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    
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    
122    
123    Version 0.5.1 (6 December 2007)
124    
125      * packaging changes:
126        - added autoconf checks for pthread library
127        - added autoconf check for pthread bug found on certain NPTL-enabled
128          glibc versions (see Gentoo bug report #194076)
129        - added autoconf checks for MS Windows
130    
131      * general changes:
132        - bugfix: the thread used by an editor plugin didn't die when the
133          editor closed
134        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
135          out all the space. operator--() did not apply size_mask after
136          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
137          order to avoid problems with the _NonVolatileReader functions.
138        - bugfix: Stream.h: added a missing divide by BytesPerSample in
139          GetWriteSpace(). Since this function is currently only used in
140          the stream's qsort() compare function, it didn't trigger any
141          bugs.
142        - Resampler.h, Synthesizer.h: cubic interpolation now works in
143          24bit mode too. Faster method to read 24bit words on little
144          endian machines (x86): replaced 3 byte reads + shifts with a 1
145          unaligned 32bit read and shift
146        - experimental support for MS Windows (MIDI input via MME, AUDIO
147          output via ASIO)
148        - made handling of SIGINT signal (Ctrl-C) a bit more robust
149        - support for monitoring the total number of active disk streams
150          (new LSCP commands: GET TOTAL_STREAM_COUNT,
151          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
152    
153      * AUDIO driver:
154        - added Windows ASIO low latency audio driver
155    
156      * MIDI driver:
157        - added MME Windows MIDI driver
158    
159      * LSCP server:
160        - added support for Windows style path / filenames, however with
161          forward slash path separators instead of backslash
162          (i.e. "C:/foo/bar.gig")
163        - allow naughty liblscp to send non-string device parameters within
164          apostrophes as well
165        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
166          "LIST FILE INSTRUMENTS <file>" and
167          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
168          about an arbitrary instrument file on the system where the sampler is
169          running on
170
