2    
3      * packaging changes:
4        - added autoconf checks for pthread library
5        - added autoconf check for pthread bug found on certain NPTL-enabled
6          glibc versions (see Gentoo bug report #194076)
7    
8    Version 0.5.0 (15 October 2007)
9    
10      * packaging changes:
11        - config.h is not going to be installed along with liblinuxsampler's
12          API header files anymore
13        - only the API relevant header (and source) files will be exported to
14          the Doxygen API documentation (explicitly listed in Doxyfile.in)
15        - added completely new XCode project files for Mac OSX which is now
16          capable to execute our autoconf environment, thus no need anymore
17          to maintain the compile time configuration file (osx/version.h) for
18          OSX manually (patch by Toshi Nagata)
19        - fixed buggy boolean --enable-foo / --disable-foo configure script
20          parameters
21        - global.h now only covers global definitions that are needed for the
22          C++ API header files, all implementation internal global definitions
23          are now in global_private.h
24        - atomic.h is not exposed to the C++ API anymore
25        - no need to include config.h anymore for using LS's API header files
26        - fixed warnings in API doc generation
27    
28    * general changes:    * general changes:

45      - new notification events for tracking audio/MIDI device changes,      - new notification events for tracking changes to audio/MIDI devices,
46        MIDI instrument map changes and MIDI instrument changes        MIDI instrument maps, MIDI instruments, FX sends, global volume.
47      - sampler was limited to load max. 200 instruments in the background      - sampler was limited to load max. 200 instruments in the background

49        dynamic (unlimited) size std::list FIFO        dynamic (unlimited) size std::list FIFO
50        - added FX sends, these allow to route audio signals to arbitrary audio
51          output channels for being processed by external effect processors
52          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
53          controllers
54        - global (sampler wide) volume can now be controlled at runtime
55        - Implemented new, improved notification system
56        - fixed compilation errors regarding OSX
57          (patch by Toshi Nagata)
58        - implemented instruments database
59        - added support for escape sequences to the instruments database
60        - added highly experimental support for on-the-fly instrument editing
61          within the sampler's process (by using instrument editor plugins),
62          you'll notice the new "Registered instrument editors:" message on
63          startup, added a new LSCP command:
64          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
65          to spawn a matching instrument editor for the instrument on the
66          given sampler channel, the plugin path can be overridden at compile
67          time with ./configure --enable-plugin-dir=/some/dir
68        - added experimental code for synchronizing instrument editors hosted
69          in the sampler's process to safely edit instruments while playing
70          without a crash (hopefully) by either suspending single regions
71          wherever possible or if unavoidable whole engine(s)
72        - fixed several issues in fundamental "Thread" class: set scheduling
73          policy and priority on thread level, set a minimum stack size for
74          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
75          threads simply inherited properties of starting thread instead of
76          setting their own policy and priority
77        - minor fix in our automatic stack trace mechanism on crashes, the
78          main process did not wait for the stack trace process to finish
79          its output
80        - fixed some minor memory leaks
81        - reenabled assembly features support, at the moment only for
82          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
83        - minor assembly fix in x86 features detection (don't use the PIC
84          register, to avoid relocations in the text segment at runtime)
85        - POSIX callback functions of Thread.h are hidden
86    
87    * MIDI driver:    * MIDI driver:
88      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
89    
90      * audio driver:
91        - the ALSA audio output driver parameters now reflect the correct
92          parameter value ranges for the respective selected sound card
93          (patch by Till Wimmer, a bit fixed and extended)
94    
95    * Gigasampler format engine:    * Gigasampler format engine:
96      - if a filter is used and EG2 finishes before EG1, let the voice      - if a filter is used and EG2 finishes before EG1, let the voice
97        die when EG2 has finished (this fixes a problem with clicks and        die when EG2 has finished (this fixes a problem with clicks and
98        voice starvation for some gigs)        voice starvation for some gigs)
99        - playback is no longer disabled during instrument loading
100        - all notes playing on a channel that changes its instrument keep
101          playing with the old instrument until they get a note off
102          command
103        - EG fix: a release value of zero could cause noises or crash
104        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
105        - EG fine tuning: when attack is zero the EG starts at a level
106          above max sustain level, which means that there is a decay phase
107          even if sustain is 100%
108        - more EG fixes: the level could sometimes go below zero and cause
109          noises or crashes
110        - minor fix of EGDecay (patch by Toshi Nagata)
111        - fixed compiler error when --enable-override-filter-type was
112          supplied to the configure script (fixes #46)
113        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
114          instead of a fix value
115        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
116          127 (solo mode) only kill voices if the respective mode really
117          changed
118    
119      * LSCP server:
120        - fixed compile time error for old Bison versions
121          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
122        - parser now supports extended ASCII character set
123          (up to ASCII code 255, i.e. includes now umlauts and accents)
124        - filename arguments in LSCP commands now allow to use escape
125          sequences, that is directly literal as one of: \', \", \\, \n, \r,
126          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
127          code value like \xf2) (fixes bug #24)
128        - the following LSCP commands now also support escape sequences for at
129          least one of their text-based parameters (i.e. name, description):
130          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
131          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
132          "SET DB_INSTRUMENT_DIRECTORY NAME",
133          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
134          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
135          "FIND DB_INSTRUMENT_DIRECTORIES"
136        - returns verbose syntax errors (line and column where syntax error
137          occured, the unexpected character and the actually expected, possible
138          character(s), the latter only if less than 5 possibilities)
139        - made sure that LSCP syntax is not affected by gigedit locale
140          settings
141        - bugfix regarding strings parameter lists: all comma separated lists
142          of strings were treated as being one string containing commas
143          (fixes #57)
144    
145    * Bug fixes:    * Bug fixes:
146      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
147        - another thread safety fix for lscp "load engine" and "set
148          channel audio output device"
149        - fixed a crash which occurs when reassigning the same engine
150          on a sampler channel with connected MIDI device
151        - fixed a crash which occurs when changing the number of ports of a MIDI
152          device connected to a sampler channel to number less then or equal
153          to the index of the port to which the sampler channel is connected.
154        - The previous bindings were not been disconnected when altering
155          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
156          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
157        - The active stream/voice count statistic was incorrect.
158        - notification events were not been sent for some sampler
159          channel changes
160        - added default min and max values to restrict the number of allowed
161          audio output channels and MIDI input ports
162        - the connection to the PCM interface is now closed when destroying
163          an audio output device
164        - files with slash in their path or filename could not be loaded
165    
166      * test cases:
167        - updated and fixed (haven't been touched in a while)
