16d18c707a - Fixed: When note_on() is called and another copy of the same note is
already playing on the channel, it should stop it with finish_note(), not
  kill_note(). This can be clearly heard in the final cymbal crashes of
  D_DM2TTL where TiMidity cuts them off because the final cymbals are played
  with a velocity of 1 before the preceding cymbals have finished. (I wonder
  if I should be setting the self_nonexclusive flag for GUS patches to
  disable even this behavior, though, since gf1note.c doesn't turn off
  duplicate notes.)
- Changed envelope handling to hopefully match the GUS player's. The most
  egregious mistake TiMidity makes is to treat bit 6 as an envelope enable
  bit. This is not what it does; every sample has an envelope. Rather, this
  is a "no sampled release" flag. Also, despite fiddling with the
  PATCH_SUSTAIN flag during instrument loading, TiMidity never actually
  used it. Nor did it do anything at all with the PATCH_FAST_REL flag.

03b4f71edf - Reduced the range that area sounds require to interpolate between 2D and
3D panning.
- The listener's velocity is now set at 0 for the sound engine. The player
  moves so fast that you can hear the doppler shift just by running around,
  otherwise.
- Changed the sound code so that all sounds that start playing on a single
  tic actually start playing at the exact same sample position.

effe9427fd - Added the writewave command to write the internal TiMidity's output to a
wave file.
- Changed the default channel velocity for MUS files from 64 to 100 to
  better match apparent MIDI practice. (Would like to know what this is
  supposed to be.)
- Changed the mus2midi channel assignments to match the internal player's.
- Fixed: apply_envelope_to_amp() should clamp the mix levels to 0.

f6866df0e6 - 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.

9450db3cec parameters. These seem to be used primarily to restrict percussion
instruments to specific notes.
- Changed note velocity to not use the volume curve in recompute_amp(), since
  this sounds closer to TiMidity++, although I don't believe it's correct
  MIDI behavior. Also changed expression so that it scales the channel volume
  before going through the curve.
- Reworked load_instrument to be less opaque.
- Went through the TiMidity code and removed pretty much all of the SDL_mixer
  extensions. The only exception would be kill_others(), which I reworked
  into a kill_key_group() function, which should be useful for DLS
  instruments in the future.

0d18580ff0 - Fixed: Timidity::Channel::mono, rpn, and nrpn were not initialized. In
particular, this meant that every channel was almost certainly in mono mode,
  which can sound pretty bad if the song isn't meant to be played that way.
- Added bank numbers to the MIDI precaching for Timidity, since I guess I do
  need to care about banks, if even the Duke MIDIs use various banks.
- Fixed: snd_midiprecache only exists in Win32 builds, so gameconfigfile.cpp
  shouldn't unconditionally link against it.
- Fixed: pre_resample() was still disabled, and it left two samples at the end
  of the new wave data uninitialized.

10c0d67b78 - Changed the MIDIStreamer to send the all notes off controller to each
channel when restarting the song, rather than emitting a single note off
  event which only has a 1 in 127 chance of being for a note that's playing
  on that channel. Then I decided it would probably be a good idea to reset
  all the controllers as well.
- Increasing the size of the internal Timidity stream buffer from 1/14 sec
  (copied from the OPL player) improved its sound dramatically, so apparently
  Timidity has issues with short stream buffers. It's now at 1/2 sec in
  length. However, there seems to be something weird going on with
  corazonazul_ff6boss.mid near the beginning where it stops and immediately
  restarts a guitar on the exact same note.
- Added a new sound debugging cvar: snd_drawoutput, which can show various
  oscilloscopes and spectrums.
- Internal TiMidity now plays music.
- Changed the progdir global variable into an FString.
