2    
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    
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    
45      * audio driver:
46        - removed the nonsense audio channel constraint (which was hard coded to
47          max. 100 audio channels) for most audio drivers
48        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
49          opposed to the LSCP specs
50        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
51          reflected the wrong value
52        - fixed a memory management bug in ASIO driver
53        - Makefile fix: JACK_CFLAGS wasn't used
54        - JACK: use jack_client_open instead of the deprecated
55          jack_client_new
56        - added (experimental) CoreAudio driver
57    
58      * MIDI driver:
59        - added JACK MIDI driver
60        - dispatch bank select as ordinary CC as well, the user might seriously
61          want to (mis)use it for some purpose ("fixed" in all current MIDI
62          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
63    
64      * instruments database:
65        - avoid time consuming samples scanning when adding instruments
66          to the instruments database
67        - added support for handling lost files in the instruments database
68        - Implemented option for adding instruments in separate directories
69          in the instruments database
70          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
71    
72      * Gigasampler format engine:
73        - fixed a memory leak that could happen when a channel was deleted
74          while notes were playing
75        - made it possible to load an instrument even if the audio thread
76          isn't running
77        - added partial support for the "Controller Triggered" MIDI rule,
78          enough for piano gigs with pedal noise samples
79        - minor fix: only mark FX sends as being modified if really the
80          respective FX send MIDI controller was used
81        - added support for GM global device volume SysEx message
82          (can be selected at compile time to either apply globally to the
83          whole sampler [default] or only to the sampler channels that are
84          connected to the respective MIDI input port the SysEx message arrived
85          on)
86        - bugfix: notes triggered at position 0 in the audio buffer were
87          sometimes wrongly killed in the same buffer, causing no sound to
88          be played
89        - added support for chromatic / drumkit mode Roland GS Sysex message
90          which is usally used to switch a part between chromatic sounds and
91          drumkit sounds (as opposed to their common default setting of MIDI
92          part 10 being a drumkit part and all other ones chromatic parts), in
93          LS however one can switch between the first 16 MIDI instrument maps
94          defined for the sampler
95        - made it possible to create multiple sample channels even if the
96          audio thread isn't running
97        - fixed crash when removing channel with active voices (#116)
98        - bugfix: on sample reference changes (instrument editor), only
99          un-cache the respective sample if it's really not used by any
100          sampler engine anymore
101        - re-cache samples in case they were changed by an instrument editor,
102          e.g. when a sample was added while playing (#82)
103        - fixed hanging notes which occured when note-off event had the exact
104          same time stamp as the voice's note-on event and occured both in the
105          same audio fragment cycle (fixes bug #112)
106    
107      * LSCP server:
108        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
109          react on MIDI data arriving on certain sampler channels (so far only
110          Note-On and Note-Off events are sent via this LSCP event)
111        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
112          react on MIDI data arriving on certain MIDI input devices (so far only
113          Note-On and Note-Off events are sent via this LSCP event)
114        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
115          SET DB_INSTRUMENT FILE_PATH
116        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
117          frontends to send MIDI messages to specific sampler channel
118        - added two additional fields to GET FILE INSTRUMENT INFO command -
119          KEY_BINDINGS and KEYSWITCH_BINDINGS
120        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
121          was incorrect
122        - Optimized the retrieval of the MIDI instrument mappings
123        - added new LSCP command "SET VOICES" to globally alter the maximum
124          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
125          be triggered respectively
126        - added new LSCP command "SET STREAMS" to globally alter the maximum
127          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
128          which will be triggered respectively
129        - bugfix: retry if "select" returns EINTR (this fixes a crash when
130          a gigedit file dialog is opened)
131        - close all connections when LSCPServer is deleted
132    
133      * Bug fixes:
134        - fixed a crash which occurs when removing a sampler channel waiting
135          to start instrument loading after another channel
136        - fixed a crash which occurs when removing a sampler channel with
137          instrument loading in progress (bug #113)
138        - fixed termination caused by uncaught exception when adding MIDI
139          instrument with PERSISTENT load mode
140        - fixed possible iterator invalidations when resetting the sampler
141        - fixed memory leaks when issuing the following LSCP commands:
142          GET AUDIO_OUTPUT_DRIVER INFO
143          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
144          GET MIDI_INPUT_DRIVER INFO
145          GET MIDI_INPUT_DRIVER_PARAMETER INFO
146        - fixed possible compilation error when sqlite is not present
147        - fixed orphaned pointers when setting maximum voices limit (bug #118)
148        - fixed crash when changing the audio output device of a sampler
149          channel with loaded instrument and start playing notes
150        - fixed endless loop in Engine::SuspendAll() (bug #120)
151    
152    
153    Version 0.5.1 (6 December 2007)
154    
155      * packaging changes:
156        - added autoconf checks for pthread library
157        - added autoconf check for pthread bug found on certain NPTL-enabled
158          glibc versions (see Gentoo bug report #194076)
159        - added autoconf checks for MS Windows
160    
161      * general changes:
162        - bugfix: the thread used by an editor plugin didn't die when the
163          editor closed
164        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
165          out all the space. operator--() did not apply size_mask after
166          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
167          order to avoid problems with the _NonVolatileReader functions.
168        - bugfix: Stream.h: added a missing divide by BytesPerSample in
169          GetWriteSpace(). Since this function is currently only used in
170          the stream's qsort() compare function, it didn't trigger any
171          bugs.
172        - Resampler.h, Synthesizer.h: cubic interpolation now works in
173          24bit mode too. Faster method to read 24bit words on little
174          endian machines (x86): replaced 3 byte reads + shifts with a 1
175          unaligned 32bit read and shift
176        - experimental support for MS Windows (MIDI input via MME, AUDIO
177          output via ASIO)
178        - made handling of SIGINT signal (Ctrl-C) a bit more robust
179        - support for monitoring the total number of active disk streams
180          (new LSCP commands: GET TOTAL_STREAM_COUNT,
181          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
182    
183      * AUDIO driver:
184        - added Windows ASIO low latency audio driver
185    
186      * MIDI driver:
187        - added MME Windows MIDI driver
188    
189      * LSCP server:
190        - added support for Windows style path / filenames, however with
191          forward slash path separators instead of backslash
192          (i.e. "C:/foo/bar.gig")
193        - allow naughty liblscp to send non-string device parameters within
194          apostrophes as well
195        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
196          "LIST FILE INSTRUMENTS <file>" and
197          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
198          about an arbitrary instrument file on the system where the sampler is
199          running on
200    
201    Version 0.5.0 (15 October 2007)
202    
203      * packaging changes:
204        - config.h is not going to be installed along with liblinuxsampler's
205          API header files anymore
206        - only the API relevant header (and source) files will be exported to
207          the Doxygen API documentation (explicitly listed in Doxyfile.in)
208        - added completely new XCode project files for Mac OSX which is now
209          capable to execute our autoconf environment, thus no need anymore
210          to maintain the compile time configuration file (osx/version.h) for
211          OSX manually (patch by Toshi Nagata)
212        - fixed buggy boolean --enable-foo / --disable-foo configure script
213          parameters
214        - global.h now only covers global definitions that are needed for the
215          C++ API header files, all implementation internal global definitions
216          are now in global_private.h
217        - atomic.h is not exposed to the C++ API anymore
218        - no need to include config.h anymore for using LS's API header files
219        - fixed warnings in API doc generation
220

248        - Implemented new, improved notification system
249        - fixed compilation errors regarding OSX
250          (patch by Toshi Nagata)
251        - implemented instruments database
252        - added support for escape sequences to the instruments database
253        - added highly experimental support for on-the-fly instrument editing
254          within the sampler's process (by using instrument editor plugins),
255          you'll notice the new "Registered instrument editors:" message on
256          startup, added a new LSCP command:
257          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
258          to spawn a matching instrument editor for the instrument on the
259          given sampler channel, the plugin path can be overridden at compile
260          time with ./configure --enable-plugin-dir=/some/dir
261        - added experimental code for synchronizing instrument editors hosted
262          in the sampler's process to safely edit instruments while playing
263          without a crash (hopefully) by either suspending single regions
264          wherever possible or if unavoidable whole engine(s)
265        - fixed several issues in fundamental "Thread" class: set scheduling
266          policy and priority on thread level, set a minimum stack size for
267          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
268          threads simply inherited properties of starting thread instead of
269          setting their own policy and priority
270        - minor fix in our automatic stack trace mechanism on crashes, the
271          main process did not wait for the stack trace process to finish
272          its output
273        - fixed some minor memory leaks
274        - reenabled assembly features support, at the moment only for
275          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
276        - minor assembly fix in x86 features detection (don't use the PIC
277          register, to avoid relocations in the text segment at runtime)
278        - POSIX callback functions of Thread.h are hidden
279    
280    * MIDI driver:    * MIDI driver:
281      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
282    
283      * audio driver:
284        - the ALSA audio output driver parameters now reflect the correct
285          parameter value ranges for the respective selected sound card
286          (patch by Till Wimmer, a bit fixed and extended)
287

295        command        command
296        - EG fix: a release value of zero could cause noises or crash
297        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
298        - EG fine tuning: when attack is zero the EG starts at a level
299          above max sustain level, which means that there is a decay phase
300          even if sustain is 100%
301        - more EG fixes: the level could sometimes go below zero and cause
302          noises or crashes
303        - minor fix of EGDecay (patch by Toshi Nagata)
304        - fixed compiler error when --enable-override-filter-type was
305          supplied to the configure script (fixes #46)
306        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
307          instead of a fix value
308        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
309          127 (solo mode) only kill voices if the respective mode really
310          changed
311    
312      * LSCP server:
313        - fixed compile time error for old Bison versions
314          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
315        - parser now supports extended ASCII character set
316          (up to ASCII code 255, i.e. includes now umlauts and accents)
317        - filename arguments in LSCP commands now allow to use escape
318          sequences, that is directly literal as one of: \', \", \\, \n, \r,
319          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
320          code value like \xf2) (fixes bug #24)
321        - the following LSCP commands now also support escape sequences for at
322          least one of their text-based parameters (i.e. name, description):
323          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
324          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
325          "SET DB_INSTRUMENT_DIRECTORY NAME",
326          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
327          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
328          "FIND DB_INSTRUMENT_DIRECTORIES"
329        - returns verbose syntax errors (line and column where syntax error
330          occured, the unexpected character and the actually expected, possible
331          character(s), the latter only if less than 5 possibilities)
332        - made sure that LSCP syntax is not affected by gigedit locale
333          settings
334        - bugfix regarding strings parameter lists: all comma separated lists
335          of strings were treated as being one string containing commas
336          (fixes #57)
337    
338    * Bug fixes:    * Bug fixes:
339      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
340      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
341        channel audio output device"        channel audio output device"
342        - fixed a crash which occurs when reassigning the same engine
343          on a sampler channel with connected MIDI device
344        - fixed a crash which occurs when changing the number of ports of a MIDI
345          device connected to a sampler channel to number less then or equal
346          to the index of the port to which the sampler channel is connected.
347        - The previous bindings were not been disconnected when altering
348          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
349          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
350        - The active stream/voice count statistic was incorrect.
351        - notification events were not been sent for some sampler
352          channel changes
353        - added default min and max values to restrict the number of allowed
354          audio output channels and MIDI input ports
355        - the connection to the PCM interface is now closed when destroying
356          an audio output device
357        - files with slash in their path or filename could not be loaded
358    
359      * test cases:
360        - updated and fixed (haven't been touched in a while)
