PV_Tools is a project developed to control audio & midi parameters through a simple webcam, an ip cam or even a desktop grab window. It's an upgrade of my older project OAR. It isolates and captures the movement of a coloured object (red, green or blue) and it "translates" it into the cartesian coordinates of a matrix window.
    According to the user's presets this is scheduled to interact with several audio or midi controllers like a pitch shifter, a theremin simulator, a midi synth, a sound font player etc. PV_Tools, at the time, are designed for a couple of colour trackers, and quadraphonic sound.
    I use it in many of my projects as well as for educational purposes. In order to be open and freely developed, it is presented as an open max collective patcher.
    This project is exclusively based on MAX 8
