A granular instrument requires the same daily practice as any acoustic instrument to sound compelling

Roads designed the Creatovox real-time granular instrument (1999–2000) expecting expressive performance, but every public demonstration disappointed him — not because of design flaws, but because he had not practiced enough: ‘a virtuoso instrument requires a virtuoso performer who practices the instrument every day.’ The lesson generalizes: designing or coding a new granular instrument does not substitute for performance practice, and making a satisfying piece with rich multiscale architecture purely from live performance remains daunting. Contemporary scrubbing-interface instruments (like Borderlands for iPad) lower the entry barrier but do not eliminate the need for developed virtuosity.

Examples

Creatovox (1999): a keyboard-like MIDI interface for SuperCollider granular synthesis whose demos underwhelmed for lack of practice; Borderlands (iPad): a scrubbing granular interface still rewarding practice.

Assessment

Why did Roads’s Creatovox demonstrations disappoint despite the instrument’s technical quality, and what does this imply for anyone building a new granular instrument?
