V CF (Voltage Controlled Filter)
The output signal goes to the Mixer then to the VCF to be filtered. Each VCF lets lower frequency harmonics pass
and cuts off the higher ones. In other words, it is a regular low pass filter. By controlling the cutoff point and
resonance, the waveform changes, thereby the tone colour alters.

Value
The HPF (High-Pass Filter) is a filter that passes
3
higher frequency harmonics and cuts off the lower
2
ones. As you increase the value, the cutoff point
1
0 goes up, lower frequency harmonics being cut off.
This is for changing the cutoff point of the VCF. As
you decrease the value, cutoff frequency will come
99
down, and the waveform gradually becomes an
approximation of a sine wave, then the sound will
00 fade out.
This emphasises the cutoff point. As you increase
the value, the created sound will become more
unusual, more electronic in nature.
This controls the cutoff point by the waveform
selected at the LFO section. Increasing the value
deepens the modulation.
99
This controls the cutoff point of the VCF of each note
with the ENV curve set in the ENV section. As you
increase the value, tone colour within one note
00
changes more drastically.
This can shift the cutoff point by key position (pitch).
At 100%, it prevents any inconsistency in the
harmonic contents caused by pitch alteration.
