The renowned guitarist & musician Adrian Belew is famous for his innovative sounds, both in his solo career and in his work with Zappa, Bowie, King Crimson, NIN etc. As part of his app strategy, his aim was to design and develop a professional audio tool for musicians, sound designers and studio engineers - something that would enable his audio exploration but would be a truly mobile solution. FLUX:FX is a multi-effect audio processor app for the iPad that lets the users 'play' their effects. Designed as a native touchscreen digital platform for both studio and live use, the app provides a modular construction box of 31 audio FX blocks that embrace abstract sound design and encourage out-of-the-box creativity instead of simply replicating existing musical equipment (such as digital versions of guitar amplifiers). The app features a minimalist interface with fluid multitouch controls that let users manipulate a sound source into something entirely new with an almost unlimited range of effect options. Guitar, bass, synth, drums, vocals, DJ setup, violin etc - essentially any audio signal can be processed in real-time by FLUX:FX.
