This is a video preview of RJC 1000 – a music production tool for creating music for “smart” music players, like the iPhone:

Using this software, you will get access to a growing number of reactive music modules such as the worldquantizer and twistybass. They will make it easy for you to create very engaging new music experiences by integrating the players accelerometer, microphone, compass or signal processing facilities into your music.

You can now create tracks where the movements of a listener control the melody of your song or the percussive noises in the listeners environment become part of the beat structure of your song.

Apply a range of realtime effects such as Eargasms or Dub Delays to the players microphone and combine the result with your music. This is reactive music, this is the 21st century 😉
