1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3      * 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    
16      * audio driver:
17        - removed the nonsense audio channel constraint (which was hard coded to
18          max. 100 audio channels) for most audio drivers
19        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
20          opposed to the LSCP specs
21        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
22          reflected the wrong value
23    
24      * instruments database:
25        - avoid time consuming samples scanning when adding instruments
26          to the instruments database
27    
28    Version 0.5.1 (6 December 2007)
29    
30      * packaging changes:
31        - added autoconf checks for pthread library
32        - added autoconf check for pthread bug found on certain NPTL-enabled
33          glibc versions (see Gentoo bug report #194076)
34        - added autoconf checks for MS Windows
35    
36      * general changes:
37        - bugfix: the thread used by an editor plugin didn't die when the
38          editor closed
39        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
40          out all the space. operator--() did not apply size_mask after
41          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
42          order to avoid problems with the _NonVolatileReader functions.
43        - bugfix: Stream.h: added a missing divide by BytesPerSample in
44          GetWriteSpace(). Since this function is currently only used in
45          the stream's qsort() compare function, it didn't trigger any
46          bugs.
47        - Resampler.h, Synthesizer.h: cubic interpolation now works in
48          24bit mode too. Faster method to read 24bit words on little
49          endian machines (x86): replaced 3 byte reads + shifts with a 1
50          unaligned 32bit read and shift
51        - experimental support for MS Windows (MIDI input via MME, AUDIO
52          output via ASIO)
53        - made handling of SIGINT signal (Ctrl-C) a bit more robust
54        - support for monitoring the total number of active disk streams
55          (new LSCP commands: GET TOTAL_STREAM_COUNT,
56          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
57    
58      * AUDIO driver:
59        - added Windows ASIO low latency audio driver
60    
61      * MIDI driver:
62        - added MME Windows MIDI driver
63    
64      * LSCP server:
65        - added support for Windows style path / filenames, however with
66          forward slash path separators instead of backslash
67          (i.e. "C:/foo/bar.gig")
68        - allow naughty liblscp to send non-string device parameters within
69          apostrophes as well
70        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
71          "LIST FILE INSTRUMENTS <file>" and
72          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
73          about an arbitrary instrument file on the system where the sampler is
74          running on
75    
76    Version 0.5.0 (15 October 2007)
77    
78      * packaging changes:
79        - config.h is not going to be installed along with liblinuxsampler's
80          API header files anymore
81        - only the API relevant header (and source) files will be exported to
82          the Doxygen API documentation (explicitly listed in Doxyfile.in)
83        - added completely new XCode project files for Mac OSX which is now
84          capable to execute our autoconf environment, thus no need anymore
85          to maintain the compile time configuration file (osx/version.h) for
86          OSX manually (patch by Toshi Nagata)
87        - fixed buggy boolean --enable-foo / --disable-foo configure script
88          parameters
89        - global.h now only covers global definitions that are needed for the
90          C++ API header files, all implementation internal global definitions
91          are now in global_private.h
92        - atomic.h is not exposed to the C++ API anymore
93        - no need to include config.h anymore for using LS's API header files
94        - fixed warnings in API doc generation
95    
96    * general changes:    * general changes:

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

175        even if sustain is 100%        even if sustain is 100%
176        - more EG fixes: the level could sometimes go below zero and cause
177          noises or crashes
178        - minor fix of EGDecay (patch by Toshi Nagata)
179        - fixed compiler error when --enable-override-filter-type was
180          supplied to the configure script (fixes #46)
181        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
182          instead of a fix value
183        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
184          127 (solo mode) only kill voices if the respective mode really
185          changed
186    
187      * LSCP server:
188        - fixed compile time error for old Bison versions
189          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
190        - parser now supports extended ASCII character set
191          (up to ASCII code 255, i.e. includes now umlauts and accents)
192        - filename arguments in LSCP commands now allow to use escape
193          sequences, that is directly literal as one of: \', \", \\, \n, \r,
194          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
195          code value like \xf2) (fixes bug #24)
196        - the following LSCP commands now also support escape sequences for at
197          least one of their text-based parameters (i.e. name, description):
198          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
199          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
200          "SET DB_INSTRUMENT_DIRECTORY NAME",
201          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
202          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
203          "FIND DB_INSTRUMENT_DIRECTORIES"
204        - returns verbose syntax errors (line and column where syntax error
205          occured, the unexpected character and the actually expected, possible
206          character(s), the latter only if less than 5 possibilities)
207        - made sure that LSCP syntax is not affected by gigedit locale
208          settings
209        - bugfix regarding strings parameter lists: all comma separated lists
210          of strings were treated as being one string containing commas
211          (fixes #57)
212    
213    * Bug fixes:    * Bug fixes:
214      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
215      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
216        channel audio output device"        channel audio output device"
217        - fixed a crash which occurs when reassigning the same engine
218          on a sampler channel with connected MIDI device
219        - fixed a crash which occurs when changing the number of ports of a MIDI
220          device connected to a sampler channel to number less then or equal
221          to the index of the port to which the sampler channel is connected.
222        - The previous bindings were not been disconnected when altering
223          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
224          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
225        - The active stream/voice count statistic was incorrect.
226        - notification events were not been sent for some sampler
227          channel changes
228        - added default min and max values to restrict the number of allowed
229          audio output channels and MIDI input ports
230        - the connection to the PCM interface is now closed when destroying
231          an audio output device
232        - files with slash in their path or filename could not be loaded
233
