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.
| Model | Cost (march 2022) | Rack Space | Inputs | Outputs | Available Filter Types | Simultaneous Filter Types | Self Resonance | Attenuator Controlled Inputs | Other CV in | Wiki Page |
|---|---|---|---|---|---|---|---|---|---|---|
| MS20 | €35.00 | 1 | 2 | 3 | 2 | 1 | Y | 1 | 1 | MS20 Filter |
| Nyle | €47.00 | 2 | 1 | 3 | 3 | 3 | A | 2 | 1 | Nyle Filter |
| State Variable | €32.00 | 1 | 2 | 8$ | 3 | 3 | Y | 1 | 1 | State Variable Filter |
| Wasp | €33.00 | 1 | 2 | 8$ | 3 | 3 | A | 1 | 1 | Wasp Filter |
| Diode | €36.00 | 1 | 2 | 3 | 1 | 1 | N | 1 | 1 | Diode Filter |
| Grunge* | €43.00 | 1 | 2 | 3 | 2 | 1 | N | 1 | 1 | Grunge Filter |
- The grunge filter was previously named the Kuzmin filter
- $ = 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.....
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 Grunge 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".
