  • 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

Changelog for v1.2.5:

  • Rename SVF-1 to SVF
  • Implement new tanh-limited integration methods for the filters (SVF, LADR) for a fatter analog sound
  • New basic phase-modulation modules: OP and PHASR
  • New utility module MUL for multiplying signals together

Changelog for v1.2.6:

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.

Gracie!

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:

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.

Pushed some new code in the repo (https://github.com/janne808/kocmoc-rack-modules) for the filters (SVF, LADR) to handle nonlinear limiting in a different way, result is a more loose fat analog sound. Test it out if you want and know how to compile.

Proper library release soon.

Stay tuned.
