Katch Posted April 10, 2006 Report Share Posted April 10, 2006 Nothing on the market quite seemed to fit the bill when I started looking for a control surface to handle Traktor and Ableton (along with many other VSTis and Music Apps). So I got to thinking, surely it can't be too hard to build a custom interface.... a few googles later and I find you guys.Looks like much of the hard work has been done already so hopefully this should be a pretty straight forward project.So here's the concept; (don't you love ctrl c & ctrl v)32 Rotarys8 Faders (2 actual technics pitch controller spares)24 Buttons5 LEDs********************************************************Right about here is where I start needing a little help;Shopping list;Core Module2 x AIN ModuleDIN ModuleDOUT Module32 Rotarys8 Faders (2 actual technics pitch controller spares)24 Buttons5 LEDsAn EnclosureA Power SupplyYour initial thoughts reactions and input would help a great deal.Tnx Quote Link to comment Share on other sites More sharing options...
Katch Posted April 10, 2006 Author Report Share Posted April 10, 2006 Quick schematic;The 5 LEDs are gonna need to light up to show that CUE is actively listening to a given channel. Am I on the right track here? Quote Link to comment Share on other sites More sharing options...
DavidBanner Posted April 10, 2006 Report Share Posted April 10, 2006 Hey Katch,You seem to be on the right track. A tip - if you're going to order the PCBs and or Kits from smashTv's site - take a look at the board layout on his site - very informative and also some of the jumpers have been moved around, so it's worth checking you have everything right from the get-go.

ranger930 Posted April 10, 2006 Report Share Posted April 10, 2006 hi katch,nice design, but traktor Version2 and a think traktor version 3 is not able to send midi message out from the computer to the controller, and that very bad, because i am building a controller like you, and i wan't to havestatus led's and LED VU Meter, please look under design concept in this forum, there is my design ( not finfished and not build )@all member: i need information about osc protocol, any idea's ?after my holiday i will start.greetings ranger930 Quote Link to comment Share on other sites More sharing options...
Katch Posted April 10, 2006 Author Report Share Posted April 10, 2006 hmmm,maybe I'll just drop the DoutX module all together for the sake of simplicity. Quote Link to comment Share on other sites More sharing options...
ranger930 Posted April 10, 2006 Report Share Posted April 10, 2006 hi,you can use a switch and a led after that, i thing it must be work too !greetz ranger930 Quote Link to comment Share on other sites More sharing options...

You don't need Traktor to send MIDI messges to control the cue LEDs. Just let your MIDIBox application turn them on for you. So, instead of:Button press---> MIDIBox app ---> Traktor ---> MIDIBox app ---> LED onYou have simply:Button press ---> MIDIBox app ---> LED on | | | v TraktorThe VU meter, however, won't work with Traktor because it doesn't send MIDI out messages. That part is true.-drin Quote Link to comment Share on other sites More sharing options...
ranger930 Posted April 10, 2006 Report Share Posted April 10, 2006 @katch:the 2 fader from the technics sl 1210mk turntables are linear ?@drin:yes i know, if i'm using the mouse too, i can do anything i want with the mouse , start,stop,.....,the best thing is a real control from the computer, but not with traktor,i have read something in native intruments forum about osc protocol ( english correct ? )ni works on it to make traktor 3 able to send information out, i hope to get information about thatableton can send midi messages ?greetz ranger930 Quote Link to comment Share on other sites More sharing options...
drin Posted April 10, 2006 Report Share Posted April 10, 2006 yes i know, if i'm using the mouse too, i can do anything i want with the mouse , start,stop,.....,My point was that you don't need Traktor to control status LEDs.i have read something in native intruments forum about osc protocol ( english correct ? )ni works on it to make traktor 3 able to send information out, i hope to get information about thatNI can't even get recording to work right in Traktor 3! There's a HUGE thread on the NI forum about the recording bug, and MANY threads about the numerous bugs that have been present since 2.0 and still haven't been fixed! I think having OSC is a dream - it won't happen in this version, and if by some miracle they do get it working it'll be so full of bugs it'll be unusable.-drin Quote Link to comment Share on other sites More sharing options...
Katch Posted April 10, 2006 Author Report Share Posted April 10, 2006 @katch:the 2 fader from the technics sl 1210mk turntables are linear ?Yup, these should be ok right? I can even source the fader plates to build into my controller. I really like the idea of having a controller with pitch control which doesn't just feel like my turntables but actually is the same.

dengel Posted April 11, 2006 Report Share Posted April 11, 2006 Hey, Katch! I'm also working on an Ableton controller. One thing that I'm wondering is how you intend to launch clips with the arrangement shown? Perhaps I have been using Ableton wrong all this time? :)I see what looks like a single momentary over the fader channels - do you program everything into scenes? If so, do you use Ableton in a live setting much? I know of some ableton DJs that use a "MegaSet" and replace scenes by using the mouse. Just interested how you personally get around the inability to load new live sets on the fly W/O stopping audio? Quote Link to comment Share on other sites More sharing options...
Wild_Weasel Posted April 11, 2006 Report Share Posted April 11, 2006 Hi!Take care as the 1210's pitch faders are linear but not 10k ohm. These are 20k. I know this because I was messing around with a broken technics the other day.Regards Michael Quote Link to comment Share on other sites More sharing options...
Rowan Posted April 11, 2006 Report Share Posted April 11, 2006 20k should be alright, I did a MB64 with 20k and it was fine Quote Link to comment Share on other sites More sharing options...
Katch Posted April 12, 2006 Author Report Share Posted April 12, 2006 Is it going to be ok to mix 20k and 10k variable resistors?i.e. 20ks on the pitch faders and 10ks on the POTs and 5 channel faders? Quote Link to comment Share on other sites More sharing options...
moebius Posted April 12, 2006 Report Share Posted April 12, 2006 Yup,Mixing different potentiometer values is ok.Moebius Quote Link to comment Share on other sites More sharing options...
