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