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
56          one from the gig engine
57        - fixed memory leak and memory handling errors
58        - added support for trigger=first, trigger=legato and sw_previous
59        - allow non-numerical key values ("C#4" for example)

61        - fixed error when unloading instrument with same sample used by
62          multiple regions
63        - added some opcode aliases, like loopmode for loop_mode, to be
64          more compatible

66        - added support for off_mode=normal
67        - added support for random, seq_position, seq_length and volume
68        - added v1 LFO opcodes to parser (no support in engine yet)

74        - added more v1 aliases to parser
75        - reduced memory usage for sfz data
76        - RT-safeness: avoid malloc in audio thread
77        - fixed a bug that could cause voice stealing to fail
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
86          not set in sfz file
87        - implemeted filters. Filter types: lowpass, bandpass, bandreject
88          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
89          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,

92        - added support for velocity effect on amplifier envelope time
93          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
94          ampeg_vel2release)
95        - added support for EG hold (ampeg_hold)
96        - added support for sample offset (offset)

104        - initial implementation of cutoff filter
105    
106      * Gigasampler format engine:
107        - bugfix: pitch LFO controller "internal+aftertouch" was broken
108        - bugfix: filter keyboard tracking was broken
109        - filter performance fix (an unnecessary copy was made of the
110          filter parameters in each sub fragment)
111    
112      * Host plugins:
113        - AU bugfix: failed to destroy its audio/MIDI devices
114        - Listen to all interfaces on Mac OS X (INADDR_ANY)
115        - VST bugfix: If the host called resume() before and after
116          changing sample rate or block size, the number of channels was
117          incorrectly set to two. This caused silence in Cubase 5.
118        - save engine type (gig, sfz or sf2) in plugin state
119        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
120          64 bit Windows
121        - AU: changed number of output channels from one stereo to 16
122          stereo
123        - VST: made it possible to build the VST plugin for Mac
124        - AU: link AU plugin dynamically if --disable-shared isn't
125          specified

128        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
129          the ALSA sequencer client name
130        - removed limit of maximum amount of MIDI ports per MIDI device, since
131          there is no reason for this limit
132    
133      * audio driver:
134        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
135    
136      * LSCP server:
137        - added support for sending MIDI CC messages via LSCP command
138          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

160        - added LSCP command "APPEND SEND_EFFECT_CHAIN EFFECT <audio-device>
161          <effect-chain> <effect-instance>"
162        - added LSCP command "INSERT SEND_EFFECT_CHAIN EFFECT <audio-device>
163          <effect-chain> <effect-chain-pos> <effect-instance>"

172    
173      * Bug fixes:
174        - Fixed crash which may occur when MIDI key + transpose is out of range
175        - minor valgrind fixes
176        - fixed crash which occurred when changing an already deployed sampler
177          channel to a different engine type
178        - fixed crash when deleting a sampler channel or changing engine
179          type while an instrument load was in progress
180        - bugfix: playing a note while changing the instrument could cause
181          a crash, or give "Handing back unknown region" error messages
182        - bugfix: calling SET VOICES (which Fantasia does on start and
183          refresh) could cause instruments to be unloaded
184        - Mac OS X: fixed name collision of enum in EffectControl and
185          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
186        - Mac OS X: fixed hanging threads
187        - Windows: disabled the previous thread fix on non-Mac systems, as
188          it caused hanging threads on Windows
189        - Fixed possible crashes due to corrupted MIDI/audio device list
190          after MIDI/audio device creation failure
191    
192    Version 1.0.0 (31 July 2009)
193    
194      * packaging changes:
195        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
196          causing e.g. the libgig test to fail when
197          "./configure --disable-jack-driver" was used
198          (patch by Alexis Ballier)
199        - fixed compilation with gcc 4.3
200        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
201        - fixed configure so it detects x86_64 (#107)
202        - fixes for building with newer MinGW versions
203        - fix for building with bison 2.4 (#111)
204        - fixed building with libgig installed in a non-standard directory
205        - minor fix in configure for mmsystem.h detection on MinGW
206        - Windows: look for editor plugins and Fantasia using base
207          directory of liblinuxsampler dll (look in the same directory and one
208          directory above)
209        - configure script fix: removed unconditional use of SSE
210        - fixed building with sqlite installed in a non-standard directory
211        - when cross-compiling, don't try to create instruments.db
212        - fix for new mingw-w64 version, which has usleep
213    
214      * general changes:
215        - bugfix: on some POSIX systems instrument editor plugins refused to
216          load as we used a non-portable Linux specific struct field
217          (fixes bug #70, patch by Ronald Baljeu)
218        - fixed endless loop which occured when loading an instrument editor
219          plugin DLL on Windows systems failed
220        - fixed memory leaks that occurred when liblinuxsampler was unloaded
221        - optimized the SynchronizedConfig class so it doesn't wait
222          unnecessarily long after an update
223        - added support for notifying instrument editors on note-on / note-off
224          events (e.g. to highlight the pressed keys on the virtual keyboard
225          of gigedit)
226        - added support for triggering notes by instrument editors (see above)
227        - be verbose on DLL load errors (on Linux)
228        - fixed di-harmonic triangle LFO implementation (this LFO implementation
229          is only used by very few systems, most pick the int math
230          implementation, which is usually faster)
231        - fixes for audio drivers with varying buffer sizes
232        - experimental support for running LinuxSampler as a DSSI, LV2 and
233          VST plugin
234        - notification events for stream/voice count statistics are now sent
235          only when there are actual changes
236        - added memory ordering constraints to improve stability on
237          multi-core and multi-cpu systems
238        - maximum voices and disk streams can now be altered at runtime
239        - fixed CPU feature detection on x86_64 (maybe fixes #108)
240        - automatic stacktrace mechanism is now turned off by default and can
241          be switched on by command line option "--stacktrace" (the automatic
242          stacktrace mechanism seems to be broken on most systems at the moment)
243        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
244          a pointer to the launched InstrumentEditor object
245        - added optional 3rd party user data parameter for following
246          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
247          InstrumentEditor::Launch(),
248          InstrumentManager::LaunchInstrumentEditor()
249        - theoretical fix: made SynchronizedConfig follow C++0x memory
250          model more strictly
251        - fixes for using large audio device buffers
252        - Windows: add the installation directory to the DLL search path
253          when loading an editor plugin (solves problems with VST and
254          gigedit on systems with other GTK versions installed)
255    
256      * audio driver:
257        - removed the nonsense audio channel constraint (which was hard coded to
258          max. 100 audio channels) for most audio drivers
259        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
260          opposed to the LSCP specs
261        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
262          reflected the wrong value
263        - fixed a memory management bug in ASIO driver
264        - Makefile fix: JACK_CFLAGS wasn't used
265        - JACK: use jack_client_open instead of the deprecated
266          jack_client_new
267        - added (experimental) CoreAudio driver
268        - applied old fixes to the ASIO driver that were included in the
269          previous binary release but accidentally never committed to CVS
270          (fixes #117)
271        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
272          win64)
273        - VST: added support for sample rate and buffer size changes
274        - VST: close editor (Fantasia) when the VST is removed
275        - VST: avoid opening Fantasia more than once for each VST instance
276        - VST: export main function as "main" on Linux too (fix for
277          energyXT)
278        - VST: changed number of output channels from one stereo to 16
279          stereo
280        - added channel routing, fxsends and midi maps to the settings
281          stored in the plugin state
282        - performance optimization of AudioChannel::MixTo() and
283          AudioChannel::CopyTo() methods using GCC vector exensions
284          (if available)
285        - ASIO fixes: avoid initializing the device twice, avoid throwing
286          exception when getting parameters from a disconnected device
287    
288      * MIDI driver:
289        - added JACK MIDI driver
290        - dispatch bank select as ordinary CC as well, the user might seriously
291          want to (mis)use it for some purpose ("fixed" in all current MIDI
292          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
293        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
294          CoreMidi or AU
295        - fixed mingw-w64 compilation error in MME driver
296        - made program change handling in MIDI thread real-time safe by
297          moving the logic to a non-RT thread
298        - fixed minor memory leak in ALSA driver
299    
300      * instruments database:
301        - avoid time consuming samples scanning when adding instruments
302          to the instruments database
303        - added support for handling lost files in the instruments database
304        - Implemented option for adding instruments in separate directories
305          in the instruments database
306          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
307        - work-around for missing fnmatch function on Windows to make
308          instrument database compilable
309        - added instrument database support on Windows
310          works with both standalone mode and VST plugin.
311          the instruments DB file is located in
312          %USERPROFILE%\.linuxsampler\instruments.db which allows different
313          databases for each windows user
314          if no DB is present it automatically creates the .linuxsampler subdir
315          and then creates an empty DB
316        - fixed recursive import, which was broken on Windows
317    
318      * Gigasampler format engine:
319        - fixed a memory leak that could happen when a channel was deleted
320          while notes were playing
321        - made it possible to load an instrument even if the audio thread
322          isn't running
323        - added partial support for the "Controller Triggered" MIDI rule,
324          enough for piano gigs with pedal noise samples
325        - minor fix: only mark FX sends as being modified if really the
326          respective FX send MIDI controller was used
327        - added support for GM global device volume SysEx message
328          (can be selected at compile time to either apply globally to the
329          whole sampler [default] or only to the sampler channels that are
330          connected to the respective MIDI input port the SysEx message arrived
331          on)
332        - bugfix: notes triggered at position 0 in the audio buffer were
333          sometimes wrongly killed in the same buffer, causing no sound to
334          be played
335        - added support for chromatic / drumkit mode Roland GS Sysex message
336          which is usally used to switch a part between chromatic sounds and
337          drumkit sounds (as opposed to their common default setting of MIDI
338          part 10 being a drumkit part and all other ones chromatic parts), in
339          LS however one can switch between the first 16 MIDI instrument maps
340          defined for the sampler
341        - made it possible to create multiple sample channels even if the
342          audio thread isn't running
343        - fixed crash when removing channel with active voices (#116)
344        - bugfix: on sample reference changes (instrument editor), only
345          un-cache the respective sample if it's really not used by any
346          sampler engine anymore
347        - re-cache samples in case they were changed by an instrument editor,
348          e.g. when a sample was added while playing (#82)
349        - fixed hanging notes which occured when note-off event had the exact
350          same time stamp as the voice's note-on event and occured both in the
351          same audio fragment cycle (fixes bug #112)
352        - added support for the "fine tune" and "pitch bend range"
353          instrument-level gig parameters
354        - fixed minor artifacts in pitch bend handling
355        - added support for GS Reset SysEx message
356        - allow gig files to use unlimited downward pitch shifting
357        - added a limit check for upward pitch shifting
358        - bugfix: sometimes, when playing a note twice fast, the second
359          note was silent
360        - fixed crash happening when a pitch bend event arrived at the
361          same time a new instrument was loading
362    
363      * LSCP server:
364        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
365          react on MIDI data arriving on certain sampler channels (so far only
366          Note-On and Note-Off events are sent via this LSCP event)
367        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
368          react on MIDI data arriving on certain MIDI input devices (so far only
369          Note-On and Note-Off events are sent via this LSCP event)
370        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
371          SET DB_INSTRUMENT FILE_PATH
372        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
373          frontends to send MIDI messages to specific sampler channel
374        - added two additional fields to GET FILE INSTRUMENT INFO command -
375          KEY_BINDINGS and KEYSWITCH_BINDINGS
376        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
377          was incorrect
378        - Optimized the retrieval of the MIDI instrument mappings
379        - added new LSCP command "SET VOICES" to globally alter the maximum
380          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
381          be triggered respectively
382        - added new LSCP command "SET STREAMS" to globally alter the maximum
383          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
384          which will be triggered respectively
385        - bugfix: retry if "select" returns EINTR (this fixes a crash when
386          a gigedit file dialog is opened)
387        - close all connections when LSCPServer is deleted
388        - hard close of all sockets on exit
389        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
390          driver
391    
392      * Bug fixes:
393        - fixed a crash which occurs when removing a sampler channel waiting
394          to start instrument loading after another channel
395        - fixed a crash which occurs when removing a sampler channel with
396          instrument loading in progress (bug #113)
397        - fixed termination caused by uncaught exception when adding MIDI
398          instrument with PERSISTENT load mode
399        - fixed possible iterator invalidations when resetting the sampler
400        - fixed memory leaks when issuing the following LSCP commands:
401          GET AUDIO_OUTPUT_DRIVER INFO
402          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
403          GET MIDI_INPUT_DRIVER INFO
404          GET MIDI_INPUT_DRIVER_PARAMETER INFO
405        - fixed possible compilation error when sqlite is not present
406        - fixed orphaned pointers when setting maximum voices limit (bug #118)
407        - fixed crash when changing the audio output device of a sampler
408          channel with loaded instrument and start playing notes
409        - fixed endless loop in Engine::SuspendAll() (bug #120)
410        - fixed a low-level atomic load function that was broken on 64-bit
411          PowerPC, which probably could cause crashes on that platform
412        - fixed a memory management error which could cause a crash when a
413          plugin was unloaded
414        - bugfix: two private structs had the same name, which could cause
415          problems if the linker chose the wrong constructor
416        - fixed low-level ConditionServer usage bug that caused lockups on
417          Windows
418    
419    
420    Version 0.5.1 (6 December 2007)
421    
422      * packaging changes:
423        - added autoconf checks for pthread library
424        - added autoconf check for pthread bug found on certain NPTL-enabled
425          glibc versions (see Gentoo bug report #194076)
426        - added autoconf checks for MS Windows
427    
428      * general changes:
429        - bugfix: the thread used by an editor plugin didn't die when the
430          editor closed
431        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
432          out all the space. operator--() did not apply size_mask after
433          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
434          order to avoid problems with the _NonVolatileReader functions.
435        - bugfix: Stream.h: added a missing divide by BytesPerSample in
436          GetWriteSpace(). Since this function is currently only used in
437          the stream's qsort() compare function, it didn't trigger any
438          bugs.
439        - Resampler.h, Synthesizer.h: cubic interpolation now works in
440          24bit mode too. Faster method to read 24bit words on little
441          endian machines (x86): replaced 3 byte reads + shifts with a 1
442          unaligned 32bit read and shift
443        - experimental support for MS Windows (MIDI input via MME, AUDIO
444          output via ASIO)
445        - made handling of SIGINT signal (Ctrl-C) a bit more robust
446        - support for monitoring the total number of active disk streams
447          (new LSCP commands: GET TOTAL_STREAM_COUNT,
448          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
449    
450      * AUDIO driver:
451        - added Windows ASIO low latency audio driver
452    
453      * MIDI driver:
454        - added MME Windows MIDI driver
455    
456      * LSCP server:
457        - added support for Windows style path / filenames, however with
458          forward slash path separators instead of backslash
459          (i.e. "C:/foo/bar.gig")
460        - allow naughty liblscp to send non-string device parameters within
461          apostrophes as well
462        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
463          "LIST FILE INSTRUMENTS <file>" and
464          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
465          about an arbitrary instrument file on the system where the sampler is
466          running on
467    
468    Version 0.5.0 (15 October 2007)
469    
470    * packaging changes:    * packaging changes:
471        - config.h is not going to be installed along with liblinuxsampler's
472          API header files anymore
473        - only the API relevant header (and source) files will be exported to
474          the Doxygen API documentation (explicitly listed in Doxyfile.in)
475        - added completely new XCode project files for Mac OSX which is now
476          capable to execute our autoconf environment, thus no need anymore
477          to maintain the compile time configuration file (osx/version.h) for
478          OSX manually (patch by Toshi Nagata)
479        - fixed buggy boolean --enable-foo / --disable-foo configure script
480          parameters
481        - global.h now only covers global definitions that are needed for the
482          C++ API header files, all implementation internal global definitions
483          are now in global_private.h
484        - atomic.h is not exposed to the C++ API anymore
485        - no need to include config.h anymore for using LS's API header files
486        - fixed warnings in API doc generation
487    
488      * general changes:
489        - replaced the old, confusing MIDI program change mechanism by a
490          flexible MIDI instrument mapper which allows to map arbitrary
491          (MIDI bank, MIDI program) pairs with arbitrary
492          (engine type, instrument file, file index) triplets which will be
493          loaded on the respective channel when such MIDI program change
494          messages arrive, beside that, each entry allows to define a life-time
495          strategy for the instrument, so the user can define whether the
496          instrument should i.e. be permanently loaded (to be able to switch
497          quickly among sounds) or i.e. loaded just on demand when the
498          respective program change arrives (to safe RAM space), as well as a
499          global volume factor for each entry, so the user can adjust the volume
500          dynamic of his mapped instrument collection without having to modify
501          the instrument files, also one can manage arbitrary amount of such
502          MIDI instrument maps and assign each sampler channel individually
503          a certain map, so that i.e. separation of normal instruments and
504          drumkits is possible
505        - new notification events for tracking changes to audio/MIDI devices,
506          MIDI instrument maps, MIDI instruments, FX sends, global volume.
507        - sampler was limited to load max. 200 instruments in the background
508          due to a constant size RingBuffer FIFO which is now replaced by a
509          dynamic (unlimited) size std::list FIFO
510        - added FX sends, these allow to route audio signals to arbitrary audio
511          output channels for being processed by external effect processors
512          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
513          controllers
514        - global (sampler wide) volume can now be controlled at runtime
515        - Implemented new, improved notification system
516        - fixed compilation errors regarding OSX
517          (patch by Toshi Nagata)
518        - implemented instruments database
519        - added support for escape sequences to the instruments database
520        - added highly experimental support for on-the-fly instrument editing
521          within the sampler's process (by using instrument editor plugins),
522          you'll notice the new "Registered instrument editors:" message on
523          startup, added a new LSCP command:
524          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
525          to spawn a matching instrument editor for the instrument on the
526          given sampler channel, the plugin path can be overridden at compile
527          time with ./configure --enable-plugin-dir=/some/dir
528        - added experimental code for synchronizing instrument editors hosted
529          in the sampler's process to safely edit instruments while playing
530          without a crash (hopefully) by either suspending single regions
531          wherever possible or if unavoidable whole engine(s)
532        - fixed several issues in fundamental "Thread" class: set scheduling
533          policy and priority on thread level, set a minimum stack size for
534          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
535          threads simply inherited properties of starting thread instead of
536          setting their own policy and priority
537        - minor fix in our automatic stack trace mechanism on crashes, the
538          main process did not wait for the stack trace process to finish
539          its output
540        - fixed some minor memory leaks
541        - reenabled assembly features support, at the moment only for
542          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
543        - minor assembly fix in x86 features detection (don't use the PIC
544          register, to avoid relocations in the text segment at runtime)
545        - POSIX callback functions of Thread.h are hidden
546    
547      * MIDI driver:
548        - dispatch bank select (MSB and LSB) messages
549    
550      * audio driver:
551        - the ALSA audio output driver parameters now reflect the correct
552          parameter value ranges for the respective selected sound card
553          (patch by Till Wimmer, a bit fixed and extended)
554    
555      * Gigasampler format engine:
556        - if a filter is used and EG2 finishes before EG1, let the voice
557          die when EG2 has finished (this fixes a problem with clicks and
558          voice starvation for some gigs)
559        - playback is no longer disabled during instrument loading
560        - all notes playing on a channel that changes its instrument keep
561          playing with the old instrument until they get a note off
562          command
563        - EG fix: a release value of zero could cause noises or crash
564        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
565        - EG fine tuning: when attack is zero the EG starts at a level
566          above max sustain level, which means that there is a decay phase
567          even if sustain is 100%
568        - more EG fixes: the level could sometimes go below zero and cause
569          noises or crashes
570        - minor fix of EGDecay (patch by Toshi Nagata)
571        - fixed compiler error when --enable-override-filter-type was
572          supplied to the configure script (fixes #46)
573        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
574          instead of a fix value
575        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
576          127 (solo mode) only kill voices if the respective mode really
577          changed
578    
579      * LSCP server:
580        - fixed compile time error for old Bison versions
581          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
582        - parser now supports extended ASCII character set
583          (up to ASCII code 255, i.e. includes now umlauts and accents)
584        - filename arguments in LSCP commands now allow to use escape
585          sequences, that is directly literal as one of: \', \", \\, \n, \r,
586          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
587          code value like \xf2) (fixes bug #24)
588        - the following LSCP commands now also support escape sequences for at
589          least one of their text-based parameters (i.e. name, description):
590          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
591          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
592          "SET DB_INSTRUMENT_DIRECTORY NAME",
593          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
594          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
595          "FIND DB_INSTRUMENT_DIRECTORIES"
596        - returns verbose syntax errors (line and column where syntax error
597          occured, the unexpected character and the actually expected, possible
598          character(s), the latter only if less than 5 possibilities)
599        - made sure that LSCP syntax is not affected by gigedit locale
600          settings
601        - bugfix regarding strings parameter lists: all comma separated lists
602          of strings were treated as being one string containing commas
603          (fixes #57)
604    
605      * Bug fixes:
606        - fixed crash occurring on certain LSCP scripts (Bug 39)
607        - another thread safety fix for lscp "load engine" and "set
608          channel audio output device"
609        - fixed a crash which occurs when reassigning the same engine
610          on a sampler channel with connected MIDI device
611        - fixed a crash which occurs when changing the number of ports of a MIDI
612          device connected to a sampler channel to number less then or equal
613          to the index of the port to which the sampler channel is connected.
614        - The previous bindings were not been disconnected when altering
615          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
616          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
617        - The active stream/voice count statistic was incorrect.
618        - notification events were not been sent for some sampler
619          channel changes
620        - added default min and max values to restrict the number of allowed
621          audio output channels and MIDI input ports
622        - the connection to the PCM interface is now closed when destroying
623          an audio output device
624        - files with slash in their path or filename could not be loaded
625    
626      * test cases:
627        - updated and fixed (haven't been touched in a while)
628    
629    Version 0.4.0 (24 November 2006)
630    
631      * packaging changes:
632        - changed deprecated copyright attribute to license; added ldconfig
633          to post-(un)install steps; added devel package for liblinuxsampler;
634          to linuxsampler.spec (RPM)
635      - install necessary development header files for allowing 3rd party      - install necessary development header files for allowing 3rd party
636        applications to link against liblinuxsampler        applications to link against liblinuxsampler
637      - liblinuxsampler's API documentation can be generated with 'make docs'      - liblinuxsampler's API documentation can be generated with 'make docs'
638        (Doxygen required)        (Doxygen required)
639        - added benchmark to automatically detect the best triangle LFO
640          implementation (currently either an integer math solution or a
641          di-harmonic approximation), automatic detection can be overriden
642          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
643          configure script argument though (mandatory for cross-compilation)
644        - do not automatically pick optimized gcc flags if the user already
645          provided some on his own (as CXXFLAGS)
646        - added compile time option to disable processing of All-Notes-Off MIDI
647          messages
648        - added compile time options to allow disabling the various audio and
649          MIDI drivers
650        - fixed automatic GCC CPU switch detection on PPC
651          (patch by Ebrahim Mayat)
652    
653    * Gigasampler format engine:    * Gigasampler format engine:
654        - extensive synthesis optimization
655          (reimplementation of EGs and LFO(s), removed synthesis parameter
656          prerendering and the synthesis parameter matrix in general, splitting
657          each audio fragment into subfragments now where each subfragment uses
658          constant pitch and filter coefficients. The volume coefficient is
659          linearly interpolated inside a subfragment, unless
660          --disable-interpolate-volume is set.)
661      - fine tuning of the EG modulation parameters      - fine tuning of the EG modulation parameters
662        - improved filter cutoff calculation by adding support for the
663          following gig parameters: Cutoff freq (used when no cutoff
664          controller is defined), Control invert, Minimum cutoff, Velocity
665          curve and Velocity range. The keyboard tracking now scales
666          cutoff frequency instead of resonance.
667        - added support for gig parameter Resonance.
668        - fixed bug in sysex handling (patch by Juan Linietsky)
669        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
670          which can be overridden with --enable-global-attenuation
671        - EG fixes: made the length of "attack hold" stage more
672          accurate. Release stage can now start before attack stage
673          ends. Cancel release didn't work when sustain was zero. Attack
674          time now has a minimal value to prevent clicks.
675        - fixed pitch changes larger than one octave
676        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
677        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
678          all modes can be altered via standard GM messages, that is CC5 for
679          altering portamento time, CC65 for enabling / disabling portamento
680          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
681        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
682          parameter) and crossfade
683        - added support for the "attenuation controller threshold" gig
684          parameter
685        - added smoothing of volume changes caused by control change
686          messages
687        - sample loop parameters are now taken from the DimensionRegion
688          instead of the wave chunk
689        - fixed keyswitching for v3 gigs with a number of keyswitch splits
690          not equal to a power of two
691        - reimplementation of the filter algorithm. The new filter is more
692          accurate and supports all gig filter types, including bandreject
693          and lowpass turbo.
694        - real support for 24 bit samples - samples are not truncated to
695          16 bits anymore
696        - support for aftertouch (channel pressure, not polyphonic
697          aftertouch)
698        - LFO1 behaviour fixed (dampening from max volume instead of
699          amplifying from 0)
700    
701      * LSCP server:
702        - fixed application exit on broken pipe error (fixes bug #20)
703        - fixed the notification messages delay due to lack of
704          network activity (fixes bug #26)
705        - fixed parser bug which occured on space(s) within device parameters
706          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
707    
708      * audio driver:
709        - added aRts audio output driver (by no means RT safe)
710    
711      * MIDI driver:
712        - fixed legacy sysex code which caused dispatching of MIDI SysEx
713          messages several times instead of once
714        - API extension for MIDI drivers which already supply exact time stamps
715          for events (i.e. for offline rendering based MIDI drivers)
716        - added checks for bad MIDI data
717    
718      * linuxsampler application:
719        - show available sampler engine types on startup
720    
721    * general changes:    * general changes:
722      - support for muting sampler channels and solo mode of the same, two new      - support for muting sampler channels and solo mode of the same, two new
723        LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new        LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
724        fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were        fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
725        introduced for this, the behavior is the same like on a mixer console        introduced for this, the behavior is the same like on a mixer console
726        (patch by Grigor Iliev, a bit adjusted)        (patch by Grigor Iliev, a bit adjusted). Also added configure option
727          --enable-process-muted-channels which can be used to enable the
728          processing of muted channels.
729        - support for sostenuto pedal
730        - support for monitoring the total number of active voices
731          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
732          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
733        - fixed some memory management errors
734        - fixed some concurrency problems that could lead to crashes when
735          LSCP commands were executed
736        - fixed crash when instrument loading failed previously on the same
737          sampler channel (fixes bug #36)
