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    
28      * audio driver:
29        - removed the nonsense audio channel constraint (which was hard coded to
30          max. 100 audio channels) for most audio drivers
31        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
32          opposed to the LSCP specs
33        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
34          reflected the wrong value
35        - fixed a memory management bug in ASIO driver
36    
37      * MIDI driver:
38        - added JACK MIDI driver
39        - dispatch bank select as ordinary CC as well, the user might seriously
40          want to (mis)use it for some purpose ("fixed" in all current MIDI
41          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
42    
43      * instruments database:
44        - avoid time consuming samples scanning when adding instruments
45          to the instruments database
46    
47      * Gigasampler format engine:
48        - fixed a memory leak that could happen when a channel was deleted
49          while notes were playing
50        - made it possible to load an instrument even if the audio thread
51          isn't running
52        - added partial support for the "Controller Triggered" MIDI rule,
53          enough for piano gigs with pedal noise samples
54        - minor fix: only mark FX sends as being modified if really the
55          respective FX send MIDI controller was used
56    
57      * LSCP server:
58        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
59          react on MIDI data arriving on certain sampler channels (so far only
60          Note-On and Note-Off events are sent via this LSCP event)
61        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
62          react on MIDI data arriving on certain MIDI input devices (so far only
63          Note-On and Note-Off events are sent via this LSCP event)
64    
65    Version 0.5.1 (6 December 2007)
66    
67      * packaging changes:
68        - added autoconf checks for pthread library
69        - added autoconf check for pthread bug found on certain NPTL-enabled
70          glibc versions (see Gentoo bug report #194076)
71        - added autoconf checks for MS Windows
72    
73      * general changes:
74        - bugfix: the thread used by an editor plugin didn't die when the
75          editor closed
76        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
77          out all the space. operator--() did not apply size_mask after
78          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
79          order to avoid problems with the _NonVolatileReader functions.
80        - bugfix: Stream.h: added a missing divide by BytesPerSample in
81          GetWriteSpace(). Since this function is currently only used in
82          the stream's qsort() compare function, it didn't trigger any
83          bugs.
84        - Resampler.h, Synthesizer.h: cubic interpolation now works in
85          24bit mode too. Faster method to read 24bit words on little
86          endian machines (x86): replaced 3 byte reads + shifts with a 1
87          unaligned 32bit read and shift
88        - experimental support for MS Windows (MIDI input via MME, AUDIO
89          output via ASIO)
90        - made handling of SIGINT signal (Ctrl-C) a bit more robust
91        - support for monitoring the total number of active disk streams
92          (new LSCP commands: GET TOTAL_STREAM_COUNT,
93          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
94    
95      * AUDIO driver:
96        - added Windows ASIO low latency audio driver
97    
98      * MIDI driver:
99        - added MME Windows MIDI driver
100    
101      * LSCP server:
102        - added support for Windows style path / filenames, however with
103          forward slash path separators instead of backslash
104          (i.e. "C:/foo/bar.gig")
105        - allow naughty liblscp to send non-string device parameters within
106          apostrophes as well
107        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
108          "LIST FILE INSTRUMENTS <file>" and
109          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
110          about an arbitrary instrument file on the system where the sampler is
111          running on
112    
113    Version 0.5.0 (15 October 2007)
114    
115      * packaging changes:
116        - config.h is not going to be installed along with liblinuxsampler's
117          API header files anymore
118      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to

124        - fixed buggy boolean --enable-foo / --disable-foo configure script
125          parameters
126        - global.h now only covers global definitions that are needed for the
127          C++ API header files, all implementation internal global definitions
128          are now in global_private.h
129        - atomic.h is not exposed to the C++ API anymore
130        - no need to include config.h anymore for using LS's API header files
131        - fixed warnings in API doc generation

163      - implemented instruments database      - implemented instruments database
164        - added support for escape sequences to the instruments database
165        - added highly experimental support for on-the-fly instrument editing
166          within the sampler's process (by using instrument editor plugins),
167          you'll notice the new "Registered instrument editors:" message on
168          startup, added a new LSCP command:
169          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
170          to spawn a matching instrument editor for the instrument on the
171          given sampler channel, the plugin path can be overridden at compile
172          time with ./configure --enable-plugin-dir=/some/dir
173        - added experimental code for synchronizing instrument editors hosted
174          in the sampler's process to safely edit instruments while playing
175          without a crash (hopefully) by either suspending single regions
176          wherever possible or if unavoidable whole engine(s)
177        - fixed several issues in fundamental "Thread" class: set scheduling
178          policy and priority on thread level, set a minimum stack size for
179          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
180          threads simply inherited properties of starting thread instead of
181          setting their own policy and priority
182        - minor fix in our automatic stack trace mechanism on crashes, the
183          main process did not wait for the stack trace process to finish
184          its output
185        - fixed some minor memory leaks
186        - reenabled assembly features support, at the moment only for
187          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
188        - minor assembly fix in x86 features detection (don't use the PIC
189          register, to avoid relocations in the text segment at runtime)
190        - POSIX callback functions of Thread.h are hidden
191

216        - fixed compiler error when --enable-override-filter-type was
217          supplied to the configure script (fixes #46)
218        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
219          instead of a fix value
220        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
221          127 (solo mode) only kill voices if the respective mode really
222          changed
223    
224      * LSCP server:
225        - fixed compile time error for old Bison versions
226          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
227        - parser now supports extended ASCII character set
228          (up to ASCII code 255, i.e. includes now umlauts and accents)
229        - filename arguments in LSCP commands now allow to use escape
230          sequences, that is directly literal as one of: \', \", \\, \n, \r,
231          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
232          code value like \xf2) (fixes bug #24)
233        - the following LSCP commands now also support escape sequences for at
234          least one of their text-based parameters (i.e. name, description):
235          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
236          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
237          "SET DB_INSTRUMENT_DIRECTORY NAME",
238          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
239          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
240          "FIND DB_INSTRUMENT_DIRECTORIES"
241        - returns verbose syntax errors (line and column where syntax error
242          occured, the unexpected character and the actually expected, possible
243          character(s), the latter only if less than 5 possibilities)
244        - made sure that LSCP syntax is not affected by gigedit locale
245          settings
246        - bugfix regarding strings parameter lists: all comma separated lists
247          of strings were treated as being one string containing commas
248          (fixes #57)
249    
250    * Bug fixes:    * Bug fixes:
251      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
252      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
253        channel audio output device"        channel audio output device"
254        - fixed a crash which occurs when reassigning the same engine
255          on a sampler channel with connected MIDI device
256        - fixed a crash which occurs when changing the number of ports of a MIDI
257          device connected to a sampler channel to number less then or equal
258          to the index of the port to which the sampler channel is connected.
259        - The previous bindings were not been disconnected when altering
260          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
261          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
262        - The active stream/voice count statistic was incorrect.
263        - notification events were not been sent for some sampler
264          channel changes
265        - added default min and max values to restrict the number of allowed
266          audio output channels and MIDI input ports
267        - the connection to the PCM interface is now closed when destroying
268          an audio output device
269        - files with slash in their path or filename could not be loaded
270
