3    * packaging changes:    * packaging changes:
4        - fixed building with newer MinGW-w64
5    
6      * general changes:
7        - Refactoring: moved the independent code from
8          the Gigasampler format engine to base classes
9        - command line option '--profile' is currently disabled, since the
10          respective profiling code is currently broken
11        - Introduced support for optional environment variable
12          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
13          where the sampler shall look for instrument editor plugins
14          (patch by Luis Garrido, slightly modified).
15    
16      * Gigasampler format engine:
17        - implemented the "round robin keyboard" dimension
18        - fixed round robin and random dimensions for cases when number of
19          dimension zones is not a power of two
20        - made round robin use a counter for each region instead of each
21          key
22    
23      * SFZ format engine:
24        - Initial implementation (not usable yet)
25        - added support for v2 multiple stage envelope generators
26        - added a fine-tuned v1 envelope generator instead of using the
27          one from the gig engine
28        - fixed memory leak and memory handling errors
29        - added support for trigger=first, trigger=legato and sw_previous
30        - allow non-numerical key values ("C#4" for example)
31        - "key" opcode now sets pitch_keycenter too
32        - fixed error when unloading instrument with same sample used by
33          multiple regions
34        - added some opcode aliases, like loopmode for loop_mode, to be
35          more compatible
36        - added support for trigger=release and rt_decay
37        - added support for off_mode=normal
38        - added support for random, seq_position, seq_length and volume
39        - added v1 LFO opcodes to parser (no support in engine yet)
40        - added support for amp_veltrack and amp_velcurve_N
41        - fine-tuned the default velocity curve
42        - added support for transpose
43        - fixed crash when using sw_down/up
44        - improved logic for sw_lokey/hikey/up/down/last
45        - added more v1 aliases to parser
46        - reduced memory usage for sfz data
47    
48      * SoundFont format engine:
49        - Initial implementation (not usable yet)
50    
51      * Host plugins:
52        - AU bugfix: failed to destroy its audio/MIDI devices
53        - Listen to all interfaces on Mac OS X (INADDR_ANY)
54        - VST bugfix: If the host called resume() before and after
55          changing sample rate or block size, the number of channels was
56          incorrectly set to two. This caused silence in Cubase 5.
57    
58      * MIDI driver:
59        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
60          the ALSA sequencer client name
61    
62      * LSCP server:
63        - added support for sending MIDI CC messages via LSCP command
64          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
65    
66      * Bug fixes:
67        - Fixed crash which may occur when MIDI key + transpose is out of range
68    
69    Version 1.0.0 (31 July 2009)
70    
71      * packaging changes:
72        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
73          causing e.g. the libgig test to fail when
74          "./configure --disable-jack-driver" was used
75          (patch by Alexis Ballier)
76        - fixed compilation with gcc 4.3
77        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
78        - fixed configure so it detects x86_64 (#107)
79        - fixes for building with newer MinGW versions
80        - fix for building with bison 2.4 (#111)
81        - fixed building with libgig installed in a non-standard directory
82        - minor fix in configure for mmsystem.h detection on MinGW
83        - Windows: look for editor plugins and Fantasia using base
84          directory of liblinuxsampler dll (look in the same directory and one
85          directory above)
86        - configure script fix: removed unconditional use of SSE
87        - fixed building with sqlite installed in a non-standard directory
88        - when cross-compiling, don't try to create instruments.db
89        - fix for new mingw-w64 version, which has usleep
90    
91      * general changes:
92        - bugfix: on some POSIX systems instrument editor plugins refused to
93          load as we used a non-portable Linux specific struct field
94          (fixes bug #70, patch by Ronald Baljeu)
95        - fixed endless loop which occured when loading an instrument editor
96          plugin DLL on Windows systems failed
97        - fixed memory leaks that occurred when liblinuxsampler was unloaded
98        - optimized the SynchronizedConfig class so it doesn't wait
99          unnecessarily long after an update
100        - added support for notifying instrument editors on note-on / note-off
101          events (e.g. to highlight the pressed keys on the virtual keyboard
102          of gigedit)
103        - added support for triggering notes by instrument editors (see above)
104        - be verbose on DLL load errors (on Linux)
105        - fixed di-harmonic triangle LFO implementation (this LFO implementation
106          is only used by very few systems, most pick the int math
107          implementation, which is usually faster)
108        - fixes for audio drivers with varying buffer sizes
109        - experimental support for running LinuxSampler as a DSSI, LV2 and
110          VST plugin
111        - notification events for stream/voice count statistics are now sent
112          only when there are actual changes
113        - added memory ordering constraints to improve stability on
114          multi-core and multi-cpu systems
115        - maximum voices and disk streams can now be altered at runtime
116        - fixed CPU feature detection on x86_64 (maybe fixes #108)
117        - automatic stacktrace mechanism is now turned off by default and can
118          be switched on by command line option "--stacktrace" (the automatic
119          stacktrace mechanism seems to be broken on most systems at the moment)
120        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
121          a pointer to the launched InstrumentEditor object
122        - added optional 3rd party user data parameter for following
123          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
124          InstrumentEditor::Launch(),
125          InstrumentManager::LaunchInstrumentEditor()
126        - theoretical fix: made SynchronizedConfig follow C++0x memory
127          model more strictly
128        - fixes for using large audio device buffers
129        - Windows: add the installation directory to the DLL search path
130          when loading an editor plugin (solves problems with VST and
131          gigedit on systems with other GTK versions installed)
132    
133      * audio driver:
134        - removed the nonsense audio channel constraint (which was hard coded to
135          max. 100 audio channels) for most audio drivers
136        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
137          opposed to the LSCP specs
138        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
139          reflected the wrong value
140        - fixed a memory management bug in ASIO driver
141        - Makefile fix: JACK_CFLAGS wasn't used
142        - JACK: use jack_client_open instead of the deprecated
143          jack_client_new
144        - added (experimental) CoreAudio driver
145        - applied old fixes to the ASIO driver that were included in the
146          previous binary release but accidentally never committed to CVS
147          (fixes #117)
148        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
149          win64)
150        - VST: added support for sample rate and buffer size changes
151        - VST: close editor (Fantasia) when the VST is removed
152        - VST: avoid opening Fantasia more than once for each VST instance
153        - VST: export main function as "main" on Linux too (fix for
154          energyXT)
155        - VST: changed number of output channels from one stereo to 16
156          stereo
157        - added channel routing, fxsends and midi maps to the settings
158          stored in the plugin state
159        - performance optimization of AudioChannel::MixTo() and
160          AudioChannel::CopyTo() methods using GCC vector exensions
161          (if available)
162        - ASIO fixes: avoid initializing the device twice, avoid throwing
163          exception when getting parameters from a disconnected device
164    
165      * MIDI driver:
166        - added JACK MIDI driver
167        - dispatch bank select as ordinary CC as well, the user might seriously
168          want to (mis)use it for some purpose ("fixed" in all current MIDI
169          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
170        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
171          CoreMidi or AU
172        - fixed mingw-w64 compilation error in MME driver
173        - made program change handling in MIDI thread real-time safe by
174          moving the logic to a non-RT thread
175        - fixed minor memory leak in ALSA driver
176    
177      * instruments database:
178        - avoid time consuming samples scanning when adding instruments
179          to the instruments database
180        - added support for handling lost files in the instruments database
181        - Implemented option for adding instruments in separate directories
182          in the instruments database
183          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
184        - work-around for missing fnmatch function on Windows to make
185          instrument database compilable
186        - added instrument database support on Windows
187          works with both standalone mode and VST plugin.
188          the instruments DB file is located in
189          %USERPROFILE%\.linuxsampler\instruments.db which allows different
190          databases for each windows user
191          if no DB is present it automatically creates the .linuxsampler subdir
192          and then creates an empty DB
193        - fixed recursive import, which was broken on Windows
194    
195      * Gigasampler format engine:
196        - fixed a memory leak that could happen when a channel was deleted
197          while notes were playing
198        - made it possible to load an instrument even if the audio thread
199          isn't running
200        - added partial support for the "Controller Triggered" MIDI rule,
201          enough for piano gigs with pedal noise samples
202        - minor fix: only mark FX sends as being modified if really the
203          respective FX send MIDI controller was used
204        - added support for GM global device volume SysEx message
205          (can be selected at compile time to either apply globally to the
206          whole sampler [default] or only to the sampler channels that are
207          connected to the respective MIDI input port the SysEx message arrived
208          on)
209        - bugfix: notes triggered at position 0 in the audio buffer were
210          sometimes wrongly killed in the same buffer, causing no sound to
211          be played
212        - added support for chromatic / drumkit mode Roland GS Sysex message
213          which is usally used to switch a part between chromatic sounds and
214          drumkit sounds (as opposed to their common default setting of MIDI
215          part 10 being a drumkit part and all other ones chromatic parts), in
216          LS however one can switch between the first 16 MIDI instrument maps
217          defined for the sampler
218        - made it possible to create multiple sample channels even if the
219          audio thread isn't running
220        - fixed crash when removing channel with active voices (#116)
221        - bugfix: on sample reference changes (instrument editor), only
222          un-cache the respective sample if it's really not used by any
223          sampler engine anymore
224        - re-cache samples in case they were changed by an instrument editor,
225          e.g. when a sample was added while playing (#82)
226        - fixed hanging notes which occured when note-off event had the exact
227          same time stamp as the voice's note-on event and occured both in the
228          same audio fragment cycle (fixes bug #112)
229        - added support for the "fine tune" and "pitch bend range"
230          instrument-level gig parameters
231        - fixed minor artifacts in pitch bend handling
232        - added support for GS Reset SysEx message
233        - allow gig files to use unlimited downward pitch shifting
234        - added a limit check for upward pitch shifting
235        - bugfix: sometimes, when playing a note twice fast, the second
236          note was silent
237        - fixed crash happening when a pitch bend event arrived at the
238          same time a new instrument was loading
239    
240      * LSCP server:
241        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
242          react on MIDI data arriving on certain sampler channels (so far only
243          Note-On and Note-Off events are sent via this LSCP event)
244        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
245          react on MIDI data arriving on certain MIDI input devices (so far only
246          Note-On and Note-Off events are sent via this LSCP event)
247        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
248          SET DB_INSTRUMENT FILE_PATH
249        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
250          frontends to send MIDI messages to specific sampler channel
251        - added two additional fields to GET FILE INSTRUMENT INFO command -
252          KEY_BINDINGS and KEYSWITCH_BINDINGS
253        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
254          was incorrect
255        - Optimized the retrieval of the MIDI instrument mappings
256        - added new LSCP command "SET VOICES" to globally alter the maximum
257          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
258          be triggered respectively
259        - added new LSCP command "SET STREAMS" to globally alter the maximum
260          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
261          which will be triggered respectively
262        - bugfix: retry if "select" returns EINTR (this fixes a crash when
263          a gigedit file dialog is opened)
264        - close all connections when LSCPServer is deleted
265        - hard close of all sockets on exit
266        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
267          driver
268    
269      * Bug fixes:
270        - fixed a crash which occurs when removing a sampler channel waiting
271          to start instrument loading after another channel
272        - fixed a crash which occurs when removing a sampler channel with
273          instrument loading in progress (bug #113)
274        - fixed termination caused by uncaught exception when adding MIDI
275          instrument with PERSISTENT load mode
276        - fixed possible iterator invalidations when resetting the sampler
277        - fixed memory leaks when issuing the following LSCP commands:
278          GET AUDIO_OUTPUT_DRIVER INFO
279          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
280          GET MIDI_INPUT_DRIVER INFO
281          GET MIDI_INPUT_DRIVER_PARAMETER INFO
282        - fixed possible compilation error when sqlite is not present
283        - fixed orphaned pointers when setting maximum voices limit (bug #118)
284        - fixed crash when changing the audio output device of a sampler
285          channel with loaded instrument and start playing notes
286        - fixed endless loop in Engine::SuspendAll() (bug #120)
287        - fixed a low-level atomic load function that was broken on 64-bit
288          PowerPC, which probably could cause crashes on that platform
289        - fixed a memory management error which could cause a crash when a
290          plugin was unloaded
291        - bugfix: two private structs had the same name, which could cause
292          problems if the linker chose the wrong constructor
293        - fixed low-level ConditionServer usage bug that caused lockups on
294          Windows
295    
296    
297    Version 0.5.1 (6 December 2007)
298    
299      * packaging changes:
300        - added autoconf checks for pthread library
301        - added autoconf check for pthread bug found on certain NPTL-enabled
302          glibc versions (see Gentoo bug report #194076)
303        - added autoconf checks for MS Windows
304    
305      * general changes:
306        - bugfix: the thread used by an editor plugin didn't die when the
307          editor closed
308        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
309          out all the space. operator--() did not apply size_mask after
310          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
311          order to avoid problems with the _NonVolatileReader functions.
312        - bugfix: Stream.h: added a missing divide by BytesPerSample in
313          GetWriteSpace(). Since this function is currently only used in
314          the stream's qsort() compare function, it didn't trigger any
315          bugs.
316        - Resampler.h, Synthesizer.h: cubic interpolation now works in
317          24bit mode too. Faster method to read 24bit words on little
318          endian machines (x86): replaced 3 byte reads + shifts with a 1
319          unaligned 32bit read and shift
320        - experimental support for MS Windows (MIDI input via MME, AUDIO
321          output via ASIO)
322        - made handling of SIGINT signal (Ctrl-C) a bit more robust
323        - support for monitoring the total number of active disk streams
324          (new LSCP commands: GET TOTAL_STREAM_COUNT,
325          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
326    
327      * AUDIO driver:
328        - added Windows ASIO low latency audio driver
329    
330      * MIDI driver:
331        - added MME Windows MIDI driver
332    
333      * LSCP server:
334        - added support for Windows style path / filenames, however with
335          forward slash path separators instead of backslash
336          (i.e. "C:/foo/bar.gig")
337        - allow naughty liblscp to send non-string device parameters within
338          apostrophes as well
339        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
340          "LIST FILE INSTRUMENTS <file>" and
341          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
342          about an arbitrary instrument file on the system where the sampler is
343          running on
344    
345    Version 0.5.0 (15 October 2007)
346    
347      * packaging changes:
348        - config.h is not going to be installed along with liblinuxsampler's
349          API header files anymore
350        - only the API relevant header (and source) files will be exported to
351          the Doxygen API documentation (explicitly listed in Doxyfile.in)
352        - added completely new XCode project files for Mac OSX which is now
353          capable to execute our autoconf environment, thus no need anymore
354          to maintain the compile time configuration file (osx/version.h) for
355          OSX manually (patch by Toshi Nagata)
356        - fixed buggy boolean --enable-foo / --disable-foo configure script
357          parameters
358        - global.h now only covers global definitions that are needed for the
359          C++ API header files, all implementation internal global definitions
360          are now in global_private.h
361        - atomic.h is not exposed to the C++ API anymore
362        - no need to include config.h anymore for using LS's API header files
363        - fixed warnings in API doc generation
364    
365      * general changes:
366        - replaced the old, confusing MIDI program change mechanism by a
367          flexible MIDI instrument mapper which allows to map arbitrary
368          (MIDI bank, MIDI program) pairs with arbitrary
369          (engine type, instrument file, file index) triplets which will be
370          loaded on the respective channel when such MIDI program change
371          messages arrive, beside that, each entry allows to define a life-time
372          strategy for the instrument, so the user can define whether the
373          instrument should i.e. be permanently loaded (to be able to switch
374          quickly among sounds) or i.e. loaded just on demand when the
375          respective program change arrives (to safe RAM space), as well as a
376          global volume factor for each entry, so the user can adjust the volume
377          dynamic of his mapped instrument collection without having to modify
378          the instrument files, also one can manage arbitrary amount of such
379          MIDI instrument maps and assign each sampler channel individually
380          a certain map, so that i.e. separation of normal instruments and
381          drumkits is possible
382        - new notification events for tracking changes to audio/MIDI devices,
383          MIDI instrument maps, MIDI instruments, FX sends, global volume.
384        - sampler was limited to load max. 200 instruments in the background
385          due to a constant size RingBuffer FIFO which is now replaced by a
386          dynamic (unlimited) size std::list FIFO
387        - added FX sends, these allow to route audio signals to arbitrary audio
388          output channels for being processed by external effect processors
389          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
390          controllers
391        - global (sampler wide) volume can now be controlled at runtime
392        - Implemented new, improved notification system
393        - fixed compilation errors regarding OSX
394          (patch by Toshi Nagata)
395        - implemented instruments database
396        - added support for escape sequences to the instruments database
397        - added highly experimental support for on-the-fly instrument editing
398          within the sampler's process (by using instrument editor plugins),
399          you'll notice the new "Registered instrument editors:" message on
400          startup, added a new LSCP command:
401          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
402          to spawn a matching instrument editor for the instrument on the
403          given sampler channel, the plugin path can be overridden at compile
404          time with ./configure --enable-plugin-dir=/some/dir
405        - added experimental code for synchronizing instrument editors hosted
406          in the sampler's process to safely edit instruments while playing
407          without a crash (hopefully) by either suspending single regions
408          wherever possible or if unavoidable whole engine(s)
409        - fixed several issues in fundamental "Thread" class: set scheduling
410          policy and priority on thread level, set a minimum stack size for
411          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
412          threads simply inherited properties of starting thread instead of
413          setting their own policy and priority
414        - minor fix in our automatic stack trace mechanism on crashes, the
415          main process did not wait for the stack trace process to finish
416          its output
417        - fixed some minor memory leaks
418        - reenabled assembly features support, at the moment only for
419          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
420        - minor assembly fix in x86 features detection (don't use the PIC
421          register, to avoid relocations in the text segment at runtime)
422        - POSIX callback functions of Thread.h are hidden
423    
424      * MIDI driver:
425        - dispatch bank select (MSB and LSB) messages
426    
427      * audio driver:
428        - the ALSA audio output driver parameters now reflect the correct
429          parameter value ranges for the respective selected sound card
430          (patch by Till Wimmer, a bit fixed and extended)
431    
432      * Gigasampler format engine:
433        - if a filter is used and EG2 finishes before EG1, let the voice
434          die when EG2 has finished (this fixes a problem with clicks and
435          voice starvation for some gigs)
436        - playback is no longer disabled during instrument loading
437        - all notes playing on a channel that changes its instrument keep
438          playing with the old instrument until they get a note off
439          command
440        - EG fix: a release value of zero could cause noises or crash
441        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
442        - EG fine tuning: when attack is zero the EG starts at a level
443          above max sustain level, which means that there is a decay phase
444          even if sustain is 100%
445        - more EG fixes: the level could sometimes go below zero and cause
446          noises or crashes
447        - minor fix of EGDecay (patch by Toshi Nagata)
448        - fixed compiler error when --enable-override-filter-type was
449          supplied to the configure script (fixes #46)
450        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
451          instead of a fix value
452        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
453          127 (solo mode) only kill voices if the respective mode really
454          changed
455    
456      * LSCP server:
457        - fixed compile time error for old Bison versions
458          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
459        - parser now supports extended ASCII character set
460          (up to ASCII code 255, i.e. includes now umlauts and accents)
461        - filename arguments in LSCP commands now allow to use escape
462          sequences, that is directly literal as one of: \', \", \\, \n, \r,
463          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
464          code value like \xf2) (fixes bug #24)
465        - the following LSCP commands now also support escape sequences for at
466          least one of their text-based parameters (i.e. name, description):
467          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
468          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
469          "SET DB_INSTRUMENT_DIRECTORY NAME",
470          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
471          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
472          "FIND DB_INSTRUMENT_DIRECTORIES"
473        - returns verbose syntax errors (line and column where syntax error
474          occured, the unexpected character and the actually expected, possible
475          character(s), the latter only if less than 5 possibilities)
476        - made sure that LSCP syntax is not affected by gigedit locale
477          settings
478        - bugfix regarding strings parameter lists: all comma separated lists
479          of strings were treated as being one string containing commas
480          (fixes #57)
481    
482      * Bug fixes:
483        - fixed crash occurring on certain LSCP scripts (Bug 39)
484        - another thread safety fix for lscp "load engine" and "set
485          channel audio output device"
486        - fixed a crash which occurs when reassigning the same engine
487          on a sampler channel with connected MIDI device
488        - fixed a crash which occurs when changing the number of ports of a MIDI
489          device connected to a sampler channel to number less then or equal
490          to the index of the port to which the sampler channel is connected.
491        - The previous bindings were not been disconnected when altering
492          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
493          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
494        - The active stream/voice count statistic was incorrect.
495        - notification events were not been sent for some sampler
496          channel changes
497        - added default min and max values to restrict the number of allowed
498          audio output channels and MIDI input ports
499        - the connection to the PCM interface is now closed when destroying
500          an audio output device
501        - files with slash in their path or filename could not be loaded
502    
503      * test cases:
504        - updated and fixed (haven't been touched in a while)
505
