How The Sy99 Differs From The Sy77 - Yamaha SY99 Owner's Manual

APPENDIX
Aside from the size of the keyboard and the addition
of an expansion memory slot, the SY99 is externally
similar to the SY77. However, the SY99 has been
enhanced in several ways which you should be
aware of if you have previous experience with the
SY77, or when you wish to port SY77 voices to the
SY99.
Keyboard: The SY77 has a 61 note keyboard. The
SY99 has a 76 note keyboard. (See also Zoned
aftertouch below.)
Master keyboard functions: The SY99 is able to
function as a powerful MIDI master keyboard.
Eight editable master control setups are pro-
vided, each containing four zones that transmit
on their own MIDI channel. Since more than one
master control setup can be simultaneously ac-
tive, the SY99 can independently control 16 dif-
ferent external synthesizers or tone generators,
An output filter is provided to filter each type
of outgoing message for each channel 1-16. For
details, refer to Master control utility, page 284.
AWM (ROM preset) sample memory: The SY77
has 112 waveforms occupying 2 Mwords (4
Mbytes). The SY99 has 267 waveforms occupy-
ing 4 Mwords (8 Mbytes), which include all of
the waveforms of the SY77 and many new
waveforms. (See Data compability below.) A
complete listing of the SY99 waveforms is given
in AWM element job 2 AWM waveform set, page
157.
MDR/sample RAM: The SY99 possesses 512
Kbytes of RAM which can be allocated for use
as MIDI data recorder (MDR) memory or as
sample memory, in any desired proportion. The
allocation procedure is described in Utility
Mode, System utility 5.Memory allocate, page
256.

How the SY99 differs from the SY77

RAM allocated as MDR memory is available
for receiving bulk data dumps from other MIDI
devices. Once received by the SY99, this data
can be saved to a floppy disk using the SY99's
disk drive. The MDR function allows you to use
the SY99's floppy disk capability to store data
for other devices which do not have disk storage
capability.
RAM allocated as sample memory is avail -
able to receive MIDI sample dumps from other
devices (such as Yamaha's TX16W sampler),
or sample data loaded from disk. This sample
data can be assigned to waveforms and used in
the same manner as the samples contained in
the SY99's AWM sample ROM or waveform
cards. For details, refer to AWM element data
2.Waveform set, on page 157.
The amount of RAM available for sample
data can be increased using expansion RAM
kits. Refer to the following section Expansion
RAM in the appendix.
Effect system: The SY77 has two modulation units
(4 effect types) and two reverb units (40 effect
types). The SY99 has two effect units (63 effect
types), each superior in quality. Cascade and
dual effect types are provided, allowing each unit
function as two effect units, each with its own
effect send, and effect unit parameters can be
controlled in realtime. For details, see Voice edit
mode, Common data 10.Effect set, page 104.
Zoned aftertouch: A new voice parameter has
been added to the SY99 which allows you to
specify how aftertouch will affect currently
sounding notes; all (all notes, as on the SY77),
top (only the highest note), bottom (only the
lowest note), split hi (all notes at or above the
specified split point), split lo (all notes below
the specified split point).
