The OscilloScoop — a iOS app with an animation-based interface to make looping grooves.
I love this—Greg Sabo has made a delightful little application that tosses up random quintets of Pandora descriptives. He wrote it as sort of an Oblique Strategies for musicians, to foster exploration.
I cordially dislike Pandora, because I think their approach to music recommendation is limited and autistic. (Also, it’s not a “Music Genome Project” if you’re classifying music by phenotype, dammit.) So I appreciate the taking-the-piss nature of Greg’s program. Plus, it’s a fun party game to get your musically-knowledgeable friends to try to name a band that fits the set of descriptives.
