The first track in the LotT introduction fades out before the second track
starts. The fade-out is implemented by reducing the velocity of the new notes
that are being played. Because this does not affect notes that are already
playing, the fade-out effect is not very good. I've replaced this by a fade-out
using MIDI channel volume.
This fixes several issues with the introduction animation:
- The timing of the various parts of the introduction did not match the timing
of the original interpreter. The music did not properly match the images and
the last section was completely missing. I've adjusted the timing to beter
match the original interpreter.
- The VGA palette of the first text screens was broken and would display them
as completely white. I've added a patch to add the colors of the palette of the
following text screens.
- The animation of the soldiers approaching each other would fade out on the
original interpreter. I've added this.
- The images of the battle sequence would fade out on the EGA version. This
does not match the original interpreter and has been removed.
This change adds the MT-32/GM multisource MidiDriver to LotT. This adds the
following functionality:
- MT-32 initialization using the SysEx queue. ScummVM will remain responsive
while the SysExes are sent and the user can abort the process when skipping the
introduction or quitting the game.
- Use of Roland GS MT-32 instrument mapping.
It also allows for a proper implementation of music fade-outs. Some
functionality previously implemented in SoundManager is now done by the driver.
When sending SysEx data to the MT-32, the game blinks an icon in the lower left
corner of the screen. This change adds that icon. It is stored in the
executable, so I added code to create_lure_dat to extract the icon and add it
to the ScummVM data file. The new version of this file is now required to run
the game.
Some sound effects in LotT loop, like the thunderstorm in the beginning of the
game. This is indicated by the high bit of the sound number. This change adds
support for these looping sound effects.
Distinction between music and SFX was made based on the most significant bit in
the sound number byte. This does not accurately reflect which MIDI sequences
are music or a sound effect.
Instead, I've added a flag which can be passed to
SoundManager::musicInterface_Play to indicate whether the sound is music or a
sound effect. All music is started from hard-coded animation sequences, so this
flag can be passed from ScummVM code when appropriate.
