Just out of curiousity on this project. What about pitch control? The set-up I'm working on uses a Laptop running Traktor and looking for some sort of MIDI controller I can use to scratch and cue, but still use the analog mixer I have. The only way I see it working without using two soundcards out of the laptop, which is not feasible. Basically the set-up would be with 2 MIDI controllers like this, my laptop running Traktor, and the AEM-100i. I want to be able to use a headphone for cue purposes and have the outputs coming through the mains out of the AEM... I'm not asking for it to be done for me, just looking for some guidance on getting where I want to be with this. I've looked at the 'Commercial' offerings, and the only one that fit's what I'm looking for is the Denon DN-S5500. That's a lot of money though. I'd rather try my hand at this and learn something from it. ;) I looked at the Traktorizer one, but then I found this one, and this one seems more capable of doing what I am looking to do with it. I'm new to this digital world of DJing, and the only work I really have done with MIDI is from synths and drum machines. No programing it or anything of this nature. I have programming experience using C/C++, and a little ASM. Never done any PIC before, but from what I can see it's very much the same.
