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    
15      * general changes:
16        - bugfix: on some POSIX systems instrument editor plugins refused to
17          load as we used a non-portable Linux specific struct field
18          (fixes bug #70, patch by Ronald Baljeu)
19        - fixed endless loop which occured when loading an instrument editor
20          plugin DLL on Windows systems failed
21        - fixed memory leaks that occurred when liblinuxsampler was unloaded
22        - optimized the SynchronizedConfig class so it doesn't wait
23          unnecessarily long after an update
24        - added support for notifying instrument editors on note-on / note-off
25          events (e.g. to highlight the pressed keys on the virtual keyboard
26          of gigedit)
27        - added support for triggering notes by instrument editors (see above)
28        - be verbose on DLL load errors (on Linux)
29        - fixed di-harmonic triangle LFO implementation (this LFO implementation
30          is only used by very few systems, most pick the int math
31          implementation, which is usually faster)
32        - fixes for audio drivers with varying buffer sizes
33        - experimental support for running LinuxSampler as a DSSI, LV2 and
34          VST plugin
35        - notification events for stream/voice count statistics are now sent
36          only when there are actual changes
37        - added memory ordering constraints to improve stability on
38          multi-core and multi-cpu systems
39        - maximum voices and disk streams can now be altered at runtime
40        - fixed CPU feature detection on x86_64 (maybe fixes #108)
41        - automatic stacktrace mechanism is now turned off by default and can
42          be switched on by command line option "--stacktrace" (the automatic
43          stacktrace mechanism seems to be broken on most systems at the moment)
44        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
45          a pointer to the launched InstrumentEditor object
46        - added optional 3rd party user data parameter for following
47          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
48          InstrumentEditor::Launch(),
49          InstrumentManager::LaunchInstrumentEditor()
50        - theoretical fix: made SynchronizedConfig follow C++0x memory
51          model more strictly
52    
53      * audio driver:
54        - removed the nonsense audio channel constraint (which was hard coded to
55          max. 100 audio channels) for most audio drivers
56        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
57          opposed to the LSCP specs
58        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
59          reflected the wrong value
60        - fixed a memory management bug in ASIO driver
61        - Makefile fix: JACK_CFLAGS wasn't used
62        - JACK: use jack_client_open instead of the deprecated
63          jack_client_new
64        - added (experimental) CoreAudio driver
65        - applied old fixes to the ASIO driver that were included in the
66          previous binary release but accidentally never committed to CVS
67          (fixes #117)
68    
69      * MIDI driver:
70        - added JACK MIDI driver
71        - dispatch bank select as ordinary CC as well, the user might seriously
72          want to (mis)use it for some purpose ("fixed" in all current MIDI
73          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
74        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, Mme,
75          CoreMidi or AU
76    
77      * instruments database:
78        - avoid time consuming samples scanning when adding instruments
79          to the instruments database
80        - added support for handling lost files in the instruments database
81        - Implemented option for adding instruments in separate directories
82          in the instruments database
83          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
84    
85      * Gigasampler format engine:
86        - fixed a memory leak that could happen when a channel was deleted
87          while notes were playing
88        - made it possible to load an instrument even if the audio thread
89          isn't running
90        - added partial support for the "Controller Triggered" MIDI rule,
91          enough for piano gigs with pedal noise samples
92        - minor fix: only mark FX sends as being modified if really the
93          respective FX send MIDI controller was used
94        - added support for GM global device volume SysEx message
95          (can be selected at compile time to either apply globally to the
96          whole sampler [default] or only to the sampler channels that are
97          connected to the respective MIDI input port the SysEx message arrived
98          on)
99        - bugfix: notes triggered at position 0 in the audio buffer were
100          sometimes wrongly killed in the same buffer, causing no sound to
101          be played
102        - added support for chromatic / drumkit mode Roland GS Sysex message
103          which is usally used to switch a part between chromatic sounds and
104          drumkit sounds (as opposed to their common default setting of MIDI
105          part 10 being a drumkit part and all other ones chromatic parts), in
106          LS however one can switch between the first 16 MIDI instrument maps
107          defined for the sampler
108        - made it possible to create multiple sample channels even if the
109          audio thread isn't running
110        - fixed crash when removing channel with active voices (#116)
111        - bugfix: on sample reference changes (instrument editor), only
112          un-cache the respective sample if it's really not used by any
113          sampler engine anymore
114        - re-cache samples in case they were changed by an instrument editor,
115          e.g. when a sample was added while playing (#82)
116        - fixed hanging notes which occured when note-off event had the exact
117          same time stamp as the voice's note-on event and occured both in the
118          same audio fragment cycle (fixes bug #112)
119        - added support for the "fine tune" and "pitch bend range"
120          instrument-level gig parameters
121        - fixed minor artifacts in pitch bend handling
122        - added support for GS Reset SysEx message
123        - allow gig files to use unlimited downward pitch shifting
124        - added a limit check for upward pitch shifting
125    
126      * LSCP server:
127        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
128          react on MIDI data arriving on certain sampler channels (so far only
129          Note-On and Note-Off events are sent via this LSCP event)
130        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
131          react on MIDI data arriving on certain MIDI input devices (so far only
132          Note-On and Note-Off events are sent via this LSCP event)
133        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
134          SET DB_INSTRUMENT FILE_PATH
135        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
136          frontends to send MIDI messages to specific sampler channel
137        - added two additional fields to GET FILE INSTRUMENT INFO command -
138          KEY_BINDINGS and KEYSWITCH_BINDINGS
139        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
140          was incorrect
141        - Optimized the retrieval of the MIDI instrument mappings
142        - added new LSCP command "SET VOICES" to globally alter the maximum
143          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
144          be triggered respectively
145        - added new LSCP command "SET STREAMS" to globally alter the maximum
146          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
147          which will be triggered respectively
148        - bugfix: retry if "select" returns EINTR (this fixes a crash when
149          a gigedit file dialog is opened)
150        - close all connections when LSCPServer is deleted
151        - hard close of all sockets on exit
152    
153      * Bug fixes:
154        - fixed a crash which occurs when removing a sampler channel waiting
155          to start instrument loading after another channel
156        - fixed a crash which occurs when removing a sampler channel with
157          instrument loading in progress (bug #113)
158        - fixed termination caused by uncaught exception when adding MIDI
159          instrument with PERSISTENT load mode
160        - fixed possible iterator invalidations when resetting the sampler
161        - fixed memory leaks when issuing the following LSCP commands:
162          GET AUDIO_OUTPUT_DRIVER INFO
163          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
164          GET MIDI_INPUT_DRIVER INFO
165          GET MIDI_INPUT_DRIVER_PARAMETER INFO
166        - fixed possible compilation error when sqlite is not present
167        - fixed orphaned pointers when setting maximum voices limit (bug #118)
168        - fixed crash when changing the audio output device of a sampler
169          channel with loaded instrument and start playing notes
170        - fixed endless loop in Engine::SuspendAll() (bug #120)
171        - fixed a low-level atomic load function that was broken on 64-bit
172          PowerPC, which probably could cause crashes on that platform
