Does what it says it does.

This is a multitimbral Soundfont PLAYER! Its not a Soundfont editor.

To the user TranslationPolice - Youre bashing an app that never said it could do what you needed it to do in the 1st place. You need a Soundfont editor like Awave Studio (PC only) or Polyphone (Mac and PC) to edit Soundfonts. Once theyre edited, then you load them back into BS-16i. AFIAK there are no Soundfont editors for iOS.
