A graphical interface for trajectory design and musical purposes


This paper presents a generic tool useful to design trajectories in the Max /MSP environment and applicable for musical purposes. The eight graphical tools of the trajectory program are exposed. Then, the creative potential of the use of trajectories is presented with examples. Conceptually based on the wave terrain synthesis, we present a usage of trajectory that allows to control two parameters through time. Based on previous works [7], the trajectory can also retrieve parameters according to a map on which the trajectory is drawn. Examples of synthesis and transformation according to this process are presented. Another interface based on the waveform segment synthesis is exposed: considering the coordinates as sample values, trajectory is used to fill two waveform segments in real-time by the successive values send by the tool. Trajectory can be used too as an interpoler, considering the design surface as a two-dimensional controller. Examples of use of trajectory as an external controller for vst plugins and for adaptive effects are presented. At least, I present future developments that use the new features of Max/MSP, javascript and user interface. The future trajectory patch will be able to manage up to 20 objects in a bigger interface, and will take under account the elevation axis.
