Hello,
Source repo here: https://github.com/janne808/kocmoc-rack-modules
and link for the library: https://library.vcvrack.com/kocmoc
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
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:
Revert SVF slug for backwards patch compatibility
Changelog for v1.2.8:
Improve nonlinear integrators for SVF and implement input stage saturation for classic analog filter sound
Changelog for v1.2.9:
New Sallen-Key filter module with trapezoidal diode clipping integration method
Changelog for v1.3.0:
Polyphonic summing for all monophonic filters
Antisaturator diode clipping implementation for SVF (heavily inspired by Vadim Zavalishin’s VA Filter Design book)
Phase Modulation OP is now polyphonic and has phase reset input for hard sync and an overall phase offset parameter
Changelog for v1.3.2:
TRG now has a menu option for following the active step and manual page selection button
Built-in attenuverters for all the filter modules’ control voltage inputs (SVF, LADR and SKF) for smoother patching
Changelog for v1.3.3:
Full polyphony for all filter modules (SVF, SKF and 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.

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.

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.

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.
