Audio Damage Filterstation - Manual (Page 9)

4 POLE LP – Audio Damage‘s own 4-pole low-pass filter. Loosely based on the famous Moog filter, this is the
one to use for overtly electronic-sounding filter effects.
4 POLE HP – a high-pass filter with a steeper cutoff slope than its 2-pole counterpart. If you want to kill the
bass in your sound, this will do the job.
2 POLE NOTCH – that‘s pretty much what it is. Notch filters can create phase-shifter-like effects, particularly if
you use a couple of them with different frequency settings.
LP20, HP20 – emulations of the low-pass and high-pass filters found in the Korg MS-20 analog synthesizer.
These filters have more personality than the 2 POLE LP and 2 POLE HP modes.
914 BP – the bandpass filter from Audio Damage‘s 914 filter bank plug-
in. An accurate recreation of the filters in Moog filter bank
modules, this is a bandpass filter with distinctive phase-
response characteristics.
‘POD LP – the filter from one of Audio Damage‘s first products,
Filterpod. It‘s essentially a low-pass filter with an odd hump
near its cutoff frequency, and some unusual resonance and
overdrive characteristics.
VCA – not really a filter as such. Like the module commonly found in
synthesizers, the VCA mode changes the loudness of signals,
rather than changing their timbre. Changing the filter‘s
frequency parameter of changes the level of the signal. This
means that Filterstation is quite capable of creating a variety of
volume-based effects, such as tremolo, gating, auto-panning,
and so on.
-BYPASSED- - if you choose this item, the filter is removed from the signal path altogether. This setting is
handy if you need to focus on the sound of the other filter while adjusting it, or if you simply find that
just one of Filterstation‘s filters is enough to do the job.
