Use the square wave to trigger the
AD ENV 1
(we have done it before);
modulate between them (xmodulation) and use the output to modulate an
oscillator, modulate them with the envelope outputs; use the triangle and
sine waves to modulate slightly the oscillators and detune them, use them
to modulate the VCAs and the
VCF
to create movement, …
VCF
Many people say that the
VCF
(Voltage
Controlled Filter) is the soul of a synth. It may
be excessive, but not without a reason. Each
filter have its own character and shapes the
waves in very different ways. The
ANTS!
VCF
is a not an exception: Analog, resonant,
modular, low pass and high pass, with
overdrive and a built-in mixer.
FILTER BASICS
A filter is used to remove frequencies. The
FREQ
(frequency or CUT-OFF)
determines the position in the harmonic spectrum where the filter will
begin to filter. A Low Pass Filter will filter (block) the high frequencies while
a High Pass Filter will block the low frequencies. In a
VCF
we can control the
frequency with an external voltage, hence the name “Voltage Controlled
Filter”.
As you can see in the drawing the filter start to filter the frequencies
starting from the FREQUENCY or CUT-OFF point. Before it there is the
Pass
Band
, where all the frequencies are sounding. The
Transition Band
is the
zone where the frequencies are removed gradually. This rate is called the
slope, which is measured in decibels per octave. The
VCF
has 12db/oct in
