3      * 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)

17        (fixes bug #70, patch by Ronald Baljeu)        (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        - automatic stacktrace mechanism is now turned off by default and can
41          be switched on by command line option "--stacktrace" (the automatic
42          stacktrace mechanism seems to be broken on most systems at the moment)
43    
44    * audio driver:    * audio driver:
45      - removed the nonsense audio channel constraint (which was hard coded to      - removed the nonsense audio channel constraint (which was hard coded to
46        max. 100 audio channels) for most audio drivers        max. 100 audio channels) for most audio drivers
47        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
48          opposed to the LSCP specs
49        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
50          reflected the wrong value
51        - fixed a memory management bug in ASIO driver
52        - Makefile fix: JACK_CFLAGS wasn't used
53        - JACK: use jack_client_open instead of the deprecated
54          jack_client_new
55        - added (experimental) CoreAudio driver
56    
57      * MIDI driver:
58        - added JACK MIDI driver
59        - dispatch bank select as ordinary CC as well, the user might seriously
60          want to (mis)use it for some purpose ("fixed" in all current MIDI
61          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
62    
63      * instruments database:
64        - avoid time consuming samples scanning when adding instruments
65          to the instruments database
66        - added support for handling lost files in the instruments database
67        - Implemented option for adding instruments in separate directories
68          in the instruments database
69          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
70    
71      * Gigasampler format engine:
72        - fixed a memory leak that could happen when a channel was deleted
73          while notes were playing
74        - made it possible to load an instrument even if the audio thread
75          isn't running
76        - added partial support for the "Controller Triggered" MIDI rule,
77          enough for piano gigs with pedal noise samples
78        - minor fix: only mark FX sends as being modified if really the
79          respective FX send MIDI controller was used
80        - added support for GM global device volume SysEx message
81          (can be selected at compile time to either apply globally to the
82          whole sampler [default] or only to the sampler channels that are
83          connected to the respective MIDI input port the SysEx message arrived
84          on)
85        - bugfix: notes triggered at position 0 in the audio buffer were
86          sometimes wrongly killed in the same buffer, causing no sound to
87          be played
88        - added support for chromatic / drumkit mode Roland GS Sysex message
89          which is usally used to switch a part between chromatic sounds and
90          drumkit sounds (as opposed to their common default setting of MIDI
91          part 10 being a drumkit part and all other ones chromatic parts), in
92          LS however one can switch between the first 16 MIDI instrument maps
93          defined for the sampler
94        - made it possible to create multiple sample channels even if the
95          audio thread isn't running
96    
97      * LSCP server:
98        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
99          react on MIDI data arriving on certain sampler channels (so far only
100          Note-On and Note-Off events are sent via this LSCP event)
101        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
102          react on MIDI data arriving on certain MIDI input devices (so far only
103          Note-On and Note-Off events are sent via this LSCP event)
104        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
105          SET DB_INSTRUMENT FILE_PATH
106        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
107          frontends to send MIDI messages to specific sampler channel
108        - added two additional fields to GET FILE INSTRUMENT INFO command -
109          KEY_BINDINGS and KEYSWITCH_BINDINGS
110        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
111          was incorrect
112        - Optimized the retrieval of the MIDI instrument mappings
113        - added new LSCP command "SET VOICES" to globally alter the maximum
114          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
115          be triggered respectively
116        - added new LSCP command "SET STREAMS" to globally alter the maximum
117          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
118          which will be triggered respectively
119        - bugfix: retry if "select" returns EINTR (this fixes a crash when
120          a gigedit file dialog is opened)
121    
122      * Bug fixes:
123        - fixed a crash which occurs when removing a sampler channel waiting
124          to start instrument loading after another channel
125        - fixed a crash which occurs when removing a sampler channel with
126          instrument loading in progress (bug #113)
127        - fixed termination caused by uncaught exception when adding MIDI
128          instrument with PERSISTENT load mode
