+ We have the following information from Lars Christensen (lechimp) and
+ Jamieson Christian (jamieson630):
+
+ RESOURCE DATA
+ LE 2 bytes Resource size
+ 2 bytes Unknown
+ 2 bytes 'so'
+ 14 bytes Unknown
+ BE 2 bytes Instrument for Stream 1
+ BE 2 bytes Instrument for Stream 2
+ BE 2 bytes Instrument for Stream 3
+ BE 2 bytes Instrument for Stream 4
+ BE 2 bytes Instrument for Stream 5
+ BE 2 bytes Offset to Stream 1
+ BE 2 bytes Offset to Stream 2
+ BE 2 bytes Offset to Stream 3
+ BE 2 bytes Offset to Stream 4
+ BE 2 bytes Offset to Stream 5
+ ? bytes The streams
+
+ STREAM DATA
+ BE 2 bytes Unknown (always 1?)
+ 2 bytes Unknown (always 0?)
+ BE 2 bytes Number of events in stream
+ ? bytes Stream data
+
+ Each stream event is exactly 3 bytes, therefore one can
+ assert that numEvents == (streamSize - 6) / 3. The
+ polyphony of a stream appears to be 1; in other words, only
+ one note at a time can be playing in each stream. The next
+ event is not executed until the current note (or rest) is
+ finished playing; therefore, note duration also serves as the
+ time delta between events.
+
+ FOR EACH EVENTS
+ BE 2 bytes Note duration
+ 1 byte Note number to play (0 = rest/silent)
+
+ Oh, and quick speculation -- Stream 1 may be used for a
+ single-voice interleaved version of the music, where Stream 2-
+ 5 represent a version of the music in up to 4-voice
+ polyphony, one voice per stream. I postulate thus because
+ the first stream of the Mac Loom theme music contains
+ interleaved voices, whereas the second stream seemed to
+ contain only the pizzicato bottom-end harp. Stream 5, in this
+ example, is empty, so if my speculation is correct, this
+ particular musical number supports 3-voice polyphony at
+ most. I must check out Streams 3 and 4 to see what they
+ contain.
+
+ ==========
+
+ The instruments appear to be identified by their resource IDs:
+
+ 1000 Dual Harp
+ 10895 harp1
+ 11445 strings1
+ 11548 silent
+ 13811 staff1
+ 15703 brass1
