- simplified the sound font manager a bit. - allow the GUS to change sound fonts at run time. - implemented sound font manager support in the GUS synth. This works but also made me realize that the SF2 support of this synth has been rather broken, apparently forever.

Separate WildMidi mixing from event handling - In order to use ZDoom's own MIDI sequencer event handling must be completely separate from mixing, but WildMidi had them intertwined because it wasn't designed for external sequencers. - Also remove all 'long's defining the output buffers to avoid having something that's 32 bits wide on Windows and 64 bits wide on Linux.

Fix(?) dBm_pan_volume table - The missing comma on the first line of dBm_pan_volume's definition looked suspicious, so I checked the MIDI specification at http://www.midi.org/techspecs/rp36.php and found the equations there gave different dB values than were in the table. So I rebuilt it using the equation given there: 20*log (sin (Pi /2* max(0,CC#10 – 1)/126))

Import volume handling changes from current WildMidi git - Description there reads: > Major work done on “log” volumes. Calculations are now based on decibels.
2016-01-12 01:21:41 +00:00
- refactoring of WildMidi to have proper instrument management Not tested yet, it compiles but may not work as-is.
2019-09-25 15:27:10 +00:00
static const unsigned int freq_table[] = { 837201792, 837685632, 838169728,
- added WildMidi library sources - all converted to C++ so that they can later interface with ZDoom's own MIDI code. Also redid the file loading function to use ZDoom's FileReader instead of low level IO.

- refactoring of WildMidi to have proper instrument management Not tested yet, it compiles but may not work as-is.

- added WildMidi library sources - all converted to C++ so that they can later interface with ZDoom's own MIDI code. Also redid the file loading function to use ZDoom's FileReader instead of low level IO.

Separate WildMidi mixing from event handling - In order to use ZDoom's own MIDI sequencer event handling must be completely separate from mixing, but WildMidi had them intertwined because it wasn't designed for external sequencers. - Also remove all 'long's defining the output buffers to avoid having something that's 32 bits wide on Windows and 64 bits wide on Linux.
