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        - fixes for audio drivers with varying buffer sizes
28    
29      * audio driver:
30        - removed the nonsense audio channel constraint (which was hard coded to
31          max. 100 audio channels) for most audio drivers
32        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
33          opposed to the LSCP specs
34        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
35          reflected the wrong value
36        - fixed a memory management bug in ASIO driver
37        - Makefile fix: JACK_CFLAGS wasn't used
38        - JACK: use jack_client_open instead of thedeprecated
39          jack_client_new
40    
41      * MIDI driver:
42        - added JACK MIDI driver
43        - dispatch bank select as ordinary CC as well, the user might seriously
44          want to (mis)use it for some purpose ("fixed" in all current MIDI
45          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
46    
47      * instruments database:
48        - avoid time consuming samples scanning when adding instruments
49          to the instruments database
50        - added support for handling lost files in the instruments database
51    
52      * Gigasampler format engine:
53        - fixed a memory leak that could happen when a channel was deleted
54          while notes were playing
55        - made it possible to load an instrument even if the audio thread
56          isn't running
57        - added partial support for the "Controller Triggered" MIDI rule,
58          enough for piano gigs with pedal noise samples
59        - minor fix: only mark FX sends as being modified if really the
60          respective FX send MIDI controller was used
61        - added support for GM global device volume SysEx message
62        - bugfix: notes triggered at position 0 in the audio buffer were
63          sometimes wrongly killed in the same buffer, causing no sound to
64          be played
65        - added support for chromatic / drumkit mode Roland GS Sysex message
66          which is usally used to switch a part between chromatic sounds and
67          drumkit sounds (as opposed to their common default setting of MIDI
68          part 10 being a drumkit part and all other ones chromatic parts), in
69          LS however one can switch between the first 16 MIDI instrument maps
70          defined for the sampler
71    
72      * LSCP server:
73        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
74          react on MIDI data arriving on certain sampler channels (so far only
75          Note-On and Note-Off events are sent via this LSCP event)
76        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
77          react on MIDI data arriving on certain MIDI input devices (so far only
78          Note-On and Note-Off events are sent via this LSCP event)
79        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
80          SET DB_INSTRUMENT FILE_PATH
81        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
82          was incorrect
83    
84    Version 0.5.1 (6 December 2007)
85    
86      * packaging changes:
87        - added autoconf checks for pthread library
88        - added autoconf check for pthread bug found on certain NPTL-enabled
89          glibc versions (see Gentoo bug report #194076)
90        - added autoconf checks for MS Windows
91    
92      * general changes:
93        - bugfix: the thread used by an editor plugin didn't die when the
94          editor closed
95        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
96          out all the space. operator--() did not apply size_mask after
97          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
98          order to avoid problems with the _NonVolatileReader functions.
99        - bugfix: Stream.h: added a missing divide by BytesPerSample in
100          GetWriteSpace(). Since this function is currently only used in
101          the stream's qsort() compare function, it didn't trigger any
102          bugs.
103        - Resampler.h, Synthesizer.h: cubic interpolation now works in
104          24bit mode too. Faster method to read 24bit words on little
105          endian machines (x86): replaced 3 byte reads + shifts with a 1
106          unaligned 32bit read and shift
107        - experimental support for MS Windows (MIDI input via MME, AUDIO
108          output via ASIO)
109        - made handling of SIGINT signal (Ctrl-C) a bit more robust
110        - support for monitoring the total number of active disk streams
111          (new LSCP commands: GET TOTAL_STREAM_COUNT,
112          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
113    
114      * AUDIO driver:
115        - added Windows ASIO low latency audio driver
116    
117      * MIDI driver:
118        - added MME Windows MIDI driver
119    
120      * LSCP server:
121        - added support for Windows style path / filenames, however with
122          forward slash path separators instead of backslash
123          (i.e. "C:/foo/bar.gig")
124        - allow naughty liblscp to send non-string device parameters within
125          apostrophes as well
126        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
127          "LIST FILE INSTRUMENTS <file>" and
128          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
129          about an arbitrary instrument file on the system where the sampler is
130          running on
131    
132    Version 0.5.0 (15 October 2007)
133    
134      * packaging changes:
135        - config.h is not going to be installed along with liblinuxsampler's
136          API header files anymore
137        - only the API relevant header (and source) files will be exported to
138          the Doxygen API documentation (explicitly listed in Doxyfile.in)
139        - added completely new XCode project files for Mac OSX which is now
140          capable to execute our autoconf environment, thus no need anymore
141          to maintain the compile time configuration file (osx/version.h) for
142          OSX manually (patch by Toshi Nagata)
143        - fixed buggy boolean --enable-foo / --disable-foo configure script
144          parameters
145        - global.h now only covers global definitions that are needed for the
146          C++ API header files, all implementation internal global definitions
147          are now in global_private.h
148        - atomic.h is not exposed to the C++ API anymore
149        - no need to include config.h anymore for using LS's API header files
150        - fixed warnings in API doc generation
151

179        - Implemented new, improved notification system
180        - fixed compilation errors regarding OSX
181          (patch by Toshi Nagata)
182        - implemented instruments database
183        - added support for escape sequences to the instruments database
184        - added highly experimental support for on-the-fly instrument editing
185          within the sampler's process (by using instrument editor plugins),
186          you'll notice the new "Registered instrument editors:" message on
187          startup, added a new LSCP command:
188          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
189          to spawn a matching instrument editor for the instrument on the
190          given sampler channel, the plugin path can be overridden at compile
191          time with ./configure --enable-plugin-dir=/some/dir
192        - added experimental code for synchronizing instrument editors hosted
193          in the sampler's process to safely edit instruments while playing
194          without a crash (hopefully) by either suspending single regions
195          wherever possible or if unavoidable whole engine(s)
196        - fixed several issues in fundamental "Thread" class: set scheduling
197          policy and priority on thread level, set a minimum stack size for
198          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
199          threads simply inherited properties of starting thread instead of
200          setting their own policy and priority
201        - minor fix in our automatic stack trace mechanism on crashes, the
202          main process did not wait for the stack trace process to finish
203          its output
204        - fixed some minor memory leaks
205        - reenabled assembly features support, at the moment only for
206          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
207        - minor assembly fix in x86 features detection (don't use the PIC
208          register, to avoid relocations in the text segment at runtime)
209        - POSIX callback functions of Thread.h are hidden
210    
211    * MIDI driver:    * MIDI driver:
212      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
213    
214      * audio driver:
215        - the ALSA audio output driver parameters now reflect the correct
216          parameter value ranges for the respective selected sound card
217          (patch by Till Wimmer, a bit fixed and extended)
218

227      - EG fix: a release value of zero could cause noises or crash      - EG fix: a release value of zero could cause noises or crash
228      - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)      - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
229        - EG fine tuning: when attack is zero the EG starts at a level
230          above max sustain level, which means that there is a decay phase
231          even if sustain is 100%
232        - more EG fixes: the level could sometimes go below zero and cause
233          noises or crashes
234        - minor fix of EGDecay (patch by Toshi Nagata)
235        - fixed compiler error when --enable-override-filter-type was
236          supplied to the configure script (fixes #46)
237        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
238          instead of a fix value
239        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
240          127 (solo mode) only kill voices if the respective mode really
241          changed
242    
243      * LSCP server:
244        - fixed compile time error for old Bison versions
245          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
246        - parser now supports extended ASCII character set
247          (up to ASCII code 255, i.e. includes now umlauts and accents)
248        - filename arguments in LSCP commands now allow to use escape
249          sequences, that is directly literal as one of: \', \", \\, \n, \r,
250          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
251          code value like \xf2) (fixes bug #24)
252        - the following LSCP commands now also support escape sequences for at
253          least one of their text-based parameters (i.e. name, description):
254          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
255          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
256          "SET DB_INSTRUMENT_DIRECTORY NAME",
257          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
258          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
259          "FIND DB_INSTRUMENT_DIRECTORIES"
260        - returns verbose syntax errors (line and column where syntax error
261          occured, the unexpected character and the actually expected, possible
262          character(s), the latter only if less than 5 possibilities)
263        - made sure that LSCP syntax is not affected by gigedit locale
264          settings
265        - bugfix regarding strings parameter lists: all comma separated lists
266          of strings were treated as being one string containing commas
267          (fixes #57)
268    
269    * Bug fixes:    * Bug fixes:
270      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
271      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
272        channel audio output device"        channel audio output device"
273        - fixed a crash which occurs when reassigning the same engine
274          on a sampler channel with connected MIDI device
275        - fixed a crash which occurs when changing the number of ports of a MIDI
276          device connected to a sampler channel to number less then or equal
277          to the index of the port to which the sampler channel is connected.
278        - The previous bindings were not been disconnected when altering
279          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
280          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
281        - The active stream/voice count statistic was incorrect.
282        - notification events were not been sent for some sampler
283          channel changes
284        - added default min and max values to restrict the number of allowed
285          audio output channels and MIDI input ports
286        - the connection to the PCM interface is now closed when destroying
287          an audio output device
288        - files with slash in their path or filename could not be loaded
289    
290      * test cases:
291        - updated and fixed (haven't been touched in a while)
292
