This is the second version of M O D U L O, which is a real-time composition tool in the form of a board game and can be played on an android device. In this game
there is a close connection between the musical structure and its symbolic representation on the board. The game pieces represent arithmetic operations. These are applied one after the other along a path of the shortest adjacent distances starting from a source tile representing the sequence id(N 0 ) = 0, 1, 2, 3, 4, .... The resulting altered mathematical sequences are converted into sounds. The opponents in this two-person game, place alternately tiles on the board or move them. The goal of the game is to establish an own path by skillful moves, which consists of operations and operands as mutually different as possible and at the same time to prevent the opponent from doing so.
