2    
3    * general changes:    * general changes:
4        - bugfix: on some POSIX systems instrument editor plugins refused to
5          load as we used a non-portable Linux specific struct field
6          (fixes bug #70, patch by Ronald Baljeu)
7        - fixed endless loop which occured when loading an instrument editor
8          plugin DLL on Windows systems failed
9    
10      * audio driver:
11        - removed the nonsense audio channel constraint (which was hard coded to
12          max. 100 audio channels) for most audio drivers
13    
14      * instruments database
15        - avoid time consuming samples scanning when adding instruments
16          to the instruments database
17    
18    Version 0.5.1 (6 December 2007)
19    
20      * packaging changes:
21        - added autoconf checks for pthread library
22        - added autoconf check for pthread bug found on certain NPTL-enabled
23          glibc versions (see Gentoo bug report #194076)
24        - added autoconf checks for MS Windows
25    
26      * general changes:
27        - bugfix: the thread used by an editor plugin didn't die when the
28          editor closed
29        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
30          out all the space. operator--() did not apply size_mask after
31          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
32          order to avoid problems with the _NonVolatileReader functions.
33        - bugfix: Stream.h: added a missing divide by BytesPerSample in
34          GetWriteSpace(). Since this function is currently only used in
35          the stream's qsort() compare function, it didn't trigger any
36          bugs.
37        - Resampler.h, Synthesizer.h: cubic interpolation now works in
38          24bit mode too. Faster method to read 24bit words on little
39          endian machines (x86): replaced 3 byte reads + shifts with a 1
40          unaligned 32bit read and shift
41        - experimental support for MS Windows (MIDI input via MME, AUDIO
42          output via ASIO)
43        - made handling of SIGINT signal (Ctrl-C) a bit more robust
44        - support for monitoring the total number of active disk streams
45          (new LSCP commands: GET TOTAL_STREAM_COUNT,
46          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
47    
48      * AUDIO driver:
49        - added Windows ASIO low latency audio driver
50    
51      * MIDI driver:
52        - added MME Windows MIDI driver
53    
54      * LSCP server:
55        - added support for Windows style path / filenames, however with
56          forward slash path separators instead of backslash
57          (i.e. "C:/foo/bar.gig")
58        - allow naughty liblscp to send non-string device parameters within
59          apostrophes as well
60        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
61          "LIST FILE INSTRUMENTS <file>" and
62          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
63          about an arbitrary instrument file on the system where the sampler is
64          running on
65    
66    Version 0.5.0 (15 October 2007)
67    
68      * packaging changes:
69        - config.h is not going to be installed along with liblinuxsampler's
70          API header files anymore
71        - only the API relevant header (and source) files will be exported to
72          the Doxygen API documentation (explicitly listed in Doxyfile.in)
73        - added completely new XCode project files for Mac OSX which is now
74          capable to execute our autoconf environment, thus no need anymore
75          to maintain the compile time configuration file (osx/version.h) for
76          OSX manually (patch by Toshi Nagata)
77        - fixed buggy boolean --enable-foo / --disable-foo configure script
78          parameters
79        - global.h now only covers global definitions that are needed for the
80          C++ API header files, all implementation internal global definitions
81          are now in global_private.h
82        - atomic.h is not exposed to the C++ API anymore
83        - no need to include config.h anymore for using LS's API header files
84        - fixed warnings in API doc generation
85    
86      * general changes:
87      - replaced the old, confusing MIDI program change mechanism by a      - replaced the old, confusing MIDI program change mechanism by a

108        - added FX sends, these allow to route audio signals to arbitrary audio
109          output channels for being processed by external effect processors
110          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
111          controllers
112        - global (sampler wide) volume can now be controlled at runtime
113        - Implemented new, improved notification system
114        - fixed compilation errors regarding OSX
115          (patch by Toshi Nagata)
116        - implemented instruments database
117        - added support for escape sequences to the instruments database
118        - added highly experimental support for on-the-fly instrument editing
119          within the sampler's process (by using instrument editor plugins),
120          you'll notice the new "Registered instrument editors:" message on
121          startup, added a new LSCP command:
122          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
123          to spawn a matching instrument editor for the instrument on the
124          given sampler channel, the plugin path can be overridden at compile
125          time with ./configure --enable-plugin-dir=/some/dir
126        - added experimental code for synchronizing instrument editors hosted
127          in the sampler's process to safely edit instruments while playing
128          without a crash (hopefully) by either suspending single regions
129          wherever possible or if unavoidable whole engine(s)
130        - fixed several issues in fundamental "Thread" class: set scheduling
131          policy and priority on thread level, set a minimum stack size for
132          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
133          threads simply inherited properties of starting thread instead of
134          setting their own policy and priority
135        - minor fix in our automatic stack trace mechanism on crashes, the
136          main process did not wait for the stack trace process to finish
137          its output
138        - fixed some minor memory leaks
139        - reenabled assembly features support, at the moment only for
140          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
141        - minor assembly fix in x86 features detection (don't use the PIC
142          register, to avoid relocations in the text segment at runtime)
143        - POSIX callback functions of Thread.h are hidden
144    
145    * MIDI driver:    * MIDI driver:
146      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
147    
148      * audio driver:
149        - the ALSA audio output driver parameters now reflect the correct
150          parameter value ranges for the respective selected sound card
151          (patch by Till Wimmer, a bit fixed and extended)
152    
153    * Gigasampler format engine:    * Gigasampler format engine:
154      - 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
155        die when EG2 has finished (this fixes a problem with clicks and        die when EG2 has finished (this fixes a problem with clicks and
156        voice starvation for some gigs)        voice starvation for some gigs)
157        - playback is no longer disabled during instrument loading
158        - all notes playing on a channel that changes its instrument keep
159          playing with the old instrument until they get a note off
160          command
161        - EG fix: a release value of zero could cause noises or crash
162        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
163        - EG fine tuning: when attack is zero the EG starts at a level
164          above max sustain level, which means that there is a decay phase
165          even if sustain is 100%
166        - more EG fixes: the level could sometimes go below zero and cause
167          noises or crashes
168        - minor fix of EGDecay (patch by Toshi Nagata)
169        - fixed compiler error when --enable-override-filter-type was
170          supplied to the configure script (fixes #46)
171        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
172          instead of a fix value
173        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
174          127 (solo mode) only kill voices if the respective mode really
175          changed
176    
177      * LSCP server:
178        - fixed compile time error for old Bison versions
179          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
180        - parser now supports extended ASCII character set
181          (up to ASCII code 255, i.e. includes now umlauts and accents)
182        - filename arguments in LSCP commands now allow to use escape
183          sequences, that is directly literal as one of: \', \", \\, \n, \r,
184          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
185          code value like \xf2) (fixes bug #24)
186        - the following LSCP commands now also support escape sequences for at
187          least one of their text-based parameters (i.e. name, description):
188          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
189          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
190          "SET DB_INSTRUMENT_DIRECTORY NAME",
191          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
192          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
193          "FIND DB_INSTRUMENT_DIRECTORIES"
194        - returns verbose syntax errors (line and column where syntax error
195          occured, the unexpected character and the actually expected, possible
196          character(s), the latter only if less than 5 possibilities)
197        - made sure that LSCP syntax is not affected by gigedit locale
198          settings
199        - bugfix regarding strings parameter lists: all comma separated lists
200          of strings were treated as being one string containing commas
201          (fixes #57)
202    
203    * Bug fixes:    * Bug fixes:
204      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
205        - another thread safety fix for lscp "load engine" and "set
206          channel audio output device"
207        - fixed a crash which occurs when reassigning the same engine
208          on a sampler channel with connected MIDI device
209        - fixed a crash which occurs when changing the number of ports of a MIDI
210          device connected to a sampler channel to number less then or equal
211          to the index of the port to which the sampler channel is connected.
212        - The previous bindings were not been disconnected when altering
213          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
214          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
215        - The active stream/voice count statistic was incorrect.
216        - notification events were not been sent for some sampler
217          channel changes
218        - added default min and max values to restrict the number of allowed
219          audio output channels and MIDI input ports
220        - the connection to the PCM interface is now closed when destroying
221          an audio output device
222        - files with slash in their path or filename could not be loaded
223    
224      * test cases:
225        - updated and fixed (haven't been touched in a while)
226
