This adds support for the OPL rhythm mode to the AdLib multisource MIDI driver.
Some games (f.e. Simon 1) use this to generate the rhythm sounds of their music.
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.
The music playing at the game over screen would only play once and send MIDI
CC 18 messages, which are not defined in the MIDI standard. I added looping and
removed the non-standard MIDI messages to prevent possible compatibility
issues.
The music for cutscenes and for the game over screen had some strange volume
differences compared to the original interpreter which seem to be caused by a
bug in the original interpreter where volume adjustments from sound effects
would carry over into the music. I've added a note to explain this difference.
The animation that plays when you fall through the sewage chute near the start
of the game had some issues. Fades were missing at several points, the middle
part of the animation was played only once and too slow, and when skipping the
animation it would only skip the currently playing part instead of the entire
animation.
To fix these issues, I've added an option to AnimationSequence to loop the
animation a number of times.
Some tracks in LotT contain channel aftertouch events. These are not supported
by the MT-32 and the original interpreter does not send them to the MIDI
device. This change removes them from the MIDI output.
When pausing the game by bringing up the ScummVM menu, the MIDI notes would
hang. I've added code to pause and resume the active MIDI parsers, which stops
the active notes.
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.
The original interpreter sends out a SysEx to turn off the MT-32 reverb when
opening a door while outside. This does not seem to work properly in the
original interpreter, and it is unclear what the developer's intentions were
with this function, so I've added a comment and removed the functionality.
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.
The LotT MT-32 MIDI data specifies a velocity value for the Note Off events,
but this is not sent to the MT-32 by the original interpreter. This removes the
velocity from the Note Off events, so it matches the MIDI output of the
original interpreter.
ScummVM would add one to the number of MIDI channels specified for a sound
resource, but this does not match the actual number of channels used in the
MIDI data. Additionally, it would not take into account the fact that the first
MIDI channel used in the MT-32 data is channel 1 instead of 0. This change
corrects this; the MIDI channels used now match those of the original
interpreter.
Lure of the Temptress defines a volume level for each sound resource. This is a
byte value which can increase or decrease the volume of the sound as specified
in the MIDI data (80h is the neutral value). The original interpreter applies
this as a scaling factor to the Note On velocity for the MT-32. ScummVM used it
to scale the MIDI volume control change values instead, causing incorrect
volume levels.
This change applies the sound resource volume to note velocity instead, which
results in the same volume as the original interpreter. I've left the old
method in place for AdLib, because I'm not sure how the original interpeter
handles sound resource volume in this case.
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.
Some music tracks (f.e. the 2nd introduction track) do not properly set the
volume on all channels and rely on the volume set by the previous track.
ScummVM would reset the volume on all channels between tracks, which caused
wrong volumes on some channels. I've removed this.
The MIDI player remaps the channels in the MIDI data to the available channels
on the MIDI device. In case of MT-32 music, this does not work, because the
percussion channel gets remapped to an instrument channel. The original
interpreter does not remap the channels of the music at all.
I've turned off channel remapping for all MT-32 MIDI data marked as music.
This fixes tons of warnings with clang from a recent xcode version on
macOS (and possibly other systems) complaining that an instantiation
of _singleton is required but no definition is available.
find -name '*.h' -or -name '*.cpp' | xargs sed -r -i 's@\(([A-Za-z0-9]+)\*\)@(\1 *)@g'
This seems to have caught some params as well which is not undesirable IMO.
It also caught some strings containing this which is undesirable so I
excluded them manually. (engines/sci/engine/kernel_tables.h)
Silences the clang warning:
static data member specialization of '_singleton' must
originally be declared in namespace 'Common'; accepted as a C++0x
extension [-Wc++0x-extensions]
Wrapping "namespace Common {}" around the macro assignment causes clang
to complain about a spurious semicolon, and removing the semicolon at
the end of the macro causes some editors to misbehave.
Changing the requirement of using the macro in one namespace (the
global) to another (Common) seems a small price to pay to
silence a warning.
The regression affected AGOS and maybe some others; specifically,
the real MidiDriver would have been deleted twice -- I previously
missed that the Engine instances takes care of freeing the real
MidiDriver, not the MidiPlayer wrapping it.
This commit should clarify the ownership of the real MidiDriver for
most pseudo MidiDrivers.
Many engines follow the advice in audio/midiparser.h and create a
"pseudo-MidiDriver" subclass. But MidiParser really only needs a tiny
subset of the MidiDriver capabilities, namely those found in
MidiDriver_BASE. So we try to subclass from that whenever possible; this
allows us to remove many stub methods, and enables further future
simplifications.
This in turn enables modifying MidiDriver_MPU401::close() to allow
it to be called on a midi driver that has not yet been opened.
The specific issue that triggered me to make these changes was a
crash-upon-quit in HUGO, caused by it instantiating a midi driver,
then encountering an error (missing hugo.dat) *before* having
opened the new midi driver; the general cleanup code then tries
to close the (not yet opened) midi driver -> kaboom
Also fixed some engines which were leaking MidiDriver instances.
This makes it possible to write
DECLARE_SINGLETON(foo);
instead of
DECLARE_SINGLETON(foo)
without causing a warning about an extra semicolon.
The extra semicolon helps some editors at parsing the C++ code.

This is currently done in the engine code. I adapted AGI, AGOS, DRACI,
GROOVIE, LURE, MADE, QUEEN, SAGA, SKY, TINSEL and TOUCHE to send a reset
device on startup. The sound output still works fine (started up a game
from every engine), so this should hopefully not introduce any regressions.
As far as I can tell it seems that SCUMM does send a proper device reset, so
I did not touch it. KYRA only sends a proper reset for MT-32 currently. I am
not sure about SCI though.
This fixes bug #3066826 "SIMON: MIDI notes off when using RTL after SCI".

We need to use a namespace Common { } there to make strict C++ compilers
like clang++ and comeau happy. I also added a slight comment about why
that is needed to the macro definition and a note that you need to use
it from the global namespace.
