The first Music Hack Day Boston event was held at Microsoft NERD in Cambridge, where hundreds of hackers gathered to create the next generation of music tech. The event kicked off with API demos and project pitches, followed by a full day of hacking, with many participants opting for an extra night of coding. When the demos began, 56 completed hacks were showcased, including Twilio-powered projects such as muTxt, Music Snob Jeopardy, and Ctrl+Freak, which leveraged APIs from Echo Nest, Rdio, YouTube, and others to create innovative music-related applications. Other notable hacks included Neurofeedback, a project that used EEGs and machine learning to generate music based on the creator's emotional state, and Twizam, a simple hack that allowed users to call in, record a snippet of a song, and receive its name and artist via SMS. The event was hosted by Microsoft and Echo Nest, with many participants showcasing their projects and receiving recognition for their innovative ideas.
