Giada is a free, minimal, hardcore loop player for Linux.

It handles up to 12 audio channels playable in a loop mode - loop machine way - or in a single shot mode - drum machine way.
Giada aims to be a compact and portable virtual device for Linux (and maybe for Windows and Mac in the future) for production use and live sets.
