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        - added autoconf checks for MS Windows
8    
9      * general changes:
10        - bugfix: the thread used by an editor plugin didn't die when the
11          editor closed
12        - bugfix: Ringbuffer.h:
13          fill_write_space_with_null() did not zero out all the space
14          operator--() did not apply size_mask after decrementing the read_ptr
15          DEFAULT_WRAP_ELEMENTS set to 0 in order to avoid problems with
16            the _NonVolatileReader functions.
17         - bugfix: Stream.h: added a missing divide by BytesPerSample in GetWriteSpace()
18           since this function is currently only used in the stream's
19           qsort() compare function, it didn't trigger any bugs
20         Resampler.h, Synthesizer.h:
21           cubic interpolation now works in 24bit mode too
22           faster method to read 24bit words on little endian machines (x86):
23           replaced 3 byte reads + shifts with a 1 unaligned 32bit read and shift
24         Experimental support for MS Windows (MIDI input via MME, AUDIO output via ASIO)
25    
26      * AUDIO driver:
27        - added Windows ASIO low latency audio driver
28    
29      * MIDI driver:
30        - added MME Windows MIDI driver
31    
32      * LSCP server:
33        - added support for Windows style path / filenames, however with
34          forward slash path separators instead of backslash
35          (i.e. "C:/foo/bar.gig")
36        - allow naughty liblscp to send non-string device parameters within
37          apostrophes as well
38    
39    Version 0.5.0 (15 October 2007)
40    
41      * packaging changes:
42        - config.h is not going to be installed along with liblinuxsampler's
43          API header files anymore
44        - only the API relevant header (and source) files will be exported to
45          the Doxygen API documentation (explicitly listed in Doxyfile.in)
46        - added completely new XCode project files for Mac OSX which is now
47          capable to execute our autoconf environment, thus no need anymore
48          to maintain the compile time configuration file (osx/version.h) for
49          OSX manually (patch by Toshi Nagata)
50        - fixed buggy boolean --enable-foo / --disable-foo configure script
51          parameters
52        - global.h now only covers global definitions that are needed for the
53          C++ API header files, all implementation internal global definitions
54          are now in global_private.h
55        - atomic.h is not exposed to the C++ API anymore
56        - no need to include config.h anymore for using LS's API header files
57        - fixed warnings in API doc generation
58

84        controllers        controllers
85      - global (sampler wide) volume can now be controlled at runtime      - global (sampler wide) volume can now be controlled at runtime
86        - Implemented new, improved notification system
87        - fixed compilation errors regarding OSX
88          (patch by Toshi Nagata)
89        - implemented instruments database
90        - added support for escape sequences to the instruments database
91        - added highly experimental support for on-the-fly instrument editing
92          within the sampler's process (by using instrument editor plugins),
93          you'll notice the new "Registered instrument editors:" message on
94          startup, added a new LSCP command:
95          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
96          to spawn a matching instrument editor for the instrument on the
97          given sampler channel, the plugin path can be overridden at compile
98          time with ./configure --enable-plugin-dir=/some/dir
99        - added experimental code for synchronizing instrument editors hosted
100          in the sampler's process to safely edit instruments while playing
101          without a crash (hopefully) by either suspending single regions
102          wherever possible or if unavoidable whole engine(s)
103        - fixed several issues in fundamental "Thread" class: set scheduling
104          policy and priority on thread level, set a minimum stack size for
105          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
106          threads simply inherited properties of starting thread instead of
107          setting their own policy and priority
108        - minor fix in our automatic stack trace mechanism on crashes, the
109          main process did not wait for the stack trace process to finish
110          its output
111        - fixed some minor memory leaks
112        - reenabled assembly features support, at the moment only for
113          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
114        - minor assembly fix in x86 features detection (don't use the PIC
115          register, to avoid relocations in the text segment at runtime)
116        - POSIX callback functions of Thread.h are hidden
117    
118    * MIDI driver:    * MIDI driver:
119      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
120    
121      * audio driver:
122        - the ALSA audio output driver parameters now reflect the correct
123          parameter value ranges for the respective selected sound card
124          (patch by Till Wimmer, a bit fixed and extended)
125    
126    * Gigasampler format engine:    * Gigasampler format engine:
127      - if a filter is used and EG2 finishes before EG1, let the voice      - if a filter is used and EG2 finishes before EG1, let the voice
128        die when EG2 has finished (this fixes a problem with clicks and        die when EG2 has finished (this fixes a problem with clicks and
129        voice starvation for some gigs)        voice starvation for some gigs)
130        - playback is no longer disabled during instrument loading
131        - all notes playing on a channel that changes its instrument keep
132          playing with the old instrument until they get a note off
133          command
134        - EG fix: a release value of zero could cause noises or crash
135        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
136        - EG fine tuning: when attack is zero the EG starts at a level
137          above max sustain level, which means that there is a decay phase
138          even if sustain is 100%
139        - more EG fixes: the level could sometimes go below zero and cause
140          noises or crashes
141        - minor fix of EGDecay (patch by Toshi Nagata)
142        - fixed compiler error when --enable-override-filter-type was
143          supplied to the configure script (fixes #46)
144        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
145          instead of a fix value
146        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
147          127 (solo mode) only kill voices if the respective mode really
148          changed
149    
150      * LSCP server:
151        - fixed compile time error for old Bison versions
152          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
153        - parser now supports extended ASCII character set
154          (up to ASCII code 255, i.e. includes now umlauts and accents)
155        - filename arguments in LSCP commands now allow to use escape
156          sequences, that is directly literal as one of: \', \", \\, \n, \r,
157          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
158          code value like \xf2) (fixes bug #24)
159        - the following LSCP commands now also support escape sequences for at
160          least one of their text-based parameters (i.e. name, description):
161          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
162          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
163          "SET DB_INSTRUMENT_DIRECTORY NAME",
164          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
165          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
166          "FIND DB_INSTRUMENT_DIRECTORIES"
167        - returns verbose syntax errors (line and column where syntax error
168          occured, the unexpected character and the actually expected, possible
169          character(s), the latter only if less than 5 possibilities)
170        - made sure that LSCP syntax is not affected by gigedit locale
171          settings
172        - bugfix regarding strings parameter lists: all comma separated lists
173          of strings were treated as being one string containing commas
174          (fixes #57)
175    
176    * Bug fixes:    * Bug fixes:
177      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
178        - another thread safety fix for lscp "load engine" and "set
179          channel audio output device"
180        - fixed a crash which occurs when reassigning the same engine
181          on a sampler channel with connected MIDI device
182        - fixed a crash which occurs when changing the number of ports of a MIDI
183          device connected to a sampler channel to number less then or equal
184          to the index of the port to which the sampler channel is connected.
185        - The previous bindings were not been disconnected when altering
186          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
187          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
188        - The active stream/voice count statistic was incorrect.
189        - notification events were not been sent for some sampler
190          channel changes
191        - added default min and max values to restrict the number of allowed
192          audio output channels and MIDI input ports
193        - the connection to the PCM interface is now closed when destroying
194          an audio output device
195        - files with slash in their path or filename could not be loaded
196    
197      * test cases:
198        - updated and fixed (haven't been touched in a while)
