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          (can be selected at compile time to either apply globally to the
63          whole sampler [default] or only to the sampler channels that are
64          connected to the respective MIDI input port the SysEx message arrived
65          on)
66        - bugfix: notes triggered at position 0 in the audio buffer were
67          sometimes wrongly killed in the same buffer, causing no sound to
68          be played
69        - added support for chromatic / drumkit mode Roland GS Sysex message
70          which is usally used to switch a part between chromatic sounds and
71          drumkit sounds (as opposed to their common default setting of MIDI
72          part 10 being a drumkit part and all other ones chromatic parts), in
73          LS however one can switch between the first 16 MIDI instrument maps
74          defined for the sampler
75    
76      * LSCP server:
77        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
78          react on MIDI data arriving on certain sampler channels (so far only
79          Note-On and Note-Off events are sent via this LSCP event)
80        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
81          react on MIDI data arriving on certain MIDI input devices (so far only
82          Note-On and Note-Off events are sent via this LSCP event)
83        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
84          SET DB_INSTRUMENT FILE_PATH
85        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
86          was incorrect
87    
88      * Bug fixes:
89        - fixed a crash which occurs when removing a sampler channel waiting
90          to start instrument loading after another channel
91    
92    
93    Version 0.5.1 (6 December 2007)
94    
95      * packaging changes:
96        - added autoconf checks for pthread library
97        - added autoconf check for pthread bug found on certain NPTL-enabled
98          glibc versions (see Gentoo bug report #194076)
99        - added autoconf checks for MS Windows
100    
101      * general changes:
102        - bugfix: the thread used by an editor plugin didn't die when the
103          editor closed
104        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
105          out all the space. operator--() did not apply size_mask after
106          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
107          order to avoid problems with the _NonVolatileReader functions.
108        - bugfix: Stream.h: added a missing divide by BytesPerSample in
109          GetWriteSpace(). Since this function is currently only used in
110          the stream's qsort() compare function, it didn't trigger any
111          bugs.
112        - Resampler.h, Synthesizer.h: cubic interpolation now works in
113          24bit mode too. Faster method to read 24bit words on little
114          endian machines (x86): replaced 3 byte reads + shifts with a 1
115          unaligned 32bit read and shift
116        - experimental support for MS Windows (MIDI input via MME, AUDIO
117          output via ASIO)
118        - made handling of SIGINT signal (Ctrl-C) a bit more robust
119        - support for monitoring the total number of active disk streams
120          (new LSCP commands: GET TOTAL_STREAM_COUNT,
121          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
122    
123      * AUDIO driver:
124        - added Windows ASIO low latency audio driver
125    
126      * MIDI driver:
127        - added MME Windows MIDI driver
128    
129      * LSCP server:
130        - added support for Windows style path / filenames, however with
131          forward slash path separators instead of backslash
132          (i.e. "C:/foo/bar.gig")
133        - allow naughty liblscp to send non-string device parameters within
134          apostrophes as well
135        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
136          "LIST FILE INSTRUMENTS <file>" and
137          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
138          about an arbitrary instrument file on the system where the sampler is
139          running on
140    
141    Version 0.5.0 (15 October 2007)
142    
143      * packaging changes:
144        - config.h is not going to be installed along with liblinuxsampler's
145          API header files anymore
146        - only the API relevant header (and source) files will be exported to
147          the Doxygen API documentation (explicitly listed in Doxyfile.in)
148        - added completely new XCode project files for Mac OSX which is now
149          capable to execute our autoconf environment, thus no need anymore
150          to maintain the compile time configuration file (osx/version.h) for
151          OSX manually (patch by Toshi Nagata)
152        - fixed buggy boolean --enable-foo / --disable-foo configure script
153          parameters
154        - global.h now only covers global definitions that are needed for the
155          C++ API header files, all implementation internal global definitions
156          are now in global_private.h
157        - atomic.h is not exposed to the C++ API anymore
158        - no need to include config.h anymore for using LS's API header files
159        - fixed warnings in API doc generation
160

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

241        - more EG fixes: the level could sometimes go below zero and cause
242          noises or crashes
243        - minor fix of EGDecay (patch by Toshi Nagata)
244        - fixed compiler error when --enable-override-filter-type was
245          supplied to the configure script (fixes #46)
246        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
247          instead of a fix value
248        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
249          127 (solo mode) only kill voices if the respective mode really
250          changed
251    
252      * LSCP server:
253        - fixed compile time error for old Bison versions
254          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
255        - parser now supports extended ASCII character set
256          (up to ASCII code 255, i.e. includes now umlauts and accents)
257        - filename arguments in LSCP commands now allow to use escape
258          sequences, that is directly literal as one of: \', \", \\, \n, \r,
259          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
260          code value like \xf2) (fixes bug #24)
261        - the following LSCP commands now also support escape sequences for at
262          least one of their text-based parameters (i.e. name, description):
263          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
264          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
265          "SET DB_INSTRUMENT_DIRECTORY NAME",
266          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
267          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
268          "FIND DB_INSTRUMENT_DIRECTORIES"
269        - returns verbose syntax errors (line and column where syntax error
270          occured, the unexpected character and the actually expected, possible
271          character(s), the latter only if less than 5 possibilities)
272        - made sure that LSCP syntax is not affected by gigedit locale
273          settings
274        - bugfix regarding strings parameter lists: all comma separated lists
275          of strings were treated as being one string containing commas
276          (fixes #57)
277    
278    * Bug fixes:    * Bug fixes:
279      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
280      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
281        channel audio output device"        channel audio output device"
282        - fixed a crash which occurs when reassigning the same engine
283          on a sampler channel with connected MIDI device
284        - fixed a crash which occurs when changing the number of ports of a MIDI
285          device connected to a sampler channel to number less then or equal
286          to the index of the port to which the sampler channel is connected.
287        - The previous bindings were not been disconnected when altering
288          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
289          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
290        - The active stream/voice count statistic was incorrect.
291        - notification events were not been sent for some sampler
292          channel changes
293        - added default min and max values to restrict the number of allowed
294          audio output channels and MIDI input ports
295        - the connection to the PCM interface is now closed when destroying
296          an audio output device
297        - files with slash in their path or filename could not be loaded
298
