File size: 19205 byte(s)
* minor code refactoring of win32 Condition code
* preparations for release 0.5.1

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