1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3    * packaging changes:    * 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
17        - configure script fix: removed unconditional use of SSE
18    
19      * general changes:
20        - bugfix: on some POSIX systems instrument editor plugins refused to
21          load as we used a non-portable Linux specific struct field
22          (fixes bug #70, patch by Ronald Baljeu)
23        - fixed endless loop which occured when loading an instrument editor
24          plugin DLL on Windows systems failed
25        - fixed memory leaks that occurred when liblinuxsampler was unloaded
26        - optimized the SynchronizedConfig class so it doesn't wait
27          unnecessarily long after an update
28        - added support for notifying instrument editors on note-on / note-off
29          events (e.g. to highlight the pressed keys on the virtual keyboard
30          of gigedit)
31        - added support for triggering notes by instrument editors (see above)
32        - be verbose on DLL load errors (on Linux)
33        - fixed di-harmonic triangle LFO implementation (this LFO implementation
34          is only used by very few systems, most pick the int math
35          implementation, which is usually faster)
36        - fixes for audio drivers with varying buffer sizes
37        - experimental support for running LinuxSampler as a DSSI, LV2 and
38          VST plugin
39        - notification events for stream/voice count statistics are now sent
40          only when there are actual changes
41        - added memory ordering constraints to improve stability on
42          multi-core and multi-cpu systems
43        - maximum voices and disk streams can now be altered at runtime
44        - fixed CPU feature detection on x86_64 (maybe fixes #108)
45        - automatic stacktrace mechanism is now turned off by default and can
46          be switched on by command line option "--stacktrace" (the automatic
47          stacktrace mechanism seems to be broken on most systems at the moment)
48        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
49          a pointer to the launched InstrumentEditor object
50        - added optional 3rd party user data parameter for following
51          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
52          InstrumentEditor::Launch(),
53          InstrumentManager::LaunchInstrumentEditor()
54        - theoretical fix: made SynchronizedConfig follow C++0x memory
55          model more strictly
56        - fixes for using large audio device buffers
57    
58      * audio driver:
59        - removed the nonsense audio channel constraint (which was hard coded to
60          max. 100 audio channels) for most audio drivers
61        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
62          opposed to the LSCP specs
63        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
64          reflected the wrong value
65        - fixed a memory management bug in ASIO driver
66        - Makefile fix: JACK_CFLAGS wasn't used
67        - JACK: use jack_client_open instead of the deprecated
68          jack_client_new
69        - added (experimental) CoreAudio driver
70        - applied old fixes to the ASIO driver that were included in the
71          previous binary release but accidentally never committed to CVS
72          (fixes #117)
73        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
74          win64)
75        - VST: added support for sample rate and buffer size changes
76        - VST: close editor (Fantasia) when the VST is removed
77        - VST: avoid opening Fantasia more than once for each VST instance
78        - VST: export main function as "main" on Linux too (fix for
79          energyXT)
80        - VST: changed number of output channels from one stereo to 16
81          stereo
82    
83      * MIDI driver:
84        - added JACK MIDI driver
85        - dispatch bank select as ordinary CC as well, the user might seriously
86          want to (mis)use it for some purpose ("fixed" in all current MIDI
87          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
88        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
89          CoreMidi or AU
90        - fixed mingw-w64 compilation error in MME driver
91    
92      * instruments database:
93        - avoid time consuming samples scanning when adding instruments
94          to the instruments database
95        - added support for handling lost files in the instruments database
96        - Implemented option for adding instruments in separate directories
97          in the instruments database
98          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
99        - work-around for missing fnmatch function on Windows to make
100          instrument database compilable
101            - added instrument database support on Windows
102              works with both standalone mode and VST plugin.
103              the instruments DB file is located in
104              %USERPROFILE%\.linuxsampler\instruments.db which allows different
105              databases for each windows user
106              if no DB is present it automatically creates the .linuxsampler subdir
107              and then creates an empty DB
108    
109      * Gigasampler format engine:
110        - fixed a memory leak that could happen when a channel was deleted
111          while notes were playing
112        - made it possible to load an instrument even if the audio thread
113          isn't running
114        - added partial support for the "Controller Triggered" MIDI rule,
115          enough for piano gigs with pedal noise samples
116        - minor fix: only mark FX sends as being modified if really the
117          respective FX send MIDI controller was used
118        - added support for GM global device volume SysEx message
119          (can be selected at compile time to either apply globally to the
120          whole sampler [default] or only to the sampler channels that are
121          connected to the respective MIDI input port the SysEx message arrived
122          on)
123        - bugfix: notes triggered at position 0 in the audio buffer were
124          sometimes wrongly killed in the same buffer, causing no sound to
125          be played
126        - added support for chromatic / drumkit mode Roland GS Sysex message
127          which is usally used to switch a part between chromatic sounds and
128          drumkit sounds (as opposed to their common default setting of MIDI
129          part 10 being a drumkit part and all other ones chromatic parts), in
130          LS however one can switch between the first 16 MIDI instrument maps
131          defined for the sampler
132        - made it possible to create multiple sample channels even if the
133          audio thread isn't running
134        - fixed crash when removing channel with active voices (#116)
135        - bugfix: on sample reference changes (instrument editor), only
136          un-cache the respective sample if it's really not used by any
137          sampler engine anymore
138        - re-cache samples in case they were changed by an instrument editor,
139          e.g. when a sample was added while playing (#82)
140        - fixed hanging notes which occured when note-off event had the exact
141          same time stamp as the voice's note-on event and occured both in the
142          same audio fragment cycle (fixes bug #112)
143        - added support for the "fine tune" and "pitch bend range"
144          instrument-level gig parameters
145        - fixed minor artifacts in pitch bend handling
146        - added support for GS Reset SysEx message
147        - allow gig files to use unlimited downward pitch shifting
148        - added a limit check for upward pitch shifting
149        - bugfix: sometimes, when playing a note twice fast, the second
150          note was silent
151    
152      * LSCP server:
153        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
154          react on MIDI data arriving on certain sampler channels (so far only
155          Note-On and Note-Off events are sent via this LSCP event)
156        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
157          react on MIDI data arriving on certain MIDI input devices (so far only
158          Note-On and Note-Off events are sent via this LSCP event)
159        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
160          SET DB_INSTRUMENT FILE_PATH
161        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
162          frontends to send MIDI messages to specific sampler channel
163        - added two additional fields to GET FILE INSTRUMENT INFO command -
164          KEY_BINDINGS and KEYSWITCH_BINDINGS
165        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
166          was incorrect
167        - Optimized the retrieval of the MIDI instrument mappings
168        - added new LSCP command "SET VOICES" to globally alter the maximum
169          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
170          be triggered respectively
171        - added new LSCP command "SET STREAMS" to globally alter the maximum
172          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
173          which will be triggered respectively
174        - bugfix: retry if "select" returns EINTR (this fixes a crash when
175          a gigedit file dialog is opened)
176        - close all connections when LSCPServer is deleted
177        - hard close of all sockets on exit
178        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
179          driver
180    
181      * Bug fixes:
182        - fixed a crash which occurs when removing a sampler channel waiting
183          to start instrument loading after another channel
184        - fixed a crash which occurs when removing a sampler channel with
185          instrument loading in progress (bug #113)
186        - fixed termination caused by uncaught exception when adding MIDI
187          instrument with PERSISTENT load mode
188        - fixed possible iterator invalidations when resetting the sampler
189        - fixed memory leaks when issuing the following LSCP commands:
190          GET AUDIO_OUTPUT_DRIVER INFO
191          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
192          GET MIDI_INPUT_DRIVER INFO
193          GET MIDI_INPUT_DRIVER_PARAMETER INFO
194        - fixed possible compilation error when sqlite is not present
195        - fixed orphaned pointers when setting maximum voices limit (bug #118)
196        - fixed crash when changing the audio output device of a sampler
197          channel with loaded instrument and start playing notes
198        - fixed endless loop in Engine::SuspendAll() (bug #120)
199        - fixed a low-level atomic load function that was broken on 64-bit
200          PowerPC, which probably could cause crashes on that platform
201        - fixed a memory management error which could cause a crash when a
202          plugin was unloaded
203        - bugfix: two private structs had the same name, which could cause
204          problems if the linker chose the wrong constructor
205    
206    
207    Version 0.5.1 (6 December 2007)
208    
209      * packaging changes:
210        - added autoconf checks for pthread library
211        - added autoconf check for pthread bug found on certain NPTL-enabled
212          glibc versions (see Gentoo bug report #194076)
213        - added autoconf checks for MS Windows
214    
215      * general changes:
216        - bugfix: the thread used by an editor plugin didn't die when the
217          editor closed
218        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
219          out all the space. operator--() did not apply size_mask after
220          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
221          order to avoid problems with the _NonVolatileReader functions.
222        - bugfix: Stream.h: added a missing divide by BytesPerSample in
223          GetWriteSpace(). Since this function is currently only used in
224          the stream's qsort() compare function, it didn't trigger any
225          bugs.
226        - Resampler.h, Synthesizer.h: cubic interpolation now works in
227          24bit mode too. Faster method to read 24bit words on little
228          endian machines (x86): replaced 3 byte reads + shifts with a 1
229          unaligned 32bit read and shift
230        - experimental support for MS Windows (MIDI input via MME, AUDIO
231          output via ASIO)
232        - made handling of SIGINT signal (Ctrl-C) a bit more robust
233        - support for monitoring the total number of active disk streams
234          (new LSCP commands: GET TOTAL_STREAM_COUNT,
235          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
236    
237      * AUDIO driver:
238        - added Windows ASIO low latency audio driver
239    
240      * MIDI driver:
241        - added MME Windows MIDI driver
242    
243      * LSCP server:
244        - added support for Windows style path / filenames, however with
245          forward slash path separators instead of backslash
246          (i.e. "C:/foo/bar.gig")
247        - allow naughty liblscp to send non-string device parameters within
248          apostrophes as well
249        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
250          "LIST FILE INSTRUMENTS <file>" and
251          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
252          about an arbitrary instrument file on the system where the sampler is
253          running on
254    
255    Version 0.5.0 (15 October 2007)
256    
257      * packaging changes:
258        - config.h is not going to be installed along with liblinuxsampler's
259          API header files anymore
260      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to
261        the Doxygen API documentation (explicitly listed in Doxyfile.in)        the Doxygen API documentation (explicitly listed in Doxyfile.in)
262        - added completely new XCode project files for Mac OSX which is now
263          capable to execute our autoconf environment, thus no need anymore
264          to maintain the compile time configuration file (osx/version.h) for
265          OSX manually (patch by Toshi Nagata)
266        - fixed buggy boolean --enable-foo / --disable-foo configure script
267          parameters
268        - global.h now only covers global definitions that are needed for the
269          C++ API header files, all implementation internal global definitions
270          are now in global_private.h
271        - atomic.h is not exposed to the C++ API anymore
272        - no need to include config.h anymore for using LS's API header files
273        - fixed warnings in API doc generation
274    
275    * general changes:    * general changes:
276      - replaced the old, confusing MIDI program change mechanism by a      - replaced the old, confusing MIDI program change mechanism by a

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

355        - more EG fixes: the level could sometimes go below zero and cause
356          noises or crashes
357        - minor fix of EGDecay (patch by Toshi Nagata)
358        - fixed compiler error when --enable-override-filter-type was
359          supplied to the configure script (fixes #46)
360        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
361          instead of a fix value
362        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
363          127 (solo mode) only kill voices if the respective mode really
364          changed
365    
366      * LSCP server:
367        - fixed compile time error for old Bison versions
368          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
369        - parser now supports extended ASCII character set
370          (up to ASCII code 255, i.e. includes now umlauts and accents)
371        - filename arguments in LSCP commands now allow to use escape
372          sequences, that is directly literal as one of: \', \", \\, \n, \r,
373          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
374          code value like \xf2) (fixes bug #24)
375        - the following LSCP commands now also support escape sequences for at
376          least one of their text-based parameters (i.e. name, description):
377          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
378          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
379          "SET DB_INSTRUMENT_DIRECTORY NAME",
380          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
381          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
382          "FIND DB_INSTRUMENT_DIRECTORIES"
383        - returns verbose syntax errors (line and column where syntax error
384          occured, the unexpected character and the actually expected, possible
385          character(s), the latter only if less than 5 possibilities)
386        - made sure that LSCP syntax is not affected by gigedit locale
387          settings
388        - bugfix regarding strings parameter lists: all comma separated lists
389          of strings were treated as being one string containing commas
390          (fixes #57)
391    
392    * Bug fixes:    * Bug fixes:
393      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
394      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
395        channel audio output device"        channel audio output device"
396        - fixed a crash which occurs when reassigning the same engine
397          on a sampler channel with connected MIDI device
398        - fixed a crash which occurs when changing the number of ports of a MIDI
399          device connected to a sampler channel to number less then or equal
400          to the index of the port to which the sampler channel is connected.
401        - The previous bindings were not been disconnected when altering
402          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
403          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
404        - The active stream/voice count statistic was incorrect.
405        - notification events were not been sent for some sampler
406          channel changes
407        - added default min and max values to restrict the number of allowed
408          audio output channels and MIDI input ports
409        - the connection to the PCM interface is now closed when destroying
410          an audio output device
411        - files with slash in their path or filename could not be loaded
412    
413      * test cases:
414        - updated and fixed (haven't been touched in a while)
