Project: DIY Midi mixer.

Hi!
The last time it was a Guitar, now it is a MIDI controller i chose for my “autumn project”.
I want to build a Midi-Mixer.
It should have 4 Line faders, 1 Crossfader, some potentiometers (4 band eq and gain per chanel, master volume, headphone volume), some buttons (cue per chanel, CF assign).
This controller should be added to my setup of 2 x1 and my audio2 and a xone (which will be almost useless then).

What midi “brain” would you reccomend me?

It will be at most the faders + 20 potentiometers + 10 buttons.

And did i understand that right, that I can use normal faders / pots / buttons, just as i would use them in an analogue mixer?

Have you got any wiring examples?

I am planing to solder everything together in a solid metall box and i will publish a layout plan in a few days.

I hope you can support me.

Midibox is pretty expensive, you could get an arduino mega or a ChipKit Max. You require however more analogue inputs that available so you’d have to multiplex them.

I too am looking at building a mixer aswell, would this work, http://highlyliquid.com/midi-controllers/midi-cpu/

Thanks for the time and info

Definitly the umc+ by HaleMicrosystems it’s eazy, good an cheap and if you think 32 digital or analogue inputs isn’t enough you can link two togheter for 64 inputs.

It’s simply the best.

Got the old school UMC32 and I can vouch for its ease of use.

7

How many connections (“ins”) does a crossfader, a pot (guessing 1), a button (huessing 1) or a lien fader need?

So that i can figure out if 32 are enough.
And could i use a a normal crossfaderß

8

yes you can use normal crossfaders and everything takes just 1 input

Ok, so would that work out:

2 UMC 32+
1 UMC 32+ Bridge to connect them
4 Line Fader (http://www.thomann.de/de/denon_fader_dnx400.htm or mabe the ones from HaleMicro, but are they reliable?)
1 Crossfader (http://www.thomann.de/de/allenheath_crossfader_xone_22.htm)
23 Potentiometers for 4 Band eq + Gain per chanel + Headphone volume + Master Volume + Headphone Mix (http://www.halemicro.com/Products/Products.html)
8 switches for Crossfader assign (just some normal mini switches)
4 Buttons for Cue per chanel (any recommendations? Are those mini buttons like they are used in the X1 easy to solder or can you any easy alternatives?)

  • Some ribbon cables

So that would be a total of 40 inputs right? Then i would get some extra features to use all the possible 64 inputs, i dont wanna waste money :wink:

10

For cue i would use arcade, everything else looks perfect to me!

11

I dont mean cue points, i mean the cue to get the chanel into the headphone output and not to the main out.

12

My only thought is a shift button if you don’t mind mapping and that sort of thing… would mean less buttons needed or more buttons available (like some arcade buttons)

13

I know what you mean by cue but it looks soooo clean:

14

Thanks man, that actually looks rly good.
WHere did u get the case from? Did u build it urself?

I didn’y build it, but he bought the case here:
