 \caption{Example rhythm annotation \code{.rhy} file containing two bars of the Son Clave rhythm. The first is expressed as a note sequence with resolution of four ticks per quarternote; the second is the same rhythm expressed as a velocity sequence (see section~\ref{sec:background}).}

-Our \code{.rhy} annotation format is a light text syntax for descibing rhtyhm patterns directly in terms of note and velocity sequences (see Figure~\ref{ta:clave}).

+The MIDI file reader can open type 0 and type 1 standard MIDI files and select a given track to read rhythm from.  Notes with zero delta time between them are treated as the same event for the purposes of creating note sequences from the MIDI stream. Time signature and tempo events encoded in the MIDI stream are assumed to correctly describe those parameters of the recorded music so it is recommended that the user uses correctly annotated and quantised MIDI files.
 
 \subsection{Plugin architecture}
 The system architecture has been designed to allow new models to be added easily.   Models have a common interface, exposing a single function that will return the syncopation value for a bar of music.  Optional parameters may be supplied as a Python dictionary if the user wishes to specify settings different from the those given in the literature for a specific model.
