So I have been building this thing for over a year now and thought I would start a thread and see what the DIY community thinks of the project.

It is what I call (for lack of a better term) a "4-channel Voltage Generator / Quantizer" seriously, i just don't get it

Here is a vid of my friend using the thing https://www.instagram.com/p/BtwLhoBhjfV/?utm_source=ig_web_copy_link

Here is a vid of me using the thing:






For a more detailed description of the project checkout the github repo https://github.com/scottc11/modular/tree/master/degree, otherwise read on!

Basically it is a quantizer that has the additional option of just outputting a specific quantized voltage, bypassing the whole CV quantization step. So far it has been great for creating 4 voice chords/harmonies via 4 individual oscillators. It has completely removed my need for a MIDI keyboard in my setup, which is cool, because a modular ain't no piano.
. I attempted using a CVPal at one point, but even that left me frustrated as I had to work in the DAW which is a huge no-no for me. I mine as well just use VSTs at that point.


Each channel has the following hardware:
- CV input
- GATE output
- 1V/octave quantized CV output
- 8 touch sensitive buttons with LEDs indicating which scale degrees are active / inactive
- Pornomento / glide analog circuit via slide pots
- octave up/down switch (4 octaves total)
- "mode" switch for toggling between what I call `monophonic` mode and `quantizer` mode


There are actually an additional two touch buttons that I haven't programmed any software for yet - lots of things I could do within the code but haven't felt a dire need for anything yet.

A lot of people have asked what the touch things are, and its quite simple. You just take a 5mm or 3mm LED and cram it into a Thonkiconn Jack. The Sleeve of the jack acts as the conductor for capacitive touch. If there was a part out there on mouser/digikey to simulate this hack I would likely use it, but until I find that part this seems to be the cheapest option... and it ended up looking pretty cool so I might just keep it like this

Very very cool!!!!!!

Those jack buttons look super responsive to play - really cool! Is it easy, getting them to play nicely with the capacitative touch IC?

surprisingly very easy. There is some kind of auto-calibration going on in the IC so it is essentially plug and play. You obviously have to make sure your code doesn't lag when a touch event happens, but I honestly have yet to experience any problems. The microcontroller I am using is capable of doing 1 million operations per second! crazy.

+ 1.

I recently read Pinch and Trocco's book on the history of the Moog, and this issue of whether synths should have keyboards or not was fundamental in the fortunes of Buchla vs Moog.

It's cool that after about 40 years of keyboard dominance, the modular comeback is mixing things up.

I have no idea how it works but this quantizer looks awesome, great project!

Interesting. I'd build one.

Hello, interesting beast.

Cool to share your soft. I didn't find the appropriated schematics.
Could you please tell me where to find them?
windspirit
Looks really cool, would be interested in building one.
ESSY
@alain6870 I'm pushing all the code to this repo https://github.com/scottc11/modular/tree/master/degree. I will definitely try and get a solid version of the schematic up soon!
petkost
Really cool !!

Very cool! I’d build one!

I would be down to do a small PCB run for people interested. Though, I have never done a group by before. How does that all usually work?

Also keep in mind that you are going to need ALOT of thonkiconn jacks ahah.

I would probably use a Google sheet to track listed usernames and who has paid vs not and shipped vs not

Wow, yeah I would definitely be up for a pcb. It's a really inventive interface, and exactly the kind of thing I'd love to play with. The O_C is brilliant, but a bit 'menu-divey' for me.

I have yet to build / use an Ornament and Crimes - on my to do list. But ya, I feel the same way about menus which is why I have avoided modules like that. That being said, I do have like a million switches on this thing... ahah

Brilliant! Where would we be without Google
