What is "Voltage sorting"? What can we do with it? Let's find out with Midcentury Modular's "Strata"

Come along as I look at a module from a new manufacturer, "Midcentury Modular" (www.midcentury-...). Strata does some interesting things to input signals, effectively "sorting" them, moment by moment and outputing the high, middle, and low ones separately. That opens a couple fun doors -- so let's go walk through them together.

I found out about this module - and this video! - only a few days after building my own stripboard copy of the old Mutable Instruments module "Kinks", where the binary input section is essentially the same as the Max and Min here. Odd coincidence. Thank you for describing what's going on so well! (The first section of "Kinks", the unary input section, outputs the inverse and the half- and full-wave rectified versions of the input, so yeah.) (I just ordered MM's "Dividers" PCB/panel set as well, so that'll be a fun build.)

Thanks for a great video - this is probably the best explaination of analog logic that I have seen sofar. Keep up the good work and you will be hitting 10k in notime. Cheers from Sweden.

Thanks!

I wondered if you would end up picking up one of Midcentury's modules. 😊

[@SoundVoltage]

How could I not?!

[@tcrist56]

WOW! Fantastic. So well done.

[@tcrist56]

Isn't AND -> MIN and OR -> MAX kzbin.info/www/bejne/mITJgX-PabWFmpIsi=cu-GKMj3VLPpWMRX&t=383

[@SoundVoltage]

Damn it! You know how many times I looked at those slides. Sigh.

[@tcrist56]

@@SoundVoltage Still a great video. Enjoyed it a lot!

[@buzzkett]

I didn't get a sense of what happens to multiple audios through it

[@kellymerrill5294]

I'm building one now, what value did you use for resistors? Looks like the 33k is what's connected to them, yet 1 resistor for two LEDs? A bit confused

[@SoundVoltage]

On the 'A' board there are 3 33k resistors (R5 R14 R25), and I went down to 3.3 K Ohms each. How are you enjoying the build?

[@kellymerrill5294]

@@SoundVoltageIt's easy! Nice break from smd. Thanks, I was gonna go with something much lower like 3-5k

Halfway through the video, I‘m still saying to myself „wait, that‘s exactly the same as NSI‘s Babel!“ - then seeing the normalization and reacting „ah. Ok.“ 😄

[@SoundVoltage]

Oh! I didn't know Babel, that's quite interesting!

[@ThMntnst]

@@SoundVoltage I have it plus one 7 Input-Expander. - Loving it, since it adds some operations that have become quite rare in the Eurorack market. In essence, these two modules seem to have the same core-concept and then looked for their unique additions.

Saves a bit of HP, too!

Good yob mane.
