1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3    * packaging changes:    * 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        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10    
11      * general changes:
12        - bugfix: on some POSIX systems instrument editor plugins refused to
13          load as we used a non-portable Linux specific struct field
14          (fixes bug #70, patch by Ronald Baljeu)
15        - fixed endless loop which occured when loading an instrument editor
16          plugin DLL on Windows systems failed
17        - fixed memory leaks that occurred when liblinuxsampler was unloaded
18        - optimized the SynchronizedConfig class so it doesn't wait
19          unnecessarily long after an update
20        - added support for notifying instrument editors on note-on / note-off
21          events (e.g. to highlight the pressed keys on the virtual keyboard
22          of gigedit)
23        - added support for triggering notes by instrument editors (see above)
24        - be verbose on DLL load errors (on Linux)
25        - fixed di-harmonic triangle LFO implementation (this LFO implementation
26          is only used by very few systems, most pick the int math
27          implementation, which is usually faster)
28        - fixes for audio drivers with varying buffer sizes
29        - experimental support for running LinuxSampler as a DSSI, LV2 and
30          VST plugin
31        - notification events for stream/voice count statistics are now sent
32          only when there are actual changes
33        - added memory ordering constraints to improve stability on
34          multi-core and multi-cpu systems
35    
36      * audio driver:
37        - removed the nonsense audio channel constraint (which was hard coded to
38          max. 100 audio channels) for most audio drivers
39        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
40          opposed to the LSCP specs
41        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
42          reflected the wrong value
43        - fixed a memory management bug in ASIO driver
44        - Makefile fix: JACK_CFLAGS wasn't used
45        - JACK: use jack_client_open instead of the deprecated
46          jack_client_new
47    
48      * MIDI driver:
49        - added JACK MIDI driver
50        - dispatch bank select as ordinary CC as well, the user might seriously
51          want to (mis)use it for some purpose ("fixed" in all current MIDI
52          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
53    
54      * instruments database:
55        - avoid time consuming samples scanning when adding instruments
56          to the instruments database
57        - added support for handling lost files in the instruments database
58        - Implemented option for adding instruments in separate directories
59          in the instruments database
60          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
61    
62      * Gigasampler format engine:
63        - fixed a memory leak that could happen when a channel was deleted
64          while notes were playing
65        - made it possible to load an instrument even if the audio thread
66          isn't running
67        - added partial support for the "Controller Triggered" MIDI rule,
68          enough for piano gigs with pedal noise samples
69        - minor fix: only mark FX sends as being modified if really the
70          respective FX send MIDI controller was used
71        - added support for GM global device volume SysEx message
72          (can be selected at compile time to either apply globally to the
73          whole sampler [default] or only to the sampler channels that are
74          connected to the respective MIDI input port the SysEx message arrived
75          on)
76        - bugfix: notes triggered at position 0 in the audio buffer were
77          sometimes wrongly killed in the same buffer, causing no sound to
78          be played
79        - added support for chromatic / drumkit mode Roland GS Sysex message
80          which is usally used to switch a part between chromatic sounds and
81          drumkit sounds (as opposed to their common default setting of MIDI
82          part 10 being a drumkit part and all other ones chromatic parts), in
83          LS however one can switch between the first 16 MIDI instrument maps
84          defined for the sampler
85        - made it possible to create multiple sample channels even if the
86          audio thread isn't running
87    
88      * LSCP server:
89        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
90          react on MIDI data arriving on certain sampler channels (so far only
91          Note-On and Note-Off events are sent via this LSCP event)
92        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
93          react on MIDI data arriving on certain MIDI input devices (so far only
94          Note-On and Note-Off events are sent via this LSCP event)
95        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
96          SET DB_INSTRUMENT FILE_PATH
97        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
98          frontends to send MIDI messages to specific sampler channel
99        - added two additional fields to GET FILE INSTRUMENT INFO command -
100          KEY_BINDINGS and KEYSWITCH_BINDINGS
101        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
102          was incorrect
103        - Optimized the retrieval of the MIDI instrument mappings
104    
105      * Bug fixes:
106        - fixed a crash which occurs when removing a sampler channel waiting
107          to start instrument loading after another channel
108    
109    
110    Version 0.5.1 (6 December 2007)
111    
112      * packaging changes:
113        - added autoconf checks for pthread library
114        - added autoconf check for pthread bug found on certain NPTL-enabled
115          glibc versions (see Gentoo bug report #194076)
116        - added autoconf checks for MS Windows
117    
118      * general changes:
119        - bugfix: the thread used by an editor plugin didn't die when the
120          editor closed
121        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
122          out all the space. operator--() did not apply size_mask after
123          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
124          order to avoid problems with the _NonVolatileReader functions.
125        - bugfix: Stream.h: added a missing divide by BytesPerSample in
126          GetWriteSpace(). Since this function is currently only used in
127          the stream's qsort() compare function, it didn't trigger any
128          bugs.
129        - Resampler.h, Synthesizer.h: cubic interpolation now works in
130          24bit mode too. Faster method to read 24bit words on little
131          endian machines (x86): replaced 3 byte reads + shifts with a 1
132          unaligned 32bit read and shift
133        - experimental support for MS Windows (MIDI input via MME, AUDIO
134          output via ASIO)
135        - made handling of SIGINT signal (Ctrl-C) a bit more robust
136        - support for monitoring the total number of active disk streams
137          (new LSCP commands: GET TOTAL_STREAM_COUNT,
138          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
139    
140      * AUDIO driver:
141        - added Windows ASIO low latency audio driver
142    
143      * MIDI driver:
144        - added MME Windows MIDI driver
145    
146      * LSCP server:
147        - added support for Windows style path / filenames, however with
148          forward slash path separators instead of backslash
149          (i.e. "C:/foo/bar.gig")
150        - allow naughty liblscp to send non-string device parameters within
151          apostrophes as well
152        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
153          "LIST FILE INSTRUMENTS <file>" and
154          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
155          about an arbitrary instrument file on the system where the sampler is
156          running on
157    
158    Version 0.5.0 (15 October 2007)
159    
160      * packaging changes:
161        - config.h is not going to be installed along with liblinuxsampler's
162          API header files anymore
163      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to

169        - fixed buggy boolean --enable-foo / --disable-foo configure script
170          parameters
171        - global.h now only covers global definitions that are needed for the
172          C++ API header files, all implementation internal global definitions
173          are now in global_private.h
174        - atomic.h is not exposed to the C++ API anymore
175        - no need to include config.h anymore for using LS's API header files
176        - fixed warnings in API doc generation

208      - implemented instruments database      - implemented instruments database
209        - added support for escape sequences to the instruments database
210        - added highly experimental support for on-the-fly instrument editing
211          within the sampler's process (by using instrument editor plugins),
212          you'll notice the new "Registered instrument editors:" message on
213          startup, added a new LSCP command:
214          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
215          to spawn a matching instrument editor for the instrument on the
216          given sampler channel, the plugin path can be overridden at compile
217          time with ./configure --enable-plugin-dir=/some/dir
218        - added experimental code for synchronizing instrument editors hosted
219          in the sampler's process to safely edit instruments while playing
220          without a crash (hopefully) by either suspending single regions
221          wherever possible or if unavoidable whole engine(s)
222        - fixed several issues in fundamental "Thread" class: set scheduling
223          policy and priority on thread level, set a minimum stack size for
224          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
225          threads simply inherited properties of starting thread instead of
226          setting their own policy and priority
227        - minor fix in our automatic stack trace mechanism on crashes, the
228          main process did not wait for the stack trace process to finish
229          its output
230        - fixed some minor memory leaks
231        - reenabled assembly features support, at the moment only for
232          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
233        - minor assembly fix in x86 features detection (don't use the PIC
234          register, to avoid relocations in the text segment at runtime)
235        - POSIX callback functions of Thread.h are hidden
236

261        - fixed compiler error when --enable-override-filter-type was
262          supplied to the configure script (fixes #46)
263        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
264          instead of a fix value
265        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
266          127 (solo mode) only kill voices if the respective mode really
267          changed
268    
269      * LSCP server:
270        - fixed compile time error for old Bison versions
271          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
272        - parser now supports extended ASCII character set
273          (up to ASCII code 255, i.e. includes now umlauts and accents)
274        - filename arguments in LSCP commands now allow to use escape
275          sequences, that is directly literal as one of: \', \", \\, \n, \r,
276          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
277          code value like \xf2) (fixes bug #24)
278        - the following LSCP commands now also support escape sequences for at
279          least one of their text-based parameters (i.e. name, description):
280          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
281          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
282          "SET DB_INSTRUMENT_DIRECTORY NAME",
283          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
284          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
285          "FIND DB_INSTRUMENT_DIRECTORIES"
286        - returns verbose syntax errors (line and column where syntax error
287          occured, the unexpected character and the actually expected, possible
288          character(s), the latter only if less than 5 possibilities)
289        - made sure that LSCP syntax is not affected by gigedit locale
290          settings
291        - bugfix regarding strings parameter lists: all comma separated lists
292          of strings were treated as being one string containing commas
293          (fixes #57)
294    
295    * Bug fixes:    * Bug fixes:
296      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
297      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
298        channel audio output device"        channel audio output device"
299        - fixed a crash which occurs when reassigning the same engine
300          on a sampler channel with connected MIDI device
301        - fixed a crash which occurs when changing the number of ports of a MIDI
302          device connected to a sampler channel to number less then or equal
303          to the index of the port to which the sampler channel is connected.
304        - The previous bindings were not been disconnected when altering
305          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
306          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
307        - The active stream/voice count statistic was incorrect.
308        - notification events were not been sent for some sampler
309          channel changes
310        - added default min and max values to restrict the number of allowed
311          audio output channels and MIDI input ports
312        - the connection to the PCM interface is now closed when destroying
313          an audio output device
314        - files with slash in their path or filename could not be loaded
315    
316      * test cases:
317        - updated and fixed (haven't been touched in a while)
