283 * output stream. The copy to buffer is performed once, then each effect
284 * function performs on the output of the previous effect. Understand that
285 * this extra copy to a buffer is not performed if there are no effects
286 * registered for a given chunk, which saves CPU cycles, and any given
287 * effect will be extra cycles, too, so it is crucial that your code run
288 * fast. Also note that the data that your function is given is in the
289 * format of the sound device, and not the format you gave to Mix_OpenAudio(),
290 * although they may in reality be the same. This is an unfortunate but
291 * necessary speed concern. Use Mix_QuerySpec() to determine if you can
292 * handle the data before you register your effect, and take appropriate
293 * actions.
294 * You may also specify a callback (Mix_EffectDone_t) that is called when
295 * the channel finishes playing. This gives you a more fine-grained control
296 * than Mix_ChannelFinished(), in case you need to free effect-specific
297 * resources, etc. If you don't need this, you can specify NULL.
298 * You may set the callbacks before or after calling Mix_PlayChannel().
299 * Things like Mix_SetPanning() are just internal special effect functions,
300 * so if you are using that, you've already incurred the overhead of a copy
301 * to a separate buffer, and that these effects will be in the queue with
302 * any functions you've registered. The list of registered effects for a
303 * channel is reset when a chunk finishes playing, so you need to explicitly
304 * set them with each call to Mix_PlayChannel*().
305 * You may also register a special effect function that is to be run after
306 * final mixing occurs. The rules for these callbacks are identical to those
307 * in Mix_RegisterEffect, but they are run after all the channels and the
308 * music have been mixed into a single stream, whereas channel-specific
309 * effects run on a given channel before any other mixing occurs. These
310 * global effect callbacks are call "posteffects". Posteffects only have
311 * their Mix_EffectDone_t function called when they are unregistered (since
312 * the main output stream is never "done" in the same sense as a channel).
313 * You must unregister them manually when you've had enough. Your callback
314 * will be told that the channel being mixed is (MIX_CHANNEL_POST) if the
315 * processing is considered a posteffect.
316 *

12 # These exist entirely to fool aclocal when bootstrapping libtool.
13 #
14 # In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
15 # which have later been changed to m4_define as they aren't part of the
16 # exported API, or moved to Autoconf or Automake where they belong.
17 #
18 # The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
19 # in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
20 # using a macro with the same name in our local m4/libtool.m4 it'll
21 # pull the old libtool.m4 in (it doesn't see our shiny new m4_define
22 # and doesn't know about Autoconf macros at all.)
23 #
24 # So we provide this file, which has a silly filename so it's always
25 # included after everything else. This provides aclocal with the
26 # AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
27 # because those macros already exist, or will be overwritten later.
28 # We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
29 #
30 # Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
31 # Yes, that means every name once taken will need to remain here until
32 # we give up compatibility with versions before 1.7, at which point
33 # we need to keep only those names which we still refer to.

7905 # These exist entirely to fool aclocal when bootstrapping libtool.
7906 #
7907 # In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
7908 # which have later been changed to m4_define as they aren't part of the
7909 # exported API, or moved to Autoconf or Automake where they belong.
7910 #
7911 # The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
7912 # in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
7913 # using a macro with the same name in our local m4/libtool.m4 it'll
7914 # pull the old libtool.m4 in (it doesn't see our shiny new m4_define
7915 # and doesn't know about Autoconf macros at all.)
7916 #
7917 # So we provide this file, which has a silly filename so it's always
7918 # included after everything else. This provides aclocal with the
7919 # AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
7920 # because those macros already exist, or will be overwritten later.
7921 # We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
7922 #
7923 # Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
7924 # Yes, that means every name once taken will need to remain here until
7925 # we give up compatibility with versions before 1.7, at which point
7926 # we need to keep only those names which we still refer to.
7927
7928 # This is to help aclocal find these macros, as it can't see m4_define.

1479 Usage: $0 [OPTION]... [VAR=VALUE]...
1480
1481 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1482 VAR=VALUE. See below for descriptions of some of the useful variables.
1483
1484 Defaults for the options are specified in brackets.
1485
1486 Configuration:
1487 -h, --help display this help and exit
1488 --help=short display options specific to this package
1489 --help=recursive display the short help of all the included packages
1490 -V, --version display version information and exit
1491 -q, --quiet, --silent do not print \`checking ...' messages
1492 --cache-file=FILE cache test results in FILE [disabled]
1493 -C, --config-cache alias for \`--cache-file=config.cache'
1494 -n, --no-create do not create output files
1495 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1496
1497 Installation directories:
1498 --prefix=PREFIX install architecture-independent files in PREFIX
1499 [$ac_default_prefix]
1500 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1501 [PREFIX]
1502
1503 By default, \`make install' will install all the files in
1504 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1505 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1506 for instance \`--prefix=\$HOME'.
1507
1508 For better control, use the options below.

1606 Some influential environment variables:
1607 CC C compiler command
1608 CFLAGS C compiler flags
1609 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1610 nonstandard directory <lib dir>
1611 LIBS libraries to pass to the linker, e.g. -l<library>
1612 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1613 you have headers in a nonstandard directory <include dir>
1614 CPP C preprocessor
1615 PKG_CONFIG path to pkg-config utility
1616 SDL_CFLAGS C compiler flags for SDL, overriding pkg-config
1617 SDL_LIBS linker flags for SDL, overriding pkg-config
1618 MODPLUG_CFLAGS
1619 C compiler flags for MODPLUG, overriding pkg-config
1620 MODPLUG_LIBS
1621 linker flags for MODPLUG, overriding pkg-config
1622 OPUSFILE_CFLAGS
1623 C compiler flags for OPUSFILE, overriding pkg-config
1624 OPUSFILE_LIBS
1625 linker flags for OPUSFILE, overriding pkg-config
1626
1627 Use these variables to override the choices made by `configure' or to help
1628 it to find libraries and programs with nonstandard names/locations.

src/codecs/timidity/CHANGES less more
0 This version of TiMidity should contain all the fixes from the
1 September 25 2003 SDL_mixer CVS snapshot. In addition, I've made some
2 changes of my own, e.g.:
3
4 * All file access is done through SDL_RWops. This means the MIDI
5 stream no longer has to be a file. (The config file and instruments
6 still have to be though.)
7
8 * Replacing of TiMidity's endian-handling with SDL's.
9
10 * Removal of much unused or unnecessary code, such as
11
12 + The "hooks" for putting a user interface onto TiMidity.
13 + The antialias filter. It wasn't active, and even at 4 kHz I
14 couldn't hear any difference when activating it.
15 + Removed all traces of LOOKUP_HACK and LOOKUP_INTERPOLATION.
16 According to the code comments they weren't very good anyway.
17 ("degrades sound quality noticeably"). I also removed the
18 disclaimer about the "8-bit uLaw to 16-bit PCM and the 13-bit-PCM
19 to 8-bit uLaw tables" disclaimer, since I believe those were the
20 tables I removed.
21 + Removed LOOKUP_SINE since it was already commented out. I think we
22 can count on our target audience having math co-processors
23 nowadays.
24 + Removed USE_LDEXP since it wasn't being used and "it doesn't make
25 much of a difference either way".
26 + Removed decompress hack from open_file() since it didn't look very
27 portable.
28 + Removed heaps of unnecessary constants.
29 + Removed unused functions.
30 + Assume that LINEAR_INTERPOLATION is always used, so remove all
31 code dealing with it not being so. It's not that I think the
32 difference in audio quality is that great, but since it wouldn't
33 compile without code changes I assume no one's used it for quite
34 some time...
35 + Assume PRECALC_LOOPS is always defined. Judging by the comments it
36 may not make much of a difference either way, so why maintain two
37 versions of the same code?
38
39 * Moving several static globals into the MidiSong struct. This
40 includes sample rate, formate, etc. which are now all per-song.
41
42 * Moved some typedefs (e.g. MidiSong) to timidity.h for easy inclusion
43 into the MIDI decoder.
44
45 * Added free_pathlist().
46
47 * Replaced TiMidity's own 8, 16 and 32-bit types with SDL's.
48
49 * Made TiMidity look for its configuration file in both /etc and
50 /usr/local/lib/timidity. (Windows version remains unchanged.)
51
52 * Timidity_PlaySome() now takes three arguments. A MidiSong, a decode
53 buffer and decode buffer size in bytes. (MidiSong is a new argument,
54 and buffer size used to be in samples.)
55
56 In addition, it will return the number of bytes decoded.
57
58 * Added Timidity_Exit().
59
60 * Removed Timidity_Stop() and Timidity_Active(). Stopping playback
61 should be handled by SDL_sound, and Timidity_PlaySome() will return
62 0 when the MIDI stream is finished.
63
64 * Modified the ToneBank stuff to allow some data to be shared between
65 MidiSongs.
66
67 * The following files have been removed: controls.c, controls.h,
68 filter.c, filter.h, sdl_a.c, sdl_c.c
69
70 * config.h has been renamed as options.h to avoid confusion with the
71 automatically generated config.h for SDL_sound.
72
73 * Added support for loading DLS format instruments:
74 Timidity_LoadDLS(), Timidity_FreeDLS(), Timidity_LoadDLSSong()
75
76 * Added Timidity_Init_NoConfig()

7 Frequently Asked Questions with answers:
8
9 --------------------------------------------------------------------------
10 Q: What is it?
11
12 A: Where? Well Chris, TiMidity is a software-only synthesizer, MIDI
13 renderer, MIDI to WAVE converter, realtime MIDI player for UNIX machines,
14 even (I've heard) a Netscape helper application. It takes a MIDI file
15 and writes a WAVE or raw PCM data or plays it on your digital audio
16 device. It sounds much more realistic than FM synthesis, but you need a
17 ~100Mhz processor to listen to 32kHz stereo music in the background while
18 you work. 11kHz mono can be played on a low-end 486, and, to some, it
19 still sounds better than FM.
20
21 --------------------------------------------------------------------------
22 Q: I don't have a GUS, can I use TiMidity?
23
24 A: Yes. That's the point. You don't need a Gravis Ultrasound to use
25 TiMidity, you just need GUS-compatible patches, which are freely
26 available on the Internet. See below for pointers.
27
28 --------------------------------------------------------------------------
29 Q: I have a GUS, can I use TiMidity?
30
31 A: The DOS port doesn't have GUS support, and TiMidity won't be taking
32 advantage of the board's internal synthesizer under other operating
33 systems either. So it kind of defeats the purpose. But you can use it.
34
35 --------------------------------------------------------------------------
36 Q: I tried playing a MIDI file I got off the Net but all I got was a
37 dozen warnings saying "No instrument mapped to tone bank 0, program
38 xx - this instrument will not be heard". What's wrong?
39
40 A: The General MIDI standard specifies 128 melodic instruments and
41 some sixty percussion sounds. If you wish to play arbitrary General
42 MIDI files, you'll need to get more patch files.
43
44 There's a program called Midia for SGI's, which also plays MIDI
45 files and has a lot more bells and whistles than TiMidity. It uses
46 GUS-compatible patches, too -- so you can get the 8 MB set at
47 ftp://archive.cs.umbc.edu/pub/midia for pretty good GM compatibility.
48
49 There are also many excellent patches on the Ultrasound FTP sites.
50 I can recommend Dustin McCartney's collections gsdrum*.zip and
51 wow*.zip in the "[.../]sound/patches/files" directory. The huge
52 ProPats series (pp3-*.zip) contains good patches as well. General
53 MIDI files can also be found on these sites.
54
55 This site list is from the GUS FAQ:

72
73 --------------------------------------------------------------------------
74 Q: Some files have awful clicks and pops.
75
76 A: Find out which patch is responsible for the clicking (try "timidity
77 -P<patch> <midi/test-decay|midi/test-panning>". Add "strip=tail" in
78 the config file after its name. If this doesn't fix it, mail me the
79 patch.
80
81 --------------------------------------------------------------------------
82 Q: I'm playing Fantasie Impromptu in the background. When I run Netscape,
83 the sound gets choppy and it takes ten minutes to load. What can I do?
84
85 A: Here are some things to try:
86
87 - Use a lower sampling rate.
88
89 - Use mono output. This can improve performance by 10-30%.
90 (Using 8-bit instead of 16-bit output makes no difference.)
91
92 - Use a smaller number of simultaneous voices.
93
94 - Make sure you compiled with FAST_DECAY enabled in options.h
95
96 - Recompile with an Intel-optimized gcc for a 5-15%
97 performance increase.

9 GNU GPL, (2) the GNU LGPL, or (3) the Perl Artistic License.

13 This is the README file for TiMidity v0.2i
14
15 TiMidity is a MIDI to WAVE converter that uses Gravis
16 Ultrasound(*)-compatible patch files to generate digital audio data
17 from General MIDI files. The audio data can be played through any
18 sound device or stored on disk. On a fast machine, music can be
19 played in real time. TiMidity runs under Linux, FreeBSD, HP-UX, SunOS, and
20 Win32, and porting to other systems with gcc should be easy.
21
22 TiMidity Features:
23
24 * 32 or more dynamically allocated fully independent voices
25 * Compatibility with GUS patch files
26 * Output to 16- or 8-bit PCM or uLaw audio device, file, or
27 stdout at any sampling rate
28 * Optional interactive mode with real-time status display
29 under ncurses and SLang terminal control libraries. Also
30 a user friendly motif interface since version 0.2h
31 * Support for transparent loading of compressed MIDI files and
32 patch files
33
34 * Support for the following MIDI events:
35 - Program change
36 - Key pressure
37 - Channel main volume
38 - Tempo
39 - Panning
40 - Damper pedal (Sustain)
41 - Pitch wheel
42 - Pitch wheel sensitivity
43 - Change drum set
44
45 * TiMidity requires sampled instruments (patches) to play MIDI files. You
46 should get the file "timidity-lib-0.1.tar.gz" and unpack it in the same
47 directory where you unpacked the source code archive. You'll want more
48 patches later -- read the file "FAQ" for pointers.
49
50 * Timidity is no longer supported, but can be found by searching the web.

src/codecs/timidity/TODO less more
0 * I don't like the indentation style at all, but for the most part
1 I've left it alone.
2
3 * Much of the code looks ugly to me.
4
5 * The return value from SDL_RWread() is checked inconsistenly.
6
7 * Group the members of MidiSong into logical units, i.e. structs?
8
9 * The debug messages are probably a bit too noisy. I've removed one
10 particularly annoying one, but...
11
12 Some of them should be turned into error messages instead.
13
14 * Can the instrument handling be made more efficient? At the moment
15 different MidiSongs may separately load the same instrument.
16
17 Note that the MidiSong's audio format affects how the instrument is
18 loaded, so it's not as easy as just letting all MidiSongs share tone
19 and drum banks.
20
21 At the moment they do share the data that is simply read from the
22 config file, but that's just a quick hack to avoid having to read
23 the config file every time a MIDI song is loaded.
24
25 * Check if any of MidiStruct's members can safely be made into static
26 globals again.
27
28 * TiMidity++ adds a number of undocumented (?) extensions to the
29 configuration syntax. These are not implemented here. In particular,
30 the "map" keyword used by the "eawpats".
31
32 * The other decoders generally only read as much of the file as is
33 necessary. Could we do that in this decoder as well? (Currently it
34 seems to convert the entire file into MIDI events first.)
35
36 * Can it be optimized?

timidity/CHANGES less more
0 This version of TiMidity should contain all the fixes from the
1 September 25 2003 SDL_mixer CVS snapshot. In addition, I've made some
2 changes of my own, e.g.:
3
4 * All file access is done through SDL_RWops. This means the MIDI
5 stream no longer has to be a file. (The config file and instruments
6 still have to be though.)
7
8 * Replacing of TiMidity's endian-handling with SDL's.
9
10 * Removal of much unused or unnecessary code, such as
11
12 + The "hooks" for putting a user interface onto TiMidity.
13 + The antialias filter. It wasn't active, and even at 4 kHz I
14 couldn't hear any difference when activating it.
15 + Removed all traces of LOOKUP_HACK and LOOKUP_INTERPOLATION.
16 According to the code comments they weren't very good anyway.
17 ("degrades sound quality noticeably"). I also removed the
18 disclaimer about the "8-bit uLaw to 16-bit PCM and the 13-bit-PCM
19 to 8-bit uLaw tables" disclaimer, since I believe those were the
20 tables I removed.
21 + Removed LOOKUP_SINE since it was already commented out. I think we
22 can count on our target audience having math co-processors
23 nowadays.
24 + Removed USE_LDEXP since it wasn't being used and "it doesn't make
25 much of a difference either way".
26 + Removed decompress hack from open_file() since it didn't look very
27 portable.
28 + Removed heaps of unnecessary constants.
29 + Removed unused functions.
30 + Assume that LINEAR_INTERPOLATION is always used, so remove all
31 code dealing with it not being so. It's not that I think the
32 difference in audio quality is that great, but since it wouldn't
33 compile without code changes I assume no one's used it for quite
34 some time...
35 + Assume PRECALC_LOOPS is always defined. Judging by the comments it
36 may not make much of a difference either way, so why maintain two
37 versions of the same code?
38
39 * Moving several static globals into the MidiSong struct. This
40 includes sample rate, formate, etc. which are now all per-song.
41
42 * Moved some typedefs (e.g. MidiSong) to timidity.h for easy inclusion
43 into the MIDI decoder.
44
45 * Added free_pathlist().
46
47 * Replaced TiMidity's own 8, 16 and 32-bit types with SDL's.
48
49 * Made TiMidity look for its configuration file in both /etc and
50 /usr/local/lib/timidity. (Windows version remains unchanged.)
51
52 * Timidity_PlaySome() now takes three arguments. A MidiSong, a decode
53 buffer and decode buffer size in bytes. (MidiSong is a new argument,
54 and buffer size used to be in samples.)
55
56 In addition, it will return the number of bytes decoded.
57
58 * Added Timidity_Exit().
59
60 * Removed Timidity_Stop() and Timidity_Active(). Stopping playback
61 should be handled by SDL_sound, and Timidity_PlaySome() will return
62 0 when the MIDI stream is finished.
63
64 * Modified the ToneBank stuff to allow some data to be shared between
65 MidiSongs.
66
67 * The following files have been removed: controls.c, controls.h,
68 filter.c, filter.h, sdl_a.c, sdl_c.c
69
70 * config.h has been renamed as options.h to avoid confusion with the
71 automatically generated config.h for SDL_sound.
72
73 * Added support for loading DLS format instruments:
74 Timidity_LoadDLS(), Timidity_FreeDLS(), Timidity_LoadDLSSong()
75
76 * Added Timidity_Init_NoConfig()

2 Preamble
3
4 The intent of this document is to state the conditions under which a
5 Package may be copied, such that the Copyright Holder maintains some
6 semblance of artistic control over the development of the package,
7 while giving the users of the package the right to use and distribute
8 the Package in a more-or-less customary fashion, plus the right to make
9 reasonable modifications.
10
11 Definitions:
12
13 "Package" refers to the collection of files distributed by the
14 Copyright Holder, and derivatives of that collection of files
15 created through textual modification.
16
17 "Standard Version" refers to such a Package if it has not been
18 modified, or has been modified in accordance with the wishes
19 of the Copyright Holder as specified below.
20
21 "Copyright Holder" is whoever is named in the copyright or
22 copyrights for the package.
23
24 "You" is you, if you're thinking about copying or distributing
25 this Package.
26
27 "Reasonable copying fee" is whatever you can justify on the
28 basis of media cost, duplication charges, time of people involved,
29 and so on. (You will not be required to justify it to the
30 Copyright Holder, but only to the computing community at large
31 as a market that must bear the fee.)
32
33 "Freely Available" means that no fee is charged for the item
34 itself, though there may be fees involved in handling the item.
35 It also means that recipients of the item may redistribute it
36 under the same conditions they received it.
37
38 1. You may make and give away verbatim copies of the source form of the
39 Standard Version of this Package without restriction, provided that you
40 duplicate all of the original copyright notices and associated disclaimers.
41
42 2. You may apply bug fixes, portability fixes and other modifications
43 derived from the Public Domain or from the Copyright Holder. A Package
44 modified in such a way shall still be considered the Standard Version.
45
46 3. You may otherwise modify your copy of this Package in any way, provided
47 that you insert a prominent notice in each changed file stating how and
48 when you changed that file, and provided that you do at least ONE of the
49 following:
50
51 a) place your modifications in the Public Domain or otherwise make them
52 Freely Available, such as by posting said modifications to Usenet or
53 an equivalent medium, or placing the modifications on a major archive
54 site such as uunet.uu.net, or by allowing the Copyright Holder to include
55 your modifications in the Standard Version of the Package.
56
57 b) use the modified Package only within your corporation or organization.
58
59 c) rename any non-standard executables so the names do not conflict

61 a separate manual page for each non-standard executable that clearly
62 documents how it differs from the Standard Version.
63
64 d) make other distribution arrangements with the Copyright Holder.
65
66 4. You may distribute the programs of this Package in object code or
67 executable form, provided that you do at least ONE of the following:
68
69 a) distribute a Standard Version of the executables and library files,
70 together with instructions (in the manual page or equivalent) on where
71 to get the Standard Version.
72
73 b) accompany the distribution with the machine-readable source of
74 the Package with your modifications.
75
76 c) give non-standard executables non-standard names, and clearly
77 document the differences in manual pages (or equivalent), together
78 with instructions on where to get the Standard Version.
79
80 d) make other distribution arrangements with the Copyright Holder.
81
82 5. You may charge a reasonable copying fee for any distribution of this
83 Package. You may charge any fee you choose for support of this
84 Package. You may not charge a fee for this Package itself. However,
85 you may distribute this Package in aggregate with other (possibly
86 commercial) programs as part of a larger (possibly commercial) software
87 distribution provided that you do not advertise this Package as a
88 product of your own. You may embed this Package's interpreter within
89 an executable of yours (by linking); this shall be construed as a mere
90 form of aggregation, provided that the complete Standard Version of the
91 interpreter is so embedded.
92
93 6. The scripts and library files supplied as input to or produced as
94 output from the programs of this Package do not automatically fall
95 under the copyright of this Package, but belong to whoever generated
96 them, and may be sold commercially, and may be aggregated with this
97 Package. If such scripts or library files are aggregated with this
98 Package via the so-called "undump" or "unexec" methods of producing a
99 binary executable image, then distribution of such an image shall
100 neither be construed as a distribution of this Package nor shall it
101 fall under the restrictions of Paragraphs 3 and 4, provided that you do
102 not represent such an executable image as a Standard Version of this
103 Package.
104
105 7. C subroutines (or comparably compiled subroutines in other
106 languages) supplied by you and linked into this Package in order to
107 emulate subroutines and variables of the language defined by this
108 Package shall not be considered part of this Package, but are the
109 equivalent of input as in Paragraph 6, provided these subroutines do
110 not change the language in any way that would cause it to fail the
111 regression tests for the language.
112
113 8. Aggregation of this Package with a commercial distribution is always
114 permitted provided that the use of this Package is embedded; that is,
115 when no overt attempt is made to make this Package's interfaces visible
116 to the end user of the commercial distribution. Such use shall not be
117 construed as a distribution of this Package.

2 TiMidity -- Experimental MIDI to WAVE converter

7 Frequently Asked Questions with answers:
8
9 --------------------------------------------------------------------------
10 Q: What is it?
11
12 A: Where? Well Chris, TiMidity is a software-only synthesizer, MIDI
13 renderer, MIDI to WAVE converter, realtime MIDI player for UNIX machines,
14 even (I've heard) a Netscape helper application. It takes a MIDI file
15 and writes a WAVE or raw PCM data or plays it on your digital audio
16 device. It sounds much more realistic than FM synthesis, but you need a
17 ~100Mhz processor to listen to 32kHz stereo music in the background while
18 you work. 11kHz mono can be played on a low-end 486, and, to some, it
19 still sounds better than FM.
20
21 --------------------------------------------------------------------------
22 Q: I don't have a GUS, can I use TiMidity?
23
24 A: Yes. That's the point. You don't need a Gravis Ultrasound to use
25 TiMidity, you just need GUS-compatible patches, which are freely
26 available on the Internet. See below for pointers.
27
28 --------------------------------------------------------------------------
29 Q: I have a GUS, can I use TiMidity?
30
31 A: The DOS port doesn't have GUS support, and TiMidity won't be taking
32 advantage of the board's internal synthesizer under other operating
33 systems either. So it kind of defeats the purpose. But you can use it.
34
35 --------------------------------------------------------------------------
36 Q: I tried playing a MIDI file I got off the Net but all I got was a
37 dozen warnings saying "No instrument mapped to tone bank 0, program
38 xx - this instrument will not be heard". What's wrong?
39
40 A: The General MIDI standard specifies 128 melodic instruments and
41 some sixty percussion sounds. If you wish to play arbitrary General
42 MIDI files, you'll need to get more patch files.
43
44 There's a program called Midia for SGI's, which also plays MIDI
45 files and has a lot more bells and whistles than TiMidity. It uses
46 GUS-compatible patches, too -- so you can get the 8 MB set at
47 ftp://archive.cs.umbc.edu/pub/midia for pretty good GM compatibility.
48
49 There are also many excellent patches on the Ultrasound FTP sites.
50 I can recommend Dustin McCartney's collections gsdrum*.zip and
51 wow*.zip in the "[.../]sound/patches/files" directory. The huge
52 ProPats series (pp3-*.zip) contains good patches as well. General
53 MIDI files can also be found on these sites.
54
55 This site list is from the GUS FAQ:

72
73 --------------------------------------------------------------------------
74 Q: Some files have awful clicks and pops.
75
76 A: Find out which patch is responsible for the clicking (try "timidity
77 -P<patch> <midi/test-decay|midi/test-panning>". Add "strip=tail" in
78 the config file after its name. If this doesn't fix it, mail me the
79 patch.
80
81 --------------------------------------------------------------------------
82 Q: I'm playing Fantasie Impromptu in the background. When I run Netscape,
83 the sound gets choppy and it takes ten minutes to load. What can I do?
84
85 A: Here are some things to try:
86
87 - Use a lower sampling rate.
88
89 - Use mono output. This can improve performance by 10-30%.
90 (Using 8-bit instead of 16-bit output makes no difference.)
91
92 - Use a smaller number of simultaneous voices.
93
94 - Make sure you compiled with FAST_DECAY enabled in options.h
95
96 - Recompile with an Intel-optimized gcc for a 5-15%
97 performance increase.

13 This is the README file for TiMidity v0.2i
14
15 TiMidity is a MIDI to WAVE converter that uses Gravis
16 Ultrasound(*)-compatible patch files to generate digital audio data
17 from General MIDI files. The audio data can be played through any
18 sound device or stored on disk. On a fast machine, music can be
19 played in real time. TiMidity runs under Linux, FreeBSD, HP-UX, SunOS, and
20 Win32, and porting to other systems with gcc should be easy.
21
22 TiMidity Features:
23
24 * 32 or more dynamically allocated fully independent voices
25 * Compatibility with GUS patch files
26 * Output to 16- or 8-bit PCM or uLaw audio device, file, or
27 stdout at any sampling rate
28 * Optional interactive mode with real-time status display
29 under ncurses and SLang terminal control libraries. Also
30 a user friendly motif interface since version 0.2h
31 * Support for transparent loading of compressed MIDI files and
32 patch files
33
34 * Support for the following MIDI events:
35 - Program change
36 - Key pressure
37 - Channel main volume
38 - Tempo
39 - Panning
40 - Damper pedal (Sustain)
41 - Pitch wheel
42 - Pitch wheel sensitivity
43 - Change drum set
44
45 * TiMidity requires sampled instruments (patches) to play MIDI files. You
46 should get the file "timidity-lib-0.1.tar.gz" and unpack it in the same
47 directory where you unpacked the source code archive. You'll want more
48 patches later -- read the file "FAQ" for pointers.
49
50 * Timidity is no longer supported, but can be found by searching the web.

timidity/TODO less more
0 * I don't like the indentation style at all, but for the most part
1 I've left it alone.
2
3 * Much of the code looks ugly to me.
4
5 * The return value from SDL_RWread() is checked inconsistenly.
6
7 * Group the members of MidiSong into logical units, i.e. structs?
8
9 * The debug messages are probably a bit too noisy. I've removed one
10 particularly annoying one, but...
11
12 Some of them should be turned into error messages instead.
13
14 * Can the instrument handling be made more efficient? At the moment
15 different MidiSongs may separately load the same instrument.
16
17 Note that the MidiSong's audio format affects how the instrument is
18 loaded, so it's not as easy as just letting all MidiSongs share tone
19 and drum banks.
20
21 At the moment they do share the data that is simply read from the
22 config file, but that's just a quick hack to avoid having to read
23 the config file every time a MIDI song is loaded.
24
25 * Check if any of MidiStruct's members can safely be made into static
26 globals again.
27
28 * TiMidity++ adds a number of undocumented (?) extensions to the
29 configuration syntax. These are not implemented here. In particular,
30 the "map" keyword used by the "eawpats".
31
32 * The other decoders generally only read as much of the file as is
33 necessary. Could we do that in this decoder as well? (Currently it
34 seems to convert the entire file into MIDI events first.)
35
36 * Can it be optimized?
