# Line 1  Line 1 
1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3      * host plugins:
4        - AU bugfix: failed to destroy its audio/MIDI devices
5        - Listen to all interfaces on Mac OS X (INADDR_ANY)
6    
7      * MIDI driver:
8        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
9          the ALSA sequencer client name
10    
11    Version 1.0.0 (31 July 2009)
12    
13      * packaging changes:
14        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
15          causing e.g. the libgig test to fail when
16          "./configure --disable-jack-driver" was used
17          (patch by Alexis Ballier)
18        - fixed compilation with gcc 4.3
19        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
20        - fixed configure so it detects x86_64 (#107)
21        - fixes for building with newer MinGW versions
22        - fix for building with bison 2.4 (#111)
23        - fixed building with libgig installed in a non-standard directory
24        - minor fix in configure for mmsystem.h detection on MinGW
25        - Windows: look for editor plugins and Fantasia using base
26          directory of liblinuxsampler dll (look in the same directory and one
27          directory above)
28        - configure script fix: removed unconditional use of SSE
29        - fixed building with sqlite installed in a non-standard directory
30        - when cross-compiling, don't try to create instruments.db
31        - fix for new mingw-w64 version, which has usleep
32    
33      * general changes:
34        - bugfix: on some POSIX systems instrument editor plugins refused to
35          load as we used a non-portable Linux specific struct field
36          (fixes bug #70, patch by Ronald Baljeu)
37        - fixed endless loop which occured when loading an instrument editor
38          plugin DLL on Windows systems failed
39        - fixed memory leaks that occurred when liblinuxsampler was unloaded
40        - optimized the SynchronizedConfig class so it doesn't wait
41          unnecessarily long after an update
42        - added support for notifying instrument editors on note-on / note-off
43          events (e.g. to highlight the pressed keys on the virtual keyboard
44          of gigedit)
45        - added support for triggering notes by instrument editors (see above)
46        - be verbose on DLL load errors (on Linux)
47        - fixed di-harmonic triangle LFO implementation (this LFO implementation
48          is only used by very few systems, most pick the int math
49          implementation, which is usually faster)
50        - fixes for audio drivers with varying buffer sizes
51        - experimental support for running LinuxSampler as a DSSI, LV2 and
52          VST plugin
53        - notification events for stream/voice count statistics are now sent
54          only when there are actual changes
55        - added memory ordering constraints to improve stability on
56          multi-core and multi-cpu systems
57        - maximum voices and disk streams can now be altered at runtime
58        - fixed CPU feature detection on x86_64 (maybe fixes #108)
59        - automatic stacktrace mechanism is now turned off by default and can
60          be switched on by command line option "--stacktrace" (the automatic
61          stacktrace mechanism seems to be broken on most systems at the moment)
62        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
63          a pointer to the launched InstrumentEditor object
64        - added optional 3rd party user data parameter for following
65          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
66          InstrumentEditor::Launch(),
67          InstrumentManager::LaunchInstrumentEditor()
68        - theoretical fix: made SynchronizedConfig follow C++0x memory
69          model more strictly
70        - fixes for using large audio device buffers
71        - Windows: add the installation directory to the DLL search path
72          when loading an editor plugin (solves problems with VST and
73          gigedit on systems with other GTK versions installed)
74    
75      * audio driver:
76        - removed the nonsense audio channel constraint (which was hard coded to
77          max. 100 audio channels) for most audio drivers
78        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
79          opposed to the LSCP specs
80        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
81          reflected the wrong value
82        - fixed a memory management bug in ASIO driver
83        - Makefile fix: JACK_CFLAGS wasn't used
84        - JACK: use jack_client_open instead of the deprecated
85          jack_client_new
86        - added (experimental) CoreAudio driver
87        - applied old fixes to the ASIO driver that were included in the
88          previous binary release but accidentally never committed to CVS
89          (fixes #117)
90        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
91          win64)
92        - VST: added support for sample rate and buffer size changes
93        - VST: close editor (Fantasia) when the VST is removed
94        - VST: avoid opening Fantasia more than once for each VST instance
95        - VST: export main function as "main" on Linux too (fix for
96          energyXT)
97        - VST: changed number of output channels from one stereo to 16
98          stereo
99        - added channel routing, fxsends and midi maps to the settings
100          stored in the plugin state
101        - performance optimization of AudioChannel::MixTo() and
102          AudioChannel::CopyTo() methods using GCC vector exensions
103          (if available)
104        - ASIO fixes: avoid initializing the device twice, avoid throwing
105          exception when getting parameters from a disconnected device
106    
107      * MIDI driver:
108        - added JACK MIDI driver
109        - dispatch bank select as ordinary CC as well, the user might seriously
110          want to (mis)use it for some purpose ("fixed" in all current MIDI
111          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
112        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
113          CoreMidi or AU
114        - fixed mingw-w64 compilation error in MME driver
115        - made program change handling in MIDI thread real-time safe by
116          moving the logic to a non-RT thread
117        - fixed minor memory leak in ALSA driver
118    
119      * instruments database:
120        - avoid time consuming samples scanning when adding instruments
121          to the instruments database
122        - added support for handling lost files in the instruments database
123        - Implemented option for adding instruments in separate directories
124          in the instruments database
125          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
126        - work-around for missing fnmatch function on Windows to make
127          instrument database compilable
128        - added instrument database support on Windows
129          works with both standalone mode and VST plugin.
130          the instruments DB file is located in
131          %USERPROFILE%\.linuxsampler\instruments.db which allows different
132          databases for each windows user
133          if no DB is present it automatically creates the .linuxsampler subdir
134          and then creates an empty DB
135        - fixed recursive import, which was broken on Windows
136    
137      * Gigasampler format engine:
138        - fixed a memory leak that could happen when a channel was deleted
139          while notes were playing
140        - made it possible to load an instrument even if the audio thread
141          isn't running
142        - added partial support for the "Controller Triggered" MIDI rule,
143          enough for piano gigs with pedal noise samples
144        - minor fix: only mark FX sends as being modified if really the
145          respective FX send MIDI controller was used
146        - added support for GM global device volume SysEx message
147          (can be selected at compile time to either apply globally to the
148          whole sampler [default] or only to the sampler channels that are
149          connected to the respective MIDI input port the SysEx message arrived
150          on)
151        - bugfix: notes triggered at position 0 in the audio buffer were
152          sometimes wrongly killed in the same buffer, causing no sound to
153          be played
154        - added support for chromatic / drumkit mode Roland GS Sysex message
155          which is usally used to switch a part between chromatic sounds and
156          drumkit sounds (as opposed to their common default setting of MIDI
157          part 10 being a drumkit part and all other ones chromatic parts), in
158          LS however one can switch between the first 16 MIDI instrument maps
159          defined for the sampler
160        - made it possible to create multiple sample channels even if the
161          audio thread isn't running
162        - fixed crash when removing channel with active voices (#116)
163        - bugfix: on sample reference changes (instrument editor), only
164          un-cache the respective sample if it's really not used by any
165          sampler engine anymore
166        - re-cache samples in case they were changed by an instrument editor,
167          e.g. when a sample was added while playing (#82)
168        - fixed hanging notes which occured when note-off event had the exact
169          same time stamp as the voice's note-on event and occured both in the
170          same audio fragment cycle (fixes bug #112)
171        - added support for the "fine tune" and "pitch bend range"
172          instrument-level gig parameters
173        - fixed minor artifacts in pitch bend handling
174        - added support for GS Reset SysEx message
175        - allow gig files to use unlimited downward pitch shifting
176        - added a limit check for upward pitch shifting
177        - bugfix: sometimes, when playing a note twice fast, the second
178          note was silent
179        - fixed crash happening when a pitch bend event arrived at the
180          same time a new instrument was loading
181    
182      * LSCP server:
183        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
184          react on MIDI data arriving on certain sampler channels (so far only
185          Note-On and Note-Off events are sent via this LSCP event)
186        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
187          react on MIDI data arriving on certain MIDI input devices (so far only
188          Note-On and Note-Off events are sent via this LSCP event)
189        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
190          SET DB_INSTRUMENT FILE_PATH
191        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
192          frontends to send MIDI messages to specific sampler channel
193        - added two additional fields to GET FILE INSTRUMENT INFO command -
194          KEY_BINDINGS and KEYSWITCH_BINDINGS
195        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
196          was incorrect
197        - Optimized the retrieval of the MIDI instrument mappings
198        - added new LSCP command "SET VOICES" to globally alter the maximum
199          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
200          be triggered respectively
201        - added new LSCP command "SET STREAMS" to globally alter the maximum
202          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
203          which will be triggered respectively
204        - bugfix: retry if "select" returns EINTR (this fixes a crash when
205          a gigedit file dialog is opened)
206        - close all connections when LSCPServer is deleted
207        - hard close of all sockets on exit
208        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
209          driver
210    
211      * Bug fixes:
212        - fixed a crash which occurs when removing a sampler channel waiting
213          to start instrument loading after another channel
214        - fixed a crash which occurs when removing a sampler channel with
215          instrument loading in progress (bug #113)
216        - fixed termination caused by uncaught exception when adding MIDI
217          instrument with PERSISTENT load mode
218        - fixed possible iterator invalidations when resetting the sampler
219        - fixed memory leaks when issuing the following LSCP commands:
220          GET AUDIO_OUTPUT_DRIVER INFO
221          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
222          GET MIDI_INPUT_DRIVER INFO
223          GET MIDI_INPUT_DRIVER_PARAMETER INFO
224        - fixed possible compilation error when sqlite is not present
225        - fixed orphaned pointers when setting maximum voices limit (bug #118)
226        - fixed crash when changing the audio output device of a sampler
227          channel with loaded instrument and start playing notes
228        - fixed endless loop in Engine::SuspendAll() (bug #120)
229        - fixed a low-level atomic load function that was broken on 64-bit
230          PowerPC, which probably could cause crashes on that platform
231        - fixed a memory management error which could cause a crash when a
232          plugin was unloaded
233        - bugfix: two private structs had the same name, which could cause
234          problems if the linker chose the wrong constructor
235        - fixed low-level ConditionServer usage bug that caused lockups on
236          Windows
