1  Version CVS HEAD (?)  Version 1.0.0 (30 July 2009)
2    
3      * 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

14        - minor fix in configure for mmsystem.h detection on MinGW
15        - Windows: look for editor plugins and Fantasia using base
16          directory of liblinuxsampler dll (look in the same directory and one
17          directory above)
18        - configure script fix: removed unconditional use of SSE
19        - fixed building with sqlite installed in a non-standard directory
20        - when cross-compiling, don't try to create instruments.db
21        - fix for new mingw-w64 version, which has usleep
22

28        plugin DLL on Windows systems failed        plugin DLL on Windows systems failed
29        - fixed memory leaks that occurred when liblinuxsampler was unloaded
30        - optimized the SynchronizedConfig class so it doesn't wait
31          unnecessarily long after an update
32        - added support for notifying instrument editors on note-on / note-off
33          events (e.g. to highlight the pressed keys on the virtual keyboard
34          of gigedit)
35        - added support for triggering notes by instrument editors (see above)
36        - be verbose on DLL load errors (on Linux)
37        - fixed di-harmonic triangle LFO implementation (this LFO implementation
38          is only used by very few systems, most pick the int math
39          implementation, which is usually faster)
40        - fixes for audio drivers with varying buffer sizes
41        - experimental support for running LinuxSampler as a DSSI, LV2 and
42          VST plugin
43        - notification events for stream/voice count statistics are now sent
44          only when there are actual changes
45        - added memory ordering constraints to improve stability on
46          multi-core and multi-cpu systems
47        - maximum voices and disk streams can now be altered at runtime
48        - fixed CPU feature detection on x86_64 (maybe fixes #108)
49        - automatic stacktrace mechanism is now turned off by default and can
50          be switched on by command line option "--stacktrace" (the automatic
51          stacktrace mechanism seems to be broken on most systems at the moment)
52        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
53          a pointer to the launched InstrumentEditor object
54        - added optional 3rd party user data parameter for following
55          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
56          InstrumentEditor::Launch(),
57          InstrumentManager::LaunchInstrumentEditor()
58        - theoretical fix: made SynchronizedConfig follow C++0x memory
59          model more strictly
60        - fixes for using large audio device buffers
61        - Windows: add the installation directory to the DLL search path
62          when loading an editor plugin (solves problems with VST and
63          gigedit on systems with other GTK versions installed)

71        reflected the wrong value        reflected the wrong value
72        - fixed a memory management bug in ASIO driver
73        - Makefile fix: JACK_CFLAGS wasn't used
74        - JACK: use jack_client_open instead of the deprecated
75          jack_client_new
76        - added (experimental) CoreAudio driver
77        - applied old fixes to the ASIO driver that were included in the
78          previous binary release but accidentally never committed to CVS
79          (fixes #117)
80        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
81          win64)
82        - VST: added support for sample rate and buffer size changes
83        - VST: close editor (Fantasia) when the VST is removed
84        - VST: avoid opening Fantasia more than once for each VST instance
85        - VST: export main function as "main" on Linux too (fix for
86          energyXT)
87        - VST: changed number of output channels from one stereo to 16
88          stereo
89        - added channel routing, fxsends and midi maps to the settings
90          stored in the plugin state
91        - performance optimization of AudioChannel::MixTo() and
92          AudioChannel::CopyTo() methods using GCC vector exensions
93          (if available)
94        - ASIO fixes: avoid initializing the device twice, avoid throwing
95          exception when getting parameters from a disconnected device
96    
97      * MIDI driver:
98        - added JACK MIDI driver
99        - dispatch bank select as ordinary CC as well, the user might seriously
100          want to (mis)use it for some purpose ("fixed" in all current MIDI
101          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
102        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
103          CoreMidi or AU
104        - fixed mingw-w64 compilation error in MME driver
105        - made program change handling in MIDI thread real-time safe by
106          moving the logic to a non-RT thread
107        - fixed minor memory leak in ALSA driver
108    
109    * instruments database:    * instruments database:
110      - avoid time consuming samples scanning when adding instruments      - avoid time consuming samples scanning when adding instruments
111        to the instruments database        to the instruments database
112        - added support for handling lost files in the instruments database
113        - Implemented option for adding instruments in separate directories
114          in the instruments database
115          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
116        - work-around for missing fnmatch function on Windows to make
117          instrument database compilable
118        - added instrument database support on Windows
119          works with both standalone mode and VST plugin.
120          the instruments DB file is located in
121          %USERPROFILE%\.linuxsampler\instruments.db which allows different
122          databases for each windows user
123          if no DB is present it automatically creates the .linuxsampler subdir
124          and then creates an empty DB
125        - fixed recursive import, which was broken on Windows
126    
127      * Gigasampler format engine:
128        - fixed a memory leak that could happen when a channel was deleted
129          while notes were playing
130        - made it possible to load an instrument even if the audio thread
131          isn't running
132        - added partial support for the "Controller Triggered" MIDI rule,
133          enough for piano gigs with pedal noise samples
134        - minor fix: only mark FX sends as being modified if really the
135          respective FX send MIDI controller was used
136        - added support for GM global device volume SysEx message
137          (can be selected at compile time to either apply globally to the
138          whole sampler [default] or only to the sampler channels that are
139          connected to the respective MIDI input port the SysEx message arrived
140          on)
141        - bugfix: notes triggered at position 0 in the audio buffer were
142          sometimes wrongly killed in the same buffer, causing no sound to
143          be played
144        - added support for chromatic / drumkit mode Roland GS Sysex message
145          which is usally used to switch a part between chromatic sounds and
146          drumkit sounds (as opposed to their common default setting of MIDI
147          part 10 being a drumkit part and all other ones chromatic parts), in
148          LS however one can switch between the first 16 MIDI instrument maps
149          defined for the sampler
150        - made it possible to create multiple sample channels even if the
151          audio thread isn't running
152        - fixed crash when removing channel with active voices (#116)
153        - bugfix: on sample reference changes (instrument editor), only
154          un-cache the respective sample if it's really not used by any
155          sampler engine anymore
156        - re-cache samples in case they were changed by an instrument editor,
157          e.g. when a sample was added while playing (#82)
158        - fixed hanging notes which occured when note-off event had the exact
159          same time stamp as the voice's note-on event and occured both in the
160          same audio fragment cycle (fixes bug #112)
161        - added support for the "fine tune" and "pitch bend range"
162          instrument-level gig parameters
163        - fixed minor artifacts in pitch bend handling
164        - added support for GS Reset SysEx message
165        - allow gig files to use unlimited downward pitch shifting
166        - added a limit check for upward pitch shifting
167        - bugfix: sometimes, when playing a note twice fast, the second
168          note was silent
169        - fixed crash happening when a pitch bend event arrived at the
170          same time a new instrument was loading
171    
172      * LSCP server:
173        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
174          react on MIDI data arriving on certain sampler channels (so far only
175          Note-On and Note-Off events are sent via this LSCP event)
176        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
177          react on MIDI data arriving on certain MIDI input devices (so far only
178          Note-On and Note-Off events are sent via this LSCP event)
179        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
180          SET DB_INSTRUMENT FILE_PATH
181        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
182          frontends to send MIDI messages to specific sampler channel
183        - added two additional fields to GET FILE INSTRUMENT INFO command -
184          KEY_BINDINGS and KEYSWITCH_BINDINGS
185        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
186          was incorrect
187        - Optimized the retrieval of the MIDI instrument mappings
188        - added new LSCP command "SET VOICES" to globally alter the maximum
189          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
190          be triggered respectively
191        - added new LSCP command "SET STREAMS" to globally alter the maximum
192          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
193          which will be triggered respectively
194        - bugfix: retry if "select" returns EINTR (this fixes a crash when
195          a gigedit file dialog is opened)
196        - close all connections when LSCPServer is deleted
197        - hard close of all sockets on exit
198        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
199          driver
200    
201      * Bug fixes:
202        - fixed a crash which occurs when removing a sampler channel waiting
203          to start instrument loading after another channel
204        - fixed a crash which occurs when removing a sampler channel with
205          instrument loading in progress (bug #113)
206        - fixed termination caused by uncaught exception when adding MIDI
207          instrument with PERSISTENT load mode
208        - fixed possible iterator invalidations when resetting the sampler
209        - fixed memory leaks when issuing the following LSCP commands:
210          GET AUDIO_OUTPUT_DRIVER INFO
211          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
212          GET MIDI_INPUT_DRIVER INFO
213          GET MIDI_INPUT_DRIVER_PARAMETER INFO
214        - fixed possible compilation error when sqlite is not present
215        - fixed orphaned pointers when setting maximum voices limit (bug #118)
216        - fixed crash when changing the audio output device of a sampler
217          channel with loaded instrument and start playing notes
218        - fixed endless loop in Engine::SuspendAll() (bug #120)
219        - fixed a low-level atomic load function that was broken on 64-bit
220          PowerPC, which probably could cause crashes on that platform
221        - fixed a memory management error which could cause a crash when a
222          plugin was unloaded
223        - bugfix: two private structs had the same name, which could cause
224          problems if the linker chose the wrong constructor
225        - fixed low-level ConditionServer usage bug that caused lockups on
226          Windows
