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