In this paper, we describe the concept of remixing playware, which allows sampling and remixing of both physical and functional (e.g. music content) aspects of a system. Such remixing playware has a number of distinguished features which are explained in the paper: user-configurable modularity, which allows the user to interact and manipulate with samples; user-guided behavior-based system, which allows music compositions to emerge from the way performer interacts with the instruments that provide the primitive behaviours; intelligent sampling as the ability of creating samples that allow anybody to remix with the samples ensuring an engaging outcome. The paper exemplifies remixing playware with a variety of implementations in RoboMusic concerts, the virtual MusicTiles app, the physical MagicCubes, the physical dices in Peter Gabriel concerts, and the S'n'S system. These examples focus on music creation and performance, based upon the concept of RoboMusic, and it is argued that the concept of remixing playware extends to many other application areas of playware
