2    
3      * General changes:
4        - Refactoring: moved the independent code from
5          the Gigasampler format engine to base classes
6    
7      * Gigasampler format engine:
8        - implemented the "round robin keyboard" dimension
9        - fixed round robin and random dimensions for cases when number of
10          dimension zones is not a power of two
11        - made round robin use a counter for each region instead of each
12          key
13    
14      * SFZ format engine
15        - Initial implementation (not usable yet)
16    
17      * SoundFont format engine
18        - Initial implementation (not usable yet)
19    
20      * Host plugins:
21        - AU bugfix: failed to destroy its audio/MIDI devices
22        - Listen to all interfaces on Mac OS X (INADDR_ANY)
23    
24      * MIDI driver:
25        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
26          the ALSA sequencer client name
27    
28      * LSCP server:
29        - added support for sending MIDI CC messages via LSCP command
30          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
31    
32      * Bug fixes:
33        - Fixed crash which may occur when MIDI key + transpose is out of range
34    
35    Version 1.0.0 (31 July 2009)
36    
37      * packaging changes:
38        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
39          causing e.g. the libgig test to fail when
40          "./configure --disable-jack-driver" was used
41          (patch by Alexis Ballier)
42        - fixed compilation with gcc 4.3
43        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
44        - fixed configure so it detects x86_64 (#107)
45        - fixes for building with newer MinGW versions
46        - fix for building with bison 2.4 (#111)
47        - fixed building with libgig installed in a non-standard directory
48        - minor fix in configure for mmsystem.h detection on MinGW
49        - Windows: look for editor plugins and Fantasia using base
50          directory of liblinuxsampler dll (look in the same directory and one
51          directory above)
52        - configure script fix: removed unconditional use of SSE
53        - fixed building with sqlite installed in a non-standard directory
54        - when cross-compiling, don't try to create instruments.db
55        - fix for new mingw-w64 version, which has usleep
56    
57      * general changes:
58        - bugfix: on some POSIX systems instrument editor plugins refused to
59          load as we used a non-portable Linux specific struct field
60          (fixes bug #70, patch by Ronald Baljeu)
61        - fixed endless loop which occured when loading an instrument editor
62          plugin DLL on Windows systems failed
63        - fixed memory leaks that occurred when liblinuxsampler was unloaded
64        - optimized the SynchronizedConfig class so it doesn't wait
65          unnecessarily long after an update
66        - added support for notifying instrument editors on note-on / note-off
67          events (e.g. to highlight the pressed keys on the virtual keyboard
68          of gigedit)
69        - added support for triggering notes by instrument editors (see above)
70        - be verbose on DLL load errors (on Linux)
71        - fixed di-harmonic triangle LFO implementation (this LFO implementation
72          is only used by very few systems, most pick the int math
73          implementation, which is usually faster)
74        - fixes for audio drivers with varying buffer sizes
75        - experimental support for running LinuxSampler as a DSSI, LV2 and
76          VST plugin
77        - notification events for stream/voice count statistics are now sent
78          only when there are actual changes
79        - added memory ordering constraints to improve stability on
80          multi-core and multi-cpu systems
81        - maximum voices and disk streams can now be altered at runtime
82        - fixed CPU feature detection on x86_64 (maybe fixes #108)
83        - automatic stacktrace mechanism is now turned off by default and can
84          be switched on by command line option "--stacktrace" (the automatic
85          stacktrace mechanism seems to be broken on most systems at the moment)
86        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
87          a pointer to the launched InstrumentEditor object
88        - added optional 3rd party user data parameter for following
89          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
90          InstrumentEditor::Launch(),
91          InstrumentManager::LaunchInstrumentEditor()
92        - theoretical fix: made SynchronizedConfig follow C++0x memory
93          model more strictly
94        - fixes for using large audio device buffers
95        - Windows: add the installation directory to the DLL search path
96          when loading an editor plugin (solves problems with VST and
97          gigedit on systems with other GTK versions installed)
98    
99      * audio driver:
100        - removed the nonsense audio channel constraint (which was hard coded to
101          max. 100 audio channels) for most audio drivers
102        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
103          opposed to the LSCP specs
104        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
105          reflected the wrong value
106        - fixed a memory management bug in ASIO driver
107        - Makefile fix: JACK_CFLAGS wasn't used
108        - JACK: use jack_client_open instead of the deprecated
109          jack_client_new
110        - added (experimental) CoreAudio driver
111        - applied old fixes to the ASIO driver that were included in the
112          previous binary release but accidentally never committed to CVS
113          (fixes #117)
114        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
115          win64)
116        - VST: added support for sample rate and buffer size changes
117        - VST: close editor (Fantasia) when the VST is removed
118        - VST: avoid opening Fantasia more than once for each VST instance
119        - VST: export main function as "main" on Linux too (fix for
120          energyXT)
121        - VST: changed number of output channels from one stereo to 16
122          stereo
123        - added channel routing, fxsends and midi maps to the settings
124          stored in the plugin state
125        - performance optimization of AudioChannel::MixTo() and
126          AudioChannel::CopyTo() methods using GCC vector exensions
127          (if available)
128        - ASIO fixes: avoid initializing the device twice, avoid throwing
129          exception when getting parameters from a disconnected device
130    
131      * MIDI driver:
132        - added JACK MIDI driver
133        - dispatch bank select as ordinary CC as well, the user might seriously
134          want to (mis)use it for some purpose ("fixed" in all current MIDI
135          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
136        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
137          CoreMidi or AU
138        - fixed mingw-w64 compilation error in MME driver
139        - made program change handling in MIDI thread real-time safe by
140          moving the logic to a non-RT thread
141        - fixed minor memory leak in ALSA driver
142    
143      * instruments database:
144        - avoid time consuming samples scanning when adding instruments
145          to the instruments database
146        - added support for handling lost files in the instruments database
147        - Implemented option for adding instruments in separate directories
148          in the instruments database
149          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
150        - work-around for missing fnmatch function on Windows to make
151          instrument database compilable
152        - added instrument database support on Windows
153          works with both standalone mode and VST plugin.
154          the instruments DB file is located in
155          %USERPROFILE%\.linuxsampler\instruments.db which allows different
156          databases for each windows user
157          if no DB is present it automatically creates the .linuxsampler subdir
158          and then creates an empty DB
159        - fixed recursive import, which was broken on Windows
160    
161      * Gigasampler format engine:
162        - fixed a memory leak that could happen when a channel was deleted
163          while notes were playing
164        - made it possible to load an instrument even if the audio thread
165          isn't running
166        - added partial support for the "Controller Triggered" MIDI rule,
167          enough for piano gigs with pedal noise samples
168        - minor fix: only mark FX sends as being modified if really the
169          respective FX send MIDI controller was used
170        - added support for GM global device volume SysEx message
171          (can be selected at compile time to either apply globally to the
172          whole sampler [default] or only to the sampler channels that are
173          connected to the respective MIDI input port the SysEx message arrived
174          on)
175        - bugfix: notes triggered at position 0 in the audio buffer were
176          sometimes wrongly killed in the same buffer, causing no sound to
177          be played
178        - added support for chromatic / drumkit mode Roland GS Sysex message
179          which is usally used to switch a part between chromatic sounds and
180          drumkit sounds (as opposed to their common default setting of MIDI
181          part 10 being a drumkit part and all other ones chromatic parts), in
182          LS however one can switch between the first 16 MIDI instrument maps
183          defined for the sampler
184        - made it possible to create multiple sample channels even if the
185          audio thread isn't running
186        - fixed crash when removing channel with active voices (#116)
187        - bugfix: on sample reference changes (instrument editor), only
188          un-cache the respective sample if it's really not used by any
189          sampler engine anymore
190        - re-cache samples in case they were changed by an instrument editor,
191          e.g. when a sample was added while playing (#82)
192        - fixed hanging notes which occured when note-off event had the exact
193          same time stamp as the voice's note-on event and occured both in the
194          same audio fragment cycle (fixes bug #112)
195        - added support for the "fine tune" and "pitch bend range"
196          instrument-level gig parameters
197        - fixed minor artifacts in pitch bend handling
198        - added support for GS Reset SysEx message
199        - allow gig files to use unlimited downward pitch shifting
200        - added a limit check for upward pitch shifting
201        - bugfix: sometimes, when playing a note twice fast, the second
202          note was silent
203        - fixed crash happening when a pitch bend event arrived at the
204          same time a new instrument was loading
205    
206      * LSCP server:
207        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
208          react on MIDI data arriving on certain sampler channels (so far only
209          Note-On and Note-Off events are sent via this LSCP event)
210        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
211          react on MIDI data arriving on certain MIDI input devices (so far only
212          Note-On and Note-Off events are sent via this LSCP event)
213        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
214          SET DB_INSTRUMENT FILE_PATH
215        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
216          frontends to send MIDI messages to specific sampler channel
217        - added two additional fields to GET FILE INSTRUMENT INFO command -
218          KEY_BINDINGS and KEYSWITCH_BINDINGS
219        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
220          was incorrect
221        - Optimized the retrieval of the MIDI instrument mappings
222        - added new LSCP command "SET VOICES" to globally alter the maximum
223          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
224          be triggered respectively
225        - added new LSCP command "SET STREAMS" to globally alter the maximum
226          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
227          which will be triggered respectively
228        - bugfix: retry if "select" returns EINTR (this fixes a crash when
229          a gigedit file dialog is opened)
230        - close all connections when LSCPServer is deleted
231        - hard close of all sockets on exit
232        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
233          driver
234    
235      * Bug fixes:
236        - fixed a crash which occurs when removing a sampler channel waiting
237          to start instrument loading after another channel
238        - fixed a crash which occurs when removing a sampler channel with
239          instrument loading in progress (bug #113)
240        - fixed termination caused by uncaught exception when adding MIDI
241          instrument with PERSISTENT load mode
242        - fixed possible iterator invalidations when resetting the sampler
243        - fixed memory leaks when issuing the following LSCP commands:
244          GET AUDIO_OUTPUT_DRIVER INFO
245          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
246          GET MIDI_INPUT_DRIVER INFO
247          GET MIDI_INPUT_DRIVER_PARAMETER INFO
248        - fixed possible compilation error when sqlite is not present
249        - fixed orphaned pointers when setting maximum voices limit (bug #118)
250        - fixed crash when changing the audio output device of a sampler
251          channel with loaded instrument and start playing notes
252        - fixed endless loop in Engine::SuspendAll() (bug #120)
253        - fixed a low-level atomic load function that was broken on 64-bit
254          PowerPC, which probably could cause crashes on that platform
255        - fixed a memory management error which could cause a crash when a
256          plugin was unloaded
257        - bugfix: two private structs had the same name, which could cause
258          problems if the linker chose the wrong constructor
259        - fixed low-level ConditionServer usage bug that caused lockups on
260          Windows
261    
262    
263    Version 0.5.1 (6 December 2007)
264    
265      * packaging changes:
266        - added autoconf checks for pthread library
267        - added autoconf check for pthread bug found on certain NPTL-enabled
268          glibc versions (see Gentoo bug report #194076)
269        - added autoconf checks for MS Windows
270    
271      * general changes:
272        - bugfix: the thread used by an editor plugin didn't die when the
273          editor closed
274        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
275          out all the space. operator--() did not apply size_mask after
276          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
277          order to avoid problems with the _NonVolatileReader functions.
278        - bugfix: Stream.h: added a missing divide by BytesPerSample in
279          GetWriteSpace(). Since this function is currently only used in
280          the stream's qsort() compare function, it didn't trigger any
281          bugs.
282        - Resampler.h, Synthesizer.h: cubic interpolation now works in
283          24bit mode too. Faster method to read 24bit words on little
284          endian machines (x86): replaced 3 byte reads + shifts with a 1
285          unaligned 32bit read and shift
286        - experimental support for MS Windows (MIDI input via MME, AUDIO
287          output via ASIO)
288        - made handling of SIGINT signal (Ctrl-C) a bit more robust
289        - support for monitoring the total number of active disk streams
290          (new LSCP commands: GET TOTAL_STREAM_COUNT,
291          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
292    
293      * AUDIO driver:
294        - added Windows ASIO low latency audio driver
295    
296      * MIDI driver:
297        - added MME Windows MIDI driver
298    
299      * LSCP server:
300        - added support for Windows style path / filenames, however with
301          forward slash path separators instead of backslash
302          (i.e. "C:/foo/bar.gig")
303        - allow naughty liblscp to send non-string device parameters within
304          apostrophes as well
305        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
306          "LIST FILE INSTRUMENTS <file>" and
307          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
308          about an arbitrary instrument file on the system where the sampler is
309          running on
