Kocmoc modules version 1.2.1 released


Made my first Rack module, an interesting take on the state variable filter – giving it a bit of an analog Moog slap.

Source repo here: https://github.com/janne808/kocmoc-rack-modules

Proper release later I suppose, I think it needs a bit more work to configure the oversampling from the context menu and other stuff before that.

Criticism and hacks are welcome.

Changelog for v1.0.1:

  • Separate inputs for linear and exponential control voltage
  • Context menu items for choosing the oversampling factor

Changelog for v1.1.0:

  • Minor tweaks for SVF-1
  • Add Roland TR style minimal trigger sequencer TRG

Changelog for v1.1.2:

  • 6 HP redesign for SVF-1
  • SVF-1 context menu for choosing the integration method (Euler, Predictor-Corrector and Trapezoidal)

Changelog for v1.2.0:

  • Fix TRG resetting
  • Normalize SVF-1 gain for high input driving
  • Add new Moog 4-pole ladder filter module LADR

Changelog for v1.2.1:

  • Add implicit integrator method (so-called zero delay feedback integration method) for LADR

two pole state variable with tanh distortion between the stages? ok.

cann you provide a compiled win version to test it?

I don’t have a build environment set up on Windows at the moment, so I can’t test or provide a compiled DLL.

Thank You very much!

Version 1.0.1 is now available on the Rack library for anyone interested.

Hello all,

I needed a small simple Roland TR style trigger sequencer module but couldn’t find one. It was time to fix this and make one myself.

The result is a minimal trigger sequencer called TRG with support for up to 32 steps using a custom NanoVG widget interface with the classic Roland chase light style buttons. I hope you find it useful.

I’m not comfortable with pushing it to the Rack library yet, since there could be some bugs but feel free to try it from the repo for now.


Mac version?

I uploaded the binaries under github:





Version 1.1.2 is now released and downloadable from the library.

New version 1.2.0 released with a new filter module LADR which models the classic 4-pole Moog ladder filter featuring lowpass, bandpass and highpass outputs.

Here are the prerelease binaries:




Stay tuned!


Version 1.2.1 is now available on the Rack library.

This version includes a new zero delay feedback integration method (called “trapezoidal” in the context menu) for the LADR filter.

You can now check for yourself how much of a marketing weasel term it really is in terms of synth audio filters. :wink:


Introducing a new minimal phase modulation operator module OP:

Currently in testing phase on the repo as source, prerelease binaries and Library release later.
