    Kangas Sound Editor

    Kangas Sound Editor

    Synthesizer, mixing, sound effects, music composition and production.

    This kangaroo-themed program allows the user to create their own music and sound effects, effectively from scratch. There are two variants of the program: Kangas Sound Editor which requires MySQL for its database, and Kangas Sound Editor QI which does not (it uses an internal database - HSQLDB - instead). Kangas Sound Editor (QI) uses a system of boxes or cells, which are placed by the user onto a timeline using drag-and-drop, and which represent entities such as chords, repetition, and individual sounds or notes. The program's database allows the user to create and store harmonics, used for constructing melodic instruments, and anti-harmonics, which are used for constructing percussion instruments. Users can collaborate with and build on the work of others via an XML import/export facility.
