This adds a vibraphone to Jens Pianist project: http://scratch.mit.edu/projects/Jens/12908 Here is Jens description: This project plays random chords and analyzes them on screen. Seven kinds of chords are randomly produced: Major Minor Dominant seventh Minor seventh Dimished Suspended fourth Suspended fourth and seventh Chords are played at random intervals using random bass-keys and a set of five random arpeggios. This produces an 'artsy' Rachmaninoff-like kind of music. Have fun!
