1  Version CVS HEAD (?)  Version CVS HEAD (?)
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        - minor fix in configure for mmsystem.h detection on MinGW
15        - Windows: look for editor plugins and Fantasia using base
16          directory of liblinuxsampler dll (look in the same directory and one
17          directory above)
18        - configure script fix: removed unconditional use of SSE
19        - fixed building with sqlite installed in a non-standard directory
20    
21      * general changes:
22        - bugfix: on some POSIX systems instrument editor plugins refused to
23          load as we used a non-portable Linux specific struct field
24          (fixes bug #70, patch by Ronald Baljeu)
25        - fixed endless loop which occured when loading an instrument editor
26          plugin DLL on Windows systems failed
27        - fixed memory leaks that occurred when liblinuxsampler was unloaded
28        - optimized the SynchronizedConfig class so it doesn't wait
29          unnecessarily long after an update
30        - added support for notifying instrument editors on note-on / note-off
31          events (e.g. to highlight the pressed keys on the virtual keyboard
32          of gigedit)
33        - added support for triggering notes by instrument editors (see above)
34        - be verbose on DLL load errors (on Linux)
35        - fixed di-harmonic triangle LFO implementation (this LFO implementation
36          is only used by very few systems, most pick the int math
37          implementation, which is usually faster)
38        - fixes for audio drivers with varying buffer sizes
39        - experimental support for running LinuxSampler as a DSSI, LV2 and
40          VST plugin
41        - notification events for stream/voice count statistics are now sent
42          only when there are actual changes
43        - added memory ordering constraints to improve stability on
44          multi-core and multi-cpu systems
45        - maximum voices and disk streams can now be altered at runtime
46        - fixed CPU feature detection on x86_64 (maybe fixes #108)
47        - automatic stacktrace mechanism is now turned off by default and can
48          be switched on by command line option "--stacktrace" (the automatic
49          stacktrace mechanism seems to be broken on most systems at the moment)
50        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
51          a pointer to the launched InstrumentEditor object
52        - added optional 3rd party user data parameter for following
53          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
54          InstrumentEditor::Launch(),
55          InstrumentManager::LaunchInstrumentEditor()
56        - theoretical fix: made SynchronizedConfig follow C++0x memory
57          model more strictly
58        - fixes for using large audio device buffers
59    
60      * audio driver:
61        - removed the nonsense audio channel constraint (which was hard coded to
62          max. 100 audio channels) for most audio drivers
63        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
64          opposed to the LSCP specs
65        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
66          reflected the wrong value
67        - fixed a memory management bug in ASIO driver
68        - Makefile fix: JACK_CFLAGS wasn't used
69        - JACK: use jack_client_open instead of the deprecated
70          jack_client_new
71        - added (experimental) CoreAudio driver
72        - applied old fixes to the ASIO driver that were included in the
73          previous binary release but accidentally never committed to CVS
74          (fixes #117)
75        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
76          win64)
77        - VST: added support for sample rate and buffer size changes
78        - VST: close editor (Fantasia) when the VST is removed
79        - VST: avoid opening Fantasia more than once for each VST instance
80        - VST: export main function as "main" on Linux too (fix for
81          energyXT)
82        - VST: changed number of output channels from one stereo to 16
83          stereo
84        - added channel routing, fxsends and midi maps to the settings
85          stored in the plugin state
86        - performance optimization of AudioChannel::MixTo() and
87          AudioChannel::CopyTo() methods using GCC vector exensions
88          (if available)
89    
90      * MIDI driver:
91        - added JACK MIDI driver
92        - dispatch bank select as ordinary CC as well, the user might seriously
93          want to (mis)use it for some purpose ("fixed" in all current MIDI
94          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
95        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
96          CoreMidi or AU
97        - fixed mingw-w64 compilation error in MME driver
98        - made program change handling in MIDI thread real-time safe by
99          moving the logic to a non-RT thread
100    
101      * instruments database:
102        - avoid time consuming samples scanning when adding instruments
103          to the instruments database
104        - added support for handling lost files in the instruments database
105        - Implemented option for adding instruments in separate directories
106          in the instruments database
107          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
108        - work-around for missing fnmatch function on Windows to make
109          instrument database compilable
110        - added instrument database support on Windows
111          works with both standalone mode and VST plugin.
112          the instruments DB file is located in
113          %USERPROFILE%\.linuxsampler\instruments.db which allows different
114          databases for each windows user
115          if no DB is present it automatically creates the .linuxsampler subdir
116          and then creates an empty DB
117    
118      * Gigasampler format engine:
119        - fixed a memory leak that could happen when a channel was deleted
120          while notes were playing
121        - made it possible to load an instrument even if the audio thread
122          isn't running
123        - added partial support for the "Controller Triggered" MIDI rule,
124          enough for piano gigs with pedal noise samples
125        - minor fix: only mark FX sends as being modified if really the
126          respective FX send MIDI controller was used
127        - added support for GM global device volume SysEx message
128          (can be selected at compile time to either apply globally to the
129          whole sampler [default] or only to the sampler channels that are
130          connected to the respective MIDI input port the SysEx message arrived
131          on)
132        - bugfix: notes triggered at position 0 in the audio buffer were
133          sometimes wrongly killed in the same buffer, causing no sound to
134          be played
135        - added support for chromatic / drumkit mode Roland GS Sysex message
136          which is usally used to switch a part between chromatic sounds and
137          drumkit sounds (as opposed to their common default setting of MIDI
138          part 10 being a drumkit part and all other ones chromatic parts), in
139          LS however one can switch between the first 16 MIDI instrument maps
140          defined for the sampler
141        - made it possible to create multiple sample channels even if the
142          audio thread isn't running
143        - fixed crash when removing channel with active voices (#116)
144        - bugfix: on sample reference changes (instrument editor), only
145          un-cache the respective sample if it's really not used by any
146          sampler engine anymore
147        - re-cache samples in case they were changed by an instrument editor,
148          e.g. when a sample was added while playing (#82)
149        - fixed hanging notes which occured when note-off event had the exact
150          same time stamp as the voice's note-on event and occured both in the
151          same audio fragment cycle (fixes bug #112)
152        - added support for the "fine tune" and "pitch bend range"
153          instrument-level gig parameters
154        - fixed minor artifacts in pitch bend handling
155        - added support for GS Reset SysEx message
156        - allow gig files to use unlimited downward pitch shifting
157        - added a limit check for upward pitch shifting
158        - bugfix: sometimes, when playing a note twice fast, the second
159          note was silent
160        - fixed crash happening when a pitch bend event arrived at the
161          same time a new instrument was loading
162    
163      * LSCP server:
164        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
165          react on MIDI data arriving on certain sampler channels (so far only
166          Note-On and Note-Off events are sent via this LSCP event)
167        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
168          react on MIDI data arriving on certain MIDI input devices (so far only
169          Note-On and Note-Off events are sent via this LSCP event)
170        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
171          SET DB_INSTRUMENT FILE_PATH
172        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
173          frontends to send MIDI messages to specific sampler channel
174        - added two additional fields to GET FILE INSTRUMENT INFO command -
175          KEY_BINDINGS and KEYSWITCH_BINDINGS
176        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
177          was incorrect
178        - Optimized the retrieval of the MIDI instrument mappings
179        - added new LSCP command "SET VOICES" to globally alter the maximum
180          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
181          be triggered respectively
182        - added new LSCP command "SET STREAMS" to globally alter the maximum
183          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
184          which will be triggered respectively
185        - bugfix: retry if "select" returns EINTR (this fixes a crash when
186          a gigedit file dialog is opened)
187        - close all connections when LSCPServer is deleted
188        - hard close of all sockets on exit
189        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
190          driver
191    
192      * Bug fixes:
193        - fixed a crash which occurs when removing a sampler channel waiting
194          to start instrument loading after another channel
195        - fixed a crash which occurs when removing a sampler channel with
196          instrument loading in progress (bug #113)
197        - fixed termination caused by uncaught exception when adding MIDI
198          instrument with PERSISTENT load mode
199        - fixed possible iterator invalidations when resetting the sampler
200        - fixed memory leaks when issuing the following LSCP commands:
201          GET AUDIO_OUTPUT_DRIVER INFO
202          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
203          GET MIDI_INPUT_DRIVER INFO
204          GET MIDI_INPUT_DRIVER_PARAMETER INFO
205        - fixed possible compilation error when sqlite is not present
206        - fixed orphaned pointers when setting maximum voices limit (bug #118)
207        - fixed crash when changing the audio output device of a sampler
208          channel with loaded instrument and start playing notes
209        - fixed endless loop in Engine::SuspendAll() (bug #120)
210        - fixed a low-level atomic load function that was broken on 64-bit
211          PowerPC, which probably could cause crashes on that platform
212        - fixed a memory management error which could cause a crash when a
213          plugin was unloaded
214        - bugfix: two private structs had the same name, which could cause
215          problems if the linker chose the wrong constructor
216    
217    
218    Version 0.5.1 (6 December 2007)
219    
220      * packaging changes:
221        - added autoconf checks for pthread library
222        - added autoconf check for pthread bug found on certain NPTL-enabled
223          glibc versions (see Gentoo bug report #194076)
224        - added autoconf checks for MS Windows
225    
226      * general changes:
227        - bugfix: the thread used by an editor plugin didn't die when the
228          editor closed
229        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
230          out all the space. operator--() did not apply size_mask after
231          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
232          order to avoid problems with the _NonVolatileReader functions.
233        - bugfix: Stream.h: added a missing divide by BytesPerSample in
234          GetWriteSpace(). Since this function is currently only used in
235          the stream's qsort() compare function, it didn't trigger any
236          bugs.
237        - Resampler.h, Synthesizer.h: cubic interpolation now works in
238          24bit mode too. Faster method to read 24bit words on little
239          endian machines (x86): replaced 3 byte reads + shifts with a 1
240          unaligned 32bit read and shift
241        - experimental support for MS Windows (MIDI input via MME, AUDIO
242          output via ASIO)
243        - made handling of SIGINT signal (Ctrl-C) a bit more robust
244        - support for monitoring the total number of active disk streams
245          (new LSCP commands: GET TOTAL_STREAM_COUNT,
246          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
247    
248      * AUDIO driver:
249        - added Windows ASIO low latency audio driver
250    
251      * MIDI driver:
252        - added MME Windows MIDI driver
253    
254      * LSCP server:
255        - added support for Windows style path / filenames, however with
256          forward slash path separators instead of backslash
257          (i.e. "C:/foo/bar.gig")
258        - allow naughty liblscp to send non-string device parameters within
259          apostrophes as well
260        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
261          "LIST FILE INSTRUMENTS <file>" and
262          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
263          about an arbitrary instrument file on the system where the sampler is
264          running on
265    
266    Version 0.5.0 (15 October 2007)
267    
268      * packaging changes:
269        - config.h is not going to be installed along with liblinuxsampler's
270          API header files anymore
271        - only the API relevant header (and source) files will be exported to
272          the Doxygen API documentation (explicitly listed in Doxyfile.in)
273        - added completely new XCode project files for Mac OSX which is now
274          capable to execute our autoconf environment, thus no need anymore
275          to maintain the compile time configuration file (osx/version.h) for
276          OSX manually (patch by Toshi Nagata)
277        - fixed buggy boolean --enable-foo / --disable-foo configure script
278          parameters
279        - global.h now only covers global definitions that are needed for the
280          C++ API header files, all implementation internal global definitions
281          are now in global_private.h
282        - atomic.h is not exposed to the C++ API anymore
283        - no need to include config.h anymore for using LS's API header files
284        - fixed warnings in API doc generation
285    
286    * general changes:    * general changes:
287      - replaced the old, confusing MIDI program change mechanism by a      - replaced the old, confusing MIDI program change mechanism by a

300          MIDI instrument maps and assign each sampler channel individually
301          a certain map, so that i.e. separation of normal instruments and
302          drumkits is possible
303        - new notification events for tracking changes to audio/MIDI devices,
304          MIDI instrument maps, MIDI instruments, FX sends, global volume.
305        - sampler was limited to load max. 200 instruments in the background
306          due to a constant size RingBuffer FIFO which is now replaced by a
307          dynamic (unlimited) size std::list FIFO
308        - added FX sends, these allow to route audio signals to arbitrary audio
309          output channels for being processed by external effect processors
310          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
311          controllers
312        - global (sampler wide) volume can now be controlled at runtime
313        - Implemented new, improved notification system
314        - fixed compilation errors regarding OSX
315          (patch by Toshi Nagata)
316        - implemented instruments database
317        - added support for escape sequences to the instruments database
318        - added highly experimental support for on-the-fly instrument editing
319          within the sampler's process (by using instrument editor plugins),
320          you'll notice the new "Registered instrument editors:" message on
321          startup, added a new LSCP command:
322          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
323          to spawn a matching instrument editor for the instrument on the
324          given sampler channel, the plugin path can be overridden at compile
325          time with ./configure --enable-plugin-dir=/some/dir
326        - added experimental code for synchronizing instrument editors hosted
327          in the sampler's process to safely edit instruments while playing
328          without a crash (hopefully) by either suspending single regions
329          wherever possible or if unavoidable whole engine(s)
330        - fixed several issues in fundamental "Thread" class: set scheduling
331          policy and priority on thread level, set a minimum stack size for
332          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
333          threads simply inherited properties of starting thread instead of
334          setting their own policy and priority
335        - minor fix in our automatic stack trace mechanism on crashes, the
336          main process did not wait for the stack trace process to finish
337          its output
338        - fixed some minor memory leaks
339        - reenabled assembly features support, at the moment only for
340          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
341        - minor assembly fix in x86 features detection (don't use the PIC
342          register, to avoid relocations in the text segment at runtime)
343        - POSIX callback functions of Thread.h are hidden
344    
345    * MIDI driver:    * MIDI driver:
346      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
347    
348      * audio driver:
349        - the ALSA audio output driver parameters now reflect the correct
350          parameter value ranges for the respective selected sound card
351          (patch by Till Wimmer, a bit fixed and extended)
352    
353    * Gigasampler format engine:    * Gigasampler format engine:
354      - 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
355        die when EG2 has finished (this fixes a problem with clicks and        die when EG2 has finished (this fixes a problem with clicks and
356        voice starvation for some gigs)        voice starvation for some gigs)
357        - playback is no longer disabled during instrument loading
358        - all notes playing on a channel that changes its instrument keep
359          playing with the old instrument until they get a note off
360          command
361        - EG fix: a release value of zero could cause noises or crash
362        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
363        - EG fine tuning: when attack is zero the EG starts at a level
364          above max sustain level, which means that there is a decay phase
365          even if sustain is 100%
366        - more EG fixes: the level could sometimes go below zero and cause
367          noises or crashes
368        - minor fix of EGDecay (patch by Toshi Nagata)
369        - fixed compiler error when --enable-override-filter-type was
370          supplied to the configure script (fixes #46)
371        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
372          instead of a fix value
373        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
374          127 (solo mode) only kill voices if the respective mode really
375          changed
376    
377      * LSCP server:
378        - fixed compile time error for old Bison versions
379          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
380        - parser now supports extended ASCII character set
381          (up to ASCII code 255, i.e. includes now umlauts and accents)
382        - filename arguments in LSCP commands now allow to use escape
383          sequences, that is directly literal as one of: \', \", \\, \n, \r,
384          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
