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    
26      * Gigasampler format engine:
27        - implemented the "round robin keyboard" dimension
28        - fixed round robin and random dimensions for cases when number of
29          dimension zones is not a power of two
30        - made round robin use a counter for each region instead of each
31          key
32    
33      * SFZ format engine:
34        - Initial implementation (not usable yet)
35        - added support for v2 multiple stage envelope generators
36        - added a fine-tuned v1 envelope generator instead of using the
37          one from the gig engine
38        - fixed memory leak and memory handling errors
39        - added support for trigger=first, trigger=legato and sw_previous
40        - allow non-numerical key values ("C#4" for example)
41        - "key" opcode now sets pitch_keycenter too
42        - fixed error when unloading instrument with same sample used by
43          multiple regions
44        - added some opcode aliases, like loopmode for loop_mode, to be
45          more compatible
46        - added support for trigger=release and rt_decay
47        - added support for off_mode=normal
48        - added support for random, seq_position, seq_length and volume
49        - added v1 LFO opcodes to parser (no support in engine yet)
50        - added support for amp_veltrack and amp_velcurve_N
51        - fine-tuned the default velocity curve
52        - added support for transpose
53        - fixed crash when using sw_down/up
54        - improved logic for sw_lokey/hikey/up/down/last
55        - added more v1 aliases to parser
56        - reduced memory usage for sfz data
57        - RT-safeness: avoid malloc in audio thread
58        - fixed a bug that could cause voice stealing to fail
59        - optimized sample lookup
60        - improved support for exclusive groups (group, off_by and
61          off_mode)
62        - added support for controller triggered regions (on_locc/on_hicc)
63        - added support for loop_mode=one_shot
64        - fixed playback of 16 bit wav files on big endian CPUs
65        - added support for Ogg Vorbis sample files
66    
67      * SoundFont format engine:
68        - Initial implementation (not usable yet)
69        - RT-safeness: avoid malloc in audio thread
70        - fixed a bug that could cause voice stealing to fail
71    
72      * Host plugins:
73        - AU bugfix: failed to destroy its audio/MIDI devices
74        - Listen to all interfaces on Mac OS X (INADDR_ANY)
75        - VST bugfix: If the host called resume() before and after
76          changing sample rate or block size, the number of channels was
77          incorrectly set to two. This caused silence in Cubase 5.
78    
79      * MIDI driver:
80        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
81          the ALSA sequencer client name
82    
83      * LSCP server:
84        - added support for sending MIDI CC messages via LSCP command
85          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
86    
87      * Bug fixes:
88        - Fixed crash which may occur when MIDI key + transpose is out of range
89        - minor valgrind fixes
90        - fixed crash which occured when changing an already deployed sampler
91          channel to a different engine type
92    
93    Version 1.0.0 (31 July 2009)
94    
95      * packaging changes:
96        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
97          causing e.g. the libgig test to fail when
98          "./configure --disable-jack-driver" was used
99          (patch by Alexis Ballier)
100        - fixed compilation with gcc 4.3
101        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
102        - fixed configure so it detects x86_64 (#107)
103        - fixes for building with newer MinGW versions
104        - fix for building with bison 2.4 (#111)
105        - fixed building with libgig installed in a non-standard directory
106        - minor fix in configure for mmsystem.h detection on MinGW
107        - Windows: look for editor plugins and Fantasia using base
108          directory of liblinuxsampler dll (look in the same directory and one
109          directory above)
110        - configure script fix: removed unconditional use of SSE
111        - fixed building with sqlite installed in a non-standard directory
112        - when cross-compiling, don't try to create instruments.db
113        - fix for new mingw-w64 version, which has usleep
114    
115      * general changes:
116        - bugfix: on some POSIX systems instrument editor plugins refused to
117          load as we used a non-portable Linux specific struct field
118          (fixes bug #70, patch by Ronald Baljeu)
119        - fixed endless loop which occured when loading an instrument editor
120          plugin DLL on Windows systems failed
121        - fixed memory leaks that occurred when liblinuxsampler was unloaded
122        - optimized the SynchronizedConfig class so it doesn't wait
123          unnecessarily long after an update
124        - added support for notifying instrument editors on note-on / note-off
125          events (e.g. to highlight the pressed keys on the virtual keyboard
126          of gigedit)
127        - added support for triggering notes by instrument editors (see above)
128        - be verbose on DLL load errors (on Linux)
129        - fixed di-harmonic triangle LFO implementation (this LFO implementation
130          is only used by very few systems, most pick the int math
131          implementation, which is usually faster)
132        - fixes for audio drivers with varying buffer sizes
133        - experimental support for running LinuxSampler as a DSSI, LV2 and
134          VST plugin
135        - notification events for stream/voice count statistics are now sent
136          only when there are actual changes
137        - added memory ordering constraints to improve stability on
138          multi-core and multi-cpu systems
139        - maximum voices and disk streams can now be altered at runtime
140        - fixed CPU feature detection on x86_64 (maybe fixes #108)
141        - automatic stacktrace mechanism is now turned off by default and can
142          be switched on by command line option "--stacktrace" (the automatic
143          stacktrace mechanism seems to be broken on most systems at the moment)
144        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
145          a pointer to the launched InstrumentEditor object
146        - added optional 3rd party user data parameter for following
147          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
148          InstrumentEditor::Launch(),
149          InstrumentManager::LaunchInstrumentEditor()
150        - theoretical fix: made SynchronizedConfig follow C++0x memory
151          model more strictly
152        - fixes for using large audio device buffers
153        - Windows: add the installation directory to the DLL search path
154          when loading an editor plugin (solves problems with VST and
155          gigedit on systems with other GTK versions installed)
156    
157      * audio driver:
158        - removed the nonsense audio channel constraint (which was hard coded to
159          max. 100 audio channels) for most audio drivers
160        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
161          opposed to the LSCP specs
162        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
163          reflected the wrong value
164        - fixed a memory management bug in ASIO driver
165        - Makefile fix: JACK_CFLAGS wasn't used
166        - JACK: use jack_client_open instead of the deprecated
167          jack_client_new
168        - added (experimental) CoreAudio driver
169        - applied old fixes to the ASIO driver that were included in the
170          previous binary release but accidentally never committed to CVS
171          (fixes #117)
172        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
173          win64)
174        - VST: added support for sample rate and buffer size changes
175        - VST: close editor (Fantasia) when the VST is removed
176        - VST: avoid opening Fantasia more than once for each VST instance
177        - VST: export main function as "main" on Linux too (fix for
178          energyXT)
179        - VST: changed number of output channels from one stereo to 16
180          stereo
181        - added channel routing, fxsends and midi maps to the settings
182          stored in the plugin state
183        - performance optimization of AudioChannel::MixTo() and
184          AudioChannel::CopyTo() methods using GCC vector exensions
185          (if available)
186        - ASIO fixes: avoid initializing the device twice, avoid throwing
187          exception when getting parameters from a disconnected device
188    
189      * MIDI driver:
190        - added JACK MIDI driver
191        - dispatch bank select as ordinary CC as well, the user might seriously
192          want to (mis)use it for some purpose ("fixed" in all current MIDI
193          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
194        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
195          CoreMidi or AU
196        - fixed mingw-w64 compilation error in MME driver
197        - made program change handling in MIDI thread real-time safe by
198          moving the logic to a non-RT thread
199        - fixed minor memory leak in ALSA driver
200    
201      * instruments database:
202        - avoid time consuming samples scanning when adding instruments
203          to the instruments database
204        - added support for handling lost files in the instruments database
205        - Implemented option for adding instruments in separate directories
206          in the instruments database
207          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
208        - work-around for missing fnmatch function on Windows to make
209          instrument database compilable
210        - added instrument database support on Windows
211          works with both standalone mode and VST plugin.
212          the instruments DB file is located in
213          %USERPROFILE%\.linuxsampler\instruments.db which allows different
214          databases for each windows user
215          if no DB is present it automatically creates the .linuxsampler subdir
216          and then creates an empty DB
217        - fixed recursive import, which was broken on Windows
218    
219      * Gigasampler format engine:
220        - fixed a memory leak that could happen when a channel was deleted
221          while notes were playing
222        - made it possible to load an instrument even if the audio thread
223          isn't running
224        - added partial support for the "Controller Triggered" MIDI rule,
225          enough for piano gigs with pedal noise samples
226        - minor fix: only mark FX sends as being modified if really the
227          respective FX send MIDI controller was used
228        - added support for GM global device volume SysEx message
229          (can be selected at compile time to either apply globally to the
230          whole sampler [default] or only to the sampler channels that are
231          connected to the respective MIDI input port the SysEx message arrived
232          on)
233        - bugfix: notes triggered at position 0 in the audio buffer were
234          sometimes wrongly killed in the same buffer, causing no sound to
235          be played
236        - added support for chromatic / drumkit mode Roland GS Sysex message
237          which is usally used to switch a part between chromatic sounds and
238          drumkit sounds (as opposed to their common default setting of MIDI
239          part 10 being a drumkit part and all other ones chromatic parts), in
240          LS however one can switch between the first 16 MIDI instrument maps
241          defined for the sampler
242        - made it possible to create multiple sample channels even if the
243          audio thread isn't running
244        - fixed crash when removing channel with active voices (#116)
245        - bugfix: on sample reference changes (instrument editor), only
246          un-cache the respective sample if it's really not used by any
247          sampler engine anymore
248        - re-cache samples in case they were changed by an instrument editor,
249          e.g. when a sample was added while playing (#82)
250        - fixed hanging notes which occured when note-off event had the exact
251          same time stamp as the voice's note-on event and occured both in the
252          same audio fragment cycle (fixes bug #112)
253        - added support for the "fine tune" and "pitch bend range"
254          instrument-level gig parameters
255        - fixed minor artifacts in pitch bend handling
256        - added support for GS Reset SysEx message
257        - allow gig files to use unlimited downward pitch shifting
258        - added a limit check for upward pitch shifting
259        - bugfix: sometimes, when playing a note twice fast, the second
260          note was silent
261        - fixed crash happening when a pitch bend event arrived at the
262          same time a new instrument was loading
263    
264      * LSCP server:
265        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
266          react on MIDI data arriving on certain sampler channels (so far only
267          Note-On and Note-Off events are sent via this LSCP event)
268        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
269          react on MIDI data arriving on certain MIDI input devices (so far only
270          Note-On and Note-Off events are sent via this LSCP event)
271        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
272          SET DB_INSTRUMENT FILE_PATH
273        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
274          frontends to send MIDI messages to specific sampler channel
275        - added two additional fields to GET FILE INSTRUMENT INFO command -
276          KEY_BINDINGS and KEYSWITCH_BINDINGS
277        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
278          was incorrect
279        - Optimized the retrieval of the MIDI instrument mappings
280        - added new LSCP command "SET VOICES" to globally alter the maximum
281          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
282          be triggered respectively
283        - added new LSCP command "SET STREAMS" to globally alter the maximum
284          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
285          which will be triggered respectively
286        - bugfix: retry if "select" returns EINTR (this fixes a crash when
287          a gigedit file dialog is opened)
288        - close all connections when LSCPServer is deleted
289        - hard close of all sockets on exit
290        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
291          driver
292    
293      * Bug fixes:
294        - fixed a crash which occurs when removing a sampler channel waiting
295          to start instrument loading after another channel
296        - fixed a crash which occurs when removing a sampler channel with
297          instrument loading in progress (bug #113)
298        - fixed termination caused by uncaught exception when adding MIDI
299          instrument with PERSISTENT load mode
300        - fixed possible iterator invalidations when resetting the sampler
301        - fixed memory leaks when issuing the following LSCP commands:
302          GET AUDIO_OUTPUT_DRIVER INFO
303          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
304          GET MIDI_INPUT_DRIVER INFO
305          GET MIDI_INPUT_DRIVER_PARAMETER INFO
306        - fixed possible compilation error when sqlite is not present
307        - fixed orphaned pointers when setting maximum voices limit (bug #118)
308        - fixed crash when changing the audio output device of a sampler
309          channel with loaded instrument and start playing notes
310        - fixed endless loop in Engine::SuspendAll() (bug #120)
311        - fixed a low-level atomic load function that was broken on 64-bit
312          PowerPC, which probably could cause crashes on that platform
313        - fixed a memory management error which could cause a crash when a
314          plugin was unloaded
315        - bugfix: two private structs had the same name, which could cause
316          problems if the linker chose the wrong constructor
317        - fixed low-level ConditionServer usage bug that caused lockups on
318          Windows
319    
320    
321    Version 0.5.1 (6 December 2007)
322    
323      * packaging changes:
324        - added autoconf checks for pthread library
325        - added autoconf check for pthread bug found on certain NPTL-enabled
326          glibc versions (see Gentoo bug report #194076)
327        - added autoconf checks for MS Windows
328    
329      * general changes:
330        - bugfix: the thread used by an editor plugin didn't die when the
331          editor closed
332        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
333          out all the space. operator--() did not apply size_mask after
334          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
335          order to avoid problems with the _NonVolatileReader functions.
336        - bugfix: Stream.h: added a missing divide by BytesPerSample in
337          GetWriteSpace(). Since this function is currently only used in
338          the stream's qsort() compare function, it didn't trigger any
339          bugs.
340        - Resampler.h, Synthesizer.h: cubic interpolation now works in
341          24bit mode too. Faster method to read 24bit words on little
342          endian machines (x86): replaced 3 byte reads + shifts with a 1
343          unaligned 32bit read and shift
344        - experimental support for MS Windows (MIDI input via MME, AUDIO
345          output via ASIO)
346        - made handling of SIGINT signal (Ctrl-C) a bit more robust
347        - support for monitoring the total number of active disk streams
348          (new LSCP commands: GET TOTAL_STREAM_COUNT,
349          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
350    
351      * AUDIO driver:
352        - added Windows ASIO low latency audio driver
353    
354      * MIDI driver:
355        - added MME Windows MIDI driver
356    
357      * LSCP server:
358        - added support for Windows style path / filenames, however with
359          forward slash path separators instead of backslash
360          (i.e. "C:/foo/bar.gig")
361        - allow naughty liblscp to send non-string device parameters within
362          apostrophes as well
363        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
364          "LIST FILE INSTRUMENTS <file>" and
365          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
366          about an arbitrary instrument file on the system where the sampler is
367          running on
368    
369    Version 0.5.0 (15 October 2007)
370    
371      * packaging changes:
372        - config.h is not going to be installed along with liblinuxsampler's
373          API header files anymore
374        - only the API relevant header (and source) files will be exported to
375          the Doxygen API documentation (explicitly listed in Doxyfile.in)
376        - added completely new XCode project files for Mac OSX which is now
377          capable to execute our autoconf environment, thus no need anymore
378          to maintain the compile time configuration file (osx/version.h) for
379          OSX manually (patch by Toshi Nagata)
380        - fixed buggy boolean --enable-foo / --disable-foo configure script
381          parameters
382        - global.h now only covers global definitions that are needed for the
383          C++ API header files, all implementation internal global definitions
384          are now in global_private.h
385        - atomic.h is not exposed to the C++ API anymore
386        - no need to include config.h anymore for using LS's API header files
387        - fixed warnings in API doc generation
388    
389      * general changes:
390        - replaced the old, confusing MIDI program change mechanism by a
391          flexible MIDI instrument mapper which allows to map arbitrary
392          (MIDI bank, MIDI program) pairs with arbitrary
393          (engine type, instrument file, file index) triplets which will be
394          loaded on the respective channel when such MIDI program change
395          messages arrive, beside that, each entry allows to define a life-time
396          strategy for the instrument, so the user can define whether the
397          instrument should i.e. be permanently loaded (to be able to switch
398          quickly among sounds) or i.e. loaded just on demand when the
399          respective program change arrives (to safe RAM space), as well as a
400          global volume factor for each entry, so the user can adjust the volume
401          dynamic of his mapped instrument collection without having to modify
402          the instrument files, also one can manage arbitrary amount of such
403          MIDI instrument maps and assign each sampler channel individually
404          a certain map, so that i.e. separation of normal instruments and
405          drumkits is possible
406        - new notification events for tracking changes to audio/MIDI devices,
407          MIDI instrument maps, MIDI instruments, FX sends, global volume.
408        - sampler was limited to load max. 200 instruments in the background
409          due to a constant size RingBuffer FIFO which is now replaced by a
410          dynamic (unlimited) size std::list FIFO
411        - added FX sends, these allow to route audio signals to arbitrary audio
412          output channels for being processed by external effect processors
413          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
414          controllers
415        - global (sampler wide) volume can now be controlled at runtime
416        - Implemented new, improved notification system
417        - fixed compilation errors regarding OSX
418          (patch by Toshi Nagata)
419        - implemented instruments database
420        - added support for escape sequences to the instruments database
421        - added highly experimental support for on-the-fly instrument editing
422          within the sampler's process (by using instrument editor plugins),
423          you'll notice the new "Registered instrument editors:" message on
424          startup, added a new LSCP command:
425          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
426          to spawn a matching instrument editor for the instrument on the
427          given sampler channel, the plugin path can be overridden at compile
428          time with ./configure --enable-plugin-dir=/some/dir
429        - added experimental code for synchronizing instrument editors hosted
430          in the sampler's process to safely edit instruments while playing
431          without a crash (hopefully) by either suspending single regions
432          wherever possible or if unavoidable whole engine(s)
433        - fixed several issues in fundamental "Thread" class: set scheduling
434          policy and priority on thread level, set a minimum stack size for
435          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
436          threads simply inherited properties of starting thread instead of
437          setting their own policy and priority
438        - minor fix in our automatic stack trace mechanism on crashes, the
439          main process did not wait for the stack trace process to finish
440          its output
441        - fixed some minor memory leaks
442        - reenabled assembly features support, at the moment only for
443          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
444        - minor assembly fix in x86 features detection (don't use the PIC
445          register, to avoid relocations in the text segment at runtime)
446        - POSIX callback functions of Thread.h are hidden
447    
448      * MIDI driver:
449        - dispatch bank select (MSB and LSB) messages
450    
451      * audio driver:
452        - the ALSA audio output driver parameters now reflect the correct
453          parameter value ranges for the respective selected sound card
454          (patch by Till Wimmer, a bit fixed and extended)
455    
456      * Gigasampler format engine:
457        - if a filter is used and EG2 finishes before EG1, let the voice
458          die when EG2 has finished (this fixes a problem with clicks and
459          voice starvation for some gigs)
460        - playback is no longer disabled during instrument loading
461        - all notes playing on a channel that changes its instrument keep
462          playing with the old instrument until they get a note off
463          command
464        - EG fix: a release value of zero could cause noises or crash
465        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
466        - EG fine tuning: when attack is zero the EG starts at a level
467          above max sustain level, which means that there is a decay phase
468          even if sustain is 100%
469        - more EG fixes: the level could sometimes go below zero and cause
470          noises or crashes
471        - minor fix of EGDecay (patch by Toshi Nagata)
472        - fixed compiler error when --enable-override-filter-type was
473          supplied to the configure script (fixes #46)
474        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
475          instead of a fix value
476        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
477          127 (solo mode) only kill voices if the respective mode really
478          changed
479    
480      * LSCP server:
481        - fixed compile time error for old Bison versions
482          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
483        - parser now supports extended ASCII character set
484          (up to ASCII code 255, i.e. includes now umlauts and accents)
485        - filename arguments in LSCP commands now allow to use escape
486          sequences, that is directly literal as one of: \', \", \\, \n, \r,
487          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
488          code value like \xf2) (fixes bug #24)
489        - the following LSCP commands now also support escape sequences for at
490          least one of their text-based parameters (i.e. name, description):
491          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
492          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
493          "SET DB_INSTRUMENT_DIRECTORY NAME",
494          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
495          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
496          "FIND DB_INSTRUMENT_DIRECTORIES"
497        - returns verbose syntax errors (line and column where syntax error
498          occured, the unexpected character and the actually expected, possible
499          character(s), the latter only if less than 5 possibilities)
500        - made sure that LSCP syntax is not affected by gigedit locale
501          settings
502        - bugfix regarding strings parameter lists: all comma separated lists
503          of strings were treated as being one string containing commas
504          (fixes #57)
505    
506      * Bug fixes:
507        - fixed crash occurring on certain LSCP scripts (Bug 39)
508        - another thread safety fix for lscp "load engine" and "set
509          channel audio output device"
510        - fixed a crash which occurs when reassigning the same engine
511          on a sampler channel with connected MIDI device
512        - fixed a crash which occurs when changing the number of ports of a MIDI
513          device connected to a sampler channel to number less then or equal
514          to the index of the port to which the sampler channel is connected.
515        - The previous bindings were not been disconnected when altering
516          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
517          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
518        - The active stream/voice count statistic was incorrect.
519        - notification events were not been sent for some sampler
520          channel changes
521        - added default min and max values to restrict the number of allowed
522          audio output channels and MIDI input ports
523        - the connection to the PCM interface is now closed when destroying
524          an audio output device
525        - files with slash in their path or filename could not be loaded
526    
527      * test cases:
528        - updated and fixed (haven't been touched in a while)
529    
530    Version 0.4.0 (24 November 2006)

532      * packaging changes:
533        - changed deprecated copyright attribute to license; added ldconfig
534          to post-(un)install steps; added devel package for liblinuxsampler;
535          to linuxsampler.spec (RPM)

569      - fixed bug in sysex handling (patch by Juan Linietsky)      - fixed bug in sysex handling (patch by Juan Linietsky)
570        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
571          which can be overridden with --enable-global-attenuation
572        - EG fixes: made the length of "attack hold" stage more
573          accurate. Release stage can now start before attack stage
574          ends. Cancel release didn't work when sustain was zero. Attack
575          time now has a minimal value to prevent clicks.
576        - fixed pitch changes larger than one octave
577        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
578        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
579          all modes can be altered via standard GM messages, that is CC5 for
580          altering portamento time, CC65 for enabling / disabling portamento
581          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
582        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
583          parameter) and crossfade
584        - added support for the "attenuation controller threshold" gig
585          parameter
586        - added smoothing of volume changes caused by control change
587          messages
588        - sample loop parameters are now taken from the DimensionRegion
589          instead of the wave chunk
590        - fixed keyswitching for v3 gigs with a number of keyswitch splits
591          not equal to a power of two
592        - reimplementation of the filter algorithm. The new filter is more
593          accurate and supports all gig filter types, including bandreject
594          and lowpass turbo.
595        - real support for 24 bit samples - samples are not truncated to
596          16 bits anymore
597        - support for aftertouch (channel pressure, not polyphonic
598          aftertouch)
599        - LFO1 behaviour fixed (dampening from max volume instead of
600          amplifying from 0)
