A system for selecting the stitch forming organs for textile machines; in particular for circular machines for knitwear, contemplates software management such as to update the status of each individual lever () of an activator (), as well as in predetermined time intervals corresponding to the angular positions that occur every K needles () or sinkers (), where K is the number of levers () in line of the activator (), also in other time intervals corresponding to intermediate angular positions includes between 1 and K; the correct value of these angular positions is determined by the profile of the lever () of the activator ().
