I’m happy to announce that the first batch of Steve’s MS-22’s (PCB/panels and assembled modules) has completely sold out in about one month. Here’s a big thanks to all of my customers for making that happen! :)

So, what’s next you may wonder? Here’s a list of what I have planned in the coming weeks and months:

• There will be a next batch of MS-22’s somewhere near the end of march, so please keep an eye out for that :).
• Two more demo videos will accompany the next batch.

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).… Read more

As the rev. 2 prototype of Steve’s MS-22 is nearing its final form, I am happy to release its specifications :

• General features
  • Dual VCF inspired by the Korg MS-20 OTA filter
  • Low-pass into high-pass configuration
  • Innovative modulation matrix allows CV control over all parameters
  • Cut-off frequencies can be linked, resulting in a band pass filter with controlable bandwidth
  • Bipolar monitoring LEDS for the LP, HP, resonance and gain CV signals
  • One of the best functionality-to-size ratios in Eurorack with a width of 4 HP and a depth of 45 mm
• Connections
  • Filter input
  • Filter output
  • Frequency CV input (FCV)
  • Auxiliary CV input (ACV)
• Controls
  • LP cut-off frequency (“frequency”)
  • HP cut-off frequency / BP bandwidth (“spread”)
  • Resonance : from mild to screamy
  • Gain : from warm to asymmetrical saturation
  • LP Frequency CV (FCV) attenuator
  • Auxiliary CV (ACV) attenuator
  • LP-HP link switch : 0%, 50% or 100%
  • Modulation Matrix switches, routing ACV to HP cut-off / spread, Gain and resonance : +ACV, off, or -ACV (inverted)
  • Calibration trimmers for the HP and LP filter are available from the side of the module.

As a follow-up to my previous post I will show how to convert the sample pack of Music Thing’s Radio Music so it can be used with the Erica Sample drum (or any other sampler). You can find the download link for the converted sample pack at the bottom of the post :)

In this post, I will show you how to do a batch conversion of whole sample packs (e.g from MusicRadar) into the right format for the Erica Sample Drum by combining Sox and shell scripting.

I have received new and revised prototype PCB’s for Steve’s MS-22. Next week, I am planning to assemble these in between going to see Gregory Porter at Gent Jazz and Neil Young at the Sportpaleis in Antwerp (good times ahead!). In addition to the PCB’s, I also had new front panels manufactured in a sleek matte black finish. In the picture below you can get an impression of what the final product will look like. Stay tuned!
