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    
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        - experimental support for running LinuxSampler as a DSSI, LV2 and
29          VST plugin
30    
31      * audio driver:
32        - removed the nonsense audio channel constraint (which was hard coded to
33          max. 100 audio channels) for most audio drivers
34        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
35          opposed to the LSCP specs
36        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
37          reflected the wrong value
38        - fixed a memory management bug in ASIO driver
39        - Makefile fix: JACK_CFLAGS wasn't used
40        - JACK: use jack_client_open instead of the deprecated
41          jack_client_new
42    
43      * MIDI driver:
44        - added JACK MIDI driver
45        - dispatch bank select as ordinary CC as well, the user might seriously
46          want to (mis)use it for some purpose ("fixed" in all current MIDI
47          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
48    
49      * instruments database:
50        - avoid time consuming samples scanning when adding instruments
51          to the instruments database
52        - added support for handling lost files in the instruments database
53    
54      * Gigasampler format engine:
55        - fixed a memory leak that could happen when a channel was deleted
56          while notes were playing
57        - made it possible to load an instrument even if the audio thread
58          isn't running
59        - added partial support for the "Controller Triggered" MIDI rule,
60          enough for piano gigs with pedal noise samples
61        - minor fix: only mark FX sends as being modified if really the
62          respective FX send MIDI controller was used
63        - added support for GM global device volume SysEx message
64          (can be selected at compile time to either apply globally to the
65          whole sampler [default] or only to the sampler channels that are
66          connected to the respective MIDI input port the SysEx message arrived
67          on)
68        - bugfix: notes triggered at position 0 in the audio buffer were
69          sometimes wrongly killed in the same buffer, causing no sound to
70          be played
71        - added support for chromatic / drumkit mode Roland GS Sysex message
72          which is usally used to switch a part between chromatic sounds and
73          drumkit sounds (as opposed to their common default setting of MIDI
74          part 10 being a drumkit part and all other ones chromatic parts), in
75          LS however one can switch between the first 16 MIDI instrument maps
76          defined for the sampler
77        - made it possible to create multiple sample channels even if the
78          audio thread isn't running
79    
80      * LSCP server:
81        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
82          react on MIDI data arriving on certain sampler channels (so far only
83          Note-On and Note-Off events are sent via this LSCP event)
84        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
85          react on MIDI data arriving on certain MIDI input devices (so far only
86          Note-On and Note-Off events are sent via this LSCP event)
87        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
88          SET DB_INSTRUMENT FILE_PATH
89        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
90          frontends to send MIDI messages to specific sampler channel
91        - added two additional fields to GET FILE INSTRUMENT INFO command -
92          KEY_BINDINGS and KEYSWITCH_BINDINGS
93        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
94          was incorrect
95        - Optimized the retrieval of the MIDI instrument mappings
96    
97      * Bug fixes:
98        - fixed a crash which occurs when removing a sampler channel waiting
99          to start instrument loading after another channel
100    
101    
102    Version 0.5.1 (6 December 2007)
103    
104      * packaging changes:
105        - added autoconf checks for pthread library
106        - added autoconf check for pthread bug found on certain NPTL-enabled
107          glibc versions (see Gentoo bug report #194076)
108        - added autoconf checks for MS Windows
109    
110      * general changes:
111        - bugfix: the thread used by an editor plugin didn't die when the
112          editor closed
113        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
114          out all the space. operator--() did not apply size_mask after
115          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
116          order to avoid problems with the _NonVolatileReader functions.
117        - bugfix: Stream.h: added a missing divide by BytesPerSample in
118          GetWriteSpace(). Since this function is currently only used in
119          the stream's qsort() compare function, it didn't trigger any
120          bugs.
121        - Resampler.h, Synthesizer.h: cubic interpolation now works in
122          24bit mode too. Faster method to read 24bit words on little
123          endian machines (x86): replaced 3 byte reads + shifts with a 1
124          unaligned 32bit read and shift
125        - experimental support for MS Windows (MIDI input via MME, AUDIO
126          output via ASIO)
127        - made handling of SIGINT signal (Ctrl-C) a bit more robust
128        - support for monitoring the total number of active disk streams
129          (new LSCP commands: GET TOTAL_STREAM_COUNT,
130          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
131    
132      * AUDIO driver:
133        - added Windows ASIO low latency audio driver
134    
135      * MIDI driver:
136        - added MME Windows MIDI driver
137    
138      * LSCP server:
139        - added support for Windows style path / filenames, however with
140          forward slash path separators instead of backslash
141          (i.e. "C:/foo/bar.gig")
142        - allow naughty liblscp to send non-string device parameters within
143          apostrophes as well
144        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
145          "LIST FILE INSTRUMENTS <file>" and
146          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
147          about an arbitrary instrument file on the system where the sampler is
148          running on
149    
150    Version 0.5.0 (15 October 2007)
151    
152      * packaging changes:
153        - config.h is not going to be installed along with liblinuxsampler's
154          API header files anymore
155      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to
156        the Doxygen API documentation (explicitly listed in Doxyfile.in)        the Doxygen API documentation (explicitly listed in Doxyfile.in)
157        - added completely new XCode project files for Mac OSX which is now
158          capable to execute our autoconf environment, thus no need anymore
159          to maintain the compile time configuration file (osx/version.h) for
160          OSX manually (patch by Toshi Nagata)
161        - fixed buggy boolean --enable-foo / --disable-foo configure script
162          parameters
163        - global.h now only covers global definitions that are needed for the
164          C++ API header files, all implementation internal global definitions
165          are now in global_private.h
166        - atomic.h is not exposed to the C++ API anymore
167        - no need to include config.h anymore for using LS's API header files
168        - fixed warnings in API doc generation
169

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

250        - more EG fixes: the level could sometimes go below zero and cause
251          noises or crashes
252        - minor fix of EGDecay (patch by Toshi Nagata)
253        - fixed compiler error when --enable-override-filter-type was
254          supplied to the configure script (fixes #46)
255        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
256          instead of a fix value
257        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
258          127 (solo mode) only kill voices if the respective mode really
259          changed
260    
261      * LSCP server:
262        - fixed compile time error for old Bison versions
263          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
264        - parser now supports extended ASCII character set
265          (up to ASCII code 255, i.e. includes now umlauts and accents)
266        - filename arguments in LSCP commands now allow to use escape
267          sequences, that is directly literal as one of: \', \", \\, \n, \r,
268          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
269          code value like \xf2) (fixes bug #24)
270        - the following LSCP commands now also support escape sequences for at
271          least one of their text-based parameters (i.e. name, description):
272          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
273          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
274          "SET DB_INSTRUMENT_DIRECTORY NAME",
275          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
276          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
277          "FIND DB_INSTRUMENT_DIRECTORIES"
278        - returns verbose syntax errors (line and column where syntax error
279          occured, the unexpected character and the actually expected, possible
280          character(s), the latter only if less than 5 possibilities)
281        - made sure that LSCP syntax is not affected by gigedit locale
282          settings
283        - bugfix regarding strings parameter lists: all comma separated lists
284          of strings were treated as being one string containing commas
285          (fixes #57)
286    
287    * Bug fixes:    * Bug fixes:
288      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
289      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
290        channel audio output device"        channel audio output device"
291        - fixed a crash which occurs when reassigning the same engine
292          on a sampler channel with connected MIDI device
293        - fixed a crash which occurs when changing the number of ports of a MIDI
294          device connected to a sampler channel to number less then or equal
295          to the index of the port to which the sampler channel is connected.
296        - The previous bindings were not been disconnected when altering
297          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
298          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
299        - The active stream/voice count statistic was incorrect.
300        - notification events were not been sent for some sampler
301          channel changes
302        - added default min and max values to restrict the number of allowed
303          audio output channels and MIDI input ports
304        - the connection to the PCM interface is now closed when destroying
305          an audio output device
306        - files with slash in their path or filename could not be loaded
307    
308      * test cases:
309        - updated and fixed (haven't been touched in a while)
