This paper describes a software package developed in MAX, for using the gestures of a performer as control factors for music, via the Buchla's Lightning. The software not only tracks the x and y coordinates of each transmitter, but also calculates the direction, speed and acceleration of their movements in the whole space and relatively to each other. The program is very configurable, allowing to calibrate the data evaluation and to adjust the sampling rate of the values sent by the Lightning. These features have been applied to composition in two different approaches: as an interactive choreographic environment, and as a performing interface for musicians.
