- Attempts to calculate the timings of the chord changes, instead of just extracting the chords from ABC files (which has been done long time ago by someone else).
- Midi files generated by abc2midi can be automatically included by the script in the final MMA output, via MMA’s MIDIinc command.
- MMA commands can be inserted directly in the ABC file using the command “%%X-MMA <mma command>”. Please see the included demo.abc for examples.
- Handles multi-song ABC files. Roll your own fakebook anyone? :-)

Frequently Asked Questions
- How do I insert MMA commands?
Use “%%X-MMA <mma command>” to directly insert MMA commands at the appropriate sections in the file (note: must be on a separate line). Please refer to the included demo.abc for examples.
- The included melody (from abc2midi) and the chords accompaniment are not aligned! The music has a pick-up measure.
Insert the “BeatAdjust” MMA command with the appropriate number of beats to offset after the pick-up measure. Please refer to the included demo.abc for examples.
- I get a run-time error with ABC files containing the “%%MIDI program” command.
Please download the latest version of MMA.
Notes / Disclaimers
- This is NOT a parser! I’m just using mostly string substitution to get the results I want. I’m too lazy to write a full abc parser. :-P
- I do not claim to handle all possible abc notation scenarios. There are features of abc notation which I don’t use, so I’m sure there are many cases which are broken.
- Finally, use at your own risk! I’m not responsible for any damages, blah blah… that may result from the use of this software.
