Mixing Techniques for Eurorack & Beyond! // Cosmix Pro from Cosmotronic

In this video I’ll be exploring Eurorack (and any format hard/software) mixing techniques alongside the Cosmotronic Cosmix Pro. I’ll be going through 5 patches showing mixing basics while pushing things further with setting up auxiliary parallel processing, feedback loops, how to “hack” CV control, feedback distortion and more.
I’d love to hear what you think of the patches in the video and the general pace. I took more time than usual to go through each patch - is the more relaxed pace helpful? Or would you prefer more patches in the video?

I really appreciate how you've formatted some of these newer videos like this and the eas video to apply more broadly to mixing, logic etc. Love your content and thankful for what you do

[@mrotaveria]

simple and really well thought out mixer, loving it!

[@pixelfrenzy]

Loved the wonky bit at the end! Feedback and mixers is always interesting... would be great to see some more techniques like this, especially around what's used in dub.

[@DivKid]

Hi Chris, thanks for pointing that out, I love the wonky sploppiness of it. I agree with the feedback stuff, something to think about for future things but I'll continue to put these things in other videos too.

[@stopinterview]

Awesome as always Ben!

[@DivKid]

thank you, appreciate that

[@Paul-js9eq]

Another brilliant video, you show the Cosmix Pro really well plus give lots of food for thought. This has answered several questions I have had for a long time now. Thank you. This works really well A+++++

[@DivKid]

Thanks Paul, glad it was helpful and I appreciate the comment.

[@Fiidsey]

Lovely timing. I have one of these arriving today. Thanks!

[@DivKid]

HI Jay, hope you're enjoying it.

[@bengineer_the]

Thank you ever so much for the inspiration there! Just made an awesome feedback loop from one channel of micro-clouds back in on the other 😍 wow!

[@DivKid]

Happy to be, thank you! And cool, stereo modules with one out to the other make feedback simple. Now if you patch the output to a VCA, then VCA out to the other input you can CV control the feedback to have a CV controlled feedback - really nice!

[@bengineer_the]

@@DivKid Now there's a shout - thank you again :D

[@WRXcellent]

Nice to see the Three Body in your system. I would absolutely LOVE a video on that one.

[@tracyharms3548]

I’m confident it’ll be happening soon enough. Eager as I am to hear Ben demo Three Body, the more he takes his time the more scrumptious it will be!

[@dualtrx]

Great video ben. i love this format of an eurorack mixer. It has any thing it needs a mixer. This was something needed. Some serious competition for the WMD Performance Mixer.

[@DivKid]

I've been enjoying it, it's a tricky thing to "get right" as there simply is no "right" in terms of the feature set for something. But I like options both in the module choices and the modules themselves and this one has definitely been fun to work with so far, good work from them.

[@brentgreeff1115]

Awesome video. As someone who has never used Eurorack but has a lot of experience DJing and a bit of Ableton - the line level setup looks amazing. - I would love to have 12 tracks, and other FX - for instance the Chorus 6. - and be able to send each channel like a DJ mixer. Would be great to see more on this.

[@alchemist.D]

Great job man 😊

[@DivKid]

thanks

[@GeorgeLocke]

Reverb feedback makes the best drones. You gotta be careful, but when it's right, it's wonderful.

[@DivKid]

absolutely, even for less obvious "feedback" just having some feedback to extend the length of reverbs and add into delays is always handy.

[@BogdanRaczynskiMusic]

nice, thanks

[@DivKid]

Cheers Bogdan

[@jasoneskridge6453]

just got mine last week but need to record current patches before majorly reorg'ing my system to add it. very much looking forward to replacing my trusty STMIX with Cosmix Pro, but also reusing STMIX as the aux return mixer feeding Cosmix. i can see how that will help with some of the feedback patching you suggested here.

[@DivKid]

Good call on using the ST Mix as a mixer for the stereo return on the Cosmix Pro. It's good to remember (why I did in the last patch) aux sends don't have to return into returns (into channels is fun, on other mixers that means you can then EQ your FX return too on the channel) and that return inputs are just inputs (often without level controls). So they can just be for extra audio.

[@jasonkelly4885]

Cosmotronic, Great job on this!🎉

[@DivKid]

Yeah nice work from them.

[@hyderhydra3269]

that PRO workout!@!!

[@DivKid]

what about it?

[@hyderhydra3269]

@@DivKid i like it alot wish i didnt get the older version right before the PRO was released, that bigger screen is really nice looking

[@woundsdrone]

Great video. Been using this module a lot lately love the CV Aux Send idea. Question that I’m sure you get a lot, but how do you keep your Eurorack output so clean?

[@DivKid]

thanks! In terms of keeping it clean, I really do very little to nothing to the audio out of the system. I figure I'm demoing the patches and system, not a cleaned up or mastered version. So my output just goes as two tracks for stereo into a relative cheap interface and I record it into Logic. I don't add plugs or processing to the modular audio. I do adjust the overall level of each track and at the final audio editing stage I duck/sidechain the modular audio against my voice and then just level out the mix of the voice and modular to hit streaming standards. So I've no real answer/help there in terms of "clean" other than it's just left open and as is and made simple.

[@rdean150]

The only feature i wish this had was a way to get post-fader outs for each channel, to allow for multitracking while also capturing the full stereo mix. AFAIK the only euro mixer that can do this is Praga, but there are several other things it lacks vs the Cosmix Pro. Even the WMD PM only has pre-fade channel outs, and even that requires an expander that's unobtanium these days. All told though, this looks and sounds like a fantastic mixer. Great size for what it's capable of, too.

[@DivKid]

HexMix on the HexPander has direct post fader outs, I use that combo with an 8 way snake to track things sometimes. Also the manual shows some direct out points on the back of the PCB, so it _might_ be possible. I'd have to go read the manual again and also ask what was possible.

[@rdean150]

@@DivKid Oh snap, I didn't know that about the HexMix. Thanks for the info!

[@DivKid]

well worth a look, all that aux control and the direct post fader channel outs is nice. HexVCA gives you level controls over it all on the way in too.

[@Eightball69]

I've currently got the Mega Tang but this has caught me eye. Should I get this?! 🤔😂

[@DivKid]

I can't make that decision for you, try out some of these patches with the Mega Tang and see how you like it. It's all broadly applicable to other modules (expect may be aux send hack). Mega Tang looks good, but I haven't tried one. I am enjoying the Cosmix Pro though and I've continued to get good patches out of it.

[@user-cl3wy2mp4i]

Can you for example output only wet for one of the voices? Or does it always get mixed with the dry signal?

[@DivKid]

I don't quiet understanding, do you mean with the auxiliary sends?

[@patrickdowling6442]

Heh, that reminds me once again of the lack of useful things like mixers in my setup (which admittedly often looks a lot like that pile on the left there). Maybe I should just buy one instead of DIY...

[@stashusclay]

The lack of a headphone jack output is really disappointing. Not a deal breaker but disappointing.

[@DivKid]

it could be a future expander, the ALM HPO is a nice 2hp option for a quick headphone out on a system if needed.
