1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3      * plugin changes:
4        - LV2 Persist + Files support (patch by David Robillard)
5    
6      * packaging changes:

8        - Mac OS X: support the new dir for Core Audio SDK
9        - Mac OS X: fixed building outside source directory
10        - made sure all source files for hostplugins are included when
11          doing "make dist"
12        - removed empty directories left from the cvs to svn migration
13        - fixed compilation with gcc 4.6.1
14        - another "make dist" fix, for the LV2 plugin
15        - made --enable-pthread-testcancel default on Mac OS X
16        - minor Makefile fix for building lscpparser when build and source
17          directories are separate
18        - Mac OS X: made it possible to specify plugin installation dir to
19          configure
20        - Mac OS X: Makefile fix for the install-strip target
21    
22      * general changes:
23        - Refactoring: moved the independent code from
24          the Gigasampler format engine to base classes
25        - command line option '--profile' is currently disabled, since the
26          respective profiling code is currently broken
27        - Introduced support for optional environment variable
28          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
29          where the sampler shall look for instrument editor plugins
30          (patch by Luis Garrido, slightly modified).
31        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
32        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
33        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
34          note (in this implementation of the sampler its simply hard routed to
35          the 1st effect send of the sampler channel, no matter what the actual
36          effect type is)
37        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38          note (in this implementation of the sampler its simply hard routed to
39          the 2nd effect send of the sampler channel, no matter what the actual
40          effect type is)
41        - implemented support for internal LADSPA effects
42        - raised limit of program change queue from 100 to 512
43          (as suggested by Alex Stone)

49        - made round robin use a counter for each region instead of each
50          key
51    
52      * SFZ format engine:
53        - Initial implementation (not usable yet)
54        - added support for v2 multiple stage envelope generators
55        - added a fine-tuned v1 envelope generator instead of using the
56          one from the gig engine

78        - optimized sample lookup
79        - improved support for exclusive groups (group, off_by and
80          off_mode)
81        - added support for controller triggered regions (on_locc/on_hicc)
82        - added support for loop_mode=one_shot
83        - fixed playback of 16 bit wav files on big endian CPUs
84        - added support for Ogg Vorbis sample files
85        - use loop markers from sample file if loop_start and loop_end are

112        - initial implementation of cutoff filter
113    
114      * Gigasampler format engine:
115        - bugfix: pitch LFO controller "internal+aftertouch" was broken
116        - bugfix: filter keyboard tracking was broken
117        - filter performance fix (an unnecessary copy was made of the
118          filter parameters in each sub fragment)
119    
120      * Host plugins:
121        - AU bugfix: failed to destroy its audio/MIDI devices
122        - Listen to all interfaces on Mac OS X (INADDR_ANY)
123        - VST bugfix: If the host called resume() before and after
124          changing sample rate or block size, the number of channels was
125          incorrectly set to two. This caused silence in Cubase 5.
126        - save engine type (gig, sfz or sf2) in plugin state
127        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
128          64 bit Windows
129        - AU: changed number of output channels from one stereo to 16
130          stereo
131        - VST: made it possible to build the VST plugin for Mac
132        - AU: link AU plugin dynamically if --disable-shared isn't
133          specified
134    
135      * MIDI driver:
136        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
137          the ALSA sequencer client name
138        - removed limit of maximum amount of MIDI ports per MIDI device, since
139          there is no reason for this limit
140    
141      * audio driver:
142        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
143    
144      * LSCP server:
145        - added support for sending MIDI CC messages via LSCP command
146          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

168        - added LSCP command "APPEND SEND_EFFECT_CHAIN EFFECT <audio-device>
169          <effect-chain> <effect-instance>"
170        - added LSCP command "INSERT SEND_EFFECT_CHAIN EFFECT <audio-device>
171          <effect-chain> <effect-chain-pos> <effect-instance>"

181      * Bug fixes:
182        - Fixed crash which may occur when MIDI key + transpose is out of range
183        - minor valgrind fixes
184        - fixed crash which occurred when changing an already deployed sampler
185          channel to a different engine type
186        - fixed crash when deleting a sampler channel or changing engine
187          type while an instrument load was in progress
188        - bugfix: playing a note while changing the instrument could cause
189          a crash, or give "Handing back unknown region" error messages
190        - bugfix: calling SET VOICES (which Fantasia does on start and
191          refresh) could cause instruments to be unloaded
192        - Mac OS X: fixed name collision of enum in EffectControl and
193          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
194        - Mac OS X: fixed hanging threads
195        - Windows: disabled the previous thread fix on non-Mac systems, as
196          it caused hanging threads on Windows
197        - Fixed possible crashes due to corrupted MIDI/audio device list
198          after MIDI/audio device creation failure
199    
200    Version 1.0.0 (31 July 2009)
201    
202      * packaging changes:
203        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
204          causing e.g. the libgig test to fail when
205          "./configure --disable-jack-driver" was used
206          (patch by Alexis Ballier)
207        - fixed compilation with gcc 4.3
208        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
209        - fixed configure so it detects x86_64 (#107)
210        - fixes for building with newer MinGW versions
211        - fix for building with bison 2.4 (#111)
212        - fixed building with libgig installed in a non-standard directory
213        - minor fix in configure for mmsystem.h detection on MinGW
214        - Windows: look for editor plugins and Fantasia using base
215          directory of liblinuxsampler dll (look in the same directory and one
216          directory above)
217        - configure script fix: removed unconditional use of SSE
218        - fixed building with sqlite installed in a non-standard directory
219        - when cross-compiling, don't try to create instruments.db
220        - fix for new mingw-w64 version, which has usleep
221    
222      * general changes:
223        - bugfix: on some POSIX systems instrument editor plugins refused to
224          load as we used a non-portable Linux specific struct field
225          (fixes bug #70, patch by Ronald Baljeu)
226        - fixed endless loop which occured when loading an instrument editor
227          plugin DLL on Windows systems failed
228        - fixed memory leaks that occurred when liblinuxsampler was unloaded
229        - optimized the SynchronizedConfig class so it doesn't wait
230          unnecessarily long after an update
231        - added support for notifying instrument editors on note-on / note-off
232          events (e.g. to highlight the pressed keys on the virtual keyboard
233          of gigedit)
234        - added support for triggering notes by instrument editors (see above)
235        - be verbose on DLL load errors (on Linux)
236        - fixed di-harmonic triangle LFO implementation (this LFO implementation
237          is only used by very few systems, most pick the int math
238          implementation, which is usually faster)
239        - fixes for audio drivers with varying buffer sizes
240        - experimental support for running LinuxSampler as a DSSI, LV2 and
241          VST plugin
242        - notification events for stream/voice count statistics are now sent
243          only when there are actual changes
244        - added memory ordering constraints to improve stability on
245          multi-core and multi-cpu systems
246        - maximum voices and disk streams can now be altered at runtime
247        - fixed CPU feature detection on x86_64 (maybe fixes #108)
248        - automatic stacktrace mechanism is now turned off by default and can
249          be switched on by command line option "--stacktrace" (the automatic
250          stacktrace mechanism seems to be broken on most systems at the moment)
251        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
252          a pointer to the launched InstrumentEditor object
253        - added optional 3rd party user data parameter for following
254          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
255          InstrumentEditor::Launch(),
256          InstrumentManager::LaunchInstrumentEditor()
257        - theoretical fix: made SynchronizedConfig follow C++0x memory
258          model more strictly
259        - fixes for using large audio device buffers
260        - Windows: add the installation directory to the DLL search path
261          when loading an editor plugin (solves problems with VST and
262          gigedit on systems with other GTK versions installed)
263    
264      * audio driver:
265        - removed the nonsense audio channel constraint (which was hard coded to
266          max. 100 audio channels) for most audio drivers
267        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
268          opposed to the LSCP specs
269        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
270          reflected the wrong value
271        - fixed a memory management bug in ASIO driver
272        - Makefile fix: JACK_CFLAGS wasn't used
273        - JACK: use jack_client_open instead of the deprecated
274          jack_client_new
275        - added (experimental) CoreAudio driver
276        - applied old fixes to the ASIO driver that were included in the
277          previous binary release but accidentally never committed to CVS
278          (fixes #117)
279        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
280          win64)
281        - VST: added support for sample rate and buffer size changes
282        - VST: close editor (Fantasia) when the VST is removed
283        - VST: avoid opening Fantasia more than once for each VST instance
284        - VST: export main function as "main" on Linux too (fix for
285          energyXT)
286        - VST: changed number of output channels from one stereo to 16
287          stereo
288        - added channel routing, fxsends and midi maps to the settings
289          stored in the plugin state
290        - performance optimization of AudioChannel::MixTo() and
291          AudioChannel::CopyTo() methods using GCC vector exensions
292          (if available)
293        - ASIO fixes: avoid initializing the device twice, avoid throwing
294          exception when getting parameters from a disconnected device
295    
296      * MIDI driver:
297        - added JACK MIDI driver
298        - dispatch bank select as ordinary CC as well, the user might seriously
299          want to (mis)use it for some purpose ("fixed" in all current MIDI
300          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
301        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
302          CoreMidi or AU
303        - fixed mingw-w64 compilation error in MME driver
304        - made program change handling in MIDI thread real-time safe by
305          moving the logic to a non-RT thread
306        - fixed minor memory leak in ALSA driver
307    
308      * instruments database:
309        - avoid time consuming samples scanning when adding instruments
310          to the instruments database
311        - added support for handling lost files in the instruments database
312        - Implemented option for adding instruments in separate directories
313          in the instruments database
314          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
315        - work-around for missing fnmatch function on Windows to make
316          instrument database compilable
317        - added instrument database support on Windows
318          works with both standalone mode and VST plugin.
319          the instruments DB file is located in
320          %USERPROFILE%\.linuxsampler\instruments.db which allows different
321          databases for each windows user
322          if no DB is present it automatically creates the .linuxsampler subdir
323          and then creates an empty DB
324        - fixed recursive import, which was broken on Windows
325    
326      * Gigasampler format engine:
327        - fixed a memory leak that could happen when a channel was deleted
328          while notes were playing
329        - made it possible to load an instrument even if the audio thread
330          isn't running
331        - added partial support for the "Controller Triggered" MIDI rule,
332          enough for piano gigs with pedal noise samples
333        - minor fix: only mark FX sends as being modified if really the
334          respective FX send MIDI controller was used
335        - added support for GM global device volume SysEx message
336          (can be selected at compile time to either apply globally to the
337          whole sampler [default] or only to the sampler channels that are
338          connected to the respective MIDI input port the SysEx message arrived
339          on)
340        - bugfix: notes triggered at position 0 in the audio buffer were
341          sometimes wrongly killed in the same buffer, causing no sound to
342          be played
343        - added support for chromatic / drumkit mode Roland GS Sysex message
344          which is usally used to switch a part between chromatic sounds and
345          drumkit sounds (as opposed to their common default setting of MIDI
346          part 10 being a drumkit part and all other ones chromatic parts), in
347          LS however one can switch between the first 16 MIDI instrument maps
348          defined for the sampler
349        - made it possible to create multiple sample channels even if the
350          audio thread isn't running
351        - fixed crash when removing channel with active voices (#116)
352        - bugfix: on sample reference changes (instrument editor), only
353          un-cache the respective sample if it's really not used by any
354          sampler engine anymore
355        - re-cache samples in case they were changed by an instrument editor,
356          e.g. when a sample was added while playing (#82)
357        - fixed hanging notes which occured when note-off event had the exact
358          same time stamp as the voice's note-on event and occured both in the
359          same audio fragment cycle (fixes bug #112)
360        - added support for the "fine tune" and "pitch bend range"
361          instrument-level gig parameters
362        - fixed minor artifacts in pitch bend handling
363        - added support for GS Reset SysEx message
364        - allow gig files to use unlimited downward pitch shifting
365        - added a limit check for upward pitch shifting
366        - bugfix: sometimes, when playing a note twice fast, the second
367          note was silent
368        - fixed crash happening when a pitch bend event arrived at the
369          same time a new instrument was loading
370    
371      * LSCP server:
372        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
373          react on MIDI data arriving on certain sampler channels (so far only
374          Note-On and Note-Off events are sent via this LSCP event)
375        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
376          react on MIDI data arriving on certain MIDI input devices (so far only
377          Note-On and Note-Off events are sent via this LSCP event)
378        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
379          SET DB_INSTRUMENT FILE_PATH
380        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
381          frontends to send MIDI messages to specific sampler channel
382        - added two additional fields to GET FILE INSTRUMENT INFO command -
383          KEY_BINDINGS and KEYSWITCH_BINDINGS
384        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
385          was incorrect
386        - Optimized the retrieval of the MIDI instrument mappings
387        - added new LSCP command "SET VOICES" to globally alter the maximum
388          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
389          be triggered respectively
390        - added new LSCP command "SET STREAMS" to globally alter the maximum
391          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
392          which will be triggered respectively
393        - bugfix: retry if "select" returns EINTR (this fixes a crash when
394          a gigedit file dialog is opened)
395        - close all connections when LSCPServer is deleted
396        - hard close of all sockets on exit
397        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
398          driver
399    
400      * Bug fixes:
401        - fixed a crash which occurs when removing a sampler channel waiting
402          to start instrument loading after another channel
403        - fixed a crash which occurs when removing a sampler channel with
404          instrument loading in progress (bug #113)
405        - fixed termination caused by uncaught exception when adding MIDI
406          instrument with PERSISTENT load mode
407        - fixed possible iterator invalidations when resetting the sampler
408        - fixed memory leaks when issuing the following LSCP commands:
409          GET AUDIO_OUTPUT_DRIVER INFO
410          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
411          GET MIDI_INPUT_DRIVER INFO
412          GET MIDI_INPUT_DRIVER_PARAMETER INFO
413        - fixed possible compilation error when sqlite is not present
414        - fixed orphaned pointers when setting maximum voices limit (bug #118)
415        - fixed crash when changing the audio output device of a sampler
416          channel with loaded instrument and start playing notes
417        - fixed endless loop in Engine::SuspendAll() (bug #120)
418        - fixed a low-level atomic load function that was broken on 64-bit
419          PowerPC, which probably could cause crashes on that platform
420        - fixed a memory management error which could cause a crash when a
421          plugin was unloaded
422        - bugfix: two private structs had the same name, which could cause
423          problems if the linker chose the wrong constructor
424        - fixed low-level ConditionServer usage bug that caused lockups on
425          Windows
426    
427    
428    Version 0.5.1 (6 December 2007)
429    
430      * packaging changes:
431        - added autoconf checks for pthread library
432        - added autoconf check for pthread bug found on certain NPTL-enabled
433          glibc versions (see Gentoo bug report #194076)
434        - added autoconf checks for MS Windows
435    
436      * general changes:
437        - bugfix: the thread used by an editor plugin didn't die when the
438          editor closed
439        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
440          out all the space. operator--() did not apply size_mask after
441          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
442          order to avoid problems with the _NonVolatileReader functions.
443        - bugfix: Stream.h: added a missing divide by BytesPerSample in
444          GetWriteSpace(). Since this function is currently only used in
445          the stream's qsort() compare function, it didn't trigger any
446          bugs.
447        - Resampler.h, Synthesizer.h: cubic interpolation now works in
448          24bit mode too. Faster method to read 24bit words on little
449          endian machines (x86): replaced 3 byte reads + shifts with a 1
450          unaligned 32bit read and shift
451        - experimental support for MS Windows (MIDI input via MME, AUDIO
452          output via ASIO)
453        - made handling of SIGINT signal (Ctrl-C) a bit more robust
454        - support for monitoring the total number of active disk streams
455          (new LSCP commands: GET TOTAL_STREAM_COUNT,
456          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
457    
458      * AUDIO driver:
459        - added Windows ASIO low latency audio driver
460    
461      * MIDI driver:
462        - added MME Windows MIDI driver
463    
464      * LSCP server:
465        - added support for Windows style path / filenames, however with
466          forward slash path separators instead of backslash
467          (i.e. "C:/foo/bar.gig")
468        - allow naughty liblscp to send non-string device parameters within
469          apostrophes as well
470        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
471          "LIST FILE INSTRUMENTS <file>" and
472          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
473          about an arbitrary instrument file on the system where the sampler is
474          running on
