Polyphone Soundfont Editor

Polyphone is a soundfont editor for quickly designing musical instruments. It will help you to create and edit a musical instrument based on samples, using the sf2 format.

More than a simple editor, Polyphone has been designed to efficiently deal with big sets of instruments involving a large amount of data.

The software supports both of desktop(Windows/Mac/Linux) and Raspberry Pi. Free to use, under GNU GPL 3.0 license.
