1 Ann Hell Ex Machina TODO / Bug List
2 ===================================
4 Release Critical Bugs
5 ---------------------
7 * 1017: mp_doccer documentation is severely outdated.
8 * 1022: Add file name to compiler errors.
9 * 1030: Refactorize the output system to always use a forked process.
10 * 1040: Get rid of all _ prefixed symbols.
11 * 1045: Line numbers in compiler errors are incorrectly reported when
12 inserting a block at the end of the line; when the block is inserted,
13 the linefeed has already been read and yyline incremented. This probably
14 occurs also with other directives.
15 * 1051: Unify all header files into annhell.h.
16 * 1052: Add quantizations.
17 * 1055: Add signal control to cleanly close the devices.
18 * 1056: Note printing in midiin.c should correctly print chords.
19 * 1058: The new ss_outdev model seem to have problems with pipe buffer
20 sizes, at least with the OSS driver. Regardless of the number of bytes,
21 data is only read in 256 byte chunks.
23 Open Bugs
24 ---------
26 * 1034: tempo_from_wave() will never work; when the wave is loaded, it's
27 too late for the tempo to be set, as the ss_song stream has no tempo
28 information. The only solution is to just print the optimal tempo, for
29 the ahxm programmer to change it manually.
30 * 1046: When a compilation error occurs inside a named block, the reported
31 line number is the one where the insertion occurs, not the one where the
32 block is defined.
34 Pending Enhancements
35 --------------------
37 * 1002: Build an audio filtering tool to test effects.
38 * 1003: There should exist 'some kind' of effect for note volumes
39 to add a random variation, to add 'humanity'. This cannot
40 be a standard digital effect as it should be different
41 for each note.
42 * 1005: Vibrato should be variable (from 'no-vibrato' to 'some-vibrato'
43 in the same note).
44 * 1006: A 'choose' option, to take randomly one block or another
45 (blocks seem appropriate, but further study is necessary). A random
46 seed script command is also necessary.
47 * 1007: Support for 'tonalities'; fixed transpositions for each note of
48 the octave so that, for example, a 'f' is always a 'f#'.
49 * 1008: Support for 'keyboard splits': ranges of notes that a track will
50 ignore. This should allow to have multiple tracks playing the same
51 notes but with different channel maps and, for example, having a
52 guitar glissando pan from left to right.
53 * 1010: Loop stretching ('stretch wave without pitch change to last
54 exactly N time units').
55 * 1011: Loop matching ('change wave pitch to last exactly N time units').
56 * 1020: When a source file includes multiple songs, there should exist a
57 way to mark song / track changes. This should be used to include text
58 messages as ID3 tags or even to generate .cue / .toc files.
59 * 1042: Add multiple MIDI devices; a configuration file will match device
60 numbers to real addresses in /dev. Then each track in the song file could
61 have a command to set which MIDI device will the events be sent to.
62 * 1043: The same as the multiple MIDI devices, there should exist multiple
63 dsp devices. This way, a unique computer with more than one sound card
64 can output multichannel songs at a time.
66 Closed
67 ------
69 * 1000: Convert current event queue to two event queues. The first
70 stage queue should store notes and the second note on / note off
71 events (Tue, 17 Aug 2004 12:00:00 +0200).
72 * 1004: Vibrato for generators (Fri, 13 Aug 2004 11:05:00 +0200).
73 * 1009: Set tempo from a sample loop ('set tempo so that this wave
74 will match exactly one/N measures') (Fri, 16 Aug 2004 18:08:00 +0200).
75 * 1013: Volume should be a command ('v', for example) and not be
76 inherited from previous notes. There should also be settable as
77 relative inc/decrements (as octaves) (Mon, 30 Aug 2004 14:37:59 +0200).
78 * 1014: doc/language.txt is severely outdated
79 (Mon, 30 Aug 2004 15:13:00 +0200)
80 * 1015: Upgrade build system (new config.sh, makefile.in, etc.).
81 (Thu, 09 Sep 2004 18:56:29 +0200).
82 * 1016: Integrate the new compiler (Sun, 12 Sep 2004 16:13:11 +0200).
83 * 1001: Generator should use queues of active / free generators.
84 (Sun, 17 Oct 2004 12:50:10 +0200).
85 * 1012: Portamento should not have a 'time', only a frequency
86 inc/decrement per time unit (Sun, 17 Oct 2004 13:18:04 +0200).
87 * 1018: The 'default' driver should not be bound to the first usable
88 one, but be a sequential try of all available drivers
89 (Thu, 11 Nov 2004 12:18:12 +0100).
90 * 1019: Add libartsc support (Thu, 11 Nov 2004 12:30:02 +0100).
91 * 1023: The SS_FRAMES lex/yacc token should be SS_MSECS, that is,
92 the compiler should not use frames but milliseconds
93 (Tue, 19 Apr 2005 20:05:46 +0200).
94 * 1024: The 'event1' and 'event2' stuff is ugly. It should be called,
95 respectively, 'note stream' (as it's, more or less, device independent)
96 and 'ss stream', which depends of softsynth, frames and such. In the
97 future, there could exist a 'midi stream' if MIDI output is supported
98 (Closed by #1025; Wed, 20 Apr 2005 17:30:31 +0200).
99 * 1033: SONG_EV_SS_NOTE won't work, because freq can't be calculated
100 on compilation time; instead, it should be a generic message
101 (Sat, 23 Apr 2005 10:52:35 +0200).
102 * 1026: Get rid of event.c and event.h (Sat, 23 Apr 2005 12:28:47 +0200).
103 * 1027: Get rid of effect.c and effect.h (Sat, 23 Apr 2005 12:28:51 +0200).
104 * 1031: Add lex/yacc code for processing absolute notes (A1, C#4, F&3)
105 (Sat, 23 Apr 2005 16:14:21 +0200).
106 * 1036: Unify song event types; ss_song should use the same event types
107 (Sun, 24 Apr 2005 10:29:22 +0200).
108 * 1035: The number of compiled tracks should be available somewhere
109 (Sun, 24 Apr 2005 10:35:19 +0200).
110 * 1037: ss_ins_frame() is flawed; as it directly mixes into frame[],
111 each intrument's ss effects affect the previous ones
112 (Mon, 25 Apr 2005 16:42:28 +0200).
113 * 1025: 'event1' has been moved to song.c (generic song event stream)
114 and 'event2' has been moved to ss_song.c (softsynth song event stream),
115 but due to almost all of ss_song.c being private, there is no way to
116 order the instruments and the effects to do anything until a way of
117 storing them is decided. So, project state is really critical now as
118 nothing works (last working version was 'cvs update -D 20050419').
119 (Mon, 25 Apr 2005 18:16:48 +0200).
120 * 1039: Volumes can't be set as integer numbers (0 and 1 should be valid)
121 (Mon, 25 Apr 2005 18:26:06 +0200).
122 * 1038: Comments can't be written inside extended commands
123 (Mon, 25 Apr 2005 18:31:55 +0200).
124 * 1021: Add line number to compiler errors (Mon, 25 Apr 2005 19:11:01 +0200).
125 * 1028: input.c should be ss_input.c (Wed, 27 Apr 2005 08:08:49 +0200).
126 * 1029: output.c should be ss_output.c (Wed, 27 Apr 2005 16:59:34 +0200).
127 * 1044: Line numbers in compiler errors don't work if the error is inside
128 a block or after inserting one
129 (Closed by #1045; Sun, 08 May 2005 10:22:43 +0200).
130 * 1047: Change generators to use just one volume and not a channel map
131 (Mon, 09 May 2005 16:24:13 +0200).
132 * 1049: Since the closing of #1047, the channel map in ss_ins is
133 completely broken (Tue, 10 May 2005 18:27:28 +0200).
134 * 1050: New ss_ins is flawed; volumes are never used
135 (Tue, 10 May 2005 18:41:30 +0200).
136 * 1041: Get rid of CHANNELS and always use dynamic structures or buffers
137 (Tue, 10 May 2005 19:40:52 +0200).
138 * 1048: ss_wave must be dynamic (Thu, 12 May 2005 19:23:13 +0200).
139 * 1032: Refactorize input, ss_gen and ss_ins to always use pointers to
140 struct ss_wave instead of copies of them (Thu, 12 May 2005 19:31:44 +0200).
141 * 1053: Create a tool that will read from a MIDI keyboard and print
142 the played keys on stdout (Closed by #1054;
143 Mon, 23 May 2005 17:04:54 +0200).
144 * 1054: Modify midiin.c to print currently played notes to stdout
145 (Mon, 23 May 2005 19:10:45 +0200).
146 * 1057: The Arts driver hangs forever (Sat, 28 May 2005 13:42:36 +0200).
