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.
GLD-fork is a fork of the GLD program by Salim Gasmi. The fork has been made because the original project has been dead for many years, and some new featured were needed.

GLD-fork can easily be combined with other (more resource consuming) tools to build anti-spam protection.
