* MIDI: Increase percision of synthesizer by a factor of 4 - makes certain ↵Stepan Moskovchenko2007-11-17
| | | | | | | | | | parts (guitar bends, mostly) sound more natural. Also, completely rearrange the order of operations in the delta computation. Had to use long longs. 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: Improve seeking (especially near the end of the file) by disabling ↵Stepan Moskovchenko2007-11-03

* 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

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
