Superb! Many thanks to all.

I really like the string machine, but I’m not imagining a great way of sending polyphonic CV to it. If we’re breaking with Eurorack convention already, I wonder if I can just use ribbon cable to send polyphonic CV…

If MIDI is involved I’d keep it MIDI. But the string keyboard matrix may give you a cv entry point.
There are £5 MIDI file players out there you could trigger with cv.
So I made this VCV Rack module that I’d like to implement as a a Kosmo hardware module at some point:
but then that’s 8 connectors just to get 4 notes out of the string machine… with all these ribbon connectors and cables, I could get 12… Hmmm… we’ll see where this goes.

Take a look at some of the logic chips out there and some of the work Sam did recently. Pretty sure you could block up a chord in cv

I’ll take a look, cheers. My goal with getting into hardware was kind of to avoid doing more software since that’s my job, but with the abundance of cheap Arduino Nano clones now (and the Daisy Seed for heavier stuff), lots of stuff I want to do will now be a lot easier in embedded software. But then is that as much fun? Shrug. More fun to try weird stuff.

I find im in a similar boat, but hey if you got the skills why not right?

Right now I’m in the “working code there so just load it” camp. It’s no different from a mutable instruments build.

I think you could repurpose the analogue patching concept for domains broader than just mono control and audio. There are many ways to take that basic idea and end up with something usable. Most of those notions have probably already appeared in digital music composition languages such as SuperCollider and the like, and then you have the DAWs which grew out of studio mixing technologies and specialise in massive multitracking and complex automation.
Somewhere there’s a sweet spot where you can sit with a surface and some knobs and faders and patch cables (or pin matrices) and compose music using a modular approach. It shouldn’t involve ribbon cables and other monstrosities. A relatively simple way to implement a very broad patch-based system would be to make the patch cords into one-way serial cables (single core perhaps) carrying OSC messages.

Love your approach mate. Looking forward to your new project. Have fun with the neutron. When I was raving to my youngest about my new neutron he replied “3340? But haven’t you got one already?”

That’s me, six unfinished projects a month.

I know that feeling:
There are at least 11 unfinished projects in this photo. And 2 more hiding behind the synth

Just built the Mini Pops last night and it is amazing. Being able to get the blend of patterns with the pot reminds me of when I was a kid pushing 2 rhythm buttons at once on my organ.
I am trying to work out how to add a clock in. I feel like it should be quite simple, but this is my first Arduino project so its a bit overwhelming. Any ideas?
EDIT: my inital thought was attaching a jack in to A5, but I assume this may get convoluted with the tempo pot aswell and make the tempo go crazy.

There is a clock ‘out’ on pin 13 that’s also in the code. The problem with the clock in is the tempo pot. But of this is for a module you could look at the code for this pot.

I find this (sorry all in french) for that the Minipop trigger the modular
but i think the best will be to trigger the Mini pop by modular

Do you have the schematic for the delay you used? I’m looking for a simple delay for my case.
Stripboard…yes, Schematic…no. It’s just the LMNC stripboard single 2399 you can find on this page

My version of the stripboard layout adds a eurorack power connector and puts all the I/O in one place so it’s easy to wire with pins: https://github.com/jhitesma/Modular-Synth-Build/tree/main/simple_delay
