# Line 1  Line 1 
1  Version CVS HEAD (?)  Version 1.0.0 (30 July 2009)
3      * packaging changes:
4        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5          causing e.g. the libgig test to fail when
6          "./configure --disable-jack-driver" was used
7          (patch by Alexis Ballier)
8        - fixed compilation with gcc 4.3
9        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10        - fixed configure so it detects x86_64 (#107)
11        - fixes for building with newer MinGW versions
12        - fix for building with bison 2.4 (#111)
13        - fixed building with libgig installed in a non-standard directory
14        - minor fix in configure for mmsystem.h detection on MinGW
15        - Windows: look for editor plugins and Fantasia using base
16          directory of liblinuxsampler dll (look in the same directory and one
17          directory above)
18        - configure script fix: removed unconditional use of SSE
19        - fixed building with sqlite installed in a non-standard directory
20        - when cross-compiling, don't try to create instruments.db
21        - fix for new mingw-w64 version, which has usleep
23      * general changes:
24        - bugfix: on some POSIX systems instrument editor plugins refused to
25          load as we used a non-portable Linux specific struct field
26          (fixes bug #70, patch by Ronald Baljeu)
27        - fixed endless loop which occured when loading an instrument editor
28          plugin DLL on Windows systems failed
29        - fixed memory leaks that occurred when liblinuxsampler was unloaded
30        - optimized the SynchronizedConfig class so it doesn't wait
31          unnecessarily long after an update
32        - added support for notifying instrument editors on note-on / note-off
33          events (e.g. to highlight the pressed keys on the virtual keyboard
34          of gigedit)
35        - added support for triggering notes by instrument editors (see above)
36        - be verbose on DLL load errors (on Linux)
37        - fixed di-harmonic triangle LFO implementation (this LFO implementation
38          is only used by very few systems, most pick the int math
39          implementation, which is usually faster)
40        - fixes for audio drivers with varying buffer sizes
41        - experimental support for running LinuxSampler as a DSSI, LV2 and
42          VST plugin
43        - notification events for stream/voice count statistics are now sent
44          only when there are actual changes
45        - added memory ordering constraints to improve stability on
46          multi-core and multi-cpu systems
47        - maximum voices and disk streams can now be altered at runtime
48        - fixed CPU feature detection on x86_64 (maybe fixes #108)
49        - automatic stacktrace mechanism is now turned off by default and can
50          be switched on by command line option "--stacktrace" (the automatic
51          stacktrace mechanism seems to be broken on most systems at the moment)
52        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
53          a pointer to the launched InstrumentEditor object
54        - added optional 3rd party user data parameter for following
55          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
56          InstrumentEditor::Launch(),
57          InstrumentManager::LaunchInstrumentEditor()
58        - theoretical fix: made SynchronizedConfig follow C++0x memory
59          model more strictly
60        - fixes for using large audio device buffers
61        - Windows: add the installation directory to the DLL search path
62          when loading an editor plugin (solves problems with VST and
63          gigedit on systems with other GTK versions installed)
65      * audio driver:
66        - removed the nonsense audio channel constraint (which was hard coded to
67          max. 100 audio channels) for most audio drivers
68        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
69          opposed to the LSCP specs
70        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
71          reflected the wrong value
72        - fixed a memory management bug in ASIO driver
73        - Makefile fix: JACK_CFLAGS wasn't used
74        - JACK: use jack_client_open instead of the deprecated
75          jack_client_new
76        - added (experimental) CoreAudio driver
77        - applied old fixes to the ASIO driver that were included in the
78          previous binary release but accidentally never committed to CVS
79          (fixes #117)
80        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
81          win64)
82        - VST: added support for sample rate and buffer size changes
83        - VST: close editor (Fantasia) when the VST is removed
84        - VST: avoid opening Fantasia more than once for each VST instance
85        - VST: export main function as "main" on Linux too (fix for
86          energyXT)
87        - VST: changed number of output channels from one stereo to 16
88          stereo
89        - added channel routing, fxsends and midi maps to the settings
90          stored in the plugin state
91        - performance optimization of AudioChannel::MixTo() and
92          AudioChannel::CopyTo() methods using GCC vector exensions
93          (if available)
94        - ASIO fixes: avoid initializing the device twice, avoid throwing
95          exception when getting parameters from a disconnected device
97      * MIDI driver:
98        - added JACK MIDI driver
99        - dispatch bank select as ordinary CC as well, the user might seriously
100          want to (mis)use it for some purpose ("fixed" in all current MIDI
101          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
102        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
103          CoreMidi or AU
104        - fixed mingw-w64 compilation error in MME driver
105        - made program change handling in MIDI thread real-time safe by
106          moving the logic to a non-RT thread
107        - fixed minor memory leak in ALSA driver
109      * instruments database:
110        - avoid time consuming samples scanning when adding instruments
111          to the instruments database
112        - added support for handling lost files in the instruments database
113        - Implemented option for adding instruments in separate directories
114          in the instruments database
115          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
116        - work-around for missing fnmatch function on Windows to make
117          instrument database compilable
118        - added instrument database support on Windows
119          works with both standalone mode and VST plugin.
120          the instruments DB file is located in
121          %USERPROFILE%\.linuxsampler\instruments.db which allows different
122          databases for each windows user
123          if no DB is present it automatically creates the .linuxsampler subdir
124          and then creates an empty DB
125        - fixed recursive import, which was broken on Windows
127      * Gigasampler format engine:
128        - fixed a memory leak that could happen when a channel was deleted
129          while notes were playing
130        - made it possible to load an instrument even if the audio thread
131          isn't running
132        - added partial support for the "Controller Triggered" MIDI rule,
133          enough for piano gigs with pedal noise samples
134        - minor fix: only mark FX sends as being modified if really the
135          respective FX send MIDI controller was used
136        - added support for GM global device volume SysEx message
137          (can be selected at compile time to either apply globally to the
138          whole sampler [default] or only to the sampler channels that are
139          connected to the respective MIDI input port the SysEx message arrived
140          on)
141        - bugfix: notes triggered at position 0 in the audio buffer were
142          sometimes wrongly killed in the same buffer, causing no sound to
143          be played
144        - added support for chromatic / drumkit mode Roland GS Sysex message
145          which is usally used to switch a part between chromatic sounds and
146          drumkit sounds (as opposed to their common default setting of MIDI
147          part 10 being a drumkit part and all other ones chromatic parts), in
148          LS however one can switch between the first 16 MIDI instrument maps
149          defined for the sampler
150        - made it possible to create multiple sample channels even if the
151          audio thread isn't running
152        - fixed crash when removing channel with active voices (#116)
153        - bugfix: on sample reference changes (instrument editor), only
154          un-cache the respective sample if it's really not used by any
155          sampler engine anymore
156        - re-cache samples in case they were changed by an instrument editor,
157          e.g. when a sample was added while playing (#82)
158        - fixed hanging notes which occured when note-off event had the exact
159          same time stamp as the voice's note-on event and occured both in the
160          same audio fragment cycle (fixes bug #112)
161        - added support for the "fine tune" and "pitch bend range"
162          instrument-level gig parameters
163        - fixed minor artifacts in pitch bend handling
164        - added support for GS Reset SysEx message
165        - allow gig files to use unlimited downward pitch shifting
166        - added a limit check for upward pitch shifting
167        - bugfix: sometimes, when playing a note twice fast, the second
168          note was silent
169        - fixed crash happening when a pitch bend event arrived at the
170          same time a new instrument was loading
172      * LSCP server:
173        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
174          react on MIDI data arriving on certain sampler channels (so far only
175          Note-On and Note-Off events are sent via this LSCP event)
176        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
177          react on MIDI data arriving on certain MIDI input devices (so far only
178          Note-On and Note-Off events are sent via this LSCP event)
179        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
181        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
182          frontends to send MIDI messages to specific sampler channel
183        - added two additional fields to GET FILE INSTRUMENT INFO command -
185        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
186          was incorrect
187        - Optimized the retrieval of the MIDI instrument mappings
188        - added new LSCP command "SET VOICES" to globally alter the maximum
189          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
190          be triggered respectively
191        - added new LSCP command "SET STREAMS" to globally alter the maximum
192          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
193          which will be triggered respectively
194        - bugfix: retry if "select" returns EINTR (this fixes a crash when
195          a gigedit file dialog is opened)
196        - close all connections when LSCPServer is deleted
197        - hard close of all sockets on exit
198        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
199          driver
201      * Bug fixes:
202        - fixed a crash which occurs when removing a sampler channel waiting
203          to start instrument loading after another channel
204        - fixed a crash which occurs when removing a sampler channel with
205          instrument loading in progress (bug #113)
206        - fixed termination caused by uncaught exception when adding MIDI
207          instrument with PERSISTENT load mode
208        - fixed possible iterator invalidations when resetting the sampler
209        - fixed memory leaks when issuing the following LSCP commands:
214        - fixed possible compilation error when sqlite is not present
215        - fixed orphaned pointers when setting maximum voices limit (bug #118)
216        - fixed crash when changing the audio output device of a sampler
217          channel with loaded instrument and start playing notes
218        - fixed endless loop in Engine::SuspendAll() (bug #120)
219        - fixed a low-level atomic load function that was broken on 64-bit
220          PowerPC, which probably could cause crashes on that platform
221        - fixed a memory management error which could cause a crash when a
222          plugin was unloaded
223        - bugfix: two private structs had the same name, which could cause
224          problems if the linker chose the wrong constructor
225        - fixed low-level ConditionServer usage bug that caused lockups on
226          Windows
229    Version 0.5.1 (6 December 2007)
231      * packaging changes:
232        - added autoconf checks for pthread library
233        - added autoconf check for pthread bug found on certain NPTL-enabled
234          glibc versions (see Gentoo bug report #194076)
235        - added autoconf checks for MS Windows
237      * general changes:
238        - bugfix: the thread used by an editor plugin didn't die when the
239          editor closed
240        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
241          out all the space. operator--() did not apply size_mask after
242          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
243          order to avoid problems with the _NonVolatileReader functions.
244        - bugfix: Stream.h: added a missing divide by BytesPerSample in
245          GetWriteSpace(). Since this function is currently only used in
246          the stream's qsort() compare function, it didn't trigger any
247          bugs.
248        - Resampler.h, Synthesizer.h: cubic interpolation now works in
249          24bit mode too. Faster method to read 24bit words on little
250          endian machines (x86): replaced 3 byte reads + shifts with a 1
251          unaligned 32bit read and shift
252        - experimental support for MS Windows (MIDI input via MME, AUDIO
253          output via ASIO)
254        - made handling of SIGINT signal (Ctrl-C) a bit more robust
255        - support for monitoring the total number of active disk streams
256          (new LSCP commands: GET TOTAL_STREAM_COUNT,
259      * AUDIO driver:
260        - added Windows ASIO low latency audio driver
262      * MIDI driver:
263        - added MME Windows MIDI driver
265      * LSCP server:
266        - added support for Windows style path / filenames, however with
267          forward slash path separators instead of backslash
268          (i.e. "C:/foo/bar.gig")
269        - allow naughty liblscp to send non-string device parameters within
270          apostrophes as well
271        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
272          "LIST FILE INSTRUMENTS <file>" and
273          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
274          about an arbitrary instrument file on the system where the sampler is
275          running on
277    Version 0.5.0 (15 October 2007)
279      * packaging changes:
280        - config.h is not going to be installed along with liblinuxsampler's
281          API header files anymore
282        - only the API relevant header (and source) files will be exported to
283          the Doxygen API documentation (explicitly listed in Doxyfile.in)
284        - added completely new XCode project files for Mac OSX which is now
285          capable to execute our autoconf environment, thus no need anymore
286          to maintain the compile time configuration file (osx/version.h) for
287          OSX manually (patch by Toshi Nagata)
288        - fixed buggy boolean --enable-foo / --disable-foo configure script
289          parameters
290        - global.h now only covers global definitions that are needed for the
291          C++ API header files, all implementation internal global definitions
292          are now in global_private.h
293        - atomic.h is not exposed to the C++ API anymore
294        - no need to include config.h anymore for using LS's API header files
295        - fixed warnings in API doc generation
297    * general changes:    * general changes:

324        - Implemented new, improved notification system
325        - fixed compilation errors regarding OSX
326          (patch by Toshi Nagata)
327        - implemented instruments database
328        - added support for escape sequences to the instruments database
329        - added highly experimental support for on-the-fly instrument editing
330          within the sampler's process (by using instrument editor plugins),
331          you'll notice the new "Registered instrument editors:" message on
332          startup, added a new LSCP command:
333          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
334          to spawn a matching instrument editor for the instrument on the
335          given sampler channel, the plugin path can be overridden at compile
336          time with ./configure --enable-plugin-dir=/some/dir
337        - added experimental code for synchronizing instrument editors hosted
338          in the sampler's process to safely edit instruments while playing
339          without a crash (hopefully) by either suspending single regions
340          wherever possible or if unavoidable whole engine(s)
341        - fixed several issues in fundamental "Thread" class: set scheduling
342          policy and priority on thread level, set a minimum stack size for
343          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
344          threads simply inherited properties of starting thread instead of
345          setting their own policy and priority
346        - minor fix in our automatic stack trace mechanism on crashes, the
347          main process did not wait for the stack trace process to finish
348          its output
349        - fixed some minor memory leaks
350        - reenabled assembly features support, at the moment only for
351          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
352        - minor assembly fix in x86 features detection (don't use the PIC
353          register, to avoid relocations in the text segment at runtime)
354        - POSIX callback functions of Thread.h are hidden
356    * MIDI driver:    * MIDI driver:
357      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages

376        even if sustain is 100%        even if sustain is 100%
377        - more EG fixes: the level could sometimes go below zero and cause
378          noises or crashes
379        - minor fix of EGDecay (patch by Toshi Nagata)
380        - fixed compiler error when --enable-override-filter-type was
381          supplied to the configure script (fixes #46)
382        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
383          instead of a fix value
384        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
385          127 (solo mode) only kill voices if the respective mode really
386          changed
388      * LSCP server:
389        - fixed compile time error for old Bison versions
390          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
391        - parser now supports extended ASCII character set
392          (up to ASCII code 255, i.e. includes now umlauts and accents)
393        - filename arguments in LSCP commands now allow to use escape
394          sequences, that is directly literal as one of: \', \", \\, \n, \r,
395          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
396          code value like \xf2) (fixes bug #24)
397        - the following LSCP commands now also support escape sequences for at
398          least one of their text-based parameters (i.e. name, description):
405        - returns verbose syntax errors (line and column where syntax error
406          occured, the unexpected character and the actually expected, possible
407          character(s), the latter only if less than 5 possibilities)
408        - made sure that LSCP syntax is not affected by gigedit locale
409          settings
410        - bugfix regarding strings parameter lists: all comma separated lists
411          of strings were treated as being one string containing commas
412          (fixes #57)
414    * Bug fixes:    * Bug fixes:
415      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
416      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
417        channel audio output device"        channel audio output device"
418        - fixed a crash which occurs when reassigning the same engine
419          on a sampler channel with connected MIDI device
420        - fixed a crash which occurs when changing the number of ports of a MIDI
421          device connected to a sampler channel to number less then or equal
422          to the index of the port to which the sampler channel is connected.
423        - The previous bindings were not been disconnected when altering
424          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
425          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
426        - The active stream/voice count statistic was incorrect.
