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        - automatic stacktrace mechanism is now turned off by default and can
41          be switched on by command line option "--stacktrace" (the automatic
42          stacktrace mechanism seems to be broken on most systems at the moment)
43    
44      * audio driver:
45        - removed the nonsense audio channel constraint (which was hard coded to
46          max. 100 audio channels) for most audio drivers
47        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
48          opposed to the LSCP specs
49        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
50          reflected the wrong value
51        - fixed a memory management bug in ASIO driver
52        - Makefile fix: JACK_CFLAGS wasn't used
53        - JACK: use jack_client_open instead of the deprecated
54          jack_client_new
55        - added (experimental) CoreAudio driver
56    
57      * MIDI driver:
58        - added JACK MIDI driver
59        - dispatch bank select as ordinary CC as well, the user might seriously
60          want to (mis)use it for some purpose ("fixed" in all current MIDI
61          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
62    
63      * instruments database:
64        - avoid time consuming samples scanning when adding instruments
65          to the instruments database
66        - added support for handling lost files in the instruments database
67        - Implemented option for adding instruments in separate directories
68          in the instruments database
69          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
70    
71      * Gigasampler format engine:
72        - fixed a memory leak that could happen when a channel was deleted
73          while notes were playing
74        - made it possible to load an instrument even if the audio thread
75          isn't running
76        - added partial support for the "Controller Triggered" MIDI rule,
77          enough for piano gigs with pedal noise samples
78        - minor fix: only mark FX sends as being modified if really the
79          respective FX send MIDI controller was used
80        - added support for GM global device volume SysEx message
81          (can be selected at compile time to either apply globally to the
82          whole sampler [default] or only to the sampler channels that are
83          connected to the respective MIDI input port the SysEx message arrived
84          on)
85        - bugfix: notes triggered at position 0 in the audio buffer were
86          sometimes wrongly killed in the same buffer, causing no sound to
87          be played
88        - added support for chromatic / drumkit mode Roland GS Sysex message
89          which is usally used to switch a part between chromatic sounds and
90          drumkit sounds (as opposed to their common default setting of MIDI
91          part 10 being a drumkit part and all other ones chromatic parts), in
92          LS however one can switch between the first 16 MIDI instrument maps
93          defined for the sampler
94        - made it possible to create multiple sample channels even if the
95          audio thread isn't running
96    
97      * LSCP server:
98        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
99          react on MIDI data arriving on certain sampler channels (so far only
100          Note-On and Note-Off events are sent via this LSCP event)
101        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
102          react on MIDI data arriving on certain MIDI input devices (so far only
103          Note-On and Note-Off events are sent via this LSCP event)
104        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
105          SET DB_INSTRUMENT FILE_PATH
106        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
107          frontends to send MIDI messages to specific sampler channel
108        - added two additional fields to GET FILE INSTRUMENT INFO command -
109          KEY_BINDINGS and KEYSWITCH_BINDINGS
110        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
111          was incorrect
112        - Optimized the retrieval of the MIDI instrument mappings
113        - added new LSCP command "SET VOICES" to globally alter the maximum
114          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
115          be triggered respectively
116        - added new LSCP command "SET STREAMS" to globally alter the maximum
117          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
118          which will be triggered respectively
119        - bugfix: retry if "select" returns EINTR (this fixes a crash when
120          a gigedit file dialog is opened)
121    
122      * Bug fixes:
123        - fixed a crash which occurs when removing a sampler channel waiting
124          to start instrument loading after another channel
125        - fixed a crash which occurs when removing a sampler channel with
126          instrument loading in progress (bug #113)
127        - fixed termination caused by uncaught exception when adding MIDI
128          instrument with PERSISTENT load mode
129        - fixed possible iterator invalidations when resetting the sampler
130        - fixed memory leaks when issuing the following LSCP commands:
131          GET AUDIO_OUTPUT_DRIVER INFO
132          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
133          GET MIDI_INPUT_DRIVER INFO
134          GET MIDI_INPUT_DRIVER_PARAMETER INFO
135        - fixed possible compilation error when sqlite is not present
136    
137    
138    Version 0.5.1 (6 December 2007)
139    
140      * packaging changes:
141        - added autoconf checks for pthread library
142        - added autoconf check for pthread bug found on certain NPTL-enabled
143          glibc versions (see Gentoo bug report #194076)
144        - added autoconf checks for MS Windows
145    
146      * general changes:
147        - bugfix: the thread used by an editor plugin didn't die when the
148          editor closed
149        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
150          out all the space. operator--() did not apply size_mask after
151          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
152          order to avoid problems with the _NonVolatileReader functions.
153        - bugfix: Stream.h: added a missing divide by BytesPerSample in
154          GetWriteSpace(). Since this function is currently only used in
155          the stream's qsort() compare function, it didn't trigger any
156          bugs.
157        - Resampler.h, Synthesizer.h: cubic interpolation now works in
158          24bit mode too. Faster method to read 24bit words on little
159          endian machines (x86): replaced 3 byte reads + shifts with a 1
160          unaligned 32bit read and shift
161        - experimental support for MS Windows (MIDI input via MME, AUDIO
162          output via ASIO)
163        - made handling of SIGINT signal (Ctrl-C) a bit more robust
164        - support for monitoring the total number of active disk streams
165          (new LSCP commands: GET TOTAL_STREAM_COUNT,
166          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
167    
168      * AUDIO driver:
169        - added Windows ASIO low latency audio driver
170    
171      * MIDI driver:
172        - added MME Windows MIDI driver
173    
174      * LSCP server:
175        - added support for Windows style path / filenames, however with
176          forward slash path separators instead of backslash
177          (i.e. "C:/foo/bar.gig")
178        - allow naughty liblscp to send non-string device parameters within
179          apostrophes as well
180        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
181          "LIST FILE INSTRUMENTS <file>" and
182          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
183          about an arbitrary instrument file on the system where the sampler is
184          running on
185    
186    Version 0.5.0 (15 October 2007)
187    
188      * packaging changes:
189        - config.h is not going to be installed along with liblinuxsampler's
190          API header files anymore
191        - only the API relevant header (and source) files will be exported to
192          the Doxygen API documentation (explicitly listed in Doxyfile.in)
193        - added completely new XCode project files for Mac OSX which is now
194          capable to execute our autoconf environment, thus no need anymore
195          to maintain the compile time configuration file (osx/version.h) for
196          OSX manually (patch by Toshi Nagata)
197        - fixed buggy boolean --enable-foo / --disable-foo configure script
198          parameters
199        - global.h now only covers global definitions that are needed for the
200          C++ API header files, all implementation internal global definitions
201          are now in global_private.h
202        - atomic.h is not exposed to the C++ API anymore
203        - no need to include config.h anymore for using LS's API header files
204        - fixed warnings in API doc generation
205    
206      * general changes:
207        - replaced the old, confusing MIDI program change mechanism by a
208          flexible MIDI instrument mapper which allows to map arbitrary
209          (MIDI bank, MIDI program) pairs with arbitrary
210          (engine type, instrument file, file index) triplets which will be
211          loaded on the respective channel when such MIDI program change
212          messages arrive, beside that, each entry allows to define a life-time
213          strategy for the instrument, so the user can define whether the
214          instrument should i.e. be permanently loaded (to be able to switch
215          quickly among sounds) or i.e. loaded just on demand when the
216          respective program change arrives (to safe RAM space), as well as a
217          global volume factor for each entry, so the user can adjust the volume
218          dynamic of his mapped instrument collection without having to modify
219          the instrument files, also one can manage arbitrary amount of such
220          MIDI instrument maps and assign each sampler channel individually
221          a certain map, so that i.e. separation of normal instruments and
222          drumkits is possible
223        - new notification events for tracking changes to audio/MIDI devices,
224          MIDI instrument maps, MIDI instruments, FX sends, global volume.
225        - sampler was limited to load max. 200 instruments in the background
226          due to a constant size RingBuffer FIFO which is now replaced by a
227          dynamic (unlimited) size std::list FIFO
228        - added FX sends, these allow to route audio signals to arbitrary audio
229          output channels for being processed by external effect processors
230          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
231          controllers
232        - global (sampler wide) volume can now be controlled at runtime
233        - Implemented new, improved notification system
234        - fixed compilation errors regarding OSX
235          (patch by Toshi Nagata)
236        - implemented instruments database
237        - added support for escape sequences to the instruments database
238        - added highly experimental support for on-the-fly instrument editing
239          within the sampler's process (by using instrument editor plugins),
240          you'll notice the new "Registered instrument editors:" message on
241          startup, added a new LSCP command:
242          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
243          to spawn a matching instrument editor for the instrument on the
244          given sampler channel, the plugin path can be overridden at compile
245          time with ./configure --enable-plugin-dir=/some/dir
246        - added experimental code for synchronizing instrument editors hosted
247          in the sampler's process to safely edit instruments while playing
248          without a crash (hopefully) by either suspending single regions
249          wherever possible or if unavoidable whole engine(s)
250        - fixed several issues in fundamental "Thread" class: set scheduling
251          policy and priority on thread level, set a minimum stack size for
252          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
253          threads simply inherited properties of starting thread instead of
254          setting their own policy and priority
255        - minor fix in our automatic stack trace mechanism on crashes, the
256          main process did not wait for the stack trace process to finish
257          its output
258        - fixed some minor memory leaks
259        - reenabled assembly features support, at the moment only for
260          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
261        - minor assembly fix in x86 features detection (don't use the PIC
262          register, to avoid relocations in the text segment at runtime)
263        - POSIX callback functions of Thread.h are hidden
264    
265      * MIDI driver:
266        - dispatch bank select (MSB and LSB) messages
267    
268      * audio driver:
269        - the ALSA audio output driver parameters now reflect the correct
270          parameter value ranges for the respective selected sound card
271          (patch by Till Wimmer, a bit fixed and extended)
272    
273      * Gigasampler format engine:
274        - if a filter is used and EG2 finishes before EG1, let the voice
275          die when EG2 has finished (this fixes a problem with clicks and
276          voice starvation for some gigs)
277        - playback is no longer disabled during instrument loading
278        - all notes playing on a channel that changes its instrument keep
279          playing with the old instrument until they get a note off
280          command
281        - EG fix: a release value of zero could cause noises or crash
282        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
283        - EG fine tuning: when attack is zero the EG starts at a level
284          above max sustain level, which means that there is a decay phase
285          even if sustain is 100%
286        - more EG fixes: the level could sometimes go below zero and cause
287          noises or crashes
288        - minor fix of EGDecay (patch by Toshi Nagata)
289        - fixed compiler error when --enable-override-filter-type was
290          supplied to the configure script (fixes #46)
291        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
292          instead of a fix value
293        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
294          127 (solo mode) only kill voices if the respective mode really
295          changed
296    
297      * LSCP server:
298        - fixed compile time error for old Bison versions
299          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
300        - parser now supports extended ASCII character set
301          (up to ASCII code 255, i.e. includes now umlauts and accents)
302        - filename arguments in LSCP commands now allow to use escape
303          sequences, that is directly literal as one of: \', \", \\, \n, \r,
304          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
305          code value like \xf2) (fixes bug #24)
306        - the following LSCP commands now also support escape sequences for at
307          least one of their text-based parameters (i.e. name, description):
308          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
309          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
310          "SET DB_INSTRUMENT_DIRECTORY NAME",
311          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
312          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
313          "FIND DB_INSTRUMENT_DIRECTORIES"
314        - returns verbose syntax errors (line and column where syntax error
315          occured, the unexpected character and the actually expected, possible
316          character(s), the latter only if less than 5 possibilities)
317        - made sure that LSCP syntax is not affected by gigedit locale
318          settings
319        - bugfix regarding strings parameter lists: all comma separated lists
320          of strings were treated as being one string containing commas
321          (fixes #57)
322    
323      * Bug fixes:
324        - fixed crash occurring on certain LSCP scripts (Bug 39)
325        - another thread safety fix for lscp "load engine" and "set
326          channel audio output device"
327        - fixed a crash which occurs when reassigning the same engine
328          on a sampler channel with connected MIDI device
329        - fixed a crash which occurs when changing the number of ports of a MIDI
330          device connected to a sampler channel to number less then or equal
331          to the index of the port to which the sampler channel is connected.
332        - The previous bindings were not been disconnected when altering
333          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
334          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
335        - The active stream/voice count statistic was incorrect.
336        - notification events were not been sent for some sampler
337          channel changes
338        - added default min and max values to restrict the number of allowed
339          audio output channels and MIDI input ports
340        - the connection to the PCM interface is now closed when destroying
341          an audio output device
342        - files with slash in their path or filename could not be loaded
343    
344      * test cases:
345        - updated and fixed (haven't been touched in a while)
346
