Hi all!
I have a new module to present you: The Great Divide!
Store page: www.tindie.com/products/keurslagerkurt/the-great-divide-2-x-r2r-module/
Before I dive into what it is exactly, first some small remarks:
- This is a (very) small first batch, as these are leftovers of the prototype run. The next run should arrive in a few weeks, and then the module will be restocked on the website.
- The Dead Band is, sadly, still out of stock due to problems at customs. My last components have been stuck in customs for more than a month know, even though I did already pay the import duties and they said it would be cleared in less than a week..
- The upcoming Sloth module is working perfectly as a prototype, but I made a mistake with the frontpanel. So this module should go live in a few weeks as well when the new boards arrive. Final permission from Non-linear Circuits is also granted for the AE version
- Five Steps prototype is almost finished, but I need some of these 'stuck' components to test the latest prototype... But this one should be live before the end of the year as well.
Now back to the new module!
It's a very simple, but suprisingly fun & useful module. Some more info about it, that is also on the Tindie page:
The Great Divide is a passive mixer, CV manipulator, Digital-to-Analog converter and more. All at once, and pretty experimental in every of those aspects! And it's actually twice this circuit!
The Great Divide is a module based on, probably the first ever, Digital-to-analog converter circuit: the humble resistor ladder (also known as R2R). Comprehensive Wikipedia & textbook pages have been written about this barebones, but useful circuit.
The genius idea to implant this primitive circuit into modular synthesis, does not belong to me, but to the fantastic Olegtron. They also have a great, comprehensive article on how a resistor ladder can be used in music: www.olegtron.com/olegtron-r2r-1 . I highly suggest reading their webpage to get inspiration for how to use this type of circuit in a musical setting.
The Great Divide is specifically tailored for the AE Modular format. The resistor values have been changed, as well as two outputs/inputs that have been dropped. But in return, you get TWO resistor ladders in one module! Basically a 2R2R! The eight left AND right patch sockets each contain one resistor ladder. Each of this sockets can be used as an input, or an output, its really all up to your choosing. There is no danger to create shorts of any kind, as the resistance between each socket is high enough to guarantee free patching. So don't stress, and just try stuff out.
In order to fit two circuits under one hood, I had to drop one input in each of both. For the left resistor ladder, the '128' input has been dropped. (Meaning that, from a traditional R2R viewpoint, you basically have 128 possible bits instead of 256.) For the second circuit, the '1' input has been dropped.

For the next run, I'll be adjusting the BOM and the components shipped. (Btw, the second divider at the right is correct, lucky me I put two in there haha)
