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