* plugins (doom, midi, rockboy): don't use non-static inlineRafaël Carré2010-09-07
| | | | | | | some functions can be static -> static inline some functions are external and can't be inlined -> remove inline git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28019 a1c6a512-1295-4272-9138-f99709370657

Probably not a good idea for speed, but the order can be optimized more later. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15652 a1c6a512-1295-4272-9138-f99709370657

* MIDI: Allow seeking forward and backward using the left/right keys. ↵Stepan Moskovchenko2007-11-03
| | | | | | | | | | | | | Currently seeks in 5 second increments, but this can be set to any amount. Also implemented a counter for playing time, which can pretty easily be used to determine the length of the file, in seconds, before playing it. The time isn't displayed anywhere right now, but all this can be useful if this thing is turned into a codec, or at least gets a nice UI. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15418 a1c6a512-1295-4272-9138-f99709370657

* MIDI: Scale each instrument by a calibration value, since not all patches ↵Stepan Moskovchenko2007-10-17
| | | | | | | | | | | are at the same base volume. This should make some files sound more natural, without some instruments overpowering others. Ultimately, these values need to be moved to the config file, and the table should probably be put in IRAM or something. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15161 a1c6a512-1295-4272-9138-f99709370657

| | | | | | | | | | | | Added Karl Kurbjun's sound output patch, cleaned up some output. Main file is now midiplay.c, midi2wav is still in there for anyone who wants it. Set sampling rate to 22k, and increased note decay time. Reduced number of concurrent active voices and made new notes replace used voices if none are available. This makes lag less apparent. I really hope this wont go red. (turns around and runs) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9858 a1c6a512-1295-4272-9138-f99709370657
