# Line 1  Line 1 
1  Version CVS HEAD (?)  Version CVS HEAD (?)
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    
8      * general changes:
9        - bugfix: the thread used by an editor plugin didn't die when the
10          editor closed
11        - bugfix: Ringbuffer.h:
12          fill_write_space_with_null() did not zero out all the space
13          operator--() did not apply size_mask after decrementing the read_ptr
14          DEFAULT_WRAP_ELEMENTS set to 0 in order to avoid problems with
15            the _NonVolatileReader functions.
16         - bugfix: Stream.h: added a missing divide by BytesPerSample in GetWriteSpace()
17           since this function is currently only used in the stream's
18           qsort() compare function, it didn't trigger any bugs
19         Resampler.h, Synthesizer.h:
20           cubic interpolation now works in 24bit mode too
21           faster method to read 24bit words on little endian machines (x86):
22           replaced 3 byte reads + shifts with a 1 unaligned 32bit read and shift
23    
24      * MIDI driver:
25        - added MME Windows MIDI driver
26    
27      * LSCP server:
28        - added support for Windows style path / filenames, however with
29          forward slash path separators instead of backslash
30          (i.e. "C:/foo/bar.gig")
31        - allow naughty liblscp to send non-string device parameters within
32          apostrophes as well
33    
34    Version 0.5.0 (15 October 2007)
35    
36      * packaging changes:
37        - config.h is not going to be installed along with liblinuxsampler's
38          API header files anymore
39        - only the API relevant header (and source) files will be exported to
40          the Doxygen API documentation (explicitly listed in Doxyfile.in)
41        - added completely new XCode project files for Mac OSX which is now
42          capable to execute our autoconf environment, thus no need anymore
43          to maintain the compile time configuration file (osx/version.h) for
44          OSX manually (patch by Toshi Nagata)
45        - fixed buggy boolean --enable-foo / --disable-foo configure script
46          parameters
47        - global.h now only covers global definitions that are needed for the
48          C++ API header files, all implementation internal global definitions
49          are now in global_private.h
50        - atomic.h is not exposed to the C++ API anymore
51        - no need to include config.h anymore for using LS's API header files
52        - fixed warnings in API doc generation
53

67        the instrument files        the instrument files, also one can manage arbitrary amount of such
68          MIDI instrument maps and assign each sampler channel individually
69          a certain map, so that i.e. separation of normal instruments and
70          drumkits is possible
71        - new notification events for tracking changes to audio/MIDI devices,
72          MIDI instrument maps, MIDI instruments, FX sends, global volume.
73        - sampler was limited to load max. 200 instruments in the background
74          due to a constant size RingBuffer FIFO which is now replaced by a
75          dynamic (unlimited) size std::list FIFO
76        - added FX sends, these allow to route audio signals to arbitrary audio
77          output channels for being processed by external effect processors
78          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
79          controllers
80        - global (sampler wide) volume can now be controlled at runtime
81        - Implemented new, improved notification system
82        - fixed compilation errors regarding OSX
83          (patch by Toshi Nagata)
84        - implemented instruments database
85        - added support for escape sequences to the instruments database
86        - added highly experimental support for on-the-fly instrument editing
87          within the sampler's process (by using instrument editor plugins),
88          you'll notice the new "Registered instrument editors:" message on
89          startup, added a new LSCP command:
90          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
91          to spawn a matching instrument editor for the instrument on the
92          given sampler channel, the plugin path can be overridden at compile
93          time with ./configure --enable-plugin-dir=/some/dir
94        - added experimental code for synchronizing instrument editors hosted
95          in the sampler's process to safely edit instruments while playing
96          without a crash (hopefully) by either suspending single regions
97          wherever possible or if unavoidable whole engine(s)
98        - fixed several issues in fundamental "Thread" class: set scheduling
99          policy and priority on thread level, set a minimum stack size for
100          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
101          threads simply inherited properties of starting thread instead of
102          setting their own policy and priority
103        - minor fix in our automatic stack trace mechanism on crashes, the
104          main process did not wait for the stack trace process to finish
105          its output
106        - fixed some minor memory leaks
107        - reenabled assembly features support, at the moment only for
108          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
109        - minor assembly fix in x86 features detection (don't use the PIC
110          register, to avoid relocations in the text segment at runtime)
111        - POSIX callback functions of Thread.h are hidden
112    
113    * MIDI driver:    * MIDI driver:
114      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
115    
116      * audio driver:
117        - the ALSA audio output driver parameters now reflect the correct
118          parameter value ranges for the respective selected sound card
119          (patch by Till Wimmer, a bit fixed and extended)
120    
121      * Gigasampler format engine:
122        - if a filter is used and EG2 finishes before EG1, let the voice
123          die when EG2 has finished (this fixes a problem with clicks and
124          voice starvation for some gigs)
125        - playback is no longer disabled during instrument loading
126        - all notes playing on a channel that changes its instrument keep
127          playing with the old instrument until they get a note off
128          command
129        - EG fix: a release value of zero could cause noises or crash
130        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
131        - EG fine tuning: when attack is zero the EG starts at a level
132          above max sustain level, which means that there is a decay phase
133          even if sustain is 100%
134        - more EG fixes: the level could sometimes go below zero and cause
135          noises or crashes
136        - minor fix of EGDecay (patch by Toshi Nagata)
137        - fixed compiler error when --enable-override-filter-type was
138          supplied to the configure script (fixes #46)
139        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
140          instead of a fix value
141        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
142          127 (solo mode) only kill voices if the respective mode really
143          changed
144    
145      * LSCP server:
146        - fixed compile time error for old Bison versions
147          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
148        - parser now supports extended ASCII character set
149          (up to ASCII code 255, i.e. includes now umlauts and accents)
150        - filename arguments in LSCP commands now allow to use escape
151          sequences, that is directly literal as one of: \', \", \\, \n, \r,
152          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
153          code value like \xf2) (fixes bug #24)
154        - the following LSCP commands now also support escape sequences for at
155          least one of their text-based parameters (i.e. name, description):
156          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
157          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
158          "SET DB_INSTRUMENT_DIRECTORY NAME",
159          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
160          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
161          "FIND DB_INSTRUMENT_DIRECTORIES"
162        - returns verbose syntax errors (line and column where syntax error
163          occured, the unexpected character and the actually expected, possible
164          character(s), the latter only if less than 5 possibilities)
165        - made sure that LSCP syntax is not affected by gigedit locale
166          settings
167        - bugfix regarding strings parameter lists: all comma separated lists
168          of strings were treated as being one string containing commas
169          (fixes #57)
170    
171      * Bug fixes:
172        - fixed crash occurring on certain LSCP scripts (Bug 39)
173        - another thread safety fix for lscp "load engine" and "set
174          channel audio output device"
175        - fixed a crash which occurs when reassigning the same engine
176          on a sampler channel with connected MIDI device
177        - fixed a crash which occurs when changing the number of ports of a MIDI
178          device connected to a sampler channel to number less then or equal
179          to the index of the port to which the sampler channel is connected.
180        - The previous bindings were not been disconnected when altering
181          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
182          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
183        - The active stream/voice count statistic was incorrect.
184        - notification events were not been sent for some sampler
185          channel changes
186        - added default min and max values to restrict the number of allowed
187          audio output channels and MIDI input ports
188        - the connection to the PCM interface is now closed when destroying
189          an audio output device
190        - files with slash in their path or filename could not be loaded
191    
192      * test cases:
193        - updated and fixed (haven't been touched in a while)
