CurvJ/Curvaceous: Curvaceous is a computer program which generates MIDI sequencer
files for exploring kinds of ensemble coordination made possible with
the computer-controlled synthesizer.
It can generate any number of independently accelerating or
decelerating pulses, each with its own pitch sequence and MIDI velocity
In addition, the program can create groups of lines which gradually
diverge from or converge to one of these accelerating or
decelerating lines in terms of rhythm, pitch (using MIDI pitch bend
values), or both.
Software for Exploring the Potentials of the Computer as Performer/Conductor
CurvJ is a Java, GUI-enabled version of Curvaceous.
Except for the divergence/convergence processing (to be added in an
upcoming release), it has all the
capabilities of the original program and it can be much more easily
configured, either through the Java Swing GUI and/or with Java
Much of the material in Fortuin's Branchings (1993) and Untitled #3: A Transcendental Etude for Computer-Controlled Keyboard (1987) was generated by Curvaceous,
and the tempo curves for the acoustic instrumental piece Time Lines (1994) as well.
