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    
19      * audio driver:
20        - removed the nonsense audio channel constraint (which was hard coded to
21          max. 100 audio channels) for most audio drivers
22        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
23          opposed to the LSCP specs
24        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
25          reflected the wrong value
26        - fixed a memory management bug in ASIO driver
27    
28      * instruments database:
29        - avoid time consuming samples scanning when adding instruments
30          to the instruments database
31    
32      * Gigasampler format engine:
33        - fixed a memory leak that could happen when a channel was deleted
34          while notes were playing
35        - made it possible to load an instrument even if the audio thread
36          isn't running
37    
38    Version 0.5.1 (6 December 2007)
39    
40      * packaging changes:
41        - added autoconf checks for pthread library
42        - added autoconf check for pthread bug found on certain NPTL-enabled
43          glibc versions (see Gentoo bug report #194076)
44        - added autoconf checks for MS Windows
45    
46      * general changes:
47        - bugfix: the thread used by an editor plugin didn't die when the
48          editor closed
49        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
50          out all the space. operator--() did not apply size_mask after
51          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
52          order to avoid problems with the _NonVolatileReader functions.
53        - bugfix: Stream.h: added a missing divide by BytesPerSample in
54          GetWriteSpace(). Since this function is currently only used in
55          the stream's qsort() compare function, it didn't trigger any
56          bugs.
57        - Resampler.h, Synthesizer.h: cubic interpolation now works in
58          24bit mode too. Faster method to read 24bit words on little
59          endian machines (x86): replaced 3 byte reads + shifts with a 1
60          unaligned 32bit read and shift
61        - experimental support for MS Windows (MIDI input via MME, AUDIO
62          output via ASIO)
63        - made handling of SIGINT signal (Ctrl-C) a bit more robust
64        - support for monitoring the total number of active disk streams
65          (new LSCP commands: GET TOTAL_STREAM_COUNT,
66          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
67    
68      * AUDIO driver:
69        - added Windows ASIO low latency audio driver
70    
71      * MIDI driver:
72        - added MME Windows MIDI driver
73    
74      * LSCP server:
75        - added support for Windows style path / filenames, however with
76          forward slash path separators instead of backslash
77          (i.e. "C:/foo/bar.gig")
78        - allow naughty liblscp to send non-string device parameters within
79          apostrophes as well
80        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
81          "LIST FILE INSTRUMENTS <file>" and
82          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
83          about an arbitrary instrument file on the system where the sampler is
84          running on
85    
86    Version 0.5.0 (15 October 2007)

99        - global.h now only covers global definitions that are needed for the

146        - added experimental code for synchronizing instrument editors hosted

159        - reenabled assembly features support, at the moment only for
160          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
161        - minor assembly fix in x86 features detection (don't use the PIC
162          register, to avoid relocations in the text segment at runtime)

199          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
200        - parser now supports extended ASCII character set
201          (up to ASCII code 255, i.e. includes now umlauts and accents)
202        - filename arguments in LSCP commands now allow to use escape
203          sequences, that is directly literal as one of: \', \", \\, \n, \r,
204          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
205          code value like \xf2) (fixes bug #24)
206        - the following LSCP commands now also support escape sequences for at
207          least one of their text-based parameters (i.e. name, description):

215          occured, the unexpected character and the actually expected, possible
216          character(s), the latter only if less than 5 possibilities)
217        - made sure that LSCP syntax is not affected by gigedit locale
218          settings
219        - bugfix regarding strings parameter lists: all comma separated lists
220          of strings were treated as being one string containing commas

229        - fixed a crash which occurs when changing the number of ports of a MIDI
230          device connected to a sampler channel to number less then or equal
231          to the index of the port to which the sampler channel is connected.
232        - The previous bindings were not been disconnected when altering
233          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
234          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
235        - The active stream/voice count statistic was incorrect.
236        - notification events were not been sent for some sampler
