2    
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    
45      * audio driver:
46        - removed the nonsense audio channel constraint (which was hard coded to
47          max. 100 audio channels) for most audio drivers
48        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
49          opposed to the LSCP specs
50        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
51          reflected the wrong value
52        - fixed a memory management bug in ASIO driver
53        - Makefile fix: JACK_CFLAGS wasn't used
54        - JACK: use jack_client_open instead of the deprecated
55          jack_client_new
56        - added (experimental) CoreAudio driver
57    
58      * MIDI driver:
59        - added JACK MIDI driver
60        - dispatch bank select as ordinary CC as well, the user might seriously
61          want to (mis)use it for some purpose ("fixed" in all current MIDI
62          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
63    
64      * instruments database:
65        - avoid time consuming samples scanning when adding instruments
66          to the instruments database
67        - added support for handling lost files in the instruments database
68        - Implemented option for adding instruments in separate directories
69          in the instruments database
70          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
71    
72      * Gigasampler format engine:
73        - fixed a memory leak that could happen when a channel was deleted
74          while notes were playing
75        - made it possible to load an instrument even if the audio thread
76          isn't running
77        - added partial support for the "Controller Triggered" MIDI rule,
78          enough for piano gigs with pedal noise samples
79        - minor fix: only mark FX sends as being modified if really the
80          respective FX send MIDI controller was used
81        - added support for GM global device volume SysEx message
82          (can be selected at compile time to either apply globally to the
83          whole sampler [default] or only to the sampler channels that are
84          connected to the respective MIDI input port the SysEx message arrived
85          on)
86        - bugfix: notes triggered at position 0 in the audio buffer were
87          sometimes wrongly killed in the same buffer, causing no sound to
88          be played
89        - added support for chromatic / drumkit mode Roland GS Sysex message
90          which is usally used to switch a part between chromatic sounds and
91          drumkit sounds (as opposed to their common default setting of MIDI
92          part 10 being a drumkit part and all other ones chromatic parts), in
93          LS however one can switch between the first 16 MIDI instrument maps
94          defined for the sampler
95        - made it possible to create multiple sample channels even if the
96          audio thread isn't running
97        - fixed crash when removing channel with active voices (#116)
98    
99      * LSCP server:
100        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
101          react on MIDI data arriving on certain sampler channels (so far only
102          Note-On and Note-Off events are sent via this LSCP event)
103        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
104          react on MIDI data arriving on certain MIDI input devices (so far only
105          Note-On and Note-Off events are sent via this LSCP event)
106        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
107          SET DB_INSTRUMENT FILE_PATH
108        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
109          frontends to send MIDI messages to specific sampler channel
110        - added two additional fields to GET FILE INSTRUMENT INFO command -
111          KEY_BINDINGS and KEYSWITCH_BINDINGS
112        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
113          was incorrect
114        - Optimized the retrieval of the MIDI instrument mappings
115        - added new LSCP command "SET VOICES" to globally alter the maximum
116          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
117          be triggered respectively
118        - added new LSCP command "SET STREAMS" to globally alter the maximum
119          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
120          which will be triggered respectively
121        - bugfix: retry if "select" returns EINTR (this fixes a crash when
122          a gigedit file dialog is opened)
123    
124      * Bug fixes:
125        - fixed a crash which occurs when removing a sampler channel waiting
126          to start instrument loading after another channel
127        - fixed a crash which occurs when removing a sampler channel with
128          instrument loading in progress (bug #113)
129        - fixed termination caused by uncaught exception when adding MIDI
130          instrument with PERSISTENT load mode
131        - fixed possible iterator invalidations when resetting the sampler
132        - fixed memory leaks when issuing the following LSCP commands:
133          GET AUDIO_OUTPUT_DRIVER INFO
134          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
135          GET MIDI_INPUT_DRIVER INFO
136          GET MIDI_INPUT_DRIVER_PARAMETER INFO
137        - fixed possible compilation error when sqlite is not present
138        - fixed orphaned pointers when setting maximum voices limit (bug #118)
139    
140    
141    Version 0.5.1 (6 December 2007)
142    
143      * packaging changes:
144        - added autoconf checks for pthread library
145        - added autoconf check for pthread bug found on certain NPTL-enabled
146          glibc versions (see Gentoo bug report #194076)
147        - added autoconf checks for MS Windows
148    
149      * general changes:
150        - bugfix: the thread used by an editor plugin didn't die when the
151          editor closed
152        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
153          out all the space. operator--() did not apply size_mask after
154          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
155          order to avoid problems with the _NonVolatileReader functions.
156        - bugfix: Stream.h: added a missing divide by BytesPerSample in
157          GetWriteSpace(). Since this function is currently only used in
158          the stream's qsort() compare function, it didn't trigger any
159          bugs.
160        - Resampler.h, Synthesizer.h: cubic interpolation now works in
161          24bit mode too. Faster method to read 24bit words on little
162          endian machines (x86): replaced 3 byte reads + shifts with a 1
163          unaligned 32bit read and shift
164        - experimental support for MS Windows (MIDI input via MME, AUDIO
165          output via ASIO)
166        - made handling of SIGINT signal (Ctrl-C) a bit more robust
167        - support for monitoring the total number of active disk streams
168          (new LSCP commands: GET TOTAL_STREAM_COUNT,
169          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
170    
171      * AUDIO driver:
172        - added Windows ASIO low latency audio driver
173    
174      * MIDI driver:
175        - added MME Windows MIDI driver
176    
177      * LSCP server:
178        - added support for Windows style path / filenames, however with
179          forward slash path separators instead of backslash
180          (i.e. "C:/foo/bar.gig")
181        - allow naughty liblscp to send non-string device parameters within
182          apostrophes as well
183        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
184          "LIST FILE INSTRUMENTS <file>" and
185          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
186          about an arbitrary instrument file on the system where the sampler is
187          running on
