SubtrackStatus	_subtracks [35]

Detailed Description

Maintains time and position state within a MIDI stream, or multiple parallel MIDI streams. A single Tracker struct is used by MidiParser to keep track of its current position(s) in the MIDI stream(s). The Tracker struct, however, allows alternative locations to be cached. See MidiParser::jumpToTick() for an example of tracking multiple locations within a MIDI stream. NOTE: It is important to also maintain pre-parsed EventInfo data for each subtrack in each Tracker location.
