Well guys, it has been a long time ago, but.. now i am finally finished with my midicontroller. The last functionality i want to build in, is touch sensitivity for my jogwheels. The requested hardware for this is already realised, but i have some questions about the software. According to this and this article it is possible to add touchsensors using J14 of the mainboard in combination with the DINX modules. But how can i activate this in the software? How can i determine wich pins of the DINX modules i use for touch sensing? How can i program the sensitivity? I will post some recent photo's of my mixer later ;).. Thx in advance

Well guys, forget about my last post. I have come to the conclusion that the pic based core is not gonna work with my fresh new usb midi cable :(. I've tried it on another computer with a MIDI IN and MIDI OUT connection (so no USB-MIDI converter included) and it all worked well. It is possible to upload a new app to the controller with this computer, but not with my usb-midi cable :(. My question at the moment is: Is an MIDI-IN and MIDI-OUT required on your computer, to use the midibox with? Or is it anyway possible with a usb-midi converter too? Thx in advance

Last week i receiver the core pic module, including the pic PIC18F452 with bootloader. I soldered all parts on the module (except for the 2 isolated cables). This afternoon i have installed the Developing Applications succesfully, and also succesfully build my own program, for test purposes.. After installing the mios studio i connected my laptop (sony vaio FW41EH, windows 7) with the pic-core-module using an USB-midi cable(/converter). I received messages from the pic every 2 secs, indicating a living pic :P But after that i ran into the following problem: When i select my usb-midi-cable by midi out and midi in in mios studio, the studio can not recognize my pic :S But when i select my usb-midi-cable by midi in and another midi-device by midi out (for example a midi-yoke 'device') mios says 'bootloader is up and running' when i hit the query button. Concluding this, it means that my pic is recognized only, when another midi-device is selected by the midi-out in mios-studio. I have tested the midi-in and midi-out connection between my pc and the pic using the troubleshooting page, but everything seems to work fine. Does anybody have any experience with this kind of problems, or does anybody have a solutions or hint to a solution?

Thnx Shnizzle, great answer on my question, explaining everything. You are right by the current saving. It aint much compared to the current consumption of the lcd. The reasing for asking is that i found some beautifull knobs on farnell.com, but only deliverable with 100k resistance. Referring to your answer i can better search further for the same beautifull knobs, but with 10k resistance. ;)

Well, i searched the wiki, ucapps and the forum but not really a technical answer to my question. I think potentiometers with a bigger resistance are better because in that case there flows less current through the potentiometer. This will result in a smaller current consumption for the midicontroller. I only need this statement to be confirmed by anybody...

Do the potentiometers really need to be 10k? I thought 100k or 1000k is OK too.. What are the (dis)advantages of a bigger/smaller resistance?

Thx guys, for the links to the tutorial and wiki. I red some info on the wiki, but i guess there is much more. The tutorial is for the sofware only i guess? Wether or not, i will check it out soon :). Normally spoken i will do first things first, but considering the deliverytime of the coremodule (including pic) i would like to order this coremodule as soon as possible. But i have to specify the choice of PIC-uc and a header. Considering that i am going to create my midibox controller base on the 64e, i have to choose the PIC18F452, with header 0000 0000 0000 0000 (because i plan to use a normal LCD (16*2), and id doesn't care, because i use 1 core only) right?

He Punk, thx for your reply. Considering your answers on the STM-32 core choice, i think i can better choose for the PIC8 based core, because this one is well supported by ucapps. You are talking about the midibox64 and midibox64e, but what is the difference? Is there only difference in the software? Both are running on a PIC based core with several DIN and DOUT and AIN modules right? Is it true that the midibox64 does NOT support rotary encoders, but the midibox64 does well? About the controllers i asked questions about. I think i know a local dealer which i can visit, so i can see and Feel what kind of controllers i will buy :D...

Hello all! I am a newbie who is planning to build a midi controller for Traktor Pro. Well, I red a lot of information on the whole ucapps.de, but i have still some questions. I would like to build a midi controller for Traktor Pro, with the next functionality: - A stm-32 based core module - Some rotary or sliding(faders) potmeters (quantity not determined yet) - Some buttons with led-indication in it (idem) - A few rotary encoders (idem) - USB-connection with my laptop And here are my questions: 1. How do i 'tell' (/program) the STM32 on which DIN-addresses my rotary encoders are located? Because these uses 2 digital inputs i red.. 2. Does anybody have experience on controlling LED's (dig. out) with use of the led-feedback in Traktor Pro? 3. When i buy the STM-board in SmashTV's shop the bootloader is already programmed. But where can i find the (template) software for the STM32? 4. The USB-connection property reduces my choice to the STM32, doesn't it? The PIC does not support USB-connection, right? Parts: Rotary pot: I would like to have rotary potmeters like the DJM-800 has: - 270 degrees - small head (don't know the exact english word) 5. Does anybody know where to find this kind of knobs? Fader pot : I would like to have 2 different kinds of faders: 1. A stiff/rough fader, to control pitch, fader travel 100mm (i think stiff/rough is the best for pitch control) 2. A fine fader to control deck-volume 80mm 6. Does anybody now where to find these faders? Buttons : For the buttons i would like to have them with an LED in the button (also like DJM800). The LED is controller by Traktor Pro indicating the state of that button. 7. Anybody know where to find these? Thanx in advance!
