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      * AUDIO driver:
25        - added Windows ASIO low latency audio driver
26    
27      * MIDI driver:
28        - added MME Windows MIDI driver
29    
30      * LSCP server:
31        - added support for Windows style path / filenames, however with
32          forward slash path separators instead of backslash
33          (i.e. "C:/foo/bar.gig")
34        - allow naughty liblscp to send non-string device parameters within
35          apostrophes as well
36    
37    Version 0.5.0 (15 October 2007)
38    
39      * packaging changes:
40        - config.h is not going to be installed along with liblinuxsampler's
41          API header files anymore
42        - only the API relevant header (and source) files will be exported to
43          the Doxygen API documentation (explicitly listed in Doxyfile.in)
44        - added completely new XCode project files for Mac OSX which is now
45          capable to execute our autoconf environment, thus no need anymore
46          to maintain the compile time configuration file (osx/version.h) for
47          OSX manually (patch by Toshi Nagata)
48        - fixed buggy boolean --enable-foo / --disable-foo configure script
49          parameters
50        - global.h now only covers global definitions that are needed for the
51          C++ API header files, all implementation internal global definitions
52          are now in global_private.h
53        - atomic.h is not exposed to the C++ API anymore
54        - no need to include config.h anymore for using LS's API header files
55        - fixed warnings in API doc generation

82        controllers        controllers
83      - global (sampler wide) volume can now be controlled at runtime      - global (sampler wide) volume can now be controlled at runtime
84        - Implemented new, improved notification system
85        - fixed compilation errors regarding OSX
86          (patch by Toshi Nagata)
87        - implemented instruments database
88        - added support for escape sequences to the instruments database
89        - added highly experimental support for on-the-fly instrument editing
90          within the sampler's process (by using instrument editor plugins),
91          you'll notice the new "Registered instrument editors:" message on
92          startup, added a new LSCP command:
93          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
94          to spawn a matching instrument editor for the instrument on the
95          given sampler channel, the plugin path can be overridden at compile
96          time with ./configure --enable-plugin-dir=/some/dir
97        - added experimental code for synchronizing instrument editors hosted
98          in the sampler's process to safely edit instruments while playing
99          without a crash (hopefully) by either suspending single regions
100          wherever possible or if unavoidable whole engine(s)
101        - fixed several issues in fundamental "Thread" class: set scheduling
102          policy and priority on thread level, set a minimum stack size for
103          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
104          threads simply inherited properties of starting thread instead of
105          setting their own policy and priority
106        - minor fix in our automatic stack trace mechanism on crashes, the
107          main process did not wait for the stack trace process to finish
108          its output
109        - fixed some minor memory leaks
110        - reenabled assembly features support, at the moment only for
111          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
112        - minor assembly fix in x86 features detection (don't use the PIC
113          register, to avoid relocations in the text segment at runtime)
114        - POSIX callback functions of Thread.h are hidden
115    
116    * MIDI driver:    * MIDI driver:
117      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
118    
119      * audio driver:
120        - the ALSA audio output driver parameters now reflect the correct
121          parameter value ranges for the respective selected sound card
122          (patch by Till Wimmer, a bit fixed and extended)
123

131        command        command
132        - EG fix: a release value of zero could cause noises or crash
133        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
134        - EG fine tuning: when attack is zero the EG starts at a level
135          above max sustain level, which means that there is a decay phase
136          even if sustain is 100%
137        - more EG fixes: the level could sometimes go below zero and cause
138          noises or crashes
139        - minor fix of EGDecay (patch by Toshi Nagata)
140        - fixed compiler error when --enable-override-filter-type was
141          supplied to the configure script (fixes #46)
142        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
143          instead of a fix value
144        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
145          127 (solo mode) only kill voices if the respective mode really
146          changed
147    
148      * LSCP server:
149        - fixed compile time error for old Bison versions
150          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
151        - parser now supports extended ASCII character set
152          (up to ASCII code 255, i.e. includes now umlauts and accents)
153        - filename arguments in LSCP commands now allow to use escape
154          sequences, that is directly literal as one of: \', \", \\, \n, \r,
155          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
156          code value like \xf2) (fixes bug #24)
157        - the following LSCP commands now also support escape sequences for at
158          least one of their text-based parameters (i.e. name, description):
159          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
160          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
161          "SET DB_INSTRUMENT_DIRECTORY NAME",
162          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
163          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
164          "FIND DB_INSTRUMENT_DIRECTORIES"
165        - returns verbose syntax errors (line and column where syntax error
166          occured, the unexpected character and the actually expected, possible
167          character(s), the latter only if less than 5 possibilities)
168        - made sure that LSCP syntax is not affected by gigedit locale
169          settings
170        - bugfix regarding strings parameter lists: all comma separated lists
171          of strings were treated as being one string containing commas
172          (fixes #57)
173    
174    * Bug fixes:    * Bug fixes:
175      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
176      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
177        channel audio output device"        channel audio output device"
178        - fixed a crash which occurs when reassigning the same engine
179          on a sampler channel with connected MIDI device
180        - fixed a crash which occurs when changing the number of ports of a MIDI
181          device connected to a sampler channel to number less then or equal
182          to the index of the port to which the sampler channel is connected.
183        - The previous bindings were not been disconnected when altering
184          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
185          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
186        - The active stream/voice count statistic was incorrect.
187        - notification events were not been sent for some sampler
188          channel changes
189        - added default min and max values to restrict the number of allowed
190          audio output channels and MIDI input ports
191        - the connection to the PCM interface is now closed when destroying
192          an audio output device
193        - files with slash in their path or filename could not be loaded
194    
195      * test cases:
196        - updated and fixed (haven't been touched in a while)
