| byte * | _tracks [MAXIMUM_TRACKS] |
| Multi-track MIDI formats are supported, up to 120 tracks. | |
| byte | _numTracks |
| Count of total tracks for multi-track MIDI formats. 1 for single-track formats. | |

| bool | _abortParse |
| If a jump or other operation interrupts parsing, flag to abort. | |
| bool | _jumpingToTick |
| True if currently inside jumpToTick. | |
| bool | _doParse |
| True if the parser should be parsing; false if it should not be active. | |
| bool | _pause |
| True if the parser has paused parsing. | |
