1 Ann Hell Ex Machina TODO / Bug List
2 ===================================
7 * 1128: The output driver should change the global variable ss_frequency
8 if the underlying hardware doesn't support it. This can't be fixed just
9 by changing it there, because ss_song_convert_events() already used the
10 incorrect ss_frequency to calculate timings. Also, driver initialization
11 can't be moved to run before ss_song_convert_events() because it needs
12 ss_nchannels to be filled with a song-dependent default there.
13 * 1137: Add a test for the 'attack' command.
18 * 1045: Line numbers in compiler errors are incorrectly reported when
19 inserting a block at the end of the line; when the block is inserted,
20 the linefeed has already been read and yyline incremented. This probably
21 occurs also with other directives.
22 * 1046: When a compilation error occurs inside a named block, the reported
23 line number is the one where the insertion occurs, not the one where the
25 * 1022: Add file name to compiler errors.
26 * 1087: When skipping time, MIDI should still write program changes
27 (and probably other messages) to the output device; that is, only
28 notes and time sleeping should be skipped.
29 * 1079: Move midiin.c functionality to main.c.
30 * 1093: External wave file filters (mpg321, flac, etc.) should be
31 configurable via the configuration file (needs #1074 closed).
32 * 1098: Immediate volumes are not implemented.
33 * 1097: Dotted notes are broken when more than one is used.
34 * 1108: Sometimes wave paging hangs. It seems to be related to generators
35 simultaneously using offsets far from each other, so the loaded page
36 keeps bouncing. Setting the page size to a big number (like the actual
37 default, 441000) seems to avoid it, as huge files are not usually used
38 more than once. If you are bit by this bug, set the page size to -1 with
39 the -b command line option.
44 * 1003: There should exist 'some kind' of effect for note volumes
45 to add a random variation, to add 'humanity'. This cannot
46 be a standard digital effect as it should be different
48 * 1005: Vibrato should be variable (from 'no-vibrato' to 'some-vibrato'
50 * 1010: Loop stretching ('stretch wave without pitch change to last
51 exactly N time units').
52 * 1042: Add multiple MIDI devices; a configuration file will match device
53 numbers to real addresses in /dev. Then each track in the song file could
54 have a command to set which MIDI device will the events be sent to.
55 * 1043: The same as the multiple MIDI devices, there should exist multiple
56 dsp devices. This way, a unique computer with more than one sound card
57 can output multichannel songs at a time.
58 * 1074: Add configuration file support.
59 * 1056: Note printing in midiin.c should also print chords.
60 * 1052: Add quantizations.
61 * 1096: ss_outdev.c should be its own project to be used from other
63 * 1094: Add code to specify note lengths in minutes and seconds.
64 * 1100: Add command-line options to mute a track.
65 * 1111: Add some directive to set the block random seed.
66 * 1112: Add some command line argument to set the block random seed.
67 * 1116: Add a command line option to start playing on a given mark.
68 * 1117: The output driver initialization should return the number of
69 channels currently usable. This way, the output engine can remap all
70 channels to the existing ones.
71 * 1121: Add all distortion waveshapers as commented in 'foldback'.
72 * 1125: Now that notes can be altered, there must be a way to temporarily
73 set a note to 'natural' (becuadro).
74 * 1127: Rethink most of the softsynth engine to use pthreads. Each thread
75 could manage one channel, or each one a track.
76 * 1134: Add a new softsynth directive, 'attack', same as 'sustain' but for
77 the start of a generator.
82 * 1000: Convert current event queue to two event queues. The first
83 stage queue should store notes and the second note on / note off
84 events (Tue, 17 Aug 2004 12:00:00 +0200).
85 * 1004: Vibrato for generators (Fri, 13 Aug 2004 11:05:00 +0200).
86 * 1009: Set tempo from a sample loop ('set tempo so that this wave
87 will match exactly one/N measures') (Fri, 16 Aug 2004 18:08:00 +0200).
88 * 1013: Volume should be a command ('v', for example) and not be
89 inherited from previous notes. There should also be settable as
90 relative inc/decrements (as octaves) (Mon, 30 Aug 2004 14:37:59 +0200).
91 * 1014: doc/language.txt is severely outdated
92 (Mon, 30 Aug 2004 15:13:00 +0200)
93 * 1015: Upgrade build system (new config.sh, makefile.in, etc.).
94 (Thu, 09 Sep 2004 18:56:29 +0200).
95 * 1016: Integrate the new compiler (Sun, 12 Sep 2004 16:13:11 +0200).
96 * 1001: Generator should use queues of active / free generators.
97 (Sun, 17 Oct 2004 12:50:10 +0200).
98 * 1012: Portamento should not have a 'time', only a frequency
99 inc/decrement per time unit (Sun, 17 Oct 2004 13:18:04 +0200).
100 * 1018: The 'default' driver should not be bound to the first usable
101 one, but be a sequential try of all available drivers
102 (Thu, 11 Nov 2004 12:18:12 +0100).
103 * 1019: Add libartsc support (Thu, 11 Nov 2004 12:30:02 +0100).
104 * 1023: The SS_FRAMES lex/yacc token should be SS_MSECS, that is,
105 the compiler should not use frames but milliseconds
106 (Tue, 19 Apr 2005 20:05:46 +0200).
107 * 1024: The 'event1' and 'event2' stuff is ugly. It should be called,
108 respectively, 'note stream' (as it's, more or less, device independent)
109 and 'ss stream', which depends of softsynth, frames and such. In the
110 future, there could exist a 'midi stream' if MIDI output is supported
111 (Closed by #1025; Wed, 20 Apr 2005 17:30:31 +0200).
112 * 1033: SONG_EV_SS_NOTE won't work, because freq can't be calculated
113 on compilation time; instead, it should be a generic message
114 (Sat, 23 Apr 2005 10:52:35 +0200).
115 * 1026: Get rid of event.c and event.h (Sat, 23 Apr 2005 12:28:47 +0200).
116 * 1027: Get rid of effect.c and effect.h (Sat, 23 Apr 2005 12:28:51 +0200).
117 * 1031: Add lex/yacc code for processing absolute notes (A1, C#4, F&3)
118 (Sat, 23 Apr 2005 16:14:21 +0200).
119 * 1036: Unify song event types; ss_song should use the same event types
120 (Sun, 24 Apr 2005 10:29:22 +0200).
121 * 1035: The number of compiled tracks should be available somewhere
122 (Sun, 24 Apr 2005 10:35:19 +0200).
123 * 1037: ss_ins_frame() is flawed; as it directly mixes into frame[],
124 each intrument's ss effects affect the previous ones
125 (Mon, 25 Apr 2005 16:42:28 +0200).
126 * 1025: 'event1' has been moved to song.c (generic song event stream)
127 and 'event2' has been moved to ss_song.c (softsynth song event stream),
128 but due to almost all of ss_song.c being private, there is no way to
129 order the instruments and the effects to do anything until a way of
130 storing them is decided. So, project state is really critical now as
131 nothing works (last working version was 'cvs update -D 20050419').
132 (Mon, 25 Apr 2005 18:16:48 +0200).
133 * 1039: Volumes can't be set as integer numbers (0 and 1 should be valid)
134 (Mon, 25 Apr 2005 18:26:06 +0200).
135 * 1038: Comments can't be written inside extended commands
136 (Mon, 25 Apr 2005 18:31:55 +0200).
137 * 1021: Add line number to compiler errors (Mon, 25 Apr 2005 19:11:01 +0200).
138 * 1028: input.c should be ss_input.c (Wed, 27 Apr 2005 08:08:49 +0200).
139 * 1029: output.c should be ss_output.c (Wed, 27 Apr 2005 16:59:34 +0200).
140 * 1044: Line numbers in compiler errors don't work if the error is inside
141 a block or after inserting one
142 (Closed by #1045; Sun, 08 May 2005 10:22:43 +0200).
143 * 1047: Change generators to use just one volume and not a channel map
144 (Mon, 09 May 2005 16:24:13 +0200).
145 * 1049: Since the closing of #1047, the channel map in ss_ins is
146 completely broken (Tue, 10 May 2005 18:27:28 +0200).
147 * 1050: New ss_ins is flawed; volumes are never used
148 (Tue, 10 May 2005 18:41:30 +0200).
149 * 1041: Get rid of CHANNELS and always use dynamic structures or buffers
150 (Tue, 10 May 2005 19:40:52 +0200).
151 * 1048: ss_wave must be dynamic (Thu, 12 May 2005 19:23:13 +0200).
152 * 1032: Refactorize input, ss_gen and ss_ins to always use pointers to
153 struct ss_wave instead of copies of them (Thu, 12 May 2005 19:31:44 +0200).
154 * 1053: Create a tool that will read from a MIDI keyboard and print
155 the played keys on stdout (Closed by #1054;
156 Mon, 23 May 2005 17:04:54 +0200).
157 * 1054: Modify midiin.c to print currently played notes to stdout
158 (Mon, 23 May 2005 19:10:45 +0200).
159 * 1057: The Arts driver hangs forever (Sat, 28 May 2005 13:42:36 +0200).
160 * 1058: The new ss_outdev model seem to have problems with pipe buffer
161 sizes, at least with the OSS driver. Regardless of the number of bytes,
162 data is only read in 256 byte chunks (Sun, 29 May 2005 10:35:27 +0200).
163 * 1030: Refactorize the output system to always use a forked process
164 (Closed by #1062; Sun, 29 May 2005 10:44:39 +0200).
165 * 1061: Process the SONG_EV_SS_NOTE_ON_BY_TIME message, probably by
166 unifying it with the SONG_EV_NOTE_ON (Mon, 30 May 2005 17:22:21 +0200).
167 * 1011: Loop matching ('change wave pitch to last exactly N time units')
168 (Renamed as 'pitch_stretch'; Mon, 30 May 2005 17:23:17 +0200).
169 * 1062: The forked process for sound writing works, but it has proven
170 worse in slow systems. A redesign must be done to also allow direct
171 writing to ports (Closed by #1063; Mon, 30 May 2005 18:14:44 +0200).
172 * 1059: Add channel maps to language (Mon, 30 May 2005 18:50:38 +0200).
173 * 1040: Get rid of all _ prefixed symbols (Mon, 30 May 2005 19:12:19 +0200).
174 * 1064: Document or fix the 'feature' of pitch_stretch that, if the chosen
175 wave can't handle the final frequency (due to min/max boundaries), it can
176 end up not sounding at all (Tue, 31 May 2005 07:41:50 +0200).
177 * 1063: Now that I've tested it with good hardware, the new ss_outdev
178 driver is useless as is due to horrible latency. So, it must be rewritten
179 to do direct writing to devices (Wed, 01 Jun 2005 16:20:01 +0200).
180 * 1051: Unify all header files into annhell.h
181 (Thu, 02 Jun 2005 08:32:31 +0200).
182 * 1065: Create a document about the extended commands
183 (Closed by #1067; Thu, 02 Jun 2005 08:34:28 +0200).
184 * 1008: Support for 'keyboard splits': ranges of notes that a track will
185 ignore. This should allow to have multiple tracks playing the same
186 notes but with different channel maps and, for example, having a
187 guitar glissando pan from left to right
188 (No longer needed, a pan glissando can be done by using plain channel
189 volumes, as they are now immediately applied;
190 Thu, 02 Jun 2005 08:44:45 +0200).
191 * 1068: Add vibrato to ss instruments (Thu, 02 Jun 2005 13:28:39 +0200).
192 * 1069: Add vibrato to language (Thu, 02 Jun 2005 17:28:41 +0200).
193 * 1072: The instrument in midiin should also be an AHXM script
194 (Fri, 03 Jun 2005 19:08:15 +0200).
195 * 1073: The measure boundary checks should include line numbers
196 (Mon, 06 Jun 2005 16:29:28 +0200).
197 * 1066: All code that open files should use a special version of fopen()
198 that searches in a path of directories (Mon, 06 Jun 2005 17:52:44 +0200).
199 * 1017: mp_doccer documentation is severely outdated
200 (Tue, 07 Jun 2005 13:46:36 +0200).
201 * 1077: Delete all stdout crap (Sat, 11 Jun 2005 20:27:43 +0200).
202 * 1078: After a measure change, all measure bar checks break
203 (Sat, 11 Jun 2005 21:03:24 +0200).
204 * 1075: Unify everything inside the same executable (closed by #1079;
205 Sun, 12 Jun 2005 18:34:35 +0200).
206 * 1076: Make the unified executable to accept all options as command
207 line arguments (Sun, 12 Jun 2005 18:34:40 +0200).
208 * 1080: Take last group part into account when calculating its length
209 (Wed, 15 Jun 2005 16:31:30 +0200).
210 * 1081: The end of song is incorrectly detected. It can be reproduced by
211 having a very long note that ends longer after the last inserted event
212 (Thu, 16 Jun 2005 13:42:10 +0200).
213 * 1082: Wave loading should be cached, to optimize the loading of the
214 same sound from different tracks (Closed by #1084;
215 Thu, 16 Jun 2005 14:04:06 +0200).
216 * 1083: When a named block is referenced at the end of a line inside
217 another block, a syntax error is generated (Thu, 16 Jun 2005 18:32:54 +0200).
218 * 1071: Add the posibility to start a song from a given measure or time
219 (Sun, 19 Jun 2005 10:56:11 +0200).
220 * 1085: Add skip_secs capability to MIDI output
221 (Sun, 19 Jun 2005 12:48:51 +0200).
222 * 1002: Build an audio filtering tool to test effects
223 (Discarded; Tue, 21 Jun 2005 16:12:42 +0200).
224 * 1034: tempo_from_wave() will never work; when the wave is loaded, it's
225 too late for the tempo to be set, as the ss_song stream has no tempo
226 information. The only solution is to just print the optimal tempo, for
227 the ahxm programmer to change it manually (Closed by 1060;
228 Tue, 21 Jun 2005 16:13:09 +0200).
229 * 1067: Fill the extended commands document (Tue, 21 Jun 2005 17:19:28 +0200).
230 * 1060: Add print_wave_tempo to language (Thu, 23 Jun 2005 08:22:06 +0200).
231 * 1055: Add signal control to cleanly close the devices
232 (Thu, 23 Jun 2005 13:33:31 +0200).
233 * 1088: The 'wav' command doesn't bang when a sound can't be loaded
234 (Thu, 23 Jun 2005 17:32:49 +0200).
235 * 1090: Add a new sound generator, called 'stream' or something like that,
236 to simply stream a wave file into the current process, meant to avoid
237 loading very large files into memory and to help in using Ann Hell Ex Machina
238 as a remixing tool. These files will probably be limited to using the same
239 sampling rate as ahxm to avoid expensive conversions (Closed by #1091;
240 Mon, 12 Sep 2005 06:26:02 +0200).
241 * 1089: Add support for loading .mp3 files by using a cache (probably
242 in ~/.annhellcache) and external tools as mpg321
243 (Tue, 13 Sep 2005 19:45:29 +0200).
244 * 1086: MIDI output is still done to stdout (file descriptor 2)
245 (Wed, 14 Sep 2005 08:22:07 +0200).
246 * 1095: Clearly document the still unsupported things (for example,
247 double dots in lengths, immediate volumes) (Closed by #1097,
248 #1098; Thu, 13 Oct 2005 17:36:56 +0200).
249 * 1099: Add command-line options to mute and/or solo tracks
250 (closed by #1100 and #1101; Wed, 23 Nov 2005 13:27:15 +0100).
251 * 1101: Add command-line options to 'solo' a track
252 (Wed, 23 Nov 2005 15:54:28 +0100).
253 * 1102: Add a new command to move the current note cursor backwards
254 using note length notation (Tue, 06 Dec 2005 09:15:38 +0100).
255 * 1092: Release 1.0.0 right now and make it a stable CVS branch
256 (Mon, 19 Dec 2005 17:33:58 +0100).
257 * 1104: Tempo changes are very broken (try examples/tempo_change.ahs)
258 (Sat, 07 Jan 2006 17:11:04 +0100).
259 * 1106: Implement func_fader() by using the cursor instead of the
260 size, and deactivating itself by setting e->func to NULL
261 (Closed by #1107; Tue, 17 Jan 2006 08:55:37 +0100).
262 * 1107: Implement func_fader() by not changing the size
263 (Tue, 17 Jan 2006 09:08:39 +0100).
264 * 1105: Modify effects to use struct ss_wave instead of a plain wave
265 (Tue, 17 Jan 2006 15:47:27 +0100).
266 * 1020: When a source file includes multiple songs, there should exist a
267 way to mark song / track changes. This should be used to include text
268 messages as ID3 tags or even to generate .cue / .toc files
269 (Tue, 31 Jan 2006 17:28:33 +0100).
270 * 1109: Wave page loading crashes when trying to load a non-cached wave
271 file (Wed, 01 Feb 2006 15:55:58 +0100).
272 * 1103: Add a command line switch to skip music in the 'hard' way,
273 that is, just skipping the events (Thu, 02 Feb 2006 07:50:29 +0100).
274 * 1091: All 'plain' wave files (i.e., all except .pat files) should be
275 paged instead of read directly in memory (Thu, 02 Feb 2006 07:50:29 +0100).
276 * 1110: Add some way to map mono wave files to certain channels. It can be
277 done by adding two new variables to struct ss_wave: a 'first channel', to
278 hold the first channel that will contain the generated samples (default 0,
279 start from the first channel) and 'skip channels', the number of channels
280 to jump over (default 0, don't skip any sample)
281 (Sat, 04 Feb 2006 08:37:01 +0100).
282 * 1006: A 'choose' option, to take randomly one block or another
283 (blocks seem appropriate, but further study is necessary). A random
284 seed script command is also necessary (Tue, 07 Feb 2006 08:41:35 +0100).
285 * 1084: Add a 'copy' directive that uses ss_ins_copy_layers() to copy
286 the loaded instruments from one track into another
287 (Layer copying no longer supported since using paged waves;
288 Tue, 07 Feb 2006 08:43:59 +0100).
289 * 1114: Add a way to specify, or calculate automatically, the number of
290 channels a softsynth song uses. As of now, the default 2 channel output
291 makes necessary to change it from the command line (as the current
292 behaviour is to simply drop channels bigger than n_channels). Another
293 solution should be to add a directive to 'remap' out-of-bound channels
294 to existing ones (Sat, 19 Aug 2006 19:49:39 +0200).
295 * 1118: If no volume is set in a song, no channel is generated
296 (Sun, 20 Aug 2006 14:30:32 +0200).
297 * 1119: Change the track subcommand in the arpeggiator to be a track
298 offset instead of being an absolute one (Mon, 28 Aug 2006 15:14:03 +0200).
299 * 1070: Portamento support is still uncertain
300 (Sat, 09 Sep 2006 18:29:55 +0200).
301 * 1120: Change the portamento command to be specified in some unit not
302 depending on current sampling rate (Tue, 19 Sep 2006 06:45:06 +0200).
303 * 1007: Support for 'tonalities'; fixed transpositions for each note of
304 the octave so that, for example, a 'f' is always a 'f#' (Closed
305 by #1122; Tue, 19 Sep 2006 06:48:34 +0200).
306 * 1122: Add tonalities as a string of 12 note alterations. Proper
307 tonalities will be predefined as named blocks (like, say, $C_MAJOR)
308 (Closed by #1122; Tue, 19 Sep 2006 14:21:18 +0200).
309 * 1123: Add alterations as a string of 7 note alterations
310 (Tue, 19 Sep 2006 14:21:39 +0200).
311 * 1124: Document alterations (Wed, 20 Sep 2006 06:16:17 +0200).
312 * 1126: Create, as named blocks, presets for standard tonalities

314 * 1129: Wobble effects should have a 'gain' parameter to set the rate of
315 affected / original signal (with a default to 1, all affected /
316 no original) (Sun, 15 Oct 2006 21:00:57 +0200).
317 * 1131: Alterations seem to fail when a note has , or ' on it
318 (Wed, 01 Nov 2006 21:31:51 +0100).
319 * 1133: Change the EOT event to not being inserted in the compilation
320 stage, but when converting to softsynth events; this way tracks with
321 events that are only generated by the arpeggiator would not be silent
322 (as in the "Waiting for Tomorrow" song panned basses)
323 (EOTs are inserted in song_sort(); Thu, 23 Nov 2006 19:05:36 +0100).
324 * 1132: Now that ss_ins_frame() returns 0 if the instrument is disabled
325 and no longer sounding and instruments are disabled on track end, it
326 can be possible to end the song only when no more sound is generated
327 (Thu, 18 Jan 2007 18:22:49 +0100).
328 * 1113: Add a special, non-automatic mark (named START or so) to be set
329 to the time offset where new tracks will start. This way, a song can be
330 made to start at a given offset, easing the creation of 'compilation' or
331 'full album' files. Of course, this mark should be redefinible
332 (Fri, 02 Feb 2007 11:53:58 +0100).
333 * 1115: Add a special, automatic mark (named END or so) that will be
334 set on each track end if it's longer than the previous ones
335 (Mon, 05 Feb 2007 13:42:13 +0100).
336 * 1130: Add an end-of-track event, where effects can be reset (to stop
337 consuming CPU) and instruments released (to free memory)
338 (Closed by #1135; Tue, 13 Feb 2007 11:13:04 +0100).
339 * 1136: Document START and END marks (Wed, 14 Feb 2007 09:00:47 +0100).
340 * 1135: Clear all effects on EOT (Wed, 14 Feb 2007 09:04:32 +0100).
