That’s good news man!
Always remember to back up the sounds of each project you work on so you have the sounds no matter what happens to your sound kits folder!
I think FL 21 does this for you automatically now if you create a project folder, but this can also be done through File -> Export -> Project data files (it’s really easy and fast to do).
Keep at it man, you are determined, and that’s what it takes to learn beatmaking!
