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        - experimental support for running LinuxSampler as a DSSI, LV2 and
29          VST plugin
30        - notification events for stream/voice count statistics are now sent
31          only when there are actual changes
32        - added memory ordering constraints to improve stability on
33          multi-core and multi-cpu systems
34    
35      * audio driver:
36        - removed the nonsense audio channel constraint (which was hard coded to
37          max. 100 audio channels) for most audio drivers
38        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
39          opposed to the LSCP specs
40        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
41          reflected the wrong value
42        - fixed a memory management bug in ASIO driver
43        - Makefile fix: JACK_CFLAGS wasn't used
44        - JACK: use jack_client_open instead of the deprecated
45          jack_client_new
46    
47      * MIDI driver:
48        - added JACK MIDI driver
49        - dispatch bank select as ordinary CC as well, the user might seriously
50          want to (mis)use it for some purpose ("fixed" in all current MIDI
51          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
52    
53      * instruments database:
54        - avoid time consuming samples scanning when adding instruments
55          to the instruments database
56        - added support for handling lost files in the instruments database
57        - Implemented option for adding instruments in separate directories
58          in the instruments database
59          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
60    
61      * Gigasampler format engine:
62        - fixed a memory leak that could happen when a channel was deleted
63          while notes were playing
64        - made it possible to load an instrument even if the audio thread
65          isn't running
66        - added partial support for the "Controller Triggered" MIDI rule,
67          enough for piano gigs with pedal noise samples
68        - minor fix: only mark FX sends as being modified if really the
69          respective FX send MIDI controller was used
70        - added support for GM global device volume SysEx message
71          (can be selected at compile time to either apply globally to the
72          whole sampler [default] or only to the sampler channels that are
73          connected to the respective MIDI input port the SysEx message arrived
74          on)
75        - bugfix: notes triggered at position 0 in the audio buffer were
76          sometimes wrongly killed in the same buffer, causing no sound to
77          be played
78        - added support for chromatic / drumkit mode Roland GS Sysex message
79          which is usally used to switch a part between chromatic sounds and
80          drumkit sounds (as opposed to their common default setting of MIDI
81          part 10 being a drumkit part and all other ones chromatic parts), in
82          LS however one can switch between the first 16 MIDI instrument maps
83          defined for the sampler
84        - made it possible to create multiple sample channels even if the
85          audio thread isn't running
86    
87      * LSCP server:
88        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
89          react on MIDI data arriving on certain sampler channels (so far only
90          Note-On and Note-Off events are sent via this LSCP event)
91        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
92          react on MIDI data arriving on certain MIDI input devices (so far only
93          Note-On and Note-Off events are sent via this LSCP event)
94        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
95          SET DB_INSTRUMENT FILE_PATH
96        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
97          frontends to send MIDI messages to specific sampler channel
98        - added two additional fields to GET FILE INSTRUMENT INFO command -
99          KEY_BINDINGS and KEYSWITCH_BINDINGS
100        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
101          was incorrect
102        - Optimized the retrieval of the MIDI instrument mappings
103    
104      * Bug fixes:
105        - fixed a crash which occurs when removing a sampler channel waiting
106          to start instrument loading after another channel
107    
108    
109    Version 0.5.1 (6 December 2007)
110    
111      * packaging changes:
112        - added autoconf checks for pthread library
113        - added autoconf check for pthread bug found on certain NPTL-enabled
114          glibc versions (see Gentoo bug report #194076)
115        - added autoconf checks for MS Windows
116    
117      * general changes:
118        - bugfix: the thread used by an editor plugin didn't die when the
119          editor closed
120        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
121          out all the space. operator--() did not apply size_mask after
122          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
123          order to avoid problems with the _NonVolatileReader functions.
124        - bugfix: Stream.h: added a missing divide by BytesPerSample in
125          GetWriteSpace(). Since this function is currently only used in
126          the stream's qsort() compare function, it didn't trigger any
127          bugs.
128        - Resampler.h, Synthesizer.h: cubic interpolation now works in
129          24bit mode too. Faster method to read 24bit words on little
130          endian machines (x86): replaced 3 byte reads + shifts with a 1
131          unaligned 32bit read and shift
132        - experimental support for MS Windows (MIDI input via MME, AUDIO
133          output via ASIO)
134        - made handling of SIGINT signal (Ctrl-C) a bit more robust
135        - support for monitoring the total number of active disk streams
136          (new LSCP commands: GET TOTAL_STREAM_COUNT,
137          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
138    
139      * AUDIO driver:
140        - added Windows ASIO low latency audio driver
141    
142      * MIDI driver:
143        - added MME Windows MIDI driver
144    
145      * LSCP server:
146        - added support for Windows style path / filenames, however with
147          forward slash path separators instead of backslash
148          (i.e. "C:/foo/bar.gig")
149        - allow naughty liblscp to send non-string device parameters within
150          apostrophes as well
151        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
152          "LIST FILE INSTRUMENTS <file>" and
153          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
154          about an arbitrary instrument file on the system where the sampler is
155          running on
156    
157    Version 0.5.0 (15 October 2007)
158    
159      * packaging changes:
160        - config.h is not going to be installed along with liblinuxsampler's
161          API header files anymore
162        - only the API relevant header (and source) files will be exported to
163          the Doxygen API documentation (explicitly listed in Doxyfile.in)
164        - added completely new XCode project files for Mac OSX which is now
165          capable to execute our autoconf environment, thus no need anymore
166          to maintain the compile time configuration file (osx/version.h) for
167          OSX manually (patch by Toshi Nagata)
168        - fixed buggy boolean --enable-foo / --disable-foo configure script
169          parameters
170        - global.h now only covers global definitions that are needed for the
171          C++ API header files, all implementation internal global definitions
172          are now in global_private.h
173        - atomic.h is not exposed to the C++ API anymore
174        - no need to include config.h anymore for using LS's API header files
175        - fixed warnings in API doc generation
176

204        - Implemented new, improved notification system
205        - fixed compilation errors regarding OSX
206          (patch by Toshi Nagata)
207        - implemented instruments database
208        - added support for escape sequences to the instruments database
209        - added highly experimental support for on-the-fly instrument editing
210          within the sampler's process (by using instrument editor plugins),
211          you'll notice the new "Registered instrument editors:" message on
212          startup, added a new LSCP command:
213          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
214          to spawn a matching instrument editor for the instrument on the
215          given sampler channel, the plugin path can be overridden at compile
216          time with ./configure --enable-plugin-dir=/some/dir
217        - added experimental code for synchronizing instrument editors hosted
218          in the sampler's process to safely edit instruments while playing
219          without a crash (hopefully) by either suspending single regions
220          wherever possible or if unavoidable whole engine(s)
221        - fixed several issues in fundamental "Thread" class: set scheduling
222          policy and priority on thread level, set a minimum stack size for
223          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
224          threads simply inherited properties of starting thread instead of
225          setting their own policy and priority
226        - minor fix in our automatic stack trace mechanism on crashes, the
227          main process did not wait for the stack trace process to finish
228          its output
229        - fixed some minor memory leaks
230        - reenabled assembly features support, at the moment only for
231          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
232        - minor assembly fix in x86 features detection (don't use the PIC
233          register, to avoid relocations in the text segment at runtime)
234        - POSIX callback functions of Thread.h are hidden
235    
236    * MIDI driver:    * MIDI driver:
237      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
238    
239      * audio driver:
240        - the ALSA audio output driver parameters now reflect the correct
241          parameter value ranges for the respective selected sound card
242          (patch by Till Wimmer, a bit fixed and extended)

252      - EG fix: a release value of zero could cause noises or crash      - EG fix: a release value of zero could cause noises or crash
253        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
254        - EG fine tuning: when attack is zero the EG starts at a level
255          above max sustain level, which means that there is a decay phase
256          even if sustain is 100%
257        - more EG fixes: the level could sometimes go below zero and cause
258          noises or crashes
259        - minor fix of EGDecay (patch by Toshi Nagata)
260        - fixed compiler error when --enable-override-filter-type was
261          supplied to the configure script (fixes #46)
262        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
263          instead of a fix value
264        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
265          127 (solo mode) only kill voices if the respective mode really
266          changed
267    
268      * LSCP server:
269        - fixed compile time error for old Bison versions
270          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
271        - parser now supports extended ASCII character set
272          (up to ASCII code 255, i.e. includes now umlauts and accents)
273        - filename arguments in LSCP commands now allow to use escape
274          sequences, that is directly literal as one of: \', \", \\, \n, \r,
275          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
276          code value like \xf2) (fixes bug #24)
277        - the following LSCP commands now also support escape sequences for at
278          least one of their text-based parameters (i.e. name, description):
279          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
280          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
281          "SET DB_INSTRUMENT_DIRECTORY NAME",
282          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
283          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
284          "FIND DB_INSTRUMENT_DIRECTORIES"
285        - returns verbose syntax errors (line and column where syntax error
286          occured, the unexpected character and the actually expected, possible
287          character(s), the latter only if less than 5 possibilities)
288        - made sure that LSCP syntax is not affected by gigedit locale
289          settings
290        - bugfix regarding strings parameter lists: all comma separated lists
291          of strings were treated as being one string containing commas
292          (fixes #57)
293    
294    * Bug fixes:    * Bug fixes:
295      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
296      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
297        channel audio output device"        channel audio output device"
298        - fixed a crash which occurs when reassigning the same engine
299          on a sampler channel with connected MIDI device
300        - fixed a crash which occurs when changing the number of ports of a MIDI
301          device connected to a sampler channel to number less then or equal
302          to the index of the port to which the sampler channel is connected.
303        - The previous bindings were not been disconnected when altering
304          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
305          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
306        - The active stream/voice count statistic was incorrect.
307        - notification events were not been sent for some sampler
308          channel changes
309        - added default min and max values to restrict the number of allowed
310          audio output channels and MIDI input ports
311        - the connection to the PCM interface is now closed when destroying
312          an audio output device
313        - files with slash in their path or filename could not be loaded
314    
315      * test cases:
316        - updated and fixed (haven't been touched in a while)
