Description: Software sound renderer (MIDI sequencer, MOD player)
 TiMidity++ is a very high quality software-only MIDI sequencer and MOD player.
 It uses sound fonts (GUS-compatible or SF2-compatible) to render MIDI files,
 which are not included in this package.

 * Plays MIDI files without any external MIDI instruments at all
 * Understands SMF, RCP/R36/G18/G36, MFI, RMI (MIDI)
 * Autodetects and supports GM/GS/XG MIDI
 * Understands MOD, XM, S3M, IT, 699, AMF, DSM, FAR, GDM, IMF, MED, MTM, STM,
   STX, ULT, UNI (MOD)
 * Does MOD to MIDI conversion (including playback)
 * Outputs audio into various audio file formats: WAV, au, AIFF, Ogg (Vorbis,
   FLAC, Speex)
 * Supports NAS, eSound, ARtS, JACK, ALSA and OSS drivers
 * Uses Gravis Ultrasound compatible patch files and SoundFont2 patch files as
   the voice data for MIDI instruments
 * Supports playing from archives (zip, lzh, tar...) and playing remote data
   from the network
 * Timidity++ can be used as an ALSA sequencer device

"It has been just so in all my inventions. The first step is an
intuition--and comes with a burst, then difficulties arise. This thing
gives out and then that--'Bugs'--as such little faults and
difficulties are called--show themselves and months of anxious
watching, study and labor are requisite before commercial success--or
failure--is certainly reached" -- Thomas Edison in a letter to
Theodore Puskas on November 18, 1878
