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