# Line 1  Line 1 
1  Version CVS HEAD (?)  Version 0.5.1 (6 December 2007)
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: 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
55          the Doxygen API documentation (explicitly listed in Doxyfile.in)
56        - added completely new XCode project files for Mac OSX which is now
57          capable to execute our autoconf environment, thus no need anymore
58          to maintain the compile time configuration file (osx/version.h) for
59          OSX manually (patch by Toshi Nagata)
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
68

83          MIDI instrument maps and assign each sampler channel individually
84          a certain map, so that i.e. separation of normal instruments and
85          drumkits is possible
86        - new notification events for tracking changes to audio/MIDI devices,
87          MIDI instrument maps, MIDI instruments, FX sends, global volume.
88        - sampler was limited to load max. 200 instruments in the background
89          due to a constant size RingBuffer FIFO which is now replaced by a
90          dynamic (unlimited) size std::list FIFO
91        - added FX sends, these allow to route audio signals to arbitrary audio
92          output channels for being processed by external effect processors
93          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
94          controllers
95        - global (sampler wide) volume can now be controlled at runtime
96        - Implemented new, improved notification system
97        - fixed compilation errors regarding OSX
98          (patch by Toshi Nagata)
99        - 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
130    
131      * audio driver:
132        - the ALSA audio output driver parameters now reflect the correct
133          parameter value ranges for the respective selected sound card
134          (patch by Till Wimmer, a bit fixed and extended)
135    
136      * Gigasampler format engine:
137        - if a filter is used and EG2 finishes before EG1, let the voice
138          die when EG2 has finished (this fixes a problem with clicks and
139          voice starvation for some gigs)
140        - playback is no longer disabled during instrument loading
141        - all notes playing on a channel that changes its instrument keep
142          playing with the old instrument until they get a note off
143          command
144        - EG fix: a release value of zero could cause noises or crash
145        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
146        - EG fine tuning: when attack is zero the EG starts at a level
147          above max sustain level, which means that there is a decay phase
148          even if sustain is 100%
149        - more EG fixes: the level could sometimes go below zero and cause
150          noises or crashes
151        - minor fix of EGDecay (patch by Toshi Nagata)
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:
187        - fixed crash occurring on certain LSCP scripts (Bug 39)
188        - another thread safety fix for lscp "load engine" and "set
189          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    
207      * test cases:
208        - updated and fixed (haven't been touched in a while)
