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    
14      * general changes:
15        - bugfix: on some POSIX systems instrument editor plugins refused to
16          load as we used a non-portable Linux specific struct field
17          (fixes bug #70, patch by Ronald Baljeu)
18        - fixed endless loop which occured when loading an instrument editor
19          plugin DLL on Windows systems failed
20        - fixed memory leaks that occurred when liblinuxsampler was unloaded
21        - optimized the SynchronizedConfig class so it doesn't wait
22          unnecessarily long after an update
23        - added support for notifying instrument editors on note-on / note-off
24          events (e.g. to highlight the pressed keys on the virtual keyboard
25          of gigedit)
26        - added support for triggering notes by instrument editors (see above)
27        - be verbose on DLL load errors (on Linux)
28        - fixed di-harmonic triangle LFO implementation (this LFO implementation
29          is only used by very few systems, most pick the int math
30          implementation, which is usually faster)
31        - fixes for audio drivers with varying buffer sizes
32        - experimental support for running LinuxSampler as a DSSI, LV2 and
33          VST plugin
34        - notification events for stream/voice count statistics are now sent
35          only when there are actual changes
36        - added memory ordering constraints to improve stability on
37          multi-core and multi-cpu systems
38        - maximum voices and disk streams can now be altered at runtime
39        - fixed CPU feature detection on x86_64 (maybe fixes #108)
40    
41      * audio driver:
42        - removed the nonsense audio channel constraint (which was hard coded to
43          max. 100 audio channels) for most audio drivers
44        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
45          opposed to the LSCP specs
46        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
47          reflected the wrong value
48        - fixed a memory management bug in ASIO driver
49        - Makefile fix: JACK_CFLAGS wasn't used
50        - JACK: use jack_client_open instead of the deprecated
51          jack_client_new
52    
53      * MIDI driver:
54        - added JACK MIDI driver
55        - dispatch bank select as ordinary CC as well, the user might seriously
56          want to (mis)use it for some purpose ("fixed" in all current MIDI
57          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
58    
59      * instruments database:
60        - avoid time consuming samples scanning when adding instruments
61          to the instruments database
62        - added support for handling lost files in the instruments database
63        - Implemented option for adding instruments in separate directories
64          in the instruments database
65          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
66    
67      * Gigasampler format engine:
68        - fixed a memory leak that could happen when a channel was deleted
69          while notes were playing
70        - made it possible to load an instrument even if the audio thread
71          isn't running
72        - added partial support for the "Controller Triggered" MIDI rule,
73          enough for piano gigs with pedal noise samples
74        - minor fix: only mark FX sends as being modified if really the
75          respective FX send MIDI controller was used
76        - added support for GM global device volume SysEx message
77          (can be selected at compile time to either apply globally to the
78          whole sampler [default] or only to the sampler channels that are
79          connected to the respective MIDI input port the SysEx message arrived
80          on)
81        - bugfix: notes triggered at position 0 in the audio buffer were
82          sometimes wrongly killed in the same buffer, causing no sound to
83          be played
84        - added support for chromatic / drumkit mode Roland GS Sysex message
85          which is usally used to switch a part between chromatic sounds and
86          drumkit sounds (as opposed to their common default setting of MIDI
87          part 10 being a drumkit part and all other ones chromatic parts), in
88          LS however one can switch between the first 16 MIDI instrument maps
89          defined for the sampler
90        - made it possible to create multiple sample channels even if the
91          audio thread isn't running
92    
93      * LSCP server:
94        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
95          react on MIDI data arriving on certain sampler channels (so far only
96          Note-On and Note-Off events are sent via this LSCP event)
97        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
98          react on MIDI data arriving on certain MIDI input devices (so far only
99          Note-On and Note-Off events are sent via this LSCP event)
100        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
101          SET DB_INSTRUMENT FILE_PATH
102        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
103          frontends to send MIDI messages to specific sampler channel
104        - added two additional fields to GET FILE INSTRUMENT INFO command -
105          KEY_BINDINGS and KEYSWITCH_BINDINGS
106        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
107          was incorrect
108        - Optimized the retrieval of the MIDI instrument mappings
109        - added new LSCP command "SET VOICES" to globally alter the maximum
110          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
111          be triggered respectively
112        - added new LSCP command "SET STREAMS" to globally alter the maximum
113          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
114          which will be triggered respectively
115        - bugfix: retry if "select" returns EINTR (this fixes a crash when
116          a gigedit file dialog is opened)
117    
118      * Bug fixes:
119        - fixed a crash which occurs when removing a sampler channel waiting
120          to start instrument loading after another channel
121    
122    
123    Version 0.5.1 (6 December 2007)
124    
125      * packaging changes:
126        - added autoconf checks for pthread library
127        - added autoconf check for pthread bug found on certain NPTL-enabled
128          glibc versions (see Gentoo bug report #194076)
129        - added autoconf checks for MS Windows
130    
131      * general changes:
132        - bugfix: the thread used by an editor plugin didn't die when the
133          editor closed
134        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
135          out all the space. operator--() did not apply size_mask after
136          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
137          order to avoid problems with the _NonVolatileReader functions.
138        - bugfix: Stream.h: added a missing divide by BytesPerSample in
139          GetWriteSpace(). Since this function is currently only used in
140          the stream's qsort() compare function, it didn't trigger any
141          bugs.
142        - Resampler.h, Synthesizer.h: cubic interpolation now works in
143          24bit mode too. Faster method to read 24bit words on little
144          endian machines (x86): replaced 3 byte reads + shifts with a 1
145          unaligned 32bit read and shift
146        - experimental support for MS Windows (MIDI input via MME, AUDIO
147          output via ASIO)
148        - made handling of SIGINT signal (Ctrl-C) a bit more robust
149        - support for monitoring the total number of active disk streams
150          (new LSCP commands: GET TOTAL_STREAM_COUNT,
151          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
152    
153      * AUDIO driver:
154        - added Windows ASIO low latency audio driver
155    
156      * MIDI driver:
157        - added MME Windows MIDI driver
158    
159      * LSCP server:
160        - added support for Windows style path / filenames, however with
161          forward slash path separators instead of backslash
162          (i.e. "C:/foo/bar.gig")
163        - allow naughty liblscp to send non-string device parameters within
164          apostrophes as well
165        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
166          "LIST FILE INSTRUMENTS <file>" and
167          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
168          about an arbitrary instrument file on the system where the sampler is
169          running on
170    
171    Version 0.5.0 (15 October 2007)
172    
173      * packaging changes:
174        - config.h is not going to be installed along with liblinuxsampler's
175          API header files anymore
176      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to
177        the Doxygen API documentation (explicitly listed in Doxyfile.in)        the Doxygen API documentation (explicitly listed in Doxyfile.in)
178        - added completely new XCode project files for Mac OSX which is now
179          capable to execute our autoconf environment, thus no need anymore
180          to maintain the compile time configuration file (osx/version.h) for
181          OSX manually (patch by Toshi Nagata)
182        - fixed buggy boolean --enable-foo / --disable-foo configure script
183          parameters
184        - global.h now only covers global definitions that are needed for the
185          C++ API header files, all implementation internal global definitions
186          are now in global_private.h
187        - atomic.h is not exposed to the C++ API anymore
188        - no need to include config.h anymore for using LS's API header files
189        - fixed warnings in API doc generation
190    
191    * general changes:    * general changes:

217      - global (sampler wide) volume can now be controlled at runtime      - global (sampler wide) volume can now be controlled at runtime
218      - Implemented new, improved notification system      - Implemented new, improved notification system
219        - fixed compilation errors regarding OSX
220          (patch by Toshi Nagata)
221        - implemented instruments database
222        - added support for escape sequences to the instruments database
223        - added highly experimental support for on-the-fly instrument editing
224          within the sampler's process (by using instrument editor plugins),
225          you'll notice the new "Registered instrument editors:" message on
226          startup, added a new LSCP command:
227          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
228          to spawn a matching instrument editor for the instrument on the
229          given sampler channel, the plugin path can be overridden at compile
230          time with ./configure --enable-plugin-dir=/some/dir
231        - added experimental code for synchronizing instrument editors hosted
232          in the sampler's process to safely edit instruments while playing
233          without a crash (hopefully) by either suspending single regions
234          wherever possible or if unavoidable whole engine(s)
235        - fixed several issues in fundamental "Thread" class: set scheduling
236          policy and priority on thread level, set a minimum stack size for
237          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
238          threads simply inherited properties of starting thread instead of
239          setting their own policy and priority
240        - minor fix in our automatic stack trace mechanism on crashes, the
241          main process did not wait for the stack trace process to finish
242          its output
243        - fixed some minor memory leaks
244        - reenabled assembly features support, at the moment only for
245          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
246        - minor assembly fix in x86 features detection (don't use the PIC
247          register, to avoid relocations in the text segment at runtime)
248        - POSIX callback functions of Thread.h are hidden
249    
250    * MIDI driver:    * MIDI driver:
251      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages

271        - more EG fixes: the level could sometimes go below zero and cause
272          noises or crashes
273        - minor fix of EGDecay (patch by Toshi Nagata)
274        - fixed compiler error when --enable-override-filter-type was
275          supplied to the configure script (fixes #46)
276        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
277          instead of a fix value
278        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
279          127 (solo mode) only kill voices if the respective mode really
280          changed
281    
282      * LSCP server:
283        - fixed compile time error for old Bison versions
284          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
285        - parser now supports extended ASCII character set
286          (up to ASCII code 255, i.e. includes now umlauts and accents)
287        - filename arguments in LSCP commands now allow to use escape
288          sequences, that is directly literal as one of: \', \", \\, \n, \r,
289          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
290          code value like \xf2) (fixes bug #24)
291        - the following LSCP commands now also support escape sequences for at
292          least one of their text-based parameters (i.e. name, description):
293          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
294          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
295          "SET DB_INSTRUMENT_DIRECTORY NAME",
296          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
297          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
298          "FIND DB_INSTRUMENT_DIRECTORIES"
299        - returns verbose syntax errors (line and column where syntax error
300          occured, the unexpected character and the actually expected, possible
301          character(s), the latter only if less than 5 possibilities)
302        - made sure that LSCP syntax is not affected by gigedit locale
303          settings
304        - bugfix regarding strings parameter lists: all comma separated lists
305          of strings were treated as being one string containing commas
306          (fixes #57)
307    
308    * Bug fixes:    * Bug fixes:
309      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
310      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
311        channel audio output device"        channel audio output device"
312        - fixed a crash which occurs when reassigning the same engine
313          on a sampler channel with connected MIDI device
314        - fixed a crash which occurs when changing the number of ports of a MIDI
315          device connected to a sampler channel to number less then or equal
316          to the index of the port to which the sampler channel is connected.
317        - The previous bindings were not been disconnected when altering
318          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
319          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
320        - The active stream/voice count statistic was incorrect.
321        - notification events were not been sent for some sampler
322          channel changes
323        - added default min and max values to restrict the number of allowed
324          audio output channels and MIDI input ports
325        - the connection to the PCM interface is now closed when destroying
326          an audio output device
327        - files with slash in their path or filename could not be loaded
328    
329      * test cases:
330        - updated and fixed (haven't been touched in a while)
