will tell you
how to play the sounds, about the main features of the SY77, and about
basic operation.
lHow to use the sequencer: This explains how to use the built-in
sequencer to record your own song of up to 16 parts, with the SY77 func-
tioning as up to sixteen independent instruments.
l
How to edit a Voice: Read this when you want to modify a voice or create
a completely new voice.
Reference section: This section contains a full explanation of all the SY77’s
functions. Once you have worked through the introductory section and are
comfortable with basic operation, glance through this section to get an idea
of the SY77’s capabilities. Refer to the details when necessary.
Appendix:
This section contains technical information that may be of interest to
advanced users or programmers.
Conventions in this manual
In order to present information as clearly as possible, the following conventions
are used in this manual.
lThe names of front panel buttons and controls are set in small capital type;
e.g., press the
EDIT
button.
lItalics are used mainly when referring to a section in this manual; e.g., for
details refer to AFM element job 5. AFM sensitivity.
l
Most of the LCDs in the SY77 have a unique Page Jump number to which you
can jump by pressing
JUMP
and entering the number. These numbers will be
prefixed by a “#” sign; e.g, JUMP #312.
l
Function names will be capitalized when they first occur or when necessary
for emphasis, but will be uncapitalized in subsequent occurrences; e.g., adjust
the LFO Speed ... after adjusting the LFO speed, ...
l
The beginning of each two-page subsection in the introductory section con-
tains a short abstract or summary of the entire subsection, printed in bold
type.
l
Three periods between two numbers are used to indicate that a parameter
can be set to any value in this range; e.g., Velocity Sensitivity (-7...+7).
Since some parameters can be set to negative values, this avoids the possi-
bility of confusing a dash with a minus sign.
