Morpheus is an aluminum percussion instrument made by the US company Freenotes. The aluminium tone bars give an incredibly pure, glassy sound which is well suited to pads as well as percussion. The instrument SC sampled is two and a half octaves, with the optional 'bass Wing' extension which offers six notes ranging another octave below that of the main unit. The keys are struck with custom mallets, also built by Freenotes, and ring freely afterwards. There is no damping mechanism.
