Kangas Sound Editor lets you synthesize sound effects and music effectively from scratch. Musical pitches are constructed using a system of frequency ratios, rather than the conventional equal-temperament notation. MIDI pitch numbers can be used to specify a base note from which other notes are relative. The user interface uses a system of cells or boxes, which are placed using drag and drop, and that have associated properties which describe various characteristics of the instrument, sound, or chord group. There is a kangaroo theme to this software.
