vMIX 2.0 is here (or almost, anyway…)

Just in time for our appearance at the “Homemade Festival” in Glarus, I finished the first version of my new “virtual video mixing console”. Version 1.0 had just some buttons, 8 rotary encoders and 8 faders. It was getting of age and I didn’t like to perform with it anymore. So, months of work and about 2000 solder points later, a dream comes true…
USB Interface, 35 Potentiometers with 35 Ledrings, 8 Faders, 6 Microprocessors, expandable…
Read on for the photos:

I wanted something more like an audio desk, with a LOT of buttons, real potentiometers with center detent - but with led rings, so I can load presets and see where my pots are.
“So why not put in encoders when you go into the hassle of soldering your own ledrings?” - you might ask. Well, I simply don’t like rotary encoders. They’re fine for traveling through a menu of a MP3 player, or maybe in studio work, but not for live performance. I need to know where I am, physically, without looking away from the projection. I need to feel the start, the middle, the end. I want to feel the speed at which I’m turning up the contrast…
And I want every parameter to be accessible, anytime.

That’s three of the 5 channel controller boards, freshly edged:

Then I painted them with soldering paste and put them into an old swiss “Raclette”-Oven:

That will be a ledring (unfortunately the led’s I need are still out of stock…)

Four potentiometer boards with their ledringboards

Then I was too busy soldering and finding bugs, so I forgot to take pictures…
Here it is, tata!

One channel isn’t working, so I left it out for the moment, …

A look from the under side. I know the whole unit should be shielded, but this would be too sad…

A closer look:

And here’s the master processor, getting data from the 5 (4) channels and communicating via USB with my Max patch…

  2. Hi,

    Interesting project. Could you give more details on what the mixer does, how it is used and what the microcontrollers are used for?

  3. Hi there,

    WOW! What an amazing piece of work! It would be great if you could post schematics and/or code used in the microprocessors. It looks like you have each “channel strip” going to its own processor, and then into the master processor taking in all the data (over SPI? I2C?) and handling the USB communication with a PC. I know this project was from some time ago, but I still yearn for more details :D

  4. […] Scott reminded me yesterday that I’ve never published the sources of my vMix USB mixing desk. […]

  5. Nice project and awesome finish!
    Would it be possible to see a video of it in use?
    Did you get the leds that was out of stock, later on?

  6. @ Håkon:

    You can see the thing in action in Tobias Bühlers short documentary about the Videobass:
    I still regularly use it for our performances (with functioning led rings…)
