AbstractpMix-touch is an extension of the author’s pMix software[1], which is a composition, sound design and performance tool based on multi-layered preset interpolation, that was originally created as a MaxMSP library (int.lib) and presented in[2].

pMix facilitates the control of VST plug-in parameters from a rich 2D graphical interface that has been designed to provide intuitive feedback and to allow the control of multiple parts of a signal processing graph from one abstract “interpolation space? (hence multi-layered preset interpolation). The software comes with a collection of sound generation and processing plug-ins that have been specially developed with parameter interpolation in mind. The plug-ins cover a range of experimental DSP techniques used in computer music (noise generators, resonators, FM synthesis, formant filtering, frequency shifting). While the main pMix application runs on a computer, pMix-touch uses an embedded web server to expose this interface to a wide variety of client devices including tablets, smart phones or other computers. The interface is rendered using client side JavaScript and the HTML5 canvas[4], which makes it highly portable and allows it to benefit from speed increases that come as result of the “browser wars?. Touch events provide new ways to interact with the preset interpolator by designing, navigating and controlling interpolation spaces using multi-touch gestures. The presentation will introduce pMix-touch and discuss the design decisions, potential benefits and practical issues of browser-based interfaces for remote-controlling audio software.

pMix was awarded the second prize at the LOMUS 2008 International Music Contest[5]. It is available for free on the Mac App Store[1]. It was recently chosen as one of the interfaces used in the Inventor Composer Coaction[3] at the University of Edinburgh.
