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        - 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        - minor fix in configure for mmsystem.h detection on MinGW
15    
16      * general changes:
17        - bugfix: on some POSIX systems instrument editor plugins refused to
18          load as we used a non-portable Linux specific struct field
19          (fixes bug #70, patch by Ronald Baljeu)
20        - fixed endless loop which occured when loading an instrument editor
21          plugin DLL on Windows systems failed
22        - fixed memory leaks that occurred when liblinuxsampler was unloaded
23        - optimized the SynchronizedConfig class so it doesn't wait
24          unnecessarily long after an update
25        - added support for notifying instrument editors on note-on / note-off
26          events (e.g. to highlight the pressed keys on the virtual keyboard
27          of gigedit)
28        - added support for triggering notes by instrument editors (see above)
29        - be verbose on DLL load errors (on Linux)
30        - fixed di-harmonic triangle LFO implementation (this LFO implementation
31          is only used by very few systems, most pick the int math
32          implementation, which is usually faster)
33        - fixes for audio drivers with varying buffer sizes
34        - experimental support for running LinuxSampler as a DSSI, LV2 and
35          VST plugin
36        - notification events for stream/voice count statistics are now sent
37          only when there are actual changes
38        - added memory ordering constraints to improve stability on
39          multi-core and multi-cpu systems
40        - maximum voices and disk streams can now be altered at runtime
41        - fixed CPU feature detection on x86_64 (maybe fixes #108)
42        - automatic stacktrace mechanism is now turned off by default and can
43          be switched on by command line option "--stacktrace" (the automatic
44          stacktrace mechanism seems to be broken on most systems at the moment)
45        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
46          a pointer to the launched InstrumentEditor object
47        - added optional 3rd party user data parameter for following
48          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
49          InstrumentEditor::Launch(),
50          InstrumentManager::LaunchInstrumentEditor()
51        - theoretical fix: made SynchronizedConfig follow C++0x memory
52          model more strictly
53        - fixes for using large audio device buffers
54    
55      * audio driver:
56        - removed the nonsense audio channel constraint (which was hard coded to
57          max. 100 audio channels) for most audio drivers
58        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
59          opposed to the LSCP specs
60        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
61          reflected the wrong value
62        - fixed a memory management bug in ASIO driver
63        - Makefile fix: JACK_CFLAGS wasn't used
64        - JACK: use jack_client_open instead of the deprecated
65          jack_client_new
66        - added (experimental) CoreAudio driver
67        - applied old fixes to the ASIO driver that were included in the
68          previous binary release but accidentally never committed to CVS
69          (fixes #117)
70        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
71          win64)
72        - VST: added support for sample rate and buffer size changes
73        - VST: close editor (Fantasia) when the VST is removed
74    
75      * MIDI driver:
76        - added JACK MIDI driver
77        - dispatch bank select as ordinary CC as well, the user might seriously
78          want to (mis)use it for some purpose ("fixed" in all current MIDI
79          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
80        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
81          CoreMidi or AU
82        - fixed mingw-w64 compilation error in MME driver
83    
84      * instruments database:
85        - avoid time consuming samples scanning when adding instruments
86          to the instruments database
87        - added support for handling lost files in the instruments database
88        - Implemented option for adding instruments in separate directories
89          in the instruments database
90          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
91    
92      * Gigasampler format engine:
93        - fixed a memory leak that could happen when a channel was deleted
94          while notes were playing
95        - made it possible to load an instrument even if the audio thread
96          isn't running
97        - added partial support for the "Controller Triggered" MIDI rule,
98          enough for piano gigs with pedal noise samples
99        - minor fix: only mark FX sends as being modified if really the
100          respective FX send MIDI controller was used
101        - added support for GM global device volume SysEx message
102          (can be selected at compile time to either apply globally to the
103          whole sampler [default] or only to the sampler channels that are
104          connected to the respective MIDI input port the SysEx message arrived
105          on)
106        - bugfix: notes triggered at position 0 in the audio buffer were
107          sometimes wrongly killed in the same buffer, causing no sound to
108          be played
109        - added support for chromatic / drumkit mode Roland GS Sysex message
110          which is usally used to switch a part between chromatic sounds and
111          drumkit sounds (as opposed to their common default setting of MIDI
112          part 10 being a drumkit part and all other ones chromatic parts), in
113          LS however one can switch between the first 16 MIDI instrument maps
114          defined for the sampler
115        - made it possible to create multiple sample channels even if the
116          audio thread isn't running
117        - fixed crash when removing channel with active voices (#116)
118        - bugfix: on sample reference changes (instrument editor), only
119          un-cache the respective sample if it's really not used by any
120          sampler engine anymore
121        - re-cache samples in case they were changed by an instrument editor,
122          e.g. when a sample was added while playing (#82)
123        - fixed hanging notes which occured when note-off event had the exact
124          same time stamp as the voice's note-on event and occured both in the
125          same audio fragment cycle (fixes bug #112)
126        - added support for the "fine tune" and "pitch bend range"
127          instrument-level gig parameters
128        - fixed minor artifacts in pitch bend handling
129        - added support for GS Reset SysEx message
130        - allow gig files to use unlimited downward pitch shifting
131        - added a limit check for upward pitch shifting
132    
133      * LSCP server:
134        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
135          react on MIDI data arriving on certain sampler channels (so far only
136          Note-On and Note-Off events are sent via this LSCP event)
137        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
138          react on MIDI data arriving on certain MIDI input devices (so far only
139          Note-On and Note-Off events are sent via this LSCP event)
140        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
141          SET DB_INSTRUMENT FILE_PATH
142        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
143          frontends to send MIDI messages to specific sampler channel
144        - added two additional fields to GET FILE INSTRUMENT INFO command -
145          KEY_BINDINGS and KEYSWITCH_BINDINGS
146        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
147          was incorrect
148        - Optimized the retrieval of the MIDI instrument mappings
149        - added new LSCP command "SET VOICES" to globally alter the maximum
150          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
151          be triggered respectively
152        - added new LSCP command "SET STREAMS" to globally alter the maximum
153          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
154          which will be triggered respectively
155        - bugfix: retry if "select" returns EINTR (this fixes a crash when
156          a gigedit file dialog is opened)
157        - close all connections when LSCPServer is deleted
158        - hard close of all sockets on exit
159    
160      * Bug fixes:
161        - fixed a crash which occurs when removing a sampler channel waiting
162          to start instrument loading after another channel
163        - fixed a crash which occurs when removing a sampler channel with
164          instrument loading in progress (bug #113)
165        - fixed termination caused by uncaught exception when adding MIDI
166          instrument with PERSISTENT load mode
167        - fixed possible iterator invalidations when resetting the sampler
168        - fixed memory leaks when issuing the following LSCP commands:
169          GET AUDIO_OUTPUT_DRIVER INFO
170          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
171          GET MIDI_INPUT_DRIVER INFO
172          GET MIDI_INPUT_DRIVER_PARAMETER INFO
173        - fixed possible compilation error when sqlite is not present
174        - fixed orphaned pointers when setting maximum voices limit (bug #118)
175        - fixed crash when changing the audio output device of a sampler
176          channel with loaded instrument and start playing notes
177        - fixed endless loop in Engine::SuspendAll() (bug #120)
178        - fixed a low-level atomic load function that was broken on 64-bit
179          PowerPC, which probably could cause crashes on that platform
180        - fixed a memory management error which could cause a crash when a
181          plugin was unloaded
182        - bugfix: two private structs had the same name, which could cause
183          problems if the linker chose the wrong constructor
184    
185    
186    Version 0.5.1 (6 December 2007)
187    
188      * packaging changes:
189        - added autoconf checks for pthread library
190        - added autoconf check for pthread bug found on certain NPTL-enabled
191          glibc versions (see Gentoo bug report #194076)
192        - added autoconf checks for MS Windows
193    
194      * general changes:
195        - bugfix: the thread used by an editor plugin didn't die when the
196          editor closed
197        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
198          out all the space. operator--() did not apply size_mask after
199          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
200          order to avoid problems with the _NonVolatileReader functions.
201        - bugfix: Stream.h: added a missing divide by BytesPerSample in
202          GetWriteSpace(). Since this function is currently only used in
203          the stream's qsort() compare function, it didn't trigger any
204          bugs.
205        - Resampler.h, Synthesizer.h: cubic interpolation now works in
206          24bit mode too. Faster method to read 24bit words on little
207          endian machines (x86): replaced 3 byte reads + shifts with a 1
208          unaligned 32bit read and shift
209        - experimental support for MS Windows (MIDI input via MME, AUDIO
210          output via ASIO)
211        - made handling of SIGINT signal (Ctrl-C) a bit more robust
212        - support for monitoring the total number of active disk streams
213          (new LSCP commands: GET TOTAL_STREAM_COUNT,
214          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
215    
216      * AUDIO driver:
217        - added Windows ASIO low latency audio driver
218    
219      * MIDI driver:
220        - added MME Windows MIDI driver
221    
222      * LSCP server:
223        - added support for Windows style path / filenames, however with
224          forward slash path separators instead of backslash
225          (i.e. "C:/foo/bar.gig")
226        - allow naughty liblscp to send non-string device parameters within
227          apostrophes as well
228        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
229          "LIST FILE INSTRUMENTS <file>" and
230          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
231          about an arbitrary instrument file on the system where the sampler is
232          running on
233    
234    Version 0.5.0 (15 October 2007)
