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    
55      * SoundFont format engine:
56        - Initial implementation (not usable yet)
57        - RT-safeness: avoid malloc in audio thread
58        - fixed a bug that could cause voice stealing to fail
59    
60      * Host plugins:
61        - AU bugfix: failed to destroy its audio/MIDI devices
62        - Listen to all interfaces on Mac OS X (INADDR_ANY)
63        - VST bugfix: If the host called resume() before and after
64          changing sample rate or block size, the number of channels was
65          incorrectly set to two. This caused silence in Cubase 5.
66    
67      * MIDI driver:
68        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
69          the ALSA sequencer client name

109        unnecessarily long after an update        unnecessarily long after an update
110        - added support for notifying instrument editors on note-on / note-off
111          events (e.g. to highlight the pressed keys on the virtual keyboard
112          of gigedit)
113        - added support for triggering notes by instrument editors (see above)
114        - be verbose on DLL load errors (on Linux)
115        - fixed di-harmonic triangle LFO implementation (this LFO implementation
116          is only used by very few systems, most pick the int math
117          implementation, which is usually faster)
118        - fixes for audio drivers with varying buffer sizes
119        - experimental support for running LinuxSampler as a DSSI, LV2 and
120          VST plugin
121        - notification events for stream/voice count statistics are now sent
122          only when there are actual changes

125        - maximum voices and disk streams can now be altered at runtime
126        - fixed CPU feature detection on x86_64 (maybe fixes #108)
127        - automatic stacktrace mechanism is now turned off by default and can
128          be switched on by command line option "--stacktrace" (the automatic
129          stacktrace mechanism seems to be broken on most systems at the moment)
130        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
131          a pointer to the launched InstrumentEditor object
132        - added optional 3rd party user data parameter for following
133          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
134          InstrumentEditor::Launch(),
135          InstrumentManager::LaunchInstrumentEditor()
136        - theoretical fix: made SynchronizedConfig follow C++0x memory

151        - Makefile fix: JACK_CFLAGS wasn't used
152        - JACK: use jack_client_open instead of the deprecated
153          jack_client_new
154        - added (experimental) CoreAudio driver
155        - applied old fixes to the ASIO driver that were included in the
156          previous binary release but accidentally never committed to CVS
157          (fixes #117)
158        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
159          win64)
160        - VST: added support for sample rate and buffer size changes
161        - VST: close editor (Fantasia) when the VST is removed
162        - VST: avoid opening Fantasia more than once for each VST instance
163        - VST: export main function as "main" on Linux too (fix for
164          energyXT)

166          stereo
167        - added channel routing, fxsends and midi maps to the settings
168          stored in the plugin state
169        - performance optimization of AudioChannel::MixTo() and
170          AudioChannel::CopyTo() methods using GCC vector exensions
171          (if available)
172        - ASIO fixes: avoid initializing the device twice, avoid throwing
173          exception when getting parameters from a disconnected device
174    
175      * MIDI driver:
176        - added JACK MIDI driver
177        - dispatch bank select as ordinary CC as well, the user might seriously
178          want to (mis)use it for some purpose ("fixed" in all current MIDI
179          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
180        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
181          CoreMidi or AU
182        - fixed mingw-w64 compilation error in MME driver
183        - made program change handling in MIDI thread real-time safe by
184          moving the logic to a non-RT thread

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