Both means to calculate `diff` are essentially equal because
wraparound of unsigned integers is well-defined and does what
the 'else' branch is simulating manually. Because of this,
gcc complains when compiling with -Wduplicated-branches.
Fix the "MI2: Two soundtracks playing at once" bug from the bug tracker.
It's triggered when the player enters the kiosk for the second time and
leaves before tune 113 is started.
Fix the "MI2: Two soundtracks playing at once" bug from the forum. It's
triggered when the player is moving faster then the scripts expect causing
the "stop tune 117" command be executed before the start of the tune.
Effectily creating a hanging tune 107.
This patch kills the tune when this sitation is detected.
1. Remove _sc55 bool. All Roland GS-capable devices have MT-32 sound/drum maps, so they should always be used when _enable_gs is set.
2. Always enable _native_mt32 if Roland GS mode is selected. I don't know why I never did this originally, since _enable_gs is automatically disabled for SCUMM v6+ games that use General MIDI tracks instead of MT-32 music.
3. Set master tune for GS devices to 442.0kHz. This is the master tune setting for the MT-32.
For old savegames, we now use a "dummy" iMUSE objet to skip the old
iMUSE save state. I had hoped to be able to do this without making
any changes to the iMUSE code itself, but I was unable to.
Also added note about how the save state for the new music will not
quite work if the mixer output rate changes. Personally, I'm not
too worried about that. It breaks, but it shouldn't break badly.
This should help identify incorrect dumps/file naming like what (probably)
happened in bug #3570973
"FOA: Doesn't start anymore after adding Mac sound support".
Formerly we ever only used the lower 4 bit of the priority setting for a new
part. The original used a full 8 bit setting though (based on the Indy4 PC
Speaker output driver). This fixes missing notes in the Indy4 intro with PC
Speaker output.
This might affect other outputs too! And could cause regressions in case other
outputs implemented priority settings differently.
Now we only output a new frequency if a new channel was selected or a new
output frequency has to be send. This makes the sound much more like in
DOSBox. This is not present in the original, but since our timings are
different this should make up for that.
Albeit the code is marked as a hack inside the source, the original behaved
exaclty the same. If the code is removed the PC Speaker output will miss notes,
since unlike the original we only output to parts, which have an instrument set
up.
This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'
1) Don't skip transpose setting in sysex command 0. There are only a few sounds where this setting is used (mainly sfx).
2) Make MI2 and INDY4 read certain player start parameters from the sound resource. The start parameters usually match our default parameters (exception: e.g. LeChuck's Fortress). The use of these parameters has been dropped in DOTT (they use default parameters like we do).
This adds an extra detune parameter which is assigned via sysex code 0.
Most tracks don't use this (= assign a value of 0), so it isn't really a
very noticeable feature.
- Revert guesswork fix for bug #761637 which caused bug #1315950
- Add missing clear_queue() call to stopAllSounds_internal(). This is taken from INDY4 / MONKEY2 disasm. Someone with a SAMXMAX or DOTT disasm might want to check whether this is correct for these targets, too.
- Old FOA savegames saved after the Dr. Ubermann death scene (= during the ending sequence) will still be bugged, since the messed up imuse trigger/command queue gets restored from the savegame.
