Today, ThreeTom Modular is releasing the “Steve’s MS-22 dual VCF” module for eurorack.
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.
The MS-22 contains two dedicated filter circuits, one low-pass and the other a high-pass. These are configured in series, the high-pass going into the low-pass. This configuration allows 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 has the following unique selling points :
- The MS-22 has a unique modulation matrix that allows to configure many internal patches without using cables. Simply put, the modulation matrix (12-14) lets you route whatever modulation source you have connected to the ACV (auxiliary) input (e.g. an external envelope, LFO, S&H etc) to any or all of the following: HPF cutoff frequency, resonance amount, and input gain amount, either inverted or not
- The MS-22 has a unique link switch, which links the cutoff frequencies of the low-pass and high-pass filters in two different ratios. This creates two flavours 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.
Steve’s MS-22 is built to order in limited batches, the current batch consists of 10 units. Fully assembled modules are available for 225 EUR (excl. shipping). A limited number of DIY PCB+panel sets are available for 50 EUR (incl. shipping).
More information (videos, specs, manual) can be found on the product page. Orders can be placed over e-mail, as described here.
