Many fascinating new developments in the area bowed stringed instruments have been developed in recent years. However, the majority of these new applications are either not well known, used orconsidered in a broader context by their target users. The necessaryexchange between the world of developers and the players is ratherlimited. A group of performers, researchers, instrument developersand composers was founded in order to share expertise and experiences and to give each other feedback on the work done to developnew instruments. Instruments incorporating new interfaces, synthesis methods, sensor technology, new materials like carbon fiber andwood composites as well as composite materials and research outcome are presented and discussed in the group. This paper gives anintroduction to the group and reports about activities and outcomesin the last two years.
