Marcus Hobbs is a software developer focused on both creating software tools and using them to create visual and musical art. His first career was at Walt Disney Feature Animation whereas a digital artist he developed software used to create 3D artwork for Lion King, Pocahontas, Hercules, Atlantis, and Mickey’s Philharmagic, and Meet the Robinsons. He is currently developing mobile application software synthesizers that support microtonality, particularly focused on implementing the works of musical scale designer Erv Wilson. His iPhone and iPad application “Wilsonic” implements many of Wilson’s scale designs with interactive parameters so that musicians and composers can customize these designs to suit their values. He is a developer of “AudioKit Synth One”, a free open source additive software synthesizer which can import scales designed in Wilsonic.

Canadian composer of Ukrainian descent Marc Sabat (*1965) has been based in Berlin since 1999. He makes pieces for concert and installation settings, drawing inspiration from investigations of the sounding and perception of Just Intonation and of various music forms — folk, experimental and classical. He is a frequent collaborator, seeking fruitful interactions with other musicians and artists of visual and literary modes to find points of shared exploration and dialogue between various forms of experience and different cultural traditions.

Chalmers is also an actor with the Village Church Community Theater in Rancho Santa, California, where he resides, and has recently become a computer artist, having exhibited his music-theory generated polychrome plots in a number of venues in San Diego and one in San Francisco.
