Feed is a project of the Incidental team, which brings together developers, musicians, and designers, and deals with installations, performances, and applications, among other things.
Its idea is to manipulate and change the recorded sounds (or .wav blanks), to ring them, trim them, change their pitch and volume.
As in most cases, the interface (mostly consisting of multicolored circles, no more than six at a time) takes some getting used to, but it’s worth it.
