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        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
45          a pointer to the launched InstrumentEditor object
46        - added optional 3rd party user data parameter for following
47          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
48          InstrumentEditor::Launch(),
49          InstrumentManager::LaunchInstrumentEditor()
50    
51      * audio driver:
52        - removed the nonsense audio channel constraint (which was hard coded to
53          max. 100 audio channels) for most audio drivers
54        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
55          opposed to the LSCP specs
56        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
57          reflected the wrong value
58        - fixed a memory management bug in ASIO driver
59        - Makefile fix: JACK_CFLAGS wasn't used
60        - JACK: use jack_client_open instead of the deprecated
61          jack_client_new
62        - added (experimental) CoreAudio driver
63    
64      * MIDI driver:
65        - added JACK MIDI driver
66        - dispatch bank select as ordinary CC as well, the user might seriously
67          want to (mis)use it for some purpose ("fixed" in all current MIDI
68          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
69    
70      * instruments database:
71        - avoid time consuming samples scanning when adding instruments
72          to the instruments database
73        - added support for handling lost files in the instruments database
74        - Implemented option for adding instruments in separate directories
75          in the instruments database
76          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
77    
78      * Gigasampler format engine:
79        - fixed a memory leak that could happen when a channel was deleted
80          while notes were playing
81        - made it possible to load an instrument even if the audio thread
82          isn't running
83        - added partial support for the "Controller Triggered" MIDI rule,
84          enough for piano gigs with pedal noise samples
85        - minor fix: only mark FX sends as being modified if really the
86          respective FX send MIDI controller was used
87        - added support for GM global device volume SysEx message
88          (can be selected at compile time to either apply globally to the
89          whole sampler [default] or only to the sampler channels that are
90          connected to the respective MIDI input port the SysEx message arrived
91          on)
92        - bugfix: notes triggered at position 0 in the audio buffer were
93          sometimes wrongly killed in the same buffer, causing no sound to
94          be played
95        - added support for chromatic / drumkit mode Roland GS Sysex message
96          which is usally used to switch a part between chromatic sounds and
97          drumkit sounds (as opposed to their common default setting of MIDI
98          part 10 being a drumkit part and all other ones chromatic parts), in
99          LS however one can switch between the first 16 MIDI instrument maps
100          defined for the sampler
101        - made it possible to create multiple sample channels even if the
102          audio thread isn't running
103        - fixed crash when removing channel with active voices (#116)
104        - bugfix: on sample reference changes (instrument editor), only
105          un-cache the respective sample if it's really not used by any
106          sampler engine anymore
107        - re-cache samples in case they were changed by an instrument editor,
108          e.g. when a sample was added while playing (#82)
109        - fixed hanging notes which occured when note-off event had the exact
110          same time stamp as the voice's note-on event and occured both in the
111          same audio fragment cycle (fixes bug #112)
112        - added support for the "fine tune" and "pitch bend range"
113          instrument-level gig parameters
114        - fixed minor artifacts in pitch bend handling
115        - added support for GS Reset SysEx message
116        - allow gig files to use unlimited downward pitch shifting
117        - added a limit check for upward pitch shifting
118    
119      * LSCP server:
120        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
121          react on MIDI data arriving on certain sampler channels (so far only
122          Note-On and Note-Off events are sent via this LSCP event)
123        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
124          react on MIDI data arriving on certain MIDI input devices (so far only
125          Note-On and Note-Off events are sent via this LSCP event)
126        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
127          SET DB_INSTRUMENT FILE_PATH
128        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
129          frontends to send MIDI messages to specific sampler channel
130        - added two additional fields to GET FILE INSTRUMENT INFO command -
131          KEY_BINDINGS and KEYSWITCH_BINDINGS
132        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
133          was incorrect
134        - Optimized the retrieval of the MIDI instrument mappings
135        - added new LSCP command "SET VOICES" to globally alter the maximum
136          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
137          be triggered respectively
138        - added new LSCP command "SET STREAMS" to globally alter the maximum
139          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
140          which will be triggered respectively
141        - bugfix: retry if "select" returns EINTR (this fixes a crash when
142          a gigedit file dialog is opened)
143        - close all connections when LSCPServer is deleted
144    
145      * Bug fixes:
146        - fixed a crash which occurs when removing a sampler channel waiting
147          to start instrument loading after another channel
148        - fixed a crash which occurs when removing a sampler channel with
149          instrument loading in progress (bug #113)
150        - fixed termination caused by uncaught exception when adding MIDI
151          instrument with PERSISTENT load mode
152        - fixed possible iterator invalidations when resetting the sampler
153        - fixed memory leaks when issuing the following LSCP commands:
154          GET AUDIO_OUTPUT_DRIVER INFO
155          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
156          GET MIDI_INPUT_DRIVER INFO
157          GET MIDI_INPUT_DRIVER_PARAMETER INFO
158        - fixed possible compilation error when sqlite is not present
159        - fixed orphaned pointers when setting maximum voices limit (bug #118)
160        - fixed crash when changing the audio output device of a sampler
161          channel with loaded instrument and start playing notes
162        - fixed endless loop in Engine::SuspendAll() (bug #120)
163        - fixed a low-level atomic load function that was broken on 64-bit
164          PowerPC, which probably could cause crashes on that platform
165    
166    
167    Version 0.5.1 (6 December 2007)
168    
169      * packaging changes:
170        - added autoconf checks for pthread library
171        - added autoconf check for pthread bug found on certain NPTL-enabled
172          glibc versions (see Gentoo bug report #194076)
173        - added autoconf checks for MS Windows
174    
175      * general changes:
176        - bugfix: the thread used by an editor plugin didn't die when the
177          editor closed
178        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
179          out all the space. operator--() did not apply size_mask after
180          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
181          order to avoid problems with the _NonVolatileReader functions.
182        - bugfix: Stream.h: added a missing divide by BytesPerSample in
183          GetWriteSpace(). Since this function is currently only used in
184          the stream's qsort() compare function, it didn't trigger any
185          bugs.
186        - Resampler.h, Synthesizer.h: cubic interpolation now works in
187          24bit mode too. Faster method to read 24bit words on little
188          endian machines (x86): replaced 3 byte reads + shifts with a 1
189          unaligned 32bit read and shift
190        - experimental support for MS Windows (MIDI input via MME, AUDIO
191          output via ASIO)
192        - made handling of SIGINT signal (Ctrl-C) a bit more robust
193        - support for monitoring the total number of active disk streams
194          (new LSCP commands: GET TOTAL_STREAM_COUNT,
195          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
196    
197      * AUDIO driver:
198        - added Windows ASIO low latency audio driver
199    
200      * MIDI driver:
201        - added MME Windows MIDI driver
202    
203      * LSCP server:
204        - added support for Windows style path / filenames, however with
205          forward slash path separators instead of backslash
206          (i.e. "C:/foo/bar.gig")
207        - allow naughty liblscp to send non-string device parameters within
208          apostrophes as well
209        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
210          "LIST FILE INSTRUMENTS <file>" and
211          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
212          about an arbitrary instrument file on the system where the sampler is
213          running on
214    
215    Version 0.5.0 (15 October 2007)
216    
217      * packaging changes:
218        - config.h is not going to be installed along with liblinuxsampler's
219          API header files anymore
220        - only the API relevant header (and source) files will be exported to
221          the Doxygen API documentation (explicitly listed in Doxyfile.in)
222        - added completely new XCode project files for Mac OSX which is now
223          capable to execute our autoconf environment, thus no need anymore
224          to maintain the compile time configuration file (osx/version.h) for
225          OSX manually (patch by Toshi Nagata)
226        - fixed buggy boolean --enable-foo / --disable-foo configure script
227          parameters
228        - global.h now only covers global definitions that are needed for the
229          C++ API header files, all implementation internal global definitions
230          are now in global_private.h
231        - atomic.h is not exposed to the C++ API anymore
232        - no need to include config.h anymore for using LS's API header files
233        - fixed warnings in API doc generation
234    
235    * general changes:    * general changes:

249          MIDI instrument maps and assign each sampler channel individually
250          a certain map, so that i.e. separation of normal instruments and
251          drumkits is possible
252        - new notification events for tracking changes to audio/MIDI devices,
253          MIDI instrument maps, MIDI instruments, FX sends, global volume.
254        - sampler was limited to load max. 200 instruments in the background
255          due to a constant size RingBuffer FIFO which is now replaced by a
256          dynamic (unlimited) size std::list FIFO
257        - added FX sends, these allow to route audio signals to arbitrary audio
258          output channels for being processed by external effect processors
259          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
260          controllers
261        - global (sampler wide) volume can now be controlled at runtime
262        - Implemented new, improved notification system
263        - fixed compilation errors regarding OSX
264          (patch by Toshi Nagata)
265        - implemented instruments database
266        - added support for escape sequences to the instruments database
267        - added highly experimental support for on-the-fly instrument editing
268          within the sampler's process (by using instrument editor plugins),
269          you'll notice the new "Registered instrument editors:" message on
270          startup, added a new LSCP command:
271          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
272          to spawn a matching instrument editor for the instrument on the
273          given sampler channel, the plugin path can be overridden at compile
274          time with ./configure --enable-plugin-dir=/some/dir
275        - added experimental code for synchronizing instrument editors hosted
276          in the sampler's process to safely edit instruments while playing
277          without a crash (hopefully) by either suspending single regions
278          wherever possible or if unavoidable whole engine(s)
279        - fixed several issues in fundamental "Thread" class: set scheduling
280          policy and priority on thread level, set a minimum stack size for
281          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
282          threads simply inherited properties of starting thread instead of
283          setting their own policy and priority
284        - minor fix in our automatic stack trace mechanism on crashes, the
285          main process did not wait for the stack trace process to finish
286          its output
287        - fixed some minor memory leaks
288        - reenabled assembly features support, at the moment only for
289          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
290        - minor assembly fix in x86 features detection (don't use the PIC
291          register, to avoid relocations in the text segment at runtime)
292        - POSIX callback functions of Thread.h are hidden
293    
294    * MIDI driver:    * MIDI driver:
295      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
296    
297      * audio driver:
298        - the ALSA audio output driver parameters now reflect the correct
299          parameter value ranges for the respective selected sound card
300          (patch by Till Wimmer, a bit fixed and extended)
301    
302    * Gigasampler format engine:    * Gigasampler format engine:
303      - if a filter is used and EG2 finishes before EG1, let the voice      - if a filter is used and EG2 finishes before EG1, let the voice
304        die when EG2 has finished (this fixes a problem with clicks and        die when EG2 has finished (this fixes a problem with clicks and
305        voice starvation for some gigs)        voice starvation for some gigs)
306        - playback is no longer disabled during instrument loading
307        - all notes playing on a channel that changes its instrument keep
308          playing with the old instrument until they get a note off
309          command
310        - EG fix: a release value of zero could cause noises or crash
311        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
312        - EG fine tuning: when attack is zero the EG starts at a level
313          above max sustain level, which means that there is a decay phase
314          even if sustain is 100%
315        - more EG fixes: the level could sometimes go below zero and cause
316          noises or crashes
317        - minor fix of EGDecay (patch by Toshi Nagata)
318        - fixed compiler error when --enable-override-filter-type was
319          supplied to the configure script (fixes #46)
320        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
321          instead of a fix value
322        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
323          127 (solo mode) only kill voices if the respective mode really
324          changed
325    
326      * LSCP server:
327        - fixed compile time error for old Bison versions
328          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
329        - parser now supports extended ASCII character set
330          (up to ASCII code 255, i.e. includes now umlauts and accents)
331        - filename arguments in LSCP commands now allow to use escape
332          sequences, that is directly literal as one of: \', \", \\, \n, \r,
333          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
334          code value like \xf2) (fixes bug #24)
335        - the following LSCP commands now also support escape sequences for at
336          least one of their text-based parameters (i.e. name, description):
337          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
338          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
339          "SET DB_INSTRUMENT_DIRECTORY NAME",
340          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
341          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
342          "FIND DB_INSTRUMENT_DIRECTORIES"
343        - returns verbose syntax errors (line and column where syntax error
344          occured, the unexpected character and the actually expected, possible
345          character(s), the latter only if less than 5 possibilities)
346        - made sure that LSCP syntax is not affected by gigedit locale
347          settings
348        - bugfix regarding strings parameter lists: all comma separated lists
349          of strings were treated as being one string containing commas
350          (fixes #57)
351    
352    * Bug fixes:    * Bug fixes:
353      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
354        - another thread safety fix for lscp "load engine" and "set
355          channel audio output device"
356        - fixed a crash which occurs when reassigning the same engine
357          on a sampler channel with connected MIDI device
358        - fixed a crash which occurs when changing the number of ports of a MIDI
359          device connected to a sampler channel to number less then or equal
360          to the index of the port to which the sampler channel is connected.
361        - The previous bindings were not been disconnected when altering
362          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
363          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
364        - The active stream/voice count statistic was incorrect.
365        - notification events were not been sent for some sampler
366          channel changes
367        - added default min and max values to restrict the number of allowed
368          audio output channels and MIDI input ports
369        - the connection to the PCM interface is now closed when destroying
370          an audio output device
371        - files with slash in their path or filename could not be loaded
372    
373      * test cases:
374        - updated and fixed (haven't been touched in a while)
375
