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