This module handles encoding and decoding about SMF. This package includes MML (a simple musical notation language), which is an example of application.

Additional features: STT (a dialect of Masui's onomatopoeic notation Sutoton), Some stream editing (Quantize, Shuffle, Groove, Velocity compressor, etc), Morse encode, Import/Export as plain text and XML, play with spkr(4), Export as .wav (very slow and very low-fi).

Note: Some parts of the specification were changed in 0.15. Please see manual. This module's core works fine with only ruby standard environment. But some code depend rb-gsl and ruby-bsearch. They are optional.
