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    
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    
36    Version 0.5.1 (6 December 2007)
37    
38      * packaging changes:
39        - added autoconf checks for pthread library
40        - added autoconf check for pthread bug found on certain NPTL-enabled
41          glibc versions (see Gentoo bug report #194076)
42        - added autoconf checks for MS Windows
43    
44      * general changes:
45        - bugfix: the thread used by an editor plugin didn't die when the
46          editor closed
47        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
48          out all the space. operator--() did not apply size_mask after
49          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
50          order to avoid problems with the _NonVolatileReader functions.
51        - bugfix: Stream.h: added a missing divide by BytesPerSample in
52          GetWriteSpace(). Since this function is currently only used in
53          the stream's qsort() compare function, it didn't trigger any
54          bugs.
55        - Resampler.h, Synthesizer.h: cubic interpolation now works in
56          24bit mode too. Faster method to read 24bit words on little
57          endian machines (x86): replaced 3 byte reads + shifts with a 1
58          unaligned 32bit read and shift
59        - experimental support for MS Windows (MIDI input via MME, AUDIO
60          output via ASIO)
61        - made handling of SIGINT signal (Ctrl-C) a bit more robust
62        - support for monitoring the total number of active disk streams
63          (new LSCP commands: GET TOTAL_STREAM_COUNT,
64          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
65    
66      * AUDIO driver:
67        - added Windows ASIO low latency audio driver
68    
69      * MIDI driver:
70        - added MME Windows MIDI driver
71    
72      * LSCP server:
73        - added support for Windows style path / filenames, however with
74          forward slash path separators instead of backslash
75          (i.e. "C:/foo/bar.gig")
76        - allow naughty liblscp to send non-string device parameters within
77          apostrophes as well
78        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
79          "LIST FILE INSTRUMENTS <file>" and
80          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
81          about an arbitrary instrument file on the system where the sampler is
82          running on
83    
84    Version 0.5.0 (15 October 2007)
85    
86      * packaging changes:
87        - config.h is not going to be installed along with liblinuxsampler's
88          API header files anymore
89      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to
90        the Doxygen API documentation (explicitly listed in Doxyfile.in)        the Doxygen API documentation (explicitly listed in Doxyfile.in)
91        - added completely new XCode project files for Mac OSX which is now
92          capable to execute our autoconf environment, thus no need anymore
93          to maintain the compile time configuration file (osx/version.h) for
94          OSX manually (patch by Toshi Nagata)
95        - fixed buggy boolean --enable-foo / --disable-foo configure script
96          parameters
97        - global.h now only covers global definitions that are needed for the
98          C++ API header files, all implementation internal global definitions
99          are now in global_private.h
100        - atomic.h is not exposed to the C++ API anymore
101        - no need to include config.h anymore for using LS's API header files
102        - fixed warnings in API doc generation
103

131      - Implemented new, improved notification system      - Implemented new, improved notification system
132      - fixed compilation errors regarding OSX      - fixed compilation errors regarding OSX
133        (patch by Toshi Nagata)        (patch by Toshi Nagata)
134        - implemented instruments database
135        - added support for escape sequences to the instruments database
136        - added highly experimental support for on-the-fly instrument editing
137          within the sampler's process (by using instrument editor plugins),
138          you'll notice the new "Registered instrument editors:" message on
139          startup, added a new LSCP command:
140          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
141          to spawn a matching instrument editor for the instrument on the
142          given sampler channel, the plugin path can be overridden at compile
143          time with ./configure --enable-plugin-dir=/some/dir
144        - added experimental code for synchronizing instrument editors hosted
145          in the sampler's process to safely edit instruments while playing
146          without a crash (hopefully) by either suspending single regions
147          wherever possible or if unavoidable whole engine(s)
148        - fixed several issues in fundamental "Thread" class: set scheduling
149          policy and priority on thread level, set a minimum stack size for
150          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
151          threads simply inherited properties of starting thread instead of
152          setting their own policy and priority
153        - minor fix in our automatic stack trace mechanism on crashes, the
154          main process did not wait for the stack trace process to finish
155          its output
156        - fixed some minor memory leaks
157        - reenabled assembly features support, at the moment only for
158          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
159        - minor assembly fix in x86 features detection (don't use the PIC
160          register, to avoid relocations in the text segment at runtime)
161        - POSIX callback functions of Thread.h are hidden
162    
163    * MIDI driver:    * MIDI driver:
164      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages

186      - minor fix of EGDecay (patch by Toshi Nagata)      - minor fix of EGDecay (patch by Toshi Nagata)
187        - fixed compiler error when --enable-override-filter-type was
188          supplied to the configure script (fixes #46)
189        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
190          instead of a fix value
191        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
192          127 (solo mode) only kill voices if the respective mode really
193          changed
194    
195      * LSCP server:
196        - fixed compile time error for old Bison versions
197          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
198        - parser now supports extended ASCII character set
199          (up to ASCII code 255, i.e. includes now umlauts and accents)
200        - filename arguments in LSCP commands now allow to use escape
201          sequences, that is directly literal as one of: \', \", \\, \n, \r,
202          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
203          code value like \xf2) (fixes bug #24)
204        - the following LSCP commands now also support escape sequences for at
205          least one of their text-based parameters (i.e. name, description):
206          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
207          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
208          "SET DB_INSTRUMENT_DIRECTORY NAME",
209          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
210          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
211          "FIND DB_INSTRUMENT_DIRECTORIES"
212        - returns verbose syntax errors (line and column where syntax error
213          occured, the unexpected character and the actually expected, possible
214          character(s), the latter only if less than 5 possibilities)
215        - made sure that LSCP syntax is not affected by gigedit locale
216          settings
217        - bugfix regarding strings parameter lists: all comma separated lists
218          of strings were treated as being one string containing commas
219          (fixes #57)
220    
221    * Bug fixes:    * Bug fixes:
222      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
223      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
224        channel audio output device"        channel audio output device"
225        - fixed a crash which occurs when reassigning the same engine
226          on a sampler channel with connected MIDI device
227        - fixed a crash which occurs when changing the number of ports of a MIDI
228          device connected to a sampler channel to number less then or equal
229          to the index of the port to which the sampler channel is connected.
230        - The previous bindings were not been disconnected when altering
231          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
232          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
233        - The active stream/voice count statistic was incorrect.
234        - notification events were not been sent for some sampler
235          channel changes
236        - added default min and max values to restrict the number of allowed
237          audio output channels and MIDI input ports
238        - the connection to the PCM interface is now closed when destroying
239          an audio output device
240        - files with slash in their path or filename could not be loaded
241
