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

153        - global (sampler wide) volume can now be controlled at runtime
154        - Implemented new, improved notification system
155        - fixed compilation errors regarding OSX
156          (patch by Toshi Nagata)
157        - implemented instruments database
158        - added support for escape sequences to the instruments database
159        - added highly experimental support for on-the-fly instrument editing
160          within the sampler's process (by using instrument editor plugins),
161          you'll notice the new "Registered instrument editors:" message on
162          startup, added a new LSCP command:
163          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
164          to spawn a matching instrument editor for the instrument on the
165          given sampler channel, the plugin path can be overridden at compile
166          time with ./configure --enable-plugin-dir=/some/dir
167        - added experimental code for synchronizing instrument editors hosted
168          in the sampler's process to safely edit instruments while playing
169          without a crash (hopefully) by either suspending single regions
170          wherever possible or if unavoidable whole engine(s)
171        - fixed several issues in fundamental "Thread" class: set scheduling
172          policy and priority on thread level, set a minimum stack size for
173          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
174          threads simply inherited properties of starting thread instead of
175          setting their own policy and priority
176        - minor fix in our automatic stack trace mechanism on crashes, the
177          main process did not wait for the stack trace process to finish
178          its output
179        - fixed some minor memory leaks
180        - reenabled assembly features support, at the moment only for
181          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
182        - minor assembly fix in x86 features detection (don't use the PIC
183          register, to avoid relocations in the text segment at runtime)
184        - POSIX callback functions of Thread.h are hidden
185    
186    * MIDI driver:    * MIDI driver:
187      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
188    
189      * audio driver:
190        - the ALSA audio output driver parameters now reflect the correct
191          parameter value ranges for the respective selected sound card
192          (patch by Till Wimmer, a bit fixed and extended)
193    
194    * Gigasampler format engine:    * Gigasampler format engine:
195      - 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
196        die when EG2 has finished (this fixes a problem with clicks and        die when EG2 has finished (this fixes a problem with clicks and
197        voice starvation for some gigs)        voice starvation for some gigs)
198        - playback is no longer disabled during instrument loading
199        - all notes playing on a channel that changes its instrument keep
200          playing with the old instrument until they get a note off
201          command
202        - EG fix: a release value of zero could cause noises or crash
203        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
204        - EG fine tuning: when attack is zero the EG starts at a level
205          above max sustain level, which means that there is a decay phase
206          even if sustain is 100%
207        - more EG fixes: the level could sometimes go below zero and cause
208          noises or crashes
209        - minor fix of EGDecay (patch by Toshi Nagata)
210        - fixed compiler error when --enable-override-filter-type was
211          supplied to the configure script (fixes #46)
212        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
213          instead of a fix value
214        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
215          127 (solo mode) only kill voices if the respective mode really
216          changed
217    
218      * LSCP server:
219        - fixed compile time error for old Bison versions
220          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
221        - parser now supports extended ASCII character set
222          (up to ASCII code 255, i.e. includes now umlauts and accents)
223        - filename arguments in LSCP commands now allow to use escape
224          sequences, that is directly literal as one of: \', \", \\, \n, \r,
225          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
226          code value like \xf2) (fixes bug #24)
227        - the following LSCP commands now also support escape sequences for at
228          least one of their text-based parameters (i.e. name, description):
229          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
230          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
231          "SET DB_INSTRUMENT_DIRECTORY NAME",
232          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
233          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
234          "FIND DB_INSTRUMENT_DIRECTORIES"
235        - returns verbose syntax errors (line and column where syntax error
236          occured, the unexpected character and the actually expected, possible
237          character(s), the latter only if less than 5 possibilities)
238        - made sure that LSCP syntax is not affected by gigedit locale
239          settings
240        - bugfix regarding strings parameter lists: all comma separated lists
241          of strings were treated as being one string containing commas
242          (fixes #57)
243    
244    * Bug fixes:    * Bug fixes:
245      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
246        - another thread safety fix for lscp "load engine" and "set
247          channel audio output device"
248        - fixed a crash which occurs when reassigning the same engine
249          on a sampler channel with connected MIDI device
250        - fixed a crash which occurs when changing the number of ports of a MIDI
251          device connected to a sampler channel to number less then or equal
252          to the index of the port to which the sampler channel is connected.
253        - The previous bindings were not been disconnected when altering
254          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
255          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
256        - The active stream/voice count statistic was incorrect.
257        - notification events were not been sent for some sampler
258          channel changes
259        - added default min and max values to restrict the number of allowed
260          audio output channels and MIDI input ports
261        - the connection to the PCM interface is now closed when destroying
262          an audio output device
263        - files with slash in their path or filename could not be loaded
264    
265      * test cases:
266        - updated and fixed (haven't been touched in a while)
267
