# Line 1  Line 1 
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    
49    Version 0.5.1 (6 December 2007)
50    
51      * packaging changes:
52        - added autoconf checks for pthread library
53        - added autoconf check for pthread bug found on certain NPTL-enabled
54          glibc versions (see Gentoo bug report #194076)
55        - added autoconf checks for MS Windows
56    
57      * general changes:
58        - bugfix: the thread used by an editor plugin didn't die when the
59          editor closed
60        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
61          out all the space. operator--() did not apply size_mask after
62          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
63          order to avoid problems with the _NonVolatileReader functions.
64        - bugfix: Stream.h: added a missing divide by BytesPerSample in
65          GetWriteSpace(). Since this function is currently only used in
66          the stream's qsort() compare function, it didn't trigger any
67          bugs.
68        - Resampler.h, Synthesizer.h: cubic interpolation now works in
69          24bit mode too. Faster method to read 24bit words on little
70          endian machines (x86): replaced 3 byte reads + shifts with a 1
71          unaligned 32bit read and shift
72        - experimental support for MS Windows (MIDI input via MME, AUDIO
73          output via ASIO)
74        - made handling of SIGINT signal (Ctrl-C) a bit more robust
75        - support for monitoring the total number of active disk streams
76          (new LSCP commands: GET TOTAL_STREAM_COUNT,
77          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
78    
79      * AUDIO driver:
80        - added Windows ASIO low latency audio driver
81    
82      * MIDI driver:
83        - added MME Windows MIDI driver
84    
85      * LSCP server:
86        - added support for Windows style path / filenames, however with
87          forward slash path separators instead of backslash
88          (i.e. "C:/foo/bar.gig")
89        - allow naughty liblscp to send non-string device parameters within
90          apostrophes as well
91        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
92          "LIST FILE INSTRUMENTS <file>" and
93          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
94          about an arbitrary instrument file on the system where the sampler is
95          running on
96    
97    Version 0.5.0 (15 October 2007)
98    
99      * packaging changes:
100        - config.h is not going to be installed along with liblinuxsampler's
101          API header files anymore
102      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to
103        the Doxygen API documentation (explicitly listed in Doxyfile.in)        the Doxygen API documentation (explicitly listed in Doxyfile.in)
104        - added completely new XCode project files for Mac OSX which is now
105          capable to execute our autoconf environment, thus no need anymore
106          to maintain the compile time configuration file (osx/version.h) for
107          OSX manually (patch by Toshi Nagata)
108        - fixed buggy boolean --enable-foo / --disable-foo configure script
109          parameters
110        - global.h now only covers global definitions that are needed for the
111          C++ API header files, all implementation internal global definitions
112          are now in global_private.h
113        - atomic.h is not exposed to the C++ API anymore
114        - no need to include config.h anymore for using LS's API header files
115        - fixed warnings in API doc generation
116

143      - global (sampler wide) volume can now be controlled at runtime      - global (sampler wide) volume can now be controlled at runtime
144      - Implemented new, improved notification system      - Implemented new, improved notification system
145        - fixed compilation errors regarding OSX
146          (patch by Toshi Nagata)
147        - implemented instruments database
148        - added support for escape sequences to the instruments database
149        - added highly experimental support for on-the-fly instrument editing
150          within the sampler's process (by using instrument editor plugins),
151          you'll notice the new "Registered instrument editors:" message on
152          startup, added a new LSCP command:
153          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
154          to spawn a matching instrument editor for the instrument on the
155          given sampler channel, the plugin path can be overridden at compile
156          time with ./configure --enable-plugin-dir=/some/dir
157        - added experimental code for synchronizing instrument editors hosted
158          in the sampler's process to safely edit instruments while playing
159          without a crash (hopefully) by either suspending single regions
160          wherever possible or if unavoidable whole engine(s)
161        - fixed several issues in fundamental "Thread" class: set scheduling
162          policy and priority on thread level, set a minimum stack size for
163          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
164          threads simply inherited properties of starting thread instead of
165          setting their own policy and priority
166        - minor fix in our automatic stack trace mechanism on crashes, the
167          main process did not wait for the stack trace process to finish
168          its output
169        - fixed some minor memory leaks
170        - reenabled assembly features support, at the moment only for
171          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
172        - minor assembly fix in x86 features detection (don't use the PIC
173          register, to avoid relocations in the text segment at runtime)
174        - POSIX callback functions of Thread.h are hidden
175    
176    * MIDI driver:    * MIDI driver:
177      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages

196        even if sustain is 100%        even if sustain is 100%
197        - more EG fixes: the level could sometimes go below zero and cause
198          noises or crashes
199        - minor fix of EGDecay (patch by Toshi Nagata)
200        - fixed compiler error when --enable-override-filter-type was
201          supplied to the configure script (fixes #46)
202        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
203          instead of a fix value
204        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
205          127 (solo mode) only kill voices if the respective mode really
206          changed
207    
208      * LSCP server:
209        - fixed compile time error for old Bison versions
210          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
211        - parser now supports extended ASCII character set
212          (up to ASCII code 255, i.e. includes now umlauts and accents)
213        - filename arguments in LSCP commands now allow to use escape
214          sequences, that is directly literal as one of: \', \", \\, \n, \r,
215          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
216          code value like \xf2) (fixes bug #24)
217        - the following LSCP commands now also support escape sequences for at
218          least one of their text-based parameters (i.e. name, description):
219          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
220          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
221          "SET DB_INSTRUMENT_DIRECTORY NAME",
222          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
223          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
224          "FIND DB_INSTRUMENT_DIRECTORIES"
225        - returns verbose syntax errors (line and column where syntax error
226          occured, the unexpected character and the actually expected, possible
227          character(s), the latter only if less than 5 possibilities)
228        - made sure that LSCP syntax is not affected by gigedit locale
229          settings
230        - bugfix regarding strings parameter lists: all comma separated lists
231          of strings were treated as being one string containing commas
232          (fixes #57)
233    
234    * Bug fixes:    * Bug fixes:
235      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
236      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
237        channel audio output device"        channel audio output device"
238        - fixed a crash which occurs when reassigning the same engine
239          on a sampler channel with connected MIDI device
240        - fixed a crash which occurs when changing the number of ports of a MIDI
241          device connected to a sampler channel to number less then or equal
242          to the index of the port to which the sampler channel is connected.
243        - The previous bindings were not been disconnected when altering
244          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
245          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
246        - The active stream/voice count statistic was incorrect.
247        - notification events were not been sent for some sampler
248          channel changes
249        - added default min and max values to restrict the number of allowed
250          audio output channels and MIDI input ports
251        - the connection to the PCM interface is now closed when destroying
252          an audio output device
253        - files with slash in their path or filename could not be loaded
254    
255      * test cases:
256        - updated and fixed (haven't been touched in a while)
