1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3      * General changes:
4        - Refactoring: moved the independent code from
5          the Gigasampler format engine to base classes
6        - command line option '--profile' is currently disabled, since the
7          respective profiling code is currently broken
8        - Introduced support for optional environment variable
9          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
10          where the sampler shall look for instrument editor plugins
11          (patch by Luis Garrido, slightly modified).
12    
13      * Gigasampler format engine:
14        - implemented the "round robin keyboard" dimension
15        - fixed round robin and random dimensions for cases when number of
16          dimension zones is not a power of two
17        - made round robin use a counter for each region instead of each
18          key
19    
20      * SFZ format engine:
21        - Initial implementation (not usable yet)
22        - added support for v2 multiple stage envelope generators
23        - added a fine-tuned v1 envelope generator instead of using the
24          one from the gig engine
25        - fixed memory leak and memory handling errors
26        - added support for trigger=first, trigger=legato and sw_previous
27        - allow non-numerical key values ("C#4" for example)
28        - "key" opcode now sets pitch_keycenter too
29        - fixed error when unloading instrument with same sample used by
30          multiple regions
31        - added some opcode aliases, like loopmode for loop_mode, to be
32          more compatible
33        - added support for trigger=release and rt_decay
34    
35      * SoundFont format engine:
36        - Initial implementation (not usable yet)
37    
38      * Host plugins:
39        - AU bugfix: failed to destroy its audio/MIDI devices
40        - Listen to all interfaces on Mac OS X (INADDR_ANY)
41        - VST bugfix: If the host called resume() before and after
42          changing sample rate or block size, the number of channels was
43          incorrectly set to two. This caused silence in Cubase 5.
44    
45      * MIDI driver:
46        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
47          the ALSA sequencer client name
48    
49      * LSCP server:
50        - added support for sending MIDI CC messages via LSCP command
51          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
52    
53      * Bug fixes:
54        - Fixed crash which may occur when MIDI key + transpose is out of range
55    
56    Version 1.0.0 (31 July 2009)
57    
58      * packaging changes:
59        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
60          causing e.g. the libgig test to fail when
61          "./configure --disable-jack-driver" was used
62          (patch by Alexis Ballier)
63        - fixed compilation with gcc 4.3
64        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
65        - fixed configure so it detects x86_64 (#107)
66        - fixes for building with newer MinGW versions
67        - fix for building with bison 2.4 (#111)
68        - fixed building with libgig installed in a non-standard directory
69        - minor fix in configure for mmsystem.h detection on MinGW
70        - Windows: look for editor plugins and Fantasia using base
71          directory of liblinuxsampler dll (look in the same directory and one
72          directory above)
73        - configure script fix: removed unconditional use of SSE
74        - fixed building with sqlite installed in a non-standard directory
75        - when cross-compiling, don't try to create instruments.db
76        - fix for new mingw-w64 version, which has usleep
77    
78    * general changes:    * general changes:
79      - bugfix: on some POSIX systems instrument editor plugins refused to      - bugfix: on some POSIX systems instrument editor plugins refused to
80        load as we used a non-portable Linux specific struct field        load as we used a non-portable Linux specific struct field
81        (fixes bug #70, patch by Ronald Baljeu)        (fixes bug #70, patch by Ronald Baljeu)
82        - fixed endless loop which occured when loading an instrument editor
83          plugin DLL on Windows systems failed
84        - fixed memory leaks that occurred when liblinuxsampler was unloaded
85        - optimized the SynchronizedConfig class so it doesn't wait
86          unnecessarily long after an update
87        - added support for notifying instrument editors on note-on / note-off
88          events (e.g. to highlight the pressed keys on the virtual keyboard
89          of gigedit)
90        - added support for triggering notes by instrument editors (see above)
91        - be verbose on DLL load errors (on Linux)
92        - fixed di-harmonic triangle LFO implementation (this LFO implementation
93          is only used by very few systems, most pick the int math
94          implementation, which is usually faster)
95        - fixes for audio drivers with varying buffer sizes
96        - experimental support for running LinuxSampler as a DSSI, LV2 and
97          VST plugin
98        - notification events for stream/voice count statistics are now sent
99          only when there are actual changes
100        - added memory ordering constraints to improve stability on
101          multi-core and multi-cpu systems
102        - maximum voices and disk streams can now be altered at runtime
103        - fixed CPU feature detection on x86_64 (maybe fixes #108)
104        - automatic stacktrace mechanism is now turned off by default and can
105          be switched on by command line option "--stacktrace" (the automatic
106          stacktrace mechanism seems to be broken on most systems at the moment)
107        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
108          a pointer to the launched InstrumentEditor object
109        - added optional 3rd party user data parameter for following
110          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
111          InstrumentEditor::Launch(),
112          InstrumentManager::LaunchInstrumentEditor()
113        - theoretical fix: made SynchronizedConfig follow C++0x memory
114          model more strictly
115        - fixes for using large audio device buffers
116        - Windows: add the installation directory to the DLL search path
117          when loading an editor plugin (solves problems with VST and
118          gigedit on systems with other GTK versions installed)
119    
120    * audio driver:    * audio driver:
121      - removed the nonsense audio channel constraint (which was hard coded to      - removed the nonsense audio channel constraint (which was hard coded to
122        max. 100 audio channels) for most audio drivers        max. 100 audio channels) for most audio drivers
123        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
124          opposed to the LSCP specs
125        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
126          reflected the wrong value
127        - fixed a memory management bug in ASIO driver
128        - Makefile fix: JACK_CFLAGS wasn't used
129        - JACK: use jack_client_open instead of the deprecated
130          jack_client_new
131        - added (experimental) CoreAudio driver
132        - applied old fixes to the ASIO driver that were included in the
133          previous binary release but accidentally never committed to CVS
134          (fixes #117)
135        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
136          win64)
137        - VST: added support for sample rate and buffer size changes
138        - VST: close editor (Fantasia) when the VST is removed
139        - VST: avoid opening Fantasia more than once for each VST instance
140        - VST: export main function as "main" on Linux too (fix for
141          energyXT)
142        - VST: changed number of output channels from one stereo to 16
143          stereo
144        - added channel routing, fxsends and midi maps to the settings
145          stored in the plugin state
146        - performance optimization of AudioChannel::MixTo() and
147          AudioChannel::CopyTo() methods using GCC vector exensions
148          (if available)
149        - ASIO fixes: avoid initializing the device twice, avoid throwing
150          exception when getting parameters from a disconnected device
151    
152      * MIDI driver:
153        - added JACK MIDI driver
154        - dispatch bank select as ordinary CC as well, the user might seriously
155          want to (mis)use it for some purpose ("fixed" in all current MIDI
156          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
157        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
158          CoreMidi or AU
159        - fixed mingw-w64 compilation error in MME driver
160        - made program change handling in MIDI thread real-time safe by
161          moving the logic to a non-RT thread
162        - fixed minor memory leak in ALSA driver
163    
164      * instruments database:
165        - avoid time consuming samples scanning when adding instruments
166          to the instruments database
167        - added support for handling lost files in the instruments database
168        - Implemented option for adding instruments in separate directories
169          in the instruments database
170          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
171        - work-around for missing fnmatch function on Windows to make
172          instrument database compilable
173        - added instrument database support on Windows
174          works with both standalone mode and VST plugin.
175          the instruments DB file is located in
176          %USERPROFILE%\.linuxsampler\instruments.db which allows different
177          databases for each windows user
178          if no DB is present it automatically creates the .linuxsampler subdir
179          and then creates an empty DB
180        - fixed recursive import, which was broken on Windows
181    
182      * Gigasampler format engine:
183        - fixed a memory leak that could happen when a channel was deleted
184          while notes were playing
185        - made it possible to load an instrument even if the audio thread
186          isn't running
187        - added partial support for the "Controller Triggered" MIDI rule,
188          enough for piano gigs with pedal noise samples
189        - minor fix: only mark FX sends as being modified if really the
190          respective FX send MIDI controller was used
191        - added support for GM global device volume SysEx message
192          (can be selected at compile time to either apply globally to the
193          whole sampler [default] or only to the sampler channels that are
194          connected to the respective MIDI input port the SysEx message arrived
195          on)
196        - bugfix: notes triggered at position 0 in the audio buffer were
197          sometimes wrongly killed in the same buffer, causing no sound to
198          be played
199        - added support for chromatic / drumkit mode Roland GS Sysex message
200          which is usally used to switch a part between chromatic sounds and
201          drumkit sounds (as opposed to their common default setting of MIDI
202          part 10 being a drumkit part and all other ones chromatic parts), in
203          LS however one can switch between the first 16 MIDI instrument maps
204          defined for the sampler
205        - made it possible to create multiple sample channels even if the
206          audio thread isn't running
207        - fixed crash when removing channel with active voices (#116)
208        - bugfix: on sample reference changes (instrument editor), only
209          un-cache the respective sample if it's really not used by any
210          sampler engine anymore
211        - re-cache samples in case they were changed by an instrument editor,
212          e.g. when a sample was added while playing (#82)
213        - fixed hanging notes which occured when note-off event had the exact
214          same time stamp as the voice's note-on event and occured both in the
215          same audio fragment cycle (fixes bug #112)
216        - added support for the "fine tune" and "pitch bend range"
217          instrument-level gig parameters
218        - fixed minor artifacts in pitch bend handling
219        - added support for GS Reset SysEx message
220        - allow gig files to use unlimited downward pitch shifting
221        - added a limit check for upward pitch shifting
222        - bugfix: sometimes, when playing a note twice fast, the second
223          note was silent
224        - fixed crash happening when a pitch bend event arrived at the
225          same time a new instrument was loading
226    
227      * LSCP server:
228        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
229          react on MIDI data arriving on certain sampler channels (so far only
230          Note-On and Note-Off events are sent via this LSCP event)
231        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
232          react on MIDI data arriving on certain MIDI input devices (so far only
233          Note-On and Note-Off events are sent via this LSCP event)
234        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
235          SET DB_INSTRUMENT FILE_PATH
236        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
237          frontends to send MIDI messages to specific sampler channel
238        - added two additional fields to GET FILE INSTRUMENT INFO command -
239          KEY_BINDINGS and KEYSWITCH_BINDINGS
240        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
241          was incorrect
242        - Optimized the retrieval of the MIDI instrument mappings
243        - added new LSCP command "SET VOICES" to globally alter the maximum
244          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
245          be triggered respectively
246        - added new LSCP command "SET STREAMS" to globally alter the maximum
247          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
248          which will be triggered respectively
249        - bugfix: retry if "select" returns EINTR (this fixes a crash when
250          a gigedit file dialog is opened)
251        - close all connections when LSCPServer is deleted
252        - hard close of all sockets on exit
253        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
254          driver
255    
256      * Bug fixes:
257        - fixed a crash which occurs when removing a sampler channel waiting
258          to start instrument loading after another channel
259        - fixed a crash which occurs when removing a sampler channel with
260          instrument loading in progress (bug #113)
261        - fixed termination caused by uncaught exception when adding MIDI
262          instrument with PERSISTENT load mode
263        - fixed possible iterator invalidations when resetting the sampler
264        - fixed memory leaks when issuing the following LSCP commands:
265          GET AUDIO_OUTPUT_DRIVER INFO
266          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
267          GET MIDI_INPUT_DRIVER INFO
268          GET MIDI_INPUT_DRIVER_PARAMETER INFO
269        - fixed possible compilation error when sqlite is not present
270        - fixed orphaned pointers when setting maximum voices limit (bug #118)
271        - fixed crash when changing the audio output device of a sampler
272          channel with loaded instrument and start playing notes
273        - fixed endless loop in Engine::SuspendAll() (bug #120)
274        - fixed a low-level atomic load function that was broken on 64-bit
275          PowerPC, which probably could cause crashes on that platform
276        - fixed a memory management error which could cause a crash when a
277          plugin was unloaded
278        - bugfix: two private structs had the same name, which could cause
279          problems if the linker chose the wrong constructor
280        - fixed low-level ConditionServer usage bug that caused lockups on
281          Windows
