I just discover a nice timeline editor that can be combined with EyesWeb by OSC :
Duration controls change over time. With a simple one window approach, the cross platform stand alone application manages lists of tracks to compose changing data over a fixed duration.
The application sends values over OSC and can be configured through OSC messages.
Duration is open source and completely free to use in your art, research, or commercial projects.
You can download it here : http://www.duration.cc/
