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        - fixed compilation with gcc 4.3
9    
10      * general changes:
11        - bugfix: on some POSIX systems instrument editor plugins refused to
12          load as we used a non-portable Linux specific struct field
13          (fixes bug #70, patch by Ronald Baljeu)
14        - fixed endless loop which occured when loading an instrument editor
15          plugin DLL on Windows systems failed
16        - fixed memory leaks that occurred when liblinuxsampler was unloaded
17        - optimized the SynchronizedConfig class so it doesn't wait
18          unnecessarily long after an update
19        - added support for notifying instrument editors on note-on / note-off
20          events (e.g. to highlight the pressed keys on the virtual keyboard
21          of gigedit)
22        - added support for triggering notes by instrument editors (see above)
23        - be verbose on DLL load errors (on Linux)
24        - fixed di-harmonic triangle LFO implementation (this LFO implementation
25          is only used by very few systems, most pick the int math
26          implementation, which is usually faster)
27    
28      * audio driver:
29        - removed the nonsense audio channel constraint (which was hard coded to
30          max. 100 audio channels) for most audio drivers
31        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
32          opposed to the LSCP specs
33        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
34          reflected the wrong value
35        - fixed a memory management bug in ASIO driver
36    
37      * MIDI driver:
38        - added JACK MIDI driver
39        - dispatch bank select as ordinary CC as well, the user might seriously
40          want to (mis)use it for some purpose ("fixed" in all current MIDI
41          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
42    
43      * instruments database:
44        - avoid time consuming samples scanning when adding instruments
45          to the instruments database
46    
47      * Gigasampler format engine:
48        - fixed a memory leak that could happen when a channel was deleted
49          while notes were playing
50        - made it possible to load an instrument even if the audio thread
51          isn't running
52        - added partial support for the "Controller Triggered" MIDI rule,
53          enough for piano gigs with pedal noise samples
54        - minor fix: only mark FX sends as being modified if really the
55          respective FX send MIDI controller was used
56        - added support for GM global device volume SysEx message
57    
58      * LSCP server:
59        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
60          react on MIDI data arriving on certain sampler channels (so far only
61          Note-On and Note-Off events are sent via this LSCP event)
62        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
63          react on MIDI data arriving on certain MIDI input devices (so far only
64          Note-On and Note-Off events are sent via this LSCP event)
65    
66    Version 0.5.1 (6 December 2007)
67    
68      * packaging changes:
69        - added autoconf checks for pthread library
70        - added autoconf check for pthread bug found on certain NPTL-enabled
71          glibc versions (see Gentoo bug report #194076)
72        - added autoconf checks for MS Windows
73    
74      * general changes:
75        - bugfix: the thread used by an editor plugin didn't die when the
76          editor closed
77        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
78          out all the space. operator--() did not apply size_mask after
79          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
80          order to avoid problems with the _NonVolatileReader functions.
81        - bugfix: Stream.h: added a missing divide by BytesPerSample in
82          GetWriteSpace(). Since this function is currently only used in
83          the stream's qsort() compare function, it didn't trigger any
84          bugs.
85        - Resampler.h, Synthesizer.h: cubic interpolation now works in
86          24bit mode too. Faster method to read 24bit words on little
87          endian machines (x86): replaced 3 byte reads + shifts with a 1
88          unaligned 32bit read and shift
89        - experimental support for MS Windows (MIDI input via MME, AUDIO
90          output via ASIO)
91        - made handling of SIGINT signal (Ctrl-C) a bit more robust
92        - support for monitoring the total number of active disk streams
93          (new LSCP commands: GET TOTAL_STREAM_COUNT,
94          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
95    
96      * AUDIO driver:
97        - added Windows ASIO low latency audio driver
98    
99      * MIDI driver:
100        - added MME Windows MIDI driver
101    
102      * LSCP server:
103        - added support for Windows style path / filenames, however with
104          forward slash path separators instead of backslash
105          (i.e. "C:/foo/bar.gig")
106        - allow naughty liblscp to send non-string device parameters within
107          apostrophes as well
108        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
109          "LIST FILE INSTRUMENTS <file>" and
110          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
111          about an arbitrary instrument file on the system where the sampler is
112          running on
113    
114    Version 0.5.0 (15 October 2007)
115    
116      * packaging changes:
117        - config.h is not going to be installed along with liblinuxsampler's
118          API header files anymore
119      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to
120        the Doxygen API documentation (explicitly listed in Doxyfile.in)        the Doxygen API documentation (explicitly listed in Doxyfile.in)
121        - added completely new XCode project files for Mac OSX which is now
122          capable to execute our autoconf environment, thus no need anymore
123          to maintain the compile time configuration file (osx/version.h) for
124          OSX manually (patch by Toshi Nagata)
125        - fixed buggy boolean --enable-foo / --disable-foo configure script
126          parameters
127        - global.h now only covers global definitions that are needed for the
128          C++ API header files, all implementation internal global definitions
129          are now in global_private.h
130        - atomic.h is not exposed to the C++ API anymore
131        - no need to include config.h anymore for using LS's API header files
132        - fixed warnings in API doc generation
133

160      - global (sampler wide) volume can now be controlled at runtime      - global (sampler wide) volume can now be controlled at runtime
161      - Implemented new, improved notification system      - Implemented new, improved notification system
162        - fixed compilation errors regarding OSX
163          (patch by Toshi Nagata)
164        - implemented instruments database
165        - added support for escape sequences to the instruments database
166        - added highly experimental support for on-the-fly instrument editing
167          within the sampler's process (by using instrument editor plugins),
168          you'll notice the new "Registered instrument editors:" message on
169          startup, added a new LSCP command:
170          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
171          to spawn a matching instrument editor for the instrument on the
172          given sampler channel, the plugin path can be overridden at compile
173          time with ./configure --enable-plugin-dir=/some/dir
174        - added experimental code for synchronizing instrument editors hosted
175          in the sampler's process to safely edit instruments while playing
176          without a crash (hopefully) by either suspending single regions
177          wherever possible or if unavoidable whole engine(s)
178        - fixed several issues in fundamental "Thread" class: set scheduling
179          policy and priority on thread level, set a minimum stack size for
180          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
181          threads simply inherited properties of starting thread instead of
182          setting their own policy and priority
183        - minor fix in our automatic stack trace mechanism on crashes, the
184          main process did not wait for the stack trace process to finish
185          its output
186        - fixed some minor memory leaks
187        - reenabled assembly features support, at the moment only for
188          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
189        - minor assembly fix in x86 features detection (don't use the PIC
190          register, to avoid relocations in the text segment at runtime)
191        - POSIX callback functions of Thread.h are hidden
192

216        - minor fix of EGDecay (patch by Toshi Nagata)
217        - fixed compiler error when --enable-override-filter-type was
218          supplied to the configure script (fixes #46)
219        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
220          instead of a fix value
221        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
222          127 (solo mode) only kill voices if the respective mode really
223          changed
224    
225      * LSCP server:
226        - fixed compile time error for old Bison versions
227          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
228        - parser now supports extended ASCII character set
229          (up to ASCII code 255, i.e. includes now umlauts and accents)
230        - filename arguments in LSCP commands now allow to use escape
231          sequences, that is directly literal as one of: \', \", \\, \n, \r,
232          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
233          code value like \xf2) (fixes bug #24)
234        - the following LSCP commands now also support escape sequences for at
235          least one of their text-based parameters (i.e. name, description):
236          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
237          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
238          "SET DB_INSTRUMENT_DIRECTORY NAME",
239          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
240          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
241          "FIND DB_INSTRUMENT_DIRECTORIES"
242        - returns verbose syntax errors (line and column where syntax error
243          occured, the unexpected character and the actually expected, possible
244          character(s), the latter only if less than 5 possibilities)
245        - made sure that LSCP syntax is not affected by gigedit locale
246          settings
247        - bugfix regarding strings parameter lists: all comma separated lists
248          of strings were treated as being one string containing commas
249          (fixes #57)
250    
251    * Bug fixes:    * Bug fixes:
252      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
253      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
254        channel audio output device"        channel audio output device"
255        - fixed a crash which occurs when reassigning the same engine
256          on a sampler channel with connected MIDI device
257        - fixed a crash which occurs when changing the number of ports of a MIDI
258          device connected to a sampler channel to number less then or equal
259          to the index of the port to which the sampler channel is connected.
260        - The previous bindings were not been disconnected when altering
261          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
262          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
263        - The active stream/voice count statistic was incorrect.
264        - notification events were not been sent for some sampler
265          channel changes
266        - added default min and max values to restrict the number of allowed
267          audio output channels and MIDI input ports
268        - the connection to the PCM interface is now closed when destroying
269          an audio output device
270        - files with slash in their path or filename could not be loaded
271
