Mutabor is a program that allows you to perform and compose microtonal music using a normal MIDI keybord and normal MIDI equipment. Its powerful description language is intended to allow permanent retunings and complex tuning logic. One application is just tuning. Mutabor has been used for this purpose to make available all pitches that can be reached by stacking perfect thirds and perfect fifths. The stable version 3.0x is available in German only and runs under Windows and Wine. The unstable branch can be accessed via CVS (but build bugs should be expected) or downloaded from the Berlios developer site.
Release Notes: This release fixed slow MIDI playback on Windows, crashes due to memory corruption, and corrupted help files (only important in German). Multithreaded file players are now supported. They are not yet perfect and may contain race conditions. A major code restructuring was undertaken, and first steps were made towards an automated test system.
