Mutabor is a program that supports the live music with micro tones. It allows to play any pitches, even those which are not availlable on ordinary keyboards. An important application is the „just intonation“.

Mutabor uses its own musical language to describe pitches, (re)tunings and reactions to events (chords, keys, MIDI signals). Furthermore, MIDI ports, MIDI files, and GMN files can be used in the same manner, mixed and output.

Mutabor is a low-cost device, but its services in the area of intonation are still significantly beyond that which provides today's live equipment to musicians. It provides easy access to static and mutating tunings, can quickly switch between them, and allows the performer to experiment freely with them. So it is interesting for many users: for Musicians, who want to explore and compare the ancient tunings, in ear training, for music theory, as a tonal experimentation field for composers, and much more.

     keinstein - 2011-Dec-11 17:55   -   Mutabor
With the implementation of a new editor, all functions of Mutabor 3.0 should be availlable in 3.1. This is the time to change the status into beta. This means the software should be usable but might still contain some errors. The more people are using Mutabor, the more errors can be found and the faster the final release state can be reached.
