Proceedings of the International Conference on New Interfaces for Musical Expression

This paper describes the development of B-Keeper, a reatime beat tracking system implemented in Java and Max/MSP,which is capable of maintaining synchronisation between anelectronic sequencer and a drummer. This enables musicians to interact with electronic parts which are triggeredautomatically by the computer from performance information. We describe an implementation which functions withthe sequencer Ableton Live.
