2    
3      * plugin changes:
4        - LV2 Persist + Files support (patch by David Robillard)
5    
6      * packaging changes:
7        - fixed building with newer MinGW-w64
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)
44

47        - fixed round robin and random dimensions for cases when number of
48          dimension zones is not a power of two
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

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

112    
113      * SoundFont format engine:

119        - initial implementation of cutoff filter
120    
121      * Gigasampler format engine:
122        - bugfix: pitch LFO controller "internal+aftertouch" was broken
123        - bugfix: filter keyboard tracking was broken
124        - filter performance fix (an unnecessary copy was made of the

126    
127      * Host plugins:
128        - AU bugfix: failed to destroy its audio/MIDI devices
129        - Listen to all interfaces on Mac OS X (INADDR_ANY)
130        - VST bugfix: If the host called resume() before and after
131          changing sample rate or block size, the number of channels was
132          incorrectly set to two. This caused silence in Cubase 5.
133        - save engine type (gig, sfz or sf2) in plugin state
134        - VST: when opening Fantasia, look for both 32 and 64 bit Java on

143        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
144          the ALSA sequencer client name
145        - removed limit of maximum amount of MIDI ports per MIDI device, since
146          there is no reason for this limit
147    
148      * audio driver:
149        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
150    
151      * LSCP server:

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

425        - fixed a low-level atomic load function that was broken on 64-bit
426          PowerPC, which probably could cause crashes on that platform
427        - fixed a memory management error which could cause a crash when a
428          plugin was unloaded
429        - bugfix: two private structs had the same name, which could cause
430          problems if the linker chose the wrong constructor
431        - fixed low-level ConditionServer usage bug that caused lockups on
432          Windows
433    
434    
435    Version 0.5.1 (6 December 2007)
436    
437      * packaging changes:
438        - added autoconf checks for pthread library
439        - added autoconf check for pthread bug found on certain NPTL-enabled
440          glibc versions (see Gentoo bug report #194076)
441        - added autoconf checks for MS Windows
442    
443      * general changes:
444        - bugfix: the thread used by an editor plugin didn't die when the
445          editor closed
446        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
447          out all the space. operator--() did not apply size_mask after
448          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
449          order to avoid problems with the _NonVolatileReader functions.
450        - bugfix: Stream.h: added a missing divide by BytesPerSample in
451          GetWriteSpace(). Since this function is currently only used in
452          the stream's qsort() compare function, it didn't trigger any
453          bugs.
454        - Resampler.h, Synthesizer.h: cubic interpolation now works in
455          24bit mode too. Faster method to read 24bit words on little
456          endian machines (x86): replaced 3 byte reads + shifts with a 1
457          unaligned 32bit read and shift
458        - experimental support for MS Windows (MIDI input via MME, AUDIO
459          output via ASIO)
460        - made handling of SIGINT signal (Ctrl-C) a bit more robust
461        - support for monitoring the total number of active disk streams
462          (new LSCP commands: GET TOTAL_STREAM_COUNT,
463          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
464    
465      * AUDIO driver:
466        - added Windows ASIO low latency audio driver
467    
468      * MIDI driver:
469        - added MME Windows MIDI driver
470    
471      * LSCP server:
472        - added support for Windows style path / filenames, however with
473          forward slash path separators instead of backslash
474          (i.e. "C:/foo/bar.gig")
475        - allow naughty liblscp to send non-string device parameters within
476          apostrophes as well
477        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
478          "LIST FILE INSTRUMENTS <file>" and
479          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
480          about an arbitrary instrument file on the system where the sampler is
481          running on
482    
483    Version 0.5.0 (15 October 2007)
484    
485      * packaging changes:
486        - config.h is not going to be installed along with liblinuxsampler's
487          API header files anymore
488        - only the API relevant header (and source) files will be exported to
489          the Doxygen API documentation (explicitly listed in Doxyfile.in)
490        - added completely new XCode project files for Mac OSX which is now
491          capable to execute our autoconf environment, thus no need anymore
492          to maintain the compile time configuration file (osx/version.h) for
493          OSX manually (patch by Toshi Nagata)
494        - fixed buggy boolean --enable-foo / --disable-foo configure script
495          parameters
496        - global.h now only covers global definitions that are needed for the
497          C++ API header files, all implementation internal global definitions
498          are now in global_private.h
499        - atomic.h is not exposed to the C++ API anymore
500        - no need to include config.h anymore for using LS's API header files
501        - fixed warnings in API doc generation

531        - fixed compilation errors regarding OSX
532          (patch by Toshi Nagata)
533        - implemented instruments database
534        - added support for escape sequences to the instruments database
535        - added highly experimental support for on-the-fly instrument editing
536          within the sampler's process (by using instrument editor plugins),
537          you'll notice the new "Registered instrument editors:" message on
538          startup, added a new LSCP command:
539          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
540          to spawn a matching instrument editor for the instrument on the
541          given sampler channel, the plugin path can be overridden at compile
542          time with ./configure --enable-plugin-dir=/some/dir
543        - added experimental code for synchronizing instrument editors hosted
544          in the sampler's process to safely edit instruments while playing
545          without a crash (hopefully) by either suspending single regions
546          wherever possible or if unavoidable whole engine(s)
547        - fixed several issues in fundamental "Thread" class: set scheduling
548          policy and priority on thread level, set a minimum stack size for
549          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
550          threads simply inherited properties of starting thread instead of
551          setting their own policy and priority
552        - minor fix in our automatic stack trace mechanism on crashes, the
553          main process did not wait for the stack trace process to finish
554          its output
555        - fixed some minor memory leaks
556        - reenabled assembly features support, at the moment only for
557          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
558        - minor assembly fix in x86 features detection (don't use the PIC
559          register, to avoid relocations in the text segment at runtime)
560        - POSIX callback functions of Thread.h are hidden
561

579      - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)      - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
580        - EG fine tuning: when attack is zero the EG starts at a level
581          above max sustain level, which means that there is a decay phase
582          even if sustain is 100%
583        - more EG fixes: the level could sometimes go below zero and cause
584          noises or crashes
585        - minor fix of EGDecay (patch by Toshi Nagata)
586        - fixed compiler error when --enable-override-filter-type was
587          supplied to the configure script (fixes #46)
588        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
589          instead of a fix value
590        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
591          127 (solo mode) only kill voices if the respective mode really
592          changed
593    
594      * LSCP server:
595        - fixed compile time error for old Bison versions
596          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
597        - parser now supports extended ASCII character set
598          (up to ASCII code 255, i.e. includes now umlauts and accents)
599        - filename arguments in LSCP commands now allow to use escape
600          sequences, that is directly literal as one of: \', \", \\, \n, \r,
601          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
602          code value like \xf2) (fixes bug #24)
603        - the following LSCP commands now also support escape sequences for at
604          least one of their text-based parameters (i.e. name, description):
605          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
606          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
607          "SET DB_INSTRUMENT_DIRECTORY NAME",
608          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
609          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
610          "FIND DB_INSTRUMENT_DIRECTORIES"
611        - returns verbose syntax errors (line and column where syntax error
612          occured, the unexpected character and the actually expected, possible
613          character(s), the latter only if less than 5 possibilities)
614        - made sure that LSCP syntax is not affected by gigedit locale
615          settings
616        - bugfix regarding strings parameter lists: all comma separated lists
617          of strings were treated as being one string containing commas
618          (fixes #57)
619

624        - fixed a crash which occurs when reassigning the same engine
625          on a sampler channel with connected MIDI device
626        - fixed a crash which occurs when changing the number of ports of a MIDI
627          device connected to a sampler channel to number less then or equal
628          to the index of the port to which the sampler channel is connected.
629        - The previous bindings were not been disconnected when altering
630          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
631          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
632        - The active stream/voice count statistic was incorrect.
633        - notification events were not been sent for some sampler
634          channel changes
635        - added default min and max values to restrict the number of allowed
636          audio output channels and MIDI input ports
637        - the connection to the PCM interface is now closed when destroying
638          an audio output device
639        - files with slash in their path or filename could not be loaded
