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).

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)

47        - implemented the "round robin keyboard" dimension
48        - fixed round robin and random dimensions for cases when number of
49          dimension zones is not a power of two
50        - made round robin use a counter for each region instead of each
51          key
52    
53      * SFZ format engine:
54        - Initial implementation (not usable yet)
55        - added support for v2 multiple stage envelope generators
56        - added a fine-tuned v1 envelope generator instead of using the

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

160          the ALSA sequencer client name
161        - removed limit of maximum amount of MIDI ports per MIDI device, since
162          there is no reason for this limit
163    
164      * audio driver:
165        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
166

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

392          same time a new instrument was loading
393    
394      * LSCP server:
395        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
396          react on MIDI data arriving on certain sampler channels (so far only
397          Note-On and Note-Off events are sent via this LSCP event)
398        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to

417          a gigedit file dialog is opened)
418        - close all connections when LSCPServer is deleted
419        - hard close of all sockets on exit
420        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
421          driver
422    
423      * Bug fixes:
424        - fixed a crash which occurs when removing a sampler channel waiting
425          to start instrument loading after another channel
426        - fixed a crash which occurs when removing a sampler channel with

437        - fixed orphaned pointers when setting maximum voices limit (bug #118)
438        - fixed crash when changing the audio output device of a sampler
439          channel with loaded instrument and start playing notes
440        - fixed endless loop in Engine::SuspendAll() (bug #120)
441        - fixed a low-level atomic load function that was broken on 64-bit
442          PowerPC, which probably could cause crashes on that platform
443        - fixed a memory management error which could cause a crash when a
444          plugin was unloaded
445        - bugfix: two private structs had the same name, which could cause
446          problems if the linker chose the wrong constructor
447        - fixed low-level ConditionServer usage bug that caused lockups on

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

551        - added highly experimental support for on-the-fly instrument editing
552          within the sampler's process (by using instrument editor plugins),
553          you'll notice the new "Registered instrument editors:" message on
554          startup, added a new LSCP command:
555          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
556          to spawn a matching instrument editor for the instrument on the
557          given sampler channel, the plugin path can be overridden at compile
558          time with ./configure --enable-plugin-dir=/some/dir
559        - added experimental code for synchronizing instrument editors hosted
560          in the sampler's process to safely edit instruments while playing
561          without a crash (hopefully) by either suspending single regions
562          wherever possible or if unavoidable whole engine(s)
563        - fixed several issues in fundamental "Thread" class: set scheduling
564          policy and priority on thread level, set a minimum stack size for
565          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
566          threads simply inherited properties of starting thread instead of
567          setting their own policy and priority
568        - minor fix in our automatic stack trace mechanism on crashes, the
569          main process did not wait for the stack trace process to finish
570          its output
571        - fixed some minor memory leaks
572        - reenabled assembly features support, at the moment only for
573          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
574        - minor assembly fix in x86 features detection (don't use the PIC
575          register, to avoid relocations in the text segment at runtime)
576        - POSIX callback functions of Thread.h are hidden
577

601        - minor fix of EGDecay (patch by Toshi Nagata)
602        - fixed compiler error when --enable-override-filter-type was
603          supplied to the configure script (fixes #46)
604        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
605          instead of a fix value
606        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
607          127 (solo mode) only kill voices if the respective mode really
608          changed
609    
610      * LSCP server:
611        - fixed compile time error for old Bison versions
612          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
613        - parser now supports extended ASCII character set
614          (up to ASCII code 255, i.e. includes now umlauts and accents)
615        - filename arguments in LSCP commands now allow to use escape
616          sequences, that is directly literal as one of: \', \", \\, \n, \r,
617          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
618          code value like \xf2) (fixes bug #24)
619        - the following LSCP commands now also support escape sequences for at
620          least one of their text-based parameters (i.e. name, description):
621          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
622          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
623          "SET DB_INSTRUMENT_DIRECTORY NAME",

625          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
626          "FIND DB_INSTRUMENT_DIRECTORIES"
627        - returns verbose syntax errors (line and column where syntax error
628          occured, the unexpected character and the actually expected, possible
629          character(s), the latter only if less than 5 possibilities)
630        - made sure that LSCP syntax is not affected by gigedit locale
631          settings
632        - bugfix regarding strings parameter lists: all comma separated lists
633          of strings were treated as being one string containing commas
634          (fixes #57)

641          on a sampler channel with connected MIDI device
642        - fixed a crash which occurs when changing the number of ports of a MIDI
643          device connected to a sampler channel to number less then or equal
644          to the index of the port to which the sampler channel is connected.
645        - The previous bindings were not been disconnected when altering
646          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
647          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
648        - The active stream/voice count statistic was incorrect.
649        - notification events were not been sent for some sampler
650          channel changes
651        - added default min and max values to restrict the number of allowed
652          audio output channels and MIDI input ports
653        - the connection to the PCM interface is now closed when destroying
654          an audio output device
