*
* There are 4 possible tracks, like: normal, tension, action, high action. Segment 0 has tracks'
* entry segments (where 1=first, right after segment 0), and each segment has a link point to next
* (or starting) segment of any of other tracks. Thus, follow point 1/2/3/4 to playtrack 1/2/3/4
* (points also loop back). It's designed to go smoothly between any tracks (1>3, 4>1, etc),
* so sometimes "step" segments (that aren't normally played) are used.
* If a track doesn't exist it may keep repeating silent segments, but still defines points.
*
* ex. sequence could go like this:
* (read segment 0 track1 entry): 1
* - track0: 1>2>3>4>5>6>7>8>1>2>3, then to track2 goes 3>15>9
* - track1: 9>10>11>12>13>14>9>10, then to track4 goes 10>33
* - track2: 33>34>35>36>30>31>32>33, then to track1 goes 33>3
* - track3: 3>4>5>6... (etc)
*
* Well make a sequence based on target subsong:
* - 1: tracks mixed with transitions, looping back to track1 (only first is used in .sch so we want all)
* - 2~5: track1~4 looping back to themselves
* - 6+: single segment (where 6=first segment) to allow free mixes
