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