I'm searching for music for some projects and I was thinking about getting filmstro but Im not sure if I got the payment system right. Is it like in Hitfilm Pro or Imerge Pro that you have to pay once and after one year you just don't get new updates or do I have to buy it again to keep using the songs? If it's like Hitfilm is there a chance to get the new songs? Do I get upgrade offers? Is the program even updated anymore?
