* fixed compilation with gcc 4.3

1 schoenebeck 1599 Version CVS HEAD (?)
2    
3 schoenebeck 1639 * packaging changes:
4     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5     causing e.g. the libgig test to fail when
6     "./configure --disable-jack-driver" was used
7     (patch by Alexis Ballier)
8 persson 1713 - fixed compilation with gcc 4.3
9 schoenebeck 1639
10 schoenebeck 1601 * general changes:
11     - bugfix: on some POSIX systems instrument editor plugins refused to
12     load as we used a non-portable Linux specific struct field
13     (fixes bug #70, patch by Ronald Baljeu)
14 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
15     plugin DLL on Windows systems failed
16 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
17     - optimized the SynchronizedConfig class so it doesn't wait
18     unnecessarily long after an update
19 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
20     events (e.g. to highlight the pressed keys on the virtual keyboard
21     of gigedit)
22 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
23 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
24 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
25     is only used by very few systems, most pick the int math
26     implementation, which is usually faster)
27 schoenebeck 1601
28 schoenebeck 1599 * audio driver:
29     - removed the nonsense audio channel constraint (which was hard coded to
30     max. 100 audio channels) for most audio drivers
31 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
32     opposed to the LSCP specs
33 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
34     reflected the wrong value
35 persson 1644 - fixed a memory management bug in ASIO driver
36 schoenebeck 1599
37 persson 1651 * MIDI driver:
38     - added JACK MIDI driver
39    
40 schoenebeck 1604 * instruments database:
41 iliev 1603 - avoid time consuming samples scanning when adding instruments
42     to the instruments database
43    
44 persson 1644 * Gigasampler format engine:
45     - fixed a memory leak that could happen when a channel was deleted
46     while notes were playing
47 persson 1646 - made it possible to load an instrument even if the audio thread
48     isn't running
49 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
50     enough for piano gigs with pedal noise samples
51 persson 1644
52 schoenebeck 1687 * LSCP server:
53     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
54     react on MIDI data arriving on certain sampler channels (so far only
55     Note-On and Note-Off events are sent via this LSCP event)
56 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
57     react on MIDI data arriving on certain MIDI input devices (so far only
58     Note-On and Note-Off events are sent via this LSCP event)
59 schoenebeck 1687
60 schoenebeck 1560 Version 0.5.1 (6 December 2007)
61 schoenebeck 1454
62     * packaging changes:
63     - added autoconf checks for pthread library
64     - added autoconf check for pthread bug found on certain NPTL-enabled
65     glibc versions (see Gentoo bug report #194076)
66 senoner 1502 - added autoconf checks for MS Windows
67 schoenebeck 1454
68 persson 1455 * general changes:
69     - bugfix: the thread used by an editor plugin didn't die when the
70     editor closed
71 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
72     out all the space. operator--() did not apply size_mask after
73     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
74     order to avoid problems with the _NonVolatileReader functions.
75     - bugfix: Stream.h: added a missing divide by BytesPerSample in
76     GetWriteSpace(). Since this function is currently only used in
77     the stream's qsort() compare function, it didn't trigger any
78     bugs.
79     - Resampler.h, Synthesizer.h: cubic interpolation now works in
80     24bit mode too. Faster method to read 24bit words on little
81     endian machines (x86): replaced 3 byte reads + shifts with a 1
82     unaligned 32bit read and shift
83     - experimental support for MS Windows (MIDI input via MME, AUDIO
84     output via ASIO)
85     - made handling of SIGINT signal (Ctrl-C) a bit more robust
86 iliev 1541 - support for monitoring the total number of active disk streams
87     (new LSCP commands: GET TOTAL_STREAM_COUNT,
88     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
89 persson 1455
90 senoner 1500 * AUDIO driver:
91 persson 1534 - added Windows ASIO low latency audio driver
92 senoner 1500
93 senoner 1485 * MIDI driver:
94 schoenebeck 1495 - added MME Windows MIDI driver
95 senoner 1485
96 schoenebeck 1471 * LSCP server:
97     - added support for Windows style path / filenames, however with
98     forward slash path separators instead of backslash
99     (i.e. "C:/foo/bar.gig")
100 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
101     apostrophes as well
102 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
103     "LIST FILE INSTRUMENTS <file>" and
104     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
105     about an arbitrary instrument file on the system where the sampler is
106     running on
107 schoenebeck 1471
108 schoenebeck 1424 Version 0.5.0 (15 October 2007)
109 schoenebeck 947
110 schoenebeck 1065 * packaging changes:
111 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
112     API header files anymore
113 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
114     the Doxygen API documentation (explicitly listed in Doxyfile.in)
115 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
116     capable to execute our autoconf environment, thus no need anymore
117     to maintain the compile time configuration file (osx/version.h) for
118     OSX manually (patch by Toshi Nagata)
119 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
120     parameters
121 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
122     C++ API header files, all implementation internal global definitions
123     are now in global_private.h
124     - atomic.h is not exposed to the C++ API anymore
125     - no need to include config.h anymore for using LS's API header files
126     - fixed warnings in API doc generation
127 schoenebeck 1065
128 schoenebeck 947 * general changes:
129     - replaced the old, confusing MIDI program change mechanism by a
130     flexible MIDI instrument mapper which allows to map arbitrary
131 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
132 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
133     loaded on the respective channel when such MIDI program change
134     messages arrive, beside that, each entry allows to define a life-time
135     strategy for the instrument, so the user can define whether the
136     instrument should i.e. be permanently loaded (to be able to switch
137     quickly among sounds) or i.e. loaded just on demand when the
138     respective program change arrives (to safe RAM space), as well as a
139     global volume factor for each entry, so the user can adjust the volume
140     dynamic of his mapped instrument collection without having to modify
141 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
142     MIDI instrument maps and assign each sampler channel individually
143     a certain map, so that i.e. separation of normal instruments and
144     drumkits is possible
145 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
146     MIDI instrument maps, MIDI instruments, FX sends, global volume.
147 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
148     due to a constant size RingBuffer FIFO which is now replaced by a
149     dynamic (unlimited) size std::list FIFO
150 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
151     output channels for being processed by external effect processors
152     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
153     controllers
154 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
155 iliev 1130 - Implemented new, improved notification system
156 schoenebeck 1149 - fixed compilation errors regarding OSX
157     (patch by Toshi Nagata)
158 iliev 1161 - implemented instruments database
159 iliev 1345 - added support for escape sequences to the instruments database
160 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
161     within the sampler's process (by using instrument editor plugins),
162     you'll notice the new "Registered instrument editors:" message on
163 schoenebeck 1407 startup, added a new LSCP command:
164     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
165 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
166     given sampler channel, the plugin path can be overridden at compile
167     time with ./configure --enable-plugin-dir=/some/dir
168 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
169     in the sampler's process to safely edit instruments while playing
170     without a crash (hopefully) by either suspending single regions
171     wherever possible or if unavoidable whole engine(s)
172 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
173     policy and priority on thread level, set a minimum stack size for
174     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
175     threads simply inherited properties of starting thread instead of
176     setting their own policy and priority
177 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
178     main process did not wait for the stack trace process to finish
179     its output
180 persson 1248 - fixed some minor memory leaks
181 schoenebeck 1259 - reenabled assembly features support, at the moment only for
182     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
183 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
184     register, to avoid relocations in the text segment at runtime)
185 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
186 schoenebeck 947
187     * MIDI driver:
188     - dispatch bank select (MSB and LSB) messages
189    
190 schoenebeck 1049 * audio driver:
191     - the ALSA audio output driver parameters now reflect the correct
192     parameter value ranges for the respective selected sound card
193     (patch by Till Wimmer, a bit fixed and extended)
194    
195 persson 951 * Gigasampler format engine:
196     - if a filter is used and EG2 finishes before EG1, let the voice
197     die when EG2 has finished (this fixes a problem with clicks and
198     voice starvation for some gigs)
199 persson 1038 - playback is no longer disabled during instrument loading
200     - all notes playing on a channel that changes its instrument keep
201     playing with the old instrument until they get a note off
202     command
203 persson 1039 - EG fix: a release value of zero could cause noises or crash
204 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
205 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
206     above max sustain level, which means that there is a decay phase
207     even if sustain is 100%
208 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
209     noises or crashes
210 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
211 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
212     supplied to the configure script (fixes #46)
213 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
214     instead of a fix value
215 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
216     127 (solo mode) only kill voices if the respective mode really
217     changed
218 persson 951
219 schoenebeck 1244 * LSCP server:
220     - fixed compile time error for old Bison versions
221     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
222 schoenebeck 1245 - parser now supports extended ASCII character set
223     (up to ASCII code 255, i.e. includes now umlauts and accents)
224     - filename arguments in LSCP commands now allow to use escape
225     sequences, that is directly literal as one of: \', \", \\, \n, \r,
226     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
227     code value like \xf2) (fixes bug #24)
228 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
229     least one of their text-based parameters (i.e. name, description):
230     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
231     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
232     "SET DB_INSTRUMENT_DIRECTORY NAME",
233     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
234     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
235     "FIND DB_INSTRUMENT_DIRECTORIES"
236 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
237     occured, the unexpected character and the actually expected, possible
238     character(s), the latter only if less than 5 possibilities)
239 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
240     settings
241 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
242     of strings were treated as being one string containing commas
243     (fixes #57)
244 schoenebeck 1244
245 iliev 959 * Bug fixes:
246     - fixed crash occurring on certain LSCP scripts (Bug 39)
247 persson 1038 - another thread safety fix for lscp "load engine" and "set
248     channel audio output device"
249 iliev 1283 - fixed a crash which occurs when reassigning the same engine
250     on a sampler channel with connected MIDI device
251 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
252     device connected to a sampler channel to number less then or equal
253     to the index of the port to which the sampler channel is connected.
254 iliev 1296 - The previous bindings were not been disconnected when altering
255     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
256     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
257 iliev 1297 - The active stream/voice count statistic was incorrect.
258 iliev 1298 - notification events were not been sent for some sampler
259     channel changes
260 iliev 1305 - added default min and max values to restrict the number of allowed
261     audio output channels and MIDI input ports
262 iliev 1306 - the connection to the PCM interface is now closed when destroying
263     an audio output device
264 schoenebeck 1332 - files with slash in their path or filename could not be loaded
265 iliev 959
266 schoenebeck 1221 * test cases:
267     - updated and fixed (haven't been touched in a while)
268    
269 schoenebeck 937 Version 0.4.0 (24 November 2006)
270 persson 696
271 schoenebeck 697 * packaging changes:
272 capela 868 - changed deprecated copyright attribute to license; added ldconfig
273     to post-(un)install steps; added devel package for liblinuxsampler;
274     to linuxsampler.spec (RPM)
275 schoenebeck 697 - install necessary development header files for allowing 3rd party
276     applications to link against liblinuxsampler
277     - liblinuxsampler's API documentation can be generated with 'make docs'
278     (Doxygen required)
279 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
280     implementation (currently either an integer math solution or a
281     di-harmonic approximation), automatic detection can be overriden
282     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
283     configure script argument though (mandatory for cross-compilation)
284 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
285     provided some on his own (as CXXFLAGS)
286 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
287     messages
288 schoenebeck 852 - added compile time options to allow disabling the various audio and
289     MIDI drivers
290 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
291     (patch by Ebrahim Mayat)
292 schoenebeck 697
293 persson 696 * Gigasampler format engine:
294 schoenebeck 738 - extensive synthesis optimization
295     (reimplementation of EGs and LFO(s), removed synthesis parameter
296     prerendering and the synthesis parameter matrix in general, splitting
297     each audio fragment into subfragments now where each subfragment uses
298 persson 830 constant pitch and filter coefficients. The volume coefficient is
299     linearly interpolated inside a subfragment, unless
300     --disable-interpolate-volume is set.)
301 persson 696 - fine tuning of the EG modulation parameters
302 persson 729 - improved filter cutoff calculation by adding support for the
303     following gig parameters: Cutoff freq (used when no cutoff
304     controller is defined), Control invert, Minimum cutoff, Velocity
305 persson 791 curve and Velocity range. The keyboard tracking now scales
306     cutoff frequency instead of resonance.
307 persson 877 - added support for gig parameter Resonance.
308 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
309 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
310     which can be overridden with --enable-global-attenuation
311 persson 783 - EG fixes: made the length of "attack hold" stage more
312     accurate. Release stage can now start before attack stage
313 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
314     time now has a minimal value to prevent clicks.
315 persson 799 - fixed pitch changes larger than one octave
316 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
317     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
318     all modes can be altered via standard GM messages, that is CC5 for
319     altering portamento time, CC65 for enabling / disabling portamento
320     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
321 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
322     parameter) and crossfade
323 persson 831 - added support for the "attenuation controller threshold" gig
324     parameter
325 persson 832 - added smoothing of volume changes caused by control change
326     messages
327 persson 865 - sample loop parameters are now taken from the DimensionRegion
328     instead of the wave chunk
329     - fixed keyswitching for v3 gigs with a number of keyswitch splits
330     not equal to a power of two
331 persson 877 - reimplementation of the filter algorithm. The new filter is more
332     accurate and supports all gig filter types, including bandreject
333     and lowpass turbo.
334 persson 903 - real support for 24 bit samples - samples are not truncated to
335     16 bits anymore
336     - support for aftertouch (channel pressure, not polyphonic
337     aftertouch)
338 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
339     amplifying from 0)
340 persson 696
341 schoenebeck 711 * LSCP server:
342     - fixed application exit on broken pipe error (fixes bug #20)
343 iliev 793 - fixed the notification messages delay due to lack of
344     network activity (fixes bug #26)
345 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
346     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
347 schoenebeck 711
348 schoenebeck 838 * audio driver:
349     - added aRts audio output driver (by no means RT safe)
350    
351 schoenebeck 775 * MIDI driver:
352     - fixed legacy sysex code which caused dispatching of MIDI SysEx
353     messages several times instead of once
354 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
355     for events (i.e. for offline rendering based MIDI drivers)
356 persson 922 - added checks for bad MIDI data
357 schoenebeck 775
358 schoenebeck 900 * linuxsampler application:
359     - show available sampler engine types on startup
360    
361 schoenebeck 705 * general changes:
362     - support for muting sampler channels and solo mode of the same, two new
363     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
364     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
365     introduced for this, the behavior is the same like on a mixer console
366 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
367     --enable-process-muted-channels which can be used to enable the
368     processing of muted channels.
369 iliev 777 - support for sostenuto pedal
370 iliev 779 - support for monitoring the total number of active voices
371 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
372     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
373 persson 835 - fixed some memory management errors
374 persson 841 - fixed some concurrency problems that could lead to crashes when
375     LSCP commands were executed
376 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
377     sampler channel (fixes bug #36)
378 schoenebeck 705
379 schoenebeck 692 Version 0.3.3 (15 July 2005)
380 schoenebeck 686
381     * packaging changes:
382     - fixed compilation with gcc 4.0
383    
384 schoenebeck 687 * Gigasampler format engine:
385     - LFO preprocessing was performed even though the respective LFO was
386     disabled by the instrument patch (minor efficiency fix)
387 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
388     for volume ramp downs in the same fragment (needed for current voice
389     stealing implementation) then simply inform the user with a warning
390     about possible click sounds and reduce the volume ramp down
391     appropriately instead of cancelling the audio device connection
392 schoenebeck 687
393 schoenebeck 677 Version 0.3.2 (24 June 2005)
394 schoenebeck 609
395     * packaging changes:
396     - updated autotools build files to compile on OS X
397     (conditional compilation of CoreMIDI and MidiShare drivers)
398 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
399     './configure --disable-asm' (definitely not recommended)
400 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
401     - require automake (>= 1.5) for 'make -f Makefile.cvs'
402     (due to 'dist-bzip2' automake option)
403 schoenebeck 649
404     * Gigasampler format engine:
405     - support for the gig parameters for "release velocity response" curves
406     - fine tuning of the EGADSR envelope
407     - volume of release triggered samples now depends on note-on velocity,
408     note length and gig parameter "release trigger decay" instead of
409     note-off velocity.
410 schoenebeck 663 - revised voice stealing
411     (fixes crash and endless loop caused by voice stealing)
412 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
413 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
414     instead of when the respective voice is actually launched
415     (fixes undefined behavior if stolen voices belonged to a key group -
416     this case was followed by a "killed voice survived" error message)
417 schoenebeck 669 - fixed minor issue with null/silence samples
418     (those stole voices even though they don't need a voice at all which
419     resulted in "voice stealing didn't work out" messages)
420 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
421     instrument or audio output device change
422 schoenebeck 654
423 schoenebeck 620 * LSCP server:
424 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
425 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
426 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
427 schoenebeck 609
428 schoenebeck 668 * linuxsampler application:
429     - added command line parameters --lscp-addr and --lscp-port to override
430     default IP address and port of LSCP server
431    
432 schoenebeck 579 Version 0.3.1 (24 May 2005)
433    
434     * initial release
