FREQ
Setting the VCF to the “H” end
allows upper harmonics to pass,
thereby creating a bright tonality.
Moving the control towards the
“L” end of the scale gradually cuts
off more and more harmonics,
creating a softer tonality.
RESO
Set to the “H” position frequencies
near the lter cut off frequency are
emphasized for a “sharper” sound.
When set high the lter will self
resonate (level will decreased as
the input signal is increased).
KBD (Back panel)
Control the cut off by following the
signal of notes played.
VEL SENS (Back panel)
Control the cut off by following the
velocity of of notes played.
TRIMMERS (Small panel holes)
Fine tune the cut off frequency.
This is convenient for ne tuning
when using the VCF as an sine
wave oscillator by self oscillation.
VCA LEVEL
This knob determines to what
degree EG1, EG2 or LFO2 affects
the level of the sound (dB). Chose
which source to use with the 3 way
selector below.
The Voltage Controlled Filters alters the sound by cutting off frequencies. Voltage Controlled Amplier
VCF 1 & 2 VCA
FREQUENCY
24dB/oct MOD & SRC
Determines to what degree the
signal of the EG or LFO affects
the VCF cut off frequency. This
permits creation of a broad range
of interesting time-based tonal
variation effects.
