Some Elvira 1 music tracks would not loop properly. These tracks make use of
the loop event, which stores the position in the MIDI stream where the parser
will later loop to. An event is optionally preceded by a delta, as indicated by
the _noDelta property of the parser. However, when looping, this flag was not
set to the state matching the event after the loop point. This would sometimes
cause the parser to interpret a MIDI event as a delta, which would break the
parsing.
This is fixed by storing the _noDelta flag with the loop data and setting it
to the stored value when looping.
This adds support for the AdLib and MT-32 sound effects in Elvira 2 and
Waxworks. It adds an option to the UI to toggle between sampled and
synthesized SFX. It also adds the following enhancements:
- AdLib OPL3 mode for Elvira 2, Waxworks and Simon 1 floppy demo. This can be
selected using a new UI option.
- Mixed AdLib/MIDI mode for Elvira 2 and Waxworks.
- Implemented "monophonic chords", a feature of the original MIDI code which
would play only the highest note of a chord on AdLib. Most noticable in the
Waxworks music.
- Added UI option to select Simon 1 DOS music tempos.
- Rewrite of the AdLib and MT-32 drivers to remove duplication and make use of
features of the standard multisource drivers.
- Refactored MidiPlayer to standardize interface and remove code moved to the
drivers and parsers.
- both known variants are supported (INSTR.DAT + MUSIC.DRV)
- INSTR.DAT/MUSIC.DRV holds channel mapping, instrument mapping, etc.
- fixed bug inside S1D MidiParser, that ruined some instrument changes
0xFC header was seen as 2 byte header, but it's 4 bytes in Elvira 2
and 5 bytes in Waxworks / Simon 1 demo
- dynamic channel allocation for the MUSIC.DRV adlib driver is not
implemented atm, simply because at least the demos of Waxworks and
Simon 1 do not use this feature
- sound effects of Waxworks are not implemented atm
- note: the game "Altered Destiny" uses Accolade INSTR.DAT variant too
