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    
53      * MIDI driver:
54        - added JACK MIDI driver
55        - dispatch bank select as ordinary CC as well, the user might seriously
56          want to (mis)use it for some purpose ("fixed" in all current MIDI
57          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
58    
59      * instruments database:
60        - avoid time consuming samples scanning when adding instruments
61          to the instruments database
62        - added support for handling lost files in the instruments database
63        - Implemented option for adding instruments in separate directories
64          in the instruments database
65          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
66    
67      * Gigasampler format engine:
68        - fixed a memory leak that could happen when a channel was deleted
69          while notes were playing
70        - made it possible to load an instrument even if the audio thread
71          isn't running
72        - added partial support for the "Controller Triggered" MIDI rule,
73          enough for piano gigs with pedal noise samples
74        - minor fix: only mark FX sends as being modified if really the
75          respective FX send MIDI controller was used
76        - added support for GM global device volume SysEx message
77          (can be selected at compile time to either apply globally to the
78          whole sampler [default] or only to the sampler channels that are
79          connected to the respective MIDI input port the SysEx message arrived
80          on)
81        - bugfix: notes triggered at position 0 in the audio buffer were
82          sometimes wrongly killed in the same buffer, causing no sound to
83          be played
84        - added support for chromatic / drumkit mode Roland GS Sysex message
85          which is usally used to switch a part between chromatic sounds and
86          drumkit sounds (as opposed to their common default setting of MIDI
87          part 10 being a drumkit part and all other ones chromatic parts), in
88          LS however one can switch between the first 16 MIDI instrument maps
89          defined for the sampler
90        - made it possible to create multiple sample channels even if the
91          audio thread isn't running
92    
93      * LSCP server:
94        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
95          react on MIDI data arriving on certain sampler channels (so far only
96          Note-On and Note-Off events are sent via this LSCP event)
97        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
98          react on MIDI data arriving on certain MIDI input devices (so far only
99          Note-On and Note-Off events are sent via this LSCP event)
100        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
101          SET DB_INSTRUMENT FILE_PATH
102        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
103          frontends to send MIDI messages to specific sampler channel
104        - added two additional fields to GET FILE INSTRUMENT INFO command -
105          KEY_BINDINGS and KEYSWITCH_BINDINGS
106        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
107          was incorrect
108        - Optimized the retrieval of the MIDI instrument mappings
109        - added new LSCP command "SET VOICES" to globally alter the maximum
110          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
111          be triggered respectively
112        - added new LSCP command "SET STREAMS" to globally alter the maximum
113          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
114          which will be triggered respectively
115        - bugfix: retry if "select" returns EINTR (this fixes a crash when
116          a gigedit file dialog is opened)
117    
118      * Bug fixes:
119        - fixed a crash which occurs when removing a sampler channel waiting
120          to start instrument loading after another channel
121        - fixed a crash which occurs when removing a sampler channel with
122          instrument loading in progress (bug #113)
123        - fixed termination caused by uncaught exception when adding MIDI
124          instrument with PERSISTENT load mode
125    
126    
127    Version 0.5.1 (6 December 2007)
128    
129      * packaging changes:
130      - added autoconf checks for pthread library      - added autoconf checks for pthread library
131      - added autoconf check for pthread bug found on certain NPTL-enabled      - added autoconf check for pthread bug found on certain NPTL-enabled
132        glibc versions (see Gentoo bug report #194076)        glibc versions (see Gentoo bug report #194076)
133        - added autoconf checks for MS Windows
134    
135      * general changes:
136        - bugfix: the thread used by an editor plugin didn't die when the
137          editor closed
138        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
139          out all the space. operator--() did not apply size_mask after
140          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
141          order to avoid problems with the _NonVolatileReader functions.
142        - bugfix: Stream.h: added a missing divide by BytesPerSample in
143          GetWriteSpace(). Since this function is currently only used in
144          the stream's qsort() compare function, it didn't trigger any
145          bugs.
146        - Resampler.h, Synthesizer.h: cubic interpolation now works in
147          24bit mode too. Faster method to read 24bit words on little
148          endian machines (x86): replaced 3 byte reads + shifts with a 1
149          unaligned 32bit read and shift
150        - experimental support for MS Windows (MIDI input via MME, AUDIO
151          output via ASIO)
152        - made handling of SIGINT signal (Ctrl-C) a bit more robust
153        - support for monitoring the total number of active disk streams
154          (new LSCP commands: GET TOTAL_STREAM_COUNT,
155          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
156    
157      * AUDIO driver:
158        - added Windows ASIO low latency audio driver
159    
160      * MIDI driver:
161        - added MME Windows MIDI driver
162    
163      * LSCP server:
164        - added support for Windows style path / filenames, however with
165          forward slash path separators instead of backslash
166          (i.e. "C:/foo/bar.gig")
167        - allow naughty liblscp to send non-string device parameters within
168          apostrophes as well
169        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
170          "LIST FILE INSTRUMENTS <file>" and
171          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
172          about an arbitrary instrument file on the system where the sampler is
173          running on
174    
175  Version 0.5.0 (15 October 2007)  Version 0.5.0 (15 October 2007)
