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