* bugfix: the thread used by an editor plugin didn't die when the
  editor closed

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