Toadflax
graphical front-end for editing/transposing abc music files
...It exists in two forms, Toadflax built using GTK and py_toadflax built using tkinter, the python window toolkit. It allows the user to load in abc music notation files and work on each one independently. The music is displayed on-screen, without needing to use a PostScript interpreter, making it a lightweight notation viewer. The Toadflax program uses a music renderer based on yaps, while py_toadflax uses the music renderer from the abcCairo project based on abcm2ps. The source can be hand-edited or transformed in various ways using an adaptation of the abc2abc program. ...
