LFO Modulation
The LFO output signal controls the VCF
Cutoff Point, therefore, a growl or wah
effect can be obtained.
HPF
Polarity Switch
This is to set the Cutoff Point of the
HPF.
*The HPF (High Pass Filter) is the filter
that passes high frequency harmonics
and cuts off the low frequency harmo-
nics,
Z
This is to select the polarity of the Enve-
lope curve. Usually A may be used. In
\~mode, ADSR pattern will be in-
verted, therefore, pitch alteration, too.

This is where the volume (amplitude) of the sound is controlled. Normally, it is control-
led by the output voltage from the ENV.
Movement
This is to adjust the volume level in the
writing mode. [NOTE 4]

This is to select whether to control the
VCA by the signal from the ENV (7 )
or by the Gate signal ( TL).
{NOTE 4]
Setting this VCA level too high may cause sound distortion.
