Midibox 64 DIN Grounding - Check my work...

Testing/Troubleshooting
1

Dearest helpful midiboxers:

I am currently embarking on my first midibox project, a Traktor control surface based on a Midibox 64.  The interested can follow my progress at http://www.midibox.org/dokuwiki/doku.php?id=questionable (the Midibox Wiki) and at my blog http://www.nonsilence.com.

I’ve just started wiring the buttons, and I’m unsure that I am handling the grounding correctly.  In the image below, you can see a set of buttons, each with a rainbow wire coming from the DIN board to the button.  I think I’ve got that handled correctly.  However, I am questioning the black wire (from VS on the DIN) coming into the nearest button, and then the yellow wires that then travel from button to button for the remaining buttons. 

Am I doing this correctly?

(That’s a yes) Looking good, more pictures, pwease?

Thanks a bunch for the review.  I was hoping I was doing it correctly, but stopped progress until I knew for sure, as I didn’t want to have to go back and redo things.

Much appreciated. 

Now, I understand I need to use star grounding for the AIN pots and faders.  Does that mean that I must bring every pot to a common point individually, or do I just need to daisy chain them as I’ve done the DIN buttons, and then bring the endpoints of those to a common ground?

The “root form” of starwiring means bringing each pot’s ground to one common point. Obviously that’s gonna be wire hell if you have a lot of pots :wink: Hence most people go with this:

Okay.  Thanks for clearing that up.  I had come across that diagram before, but can never seem to find it when I’m looking. 

And yes, I’ll be taking plenty more pictures.
