1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3      * packaging changes:
4        - added autoconf checks for pthread library
5        - added autoconf check for pthread bug found on certain NPTL-enabled
6          glibc versions (see Gentoo bug report #194076)
7    
8      * general changes:
9        - bugfix: the thread used by an editor plugin didn't die when the
10          editor closed
11        - bugfix: Ringbuffer.h:
12          fill_write_space_with_null() did not zero out all the space
13          operator--() did not apply size_mask after decrementing the read_ptr
14          DEFAULT_WRAP_ELEMENTS set to 0 in order to avoid problems with
15            the _NonVolatileReader functions.
16         - bugfix: Stream.h: added a missing divide by BytesPerSample in GetWriteSpace()
17           since this function is currently only used in the stream's
18           qsort() compare function, it didn't trigger any bugs
19         Resampler.h, Synthesizer.h:
20           cubic interpolation now works in 24bit mode too
21           faster method to read 24bit words on little endian machines (x86):
22           replaced 3 byte reads + shifts with a 1 unaligned 32bit read and shift
23    
24      * MIDI driver:
25        - added MME Windows MIDI driver      
26    
27      * LSCP server:
28        - added support for Windows style path / filenames, however with
29          forward slash path separators instead of backslash
30          (i.e. "C:/foo/bar.gig")
31    
32    Version 0.5.0 (15 October 2007)
33    
34      * packaging changes:
35        - config.h is not going to be installed along with liblinuxsampler's
36          API header files anymore
37        - only the API relevant header (and source) files will be exported to
38          the Doxygen API documentation (explicitly listed in Doxyfile.in)
39        - added completely new XCode project files for Mac OSX which is now
40          capable to execute our autoconf environment, thus no need anymore
41          to maintain the compile time configuration file (osx/version.h) for
42          OSX manually (patch by Toshi Nagata)
43        - fixed buggy boolean --enable-foo / --disable-foo configure script
44          parameters
45        - global.h now only covers global definitions that are needed for the
46          C++ API header files, all implementation internal global definitions
47          are now in global_private.h
48        - atomic.h is not exposed to the C++ API anymore
49        - no need to include config.h anymore for using LS's API header files
50        - fixed warnings in API doc generation

77        controllers        controllers
78      - global (sampler wide) volume can now be controlled at runtime      - global (sampler wide) volume can now be controlled at runtime
79        - Implemented new, improved notification system
80        - fixed compilation errors regarding OSX
81          (patch by Toshi Nagata)
82        - implemented instruments database
83        - added support for escape sequences to the instruments database
84        - added highly experimental support for on-the-fly instrument editing
85          within the sampler's process (by using instrument editor plugins),
86          you'll notice the new "Registered instrument editors:" message on
87          startup, added a new LSCP command:
88          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
89          to spawn a matching instrument editor for the instrument on the
90          given sampler channel, the plugin path can be overridden at compile
91          time with ./configure --enable-plugin-dir=/some/dir
92        - added experimental code for synchronizing instrument editors hosted
93          in the sampler's process to safely edit instruments while playing
94          without a crash (hopefully) by either suspending single regions
95          wherever possible or if unavoidable whole engine(s)
96        - fixed several issues in fundamental "Thread" class: set scheduling
97          policy and priority on thread level, set a minimum stack size for
98          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
99          threads simply inherited properties of starting thread instead of
100          setting their own policy and priority
101        - minor fix in our automatic stack trace mechanism on crashes, the
102          main process did not wait for the stack trace process to finish
103          its output
104        - fixed some minor memory leaks
105        - reenabled assembly features support, at the moment only for
106          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
107        - minor assembly fix in x86 features detection (don't use the PIC
108          register, to avoid relocations in the text segment at runtime)
109        - POSIX callback functions of Thread.h are hidden
110    
111    * MIDI driver:    * MIDI driver:
112      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
113    
114      * audio driver:
115        - the ALSA audio output driver parameters now reflect the correct
116          parameter value ranges for the respective selected sound card
117          (patch by Till Wimmer, a bit fixed and extended)
118

127      - EG fix: a release value of zero could cause noises or crash      - EG fix: a release value of zero could cause noises or crash
128      - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)      - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
129        - EG fine tuning: when attack is zero the EG starts at a level
130          above max sustain level, which means that there is a decay phase
131          even if sustain is 100%
132        - more EG fixes: the level could sometimes go below zero and cause
133          noises or crashes
134        - minor fix of EGDecay (patch by Toshi Nagata)
135        - fixed compiler error when --enable-override-filter-type was
136          supplied to the configure script (fixes #46)
137        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
138          instead of a fix value
139        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
140          127 (solo mode) only kill voices if the respective mode really
141          changed
142    
143      * LSCP server:
144        - fixed compile time error for old Bison versions
145          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
146        - parser now supports extended ASCII character set
147          (up to ASCII code 255, i.e. includes now umlauts and accents)
148        - filename arguments in LSCP commands now allow to use escape
149          sequences, that is directly literal as one of: \', \", \\, \n, \r,
150          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
151          code value like \xf2) (fixes bug #24)
152        - the following LSCP commands now also support escape sequences for at
153          least one of their text-based parameters (i.e. name, description):
154          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
155          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
156          "SET DB_INSTRUMENT_DIRECTORY NAME",
157          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
158          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
159          "FIND DB_INSTRUMENT_DIRECTORIES"
160        - returns verbose syntax errors (line and column where syntax error
161          occured, the unexpected character and the actually expected, possible
162          character(s), the latter only if less than 5 possibilities)
163        - made sure that LSCP syntax is not affected by gigedit locale
164          settings
165        - bugfix regarding strings parameter lists: all comma separated lists
166          of strings were treated as being one string containing commas
167          (fixes #57)
168    
169    * Bug fixes:    * Bug fixes:
170      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
171      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
172        channel audio output device"        channel audio output device"
173        - fixed a crash which occurs when reassigning the same engine
174          on a sampler channel with connected MIDI device
175        - fixed a crash which occurs when changing the number of ports of a MIDI
176          device connected to a sampler channel to number less then or equal
177          to the index of the port to which the sampler channel is connected.
178        - The previous bindings were not been disconnected when altering
179          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
180          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
181        - The active stream/voice count statistic was incorrect.
182        - notification events were not been sent for some sampler
183          channel changes
184        - added default min and max values to restrict the number of allowed
185          audio output channels and MIDI input ports
186        - the connection to the PCM interface is now closed when destroying
187          an audio output device
188        - files with slash in their path or filename could not be loaded
189
