3    * packaging changes:    * packaging changes:
4        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5          causing e.g. the libgig test to fail when
6          "./configure --disable-jack-driver" was used
7          (patch by Alexis Ballier)
8        - fixed compilation with gcc 4.3
9        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10        - fixed configure so it detects x86_64 (#107)
11        - fixes for building with newer MinGW versions
12        - fix for building with bison 2.4 (#111)
13        - fixed building with libgig installed in a non-standard directory
14        - minor fix in configure for mmsystem.h detection on MinGW
15        - Windows: look for editor plugins and Fantasia using base
16          directory of liblinuxsampler dll (look in the same directory and one
17          directory above)
18        - configure script fix: removed unconditional use of SSE
19        - fixed building with sqlite installed in a non-standard directory
20    
21      * general changes:
22        - bugfix: on some POSIX systems instrument editor plugins refused to
23          load as we used a non-portable Linux specific struct field
24          (fixes bug #70, patch by Ronald Baljeu)
25        - fixed endless loop which occured when loading an instrument editor
26          plugin DLL on Windows systems failed
27        - fixed memory leaks that occurred when liblinuxsampler was unloaded
28        - optimized the SynchronizedConfig class so it doesn't wait
29          unnecessarily long after an update
30        - added support for notifying instrument editors on note-on / note-off
31          events (e.g. to highlight the pressed keys on the virtual keyboard
32          of gigedit)
33        - added support for triggering notes by instrument editors (see above)
34        - be verbose on DLL load errors (on Linux)
35        - fixed di-harmonic triangle LFO implementation (this LFO implementation
36          is only used by very few systems, most pick the int math
37          implementation, which is usually faster)
38        - fixes for audio drivers with varying buffer sizes
39        - experimental support for running LinuxSampler as a DSSI, LV2 and
40          VST plugin
41        - notification events for stream/voice count statistics are now sent
42          only when there are actual changes
43        - added memory ordering constraints to improve stability on
44          multi-core and multi-cpu systems
45        - maximum voices and disk streams can now be altered at runtime
46        - fixed CPU feature detection on x86_64 (maybe fixes #108)
47        - automatic stacktrace mechanism is now turned off by default and can
48          be switched on by command line option "--stacktrace" (the automatic
49          stacktrace mechanism seems to be broken on most systems at the moment)
50        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
51          a pointer to the launched InstrumentEditor object
52        - added optional 3rd party user data parameter for following
53          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
54          InstrumentEditor::Launch(),
55          InstrumentManager::LaunchInstrumentEditor()
56        - theoretical fix: made SynchronizedConfig follow C++0x memory
57          model more strictly
58        - fixes for using large audio device buffers
59    
60      * audio driver:
61        - removed the nonsense audio channel constraint (which was hard coded to
62          max. 100 audio channels) for most audio drivers
63        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
64          opposed to the LSCP specs
65        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
66          reflected the wrong value
67        - fixed a memory management bug in ASIO driver
68        - Makefile fix: JACK_CFLAGS wasn't used
69        - JACK: use jack_client_open instead of the deprecated
70          jack_client_new
71        - added (experimental) CoreAudio driver
72        - applied old fixes to the ASIO driver that were included in the
73          previous binary release but accidentally never committed to CVS
74          (fixes #117)
75        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
76          win64)
77        - VST: added support for sample rate and buffer size changes
78        - VST: close editor (Fantasia) when the VST is removed
79        - VST: avoid opening Fantasia more than once for each VST instance
80        - VST: export main function as "main" on Linux too (fix for
81          energyXT)
82        - VST: changed number of output channels from one stereo to 16
83          stereo
84        - added channel routing, fxsends and midi maps to the settings
85          stored in the plugin state
86        - performance optimization of AudioChannel::MixTo() and
87          AudioChannel::CopyTo() methods using GCC vector exensions
88          (if available)
89    
90      * MIDI driver:
91        - added JACK MIDI driver
92        - dispatch bank select as ordinary CC as well, the user might seriously
93          want to (mis)use it for some purpose ("fixed" in all current MIDI
94          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
95        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
96          CoreMidi or AU
97        - fixed mingw-w64 compilation error in MME driver
98        - made program change handling in MIDI thread real-time safe by
99          moving the logic to a non-RT thread
100    
101      * instruments database:
102        - avoid time consuming samples scanning when adding instruments
103          to the instruments database
104        - added support for handling lost files in the instruments database
105        - Implemented option for adding instruments in separate directories
106          in the instruments database
107          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
108        - work-around for missing fnmatch function on Windows to make
109          instrument database compilable
110        - added instrument database support on Windows
111          works with both standalone mode and VST plugin.
112          the instruments DB file is located in
113          %USERPROFILE%\.linuxsampler\instruments.db which allows different
114          databases for each windows user
115          if no DB is present it automatically creates the .linuxsampler subdir
116          and then creates an empty DB
117    
118      * Gigasampler format engine:
119        - fixed a memory leak that could happen when a channel was deleted
120          while notes were playing
121        - made it possible to load an instrument even if the audio thread
122          isn't running
123        - added partial support for the "Controller Triggered" MIDI rule,
124          enough for piano gigs with pedal noise samples
125        - minor fix: only mark FX sends as being modified if really the
126          respective FX send MIDI controller was used
127        - added support for GM global device volume SysEx message
128          (can be selected at compile time to either apply globally to the
129          whole sampler [default] or only to the sampler channels that are
130          connected to the respective MIDI input port the SysEx message arrived
131          on)
132        - bugfix: notes triggered at position 0 in the audio buffer were
133          sometimes wrongly killed in the same buffer, causing no sound to
134          be played
135        - added support for chromatic / drumkit mode Roland GS Sysex message
136          which is usally used to switch a part between chromatic sounds and
137          drumkit sounds (as opposed to their common default setting of MIDI
138          part 10 being a drumkit part and all other ones chromatic parts), in
139          LS however one can switch between the first 16 MIDI instrument maps
140          defined for the sampler
141        - made it possible to create multiple sample channels even if the
142          audio thread isn't running
143        - fixed crash when removing channel with active voices (#116)
144        - bugfix: on sample reference changes (instrument editor), only
145          un-cache the respective sample if it's really not used by any
146          sampler engine anymore
147        - re-cache samples in case they were changed by an instrument editor,
148          e.g. when a sample was added while playing (#82)
149        - fixed hanging notes which occured when note-off event had the exact
150          same time stamp as the voice's note-on event and occured both in the
151          same audio fragment cycle (fixes bug #112)
152        - added support for the "fine tune" and "pitch bend range"
153          instrument-level gig parameters
154        - fixed minor artifacts in pitch bend handling
155        - added support for GS Reset SysEx message
156        - allow gig files to use unlimited downward pitch shifting
157        - added a limit check for upward pitch shifting
158        - bugfix: sometimes, when playing a note twice fast, the second
159          note was silent
160        - fixed crash happening when a pitch bend event arrived at the
161          same time a new instrument was loading
162    
163      * LSCP server:
164        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
165          react on MIDI data arriving on certain sampler channels (so far only
166          Note-On and Note-Off events are sent via this LSCP event)
167        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
168          react on MIDI data arriving on certain MIDI input devices (so far only
169          Note-On and Note-Off events are sent via this LSCP event)
170        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
171          SET DB_INSTRUMENT FILE_PATH
172        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
173          frontends to send MIDI messages to specific sampler channel
174        - added two additional fields to GET FILE INSTRUMENT INFO command -
175          KEY_BINDINGS and KEYSWITCH_BINDINGS
176        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
177          was incorrect
178        - Optimized the retrieval of the MIDI instrument mappings
179        - added new LSCP command "SET VOICES" to globally alter the maximum
180          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
181          be triggered respectively
182        - added new LSCP command "SET STREAMS" to globally alter the maximum
183          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
184          which will be triggered respectively
185        - bugfix: retry if "select" returns EINTR (this fixes a crash when
186          a gigedit file dialog is opened)
187        - close all connections when LSCPServer is deleted
188        - hard close of all sockets on exit
189        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
190          driver
191    
192      * Bug fixes:
193        - fixed a crash which occurs when removing a sampler channel waiting
194          to start instrument loading after another channel
195        - fixed a crash which occurs when removing a sampler channel with
196          instrument loading in progress (bug #113)
197        - fixed termination caused by uncaught exception when adding MIDI
198          instrument with PERSISTENT load mode
199        - fixed possible iterator invalidations when resetting the sampler
200        - fixed memory leaks when issuing the following LSCP commands:
201          GET AUDIO_OUTPUT_DRIVER INFO
202          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
203          GET MIDI_INPUT_DRIVER INFO
204          GET MIDI_INPUT_DRIVER_PARAMETER INFO
205        - fixed possible compilation error when sqlite is not present
206        - fixed orphaned pointers when setting maximum voices limit (bug #118)
207        - fixed crash when changing the audio output device of a sampler
208          channel with loaded instrument and start playing notes
209        - fixed endless loop in Engine::SuspendAll() (bug #120)
210        - fixed a low-level atomic load function that was broken on 64-bit
211          PowerPC, which probably could cause crashes on that platform
212        - fixed a memory management error which could cause a crash when a
213          plugin was unloaded
214        - bugfix: two private structs had the same name, which could cause
215          problems if the linker chose the wrong constructor
216
