More sophisticated ABC notation support.
More sophisticated ABC notation support.

Support for key signatures, measures with persistent accidentals,
ties, and staccato. For example, the following uses two stacattos
and two ties, to play c# three times and c natural once:

play '^c.cc-|^c.=cc-|c'

Follows the ABC standard: dot before a note is stacatto;
dash after a letter is a tie; vertical bar is a measure bar.
