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        - be verbose on DLL load errors (on Linux)
22    
23      * audio driver:
24        - removed the nonsense audio channel constraint (which was hard coded to
25          max. 100 audio channels) for most audio drivers
26        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
27          opposed to the LSCP specs
28        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
29          reflected the wrong value
30        - fixed a memory management bug in ASIO driver
31    
32      * MIDI driver:
33        - added JACK MIDI driver
34    
35      * instruments database:
36        - avoid time consuming samples scanning when adding instruments
37          to the instruments database
38    
39      * Gigasampler format engine:
40        - fixed a memory leak that could happen when a channel was deleted
41          while notes were playing
42        - made it possible to load an instrument even if the audio thread
43          isn't running
44    
45    Version 0.5.1 (6 December 2007)
46    
47      * packaging changes:
48        - added autoconf checks for pthread library
49        - added autoconf check for pthread bug found on certain NPTL-enabled
50          glibc versions (see Gentoo bug report #194076)
51        - added autoconf checks for MS Windows
52    
53      * general changes:
54        - bugfix: the thread used by an editor plugin didn't die when the
55          editor closed
56        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
57          out all the space. operator--() did not apply size_mask after
58          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
59          order to avoid problems with the _NonVolatileReader functions.
60        - bugfix: Stream.h: added a missing divide by BytesPerSample in
61          GetWriteSpace(). Since this function is currently only used in
62          the stream's qsort() compare function, it didn't trigger any
63          bugs.
64        - Resampler.h, Synthesizer.h: cubic interpolation now works in
65          24bit mode too. Faster method to read 24bit words on little
66          endian machines (x86): replaced 3 byte reads + shifts with a 1
67          unaligned 32bit read and shift
68        - experimental support for MS Windows (MIDI input via MME, AUDIO
69          output via ASIO)
70        - made handling of SIGINT signal (Ctrl-C) a bit more robust
71        - support for monitoring the total number of active disk streams
72          (new LSCP commands: GET TOTAL_STREAM_COUNT,
73          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
74    
75      * AUDIO driver:
76        - added Windows ASIO low latency audio driver
77    
78      * MIDI driver:
79        - added MME Windows MIDI driver
80    
81      * LSCP server:
82        - added support for Windows style path / filenames, however with
83          forward slash path separators instead of backslash
84          (i.e. "C:/foo/bar.gig")
85        - allow naughty liblscp to send non-string device parameters within
86          apostrophes as well
87        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
88          "LIST FILE INSTRUMENTS <file>" and
89          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
90          about an arbitrary instrument file on the system where the sampler is
91          running on
92    
93    Version 0.5.0 (15 October 2007)
94    
95      * packaging changes:
96        - config.h is not going to be installed along with liblinuxsampler's
97          API header files anymore
98      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to

104        - fixed buggy boolean --enable-foo / --disable-foo configure script
105          parameters
106        - global.h now only covers global definitions that are needed for the
107          C++ API header files, all implementation internal global definitions
108          are now in global_private.h
109        - atomic.h is not exposed to the C++ API anymore
110        - no need to include config.h anymore for using LS's API header files
111        - fixed warnings in API doc generation

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

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