2    
3    * packaging changes:    * 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        - fixed compilation with gcc 4.3
9        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10        - fixed configure so it detects x86_64 (#107)
11        - fixes for building with newer MinGW versions
12        - fix for building with bison 2.4 (#111)
13        - fixed building with libgig installed in a non-standard directory
14    
15      * general changes:
16        - bugfix: on some POSIX systems instrument editor plugins refused to
17          load as we used a non-portable Linux specific struct field
18          (fixes bug #70, patch by Ronald Baljeu)
19        - fixed endless loop which occured when loading an instrument editor
20          plugin DLL on Windows systems failed
21        - fixed memory leaks that occurred when liblinuxsampler was unloaded
22        - optimized the SynchronizedConfig class so it doesn't wait
23          unnecessarily long after an update
24        - added support for notifying instrument editors on note-on / note-off
25          events (e.g. to highlight the pressed keys on the virtual keyboard
26          of gigedit)
27        - added support for triggering notes by instrument editors (see above)
28        - be verbose on DLL load errors (on Linux)
29        - fixed di-harmonic triangle LFO implementation (this LFO implementation
30          is only used by very few systems, most pick the int math
31          implementation, which is usually faster)
32        - fixes for audio drivers with varying buffer sizes
33        - experimental support for running LinuxSampler as a DSSI, LV2 and
34          VST plugin
35        - notification events for stream/voice count statistics are now sent
36          only when there are actual changes
37        - added memory ordering constraints to improve stability on
38          multi-core and multi-cpu systems
39        - maximum voices and disk streams can now be altered at runtime
40        - fixed CPU feature detection on x86_64 (maybe fixes #108)
41        - automatic stacktrace mechanism is now turned off by default and can
42          be switched on by command line option "--stacktrace" (the automatic
43          stacktrace mechanism seems to be broken on most systems at the moment)
44        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
45          a pointer to the launched InstrumentEditor object
46        - added optional 3rd party user data parameter for following
47          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
48          InstrumentEditor::Launch(),
49          InstrumentManager::LaunchInstrumentEditor()
50        - theoretical fix: made SynchronizedConfig follow C++0x memory
51          model more strictly
52    
53      * audio driver:
54        - removed the nonsense audio channel constraint (which was hard coded to
55          max. 100 audio channels) for most audio drivers
56        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
57          opposed to the LSCP specs
58        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
59          reflected the wrong value
60        - fixed a memory management bug in ASIO driver
61        - Makefile fix: JACK_CFLAGS wasn't used
62        - JACK: use jack_client_open instead of the deprecated
63          jack_client_new
64        - added (experimental) CoreAudio driver
65    
66      * MIDI driver:
67        - added JACK MIDI driver
68        - dispatch bank select as ordinary CC as well, the user might seriously
69          want to (mis)use it for some purpose ("fixed" in all current MIDI
70          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
71        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, Mme,
72          CoreMidi or AU
73    
74      * instruments database:
75        - avoid time consuming samples scanning when adding instruments
76          to the instruments database
77        - added support for handling lost files in the instruments database
78        - Implemented option for adding instruments in separate directories
79          in the instruments database
80          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
81    
82      * Gigasampler format engine:
83        - fixed a memory leak that could happen when a channel was deleted
84          while notes were playing
85        - made it possible to load an instrument even if the audio thread
86          isn't running
87        - added partial support for the "Controller Triggered" MIDI rule,
88          enough for piano gigs with pedal noise samples
89        - minor fix: only mark FX sends as being modified if really the
90          respective FX send MIDI controller was used
91        - added support for GM global device volume SysEx message
92          (can be selected at compile time to either apply globally to the
93          whole sampler [default] or only to the sampler channels that are
94          connected to the respective MIDI input port the SysEx message arrived
95          on)
96        - bugfix: notes triggered at position 0 in the audio buffer were
97          sometimes wrongly killed in the same buffer, causing no sound to
98          be played
99        - added support for chromatic / drumkit mode Roland GS Sysex message
100          which is usally used to switch a part between chromatic sounds and
101          drumkit sounds (as opposed to their common default setting of MIDI
102          part 10 being a drumkit part and all other ones chromatic parts), in
103          LS however one can switch between the first 16 MIDI instrument maps
104          defined for the sampler
105        - made it possible to create multiple sample channels even if the
106          audio thread isn't running
107        - fixed crash when removing channel with active voices (#116)
108        - bugfix: on sample reference changes (instrument editor), only
109          un-cache the respective sample if it's really not used by any
110          sampler engine anymore
111        - re-cache samples in case they were changed by an instrument editor,
112          e.g. when a sample was added while playing (#82)
113        - fixed hanging notes which occured when note-off event had the exact
114          same time stamp as the voice's note-on event and occured both in the
115          same audio fragment cycle (fixes bug #112)
116        - added support for the "fine tune" and "pitch bend range"
117          instrument-level gig parameters
118        - fixed minor artifacts in pitch bend handling
119        - added support for GS Reset SysEx message
120        - allow gig files to use unlimited downward pitch shifting
121        - added a limit check for upward pitch shifting
122    
123      * LSCP server:
124        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
125          react on MIDI data arriving on certain sampler channels (so far only
126          Note-On and Note-Off events are sent via this LSCP event)
127        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
128          react on MIDI data arriving on certain MIDI input devices (so far only
129          Note-On and Note-Off events are sent via this LSCP event)
130        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
131          SET DB_INSTRUMENT FILE_PATH
132        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
133          frontends to send MIDI messages to specific sampler channel
134        - added two additional fields to GET FILE INSTRUMENT INFO command -
135          KEY_BINDINGS and KEYSWITCH_BINDINGS
136        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
137          was incorrect
138        - Optimized the retrieval of the MIDI instrument mappings
139        - added new LSCP command "SET VOICES" to globally alter the maximum
140          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
141          be triggered respectively
142        - added new LSCP command "SET STREAMS" to globally alter the maximum
143          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
144          which will be triggered respectively
145        - bugfix: retry if "select" returns EINTR (this fixes a crash when
146          a gigedit file dialog is opened)
147        - close all connections when LSCPServer is deleted
148        - hard close of all sockets on exit
149    
150      * Bug fixes:
151        - fixed a crash which occurs when removing a sampler channel waiting
152          to start instrument loading after another channel
153        - fixed a crash which occurs when removing a sampler channel with
154          instrument loading in progress (bug #113)
155        - fixed termination caused by uncaught exception when adding MIDI
156          instrument with PERSISTENT load mode
157        - fixed possible iterator invalidations when resetting the sampler
158        - fixed memory leaks when issuing the following LSCP commands:
159          GET AUDIO_OUTPUT_DRIVER INFO
160          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
161          GET MIDI_INPUT_DRIVER INFO
162          GET MIDI_INPUT_DRIVER_PARAMETER INFO
163        - fixed possible compilation error when sqlite is not present
164        - fixed orphaned pointers when setting maximum voices limit (bug #118)
165        - fixed crash when changing the audio output device of a sampler
166          channel with loaded instrument and start playing notes
167        - fixed endless loop in Engine::SuspendAll() (bug #120)
168        - fixed a low-level atomic load function that was broken on 64-bit
169          PowerPC, which probably could cause crashes on that platform
170    
171    
172    Version 0.5.1 (6 December 2007)
173    
174      * packaging changes:
175        - added autoconf checks for pthread library
176        - added autoconf check for pthread bug found on certain NPTL-enabled
177          glibc versions (see Gentoo bug report #194076)
178        - added autoconf checks for MS Windows
179    
180      * general changes:
181        - bugfix: the thread used by an editor plugin didn't die when the
182          editor closed
183        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
184          out all the space. operator--() did not apply size_mask after
185          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
186          order to avoid problems with the _NonVolatileReader functions.
187        - bugfix: Stream.h: added a missing divide by BytesPerSample in
188          GetWriteSpace(). Since this function is currently only used in
189          the stream's qsort() compare function, it didn't trigger any
190          bugs.
191        - Resampler.h, Synthesizer.h: cubic interpolation now works in
192          24bit mode too. Faster method to read 24bit words on little
193          endian machines (x86): replaced 3 byte reads + shifts with a 1
194          unaligned 32bit read and shift
195        - experimental support for MS Windows (MIDI input via MME, AUDIO
196          output via ASIO)
197        - made handling of SIGINT signal (Ctrl-C) a bit more robust
198        - support for monitoring the total number of active disk streams
199          (new LSCP commands: GET TOTAL_STREAM_COUNT,
200          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
201    
202      * AUDIO driver:
203        - added Windows ASIO low latency audio driver
204    
205      * MIDI driver:
206        - added MME Windows MIDI driver
207    
208      * LSCP server:
209        - added support for Windows style path / filenames, however with
210          forward slash path separators instead of backslash
211          (i.e. "C:/foo/bar.gig")
212        - allow naughty liblscp to send non-string device parameters within
213          apostrophes as well
214        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
215          "LIST FILE INSTRUMENTS <file>" and
216          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
217          about an arbitrary instrument file on the system where the sampler is
218          running on
219    
220    Version 0.5.0 (15 October 2007)
221    
222      * packaging changes:
223        - config.h is not going to be installed along with liblinuxsampler's
224          API header files anymore
225        - only the API relevant header (and source) files will be exported to
226          the Doxygen API documentation (explicitly listed in Doxyfile.in)
227        - added completely new XCode project files for Mac OSX which is now
228          capable to execute our autoconf environment, thus no need anymore
229          to maintain the compile time configuration file (osx/version.h) for
230          OSX manually (patch by Toshi Nagata)
231        - fixed buggy boolean --enable-foo / --disable-foo configure script
232          parameters
233        - global.h now only covers global definitions that are needed for the
234          C++ API header files, all implementation internal global definitions
235          are now in global_private.h
236        - atomic.h is not exposed to the C++ API anymore
237        - no need to include config.h anymore for using LS's API header files
238        - fixed warnings in API doc generation
239    
240      * general changes:
241        - replaced the old, confusing MIDI program change mechanism by a
242          flexible MIDI instrument mapper which allows to map arbitrary
243          (MIDI bank, MIDI program) pairs with arbitrary
244          (engine type, instrument file, file index) triplets which will be
245          loaded on the respective channel when such MIDI program change
246          messages arrive, beside that, each entry allows to define a life-time
247          strategy for the instrument, so the user can define whether the
248          instrument should i.e. be permanently loaded (to be able to switch
249          quickly among sounds) or i.e. loaded just on demand when the
250          respective program change arrives (to safe RAM space), as well as a
251          global volume factor for each entry, so the user can adjust the volume
252          dynamic of his mapped instrument collection without having to modify
253          the instrument files, also one can manage arbitrary amount of such
254          MIDI instrument maps and assign each sampler channel individually
255          a certain map, so that i.e. separation of normal instruments and
256          drumkits is possible
257        - new notification events for tracking changes to audio/MIDI devices,
258          MIDI instrument maps, MIDI instruments, FX sends, global volume.
259        - sampler was limited to load max. 200 instruments in the background
260          due to a constant size RingBuffer FIFO which is now replaced by a
261          dynamic (unlimited) size std::list FIFO
262        - added FX sends, these allow to route audio signals to arbitrary audio
263          output channels for being processed by external effect processors
264          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
265          controllers
266        - global (sampler wide) volume can now be controlled at runtime
267        - Implemented new, improved notification system
268        - fixed compilation errors regarding OSX
269          (patch by Toshi Nagata)
270        - implemented instruments database
271        - added support for escape sequences to the instruments database
272        - added highly experimental support for on-the-fly instrument editing
273          within the sampler's process (by using instrument editor plugins),
274          you'll notice the new "Registered instrument editors:" message on
275          startup, added a new LSCP command:
276          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
277          to spawn a matching instrument editor for the instrument on the
278          given sampler channel, the plugin path can be overridden at compile
279          time with ./configure --enable-plugin-dir=/some/dir
280        - added experimental code for synchronizing instrument editors hosted
281          in the sampler's process to safely edit instruments while playing
282          without a crash (hopefully) by either suspending single regions
283          wherever possible or if unavoidable whole engine(s)
284        - fixed several issues in fundamental "Thread" class: set scheduling
285          policy and priority on thread level, set a minimum stack size for
286          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
287          threads simply inherited properties of starting thread instead of
288          setting their own policy and priority
289        - minor fix in our automatic stack trace mechanism on crashes, the
290          main process did not wait for the stack trace process to finish
291          its output
292        - fixed some minor memory leaks
293        - reenabled assembly features support, at the moment only for
294          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
295        - minor assembly fix in x86 features detection (don't use the PIC
296          register, to avoid relocations in the text segment at runtime)
297        - POSIX callback functions of Thread.h are hidden
298    
299      * MIDI driver:
300        - dispatch bank select (MSB and LSB) messages
301    
302      * audio driver:
303        - the ALSA audio output driver parameters now reflect the correct
304          parameter value ranges for the respective selected sound card
305          (patch by Till Wimmer, a bit fixed and extended)
306    
307      * Gigasampler format engine:
308        - if a filter is used and EG2 finishes before EG1, let the voice
309          die when EG2 has finished (this fixes a problem with clicks and
310          voice starvation for some gigs)
311        - playback is no longer disabled during instrument loading
312        - all notes playing on a channel that changes its instrument keep
313          playing with the old instrument until they get a note off
314          command
315        - EG fix: a release value of zero could cause noises or crash
316        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
317        - EG fine tuning: when attack is zero the EG starts at a level
318          above max sustain level, which means that there is a decay phase
319          even if sustain is 100%
320        - more EG fixes: the level could sometimes go below zero and cause
321          noises or crashes
322        - minor fix of EGDecay (patch by Toshi Nagata)
323        - fixed compiler error when --enable-override-filter-type was
324          supplied to the configure script (fixes #46)
325        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
326          instead of a fix value
327        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
328          127 (solo mode) only kill voices if the respective mode really
329          changed
330    
331      * LSCP server:
332        - fixed compile time error for old Bison versions
333          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
334        - parser now supports extended ASCII character set
335          (up to ASCII code 255, i.e. includes now umlauts and accents)
336        - filename arguments in LSCP commands now allow to use escape
337          sequences, that is directly literal as one of: \', \", \\, \n, \r,
338          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
339          code value like \xf2) (fixes bug #24)
340        - the following LSCP commands now also support escape sequences for at
341          least one of their text-based parameters (i.e. name, description):
342          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
343          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
344          "SET DB_INSTRUMENT_DIRECTORY NAME",
345          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
346          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
347          "FIND DB_INSTRUMENT_DIRECTORIES"
348        - returns verbose syntax errors (line and column where syntax error
349          occured, the unexpected character and the actually expected, possible
350          character(s), the latter only if less than 5 possibilities)
351        - made sure that LSCP syntax is not affected by gigedit locale
352          settings
353        - bugfix regarding strings parameter lists: all comma separated lists
354          of strings were treated as being one string containing commas
355          (fixes #57)
356    
357      * Bug fixes:
358        - fixed crash occurring on certain LSCP scripts (Bug 39)
359        - another thread safety fix for lscp "load engine" and "set
360          channel audio output device"
361        - fixed a crash which occurs when reassigning the same engine
362          on a sampler channel with connected MIDI device
363        - fixed a crash which occurs when changing the number of ports of a MIDI
364          device connected to a sampler channel to number less then or equal
365          to the index of the port to which the sampler channel is connected.
366        - The previous bindings were not been disconnected when altering
367          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
368          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
369        - The active stream/voice count statistic was incorrect.
370        - notification events were not been sent for some sampler
371          channel changes
372        - added default min and max values to restrict the number of allowed
373          audio output channels and MIDI input ports
374        - the connection to the PCM interface is now closed when destroying
375          an audio output device
376        - files with slash in their path or filename could not be loaded
377    
378      * test cases:
379        - updated and fixed (haven't been touched in a while)
380    
381    Version 0.4.0 (24 November 2006)
382    
383      * packaging changes:
384      - changed deprecated copyright attribute to license; added ldconfig      - changed deprecated copyright attribute to license; added ldconfig
385        to post-(un)install steps; added devel package for liblinuxsampler;        to post-(un)install steps; added devel package for liblinuxsampler;
386        to linuxsampler.spec (RPM)        to linuxsampler.spec (RPM)
