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        - fixed configure so it detects x86_64 (#107)
11        - fixes for building with newer MinGW versions
12        - fix for building with bison 2.4 (#111)
13    
14      * general changes:
15        - bugfix: on some POSIX systems instrument editor plugins refused to
16          load as we used a non-portable Linux specific struct field
17          (fixes bug #70, patch by Ronald Baljeu)
18        - fixed endless loop which occured when loading an instrument editor
19          plugin DLL on Windows systems failed
20        - fixed memory leaks that occurred when liblinuxsampler was unloaded
21        - optimized the SynchronizedConfig class so it doesn't wait
22          unnecessarily long after an update
23        - added support for notifying instrument editors on note-on / note-off
24          events (e.g. to highlight the pressed keys on the virtual keyboard
25          of gigedit)
26        - added support for triggering notes by instrument editors (see above)
27        - be verbose on DLL load errors (on Linux)
28        - fixed di-harmonic triangle LFO implementation (this LFO implementation
29          is only used by very few systems, most pick the int math
30          implementation, which is usually faster)
31        - fixes for audio drivers with varying buffer sizes
32        - experimental support for running LinuxSampler as a DSSI, LV2 and
33          VST plugin
34        - notification events for stream/voice count statistics are now sent
35          only when there are actual changes
36        - added memory ordering constraints to improve stability on
37          multi-core and multi-cpu systems
38        - maximum voices and disk streams can now be altered at runtime
39        - fixed CPU feature detection on x86_64 (maybe fixes #108)
40        - automatic stacktrace mechanism is now turned off by default and can
41          be switched on by command line option "--stacktrace" (the automatic
42          stacktrace mechanism seems to be broken on most systems at the moment)
43    
44      * audio driver:
45        - removed the nonsense audio channel constraint (which was hard coded to
46          max. 100 audio channels) for most audio drivers
47        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
48          opposed to the LSCP specs
49        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
50          reflected the wrong value
51        - fixed a memory management bug in ASIO driver
52        - Makefile fix: JACK_CFLAGS wasn't used
53        - JACK: use jack_client_open instead of the deprecated
54          jack_client_new
55        - added (experimental) CoreAudio driver
56    
57      * MIDI driver:
58        - added JACK MIDI driver
59        - dispatch bank select as ordinary CC as well, the user might seriously
60          want to (mis)use it for some purpose ("fixed" in all current MIDI
61          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
62    
63      * instruments database:
64        - avoid time consuming samples scanning when adding instruments
65          to the instruments database
66        - added support for handling lost files in the instruments database
67        - Implemented option for adding instruments in separate directories
68          in the instruments database
69          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
70    
71      * Gigasampler format engine:
72        - fixed a memory leak that could happen when a channel was deleted
73          while notes were playing
74        - made it possible to load an instrument even if the audio thread
75          isn't running
76        - added partial support for the "Controller Triggered" MIDI rule,
77          enough for piano gigs with pedal noise samples
78        - minor fix: only mark FX sends as being modified if really the
79          respective FX send MIDI controller was used
80        - added support for GM global device volume SysEx message
81          (can be selected at compile time to either apply globally to the
82          whole sampler [default] or only to the sampler channels that are
83          connected to the respective MIDI input port the SysEx message arrived
84          on)
85        - bugfix: notes triggered at position 0 in the audio buffer were
86          sometimes wrongly killed in the same buffer, causing no sound to
87          be played
88        - added support for chromatic / drumkit mode Roland GS Sysex message
89          which is usally used to switch a part between chromatic sounds and
90          drumkit sounds (as opposed to their common default setting of MIDI
91          part 10 being a drumkit part and all other ones chromatic parts), in
92          LS however one can switch between the first 16 MIDI instrument maps
93          defined for the sampler
94        - made it possible to create multiple sample channels even if the
95          audio thread isn't running
96    
97      * LSCP server:
98        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
99          react on MIDI data arriving on certain sampler channels (so far only
100          Note-On and Note-Off events are sent via this LSCP event)
101        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
102          react on MIDI data arriving on certain MIDI input devices (so far only
103          Note-On and Note-Off events are sent via this LSCP event)
104        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
105          SET DB_INSTRUMENT FILE_PATH
106        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
107          frontends to send MIDI messages to specific sampler channel
108        - added two additional fields to GET FILE INSTRUMENT INFO command -
109          KEY_BINDINGS and KEYSWITCH_BINDINGS
110        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
111          was incorrect
112        - Optimized the retrieval of the MIDI instrument mappings
113        - added new LSCP command "SET VOICES" to globally alter the maximum
114          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
115          be triggered respectively
116        - added new LSCP command "SET STREAMS" to globally alter the maximum
117          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
118          which will be triggered respectively
119        - bugfix: retry if "select" returns EINTR (this fixes a crash when
120          a gigedit file dialog is opened)
121    
122      * Bug fixes:
123        - fixed a crash which occurs when removing a sampler channel waiting
124          to start instrument loading after another channel
125        - fixed a crash which occurs when removing a sampler channel with
126          instrument loading in progress (bug #113)
127        - fixed termination caused by uncaught exception when adding MIDI
128          instrument with PERSISTENT load mode
129    
130    
131    Version 0.5.1 (6 December 2007)
132    
133      * packaging changes:
134        - added autoconf checks for pthread library
135        - added autoconf check for pthread bug found on certain NPTL-enabled
136          glibc versions (see Gentoo bug report #194076)
137        - added autoconf checks for MS Windows
138    
139      * general changes:
140        - bugfix: the thread used by an editor plugin didn't die when the
141          editor closed
142        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
143          out all the space. operator--() did not apply size_mask after
144          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
145          order to avoid problems with the _NonVolatileReader functions.
146        - bugfix: Stream.h: added a missing divide by BytesPerSample in
147          GetWriteSpace(). Since this function is currently only used in
148          the stream's qsort() compare function, it didn't trigger any
149          bugs.
150        - Resampler.h, Synthesizer.h: cubic interpolation now works in
151          24bit mode too. Faster method to read 24bit words on little
152          endian machines (x86): replaced 3 byte reads + shifts with a 1
153          unaligned 32bit read and shift
154        - experimental support for MS Windows (MIDI input via MME, AUDIO
155          output via ASIO)
156        - made handling of SIGINT signal (Ctrl-C) a bit more robust
157        - support for monitoring the total number of active disk streams
158          (new LSCP commands: GET TOTAL_STREAM_COUNT,
159          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
160    
161      * AUDIO driver:
162        - added Windows ASIO low latency audio driver
163    
164      * MIDI driver:
165        - added MME Windows MIDI driver
166    
167      * LSCP server:
168        - added support for Windows style path / filenames, however with
169          forward slash path separators instead of backslash
170          (i.e. "C:/foo/bar.gig")
171        - allow naughty liblscp to send non-string device parameters within
172          apostrophes as well
173        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
174          "LIST FILE INSTRUMENTS <file>" and
175          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
176          about an arbitrary instrument file on the system where the sampler is
177          running on
178    
179    Version 0.5.0 (15 October 2007)
180    
181      * packaging changes:
182        - config.h is not going to be installed along with liblinuxsampler's
183          API header files anymore
184      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to

190        - fixed buggy boolean --enable-foo / --disable-foo configure script
191          parameters
192        - global.h now only covers global definitions that are needed for the
193          C++ API header files, all implementation internal global definitions
194          are now in global_private.h
195        - atomic.h is not exposed to the C++ API anymore
196        - no need to include config.h anymore for using LS's API header files
197        - fixed warnings in API doc generation

229      - implemented instruments database      - implemented instruments database
230        - added support for escape sequences to the instruments database
231        - added highly experimental support for on-the-fly instrument editing
232          within the sampler's process (by using instrument editor plugins),
233          you'll notice the new "Registered instrument editors:" message on
234          startup, added a new LSCP command:
235          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
236          to spawn a matching instrument editor for the instrument on the
237          given sampler channel, the plugin path can be overridden at compile
238          time with ./configure --enable-plugin-dir=/some/dir
239        - added experimental code for synchronizing instrument editors hosted
240          in the sampler's process to safely edit instruments while playing
241          without a crash (hopefully) by either suspending single regions
242          wherever possible or if unavoidable whole engine(s)
243        - fixed several issues in fundamental "Thread" class: set scheduling
244          policy and priority on thread level, set a minimum stack size for
245          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
246          threads simply inherited properties of starting thread instead of
247          setting their own policy and priority
248        - minor fix in our automatic stack trace mechanism on crashes, the
249          main process did not wait for the stack trace process to finish
250          its output
251        - fixed some minor memory leaks
252        - reenabled assembly features support, at the moment only for
253          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
254        - minor assembly fix in x86 features detection (don't use the PIC
255          register, to avoid relocations in the text segment at runtime)
256        - POSIX callback functions of Thread.h are hidden
257

282        - fixed compiler error when --enable-override-filter-type was
283          supplied to the configure script (fixes #46)
284        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
285          instead of a fix value
286        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
287          127 (solo mode) only kill voices if the respective mode really
288          changed
289    
290      * LSCP server:
291        - fixed compile time error for old Bison versions
292          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
293        - parser now supports extended ASCII character set
294          (up to ASCII code 255, i.e. includes now umlauts and accents)
295        - filename arguments in LSCP commands now allow to use escape
296          sequences, that is directly literal as one of: \', \", \\, \n, \r,
297          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
298          code value like \xf2) (fixes bug #24)
299        - the following LSCP commands now also support escape sequences for at
300          least one of their text-based parameters (i.e. name, description):
301          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
302          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
303          "SET DB_INSTRUMENT_DIRECTORY NAME",
304          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
305          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
306          "FIND DB_INSTRUMENT_DIRECTORIES"
307        - returns verbose syntax errors (line and column where syntax error
308          occured, the unexpected character and the actually expected, possible
309          character(s), the latter only if less than 5 possibilities)
310        - made sure that LSCP syntax is not affected by gigedit locale
311          settings
312        - bugfix regarding strings parameter lists: all comma separated lists
313          of strings were treated as being one string containing commas
314          (fixes #57)
315    
316    * Bug fixes:    * Bug fixes:
317      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
318      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
319        channel audio output device"        channel audio output device"
320        - fixed a crash which occurs when reassigning the same engine
321          on a sampler channel with connected MIDI device
322        - fixed a crash which occurs when changing the number of ports of a MIDI
323          device connected to a sampler channel to number less then or equal
324          to the index of the port to which the sampler channel is connected.
325        - The previous bindings were not been disconnected when altering
326          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
327          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
328        - The active stream/voice count statistic was incorrect.
329        - notification events were not been sent for some sampler
330          channel changes
331        - added default min and max values to restrict the number of allowed
332          audio output channels and MIDI input ports
333        - the connection to the PCM interface is now closed when destroying
334          an audio output device
335        - files with slash in their path or filename could not be loaded
336    
337      * test cases:
338        - updated and fixed (haven't been touched in a while)
