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    
10      * general changes:
11        - bugfix: on some POSIX systems instrument editor plugins refused to
12          load as we used a non-portable Linux specific struct field
13          (fixes bug #70, patch by Ronald Baljeu)
14        - fixed endless loop which occured when loading an instrument editor
15          plugin DLL on Windows systems failed
16        - fixed memory leaks that occurred when liblinuxsampler was unloaded
17        - optimized the SynchronizedConfig class so it doesn't wait
18          unnecessarily long after an update
19        - added support for notifying instrument editors on note-on / note-off
20          events (e.g. to highlight the pressed keys on the virtual keyboard
21          of gigedit)
22        - added support for triggering notes by instrument editors (see above)
23        - be verbose on DLL load errors (on Linux)
24        - fixed di-harmonic triangle LFO implementation (this LFO implementation
25          is only used by very few systems, most pick the int math
26          implementation, which is usually faster)
27    
28      * audio driver:
29        - removed the nonsense audio channel constraint (which was hard coded to
30          max. 100 audio channels) for most audio drivers
31        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
32          opposed to the LSCP specs
33        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
34          reflected the wrong value
35        - fixed a memory management bug in ASIO driver
36    
37      * MIDI driver:
38        - added JACK MIDI driver
39        - dispatch bank select as ordinary CC as well, the user might seriously
40          want to (mis)use it for some purpose ("fixed" in all current MIDI
41          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
42    
43      * instruments database:
44        - avoid time consuming samples scanning when adding instruments
45          to the instruments database
46    
47      * Gigasampler format engine:
48        - fixed a memory leak that could happen when a channel was deleted
49          while notes were playing
50        - made it possible to load an instrument even if the audio thread
51          isn't running
52        - added partial support for the "Controller Triggered" MIDI rule,
53          enough for piano gigs with pedal noise samples
54        - minor fix: only mark FX sends as being modified if really the
55          respective FX send MIDI controller was used
56        - added support for GM global device volume SysEx message
57    
58      * LSCP server:
59        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
60          react on MIDI data arriving on certain sampler channels (so far only
61          Note-On and Note-Off events are sent via this LSCP event)
62        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
63          react on MIDI data arriving on certain MIDI input devices (so far only
64          Note-On and Note-Off events are sent via this LSCP event)
65    
66    Version 0.5.1 (6 December 2007)
67    
68      * packaging changes:
69        - added autoconf checks for pthread library
70        - added autoconf check for pthread bug found on certain NPTL-enabled
71          glibc versions (see Gentoo bug report #194076)
72        - added autoconf checks for MS Windows
73    
74      * general changes:
75        - bugfix: the thread used by an editor plugin didn't die when the
76          editor closed
77        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
78          out all the space. operator--() did not apply size_mask after
79          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
80          order to avoid problems with the _NonVolatileReader functions.
81        - bugfix: Stream.h: added a missing divide by BytesPerSample in
82          GetWriteSpace(). Since this function is currently only used in
83          the stream's qsort() compare function, it didn't trigger any
84          bugs.
85        - Resampler.h, Synthesizer.h: cubic interpolation now works in
86          24bit mode too. Faster method to read 24bit words on little
87          endian machines (x86): replaced 3 byte reads + shifts with a 1
88          unaligned 32bit read and shift
89        - experimental support for MS Windows (MIDI input via MME, AUDIO
90          output via ASIO)
91        - made handling of SIGINT signal (Ctrl-C) a bit more robust
92        - support for monitoring the total number of active disk streams
93          (new LSCP commands: GET TOTAL_STREAM_COUNT,
94          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
95    
96      * AUDIO driver:
97        - added Windows ASIO low latency audio driver
98    
99      * MIDI driver:
100        - added MME Windows MIDI driver
101    
102      * LSCP server:
103        - added support for Windows style path / filenames, however with
104          forward slash path separators instead of backslash
105          (i.e. "C:/foo/bar.gig")
106        - allow naughty liblscp to send non-string device parameters within
107          apostrophes as well
108        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
109          "LIST FILE INSTRUMENTS <file>" and
110          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
111          about an arbitrary instrument file on the system where the sampler is
112          running on
113
