# Line 1  Line 1 
1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3      * general changes:
4        - bugfix: on some POSIX systems instrument editor plugins refused to
5          load as we used a non-portable Linux specific struct field
6          (fixes bug #70, patch by Ronald Baljeu)
7        - fixed endless loop which occured when loading an instrument editor
8          plugin DLL on Windows systems failed
9    
10      * audio driver:
11        - removed the nonsense audio channel constraint (which was hard coded to
12          max. 100 audio channels) for most audio drivers
13        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
14          opposed to the LSCP specs
15    
16      * instruments database:
17        - avoid time consuming samples scanning when adding instruments
18          to the instruments database
19    
20    Version 0.5.1 (6 December 2007)
21    
22      * packaging changes:
23        - added autoconf checks for pthread library
24        - added autoconf check for pthread bug found on certain NPTL-enabled
25          glibc versions (see Gentoo bug report #194076)
26        - added autoconf checks for MS Windows
27    
28      * general changes:
29        - bugfix: the thread used by an editor plugin didn't die when the
30          editor closed
31        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
32          out all the space. operator--() did not apply size_mask after
33          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
34          order to avoid problems with the _NonVolatileReader functions.
35        - bugfix: Stream.h: added a missing divide by BytesPerSample in
36          GetWriteSpace(). Since this function is currently only used in
37          the stream's qsort() compare function, it didn't trigger any
38          bugs.
39        - Resampler.h, Synthesizer.h: cubic interpolation now works in
40          24bit mode too. Faster method to read 24bit words on little
41          endian machines (x86): replaced 3 byte reads + shifts with a 1
42          unaligned 32bit read and shift
43        - experimental support for MS Windows (MIDI input via MME, AUDIO
44          output via ASIO)
45        - made handling of SIGINT signal (Ctrl-C) a bit more robust
46        - support for monitoring the total number of active disk streams
47          (new LSCP commands: GET TOTAL_STREAM_COUNT,
48          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
49    
50      * AUDIO driver:
51        - added Windows ASIO low latency audio driver
52    
53      * MIDI driver:
54        - added MME Windows MIDI driver
55    
56      * LSCP server:
57        - added support for Windows style path / filenames, however with
58          forward slash path separators instead of backslash
59          (i.e. "C:/foo/bar.gig")
60        - allow naughty liblscp to send non-string device parameters within
61          apostrophes as well
62        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
63          "LIST FILE INSTRUMENTS <file>" and
64          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
65          about an arbitrary instrument file on the system where the sampler is
66          running on
67    
68    Version 0.5.0 (15 October 2007)
69    
70      * packaging changes:
71        - config.h is not going to be installed along with liblinuxsampler's
72          API header files anymore
73        - only the API relevant header (and source) files will be exported to
74          the Doxygen API documentation (explicitly listed in Doxyfile.in)
75        - added completely new XCode project files for Mac OSX which is now
76          capable to execute our autoconf environment, thus no need anymore
77          to maintain the compile time configuration file (osx/version.h) for
78          OSX manually (patch by Toshi Nagata)
79        - fixed buggy boolean --enable-foo / --disable-foo configure script
80          parameters
81        - global.h now only covers global definitions that are needed for the
82          C++ API header files, all implementation internal global definitions
83          are now in global_private.h
84        - atomic.h is not exposed to the C++ API anymore
85        - no need to include config.h anymore for using LS's API header files
86        - fixed warnings in API doc generation
87    
88      * general changes:
89        - replaced the old, confusing MIDI program change mechanism by a
90          flexible MIDI instrument mapper which allows to map arbitrary
91          (MIDI bank, MIDI program) pairs with arbitrary
92          (engine type, instrument file, file index) triplets which will be
93          loaded on the respective channel when such MIDI program change
94          messages arrive, beside that, each entry allows to define a life-time
95          strategy for the instrument, so the user can define whether the
96          instrument should i.e. be permanently loaded (to be able to switch
97          quickly among sounds) or i.e. loaded just on demand when the
98          respective program change arrives (to safe RAM space), as well as a
99          global volume factor for each entry, so the user can adjust the volume
100          dynamic of his mapped instrument collection without having to modify
101          the instrument files, also one can manage arbitrary amount of such
102          MIDI instrument maps and assign each sampler channel individually
103          a certain map, so that i.e. separation of normal instruments and
104          drumkits is possible
105        - new notification events for tracking changes to audio/MIDI devices,
106          MIDI instrument maps, MIDI instruments, FX sends, global volume.
107        - sampler was limited to load max. 200 instruments in the background
108          due to a constant size RingBuffer FIFO which is now replaced by a
109          dynamic (unlimited) size std::list FIFO
110        - added FX sends, these allow to route audio signals to arbitrary audio
111          output channels for being processed by external effect processors
112          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
113          controllers
114        - global (sampler wide) volume can now be controlled at runtime
115        - Implemented new, improved notification system
116        - fixed compilation errors regarding OSX
117          (patch by Toshi Nagata)
118        - implemented instruments database
119        - added support for escape sequences to the instruments database
120        - added highly experimental support for on-the-fly instrument editing
121          within the sampler's process (by using instrument editor plugins),
122          you'll notice the new "Registered instrument editors:" message on
123          startup, added a new LSCP command:
124          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
125          to spawn a matching instrument editor for the instrument on the
126          given sampler channel, the plugin path can be overridden at compile
127          time with ./configure --enable-plugin-dir=/some/dir
128        - added experimental code for synchronizing instrument editors hosted
129          in the sampler's process to safely edit instruments while playing
130          without a crash (hopefully) by either suspending single regions
131          wherever possible or if unavoidable whole engine(s)
132        - fixed several issues in fundamental "Thread" class: set scheduling
133          policy and priority on thread level, set a minimum stack size for
134          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
135          threads simply inherited properties of starting thread instead of
136          setting their own policy and priority
137        - minor fix in our automatic stack trace mechanism on crashes, the
138          main process did not wait for the stack trace process to finish
139          its output
140        - fixed some minor memory leaks
141        - reenabled assembly features support, at the moment only for
142          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
143        - minor assembly fix in x86 features detection (don't use the PIC
144          register, to avoid relocations in the text segment at runtime)
145        - POSIX callback functions of Thread.h are hidden
146    
147      * MIDI driver:
148        - dispatch bank select (MSB and LSB) messages
149    
150      * audio driver:
151        - the ALSA audio output driver parameters now reflect the correct
152          parameter value ranges for the respective selected sound card
153          (patch by Till Wimmer, a bit fixed and extended)
154    
155      * Gigasampler format engine:
156        - if a filter is used and EG2 finishes before EG1, let the voice
157          die when EG2 has finished (this fixes a problem with clicks and
158          voice starvation for some gigs)
159        - playback is no longer disabled during instrument loading
160        - all notes playing on a channel that changes its instrument keep
161          playing with the old instrument until they get a note off
162          command
163        - EG fix: a release value of zero could cause noises or crash
164        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
165        - EG fine tuning: when attack is zero the EG starts at a level
166          above max sustain level, which means that there is a decay phase
167          even if sustain is 100%
168        - more EG fixes: the level could sometimes go below zero and cause
169          noises or crashes
170        - minor fix of EGDecay (patch by Toshi Nagata)
171        - fixed compiler error when --enable-override-filter-type was
172          supplied to the configure script (fixes #46)
173        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
174          instead of a fix value
175        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
176          127 (solo mode) only kill voices if the respective mode really
177          changed
178    
179      * LSCP server:
180        - fixed compile time error for old Bison versions
181          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
182        - parser now supports extended ASCII character set
183          (up to ASCII code 255, i.e. includes now umlauts and accents)
184        - filename arguments in LSCP commands now allow to use escape
185          sequences, that is directly literal as one of: \', \", \\, \n, \r,
186          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
187          code value like \xf2) (fixes bug #24)
188        - the following LSCP commands now also support escape sequences for at
189          least one of their text-based parameters (i.e. name, description):
190          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
191          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
192          "SET DB_INSTRUMENT_DIRECTORY NAME",
193          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
194          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
195          "FIND DB_INSTRUMENT_DIRECTORIES"
196        - returns verbose syntax errors (line and column where syntax error
197          occured, the unexpected character and the actually expected, possible
198          character(s), the latter only if less than 5 possibilities)
199        - made sure that LSCP syntax is not affected by gigedit locale
200          settings
201        - bugfix regarding strings parameter lists: all comma separated lists
202          of strings were treated as being one string containing commas
203          (fixes #57)
204    
205      * Bug fixes:
206        - fixed crash occurring on certain LSCP scripts (Bug 39)
207        - another thread safety fix for lscp "load engine" and "set
208          channel audio output device"
209        - fixed a crash which occurs when reassigning the same engine
210          on a sampler channel with connected MIDI device
211        - fixed a crash which occurs when changing the number of ports of a MIDI
212          device connected to a sampler channel to number less then or equal
213          to the index of the port to which the sampler channel is connected.
214        - The previous bindings were not been disconnected when altering
215          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
216          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
217        - The active stream/voice count statistic was incorrect.
218        - notification events were not been sent for some sampler
219          channel changes
220        - added default min and max values to restrict the number of allowed
221          audio output channels and MIDI input ports
222        - the connection to the PCM interface is now closed when destroying
223          an audio output device
224        - files with slash in their path or filename could not be loaded
225    
226      * test cases:
227        - updated and fixed (haven't been touched in a while)
