2011-04-28JANITORIAL: Reduce header dependencies in shared codeOri Avtalion
Some backends may break as I only compiled SDL
2011-03-22AUDIO: Add pure virtual MidiDriver::isOpen() methodMax Horn
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.

2011-03-10ALSA: Work around a firmware bug in USB-MIDI cables.Johannes Schickel
Thanks to waltervn (and wjp) for their investigation on this and Walter's SCI specific workaround which I more or less just copied here so it will apply for all engines.
2011-03-10ALSA: Strip trailing spaces in device name.Johannes Schickel
This might fix odd problems when storing the device name in the config file, when the name ends with a space by chance.

2010-10-30ALL: Add code to help stop people from accidentally using "bad" APIsMax Horn
A new header file common/forbidden.h is included by scummsys.h and it re-#defines numerous symbols like fopen(), fread(), system(), etc. with garbage, in order to provoke compile errors in any code using them. If a .cpp file really *must* use any of these (e.g. because it is a backend file), then these redefinitions can be disabled by #defining FORBIDDEN_SYMBOL_ALLOW_ALL as the first thing in the .cpp file. Whenever this is done, an explanatory comment should be added. Note that this system cannot catch all "bad" usages (notably the Lua code in the sword25 engine), as it can only work if scummsys.h is included. svn-id: r53961
2010-07-27ALSA: Be more intelligent when picking MIDI portTorbjörn Andersson
Often, a client has more than one available port. Pick the first one that isn't already in use. For instance, on my computer client 17 is the "Emu10k1 WaveTable", and it has four available ports. If, say, aplaymidi is already playing on port 17:0, ScummVM will use port 17:1 instead. Otherwise the two programs will mess up each others instruments and controller settings. Of course, in reality I doubt that anyone will run two different MIDI playing applications at once. svn-id: r51380
2010-07-27ALSA: Tweak capability and type flags for the MIDI portTorbjörn Andersson
This keeps ScummVM's own port from being included in the list of available MIDI devices. svn-id: r51378
2010-07-27ALSA: Simplify device querying code.Johannes Schickel
Thanks to eriktorbjorn for some quick testing. svn-id: r51366
2010-07-20MIDI: Build and use ALSA driver if and only if USE_ALSA is definedMax Horn
svn-id: r51053
2010-07-19ALSA: Get ALSA port settings from the new device config settings.Torbjörn Andersson
This is also an attempt to make the transition from the old settings to the new ones a little less rough, by trying to put something sensible into the first device, which is what's used by default. Currently it prefers 17:x and 65:x since they're the old defaults, followed by 128:x since that's probably TiMidity. The old SCUMMVM_PORT environment variable still overrides any config settings. I haven't made up my mind whether or not that's a good idea, but at least it prints a warning message. TODO: The old 'alsa_port' setting is not handled. It should probably be used to set sensible defaults for the new settings, but I'm not sure where this should be done. TODO: The documentation will need to be updated, once everything is working the way it should. svn-id: r51019
2010-07-19SUBSYSTEM: ALSA music driverTorbjörn Andersson
We should probably open the sequencer the exact same way, both when opening the driver and when asking it for available MIDI devices. Not that I've been able to figure out the difference between "hw" and "default" from the fine ALSA manual... And I'm not sure we really need to try and keep compatibility with ancient (pre-0.9.0?) ALSA any longer... svn-id: r51014
2010-07-14If the ALSA driver hasn't been opened, closing it should do nothing. This keepsTorbjörn Andersson
ScummVM from crashing if, for instance, someone accidentally closes the driver twice. svn-id: r50870

2008-11-30- Extended MidiDriver::sysEx to allow 264 byte sysEx messagesJohannes Schickel
- Updated all drivers to allow 264+2 byte sysEx messages - Implemented sysEx processing for MT-32 for Kyra1 and HoF. MT-32 should now be working properly. svn-id: r35180
2008-11-05Turned enum PluginError into Common::Error, which in the future is to be ↵Max Horn
used in more places. Help with this is highly welcome svn-id: r34906
2008-08-05Committed my patch #2026097 ("ALSA: Try both 65:0 and 17:0 by default"), with aTorbjörn Andersson
slight modification to the README changes. (I don't know how to interpret all the output from aconnect, so I'm only documenting "the most important bit".) svn-id: r33648

formerly knowns as Gaim) does; added new (incomplete) COPYRIGHT file; updated copyright dates in a few spots svn-id: r27024
2007-02-16Unified how we deal with (and how we generate) MIDI sysex messages -- in ↵Max Horn
particular, we now always do so w/o framing the message (documented this with a Doxygen comment in the MidiDriver class) svn-id: r25630
2006-09-20Some updates (mostly guesswork) for the ALSA MIDI driver, mostly prompted byTorbjörn Andersson
Waxworks (Simon engine). See http://www.borg.com/~jglatt/tech/midispec.htm for reference. * Added case for Aftertouch (Key Pressure). * Changed Channel Pressure to flush the event immediatley. The message could apply to notes while they are playing. * Downgraded the error for unknown MIDI messages to a warning, and clarified it slightly. svn-id: r23949
