- Made the maximum number of TiMidity voices configurable through the
timidity_voices cvar. - Added stats lines for the OPL and Timidity MIDI devices. - Completely changed the way TiMidity volume calculations are done. It should now be extremely close to the output a real GUS would produce with its official MIDI player (excepting where TiMidity normalizes sample volumes). The new equations more closely match what is specified by the DLS and SF2 specs (but not quite), so I presume it's also more musically correct than what TiMidity (and TiMidity++) do. SVN r925 (trunk)
