OUTLINE OF TONE PARAMETERS
a.
WG
(Wave
Generator)
b.
TVF
(Time
Variant
Filter)
In the
WG
(Wave
Generator), the pitch
and waveform
are controlled.
©Pitch
The
basic pitch
of
a Partial
(sound
generator) can be
set
here.
The
pitch
is
a
Common
parameter, and
is
therefore controlled
by
©
P-ENV
and
©
LFO-1.
©Waveform (PCM Wave
Number)
This
selects the
waveform
of the
sound
source.
When
a
synthesizer
sound
generator
is
selected,
the
waveform
can
be
controlled
by
the
©
Pulse
Width
controls.
©Pulse
Width
This changes
the
waveform
of
the
sound
source.
The
pulse width
is
controlled
by any
LFO
(
= Common
parameter).
This
filter
passes lower frequency harmonics and
cuts
off
the higher
ones.
By
changing
the cutoff point
and
the resonance, the
waveform
changes.
©Cutoff
Frequency
This sets the cutoff point.
The
cutoff point
can be
controlled by
©TVF
ENV
and any
LFO
(
= Common
parameter).
©Resonance
This emphasizes the cutoff point,
making more
unusual
or electronic
sounds.
c.
TVA
(Time
Variant Amplifier)
This
controls the
volume
of the Partial.
D
Level
This determines
the
volume
of the
sound.
When
a
synthesizer
sound
generator
is
used, the
level
can be
controlled
with
the
®
TVA ENV
and any
LFO (Common
parameter).
When
a
PCM
sound
generator
is
used, the
©TVA
ENV
controls the
level.
