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