Modal Electronics has announced Filton, a 20HP Dual Analogue Transistor Ladder Filter Module for Eurorack. They say that it is based on the most popular classic filter design in synth history. They did actually design a set of Eurorack modules a fgew years back, but they never made it into production. We note that this module is named after and area of Bristol actually called Filton (its where there is a small airport, and Concorde was co developed back in the day).
Here's the details in their own words...
Filton delivers the distinctive saturated transistor overdrive, resonant harmonic peaks and warm analogue timbres that is adored by many synth lovers for generations. In our acclaimed 002 synth we introduced the concept of polesweeping into the circuitry to allow seamless filter morphing from four pole through bandpass to one pole 6db per octave, or anywhere in between.
Since then, we were asked by many to release the 002 filter as a separate product to use with external sound sources or in Eurorack setups. Filton is our answer to these passionate musicians and producers.
Although the ladder filter within Filton incorporates the same filter circuitry from the 002 synthesiser, Modal made many alterations to the original design to improve both stability and sound. Also, this module contains two discrete filters rather than just one, to process two sound signals independently or allow for series or parallel processing of a single source.
Each filter features an audio input, four analogue CVs with attenuvertor controls for FM, Resonance, Morph and Level, pitch tracking provided by the 1V/Oct input, an audio output and a mixed output. All CV inputs on Filter A have been normalled to Filter B, meaning any CV signal plugged into Filter A is automatically sent to Filter B if nothing is plugged into the corresponding input.
Pricing and Availability:
Filton will be available as a limited Kickstarter edition from 7th September 2022. Modal has no plans to distribute it using its usual distribution network. Various pledge models are available, whereas a single Filton module will be at £299.
