2    
3      * audio driver:
4        - removed the nonsense audio channel constraint (which was hard coded to
5          max. 100 audio channels) for most audio drivers
6    
7    Version 0.5.1 (6 December 2007)
8    
9      * packaging changes:
10        - added autoconf checks for pthread library
11        - added autoconf check for pthread bug found on certain NPTL-enabled
12          glibc versions (see Gentoo bug report #194076)
13        - added autoconf checks for MS Windows
14    
15      * general changes:
16        - bugfix: the thread used by an editor plugin didn't die when the
17          editor closed
18        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
19          out all the space. operator--() did not apply size_mask after
20          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
21          order to avoid problems with the _NonVolatileReader functions.
22        - bugfix: Stream.h: added a missing divide by BytesPerSample in
23          GetWriteSpace(). Since this function is currently only used in
24          the stream's qsort() compare function, it didn't trigger any
25          bugs.
26        - Resampler.h, Synthesizer.h: cubic interpolation now works in
27          24bit mode too. Faster method to read 24bit words on little
28          endian machines (x86): replaced 3 byte reads + shifts with a 1
29          unaligned 32bit read and shift
30        - experimental support for MS Windows (MIDI input via MME, AUDIO
31          output via ASIO)
32        - made handling of SIGINT signal (Ctrl-C) a bit more robust
33        - support for monitoring the total number of active disk streams
34          (new LSCP commands: GET TOTAL_STREAM_COUNT,
35          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
36    
37      * AUDIO driver:
38        - added Windows ASIO low latency audio driver
39    
40      * MIDI driver:
41        - added MME Windows MIDI driver
42    
43      * LSCP server:
44        - added support for Windows style path / filenames, however with
45          forward slash path separators instead of backslash
46          (i.e. "C:/foo/bar.gig")
47        - allow naughty liblscp to send non-string device parameters within
48          apostrophes as well
49        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
50          "LIST FILE INSTRUMENTS <file>" and
51          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
52          about an arbitrary instrument file on the system where the sampler is
53          running on
54    
55    Version 0.5.0 (15 October 2007)
56    
57      * packaging changes:
58        - config.h is not going to be installed along with liblinuxsampler's
59          API header files anymore
60        - only the API relevant header (and source) files will be exported to
61          the Doxygen API documentation (explicitly listed in Doxyfile.in)
62        - added completely new XCode project files for Mac OSX which is now
63          capable to execute our autoconf environment, thus no need anymore
64          to maintain the compile time configuration file (osx/version.h) for
65          OSX manually (patch by Toshi Nagata)
66        - fixed buggy boolean --enable-foo / --disable-foo configure script
67          parameters
68        - global.h now only covers global definitions that are needed for the
69          C++ API header files, all implementation internal global definitions
70          are now in global_private.h
71        - atomic.h is not exposed to the C++ API anymore
72        - no need to include config.h anymore for using LS's API header files
73        - fixed warnings in API doc generation
74

89          MIDI instrument maps and assign each sampler channel individually
90          a certain map, so that i.e. separation of normal instruments and
91          drumkits is possible
92        - new notification events for tracking changes to audio/MIDI devices,
93          MIDI instrument maps, MIDI instruments, FX sends, global volume.
94        - sampler was limited to load max. 200 instruments in the background
95          due to a constant size RingBuffer FIFO which is now replaced by a
96          dynamic (unlimited) size std::list FIFO
97        - added FX sends, these allow to route audio signals to arbitrary audio
98          output channels for being processed by external effect processors
99          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
100          controllers
101        - global (sampler wide) volume can now be controlled at runtime
102        - Implemented new, improved notification system
103        - fixed compilation errors regarding OSX
104          (patch by Toshi Nagata)
105        - implemented instruments database
106        - added support for escape sequences to the instruments database
107        - added highly experimental support for on-the-fly instrument editing
108          within the sampler's process (by using instrument editor plugins),
109          you'll notice the new "Registered instrument editors:" message on
110          startup, added a new LSCP command:
111          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
112          to spawn a matching instrument editor for the instrument on the
113          given sampler channel, the plugin path can be overridden at compile
114          time with ./configure --enable-plugin-dir=/some/dir
115        - added experimental code for synchronizing instrument editors hosted
116          in the sampler's process to safely edit instruments while playing
117          without a crash (hopefully) by either suspending single regions
118          wherever possible or if unavoidable whole engine(s)
119        - fixed several issues in fundamental "Thread" class: set scheduling
120          policy and priority on thread level, set a minimum stack size for
121          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
122          threads simply inherited properties of starting thread instead of
123          setting their own policy and priority
124        - minor fix in our automatic stack trace mechanism on crashes, the
125          main process did not wait for the stack trace process to finish
126          its output
127        - fixed some minor memory leaks
128        - reenabled assembly features support, at the moment only for
129          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
130        - minor assembly fix in x86 features detection (don't use the PIC
131          register, to avoid relocations in the text segment at runtime)
132        - POSIX callback functions of Thread.h are hidden
133    
134    * MIDI driver:    * MIDI driver:
135      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
136    
137      * audio driver:
138        - the ALSA audio output driver parameters now reflect the correct
139          parameter value ranges for the respective selected sound card
140          (patch by Till Wimmer, a bit fixed and extended)
141    
142    * Gigasampler format engine:    * Gigasampler format engine:
143      - 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
144        die when EG2 has finished (this fixes a problem with clicks and        die when EG2 has finished (this fixes a problem with clicks and
145        voice starvation for some gigs)        voice starvation for some gigs)
146        - playback is no longer disabled during instrument loading
147        - all notes playing on a channel that changes its instrument keep
148          playing with the old instrument until they get a note off
149          command
150        - EG fix: a release value of zero could cause noises or crash
151        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
152        - EG fine tuning: when attack is zero the EG starts at a level
153          above max sustain level, which means that there is a decay phase
154          even if sustain is 100%
155        - more EG fixes: the level could sometimes go below zero and cause
156          noises or crashes
157        - minor fix of EGDecay (patch by Toshi Nagata)
158        - fixed compiler error when --enable-override-filter-type was
159          supplied to the configure script (fixes #46)
160        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
161          instead of a fix value
162        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
163          127 (solo mode) only kill voices if the respective mode really
164          changed
165    
166      * LSCP server:
167        - fixed compile time error for old Bison versions
168          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
169        - parser now supports extended ASCII character set
170          (up to ASCII code 255, i.e. includes now umlauts and accents)
171        - filename arguments in LSCP commands now allow to use escape
172          sequences, that is directly literal as one of: \', \", \\, \n, \r,
173          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
174          code value like \xf2) (fixes bug #24)
175        - the following LSCP commands now also support escape sequences for at
176          least one of their text-based parameters (i.e. name, description):
177          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
178          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
179          "SET DB_INSTRUMENT_DIRECTORY NAME",
180          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
181          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
182          "FIND DB_INSTRUMENT_DIRECTORIES"
183        - returns verbose syntax errors (line and column where syntax error
184          occured, the unexpected character and the actually expected, possible
185          character(s), the latter only if less than 5 possibilities)
186        - made sure that LSCP syntax is not affected by gigedit locale
187          settings
188        - bugfix regarding strings parameter lists: all comma separated lists
189          of strings were treated as being one string containing commas
190          (fixes #57)
191    
192    * Bug fixes:    * Bug fixes:
193      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
194        - another thread safety fix for lscp "load engine" and "set
195          channel audio output device"
196        - fixed a crash which occurs when reassigning the same engine
197          on a sampler channel with connected MIDI device
198        - fixed a crash which occurs when changing the number of ports of a MIDI
199          device connected to a sampler channel to number less then or equal
200          to the index of the port to which the sampler channel is connected.
201        - The previous bindings were not been disconnected when altering
202          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
203          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
204        - The active stream/voice count statistic was incorrect.
205        - notification events were not been sent for some sampler
206          channel changes
207        - added default min and max values to restrict the number of allowed
208          audio output channels and MIDI input ports
209        - the connection to the PCM interface is now closed when destroying
210          an audio output device
211        - files with slash in their path or filename could not be loaded
212    
213      * test cases:
214        - updated and fixed (haven't been touched in a while)
215
