* autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
  causing e.g. the libgig test to fail when
  "./configure --disable-jack-driver" was used
  (patch by Alexis Ballier)

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