The RjDj music generator software uses sensor data collected through your iPhone’s mic, accelerometer, etc to alter its audible output. The way in which it uses this data is determined by the particular ‘scene’ loaded – one scene uses ambient noise levels to modify a simple melody, while another triggers breakbeats via movement.

I’m guessing dynamic music could work on a platform like iPhone if executed correctly, but I wish the developer would refrain from the sensationalist “digital drug” references – they seem unnecessary. – RjDJ [via Synthtopia]
