Pitch EG determines how each note will change in pitch over time. This
pitch change can also be affected by the note number or by key velocity.
LFO signal can be used to create vibrato (by modulating operator pitch)
or tremolo (by modulating the output level of a carrier operator) or wah-
wah (by modulating the output level of a modulator operator). The amount
of pitch modulation or amplitude modulation from the main LFO can be
regulated by a controller. In addition, the FM block of an AFM element
contains a Sub LFO that can be used to modulate the pitch independently
of the main LFO.
The pitch of all operators can be controlled directly using the pitch bend
wheel and/or aftertouch.
As indicated by the "AWM" in the oval at the far left of the diagram, an
AWM digital sample can be used to modulate an FM operator. This is
one of the most significant features of the SY99's tone generation system.
The filter block can be controlled in various ways to modify the tone of the sound.
Each note can be given a fixed pattern of tonal change by using the filter EG, and
this can be also affected by the note number or key velocity. Wah-wah (filter
modulation) can be created using the LFO, and wah-wah depth can be regulated
by a controller. The tone can also be directly affected by a controller.
The filter blocks of AFM and AWM elements are identical.
The amplifier block can be controlled directly by an assigned controller. Since the
change in volume over time of an AFM element is determined by the EGs of
carrier operators in the FM block, the amplifier block of an AFM element does
not have its own EG.
The pan block can be controlled in various ways to move the sound between left
and right outputs. Each note can be given a fixed pattern of panning by using the
pan EG, and this panning can be further affected by either note number, key
velocity, or LFO.
The pan blocks of AFM and AWM elements are identical.
