=== very cool patch challenge edition 26 ===

you are challenged to make a patch in vcv rack to showcase a particular module in a creative way, so other users may get inspired. you can also win eternal fame!

this time the featured module is:

squinky labs gray code

see https://github.com/squinkylabs/SquinkyVCV/blob/master/docs/gray-code.md

== rules ==

  • make a patch in vcv rack using the chosen module and upload your patch to https://patchstorage.com/

  • tag your upload with vcp-26

  • you are encouraged to only use free modules in the patch, but this is not required

  • make a video showcasing your patch and upload it to youtube

  • add a link to your video as a comment to this post (these videos will be collected in a playlist)

  • give feedback on other participants’ patches

deadline: monday end of the day, wherever you are, march 11th

(though late entries will still be added to the playlist)

a new challenge with a different module will be announced every other tuesday.

Here we go:

Stupidly I called the patch “vcp-26” not thinking that it might be a bit generic.
Gray Code is doing 3 things:

  • Controlling the channels of ASAF-8 (it could be controlling the harmonics of Verbo just as easily).
  • Controlling the cv inputs of Plaits and Rings by way of some slew limiting.
  • Determining the pitch through the mix output into Noobhour Customscaler (if you haven’t tried it you should)
    No feedback. No one to feedback into.

nice patch, dag! i really like how you’ve used gray code, and i should look deeper into customscaler.

i do hear some harshness that my ears are sensitive to, which i would put a filter on.

i like the drone under it all, and would probably have made that a bit more prominent.

this is a good start! looking forward to what others will do with this module.

Thanks. I actually made it within about 5 minutes of seeing the challenge and then had to wait until the next day to actually record it.

my entry for the VCP-26

I took 8 gray codes and chained them.
The first is fed by a 60000bpm clock and the last is about 0.5 bpm,
each of them is controlling the clock input of a leakage, which sends pitch to quantums, which are send to basals.
then some unsynced slow lfos for modulations.
A quite simple patch, but I had immediatelly the idea of chaining the gray codes, when I saw the VCP-26 challenge.
I hope some might like it.

the patch is here:


nice result! i never would have thought of doing it this way.

Fantastic idea, and the result is amazing.

I first wanted to do it a bit different, I had the idea to use the first output of the first gray coode for the clock of the second instance of gray code, and then from this one the second output for the clok of the third instance, and from the third instance the third output for the fourth instance and so on.
But that would make it much to slow for the triggers, it would take some days or maybe weeks untill the triggers get to the 8th instance :wink: .
So I used only the first outs, and it needs a really fast clock for the first clock input o get through untill the 8th instance.
anyway gray code is a great module :+1:


thank you

@ dag2099
a great patch, lots of variation just by the right connections :+1:


a nice basic patch imho, maybe you mixed it a bit too hot with some harsh distortion,
I had a little play with it and edited it, I added a quantum and a customscaler for some generative melodics :wink: ,
I hope you don’t mind

On the contrary, thank you for your additions.

Feedback and distortion… are life :slight_smile:

Forgot to ask: what filter would you use and where would you use it? My sound design skills are not what they could be.

filter choice is a personal thing, and i recommend playing around with different ones.

that said, my go to filter (especially for low-pass, which is what i need most of the time) is vult tangents. it simply sounds great, and is low on resource usage.

sometimes i choose another vult filter such as unstabile, and i also like lindenberg research’s valerie ms-20 type filter.

I really enjoyed your patch. The relatively constant drone and much of the piece reminded me of bagpipes…which I happen to like! Now, I have to go explore ASAF-8, Verbo and Customscalar. This VCP challenge is a great way for me to learn more. Thanks for your entry!!

Noobie here and this is my first entry into the challenge. Will say it’s a great opportunity for learning more above VCV Rack. And, it is GREAT FUN!

Reviewing other entries provides many, many learning opportunities. Makes me want to run off and try all those other modules!!!


I closed my eyes and was sitting in a huge, old European cathedral listening to the pipe organ playing. Wonderful patch!! And, very clever!

So cool to finally make it to a VCP challenge. Thank you! Some great patches here.


Dear Rack Colleague,

We are pleased to provide you with the enclosed YouTube link and patch file of “VCP-26 Entry - Gray Code”

Well, thanks for making the modules. I don’t use them as much as I should (though in my defense there is quite a large selection of others to choose from). In fact, i don’t think I’ve ever even tried gray code. I should probably do another patch with more Squinky Labs stuff in it.
