1  Version CVS HEAD (?)  Version 0.5.1 (6 December 2007)
2    
3    * packaging changes:    * 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: fill_write_space_with_null() did not zero
13          out all the space. operator--() did not apply size_mask after
14          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
15          order to avoid problems with the _NonVolatileReader functions.
16        - bugfix: Stream.h: added a missing divide by BytesPerSample in
17          GetWriteSpace(). Since this function is currently only used in
18          the stream's qsort() compare function, it didn't trigger any
19          bugs.
20        - Resampler.h, Synthesizer.h: cubic interpolation now works in
21          24bit mode too. Faster method to read 24bit words on little
22          endian machines (x86): replaced 3 byte reads + shifts with a 1
23          unaligned 32bit read and shift
24        - experimental support for MS Windows (MIDI input via MME, AUDIO
25          output via ASIO)
26        - made handling of SIGINT signal (Ctrl-C) a bit more robust
27        - support for monitoring the total number of active disk streams
28          (new LSCP commands: GET TOTAL_STREAM_COUNT,
29          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
30    
31      * AUDIO driver:
32        - added Windows ASIO low latency audio driver
33    
34      * MIDI driver:
35        - added MME Windows MIDI driver
36    
37      * LSCP server:
38        - added support for Windows style path / filenames, however with
39          forward slash path separators instead of backslash
40          (i.e. "C:/foo/bar.gig")
41        - allow naughty liblscp to send non-string device parameters within
42          apostrophes as well
43        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
44          "LIST FILE INSTRUMENTS <file>" and
45          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
46          about an arbitrary instrument file on the system where the sampler is
47          running on
48    
49    Version 0.5.0 (15 October 2007)
50    
51      * packaging changes:
52        - config.h is not going to be installed along with liblinuxsampler's
53          API header files anymore
54      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to

60        - fixed buggy boolean --enable-foo / --disable-foo configure script
61          parameters
62        - global.h now only covers global definitions that are needed for the
63          C++ API header files, all implementation internal global definitions
64          are now in global_private.h
65        - atomic.h is not exposed to the C++ API anymore
66        - no need to include config.h anymore for using LS's API header files
67        - fixed warnings in API doc generation

99      - implemented instruments database      - implemented instruments database
100        - added support for escape sequences to the instruments database
101        - added highly experimental support for on-the-fly instrument editing
102          within the sampler's process (by using instrument editor plugins),
103          you'll notice the new "Registered instrument editors:" message on
104          startup, added a new LSCP command:
105          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
106          to spawn a matching instrument editor for the instrument on the
107          given sampler channel, the plugin path can be overridden at compile
108          time with ./configure --enable-plugin-dir=/some/dir
109        - added experimental code for synchronizing instrument editors hosted
110          in the sampler's process to safely edit instruments while playing
111          without a crash (hopefully) by either suspending single regions
112          wherever possible or if unavoidable whole engine(s)
113        - fixed several issues in fundamental "Thread" class: set scheduling
114          policy and priority on thread level, set a minimum stack size for
115          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
116          threads simply inherited properties of starting thread instead of
117          setting their own policy and priority
118        - minor fix in our automatic stack trace mechanism on crashes, the
119          main process did not wait for the stack trace process to finish
120          its output
121        - fixed some minor memory leaks
122        - reenabled assembly features support, at the moment only for
123          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
124        - minor assembly fix in x86 features detection (don't use the PIC
125          register, to avoid relocations in the text segment at runtime)
126        - POSIX callback functions of Thread.h are hidden
127    
128    * MIDI driver:    * MIDI driver:
129      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages

152        - fixed compiler error when --enable-override-filter-type was
153          supplied to the configure script (fixes #46)
154        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
155          instead of a fix value
156        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
157          127 (solo mode) only kill voices if the respective mode really
158          changed
159    
160      * LSCP server:
161        - fixed compile time error for old Bison versions
162          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
163        - parser now supports extended ASCII character set
164          (up to ASCII code 255, i.e. includes now umlauts and accents)
165        - filename arguments in LSCP commands now allow to use escape
166          sequences, that is directly literal as one of: \', \", \\, \n, \r,
167          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
168          code value like \xf2) (fixes bug #24)
169        - the following LSCP commands now also support escape sequences for at
170          least one of their text-based parameters (i.e. name, description):
171          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
172          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
173          "SET DB_INSTRUMENT_DIRECTORY NAME",
174          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
175          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
176          "FIND DB_INSTRUMENT_DIRECTORIES"
177        - returns verbose syntax errors (line and column where syntax error
178          occured, the unexpected character and the actually expected, possible
179          character(s), the latter only if less than 5 possibilities)
180        - made sure that LSCP syntax is not affected by gigedit locale
181          settings
182        - bugfix regarding strings parameter lists: all comma separated lists
183          of strings were treated as being one string containing commas
184          (fixes #57)
185    
186    * Bug fixes:    * Bug fixes:
187      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
188      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
189        channel audio output device"        channel audio output device"
190        - fixed a crash which occurs when reassigning the same engine
191          on a sampler channel with connected MIDI device
192        - fixed a crash which occurs when changing the number of ports of a MIDI
193          device connected to a sampler channel to number less then or equal
194          to the index of the port to which the sampler channel is connected.
195        - The previous bindings were not been disconnected when altering
196          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
197          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
198        - The active stream/voice count statistic was incorrect.
199        - notification events were not been sent for some sampler
200          channel changes
201        - added default min and max values to restrict the number of allowed
202          audio output channels and MIDI input ports
203        - the connection to the PCM interface is now closed when destroying
204          an audio output device
205        - files with slash in their path or filename could not be loaded
206
