Tone Parameters
WG Form (Waveform)
fig.09-21(LCD_PART1-FORM)
Wave (Waveform)
Selects the waveform of the synthesizer sound generator.
Value:
SQU, SAW
* A sawtooth waveform is produced by processing a square Waveform at
the TVF, that is, all the waveform are square at WG even when a
sawtooth is selected.
PCM (PCM Wave Number)
This selects one of the 127 different sampled waves of the PCM sound generator. (p. 86)
Value:
1–127
WG PW (WG Pulse Width)
fig.09-22(LCD_WgPw)
fig.09-23(PulseWidth)
PW (Pulse Width)
A square waveform has exactly the same width, up and down but
a Pulse waveform has different widths. The ratio of upper width
to lower is called pulse width. Depending on the set pulse width
value, the harmonic content of the sound changes greatly.
Value:
0–100
* When a
sawtooth
is selected with
WG Waveform
, pulse width 50%
raises the pitch by an octave.
