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    
51      * SoundFont format engine:
52        - Initial implementation (not usable yet)
53        - RT-safeness: avoid malloc in audio thread
54        - fixed a bug that could cause voice stealing to fail
55    
56      * Host plugins:
57        - AU bugfix: failed to destroy its audio/MIDI devices
58        - Listen to all interfaces on Mac OS X (INADDR_ANY)
59        - VST bugfix: If the host called resume() before and after
60          changing sample rate or block size, the number of channels was
61          incorrectly set to two. This caused silence in Cubase 5.
62    
63      * MIDI driver:
64        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
65          the ALSA sequencer client name

104        unnecessarily long after an update        unnecessarily long after an update
105        - added support for notifying instrument editors on note-on / note-off
106          events (e.g. to highlight the pressed keys on the virtual keyboard
107          of gigedit)
108        - added support for triggering notes by instrument editors (see above)
109        - be verbose on DLL load errors (on Linux)
110        - fixed di-harmonic triangle LFO implementation (this LFO implementation
111          is only used by very few systems, most pick the int math
112          implementation, which is usually faster)
113        - fixes for audio drivers with varying buffer sizes
114        - experimental support for running LinuxSampler as a DSSI, LV2 and
115          VST plugin
116        - notification events for stream/voice count statistics are now sent
117          only when there are actual changes
118        - added memory ordering constraints to improve stability on
119          multi-core and multi-cpu systems
120        - maximum voices and disk streams can now be altered at runtime
121        - fixed CPU feature detection on x86_64 (maybe fixes #108)
122        - automatic stacktrace mechanism is now turned off by default and can
123          be switched on by command line option "--stacktrace" (the automatic
124          stacktrace mechanism seems to be broken on most systems at the moment)
125        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
126          a pointer to the launched InstrumentEditor object
127        - added optional 3rd party user data parameter for following
128          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
129          InstrumentEditor::Launch(),
130          InstrumentManager::LaunchInstrumentEditor()
131        - theoretical fix: made SynchronizedConfig follow C++0x memory

145      - fixed a memory management bug in ASIO driver      - fixed a memory management bug in ASIO driver
146        - Makefile fix: JACK_CFLAGS wasn't used
147        - JACK: use jack_client_open instead of the deprecated
148          jack_client_new
149        - added (experimental) CoreAudio driver
150        - applied old fixes to the ASIO driver that were included in the
151          previous binary release but accidentally never committed to CVS
152          (fixes #117)
153        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
154          win64)
155        - VST: added support for sample rate and buffer size changes
156        - VST: close editor (Fantasia) when the VST is removed
157        - VST: avoid opening Fantasia more than once for each VST instance

159          energyXT)
160        - VST: changed number of output channels from one stereo to 16
161          stereo
162        - added channel routing, fxsends and midi maps to the settings
163          stored in the plugin state
164        - performance optimization of AudioChannel::MixTo() and
165          AudioChannel::CopyTo() methods using GCC vector exensions
166          (if available)
167        - ASIO fixes: avoid initializing the device twice, avoid throwing
168          exception when getting parameters from a disconnected device
169    
170      * MIDI driver:
171        - added JACK MIDI driver
172        - dispatch bank select as ordinary CC as well, the user might seriously
173          want to (mis)use it for some purpose ("fixed" in all current MIDI
174          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
175        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
176          CoreMidi or AU
177        - fixed mingw-w64 compilation error in MME driver
178        - made program change handling in MIDI thread real-time safe by
179          moving the logic to a non-RT thread
180        - fixed minor memory leak in ALSA driver
181    
182    * instruments database:    * instruments database:
183      - avoid time consuming samples scanning when adding instruments      - avoid time consuming samples scanning when adding instruments
184        to the instruments database        to the instruments database
185        - added support for handling lost files in the instruments database
186        - Implemented option for adding instruments in separate directories
187          in the instruments database
188          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
189        - work-around for missing fnmatch function on Windows to make
190          instrument database compilable
191        - added instrument database support on Windows
192          works with both standalone mode and VST plugin.
193          the instruments DB file is located in
194          %USERPROFILE%\.linuxsampler\instruments.db which allows different
195          databases for each windows user
196          if no DB is present it automatically creates the .linuxsampler subdir
197          and then creates an empty DB
198        - fixed recursive import, which was broken on Windows
199    
200    * Gigasampler format engine:    * Gigasampler format engine:
201      - fixed a memory leak that could happen when a channel was deleted      - fixed a memory leak that could happen when a channel was deleted
202        while notes were playing        while notes were playing
203        - made it possible to load an instrument even if the audio thread
204          isn't running
205        - added partial support for the "Controller Triggered" MIDI rule,
206          enough for piano gigs with pedal noise samples
207        - minor fix: only mark FX sends as being modified if really the
208          respective FX send MIDI controller was used
209        - added support for GM global device volume SysEx message
210          (can be selected at compile time to either apply globally to the
211          whole sampler [default] or only to the sampler channels that are
212          connected to the respective MIDI input port the SysEx message arrived
213          on)
214        - bugfix: notes triggered at position 0 in the audio buffer were
215          sometimes wrongly killed in the same buffer, causing no sound to
216          be played
217        - added support for chromatic / drumkit mode Roland GS Sysex message
218          which is usally used to switch a part between chromatic sounds and
219          drumkit sounds (as opposed to their common default setting of MIDI
220          part 10 being a drumkit part and all other ones chromatic parts), in
221          LS however one can switch between the first 16 MIDI instrument maps
222          defined for the sampler
223        - made it possible to create multiple sample channels even if the
224          audio thread isn't running
225        - fixed crash when removing channel with active voices (#116)
226        - bugfix: on sample reference changes (instrument editor), only
227          un-cache the respective sample if it's really not used by any
228          sampler engine anymore
229        - re-cache samples in case they were changed by an instrument editor,
230          e.g. when a sample was added while playing (#82)
231        - fixed hanging notes which occured when note-off event had the exact
232          same time stamp as the voice's note-on event and occured both in the
233          same audio fragment cycle (fixes bug #112)
234        - added support for the "fine tune" and "pitch bend range"
235          instrument-level gig parameters
236        - fixed minor artifacts in pitch bend handling
237        - added support for GS Reset SysEx message
238        - allow gig files to use unlimited downward pitch shifting
239        - added a limit check for upward pitch shifting
240        - bugfix: sometimes, when playing a note twice fast, the second
241          note was silent
242        - fixed crash happening when a pitch bend event arrived at the
243          same time a new instrument was loading
244    
245      * LSCP server:
246        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
247          react on MIDI data arriving on certain sampler channels (so far only
248          Note-On and Note-Off events are sent via this LSCP event)
249        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
250          react on MIDI data arriving on certain MIDI input devices (so far only
251          Note-On and Note-Off events are sent via this LSCP event)
252        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
253          SET DB_INSTRUMENT FILE_PATH
254        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
255          frontends to send MIDI messages to specific sampler channel
256        - added two additional fields to GET FILE INSTRUMENT INFO command -
257          KEY_BINDINGS and KEYSWITCH_BINDINGS
258        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
259          was incorrect
260        - Optimized the retrieval of the MIDI instrument mappings
261        - added new LSCP command "SET VOICES" to globally alter the maximum
262          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
263          be triggered respectively
264        - added new LSCP command "SET STREAMS" to globally alter the maximum
265          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
266          which will be triggered respectively
267        - bugfix: retry if "select" returns EINTR (this fixes a crash when
268          a gigedit file dialog is opened)
269        - close all connections when LSCPServer is deleted
270        - hard close of all sockets on exit
271        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
272          driver
273    
274      * Bug fixes:
275        - fixed a crash which occurs when removing a sampler channel waiting
276          to start instrument loading after another channel
277        - fixed a crash which occurs when removing a sampler channel with
278          instrument loading in progress (bug #113)
279        - fixed termination caused by uncaught exception when adding MIDI
280          instrument with PERSISTENT load mode
281        - fixed possible iterator invalidations when resetting the sampler
282        - fixed memory leaks when issuing the following LSCP commands:
283          GET AUDIO_OUTPUT_DRIVER INFO
284          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
285          GET MIDI_INPUT_DRIVER INFO
286          GET MIDI_INPUT_DRIVER_PARAMETER INFO
287        - fixed possible compilation error when sqlite is not present
288        - fixed orphaned pointers when setting maximum voices limit (bug #118)
289        - fixed crash when changing the audio output device of a sampler
290          channel with loaded instrument and start playing notes
291        - fixed endless loop in Engine::SuspendAll() (bug #120)
292        - fixed a low-level atomic load function that was broken on 64-bit
293          PowerPC, which probably could cause crashes on that platform
294        - fixed a memory management error which could cause a crash when a
295          plugin was unloaded
296        - bugfix: two private structs had the same name, which could cause
297          problems if the linker chose the wrong constructor
298        - fixed low-level ConditionServer usage bug that caused lockups on
299          Windows
