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        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
16        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
17        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
18          note (in this implementation of the sampler its simply hard routed to
19          the 1st effect send of the sampler channel, no matter what the actual
20          effect type is)
21        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
22          note (in this implementation of the sampler its simply hard routed to
23          the 2nd effect send of the sampler channel, no matter what the actual
24          effect type is)
25    
26      * Gigasampler format engine:
27        - implemented the "round robin keyboard" dimension
28        - fixed round robin and random dimensions for cases when number of
29          dimension zones is not a power of two
30        - made round robin use a counter for each region instead of each
31          key
32    
33      * SFZ format engine:
34        - Initial implementation (not usable yet)
35        - added support for v2 multiple stage envelope generators
36        - added a fine-tuned v1 envelope generator instead of using the
37          one from the gig engine
38        - fixed memory leak and memory handling errors
39        - added support for trigger=first, trigger=legato and sw_previous
40        - allow non-numerical key values ("C#4" for example)
41        - "key" opcode now sets pitch_keycenter too
42        - fixed error when unloading instrument with same sample used by
43          multiple regions
44        - added some opcode aliases, like loopmode for loop_mode, to be
45          more compatible
46        - added support for trigger=release and rt_decay
47        - added support for off_mode=normal
48        - added support for random, seq_position, seq_length and volume
49        - added v1 LFO opcodes to parser (no support in engine yet)
50        - added support for amp_veltrack and amp_velcurve_N
51        - fine-tuned the default velocity curve
52        - added support for transpose
53        - fixed crash when using sw_down/up
54        - improved logic for sw_lokey/hikey/up/down/last
55        - added more v1 aliases to parser
56        - reduced memory usage for sfz data
57        - RT-safeness: avoid malloc in audio thread
58        - fixed a bug that could cause voice stealing to fail
59        - optimized sample lookup
60        - improved support for exclusive groups (group, off_by and
61          off_mode)
62        - added support for controller triggered regions (on_locc/on_hicc)
63        - added support for loop_mode=one_shot
64        - fixed playback of 16 bit wav files on big endian CPUs
65        - added support for Ogg Vorbis sample files
66    
67      * SoundFont format engine:
68        - Initial implementation (not usable yet)
69        - RT-safeness: avoid malloc in audio thread
70        - fixed a bug that could cause voice stealing to fail
71    
72      * Host plugins:
73        - AU bugfix: failed to destroy its audio/MIDI devices
74        - Listen to all interfaces on Mac OS X (INADDR_ANY)
75        - VST bugfix: If the host called resume() before and after
76          changing sample rate or block size, the number of channels was
77          incorrectly set to two. This caused silence in Cubase 5.
78    
79      * MIDI driver:
80        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
81          the ALSA sequencer client name
82    
83      * LSCP server:
84        - added support for sending MIDI CC messages via LSCP command
85          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
86    
87      * Bug fixes:
88        - Fixed crash which may occur when MIDI key + transpose is out of range
89        - minor valgrind fixes
90    
91    Version 1.0.0 (31 July 2009)
92    
93      * packaging changes:
94        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
95          causing e.g. the libgig test to fail when
96          "./configure --disable-jack-driver" was used
97          (patch by Alexis Ballier)
98        - fixed compilation with gcc 4.3
99        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
100        - fixed configure so it detects x86_64 (#107)
101        - fixes for building with newer MinGW versions
102        - fix for building with bison 2.4 (#111)
103        - fixed building with libgig installed in a non-standard directory
104        - minor fix in configure for mmsystem.h detection on MinGW
105        - Windows: look for editor plugins and Fantasia using base
106          directory of liblinuxsampler dll (look in the same directory and one
107          directory above)
108        - configure script fix: removed unconditional use of SSE
109        - fixed building with sqlite installed in a non-standard directory
110        - when cross-compiling, don't try to create instruments.db
111        - fix for new mingw-w64 version, which has usleep
112    
113      * general changes:
114        - bugfix: on some POSIX systems instrument editor plugins refused to
115          load as we used a non-portable Linux specific struct field
116          (fixes bug #70, patch by Ronald Baljeu)
117        - fixed endless loop which occured when loading an instrument editor
118          plugin DLL on Windows systems failed
119        - fixed memory leaks that occurred when liblinuxsampler was unloaded
120        - optimized the SynchronizedConfig class so it doesn't wait
121          unnecessarily long after an update
122        - added support for notifying instrument editors on note-on / note-off
123          events (e.g. to highlight the pressed keys on the virtual keyboard
124          of gigedit)
125        - added support for triggering notes by instrument editors (see above)
126        - be verbose on DLL load errors (on Linux)
127        - fixed di-harmonic triangle LFO implementation (this LFO implementation
128          is only used by very few systems, most pick the int math
129          implementation, which is usually faster)
130        - fixes for audio drivers with varying buffer sizes
131        - experimental support for running LinuxSampler as a DSSI, LV2 and
132          VST plugin
133        - notification events for stream/voice count statistics are now sent
134          only when there are actual changes
135        - added memory ordering constraints to improve stability on
136          multi-core and multi-cpu systems
137        - maximum voices and disk streams can now be altered at runtime
138        - fixed CPU feature detection on x86_64 (maybe fixes #108)
139        - automatic stacktrace mechanism is now turned off by default and can
140          be switched on by command line option "--stacktrace" (the automatic
141          stacktrace mechanism seems to be broken on most systems at the moment)
142        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
143          a pointer to the launched InstrumentEditor object
144        - added optional 3rd party user data parameter for following
145          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
146          InstrumentEditor::Launch(),
147          InstrumentManager::LaunchInstrumentEditor()
148        - theoretical fix: made SynchronizedConfig follow C++0x memory
149          model more strictly
150        - fixes for using large audio device buffers
151        - Windows: add the installation directory to the DLL search path
152          when loading an editor plugin (solves problems with VST and
153          gigedit on systems with other GTK versions installed)
154    
155      * audio driver:
156        - removed the nonsense audio channel constraint (which was hard coded to
157          max. 100 audio channels) for most audio drivers
158        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
159          opposed to the LSCP specs
160        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
161          reflected the wrong value
162        - fixed a memory management bug in ASIO driver
163        - Makefile fix: JACK_CFLAGS wasn't used
164        - JACK: use jack_client_open instead of the deprecated
165          jack_client_new
166        - added (experimental) CoreAudio driver
167        - applied old fixes to the ASIO driver that were included in the
168          previous binary release but accidentally never committed to CVS
169          (fixes #117)
170        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
171          win64)
172        - VST: added support for sample rate and buffer size changes
173        - VST: close editor (Fantasia) when the VST is removed
174        - VST: avoid opening Fantasia more than once for each VST instance
175        - VST: export main function as "main" on Linux too (fix for
176          energyXT)
177        - VST: changed number of output channels from one stereo to 16
178          stereo
179        - added channel routing, fxsends and midi maps to the settings
180          stored in the plugin state
181        - performance optimization of AudioChannel::MixTo() and
182          AudioChannel::CopyTo() methods using GCC vector exensions
183          (if available)
184        - ASIO fixes: avoid initializing the device twice, avoid throwing
185          exception when getting parameters from a disconnected device
186    
187      * MIDI driver:
188        - added JACK MIDI driver
189        - dispatch bank select as ordinary CC as well, the user might seriously
190          want to (mis)use it for some purpose ("fixed" in all current MIDI
191          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
192        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
193          CoreMidi or AU
194        - fixed mingw-w64 compilation error in MME driver
195        - made program change handling in MIDI thread real-time safe by
196          moving the logic to a non-RT thread
197        - fixed minor memory leak in ALSA driver
198    
199      * instruments database:
200        - avoid time consuming samples scanning when adding instruments
201          to the instruments database
202        - added support for handling lost files in the instruments database
203        - Implemented option for adding instruments in separate directories
204          in the instruments database
205          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
206        - work-around for missing fnmatch function on Windows to make
207          instrument database compilable
208        - added instrument database support on Windows
209          works with both standalone mode and VST plugin.
210          the instruments DB file is located in
211          %USERPROFILE%\.linuxsampler\instruments.db which allows different
212          databases for each windows user
213          if no DB is present it automatically creates the .linuxsampler subdir
214          and then creates an empty DB
215        - fixed recursive import, which was broken on Windows
216    
217      * Gigasampler format engine:
218        - fixed a memory leak that could happen when a channel was deleted
219          while notes were playing
220        - made it possible to load an instrument even if the audio thread
221          isn't running
222        - added partial support for the "Controller Triggered" MIDI rule,
223          enough for piano gigs with pedal noise samples
224        - minor fix: only mark FX sends as being modified if really the
225          respective FX send MIDI controller was used
226        - added support for GM global device volume SysEx message
227          (can be selected at compile time to either apply globally to the
228          whole sampler [default] or only to the sampler channels that are
229          connected to the respective MIDI input port the SysEx message arrived
230          on)
231        - bugfix: notes triggered at position 0 in the audio buffer were
232          sometimes wrongly killed in the same buffer, causing no sound to
233          be played
234        - added support for chromatic / drumkit mode Roland GS Sysex message
235          which is usally used to switch a part between chromatic sounds and
236          drumkit sounds (as opposed to their common default setting of MIDI
237          part 10 being a drumkit part and all other ones chromatic parts), in
238          LS however one can switch between the first 16 MIDI instrument maps
239          defined for the sampler
240        - made it possible to create multiple sample channels even if the
241          audio thread isn't running
242        - fixed crash when removing channel with active voices (#116)
243        - bugfix: on sample reference changes (instrument editor), only
244          un-cache the respective sample if it's really not used by any
245          sampler engine anymore
246        - re-cache samples in case they were changed by an instrument editor,
247          e.g. when a sample was added while playing (#82)
248        - fixed hanging notes which occured when note-off event had the exact
249          same time stamp as the voice's note-on event and occured both in the
250          same audio fragment cycle (fixes bug #112)
251        - added support for the "fine tune" and "pitch bend range"
252          instrument-level gig parameters
253        - fixed minor artifacts in pitch bend handling
254        - added support for GS Reset SysEx message
255        - allow gig files to use unlimited downward pitch shifting
256        - added a limit check for upward pitch shifting
257        - bugfix: sometimes, when playing a note twice fast, the second
258          note was silent
259        - fixed crash happening when a pitch bend event arrived at the
260          same time a new instrument was loading
261    
262      * LSCP server:
263        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
264          react on MIDI data arriving on certain sampler channels (so far only
265          Note-On and Note-Off events are sent via this LSCP event)
266        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
267          react on MIDI data arriving on certain MIDI input devices (so far only
268          Note-On and Note-Off events are sent via this LSCP event)
269        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
270          SET DB_INSTRUMENT FILE_PATH
271        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
272          frontends to send MIDI messages to specific sampler channel
273        - added two additional fields to GET FILE INSTRUMENT INFO command -
274          KEY_BINDINGS and KEYSWITCH_BINDINGS
275        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
276          was incorrect
277        - Optimized the retrieval of the MIDI instrument mappings
278        - added new LSCP command "SET VOICES" to globally alter the maximum
279          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
280          be triggered respectively
281        - added new LSCP command "SET STREAMS" to globally alter the maximum
282          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
283          which will be triggered respectively
284        - bugfix: retry if "select" returns EINTR (this fixes a crash when
285          a gigedit file dialog is opened)
286        - close all connections when LSCPServer is deleted
287        - hard close of all sockets on exit
288        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
289          driver
290    
291      * Bug fixes:
292        - fixed a crash which occurs when removing a sampler channel waiting
293          to start instrument loading after another channel
294        - fixed a crash which occurs when removing a sampler channel with
295          instrument loading in progress (bug #113)
296        - fixed termination caused by uncaught exception when adding MIDI
297          instrument with PERSISTENT load mode
298        - fixed possible iterator invalidations when resetting the sampler
299        - fixed memory leaks when issuing the following LSCP commands:
300          GET AUDIO_OUTPUT_DRIVER INFO
301          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
302          GET MIDI_INPUT_DRIVER INFO
303          GET MIDI_INPUT_DRIVER_PARAMETER INFO
304        - fixed possible compilation error when sqlite is not present
305        - fixed orphaned pointers when setting maximum voices limit (bug #118)
306        - fixed crash when changing the audio output device of a sampler
307          channel with loaded instrument and start playing notes
308        - fixed endless loop in Engine::SuspendAll() (bug #120)
309        - fixed a low-level atomic load function that was broken on 64-bit
310          PowerPC, which probably could cause crashes on that platform
311        - fixed a memory management error which could cause a crash when a
312          plugin was unloaded
313        - bugfix: two private structs had the same name, which could cause
314          problems if the linker chose the wrong constructor
315        - fixed low-level ConditionServer usage bug that caused lockups on
316          Windows
317
