# Line 1  Line 1 
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    
9      * general changes:
10        - bugfix: on some POSIX systems instrument editor plugins refused to
11          load as we used a non-portable Linux specific struct field
12          (fixes bug #70, patch by Ronald Baljeu)
13        - fixed endless loop which occured when loading an instrument editor
14          plugin DLL on Windows systems failed
15        - fixed memory leaks that occurred when liblinuxsampler was unloaded
16        - optimized the SynchronizedConfig class so it doesn't wait
17          unnecessarily long after an update
18        - added support for notifying instrument editors on note-on / note-off
19          events (e.g. to highlight the pressed keys on the virtual keyboard
20          of gigedit)
21        - added support for triggering notes by instrument editors (see above)
22        - be verbose on DLL load errors (on Linux)
23        - fixed di-harmonic triangle LFO implementation (this LFO implementation
24          is only used by very few systems, most pick the int math
25          implementation, which is usually faster)
26    
27      * audio driver:
28        - removed the nonsense audio channel constraint (which was hard coded to
29          max. 100 audio channels) for most audio drivers
30        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
31          opposed to the LSCP specs
32        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
33          reflected the wrong value
34        - fixed a memory management bug in ASIO driver
35    
36      * MIDI driver:
37        - added JACK MIDI driver
38    
39      * instruments database:
40        - avoid time consuming samples scanning when adding instruments
41          to the instruments database
42    
43      * Gigasampler format engine:
44        - fixed a memory leak that could happen when a channel was deleted
45          while notes were playing
46        - made it possible to load an instrument even if the audio thread
47          isn't running
48    
49      * LSCP server:
50        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
51          react on MIDI data arriving on certain sampler channels (so far only
52          Note-On and Note-Off events are sent via this LSCP event)
53        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
54          react on MIDI data arriving on certain MIDI input devices (so far only
55          Note-On and Note-Off events are sent via this LSCP event)
56    
57    Version 0.5.1 (6 December 2007)
58    
59      * packaging changes:
60        - added autoconf checks for pthread library
61        - added autoconf check for pthread bug found on certain NPTL-enabled
62          glibc versions (see Gentoo bug report #194076)
63        - added autoconf checks for MS Windows
64    
65      * general changes:
66        - bugfix: the thread used by an editor plugin didn't die when the
67          editor closed
68        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
69          out all the space. operator--() did not apply size_mask after
70          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
71          order to avoid problems with the _NonVolatileReader functions.
72        - bugfix: Stream.h: added a missing divide by BytesPerSample in
73          GetWriteSpace(). Since this function is currently only used in
74          the stream's qsort() compare function, it didn't trigger any
75          bugs.
76        - Resampler.h, Synthesizer.h: cubic interpolation now works in
77          24bit mode too. Faster method to read 24bit words on little
78          endian machines (x86): replaced 3 byte reads + shifts with a 1
79          unaligned 32bit read and shift
80        - experimental support for MS Windows (MIDI input via MME, AUDIO
81          output via ASIO)
82        - made handling of SIGINT signal (Ctrl-C) a bit more robust
83        - support for monitoring the total number of active disk streams
84          (new LSCP commands: GET TOTAL_STREAM_COUNT,
85          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
86    
87      * AUDIO driver:
88        - added Windows ASIO low latency audio driver
89    
90      * MIDI driver:
91        - added MME Windows MIDI driver
92    
93      * LSCP server:
94        - added support for Windows style path / filenames, however with
95          forward slash path separators instead of backslash
96          (i.e. "C:/foo/bar.gig")
97        - allow naughty liblscp to send non-string device parameters within
98          apostrophes as well
99        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
100          "LIST FILE INSTRUMENTS <file>" and
101          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
102          about an arbitrary instrument file on the system where the sampler is
103          running on
104    
105    Version 0.5.0 (15 October 2007)
106    
107      * packaging changes:
108        - config.h is not going to be installed along with liblinuxsampler's
109          API header files anymore
110      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to

116        - fixed buggy boolean --enable-foo / --disable-foo configure script
117          parameters
118        - global.h now only covers global definitions that are needed for the
119          C++ API header files, all implementation internal global definitions
120          are now in global_private.h
121        - atomic.h is not exposed to the C++ API anymore
122        - no need to include config.h anymore for using LS's API header files
123        - fixed warnings in API doc generation

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

208        - fixed compiler error when --enable-override-filter-type was
209          supplied to the configure script (fixes #46)
210        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
211          instead of a fix value
212        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
213          127 (solo mode) only kill voices if the respective mode really
214          changed
215    
216      * LSCP server:
217        - fixed compile time error for old Bison versions
218          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
219        - parser now supports extended ASCII character set
220          (up to ASCII code 255, i.e. includes now umlauts and accents)
221        - filename arguments in LSCP commands now allow to use escape
222          sequences, that is directly literal as one of: \', \", \\, \n, \r,
223          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
224          code value like \xf2) (fixes bug #24)
225        - the following LSCP commands now also support escape sequences for at
226          least one of their text-based parameters (i.e. name, description):
227          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
228          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
229          "SET DB_INSTRUMENT_DIRECTORY NAME",
230          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
231          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
232          "FIND DB_INSTRUMENT_DIRECTORIES"
233        - returns verbose syntax errors (line and column where syntax error
234          occured, the unexpected character and the actually expected, possible
235          character(s), the latter only if less than 5 possibilities)
236        - made sure that LSCP syntax is not affected by gigedit locale
237          settings
238        - bugfix regarding strings parameter lists: all comma separated lists
239          of strings were treated as being one string containing commas
240          (fixes #57)
241    
242    * Bug fixes:    * Bug fixes:
243      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
244      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
245        channel audio output device"        channel audio output device"
246        - fixed a crash which occurs when reassigning the same engine
247          on a sampler channel with connected MIDI device
248        - fixed a crash which occurs when changing the number of ports of a MIDI
249          device connected to a sampler channel to number less then or equal
250          to the index of the port to which the sampler channel is connected.
251        - The previous bindings were not been disconnected when altering
252          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
253          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
254        - The active stream/voice count statistic was incorrect.
255        - notification events were not been sent for some sampler
256          channel changes
257        - added default min and max values to restrict the number of allowed
258          audio output channels and MIDI input ports
259        - the connection to the PCM interface is now closed when destroying
260          an audio output device
261        - files with slash in their path or filename could not be loaded
262
