1) The program uses hex because its a tracker based on LSDJ which uses hex, which is based on... Changing to decimal, while convenient for some people probably wont happen just because that is the lay of the land in piggydom.
2) I suggested soundfonts because that is currently the only file format that piggy supports predefined instruments loop points. Emu even has a utility to easily convert your format into soundfonts that should be drag and drop into your piggy projects:

I want more people to use soundfonts on piggy because i want it to become a more robust feature, and that will only come with more user adoption.
but anyways, thanks for letting me know you are a little baby so I can just avoid responding to your posts from now on!
