Hello everybody, I've just signed in on this awesome forum, but I'm not new to the MidiBox world :turned:

My first project was a portable Traktor controller for home-djing, It was built two years ago, and on the final revision it was called MidiTrakt2.0, it stil works really good, but it's quite small for serious Djing... I'll put some pics tomorrow...

So, now it's time for MidiTrakt3.0!

Basic specs are:
  • Analog In:
    • 3 faders (two channel mixer + x-fader)
    • 6 equalizer pots per channel (3 per channel)
    • 2 gain pots
    • 8 effect pots (4 per channel)

  • Digital In:
    • 16 button matrix (for combined effects/ loop/ beatjump and so on)
    • 2 cue
    • 2 kill bass
    • 8 effect switch (4 per channel)
    • 8 master/slave/sync/key (4 per channel)
    • 10 trigger buttons (happ style) play/pause/setcue/loop (5 per channel)
    • 4 encoder (2 jogwheel + 2 effect selectors)

  • Digital Out:
    • 2 kill bass
    • 2 cue
    • 8 master/slave/sync/key (4 per channel)
    • 2 encoder (effects selector)


This time I've put some time in pianification and routing, so I'll proceed this way:
I'll use a PIC core (already have this)
2 DIN modules
1 AIN module
1 DOUT module

All modules, except core, will be sandwitched on the bottom side of a PCB carring all the routings to and from the modules, and contains the mixer parts on the top side, then via some flat-cable appropriate signals are routed to the two transports (the part with play/pause/jogwheel/effects...)

I think that an image is better than a million words...

here is a schematics of the mixer layout:

here is the transport pcb:

the jog and happ-style buttons will be chassis-mounted, so the transport pcb covers only the top section...

Final dimensions should be about 600mm*300mm*70mm

Still have not decided the top panel finish... aluminium, acrilic, wood... it should be 3mm


Next will be the hard part (for me) programming everything to work on two midi channel... here I ask your help!

Here is a preview of the final parts placement, just like a standard Dj consolle, final dimensions will be 700x300; height will be just under 10cm

Front panel will be acrilic, with supports beetween mixer and jogs

Jogwheels will be 18cm aluminium discs I'll cover with some real vinils

I'm still looking on how to connect the jogwheel to the encoder (which is a 12 step encoder), nylon gears or belts and pulleys?

Not that I can assist with this in any way, shape or form, but I'd be interested to see how this turns out. I personally use timecoded vinyl with M-Audio Torq (cost effective) but would consider making one of these to use with Traktor if you get a nice result of out of it...good luck!
