traktorino's Issues

Issues with some pots and midi data range

Hi All,

I've just built a Traktorino from scratch and as per the title I need help.

1. The following potentiometers are not registering:

• Ch1 fader
• Ch2 gain
• Ch2 eq high
• Ch2 eq mid

2. Using Midi Monitor, the working pots have data values ranging between 64-126 (i.e. only 50% range). In other words the entire range of the potentiometers are only effecting from centre to max, and this translates the same way in Traktor Pro, for example: Turning Ch1 Eq Low only moves between centre and max, Ch2 fader only moves from 50% to 100% in the software.

I noticed at the bottom of the PCB there are points for test (continuity etc?). Is there any documentation on how to use them and what values to expect during trouble shooting? I do own a multimeter, and any help would be appreciated.

lastly, what's the best way to reduce the brightness of the leds? Can i replace the resisters with a higher value?

Cheers,
Eddie

Electronics sources

Hi, can you add the electronics source project files on the project ?

Thanks !

MIDI Input gets echoed onto MIDI Output, creates infinite send/receive loop in dj software

CC messages on MIDI Input are being echoed back out onto MIDI Output. This causes an infinite send/receive loop in the dj software.

Issue recreated in DJ Player Pro on iOS during led CC mapping.

Issue recreated in MIDI-OX on Windows 10, when both Traktorino MIDI Input and Output are opened

Traktion profile

Started a MIDI profile on Traktion

<?xml version="1.0" encoding="UTF-8"?>

<MIDICUSTOMCONTROLSURFACE name="Traktorihno" eatsMidi="0" channels="8" parameter
s="18">
  <MAPPING id="65538" channel="11" function="1800" note="-1"/>
  <MAPPING id="65544" channel="11" function="1801" note="-1"/>
  <MAPPING id="0" channel="1" function="1100" note="36"/>
  <MAPPING id="0" channel="1" function="1101" note="48"/>
  <MAPPING id="65537" channel="11" function="1700" note="-1"/>
</MIDICUSTOMCONTROLSURFACE>

Provide test code (MIDI or Arduino) to test out the LEDs once the assembly is finished

Once the assembly is finished it would be nice to have a test program to test out all the LEDs, two solutions could be used :

• some sort of python script or other that talks to midi and turns on and off the LEDs by sending MIDI signales

• an arduino sketch that goes through all the LEDs and turns them on and off and prints out some debug information on the serial port.

Mixxx profile

It would be nice to be able to use traktorino with a Mixxx https://www.mixxx.org/ the open source DJ software.

I've started a profile by detecting the Input Mapping, but am having trouble with the output mapping (turn on and off LEDs)

Ardour profile

It would be nice to have an ardour profile shared setup (which can end up being contributed upstream to ardour).

Add Bill of Material and PCB project source files

Hi, it is great project. I would like to colaborate and it would be great if you share PCB project source files if not I can help you to export it to an open source software like kicad. Thank you again for sharing this with us!

Add extra buttons with digital pins?

I wish to add extra buttons to Traktorino using digital pins. Is it possibe?
What is the best way to do this?

I have got D13 to work by

const byte muxNButtons = 13; // *coloque aqui o numero de entradas digitais utilizadas no multiplexer
const byte NButtons = 1; // *coloque aqui o numero de entradas digitais utilizadas
const byte totalButtons = muxNButtons + NButtons;
const byte muxButtonPin[muxNButtons] = {0, 1, 2, 3, 4, 5, 9, 10, 11, 12, 13, 14, 15}; // *neste array coloque na ordem desejada os pinos das portas digitais utilizadas
const byte buttonPin[NButtons] = {13}; // *neste array coloque na ordem desejada os pinos das portas digitais utilizadas
int buttonCState[totalButtons] = {0}; // estado atual da porta digital
int buttonPState[totalButtons] = {0}; // estado previo da porta `digital

But I cannot get other pins to work like D13. Am I missing something?

Browse Encoder click not mapped to any MIDI output message

Clicking the Browse encoder does not result in a MIDI message being send out.

Is the encoder click currently wired to a pin via the PCB? If so, where does it go? If not, a possible workaround would to be to wire it up to a free digital pin on the Arduino (hacking!), and read that digital pin from the code.
