IABC is a free music notation program based on the ABC programming language. It uses the ABC music notation language to produce high-quality graphical notation or MIDI output. The music notation and the ABC notation can be updated in real-time, making the construction of tunes using the ABC language hassle-free (or at least hassle-resistant).
The goal of iabc is to incorporate the functionality of a wide variety of 'filter' tools, such as abc2ps or abc2midi, into one easy-to-use application. My goal was to not make it the 'front end' (or worse, 'back end') of any other program, no matter how useful. Nothing against the text-based tools, but the technology has evolved to a point that it should be possible to provide free music software the is both graphical and robust.
Here are some key features of "IABC":
· Graphical Display of music
· Music printing
· MIDI output
· Multi-voice abc
· Cut/paste/undo/transpose edit functions
