Filter Module Comparison Table August 22.

Filter Types normally refers to high, low and bandpass but a couple of modules offer more.

An attenuator controlled input means there is a knob on the module to control the level of that input.

Key.

• $ = See below.
• A = Almost, but not self resonant.
• N = little/no self resonance
• Y = Will self resonate.

There should also be a honourable mention to the Dead Band module, by Keurslager Kurt. This could be considered a notch filter, but you look at the Wiki page and decide for yourself.....

Dead Band

Notes

• The MS20 Filter is excellent for Kick/bass drum sounds, toms etc. Turn the resonance up!
• The Nyle (Steiner type) Filter is the only AE filter with a CV input for resonance level. It also can mix up to 3 different filters on one output.
• The State Variable Filter has 3 outs for the low and bandpass filters, and 2 for the highpass filter. It also has excellent self resonance.
• The Wasp Filter has 3 outs for the low and bandpass filters, and 2 for the highpass filter. It is a characterful filter.
• The Diode Filter is obviously great for TB303 impressions/baselines etc. Two of the CV ins are for "Accent", i.e. lift cutoff freq &/or volume.
• The Kuzmin Filter is the most characterful AE filter, and can be really grungy/dirty. It has a built in distortion circuit you can turn on/off. It also has Frequency Modulation of the cutoff point (on/off via a switch), and another switch which can make the resonance "hard" or "soft".
