Kangas Sound Editor QI lets you synthesize sound effects and music effectively from scratch. The QI variant of the Kangas Sound Editor has its own internal database engine (HSQLDB), unlike the regular Kangas Sound Editor, which needs MySQL Server to be separately downloaded and installed. 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.
