Title A name given to the resource Kangaroo pouch tone-tool Subject The topic of the resource Free Music Description An account of the resource Steel, brass, PVC pipe, paper roll, sewing machine belt, electronics. This machine demonstrates the method used by Grainger and Cross to control oscillators through the use of connected ‘tone arms’ and cut paper ‘scores’. Whereas Grainger and Cross hand-turned their eight oscillator tone-tool, this scaled-down version is operated by a hand crank that enables the looping score to be played in either direction. Here, a digital oscillator created using the Arduino electronics platform and the Mozzi software library is controlled using two paper rolls in the shape of Grainger’s ‘Hills and Dales’ scores. One roll controls the pitch of the oscillator while the other controls the volume level.
