# Line 1  Line 1 
1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3      * packaging changes:
4        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5          causing e.g. the libgig test to fail when
6          "./configure --disable-jack-driver" was used
7          (patch by Alexis Ballier)
8        - fixed compilation with gcc 4.3
9    
10      * general changes:
11        - bugfix: on some POSIX systems instrument editor plugins refused to
12          load as we used a non-portable Linux specific struct field
13          (fixes bug #70, patch by Ronald Baljeu)
14        - fixed endless loop which occured when loading an instrument editor
15          plugin DLL on Windows systems failed
16        - fixed memory leaks that occurred when liblinuxsampler was unloaded
17        - optimized the SynchronizedConfig class so it doesn't wait
18          unnecessarily long after an update
19        - added support for notifying instrument editors on note-on / note-off
20          events (e.g. to highlight the pressed keys on the virtual keyboard
21          of gigedit)
22        - added support for triggering notes by instrument editors (see above)
23        - be verbose on DLL load errors (on Linux)
24        - fixed di-harmonic triangle LFO implementation (this LFO implementation
25          is only used by very few systems, most pick the int math
26          implementation, which is usually faster)
27    
28      * audio driver:
29        - removed the nonsense audio channel constraint (which was hard coded to
30          max. 100 audio channels) for most audio drivers
31        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
32          opposed to the LSCP specs
33        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
34          reflected the wrong value
35        - fixed a memory management bug in ASIO driver
36    
37      * MIDI driver:
38        - added JACK MIDI driver
39    
40      * instruments database:
41        - avoid time consuming samples scanning when adding instruments
42          to the instruments database
43    
44      * Gigasampler format engine:
45        - fixed a memory leak that could happen when a channel was deleted
46          while notes were playing
47        - made it possible to load an instrument even if the audio thread
48          isn't running
49        - added partial support for the "Controller Triggered" MIDI rule,
50          enough for piano gigs with pedal noise samples
51    
52      * LSCP server:
53        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
54          react on MIDI data arriving on certain sampler channels (so far only
55          Note-On and Note-Off events are sent via this LSCP event)
56        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
57          react on MIDI data arriving on certain MIDI input devices (so far only
58          Note-On and Note-Off events are sent via this LSCP event)
59    
60    Version 0.5.1 (6 December 2007)
61    
62      * packaging changes:
63        - added autoconf checks for pthread library
64        - added autoconf check for pthread bug found on certain NPTL-enabled
65          glibc versions (see Gentoo bug report #194076)
66        - added autoconf checks for MS Windows
67    
68      * general changes:
69        - bugfix: the thread used by an editor plugin didn't die when the
70          editor closed
71        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
72          out all the space. operator--() did not apply size_mask after
73          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
74          order to avoid problems with the _NonVolatileReader functions.
75        - bugfix: Stream.h: added a missing divide by BytesPerSample in
76          GetWriteSpace(). Since this function is currently only used in
77          the stream's qsort() compare function, it didn't trigger any
78          bugs.
79        - Resampler.h, Synthesizer.h: cubic interpolation now works in
80          24bit mode too. Faster method to read 24bit words on little
81          endian machines (x86): replaced 3 byte reads + shifts with a 1
82          unaligned 32bit read and shift
83        - experimental support for MS Windows (MIDI input via MME, AUDIO
84          output via ASIO)
85        - made handling of SIGINT signal (Ctrl-C) a bit more robust
86        - support for monitoring the total number of active disk streams
87          (new LSCP commands: GET TOTAL_STREAM_COUNT,
88          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
89    
90      * AUDIO driver:
91        - added Windows ASIO low latency audio driver
92    
93      * MIDI driver:
94        - added MME Windows MIDI driver
95    
96      * LSCP server:
97        - added support for Windows style path / filenames, however with
98          forward slash path separators instead of backslash
99          (i.e. "C:/foo/bar.gig")
100        - allow naughty liblscp to send non-string device parameters within
101          apostrophes as well
102        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
103          "LIST FILE INSTRUMENTS <file>" and
104          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
105          about an arbitrary instrument file on the system where the sampler is
106          running on
107    
108    Version 0.5.0 (15 October 2007)
109    
110      * packaging changes:
111        - config.h is not going to be installed along with liblinuxsampler's
112          API header files anymore
113        - only the API relevant header (and source) files will be exported to
114          the Doxygen API documentation (explicitly listed in Doxyfile.in)
115        - added completely new XCode project files for Mac OSX which is now
116          capable to execute our autoconf environment, thus no need anymore
117          to maintain the compile time configuration file (osx/version.h) for
118          OSX manually (patch by Toshi Nagata)
119        - fixed buggy boolean --enable-foo / --disable-foo configure script
120          parameters
121        - global.h now only covers global definitions that are needed for the
122          C++ API header files, all implementation internal global definitions
123          are now in global_private.h
124        - atomic.h is not exposed to the C++ API anymore
125        - no need to include config.h anymore for using LS's API header files
126        - fixed warnings in API doc generation

155        - Implemented new, improved notification system
156        - fixed compilation errors regarding OSX
157          (patch by Toshi Nagata)
158        - implemented instruments database
159        - added support for escape sequences to the instruments database
160        - added highly experimental support for on-the-fly instrument editing
161          within the sampler's process (by using instrument editor plugins),
162          you'll notice the new "Registered instrument editors:" message on
163          startup, added a new LSCP command:
164          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
165          to spawn a matching instrument editor for the instrument on the
166          given sampler channel, the plugin path can be overridden at compile
167          time with ./configure --enable-plugin-dir=/some/dir
168        - added experimental code for synchronizing instrument editors hosted
169          in the sampler's process to safely edit instruments while playing
170          without a crash (hopefully) by either suspending single regions
171          wherever possible or if unavoidable whole engine(s)
172        - fixed several issues in fundamental "Thread" class: set scheduling
173          policy and priority on thread level, set a minimum stack size for
174          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
175          threads simply inherited properties of starting thread instead of
176          setting their own policy and priority
177        - minor fix in our automatic stack trace mechanism on crashes, the
178          main process did not wait for the stack trace process to finish
179          its output
180        - fixed some minor memory leaks
181        - reenabled assembly features support, at the moment only for
182          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
183        - minor assembly fix in x86 features detection (don't use the PIC
184          register, to avoid relocations in the text segment at runtime)
185        - POSIX callback functions of Thread.h are hidden
186    
187    * MIDI driver:    * MIDI driver:
188      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
189    
190      * audio driver:
191        - the ALSA audio output driver parameters now reflect the correct
192          parameter value ranges for the respective selected sound card
193          (patch by Till Wimmer, a bit fixed and extended)
194

208        - more EG fixes: the level could sometimes go below zero and cause
209          noises or crashes
210        - minor fix of EGDecay (patch by Toshi Nagata)
211        - fixed compiler error when --enable-override-filter-type was
212          supplied to the configure script (fixes #46)
213        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
214          instead of a fix value
215        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
216          127 (solo mode) only kill voices if the respective mode really
217          changed
218    
219      * LSCP server:
220        - fixed compile time error for old Bison versions
221          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
222        - parser now supports extended ASCII character set
223          (up to ASCII code 255, i.e. includes now umlauts and accents)
224        - filename arguments in LSCP commands now allow to use escape
225          sequences, that is directly literal as one of: \', \", \\, \n, \r,
226          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
227          code value like \xf2) (fixes bug #24)
228        - the following LSCP commands now also support escape sequences for at
229          least one of their text-based parameters (i.e. name, description):
230          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
231          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
232          "SET DB_INSTRUMENT_DIRECTORY NAME",
233          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
234          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
235          "FIND DB_INSTRUMENT_DIRECTORIES"
236        - returns verbose syntax errors (line and column where syntax error
237          occured, the unexpected character and the actually expected, possible
238          character(s), the latter only if less than 5 possibilities)
239        - made sure that LSCP syntax is not affected by gigedit locale
240          settings
241        - bugfix regarding strings parameter lists: all comma separated lists
242          of strings were treated as being one string containing commas
243          (fixes #57)
244    
245    * Bug fixes:    * Bug fixes:
246      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)

248        channel audio output device"        channel audio output device"
249        - fixed a crash which occurs when reassigning the same engine
250          on a sampler channel with connected MIDI device
251        - fixed a crash which occurs when changing the number of ports of a MIDI
252          device connected to a sampler channel to number less then or equal
253          to the index of the port to which the sampler channel is connected.
254        - The previous bindings were not been disconnected when altering
255          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
256          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
257        - The active stream/voice count statistic was incorrect.
258        - notification events were not been sent for some sampler
259          channel changes
260        - added default min and max values to restrict the number of allowed
261          audio output channels and MIDI input ports
262        - the connection to the PCM interface is now closed when destroying
263          an audio output device
264        - files with slash in their path or filename could not be loaded
265
