The open-source DIY MIDI Controller for DJs.

Similar projects worth following
The Traktorino is a powerful low-cost DIY MIDI Controller. In its core, there’s a shield that connects to an Arduino Uno, a powerful and affordable microcontroller. With open-source hardware and software, it's totally hackable!
The Traktorino is a MIDI class compliant device, designed for controlling the Traktor DJ software. It has several features and custom made mappings, so you can take the most of the software. However, it can do much more than that. The Traktorino can control any software that accepts MIDI, like Ableton Live, Serato, FL Studio, Logic, etc.

The Traktorino was made for are DJs and electronic musicians that want an affordable MIDI controller, or just want to learn about electronics and programming, while making their own MIDI controller! 

Several countries suffer from abusive prices, and getting quality music equipment can be really hard. The Traktorino gives the chance to people to learn, and build their own MIDI controller for an affordable price. Buy everything on your local electronic shop, laser cut in the closer fab lab, or buy on line with the Nerd Musician to help funding other cool projects like that!

The Traktorino is USB-MIDI class compliant device and works with any DAW that accepts MIDI. Just plug and play. It's designed for Taktor, with some mappings available, however, it can be used with Ableton Live, Serato, FL Studio, etc.

Control your mixer, apply effects, control the transport, browse your tracks, and check your levels with the led VU meter! The Traktorino was already featured in websites like DJ Tech Tools!

I have built this, and have some issues. Some of the potentiometers are not registering (CH1 Fader, CH2 Gain, CH2 EQ High, CH2 EQ Mid do not work).  The ones that do work only have a data range from 69 to 126 (testing with MIDI Monitor) and when i turn/slide the potentiometers they're not smooth e.g. going from low to high, it quickly moves from 69 to 122 then very slow to get to 126 (also does this in the Traktor Pro software).  Can anyone help me to troubleshoot these issues?

I did not find the traktorino files either. 

Could you specify which the folder is, please?

Hi. I watch the content of this Amateur radio, a very suitable project for beginners and experienced, now I will try my hand in this project,I plan to Arduino novichek,but it is very interesting to see how it works,I would like more such projects, as where I live easier naichi Arduino and radio components than to buy professional expensive equipment.
