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        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10        - fixed configure so it detects x86_64 (#107)
11        - fixes for building with newer MinGW versions
12        - fix for building with bison 2.4 (#111)
13        - fixed building with libgig installed in a non-standard directory
14    
15      * general changes:
16        - bugfix: on some POSIX systems instrument editor plugins refused to
17          load as we used a non-portable Linux specific struct field
18          (fixes bug #70, patch by Ronald Baljeu)
19        - fixed endless loop which occured when loading an instrument editor
20          plugin DLL on Windows systems failed
21        - fixed memory leaks that occurred when liblinuxsampler was unloaded
22        - optimized the SynchronizedConfig class so it doesn't wait
23          unnecessarily long after an update
24        - added support for notifying instrument editors on note-on / note-off
25          events (e.g. to highlight the pressed keys on the virtual keyboard
26          of gigedit)
27        - added support for triggering notes by instrument editors (see above)
28        - be verbose on DLL load errors (on Linux)
29        - fixed di-harmonic triangle LFO implementation (this LFO implementation
30          is only used by very few systems, most pick the int math
31          implementation, which is usually faster)
32        - fixes for audio drivers with varying buffer sizes
33        - experimental support for running LinuxSampler as a DSSI, LV2 and
34          VST plugin
35        - notification events for stream/voice count statistics are now sent
36          only when there are actual changes
37        - added memory ordering constraints to improve stability on
38          multi-core and multi-cpu systems
39        - maximum voices and disk streams can now be altered at runtime
40        - fixed CPU feature detection on x86_64 (maybe fixes #108)
41        - automatic stacktrace mechanism is now turned off by default and can
42          be switched on by command line option "--stacktrace" (the automatic
43          stacktrace mechanism seems to be broken on most systems at the moment)
44        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
45          a pointer to the launched InstrumentEditor object
46        - added optional 3rd party user data parameter for following
47          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
48          InstrumentEditor::Launch(),
49          InstrumentManager::LaunchInstrumentEditor()
50        - theoretical fix: made SynchronizedConfig follow C++0x memory
51          model more strictly
52    
53      * audio driver:
54        - removed the nonsense audio channel constraint (which was hard coded to
55          max. 100 audio channels) for most audio drivers
56        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
57          opposed to the LSCP specs
58        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
59          reflected the wrong value
60        - fixed a memory management bug in ASIO driver
61        - Makefile fix: JACK_CFLAGS wasn't used
62        - JACK: use jack_client_open instead of the deprecated
63          jack_client_new
64        - added (experimental) CoreAudio driver
65    
66      * MIDI driver:
67        - added JACK MIDI driver
68        - dispatch bank select as ordinary CC as well, the user might seriously
69          want to (mis)use it for some purpose ("fixed" in all current MIDI
70          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
71        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, Mme,
72          CoreMidi or AU
73    
74      * instruments database:
75        - avoid time consuming samples scanning when adding instruments
76          to the instruments database
77        - added support for handling lost files in the instruments database
78        - Implemented option for adding instruments in separate directories
79          in the instruments database
80          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
81    
82      * Gigasampler format engine:
83        - fixed a memory leak that could happen when a channel was deleted
84          while notes were playing
85        - made it possible to load an instrument even if the audio thread
86          isn't running
87        - added partial support for the "Controller Triggered" MIDI rule,
88          enough for piano gigs with pedal noise samples
89        - minor fix: only mark FX sends as being modified if really the
90          respective FX send MIDI controller was used
91        - added support for GM global device volume SysEx message
92          (can be selected at compile time to either apply globally to the
93          whole sampler [default] or only to the sampler channels that are
94          connected to the respective MIDI input port the SysEx message arrived
95          on)
96        - bugfix: notes triggered at position 0 in the audio buffer were
97          sometimes wrongly killed in the same buffer, causing no sound to
98          be played
99        - added support for chromatic / drumkit mode Roland GS Sysex message
100          which is usally used to switch a part between chromatic sounds and
101          drumkit sounds (as opposed to their common default setting of MIDI
102          part 10 being a drumkit part and all other ones chromatic parts), in
103          LS however one can switch between the first 16 MIDI instrument maps
104          defined for the sampler
105        - made it possible to create multiple sample channels even if the
106          audio thread isn't running
107        - fixed crash when removing channel with active voices (#116)
108        - bugfix: on sample reference changes (instrument editor), only
109          un-cache the respective sample if it's really not used by any
110          sampler engine anymore
111        - re-cache samples in case they were changed by an instrument editor,
112          e.g. when a sample was added while playing (#82)
113        - fixed hanging notes which occured when note-off event had the exact
114          same time stamp as the voice's note-on event and occured both in the
115          same audio fragment cycle (fixes bug #112)
116        - added support for the "fine tune" and "pitch bend range"
117          instrument-level gig parameters
118        - fixed minor artifacts in pitch bend handling
119        - added support for GS Reset SysEx message
120        - allow gig files to use unlimited downward pitch shifting
121        - added a limit check for upward pitch shifting
122    
123      * LSCP server:
124        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
125          react on MIDI data arriving on certain sampler channels (so far only
126          Note-On and Note-Off events are sent via this LSCP event)
127        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
128          react on MIDI data arriving on certain MIDI input devices (so far only
129          Note-On and Note-Off events are sent via this LSCP event)
130        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
131          SET DB_INSTRUMENT FILE_PATH
132        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
133          frontends to send MIDI messages to specific sampler channel
134        - added two additional fields to GET FILE INSTRUMENT INFO command -
135          KEY_BINDINGS and KEYSWITCH_BINDINGS
136        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
137          was incorrect
138        - Optimized the retrieval of the MIDI instrument mappings
139        - added new LSCP command "SET VOICES" to globally alter the maximum
140          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
141          be triggered respectively
142        - added new LSCP command "SET STREAMS" to globally alter the maximum
143          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
144          which will be triggered respectively
145        - bugfix: retry if "select" returns EINTR (this fixes a crash when
146          a gigedit file dialog is opened)
147        - close all connections when LSCPServer is deleted
148        - hard close of all sockets on exit
149    
150      * Bug fixes:
151        - fixed a crash which occurs when removing a sampler channel waiting
152          to start instrument loading after another channel
153        - fixed a crash which occurs when removing a sampler channel with
154          instrument loading in progress (bug #113)
155        - fixed termination caused by uncaught exception when adding MIDI
156          instrument with PERSISTENT load mode
157        - fixed possible iterator invalidations when resetting the sampler
158        - fixed memory leaks when issuing the following LSCP commands:
159          GET AUDIO_OUTPUT_DRIVER INFO
160          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
161          GET MIDI_INPUT_DRIVER INFO
162          GET MIDI_INPUT_DRIVER_PARAMETER INFO
163        - fixed possible compilation error when sqlite is not present
164        - fixed orphaned pointers when setting maximum voices limit (bug #118)
165        - fixed crash when changing the audio output device of a sampler
166          channel with loaded instrument and start playing notes
167        - fixed endless loop in Engine::SuspendAll() (bug #120)
168        - fixed a low-level atomic load function that was broken on 64-bit
169          PowerPC, which probably could cause crashes on that platform
170    
171    
172    Version 0.5.1 (6 December 2007)
173    
174      * packaging changes:
175        - added autoconf checks for pthread library
176        - added autoconf check for pthread bug found on certain NPTL-enabled
177          glibc versions (see Gentoo bug report #194076)
178        - added autoconf checks for MS Windows
179    
180      * general changes:
181        - bugfix: the thread used by an editor plugin didn't die when the
182          editor closed
183        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
184          out all the space. operator--() did not apply size_mask after
185          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
186          order to avoid problems with the _NonVolatileReader functions.
187        - bugfix: Stream.h: added a missing divide by BytesPerSample in
188          GetWriteSpace(). Since this function is currently only used in
189          the stream's qsort() compare function, it didn't trigger any
190          bugs.
191        - Resampler.h, Synthesizer.h: cubic interpolation now works in
192          24bit mode too. Faster method to read 24bit words on little
193          endian machines (x86): replaced 3 byte reads + shifts with a 1
194          unaligned 32bit read and shift
195        - experimental support for MS Windows (MIDI input via MME, AUDIO
196          output via ASIO)
197        - made handling of SIGINT signal (Ctrl-C) a bit more robust
198        - support for monitoring the total number of active disk streams
199          (new LSCP commands: GET TOTAL_STREAM_COUNT,
200          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
201    
202      * AUDIO driver:
203        - added Windows ASIO low latency audio driver
204    
205      * MIDI driver:
206        - added MME Windows MIDI driver
207    
208      * LSCP server:
209        - added support for Windows style path / filenames, however with
210          forward slash path separators instead of backslash
211          (i.e. "C:/foo/bar.gig")
212        - allow naughty liblscp to send non-string device parameters within
213          apostrophes as well
214        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
215          "LIST FILE INSTRUMENTS <file>" and
216          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
217          about an arbitrary instrument file on the system where the sampler is
218          running on
219
