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    
14      * general changes:
15        - bugfix: on some POSIX systems instrument editor plugins refused to
16          load as we used a non-portable Linux specific struct field
17          (fixes bug #70, patch by Ronald Baljeu)
18        - fixed endless loop which occured when loading an instrument editor
19          plugin DLL on Windows systems failed
20        - fixed memory leaks that occurred when liblinuxsampler was unloaded
21        - optimized the SynchronizedConfig class so it doesn't wait
22          unnecessarily long after an update
23        - added support for notifying instrument editors on note-on / note-off
24          events (e.g. to highlight the pressed keys on the virtual keyboard
25          of gigedit)
26        - added support for triggering notes by instrument editors (see above)
27        - be verbose on DLL load errors (on Linux)
28        - fixed di-harmonic triangle LFO implementation (this LFO implementation
29          is only used by very few systems, most pick the int math
30          implementation, which is usually faster)
31        - fixes for audio drivers with varying buffer sizes
32        - experimental support for running LinuxSampler as a DSSI, LV2 and
33          VST plugin
34        - notification events for stream/voice count statistics are now sent
35          only when there are actual changes
36        - added memory ordering constraints to improve stability on
37          multi-core and multi-cpu systems
38        - maximum voices and disk streams can now be altered at runtime
39        - fixed CPU feature detection on x86_64 (maybe fixes #108)
40    
41      * audio driver:
42        - removed the nonsense audio channel constraint (which was hard coded to
43          max. 100 audio channels) for most audio drivers
44        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
45          opposed to the LSCP specs
46        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
47          reflected the wrong value
48        - fixed a memory management bug in ASIO driver
49        - Makefile fix: JACK_CFLAGS wasn't used
50        - JACK: use jack_client_open instead of the deprecated
51          jack_client_new
52        - added (experimental) CoreAudio driver
53    
54      * MIDI driver:
55        - added JACK MIDI driver
56        - dispatch bank select as ordinary CC as well, the user might seriously
57          want to (mis)use it for some purpose ("fixed" in all current MIDI
58          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
59    
60      * instruments database:
61        - avoid time consuming samples scanning when adding instruments
62          to the instruments database
63        - added support for handling lost files in the instruments database
64        - Implemented option for adding instruments in separate directories
65          in the instruments database
66          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
67    
68      * Gigasampler format engine:
69        - fixed a memory leak that could happen when a channel was deleted
70          while notes were playing
71        - made it possible to load an instrument even if the audio thread
72          isn't running
73        - added partial support for the "Controller Triggered" MIDI rule,
74          enough for piano gigs with pedal noise samples
75        - minor fix: only mark FX sends as being modified if really the
76          respective FX send MIDI controller was used
77        - added support for GM global device volume SysEx message
78          (can be selected at compile time to either apply globally to the
79          whole sampler [default] or only to the sampler channels that are
80          connected to the respective MIDI input port the SysEx message arrived
81          on)
82        - bugfix: notes triggered at position 0 in the audio buffer were
83          sometimes wrongly killed in the same buffer, causing no sound to
84          be played
85        - added support for chromatic / drumkit mode Roland GS Sysex message
86          which is usally used to switch a part between chromatic sounds and
87          drumkit sounds (as opposed to their common default setting of MIDI
88          part 10 being a drumkit part and all other ones chromatic parts), in
89          LS however one can switch between the first 16 MIDI instrument maps
90          defined for the sampler
91        - made it possible to create multiple sample channels even if the
92          audio thread isn't running
93    
94      * LSCP server:
95        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
96          react on MIDI data arriving on certain sampler channels (so far only
97          Note-On and Note-Off events are sent via this LSCP event)
98        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
99          react on MIDI data arriving on certain MIDI input devices (so far only
100          Note-On and Note-Off events are sent via this LSCP event)
101        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
102          SET DB_INSTRUMENT FILE_PATH
103        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
104          frontends to send MIDI messages to specific sampler channel
105        - added two additional fields to GET FILE INSTRUMENT INFO command -
106          KEY_BINDINGS and KEYSWITCH_BINDINGS
107        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
108          was incorrect
109        - Optimized the retrieval of the MIDI instrument mappings
110        - added new LSCP command "SET VOICES" to globally alter the maximum
111          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
112          be triggered respectively
113        - added new LSCP command "SET STREAMS" to globally alter the maximum
114          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
115          which will be triggered respectively
116        - bugfix: retry if "select" returns EINTR (this fixes a crash when
117          a gigedit file dialog is opened)
118    
119      * Bug fixes:
120        - fixed a crash which occurs when removing a sampler channel waiting
121          to start instrument loading after another channel
122        - fixed a crash which occurs when removing a sampler channel with
123          instrument loading in progress (bug #113)
124        - fixed termination caused by uncaught exception when adding MIDI
125          instrument with PERSISTENT load mode
