Steve’s MS-22 Eurorack Filter

The MS-22 is a dual voltage controlled filter, inspired by the classic Korg MS-20 filter, with an innovative modulation matrix and one of the highest function-to-hp ratios in the land of Eurorack. This module was inspired by many pleasant chats with tech journalist Steve O’Hear.

What makes the MS-22 unique

The MS-22 contains two dedicated filter circuits, one low-pass and the other a high-pass. These are configured in series, the low-pass going into the high-pass. This configuration allows for a unique duophonic fighting resonance behaviour (see the demo video below). The cutoff frequencies of both filters can be CV’ed. Compared to most bread-and-butter MS-20 clones, the MS-22 is twice the amount of filter condensed down into half the package (4HP).

Furthermore, the MS-22 also possesses the following selling points :

  • The MS-22 offers CV control over input gain, basically, this allows you to either CV the level of filter overdrive or use it as A VCA for the signal going into the filter
  • The MS-22 offers CV control over resonance, the MS-22’s resonance can also be pushed way further compared to Korg’s MS-20
  • The MS-22 has a link switch, which links the cutoff frequencies of the low-pass and high-pass filters in two different ratios. This creates two flavors of band-pass filters, of which the bandwidth can be tweaked and CV’ed. The switch itself also serves as an awesome performance effect as you can use it to create an instant drop. I demonstrate this near the end of this video.
  • The MS-22 has a unique modulation matrix that allows configuring many internal patches without using cables. The modulation matrix is designed to encourage happy accidents!
