Venom Modules - Beta release home stretch - submitted to library

I believe most stereo modules treat a single input on the left with none on the right as mono. Essentially you just use the left port for in & out if you don’t need stereo. Does this make sense?


Here is a post showing what I see with other VCOs that do true through 0 FM with a 0 Hz carrier wave:

I like your Med Light Version a lot , which is strange as I always normally go for the dark … this one should be an option for sure . Cheers .

Ooh, always wanted to try out the VRR.

Please do tell me about your experience with Rhythm Explorer if you do try the beta. Do read the documentation I have written. There are definitely major similarities with Vermona’s Random Rhythm, but a lot of differences as well.


  • No swing for 1/16 notes (well maybe you could achieve something similar with the external clock, but haven’t tried)
  • No internal clock - requires 24 ppqn external clock
  • No dual rhythm generators, just the one


  • Addition of XOR odd parity and XOR 1 hot to go along with the OR output
  • Linear mode to go along with Offbeat mode
  • Ability to turn off Offbeat (and Linear) for the OR output, which is where XOR becomes interesting
  • More simultaneous divisions for one generator, 8 instead of 4.
  • More division options 1/2 - 1/32, as well as triplet versions of each
  • Each division channel division value can be individually assigned, including repeated division values
  • The order of the divisions is important when Linear or Offbeat is enabled
  • Linear / Offbeat / All can be individually assigned to each division channel, even for the OR mode if using poly CV control
  • Ability to capture the pattern seed value, as well as seed value input so patterns can be captured and played back later
  • Ability to provide your own “random” input to achieve totally different patterns than you get with the internal pseudo random number generator
  • More meter options - bar length up to 16, and phrase length (bar count per phrase) up to 16
  • Addition of clock division outputs, as well as bar start and phrase start trigger outputs
  • Individual division channel mutes to go along with global mute
  • Lots more CV inputs
  • Reset trigger and Run gate outputs to go along with inputs

A good use case for my Bernoulli Switch recently came up in the forum.

And here is my solution using Bernoulli Switch along with a couple modules from Count Modula

Venom Modules Beta 2 is now available at VenomModules/ at main · DaveBenham/VenomModules · GitHub

The biggest change is the added support for themes - there are 4 to choose from:


I have also added RECURSE STEREO - a stereo version of the RECURSE module.


Technically the original RECURSE module is no longer needed, the stereo version is perfectly happy processing one input and output using the Left channel only. The stereo version uses a tad more CPU, but I think it is inconsequential. I also think the stereo version may be a bit more confusing if you don’t use the stereo capability. I’m curious, what do others think? Should I keep both versions? Or should I just have the stereo version and rename it to RECURSE?

I’ve also enhanced the behavior of the Rhythm Explorer Mode buttons and CV input. The CV now updates the displayed value in the buttons to give you visual feedback. I also fixed some bugs in Rhythm Explorer.

Now that the themes are in place, I hope I can get some feedback as to the functionality of the modules. Which ones have you tried? Are they useful? Are they working properly? Is the documentation clear? Or any other feedback is welcome.

Unless I get reports of some bugs or significant design flaws, I think I am almost ready to submit the plugin to the library.


Just keep the stereo version and rename it. As long as you’re in beta there’s no need to keep obsolete modules around.


Thanks - I absolutely agree. I was/am inclined to remove the original version. It’s just that I have seen a number of plugins with similarly redundant modules, perhaps because the “redundant” module was introduced in a later version, so you wouldn’t want to remove the old form.

But I was/am just curious if there is anyone that would prefer to have both.

I prefer to have both single and dual. Helps reduce clutter, increase productivity / focus I think, to only see the channels I use. If the load is reduced using the mono version, I’ll accept that as a bonus.

Thank you for creating these modules, and making them available free-of-charge and open source to learn from.

It still builds on Chromebook Linux VenomModules-2.0.beta2-lin-arm64.vcvplugin - Google Drive

Thanks. I may keep both on just your recommendation. But if someone else also indicates they prefer both, then that will settle it for me.

Please keep both… Less clutter is a good thing when patching … Thanks for the plugins!

I especially like ivory and earth, particularly in ivory the Venom logo really pops :slight_smile: And the red on metal has a clean intellijel look to it.

Nice modules :slight_smile: about colors, Many great devs 'painting" theirs face plate to create a brand image, but as seen on the two examples below (both using pretty much the same colors just in a different way) sometimes you just need small touch at the right place to have something that stands out but still being well balanced in a larger thing :smiley:
I really like the Coal and Ivory version for these reasons.

We make “plugins” that are part of a big rack over which we have no control, so I guess if one wants to stand out by being colorful, it’s cool but we have reconcile this with the fact that we are only making small bits of a bigger think that is not ours


I like the way these modules are pretty dense, but still usable. A couple of things seem non ideal to me:

  1. The jacks have the labels on top, but the knobs have the labels on the bottom.

  2. The font used seems to be a bold all-caps font? Seems a little less nice that other modules. Of course many modules use fonts that are very small.

  3. I don’t think Venom Classic should be the default theme. Most ppl will find this quite ugly (imao). Having watched discussions online a lot, I think your default should be one of the dark themes. Some ppl hate light themes, very few ppl hate dark ones.

haha - this is like one of those games - spot the bad visual design elements. Aside from the obvious crooked color patchwork, it also has:

  1. Mixing light and dark background means you need to mix black and white text to make it legible.

  2. But even here there is illegible black text on a dark background.

  3. The font is super low resolution.

  4. The font outline itself is not very legible at small sizes.

  5. This is probably an official rule if you go to design school, but it is very, very difficult to use more than two colors in a design.

Whereas I con understand these discussions regarding panel aesthetics, one of the cool things about the Eurorack “standard” is that there is no appearance aesthetic standard. Seems to me that it should always be up to the developer to define their own personal aesthetic. But then, some users will choose to use some modules and others will choose not to, based on their personal aesthetics.
