FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.
FMS is a tool to create all kinds of sounds from scratch. You can play any sound (sine, triangular, vowels, etc.) with any property settings (frequency, volume, balance, sweep, etc.) and modulations thereof. It also features tools to save sounds, play .MUS music, graphically display sounds, and make real noise.
bcr harms takes a model of the quantum harmonic oscillator and adapts it as a soft synth. It lets you hear and see how the oscillator wave functions evolve in real-time as you modify amplitudes and other parameters. The user interface is based on and integrates with the BCR2000 MIDI controller, but the application can be used without a controller.
