This paper presents how the modem game controller Wi-imote can be used to control Mozart's dice music. The proposed method allows users to explore and expand their experience with endless music within space where note measures are arranged in a 2-layer structure that can be treated as a playlist. Experimental results show that the proposed organization of measures gives higher melodic similarity between consequent parts according to melodic distance measures such as distribution of pitch classes, distribution of intervals and distribution of note durations. The result is a system that allows user to create different music than in Mozart's original Dice game and allows exploration of endless music. We also compare the use of different metrics for organizing individual layers in order to achieve melodically more meaningful music.
