1  Version CVS HEAD (?)  Version CVS HEAD (?)
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    
9      * general changes:
10        - bugfix: on some POSIX systems instrument editor plugins refused to
11          load as we used a non-portable Linux specific struct field
12          (fixes bug #70, patch by Ronald Baljeu)
13        - fixed endless loop which occured when loading an instrument editor
14          plugin DLL on Windows systems failed
15        - fixed memory leaks that occurred when liblinuxsampler was unloaded
16        - optimized the SynchronizedConfig class so it doesn't wait
17          unnecessarily long after an update
18        - added support for notifying instrument editors on note-on / note-off
19          events (e.g. to highlight the pressed keys on the virtual keyboard
20          of gigedit)
21        - added support for triggering notes by instrument editors (see above)
22        - be verbose on DLL load errors (on Linux)
23        - fixed di-harmonic triangle LFO implementation (this LFO implementation
24          is only used by very few systems, most pick the int math
25          implementation, which is usually faster)
26    
27      * audio driver:
28        - removed the nonsense audio channel constraint (which was hard coded to
29          max. 100 audio channels) for most audio drivers
30        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
31          opposed to the LSCP specs
32        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
33          reflected the wrong value
34        - fixed a memory management bug in ASIO driver
35    
36      * MIDI driver:
37        - added JACK MIDI driver
38    
39      * instruments database:
40        - avoid time consuming samples scanning when adding instruments
41          to the instruments database
42    
43      * Gigasampler format engine:
44        - fixed a memory leak that could happen when a channel was deleted
45          while notes were playing
46        - made it possible to load an instrument even if the audio thread
47          isn't running
48        - added partial support for the "Controller Triggered" MIDI rule,
49          enough for piano gigs with pedal noise samples
50    
51      * LSCP server:
52        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
53          react on MIDI data arriving on certain sampler channels (so far only
54          Note-On and Note-Off events are sent via this LSCP event)
55        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
56          react on MIDI data arriving on certain MIDI input devices (so far only
57          Note-On and Note-Off events are sent via this LSCP event)
58    
59    Version 0.5.1 (6 December 2007)
60    
61      * packaging changes:
62        - added autoconf checks for pthread library
63        - added autoconf check for pthread bug found on certain NPTL-enabled
64          glibc versions (see Gentoo bug report #194076)
65        - added autoconf checks for MS Windows
66    
67      * general changes:
68        - bugfix: the thread used by an editor plugin didn't die when the
69          editor closed
70        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
71          out all the space. operator--() did not apply size_mask after
72          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
73          order to avoid problems with the _NonVolatileReader functions.
74        - bugfix: Stream.h: added a missing divide by BytesPerSample in
75          GetWriteSpace(). Since this function is currently only used in
76          the stream's qsort() compare function, it didn't trigger any
77          bugs.
78        - Resampler.h, Synthesizer.h: cubic interpolation now works in
79          24bit mode too. Faster method to read 24bit words on little
80          endian machines (x86): replaced 3 byte reads + shifts with a 1
81          unaligned 32bit read and shift
82        - experimental support for MS Windows (MIDI input via MME, AUDIO
83          output via ASIO)
84        - made handling of SIGINT signal (Ctrl-C) a bit more robust
85        - support for monitoring the total number of active disk streams
86          (new LSCP commands: GET TOTAL_STREAM_COUNT,
87          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
88    
89      * AUDIO driver:
90        - added Windows ASIO low latency audio driver
91    
92      * MIDI driver:
93        - added MME Windows MIDI driver
94    
95      * LSCP server:
96        - added support for Windows style path / filenames, however with
97          forward slash path separators instead of backslash
98          (i.e. "C:/foo/bar.gig")
99        - allow naughty liblscp to send non-string device parameters within
100          apostrophes as well
101        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
102          "LIST FILE INSTRUMENTS <file>" and
103          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
104          about an arbitrary instrument file on the system where the sampler is
105          running on
106    
107    Version 0.5.0 (15 October 2007)
