Thanks for responding. After your comment I understand what I'm looking for. There is a program called IDES which can be downloaded for free from the casio website. Among the options delivering this program, there is an option that allows, through sound samples in wave format, generate a tone with extension Z06. This application is called "wave converter" and works perfectly. What I need is that conversion becomes Tn7 and it may be necessary to update the program to the new versions of CASIO. So like me, there are millions of users who are looking for the same. Best regards.
