# Line 1  Line 1 
1  Version CVS HEAD (?)  Version CVS HEAD (?)
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    
28      * AUDIO driver:
29        - added Windows ASIO low latency audio driver
30    
31      * MIDI driver:
32        - added MME Windows MIDI driver
33    
34      * LSCP server:
35        - added support for Windows style path / filenames, however with
36          forward slash path separators instead of backslash
37          (i.e. "C:/foo/bar.gig")
38        - allow naughty liblscp to send non-string device parameters within
39          apostrophes as well
40        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
41          "LIST FILE INSTRUMENTS <file>" and
42          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
43          about an arbitrary instrument file on the system where the sampler is
44          running on
45    
46    Version 0.5.0 (15 October 2007)
47    
48      * packaging changes:
49        - config.h is not going to be installed along with liblinuxsampler's
50          API header files anymore
51        - only the API relevant header (and source) files will be exported to
52          the Doxygen API documentation (explicitly listed in Doxyfile.in)
53        - added completely new XCode project files for Mac OSX which is now
54          capable to execute our autoconf environment, thus no need anymore
55          to maintain the compile time configuration file (osx/version.h) for
56          OSX manually (patch by Toshi Nagata)
57        - fixed buggy boolean --enable-foo / --disable-foo configure script
58          parameters
59        - global.h now only covers global definitions that are needed for the
60          C++ API header files, all implementation internal global definitions
61          are now in global_private.h
62        - atomic.h is not exposed to the C++ API anymore
63        - no need to include config.h anymore for using LS's API header files
64        - fixed warnings in API doc generation
65    
66      * general changes:
67        - replaced the old, confusing MIDI program change mechanism by a
68          flexible MIDI instrument mapper which allows to map arbitrary
69          (MIDI bank, MIDI program) pairs with arbitrary
70          (engine type, instrument file, file index) triplets which will be
71          loaded on the respective channel when such MIDI program change
72          messages arrive, beside that, each entry allows to define a life-time
73          strategy for the instrument, so the user can define whether the
74          instrument should i.e. be permanently loaded (to be able to switch
75          quickly among sounds) or i.e. loaded just on demand when the
76          respective program change arrives (to safe RAM space), as well as a
77          global volume factor for each entry, so the user can adjust the volume
78          dynamic of his mapped instrument collection without having to modify
79          the instrument files, also one can manage arbitrary amount of such
80          MIDI instrument maps and assign each sampler channel individually
81          a certain map, so that i.e. separation of normal instruments and
82          drumkits is possible
83        - new notification events for tracking changes to audio/MIDI devices,
84          MIDI instrument maps, MIDI instruments, FX sends, global volume.
85        - sampler was limited to load max. 200 instruments in the background
86          due to a constant size RingBuffer FIFO which is now replaced by a
87          dynamic (unlimited) size std::list FIFO
88        - added FX sends, these allow to route audio signals to arbitrary audio
89          output channels for being processed by external effect processors
90          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
91          controllers
92        - global (sampler wide) volume can now be controlled at runtime
93        - Implemented new, improved notification system
94        - fixed compilation errors regarding OSX
95          (patch by Toshi Nagata)
96        - implemented instruments database
97        - added support for escape sequences to the instruments database
98        - added highly experimental support for on-the-fly instrument editing
99          within the sampler's process (by using instrument editor plugins),
100          you'll notice the new "Registered instrument editors:" message on
101          startup, added a new LSCP command:
102          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
103          to spawn a matching instrument editor for the instrument on the
104          given sampler channel, the plugin path can be overridden at compile
105          time with ./configure --enable-plugin-dir=/some/dir
106        - added experimental code for synchronizing instrument editors hosted
107          in the sampler's process to safely edit instruments while playing
108          without a crash (hopefully) by either suspending single regions
109          wherever possible or if unavoidable whole engine(s)
110        - fixed several issues in fundamental "Thread" class: set scheduling
111          policy and priority on thread level, set a minimum stack size for
112          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
113          threads simply inherited properties of starting thread instead of
114          setting their own policy and priority
115        - minor fix in our automatic stack trace mechanism on crashes, the
116          main process did not wait for the stack trace process to finish
117          its output
118        - fixed some minor memory leaks
119        - reenabled assembly features support, at the moment only for
120          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
121        - minor assembly fix in x86 features detection (don't use the PIC
122          register, to avoid relocations in the text segment at runtime)
123        - POSIX callback functions of Thread.h are hidden
124    
125      * MIDI driver:
126        - dispatch bank select (MSB and LSB) messages
127    
128      * audio driver:
129        - the ALSA audio output driver parameters now reflect the correct
130          parameter value ranges for the respective selected sound card
131          (patch by Till Wimmer, a bit fixed and extended)
132    
133      * Gigasampler format engine:
134        - if a filter is used and EG2 finishes before EG1, let the voice
135          die when EG2 has finished (this fixes a problem with clicks and
136          voice starvation for some gigs)
137        - playback is no longer disabled during instrument loading
138        - all notes playing on a channel that changes its instrument keep
139          playing with the old instrument until they get a note off
140          command
141        - EG fix: a release value of zero could cause noises or crash
142        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
143        - EG fine tuning: when attack is zero the EG starts at a level
144          above max sustain level, which means that there is a decay phase
145          even if sustain is 100%
146        - more EG fixes: the level could sometimes go below zero and cause
147          noises or crashes
148        - minor fix of EGDecay (patch by Toshi Nagata)
149        - fixed compiler error when --enable-override-filter-type was
150          supplied to the configure script (fixes #46)
151        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
152          instead of a fix value
153        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
154          127 (solo mode) only kill voices if the respective mode really
155          changed
156    
157      * LSCP server:
158        - fixed compile time error for old Bison versions
159          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
160        - parser now supports extended ASCII character set
161          (up to ASCII code 255, i.e. includes now umlauts and accents)
162        - filename arguments in LSCP commands now allow to use escape
163          sequences, that is directly literal as one of: \', \", \\, \n, \r,
164          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
165          code value like \xf2) (fixes bug #24)
166        - the following LSCP commands now also support escape sequences for at
167          least one of their text-based parameters (i.e. name, description):
168          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
169          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
170          "SET DB_INSTRUMENT_DIRECTORY NAME",
171          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
172          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
173          "FIND DB_INSTRUMENT_DIRECTORIES"
174        - returns verbose syntax errors (line and column where syntax error
175          occured, the unexpected character and the actually expected, possible
176          character(s), the latter only if less than 5 possibilities)
177        - made sure that LSCP syntax is not affected by gigedit locale
178          settings
179        - bugfix regarding strings parameter lists: all comma separated lists
180          of strings were treated as being one string containing commas
181          (fixes #57)
182    
183      * Bug fixes:
184        - fixed crash occurring on certain LSCP scripts (Bug 39)
185        - another thread safety fix for lscp "load engine" and "set
186          channel audio output device"
187        - fixed a crash which occurs when reassigning the same engine
188          on a sampler channel with connected MIDI device
189        - fixed a crash which occurs when changing the number of ports of a MIDI
190          device connected to a sampler channel to number less then or equal
191          to the index of the port to which the sampler channel is connected.
192        - The previous bindings were not been disconnected when altering
193          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
194          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
195        - The active stream/voice count statistic was incorrect.
196        - notification events were not been sent for some sampler
197          channel changes
198        - added default min and max values to restrict the number of allowed
199          audio output channels and MIDI input ports
200        - the connection to the PCM interface is now closed when destroying
201          an audio output device
202        - files with slash in their path or filename could not be loaded
203    
204      * test cases:
205        - updated and fixed (haven't been touched in a while)
206
