Antidote features four lowpass filter types, which
differ in how strong the damping is per oc-
tave. The one-pole filter will attenuate frequen-
cies above the cutoff by 6 dB, the two-pole by
12 dB, the three-pole by 18 dB, and finally the
four-pole by 24 dB per octave.
•
The band-pass filter damps frequencies around
the cutoff frequency. As a result, bass and treble
get attenuated.

The Bandpass filter attenuates the frequencies
around cutoff by 12 dB per octave.
•
The high-pass filter attenuates all frequencies be-
low the cutoff frequency and passes the higher
frequencies unchanged.

The Highpass filter attenuates the frequencies

• Diode Ladder
This filter is a special kind of low-pass filter,
which models analog filter circuits based on
diodes (or transistors hooked up as diodes). The
response and the resonant tuning of such filters
differs from the standard low-pass filters, and is
useful to recreate some vintage analog sounds.
Of the above filter types, the low-pass filter types are
the most common, as they fully preserve the bass fre-
quencies and allows the natural progression from a
bright to a dark timbre when being modulated.
To modulate the cutoff frequency and produce a dy-
namically changing timbre, the LFOs and filter enve-
lope can be used. Both options will be discussed later
in this chapter.
