3    * packaging changes:    * packaging changes:
4        - fixed building with newer MinGW-w64
5    
6      * general changes:
7        - Refactoring: moved the independent code from
8          the Gigasampler format engine to base classes
9        - command line option '--profile' is currently disabled, since the
10          respective profiling code is currently broken
11        - Introduced support for optional environment variable
12          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
13          where the sampler shall look for instrument editor plugins
14          (patch by Luis Garrido, slightly modified).
15    
16      * Gigasampler format engine:
17        - implemented the "round robin keyboard" dimension
18        - fixed round robin and random dimensions for cases when number of
19          dimension zones is not a power of two
20        - made round robin use a counter for each region instead of each
21          key
22    
23      * SFZ format engine:
24        - Initial implementation (not usable yet)
25        - added support for v2 multiple stage envelope generators
26        - added a fine-tuned v1 envelope generator instead of using the
27          one from the gig engine
28        - fixed memory leak and memory handling errors
29        - added support for trigger=first, trigger=legato and sw_previous
30        - allow non-numerical key values ("C#4" for example)
31        - "key" opcode now sets pitch_keycenter too
32        - fixed error when unloading instrument with same sample used by
33          multiple regions
34        - added some opcode aliases, like loopmode for loop_mode, to be
35          more compatible
36        - added support for trigger=release and rt_decay
37        - added support for off_mode=normal
38        - added support for random, seq_position, seq_length and volume
39        - added v1 LFO opcodes to parser (no support in engine yet)
40        - added support for amp_veltrack and amp_velcurve_N
41        - fine-tuned the default velocity curve
42        - added support for transpose
43        - fixed crash when using sw_down/up
44        - improved logic for sw_lokey/hikey/up/down/last
45        - added more v1 aliases to parser
46        - reduced memory usage for sfz data
47        - RT-safeness: avoid malloc in audio thread
48        - fixed a bug that could cause voice stealing to fail
49        - optimized sample lookup
50        - improved support for exclusive groups (group, off_by and
51          off_mode)
52        - added support for controller triggered regions (on_locc/on_hicc)
53        - added support for loop_mode=one_shot
54        - fixed playback of 16 bit wav files on big endian CPUs
55        - added support for Ogg Vorbis sample files
56    
57      * SoundFont format engine:

60        - fixed a bug that could cause voice stealing to fail
61    
62      * Host plugins:
63        - AU bugfix: failed to destroy its audio/MIDI devices
64        - Listen to all interfaces on Mac OS X (INADDR_ANY)
65        - VST bugfix: If the host called resume() before and after
66          changing sample rate or block size, the number of channels was
67          incorrectly set to two. This caused silence in Cubase 5.
68    
69      * MIDI driver:
70        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
71          the ALSA sequencer client name

109        - fixed memory leaks that occurred when liblinuxsampler was unloaded
110        - optimized the SynchronizedConfig class so it doesn't wait
111          unnecessarily long after an update
112        - added support for notifying instrument editors on note-on / note-off
113          events (e.g. to highlight the pressed keys on the virtual keyboard
114          of gigedit)
115        - added support for triggering notes by instrument editors (see above)
116        - be verbose on DLL load errors (on Linux)
117        - fixed di-harmonic triangle LFO implementation (this LFO implementation
118          is only used by very few systems, most pick the int math
119          implementation, which is usually faster)
120        - fixes for audio drivers with varying buffer sizes
121        - experimental support for running LinuxSampler as a DSSI, LV2 and
122          VST plugin
123        - notification events for stream/voice count statistics are now sent
124          only when there are actual changes
125        - added memory ordering constraints to improve stability on
126          multi-core and multi-cpu systems
127        - maximum voices and disk streams can now be altered at runtime
128        - fixed CPU feature detection on x86_64 (maybe fixes #108)
129        - automatic stacktrace mechanism is now turned off by default and can
130          be switched on by command line option "--stacktrace" (the automatic
131          stacktrace mechanism seems to be broken on most systems at the moment)
132        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
133          a pointer to the launched InstrumentEditor object
134        - added optional 3rd party user data parameter for following
135          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
136          InstrumentEditor::Launch(),
137          InstrumentManager::LaunchInstrumentEditor()
138        - theoretical fix: made SynchronizedConfig follow C++0x memory

152        - fixed a memory management bug in ASIO driver
153        - Makefile fix: JACK_CFLAGS wasn't used
154        - JACK: use jack_client_open instead of the deprecated
155          jack_client_new
156        - added (experimental) CoreAudio driver
157        - applied old fixes to the ASIO driver that were included in the
158          previous binary release but accidentally never committed to CVS
159          (fixes #117)
160        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
161          win64)
162        - VST: added support for sample rate and buffer size changes
163        - VST: close editor (Fantasia) when the VST is removed
164        - VST: avoid opening Fantasia more than once for each VST instance
165        - VST: export main function as "main" on Linux too (fix for
166          energyXT)
167        - VST: changed number of output channels from one stereo to 16
168          stereo
169        - added channel routing, fxsends and midi maps to the settings
170          stored in the plugin state
171        - performance optimization of AudioChannel::MixTo() and
172          AudioChannel::CopyTo() methods using GCC vector exensions
173          (if available)
174        - ASIO fixes: avoid initializing the device twice, avoid throwing
175          exception when getting parameters from a disconnected device
176    
177      * MIDI driver:
178        - added JACK MIDI driver
179        - dispatch bank select as ordinary CC as well, the user might seriously
180          want to (mis)use it for some purpose ("fixed" in all current MIDI
181          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
182        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
183          CoreMidi or AU
184        - fixed mingw-w64 compilation error in MME driver
185        - made program change handling in MIDI thread real-time safe by
186          moving the logic to a non-RT thread
187        - fixed minor memory leak in ALSA driver
188    
189    * instruments database:    * instruments database:
190      - avoid time consuming samples scanning when adding instruments      - avoid time consuming samples scanning when adding instruments
191        to the instruments database        to the instruments database
192        - added support for handling lost files in the instruments database
193        - Implemented option for adding instruments in separate directories
194          in the instruments database
195          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
196        - work-around for missing fnmatch function on Windows to make
197          instrument database compilable
198        - added instrument database support on Windows
199          works with both standalone mode and VST plugin.
200          the instruments DB file is located in
201          %USERPROFILE%\.linuxsampler\instruments.db which allows different
202          databases for each windows user
203          if no DB is present it automatically creates the .linuxsampler subdir
204          and then creates an empty DB
205        - fixed recursive import, which was broken on Windows
206    
207      * Gigasampler format engine:
208        - fixed a memory leak that could happen when a channel was deleted
209          while notes were playing
210        - made it possible to load an instrument even if the audio thread
211          isn't running
212        - added partial support for the "Controller Triggered" MIDI rule,
213          enough for piano gigs with pedal noise samples
214        - minor fix: only mark FX sends as being modified if really the
215          respective FX send MIDI controller was used
216        - added support for GM global device volume SysEx message
217          (can be selected at compile time to either apply globally to the
218          whole sampler [default] or only to the sampler channels that are
219          connected to the respective MIDI input port the SysEx message arrived
220          on)
221        - bugfix: notes triggered at position 0 in the audio buffer were
222          sometimes wrongly killed in the same buffer, causing no sound to
223          be played
224        - added support for chromatic / drumkit mode Roland GS Sysex message
225          which is usally used to switch a part between chromatic sounds and
226          drumkit sounds (as opposed to their common default setting of MIDI
227          part 10 being a drumkit part and all other ones chromatic parts), in
228          LS however one can switch between the first 16 MIDI instrument maps
229          defined for the sampler
230        - made it possible to create multiple sample channels even if the
231          audio thread isn't running
232        - fixed crash when removing channel with active voices (#116)
233        - bugfix: on sample reference changes (instrument editor), only
234          un-cache the respective sample if it's really not used by any
235          sampler engine anymore
236        - re-cache samples in case they were changed by an instrument editor,
237          e.g. when a sample was added while playing (#82)
238        - fixed hanging notes which occured when note-off event had the exact
239          same time stamp as the voice's note-on event and occured both in the
240          same audio fragment cycle (fixes bug #112)
241        - added support for the "fine tune" and "pitch bend range"
242          instrument-level gig parameters
243        - fixed minor artifacts in pitch bend handling
244        - added support for GS Reset SysEx message
245        - allow gig files to use unlimited downward pitch shifting
246        - added a limit check for upward pitch shifting
247        - bugfix: sometimes, when playing a note twice fast, the second
248          note was silent
249        - fixed crash happening when a pitch bend event arrived at the
250          same time a new instrument was loading
251    
252      * LSCP server:
253        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
254          react on MIDI data arriving on certain sampler channels (so far only
255          Note-On and Note-Off events are sent via this LSCP event)
256        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
257          react on MIDI data arriving on certain MIDI input devices (so far only
258          Note-On and Note-Off events are sent via this LSCP event)
259        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
260          SET DB_INSTRUMENT FILE_PATH
261        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
262          frontends to send MIDI messages to specific sampler channel
263        - added two additional fields to GET FILE INSTRUMENT INFO command -
264          KEY_BINDINGS and KEYSWITCH_BINDINGS
265        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
266          was incorrect
267        - Optimized the retrieval of the MIDI instrument mappings
268        - added new LSCP command "SET VOICES" to globally alter the maximum
269          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
270          be triggered respectively
271        - added new LSCP command "SET STREAMS" to globally alter the maximum
272          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
273          which will be triggered respectively
274        - bugfix: retry if "select" returns EINTR (this fixes a crash when
275          a gigedit file dialog is opened)
276        - close all connections when LSCPServer is deleted
277        - hard close of all sockets on exit
278        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
279          driver
280    
281      * Bug fixes:
282        - fixed a crash which occurs when removing a sampler channel waiting
283          to start instrument loading after another channel
284        - fixed a crash which occurs when removing a sampler channel with
285          instrument loading in progress (bug #113)
286        - fixed termination caused by uncaught exception when adding MIDI
287          instrument with PERSISTENT load mode
288        - fixed possible iterator invalidations when resetting the sampler
289        - fixed memory leaks when issuing the following LSCP commands:
290          GET AUDIO_OUTPUT_DRIVER INFO
291          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
292          GET MIDI_INPUT_DRIVER INFO
293          GET MIDI_INPUT_DRIVER_PARAMETER INFO
294        - fixed possible compilation error when sqlite is not present
295        - fixed orphaned pointers when setting maximum voices limit (bug #118)
296        - fixed crash when changing the audio output device of a sampler
297          channel with loaded instrument and start playing notes
298        - fixed endless loop in Engine::SuspendAll() (bug #120)
299        - fixed a low-level atomic load function that was broken on 64-bit
300          PowerPC, which probably could cause crashes on that platform
301        - fixed a memory management error which could cause a crash when a
302          plugin was unloaded
303        - bugfix: two private structs had the same name, which could cause
304          problems if the linker chose the wrong constructor
305        - fixed low-level ConditionServer usage bug that caused lockups on
306          Windows
