Yamaha SY99 Owner's Manual page 320

The SY99 has "channel" aftertouch, which
produces a single pressure value for the entire
keyboard; it does not have "polyphonic" after-
touch. However, its Zoned Aftertouch capability
allows you to restrict the effect of aftertouch to a
specified zone or note, in this way providing
much the same expressive possibilities as poly-
phonic aftertouch.
Aftertouch can be used to control a wide
variety of parameters. For details, see Common
data 12. Controller set, pages 127 to 130.
Filter sync: When editing a filter in voice edit mode,
you can turn Filter Sync on so that parameter
adjustments made to one filter will affect the
other filter as well (each element has two fil-
ters). This is a convenience for editing, not a
new parameter. For details, see AFM element
data, 8.AFM filter, page 149.
Sequencer capacity: The SY77 sequencer has a
capacity of approximately 16,000 notes. The
SY99 sequencer has a capacity of approximately
27,000 notes.
Switch lock: The Switch Lock function allows you
to lock the front panel switches so that they
cannot be operated accidentally. This may be
convenient when you wish to place books or
sheet music on the SY99 front panel. For de-
tails, see System utility 7.Switch lock, page 257.
MIDI bank select message: The SY99 can trans-
mit and respond to MIDI bank select messages
to select voice memories.
Voice edit element job directories: The AWM
element job directory of the SY99 starts with job
2 (job 1 has been left blank), so that AFM and
AWM element jobs from EG to Filter will have
the same job number (3.EG - 8.Filter). Since
these jobs are similar or identical for both AFM
and AWM elements, it is conceptually helpful for
them to have the same job number.
Other details: There are other differences in the
screen displays and function key assignments.
Most of these differences are due to the addition
of new features to the SY99. However, we have
tried to keep the JUMP numbers for pages the
same whenever possible. Since some of the jobs
in Utility mode have been reordered, this means
the JUMP numbers will not necessarily follow
the sequence of the jobs.
Data compatibility: As mentioned above in AWM
sample memory, the SY99 contains all the SY77
AWM waveform data, but the order has been
rearranged. When SY77 (or TG77) voice data is
loaded into the SY99, the waveform numbers
will be converted automatically, and the SY99
waveform equivalent to the SY77 waveform will
be used. However since minor adjustments have
been made to some of the waveform data itself,
the sound of some waveforms may not be pre-
cisely identical to the SY77 waveforms.
Since the effect systems of the SY77 and
SY99 are significantly different, SY77 voices
which depend heavily on effect processing will
not sound the same on the SY99.
Disk compatibility: If you wish to load an SY77
disk which contains "All Data", "Synthesizer
All" or "Sequencer All" data, or to save "All
Data", "Synthesizer All" or "Sequencer All"
data to a disk which will later be loaded by an
SY77, you must make the appropriate setting for
Disk utility 8.Disk save type (see page 274).
Once the data has been loaded into the SY99 it
can be saved in either format.
All other types of disk data are directly com-
patible.
