Did you ever want to organize a jam session and let people with no previous musical experience jump in as well? Our riff machine will play super as long as all musicians in the room play in C major and/or A minor scale.


AudioPlexus aimed at creating and applying effective and innovative inclusion strategies in a mixed abilities group of young people in Itzehoe, Germany, through combined use of music and technology. It is supported by START a program of the Robert Bosch Stiftung, conducted in cooperation with the Goethe-Institut Thessaloniki and the German Association of Sociocultural Centers, supported by the John S. Latsis Public Benefit Foundation and the Bodossaki Foundation.

In our project we spread the sounds in 3 different Touch Boards and passed them through a sound mixer to create a space for interactions between the participants.

In case you want each board to play two riffs simultaneously or create crazy effects for your riffs you can set the board as a midi interface as explained here.
