The CMIX is a 6 channel mixer for LZX format video signals.>>>> It is used for mixing several sources into complex patterns and shapes.>>>> The normal channels add signals together, the inverted channels subtract signals.>>>> The 2nd output allows for (example) a feedback routing option to add complexity and detail.

This (open source) module is based on the Simple video mixer schematic by .L.Larsen

project thread:

Ok. I had a layout based on the LZX / L.Larsen design of the Summing mixer. > The basic design of the Summing mixer already has a place in my custom video synth, but > I want to add some features, and make it suitable for the Eurorack format > Maybe a simple filter . I don’t know yet. I was looking at an Allpass filter for phase shifting and possible interesting feedback effect… > Suggestions are welcome! > current layout & schematic features: > 4 channel mixer > 3 normal inputs with attenuators > 1 inv…>

my internet is out for a few days, typing this in a cafe.

I’ll send the payed packages asap (today or monday)

and contact the other interested people soon.

#19 — Robbertunist · 2020-10-03

Hopefully you’ll be back online at home really soon & the disruption won’t have caused you any major hassel

#20 — bentoncbainbridge · 2020-10-04

I’m in for at least one finished module, shipped with tracking to USA. If three finished modules are still available, I’ll take 'em, thanks!

#21 — dr_how · 2020-10-04

I would be interested in a kit if there is one left, shipping to the United States. Thanks!

#22 — reverselandfill · 2020-10-04

There are 2 sets left.

I can reserve 3 modules for you in the next batch, if you are OK with that.

I ordered a new batch today.

#23 — gosseyn · 2020-10-04

#24 — bentoncbainbridge · 2020-10-04

Ok please let me know when the next batch is ready! Thanks

#25 — reverselandfill · 2020-10-04

I will! the factory is pretty quick, so I expect they are here in a week or a few days more

I have a lot of packages ready to ship, so I will be doing this the comings days.

When that is done (in 2 days) I will contact all the remaining people on the list!

Thanks for all your support on this project!!

#26 — wednesdayayay · 2020-10-04

I’m very interested in at least a pair but was thinking of waiting until the matrix mixer is available

#27 — saiteron · 2020-10-04

would love 3 PCB/panel sets shipped tracked to USA if possible!

#28 — otoskope · 2020-10-05

Very useful. I’d love to get 3 x full kits, shipped to Sweden.

#29 — reverselandfill · 2020-10-05

#30 — Tremendm_Labs · 2020-10-05

#31 — efp3 · 2020-10-05

I’d like to get in on the kit if such a thing is still possible.

#36 — reverselandfill · 2020-10-07

sure

I’ll add you to the list, when the next pcb batch arrives I’ll contact everybody!

#37 — reverselandfill · 2020-10-08

more stuff shipped. next batch production is almost done at the factory.

#38 — reverselandfill · 2020-10-11

the factory made a mistake on the panels, so it will take a bit longer as they will have to make new ones

#39 — Robbertunist · 2020-10-15

Ughh, that’s a shame to read about the panel production issue @reverselandfill

Your package arrived yesterday, thankfully everything survived the journey here

#40 — reverselandfill · 2020-10-19

The new batch is in and ready to ship

I have a Mouser order of lm6172’s coming soon, I will start building the modules with my remaining stock.

I will PM everybody on the list!

About the shipping: I think I will have to use courier services, as the Postoffice regulations have been made so tedious that shipment of each package takes about 15minutes to setup. with the +20 packages I don’t think that will be pleasant. I’ll check the courier pricing and report back here!

And I started writing the build manual

#41 — reverselandfill · 2020-10-20

Shipping: I now ship with a courier service for tracked packages.

EU tracked: 20,- euro

International (USA, Norway etc): 25,- euro

Tracked shipping is quite fast with this service.

I can ship untracked (EU only) but that takes a lot of time to process (my time and yours) because the Postoffice has to comply to new regulations on international shipping, so I prefer the tracked option.

cost: 12,- euro

I’m soldering the modules as we speak, I’ll do the kits after that.
