* added autoconf checks for pthread library
* added autoconf check for pthread bug found on certain NPTL-enabled
  glibc versions (see Gentoo bug report #194076)

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