Pencil Fields
| I present an electronic music performance, developed in 2011-2012, based around a novel low-tech multidimensional gestural controller, exploiting the resistive properties of a 2D field of pencil markings on paper. A set of movable electrodes (plus, minus, ground), made from soldered stacks of coins, create a dynamic voltage potential field in the carbon layer, and another set of movable electrodes tap voltages from this field. These voltages are used to control complex sound engines in an analogue modular synthesizer. Both the voltage field and the tap electrodes can be moved freely. The design was inspired by previous research in complex mappings for advanced digital instruments, and provide a similarly dynamic playing environment for analogue synthesis. The interface is cheap to build, and provide flexible control over a large set of parameters. It is musically satisfying to play, and allow for a wide range of playing techniques, from wild exploration to subtle expressions. I also present an extensive inventory of the available playing techniques, motivated by the instrument, musically, conceptually and theatrically. The interface has been used in a number of performances in Sweden, Japan and the USA, with gradually gradually more complex sound engines. | sv | |
| A live performance of 10-15 minutes by Palle Dahlstedt on a custom built instrument, using a simple pencil drawing as a gestural interface for controlling complex analog synthesis (on a Bugbrand Modular). The instrument works by creating a voltage potential field in the graphite/pencil markings on the paper using custom movable electrodes made from coins. Then, control voltages are extracted from other points on the paper, controlling various aspects of the synthesized sound. | sv | |
