Detailed Description

Standard Midi File. Currently only tempo-based time of a given PPQN is supported.

For WRITING: this object specifically wraps a type0 file or a type1 file with only a single track. It has no support at this time for a type1 file with multiple tracks.

For READING: this object can read a single arbitrary track from a type1 file, or the single track of a type0 file. It has no support at this time for reading more than 1 track.
