1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3      * General changes:
4        - Refactoring: moved the independent code from
5          the Gigasampler format engine to base classes
6        - command line option '--profile' is currently disabled, since the
7          respective profiling code is currently broken
8        - Introduced support for optional environment variable
9          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
10          where the sampler shall look for instrument editor plugins
11          (patch by Luis Garrido, slightly modified).
12    
13      * Gigasampler format engine:
14        - implemented the "round robin keyboard" dimension
15        - fixed round robin and random dimensions for cases when number of
16          dimension zones is not a power of two
17        - made round robin use a counter for each region instead of each
18          key
19    
20      * SFZ format engine:
21        - Initial implementation (not usable yet)
22        - added support for v2 multiple stage envelope generators
23        - added a fine-tuned v1 envelope generator instead of using the
24          one from the gig engine
25        - fixed memory leak and memory handling errors
26        - added support for trigger=first, trigger=legato and sw_previous
27        - allow non-numerical key values ("C#4" for example)
28        - "key" opcode now sets pitch_keycenter too
29        - fixed error when unloading instrument with same sample used by
30          multiple regions
31        - added some opcode aliases, like loopmode for loop_mode, to be
32          more compatible
33        - added support for trigger=release and rt_decay
34        - added support for off_mode=normal
35        - added support for random, seq_position, seq_length and volume
36        - added v1 LFO opcodes to parser (no support in engine yet)
37        - added support for amp_veltrack and amp_velcurve_N
38        - fine-tuned the default velocity curve
39    
40      * SoundFont format engine:
41        - Initial implementation (not usable yet)
42    
43      * Host plugins:
44        - AU bugfix: failed to destroy its audio/MIDI devices
45        - Listen to all interfaces on Mac OS X (INADDR_ANY)
46        - VST bugfix: If the host called resume() before and after
47          changing sample rate or block size, the number of channels was
48          incorrectly set to two. This caused silence in Cubase 5.
49    
50      * MIDI driver:
51        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
52          the ALSA sequencer client name
53    
54      * LSCP server:
55        - added support for sending MIDI CC messages via LSCP command
56          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
57    
58      * Bug fixes:
59        - Fixed crash which may occur when MIDI key + transpose is out of range
60    
61    Version 1.0.0 (31 July 2009)

97        - fixed di-harmonic triangle LFO implementation (this LFO implementation
98          is only used by very few systems, most pick the int math
99          implementation, which is usually faster)
100        - fixes for audio drivers with varying buffer sizes
101        - experimental support for running LinuxSampler as a DSSI, LV2 and
102          VST plugin
103        - notification events for stream/voice count statistics are now sent
104          only when there are actual changes
105        - added memory ordering constraints to improve stability on
106          multi-core and multi-cpu systems
107        - maximum voices and disk streams can now be altered at runtime
108        - fixed CPU feature detection on x86_64 (maybe fixes #108)
109        - automatic stacktrace mechanism is now turned off by default and can
110          be switched on by command line option "--stacktrace" (the automatic
111          stacktrace mechanism seems to be broken on most systems at the moment)
112        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
113          a pointer to the launched InstrumentEditor object
114        - added optional 3rd party user data parameter for following
115          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
116          InstrumentEditor::Launch(),
117          InstrumentManager::LaunchInstrumentEditor()
118        - theoretical fix: made SynchronizedConfig follow C++0x memory
119          model more strictly
120        - fixes for using large audio device buffers
121        - Windows: add the installation directory to the DLL search path
122          when loading an editor plugin (solves problems with VST and

133        - Makefile fix: JACK_CFLAGS wasn't used
134        - JACK: use jack_client_open instead of the deprecated
135          jack_client_new
136        - added (experimental) CoreAudio driver
137        - applied old fixes to the ASIO driver that were included in the
138          previous binary release but accidentally never committed to CVS
139          (fixes #117)
140        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
141          win64)
142        - VST: added support for sample rate and buffer size changes
143        - VST: close editor (Fantasia) when the VST is removed
144        - VST: avoid opening Fantasia more than once for each VST instance

146          energyXT)
147        - VST: changed number of output channels from one stereo to 16
148          stereo
149        - added channel routing, fxsends and midi maps to the settings
150          stored in the plugin state
151        - performance optimization of AudioChannel::MixTo() and
152          AudioChannel::CopyTo() methods using GCC vector exensions
153          (if available)
154        - ASIO fixes: avoid initializing the device twice, avoid throwing
155          exception when getting parameters from a disconnected device
156    
157    * MIDI driver:    * MIDI driver:
158      - added JACK MIDI driver      - added JACK MIDI driver
159        - dispatch bank select as ordinary CC as well, the user might seriously
160          want to (mis)use it for some purpose ("fixed" in all current MIDI
161          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
162        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
163          CoreMidi or AU
164        - fixed mingw-w64 compilation error in MME driver
165        - made program change handling in MIDI thread real-time safe by
166          moving the logic to a non-RT thread

168    
169    * instruments database:    * instruments database:

171        to the instruments database        to the instruments database
172        - added support for handling lost files in the instruments database
173        - Implemented option for adding instruments in separate directories
174          in the instruments database
175          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
176        - work-around for missing fnmatch function on Windows to make
177          instrument database compilable
178        - added instrument database support on Windows
179          works with both standalone mode and VST plugin.
180          the instruments DB file is located in
181          %USERPROFILE%\.linuxsampler\instruments.db which allows different
182          databases for each windows user
183          if no DB is present it automatically creates the .linuxsampler subdir
184          and then creates an empty DB
185        - fixed recursive import, which was broken on Windows
186    
187    * Gigasampler format engine:    * Gigasampler format engine:
188      - fixed a memory leak that could happen when a channel was deleted      - fixed a memory leak that could happen when a channel was deleted
189        while notes were playing        while notes were playing
190      - made it possible to load an instrument even if the audio thread      - made it possible to load an instrument even if the audio thread
191        isn't running        isn't running
192        - added partial support for the "Controller Triggered" MIDI rule,
193          enough for piano gigs with pedal noise samples
194        - minor fix: only mark FX sends as being modified if really the
195          respective FX send MIDI controller was used
196        - added support for GM global device volume SysEx message
197          (can be selected at compile time to either apply globally to the
198          whole sampler [default] or only to the sampler channels that are
199          connected to the respective MIDI input port the SysEx message arrived
200          on)
201        - bugfix: notes triggered at position 0 in the audio buffer were
202          sometimes wrongly killed in the same buffer, causing no sound to
203          be played
204        - added support for chromatic / drumkit mode Roland GS Sysex message
205          which is usally used to switch a part between chromatic sounds and
206          drumkit sounds (as opposed to their common default setting of MIDI
207          part 10 being a drumkit part and all other ones chromatic parts), in
208          LS however one can switch between the first 16 MIDI instrument maps
209          defined for the sampler
210        - made it possible to create multiple sample channels even if the
211          audio thread isn't running
212        - fixed crash when removing channel with active voices (#116)
213        - bugfix: on sample reference changes (instrument editor), only
214          un-cache the respective sample if it's really not used by any
215          sampler engine anymore
216        - re-cache samples in case they were changed by an instrument editor,
217          e.g. when a sample was added while playing (#82)
218        - fixed hanging notes which occured when note-off event had the exact
219          same time stamp as the voice's note-on event and occured both in the
220          same audio fragment cycle (fixes bug #112)
221        - added support for the "fine tune" and "pitch bend range"
222          instrument-level gig parameters
223        - fixed minor artifacts in pitch bend handling
224        - added support for GS Reset SysEx message
225        - allow gig files to use unlimited downward pitch shifting
226        - added a limit check for upward pitch shifting
227        - bugfix: sometimes, when playing a note twice fast, the second
228          note was silent
229        - fixed crash happening when a pitch bend event arrived at the
230          same time a new instrument was loading
231    
232      * LSCP server:
233        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
234          react on MIDI data arriving on certain sampler channels (so far only
235          Note-On and Note-Off events are sent via this LSCP event)
236        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
237          react on MIDI data arriving on certain MIDI input devices (so far only
238          Note-On and Note-Off events are sent via this LSCP event)
239        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
240          SET DB_INSTRUMENT FILE_PATH
241        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
242          frontends to send MIDI messages to specific sampler channel
243        - added two additional fields to GET FILE INSTRUMENT INFO command -
244          KEY_BINDINGS and KEYSWITCH_BINDINGS
245        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
246          was incorrect
247        - Optimized the retrieval of the MIDI instrument mappings
248        - added new LSCP command "SET VOICES" to globally alter the maximum
249          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
250          be triggered respectively
251        - added new LSCP command "SET STREAMS" to globally alter the maximum
252          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
253          which will be triggered respectively
254        - bugfix: retry if "select" returns EINTR (this fixes a crash when
255          a gigedit file dialog is opened)
256        - close all connections when LSCPServer is deleted
257        - hard close of all sockets on exit
258        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
259          driver
260    
261      * Bug fixes:
262        - fixed a crash which occurs when removing a sampler channel waiting
263          to start instrument loading after another channel
264        - fixed a crash which occurs when removing a sampler channel with
265          instrument loading in progress (bug #113)
266        - fixed termination caused by uncaught exception when adding MIDI
267          instrument with PERSISTENT load mode
268        - fixed possible iterator invalidations when resetting the sampler
269        - fixed memory leaks when issuing the following LSCP commands:
270          GET AUDIO_OUTPUT_DRIVER INFO
271          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
272          GET MIDI_INPUT_DRIVER INFO
273          GET MIDI_INPUT_DRIVER_PARAMETER INFO
274        - fixed possible compilation error when sqlite is not present
275        - fixed orphaned pointers when setting maximum voices limit (bug #118)
276        - fixed crash when changing the audio output device of a sampler
277          channel with loaded instrument and start playing notes
278        - fixed endless loop in Engine::SuspendAll() (bug #120)
279        - fixed a low-level atomic load function that was broken on 64-bit
280          PowerPC, which probably could cause crashes on that platform
281        - fixed a memory management error which could cause a crash when a
282          plugin was unloaded
283        - bugfix: two private structs had the same name, which could cause
284          problems if the linker chose the wrong constructor
285        - fixed low-level ConditionServer usage bug that caused lockups on
286          Windows
