Midi Controller Toggle navigation

In this project we are building a Midi controller. Our controller will have 12 buttons, 4 linear potentiometer and 2 sliding potentiometers. Each will be assign to control a software, the software we are using in this project is Traktor Pro. Traktor Pro is a DJ software that allows to be controlled by external devices. Our controller will communicate with this software using arduino Uno as the brain of our Midi controller, also Serial-2-Midi converter software to convert bits send by arduino into Midi messages.
