Leonardo Laguna Ruiz Releases Free VultModules For VCV Rack

7

Leonardo Laguna Ruiz has released VultModules, a set of three virtual filter modules for the open-source VCV Rack virtual modular synthesizer.

The free VultModules expansion pack contains three individual filter modules for VCV Rack. One is a state variable filter with low-pass, high-pass, and band-pass outputs, the other one is a ladder filter with 12dB/oct and 24dB/oct outputs, and the third one is a comb filter.

All three modules share a similar design style with a dark gray panel and large black-colored knobs. They look very good inside VCV Rack and fit the rest of the software rather well visually. As for the features, the state variable filter and the ladder filter are both resonant with voltage inputs for the cutoff and resonance. The comb filter comes with tune, resonance, and feedback knobs with voltage inputs.

The filters sound good on all three modules and are a much-needed addition to VCV Rack’s basic filter set. I especially liked the tone of the ladder filter, particularly the 24dB mode which sounds very solid. The variable state filter doesn’t behave smoothly at higher cutoff settings, which is probably a bug that will be fixed in a future update. Pull the cutoff knob from 100% to around 70% and you’ll hear a fair bit of instability and wobbly behavior which, I’m pretty sure, is not intended.

Just like VCV Rack itself, the VultModules expansion pack is open-source meaning that you can download the source code and modify or edit it. Of course, the ready-to-use compiled version can be downloaded completely free of charge from GitHub as well. To add VultModules expansion to your VCV Rack installation, extract the downloaded ZIP archive and move the “VultModules” folder to the “Rack” folder inside the “VCV Rack” directory on your hard drive.

VultModules is available for free download via GitHub (1.47 MB download size, ZIP archive, expansion pack for VCV Rack).

Share it like a boss.

  1. I LOVE that people are actively participating in the development of new VCV rack modules! :D

  2. Andrew Belt says the new version 0.4 is coming this weekend, it will have LFO’s, additional modes for Braids and Tides and stackable cables (more than 1 cable on 1 output). Hopefully the newest version of the Vult modules will appear in compiled form then, together with some more 3rd party modules (they are already there, also with a fix for the filter, but uncompiled, and I never compiled anything).
    A list of available modules can be found on VCV Rack’s Github wiki:

    Hi Tomislav! I’m glad I found this review. I’m Leonardo, the developer of the modules. I have fixed the problem you mention with the state variable filter. You can find the updated versions now for VCVRack 0.4.0.
