*BUILD LOG* 'CDJ 2000'-style DIY Traktor controller

**MiL0** · 11-24-2010, 02:39 PM

progress is slow... just working out if I can make this thing using 2-3 xbox controllers as the midi brain. The problem is the encoders so I might have to use one of these as well:

Anyone know how to wire 12 encoders to this inputs on this controller? I'd probably need to use a button matrix and use 24 of the inputs (or 36 if the encoders include momentary push buttons). What about diodes?

edit: The good news is that I've got the clonescreen software working on external screens so the usb lcd display section that clones certain parts of Traktor should be straightforward to implement.

Sorry, can't help on this one. I used the more expensive BU0836X for ease of use. Look up the forum for help. It's a little slow going, but worth it in the end, as most questions are already answered.

Have you considered an Arduino with MUX shield?

Fantastic. This is exactly what I have had in mind for a few years now, and may get round to doing something similar myself.

I always use an external mixer (usually the club installation one) so don't like the all-in-one controllers. I also like the 'traditional' layout of decks either side a mixer, so two separate units is a great plus. The main thing I like is the move towards no reliance on the laptop screen for feedback - having the waveforms particularly.

I would have gone for more feedback separate from the screen itself in the way of LED feedback - such as led rings or something to indicate the position of the FX knobs.

I'd also go smaller format, I don't think I'd need the CDJ size jog wheel. I am trying to get something more the size of a Xone1D but with more LED feedback and embedded screen.

Annoyingly I use OSX so can't use your clone thing program, which is the key in all of this!

Good luck, I follow with great interest.

this is the thing.... I'd love to go with a midibox or Arduino implementation but my programming skills aren't up to scratch. Now, if there was a way to buy an Arduino and the Mux Shield, wire them together and download an existing bit of Arduino code that automatically assigns all the inputs on the Mux to midi outputs on the Arduino then I'd definitely go for it.

edit: perhaps it could be combined with this: http://www.coolcomponents.co.uk/cata...roducts_id=492

skenderbeg - totally agree with you about the paradigm for a dj setup... much prefer using the house mixer (but good to have midi channel controls on each 'cdj' just in case).

I feel your pain as far as programming. Im very new to arduino and am currently building a basic small scale controller with acrcade buttons, sliders, pots, and an xbox controller joystick. There is a TON of info and example code out there. I figure if you have the skills to do this hardware, the code would not be all that difficult. This gives you a non HID option (just run a small serial to midi program and you can send the info over USB) with a ton of I/Os

I loved the fact that I was able to program some complicated logic into my MIDIBOX.
For example, that way I was able to implement Shuttle (outer ring) and not just the jog dial form a re-purposed CD player jog-shuttle.

how's this going?

I plan to exchange my gamepad PCB with a Arduino Mega to controll both my controllers!
