3    * packaging changes:    * packaging changes:
4        - fixed building with newer MinGW-w64
5    
6      * general changes:
7        - Refactoring: moved the independent code from
8          the Gigasampler format engine to base classes
9        - command line option '--profile' is currently disabled, since the
10          respective profiling code is currently broken
11        - Introduced support for optional environment variable
12          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
13          where the sampler shall look for instrument editor plugins
14          (patch by Luis Garrido, slightly modified).
15        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
16        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
17        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
18          note (in this implementation of the sampler its simply hard routed to
19          the 1st effect send of the sampler channel, no matter what the actual
20          effect type is)
21        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
22          note (in this implementation of the sampler its simply hard routed to
23          the 2nd effect send of the sampler channel, no matter what the actual
24          effect type is)
25        - implemented support for internal LADSPA effects
26    
27      * Gigasampler format engine:
28        - implemented the "round robin keyboard" dimension
29        - fixed round robin and random dimensions for cases when number of
30          dimension zones is not a power of two
31        - made round robin use a counter for each region instead of each
32          key
33    
34      * SFZ format engine:
35        - Initial implementation (not usable yet)
36        - added support for v2 multiple stage envelope generators
37        - added a fine-tuned v1 envelope generator instead of using the
38          one from the gig engine
39        - fixed memory leak and memory handling errors
40        - added support for trigger=first, trigger=legato and sw_previous
41        - allow non-numerical key values ("C#4" for example)
42        - "key" opcode now sets pitch_keycenter too
43        - fixed error when unloading instrument with same sample used by
44          multiple regions
45        - added some opcode aliases, like loopmode for loop_mode, to be
46          more compatible
47        - added support for trigger=release and rt_decay
48        - added support for off_mode=normal
49        - added support for random, seq_position, seq_length and volume
50        - added v1 LFO opcodes to parser (no support in engine yet)
51        - added support for amp_veltrack and amp_velcurve_N
52        - fine-tuned the default velocity curve
53        - added support for transpose
54        - fixed crash when using sw_down/up
55        - improved logic for sw_lokey/hikey/up/down/last
56        - added more v1 aliases to parser
57        - reduced memory usage for sfz data
58        - RT-safeness: avoid malloc in audio thread
59        - fixed a bug that could cause voice stealing to fail
60        - optimized sample lookup
61        - improved support for exclusive groups (group, off_by and
62          off_mode)
63        - added support for controller triggered regions (on_locc/on_hicc)
64        - added support for loop_mode=one_shot
65        - fixed playback of 16 bit wav files on big endian CPUs
66        - added support for Ogg Vorbis sample files
67    
68      * SoundFont format engine:
69        - Initial implementation (not usable yet)
70        - RT-safeness: avoid malloc in audio thread
71        - fixed a bug that could cause voice stealing to fail
72    
73      * Host plugins:
74        - AU bugfix: failed to destroy its audio/MIDI devices
75        - Listen to all interfaces on Mac OS X (INADDR_ANY)
76        - VST bugfix: If the host called resume() before and after
77          changing sample rate or block size, the number of channels was
78          incorrectly set to two. This caused silence in Cubase 5.
79    
80      * MIDI driver:
81        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
82          the ALSA sequencer client name
83

113          <effect-chain> <effect-instance>"
114    
115      * Bug fixes:
116        - Fixed crash which may occur when MIDI key + transpose is out of range
117        - minor valgrind fixes
118        - fixed crash which occured when changing an already deployed sampler
119          channel to a different engine type
120        - fixed crash when deleting a sampler channel or changing engine
121          type while an instrument load was in progress
122    
123    Version 1.0.0 (31 July 2009)
124    
125      * packaging changes:
126        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
127          causing e.g. the libgig test to fail when
128          "./configure --disable-jack-driver" was used
129          (patch by Alexis Ballier)
130        - fixed compilation with gcc 4.3
131        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
132        - fixed configure so it detects x86_64 (#107)
133        - fixes for building with newer MinGW versions
134        - fix for building with bison 2.4 (#111)
135        - fixed building with libgig installed in a non-standard directory
136        - minor fix in configure for mmsystem.h detection on MinGW
137        - Windows: look for editor plugins and Fantasia using base
138          directory of liblinuxsampler dll (look in the same directory and one
139          directory above)
140        - configure script fix: removed unconditional use of SSE
141        - fixed building with sqlite installed in a non-standard directory
142        - when cross-compiling, don't try to create instruments.db
143        - fix for new mingw-w64 version, which has usleep
144    
145      * general changes:
146        - bugfix: on some POSIX systems instrument editor plugins refused to
147          load as we used a non-portable Linux specific struct field
148          (fixes bug #70, patch by Ronald Baljeu)
149        - fixed endless loop which occured when loading an instrument editor
150          plugin DLL on Windows systems failed
151        - fixed memory leaks that occurred when liblinuxsampler was unloaded
152        - optimized the SynchronizedConfig class so it doesn't wait
153          unnecessarily long after an update
154        - added support for notifying instrument editors on note-on / note-off
155          events (e.g. to highlight the pressed keys on the virtual keyboard
156          of gigedit)
157        - added support for triggering notes by instrument editors (see above)
158        - be verbose on DLL load errors (on Linux)
159        - fixed di-harmonic triangle LFO implementation (this LFO implementation
160          is only used by very few systems, most pick the int math
161          implementation, which is usually faster)
162        - fixes for audio drivers with varying buffer sizes
163        - experimental support for running LinuxSampler as a DSSI, LV2 and
164          VST plugin
165        - notification events for stream/voice count statistics are now sent
166          only when there are actual changes
167        - added memory ordering constraints to improve stability on
168          multi-core and multi-cpu systems
169        - maximum voices and disk streams can now be altered at runtime
170        - fixed CPU feature detection on x86_64 (maybe fixes #108)
171        - automatic stacktrace mechanism is now turned off by default and can
172          be switched on by command line option "--stacktrace" (the automatic
173          stacktrace mechanism seems to be broken on most systems at the moment)
174        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
175          a pointer to the launched InstrumentEditor object
176        - added optional 3rd party user data parameter for following
177          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
178          InstrumentEditor::Launch(),
179          InstrumentManager::LaunchInstrumentEditor()
180        - theoretical fix: made SynchronizedConfig follow C++0x memory
181          model more strictly
182        - fixes for using large audio device buffers
183        - Windows: add the installation directory to the DLL search path
184          when loading an editor plugin (solves problems with VST and
185          gigedit on systems with other GTK versions installed)
186    
187      * audio driver:
188        - removed the nonsense audio channel constraint (which was hard coded to
189          max. 100 audio channels) for most audio drivers
190        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
191          opposed to the LSCP specs
192        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
193          reflected the wrong value
194        - fixed a memory management bug in ASIO driver
195        - Makefile fix: JACK_CFLAGS wasn't used
196        - JACK: use jack_client_open instead of the deprecated
197          jack_client_new
198        - added (experimental) CoreAudio driver
199        - applied old fixes to the ASIO driver that were included in the
200          previous binary release but accidentally never committed to CVS
201          (fixes #117)
202        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
203          win64)
204        - VST: added support for sample rate and buffer size changes
205        - VST: close editor (Fantasia) when the VST is removed
206        - VST: avoid opening Fantasia more than once for each VST instance
207        - VST: export main function as "main" on Linux too (fix for
208          energyXT)
209        - VST: changed number of output channels from one stereo to 16
210          stereo
211        - added channel routing, fxsends and midi maps to the settings
212          stored in the plugin state
213        - performance optimization of AudioChannel::MixTo() and
214          AudioChannel::CopyTo() methods using GCC vector exensions
215          (if available)
216        - ASIO fixes: avoid initializing the device twice, avoid throwing
217          exception when getting parameters from a disconnected device
218    
219      * MIDI driver:
220        - added JACK MIDI driver
221        - dispatch bank select as ordinary CC as well, the user might seriously
222          want to (mis)use it for some purpose ("fixed" in all current MIDI
223          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
224        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
225          CoreMidi or AU
226        - fixed mingw-w64 compilation error in MME driver
227        - made program change handling in MIDI thread real-time safe by
228          moving the logic to a non-RT thread
229        - fixed minor memory leak in ALSA driver
230    
231      * instruments database:
232        - avoid time consuming samples scanning when adding instruments
233          to the instruments database
234        - added support for handling lost files in the instruments database
235        - Implemented option for adding instruments in separate directories
236          in the instruments database
237          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
238        - work-around for missing fnmatch function on Windows to make
239          instrument database compilable
240        - added instrument database support on Windows
241          works with both standalone mode and VST plugin.
242          the instruments DB file is located in
243          %USERPROFILE%\.linuxsampler\instruments.db which allows different
244          databases for each windows user
245          if no DB is present it automatically creates the .linuxsampler subdir
246          and then creates an empty DB
247        - fixed recursive import, which was broken on Windows
248    
249      * Gigasampler format engine:
250        - fixed a memory leak that could happen when a channel was deleted
251          while notes were playing
252        - made it possible to load an instrument even if the audio thread
253          isn't running
254        - added partial support for the "Controller Triggered" MIDI rule,
255          enough for piano gigs with pedal noise samples
256        - minor fix: only mark FX sends as being modified if really the
257          respective FX send MIDI controller was used
258        - added support for GM global device volume SysEx message
259          (can be selected at compile time to either apply globally to the
260          whole sampler [default] or only to the sampler channels that are
261          connected to the respective MIDI input port the SysEx message arrived
262          on)
263        - bugfix: notes triggered at position 0 in the audio buffer were
264          sometimes wrongly killed in the same buffer, causing no sound to
265          be played
266        - added support for chromatic / drumkit mode Roland GS Sysex message
267          which is usally used to switch a part between chromatic sounds and
268          drumkit sounds (as opposed to their common default setting of MIDI
269          part 10 being a drumkit part and all other ones chromatic parts), in
270          LS however one can switch between the first 16 MIDI instrument maps
271          defined for the sampler
272        - made it possible to create multiple sample channels even if the
273          audio thread isn't running
274        - fixed crash when removing channel with active voices (#116)
275        - bugfix: on sample reference changes (instrument editor), only
276          un-cache the respective sample if it's really not used by any
277          sampler engine anymore
278        - re-cache samples in case they were changed by an instrument editor,
279          e.g. when a sample was added while playing (#82)
280        - fixed hanging notes which occured when note-off event had the exact
281          same time stamp as the voice's note-on event and occured both in the
282          same audio fragment cycle (fixes bug #112)
283        - added support for the "fine tune" and "pitch bend range"
284          instrument-level gig parameters
285        - fixed minor artifacts in pitch bend handling
286        - added support for GS Reset SysEx message
287        - allow gig files to use unlimited downward pitch shifting
288        - added a limit check for upward pitch shifting
289        - bugfix: sometimes, when playing a note twice fast, the second
290          note was silent
291        - fixed crash happening when a pitch bend event arrived at the
292          same time a new instrument was loading
293    
294      * LSCP server:
295        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
296          react on MIDI data arriving on certain sampler channels (so far only
297          Note-On and Note-Off events are sent via this LSCP event)
298        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
299          react on MIDI data arriving on certain MIDI input devices (so far only
300          Note-On and Note-Off events are sent via this LSCP event)
301        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
302          SET DB_INSTRUMENT FILE_PATH
303        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
304          frontends to send MIDI messages to specific sampler channel
305        - added two additional fields to GET FILE INSTRUMENT INFO command -
306          KEY_BINDINGS and KEYSWITCH_BINDINGS
307        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
308          was incorrect
309        - Optimized the retrieval of the MIDI instrument mappings
310        - added new LSCP command "SET VOICES" to globally alter the maximum
311          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
312          be triggered respectively
313        - added new LSCP command "SET STREAMS" to globally alter the maximum
314          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
315          which will be triggered respectively
316        - bugfix: retry if "select" returns EINTR (this fixes a crash when
317          a gigedit file dialog is opened)
318        - close all connections when LSCPServer is deleted
319        - hard close of all sockets on exit
320        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
321          driver
322    
323      * Bug fixes:
324        - fixed a crash which occurs when removing a sampler channel waiting
325          to start instrument loading after another channel
326        - fixed a crash which occurs when removing a sampler channel with
327          instrument loading in progress (bug #113)
328        - fixed termination caused by uncaught exception when adding MIDI
329          instrument with PERSISTENT load mode
330        - fixed possible iterator invalidations when resetting the sampler
331        - fixed memory leaks when issuing the following LSCP commands:
332          GET AUDIO_OUTPUT_DRIVER INFO
333          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
334          GET MIDI_INPUT_DRIVER INFO
335          GET MIDI_INPUT_DRIVER_PARAMETER INFO
336        - fixed possible compilation error when sqlite is not present
337        - fixed orphaned pointers when setting maximum voices limit (bug #118)
338        - fixed crash when changing the audio output device of a sampler
339          channel with loaded instrument and start playing notes
340        - fixed endless loop in Engine::SuspendAll() (bug #120)
341        - fixed a low-level atomic load function that was broken on 64-bit
342          PowerPC, which probably could cause crashes on that platform
343        - fixed a memory management error which could cause a crash when a
344          plugin was unloaded
345        - bugfix: two private structs had the same name, which could cause
346          problems if the linker chose the wrong constructor
347        - fixed low-level ConditionServer usage bug that caused lockups on
348          Windows
349    
350    
351    Version 0.5.1 (6 December 2007)
352    
353      * packaging changes:
354        - added autoconf checks for pthread library
355        - added autoconf check for pthread bug found on certain NPTL-enabled
356          glibc versions (see Gentoo bug report #194076)
357        - added autoconf checks for MS Windows
358    
359      * general changes:
360        - bugfix: the thread used by an editor plugin didn't die when the
361          editor closed
362        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
363          out all the space. operator--() did not apply size_mask after
364          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
365          order to avoid problems with the _NonVolatileReader functions.
366        - bugfix: Stream.h: added a missing divide by BytesPerSample in
367          GetWriteSpace(). Since this function is currently only used in
368          the stream's qsort() compare function, it didn't trigger any
369          bugs.
370        - Resampler.h, Synthesizer.h: cubic interpolation now works in
371          24bit mode too. Faster method to read 24bit words on little
372          endian machines (x86): replaced 3 byte reads + shifts with a 1
373          unaligned 32bit read and shift
374        - experimental support for MS Windows (MIDI input via MME, AUDIO
375          output via ASIO)
376        - made handling of SIGINT signal (Ctrl-C) a bit more robust
377        - support for monitoring the total number of active disk streams
378          (new LSCP commands: GET TOTAL_STREAM_COUNT,
379          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
380    
381      * AUDIO driver:
382        - added Windows ASIO low latency audio driver
383    
384      * MIDI driver:
385        - added MME Windows MIDI driver
386    
387      * LSCP server:
388        - added support for Windows style path / filenames, however with
389          forward slash path separators instead of backslash
390          (i.e. "C:/foo/bar.gig")
391        - allow naughty liblscp to send non-string device parameters within
392          apostrophes as well
393        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
394          "LIST FILE INSTRUMENTS <file>" and
395          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
396          about an arbitrary instrument file on the system where the sampler is
397          running on
398    
399    Version 0.5.0 (15 October 2007)
400    
401      * packaging changes:
402        - config.h is not going to be installed along with liblinuxsampler's
403          API header files anymore
404        - only the API relevant header (and source) files will be exported to
405          the Doxygen API documentation (explicitly listed in Doxyfile.in)
406        - added completely new XCode project files for Mac OSX which is now
407          capable to execute our autoconf environment, thus no need anymore
408          to maintain the compile time configuration file (osx/version.h) for
409          OSX manually (patch by Toshi Nagata)
410        - fixed buggy boolean --enable-foo / --disable-foo configure script
411          parameters
412        - global.h now only covers global definitions that are needed for the
413          C++ API header files, all implementation internal global definitions
414          are now in global_private.h
415        - atomic.h is not exposed to the C++ API anymore
416        - no need to include config.h anymore for using LS's API header files
417        - fixed warnings in API doc generation
418    
419      * general changes:
420        - replaced the old, confusing MIDI program change mechanism by a
421          flexible MIDI instrument mapper which allows to map arbitrary
422          (MIDI bank, MIDI program) pairs with arbitrary
423          (engine type, instrument file, file index) triplets which will be
424          loaded on the respective channel when such MIDI program change
425          messages arrive, beside that, each entry allows to define a life-time
426          strategy for the instrument, so the user can define whether the
427          instrument should i.e. be permanently loaded (to be able to switch
428          quickly among sounds) or i.e. loaded just on demand when the
429          respective program change arrives (to safe RAM space), as well as a
430          global volume factor for each entry, so the user can adjust the volume
431          dynamic of his mapped instrument collection without having to modify
432          the instrument files, also one can manage arbitrary amount of such
433          MIDI instrument maps and assign each sampler channel individually
434          a certain map, so that i.e. separation of normal instruments and
435          drumkits is possible
436        - new notification events for tracking changes to audio/MIDI devices,
437          MIDI instrument maps, MIDI instruments, FX sends, global volume.
438        - sampler was limited to load max. 200 instruments in the background
439          due to a constant size RingBuffer FIFO which is now replaced by a
440          dynamic (unlimited) size std::list FIFO
441        - added FX sends, these allow to route audio signals to arbitrary audio
442          output channels for being processed by external effect processors
443          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
444          controllers
445        - global (sampler wide) volume can now be controlled at runtime
446        - Implemented new, improved notification system
447        - fixed compilation errors regarding OSX
448          (patch by Toshi Nagata)
449        - implemented instruments database
450        - added support for escape sequences to the instruments database
451        - added highly experimental support for on-the-fly instrument editing
452          within the sampler's process (by using instrument editor plugins),
453          you'll notice the new "Registered instrument editors:" message on
454          startup, added a new LSCP command:
455          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
456          to spawn a matching instrument editor for the instrument on the
457          given sampler channel, the plugin path can be overridden at compile
458          time with ./configure --enable-plugin-dir=/some/dir
459        - added experimental code for synchronizing instrument editors hosted
460          in the sampler's process to safely edit instruments while playing
461          without a crash (hopefully) by either suspending single regions
462          wherever possible or if unavoidable whole engine(s)
463        - fixed several issues in fundamental "Thread" class: set scheduling
464          policy and priority on thread level, set a minimum stack size for
465          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
466          threads simply inherited properties of starting thread instead of
467          setting their own policy and priority
468        - minor fix in our automatic stack trace mechanism on crashes, the
469          main process did not wait for the stack trace process to finish
470          its output
471        - fixed some minor memory leaks
472        - reenabled assembly features support, at the moment only for
473          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
474        - minor assembly fix in x86 features detection (don't use the PIC
475          register, to avoid relocations in the text segment at runtime)
476        - POSIX callback functions of Thread.h are hidden
477    
478      * MIDI driver:
479        - dispatch bank select (MSB and LSB) messages
480    
481      * audio driver:
482        - the ALSA audio output driver parameters now reflect the correct
483          parameter value ranges for the respective selected sound card
484          (patch by Till Wimmer, a bit fixed and extended)
485    
486      * Gigasampler format engine:
487        - if a filter is used and EG2 finishes before EG1, let the voice
488          die when EG2 has finished (this fixes a problem with clicks and
489          voice starvation for some gigs)
490        - playback is no longer disabled during instrument loading
491        - all notes playing on a channel that changes its instrument keep
492          playing with the old instrument until they get a note off
493          command
494        - EG fix: a release value of zero could cause noises or crash
495        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
496        - EG fine tuning: when attack is zero the EG starts at a level
497          above max sustain level, which means that there is a decay phase
498          even if sustain is 100%
499        - more EG fixes: the level could sometimes go below zero and cause
500          noises or crashes
501        - minor fix of EGDecay (patch by Toshi Nagata)
502        - fixed compiler error when --enable-override-filter-type was
503          supplied to the configure script (fixes #46)
504        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
505          instead of a fix value
506        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
507          127 (solo mode) only kill voices if the respective mode really
508          changed
509    
510      * LSCP server:
511        - fixed compile time error for old Bison versions
512          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
513        - parser now supports extended ASCII character set
514          (up to ASCII code 255, i.e. includes now umlauts and accents)
515        - filename arguments in LSCP commands now allow to use escape
516          sequences, that is directly literal as one of: \', \", \\, \n, \r,
517          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
518          code value like \xf2) (fixes bug #24)
519        - the following LSCP commands now also support escape sequences for at
520          least one of their text-based parameters (i.e. name, description):
521          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
522          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
523          "SET DB_INSTRUMENT_DIRECTORY NAME",
524          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
525          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
526          "FIND DB_INSTRUMENT_DIRECTORIES"
527        - returns verbose syntax errors (line and column where syntax error
528          occured, the unexpected character and the actually expected, possible
529          character(s), the latter only if less than 5 possibilities)
530        - made sure that LSCP syntax is not affected by gigedit locale
531          settings
532        - bugfix regarding strings parameter lists: all comma separated lists
533          of strings were treated as being one string containing commas
534          (fixes #57)
535    
536      * Bug fixes:
537        - fixed crash occurring on certain LSCP scripts (Bug 39)
538        - another thread safety fix for lscp "load engine" and "set
539          channel audio output device"
540        - fixed a crash which occurs when reassigning the same engine
541          on a sampler channel with connected MIDI device
542        - fixed a crash which occurs when changing the number of ports of a MIDI
543          device connected to a sampler channel to number less then or equal
544          to the index of the port to which the sampler channel is connected.
545        - The previous bindings were not been disconnected when altering
546          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
547          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
548        - The active stream/voice count statistic was incorrect.
549        - notification events were not been sent for some sampler
550          channel changes
551        - added default min and max values to restrict the number of allowed
552          audio output channels and MIDI input ports
553        - the connection to the PCM interface is now closed when destroying
554          an audio output device
555        - files with slash in their path or filename could not be loaded
556    
557      * test cases:
558        - updated and fixed (haven't been touched in a while)
559    
560    Version 0.4.0 (24 November 2006)
561    
562      * packaging changes:
563        - changed deprecated copyright attribute to license; added ldconfig
564          to post-(un)install steps; added devel package for liblinuxsampler;
565          to linuxsampler.spec (RPM)
566        - install necessary development header files for allowing 3rd party
567          applications to link against liblinuxsampler
568        - liblinuxsampler's API documentation can be generated with 'make docs'
569          (Doxygen required)
570        - added benchmark to automatically detect the best triangle LFO
571          implementation (currently either an integer math solution or a
572          di-harmonic approximation), automatic detection can be overriden
573          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
574          configure script argument though (mandatory for cross-compilation)
575        - do not automatically pick optimized gcc flags if the user already
576          provided some on his own (as CXXFLAGS)
577        - added compile time option to disable processing of All-Notes-Off MIDI
578          messages
579        - added compile time options to allow disabling the various audio and
580          MIDI drivers
581        - fixed automatic GCC CPU switch detection on PPC
582          (patch by Ebrahim Mayat)
583    
584      * Gigasampler format engine:
585        - extensive synthesis optimization
586          (reimplementation of EGs and LFO(s), removed synthesis parameter
587          prerendering and the synthesis parameter matrix in general, splitting
588          each audio fragment into subfragments now where each subfragment uses
589          constant pitch and filter coefficients. The volume coefficient is
590          linearly interpolated inside a subfragment, unless
591          --disable-interpolate-volume is set.)
592        - fine tuning of the EG modulation parameters
593        - improved filter cutoff calculation by adding support for the
594          following gig parameters: Cutoff freq (used when no cutoff
595          controller is defined), Control invert, Minimum cutoff, Velocity
596          curve and Velocity range. The keyboard tracking now scales
597          cutoff frequency instead of resonance.
598        - added support for gig parameter Resonance.
599        - fixed bug in sysex handling (patch by Juan Linietsky)
600        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
601          which can be overridden with --enable-global-attenuation
602        - EG fixes: made the length of "attack hold" stage more
603          accurate. Release stage can now start before attack stage
604          ends. Cancel release didn't work when sustain was zero. Attack
605          time now has a minimal value to prevent clicks.
606        - fixed pitch changes larger than one octave
607        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
608        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
609          all modes can be altered via standard GM messages, that is CC5 for
610          altering portamento time, CC65 for enabling / disabling portamento
611          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
612        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
613          parameter) and crossfade
614        - added support for the "attenuation controller threshold" gig
615          parameter
616        - added smoothing of volume changes caused by control change
617          messages
618        - sample loop parameters are now taken from the DimensionRegion
619          instead of the wave chunk
620        - fixed keyswitching for v3 gigs with a number of keyswitch splits
621          not equal to a power of two
622        - reimplementation of the filter algorithm. The new filter is more
623          accurate and supports all gig filter types, including bandreject
624          and lowpass turbo.
625        - real support for 24 bit samples - samples are not truncated to
626          16 bits anymore
627        - support for aftertouch (channel pressure, not polyphonic
628          aftertouch)
629        - LFO1 behaviour fixed (dampening from max volume instead of
630          amplifying from 0)
631    
632      * LSCP server:
633        - fixed application exit on broken pipe error (fixes bug #20)
634        - fixed the notification messages delay due to lack of
635          network activity (fixes bug #26)
636        - fixed parser bug which occured on space(s) within device parameters
637          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
638    
639      * audio driver:
640        - added aRts audio output driver (by no means RT safe)
641    
642      * MIDI driver:
643        - fixed legacy sysex code which caused dispatching of MIDI SysEx
644          messages several times instead of once
645        - API extension for MIDI drivers which already supply exact time stamps
646          for events (i.e. for offline rendering based MIDI drivers)
647        - added checks for bad MIDI data
648    
649      * linuxsampler application:
650        - show available sampler engine types on startup
651    
652      * general changes:
653        - support for muting sampler channels and solo mode of the same, two new
654          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
655          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
656          introduced for this, the behavior is the same like on a mixer console
657          (patch by Grigor Iliev, a bit adjusted). Also added configure option
658          --enable-process-muted-channels which can be used to enable the
659          processing of muted channels.
660        - support for sostenuto pedal
661        - support for monitoring the total number of active voices
662          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
663          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
664        - fixed some memory management errors
665        - fixed some concurrency problems that could lead to crashes when
666          LSCP commands were executed
667        - fixed crash when instrument loading failed previously on the same
668          sampler channel (fixes bug #36)
669    
670    Version 0.3.3 (15 July 2005)
671    
672      * packaging changes:
673        - fixed compilation with gcc 4.0
674    
675      * Gigasampler format engine:
676        - LFO preprocessing was performed even though the respective LFO was
677          disabled by the instrument patch (minor efficiency fix)
678        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
679          for volume ramp downs in the same fragment (needed for current voice
680          stealing implementation) then simply inform the user with a warning
681          about possible click sounds and reduce the volume ramp down
682          appropriately instead of cancelling the audio device connection
683    
684    Version 0.3.2 (24 June 2005)
685    
686      * packaging changes:
687      - updated autotools build files to compile on OS X      - updated autotools build files to compile on OS X
688        (conditional compilation of CoreMIDI and MidiShare drivers)        (conditional compilation of CoreMIDI and MidiShare drivers)
689      - hand-crafted assembly optimization code can be disabled with      - hand-crafted assembly optimization code can be disabled with

707        this case was followed by a "killed voice survived" error message)        this case was followed by a "killed voice survived" error message)
708        - fixed minor issue with null/silence samples
709          (those stole voices even though they don't need a voice at all which
710          resulted in "voice stealing didn't work out" messages)
711        - don't reset volume, pan, pitch and MIDI controller values on
712          instrument or audio output device change
713    
714    * LSCP server:    * LSCP server:
715      - fixed some crashes (patch by Grigor Iliev, fixes #19)      - fixed some crashes (patch by Grigor Iliev, fixes #19)
