Modular Mechanical Systems

Modular Mechanical Systems (MMS) is a study of DIY handmade electronic music systems utilising light sensors and kinetic movement as audio and control sources. It explores tactile feedback systems where performance gestures and light control and reception enable cyclical sonic motifs. Rotating frames are mounted on bearings/motors that support panels of coloured acrylic that function as light filters. Below this, embedded into the surface, are photocells routed to bespoke circuitry based on the 40106 CMOS IC and 6N138 optocoupler. Thus, the initial soundworld is generated via standalone synthesisers that are tangible (performed via rotation by hand and motor) and highly responsive/performable via light. A range of complimentary MIDI controllers with computer-controlled LEDs and accelerometers are used to process and augment the other boxes. The modular design allows an infinite array of potential performance outcomes. MMS considers how each element–hardware and software, tangible and virtual–of the system can both enact and respond to generative processes through gestural control and light manipulation. The authors explore the role and affordances of each element and how it contributes towards the temporal sonic and visual space. This question arises during both the design and interactive performance. During performance, the authors explore shifting timbres, rhythms, and recurring sonic motifs by manipulating the boxes' configuration and their relationship to one another as well as light positions and filters. The interplay of emerging textures with the performers' responsiveness and interaction highlights the affordances of handmade bespoke systems toward musical structures in non-linear systems. While improvisation and experimentation are at the heart of the composition process, the system allows for curated and repeatable performance outcomes.
