# Line 1  Line 1 
1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3      * General changes:
4        - Refactoring: moved the independent code from
5          the Gigasampler format engine to base classes
6        - command line option '--profile' is currently disabled, since the
7          respective profiling code is currently broken
8        - Introduced support for optional environment variable
9          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
10          where the sampler shall look for instrument editor plugins
11          (patch by Luis Garrido, slightly modified).
12    
13      * Gigasampler format engine:
14        - implemented the "round robin keyboard" dimension
15        - fixed round robin and random dimensions for cases when number of
16          dimension zones is not a power of two
17        - made round robin use a counter for each region instead of each
18          key
19    
20      * SFZ format engine:
21        - Initial implementation (not usable yet)
22        - added support for v2 multiple stage envelope generators
23        - added a fine-tuned v1 envelope generator instead of using the
24          one from the gig engine
25    
26      * SoundFont format engine:
27        - Initial implementation (not usable yet)
28    
29      * Host plugins:
30        - AU bugfix: failed to destroy its audio/MIDI devices
31        - Listen to all interfaces on Mac OS X (INADDR_ANY)
32        - VST bugfix: If the host called resume() before and after
33          changing sample rate or block size, the number of channels was
34          incorrectly set to two. This caused silence in Cubase 5.
35    
36      * MIDI driver:
37        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
38          the ALSA sequencer client name
39    
40      * LSCP server:
41        - added support for sending MIDI CC messages via LSCP command
42          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
43    
44      * Bug fixes:
45        - Fixed crash which may occur when MIDI key + transpose is out of range
46    
47    Version 1.0.0 (31 July 2009)
48    
49      * packaging changes:
50        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
51          causing e.g. the libgig test to fail when
52          "./configure --disable-jack-driver" was used
53          (patch by Alexis Ballier)
54        - fixed compilation with gcc 4.3
55        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
56        - fixed configure so it detects x86_64 (#107)
57        - fixes for building with newer MinGW versions
58        - fix for building with bison 2.4 (#111)
59        - fixed building with libgig installed in a non-standard directory
60        - minor fix in configure for mmsystem.h detection on MinGW
61        - Windows: look for editor plugins and Fantasia using base
62          directory of liblinuxsampler dll (look in the same directory and one
63          directory above)
64        - configure script fix: removed unconditional use of SSE
65        - fixed building with sqlite installed in a non-standard directory
66        - when cross-compiling, don't try to create instruments.db
67        - fix for new mingw-w64 version, which has usleep
68    
69      * general changes:
70        - bugfix: on some POSIX systems instrument editor plugins refused to
71          load as we used a non-portable Linux specific struct field
72          (fixes bug #70, patch by Ronald Baljeu)
73        - fixed endless loop which occured when loading an instrument editor
74          plugin DLL on Windows systems failed
75        - fixed memory leaks that occurred when liblinuxsampler was unloaded
76        - optimized the SynchronizedConfig class so it doesn't wait
77          unnecessarily long after an update
78        - added support for notifying instrument editors on note-on / note-off
79          events (e.g. to highlight the pressed keys on the virtual keyboard
80          of gigedit)
81        - added support for triggering notes by instrument editors (see above)
82        - be verbose on DLL load errors (on Linux)
83        - fixed di-harmonic triangle LFO implementation (this LFO implementation
84          is only used by very few systems, most pick the int math
85          implementation, which is usually faster)
86        - fixes for audio drivers with varying buffer sizes
87        - experimental support for running LinuxSampler as a DSSI, LV2 and
88          VST plugin
89        - notification events for stream/voice count statistics are now sent
90          only when there are actual changes
91        - added memory ordering constraints to improve stability on
92          multi-core and multi-cpu systems
93        - maximum voices and disk streams can now be altered at runtime
94        - fixed CPU feature detection on x86_64 (maybe fixes #108)
95        - automatic stacktrace mechanism is now turned off by default and can
96          be switched on by command line option "--stacktrace" (the automatic
97          stacktrace mechanism seems to be broken on most systems at the moment)
98        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
99          a pointer to the launched InstrumentEditor object
100        - added optional 3rd party user data parameter for following
101          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
102          InstrumentEditor::Launch(),
103          InstrumentManager::LaunchInstrumentEditor()
104        - theoretical fix: made SynchronizedConfig follow C++0x memory
105          model more strictly
106        - fixes for using large audio device buffers
107        - Windows: add the installation directory to the DLL search path
108          when loading an editor plugin (solves problems with VST and
109          gigedit on systems with other GTK versions installed)
110    
111      * audio driver:
112        - removed the nonsense audio channel constraint (which was hard coded to
113          max. 100 audio channels) for most audio drivers
114        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
115          opposed to the LSCP specs
116        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
117          reflected the wrong value
118        - fixed a memory management bug in ASIO driver
119        - Makefile fix: JACK_CFLAGS wasn't used
120        - JACK: use jack_client_open instead of the deprecated
121          jack_client_new
122        - added (experimental) CoreAudio driver
123        - applied old fixes to the ASIO driver that were included in the
124          previous binary release but accidentally never committed to CVS
125          (fixes #117)
126        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
127          win64)
128        - VST: added support for sample rate and buffer size changes
129        - VST: close editor (Fantasia) when the VST is removed
130        - VST: avoid opening Fantasia more than once for each VST instance
131        - VST: export main function as "main" on Linux too (fix for
132          energyXT)
133        - VST: changed number of output channels from one stereo to 16
134          stereo
135        - added channel routing, fxsends and midi maps to the settings
136          stored in the plugin state
137        - performance optimization of AudioChannel::MixTo() and
138          AudioChannel::CopyTo() methods using GCC vector exensions
139          (if available)
140        - ASIO fixes: avoid initializing the device twice, avoid throwing
141          exception when getting parameters from a disconnected device
142    
143      * MIDI driver:
144        - added JACK MIDI driver
145        - dispatch bank select as ordinary CC as well, the user might seriously
146          want to (mis)use it for some purpose ("fixed" in all current MIDI
147          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
148        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
149          CoreMidi or AU
150        - fixed mingw-w64 compilation error in MME driver
151        - made program change handling in MIDI thread real-time safe by
152          moving the logic to a non-RT thread
153        - fixed minor memory leak in ALSA driver
154    
155      * instruments database:
156        - avoid time consuming samples scanning when adding instruments
157          to the instruments database
158        - added support for handling lost files in the instruments database
159        - Implemented option for adding instruments in separate directories
160          in the instruments database
161          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
162        - work-around for missing fnmatch function on Windows to make
163          instrument database compilable
164        - added instrument database support on Windows
165          works with both standalone mode and VST plugin.
166          the instruments DB file is located in
167          %USERPROFILE%\.linuxsampler\instruments.db which allows different
168          databases for each windows user
169          if no DB is present it automatically creates the .linuxsampler subdir
170          and then creates an empty DB
171        - fixed recursive import, which was broken on Windows
172    
173      * Gigasampler format engine:
174        - fixed a memory leak that could happen when a channel was deleted
175          while notes were playing
176        - made it possible to load an instrument even if the audio thread
177          isn't running
178        - added partial support for the "Controller Triggered" MIDI rule,
179          enough for piano gigs with pedal noise samples
180        - minor fix: only mark FX sends as being modified if really the
181          respective FX send MIDI controller was used
182        - added support for GM global device volume SysEx message
183          (can be selected at compile time to either apply globally to the
184          whole sampler [default] or only to the sampler channels that are
185          connected to the respective MIDI input port the SysEx message arrived
186          on)
187        - bugfix: notes triggered at position 0 in the audio buffer were
188          sometimes wrongly killed in the same buffer, causing no sound to
189          be played
190        - added support for chromatic / drumkit mode Roland GS Sysex message
191          which is usally used to switch a part between chromatic sounds and
192          drumkit sounds (as opposed to their common default setting of MIDI
193          part 10 being a drumkit part and all other ones chromatic parts), in
194          LS however one can switch between the first 16 MIDI instrument maps
195          defined for the sampler
196        - made it possible to create multiple sample channels even if the
197          audio thread isn't running
198        - fixed crash when removing channel with active voices (#116)
199        - bugfix: on sample reference changes (instrument editor), only
200          un-cache the respective sample if it's really not used by any
201          sampler engine anymore
202        - re-cache samples in case they were changed by an instrument editor,
203          e.g. when a sample was added while playing (#82)
204        - fixed hanging notes which occured when note-off event had the exact
205          same time stamp as the voice's note-on event and occured both in the
206          same audio fragment cycle (fixes bug #112)
207        - added support for the "fine tune" and "pitch bend range"
208          instrument-level gig parameters
209        - fixed minor artifacts in pitch bend handling
210        - added support for GS Reset SysEx message
211        - allow gig files to use unlimited downward pitch shifting
212        - added a limit check for upward pitch shifting
213        - bugfix: sometimes, when playing a note twice fast, the second
214          note was silent
215        - fixed crash happening when a pitch bend event arrived at the
216          same time a new instrument was loading
217    
218      * LSCP server:
219        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
220          react on MIDI data arriving on certain sampler channels (so far only
221          Note-On and Note-Off events are sent via this LSCP event)
222        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
223          react on MIDI data arriving on certain MIDI input devices (so far only
224          Note-On and Note-Off events are sent via this LSCP event)
225        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
226          SET DB_INSTRUMENT FILE_PATH
227        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
228          frontends to send MIDI messages to specific sampler channel
229        - added two additional fields to GET FILE INSTRUMENT INFO command -
230          KEY_BINDINGS and KEYSWITCH_BINDINGS
231        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
232          was incorrect
233        - Optimized the retrieval of the MIDI instrument mappings
234        - added new LSCP command "SET VOICES" to globally alter the maximum
235          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
236          be triggered respectively
237        - added new LSCP command "SET STREAMS" to globally alter the maximum
238          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
239          which will be triggered respectively
240        - bugfix: retry if "select" returns EINTR (this fixes a crash when
241          a gigedit file dialog is opened)
242        - close all connections when LSCPServer is deleted
243        - hard close of all sockets on exit
244        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
245          driver
246    
247      * Bug fixes:
248        - fixed a crash which occurs when removing a sampler channel waiting
249          to start instrument loading after another channel
250        - fixed a crash which occurs when removing a sampler channel with
251          instrument loading in progress (bug #113)
252        - fixed termination caused by uncaught exception when adding MIDI
253          instrument with PERSISTENT load mode
254        - fixed possible iterator invalidations when resetting the sampler
255        - fixed memory leaks when issuing the following LSCP commands:
256          GET AUDIO_OUTPUT_DRIVER INFO
257          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
258          GET MIDI_INPUT_DRIVER INFO
259          GET MIDI_INPUT_DRIVER_PARAMETER INFO
260        - fixed possible compilation error when sqlite is not present
261        - fixed orphaned pointers when setting maximum voices limit (bug #118)
262        - fixed crash when changing the audio output device of a sampler
263          channel with loaded instrument and start playing notes
264        - fixed endless loop in Engine::SuspendAll() (bug #120)
265        - fixed a low-level atomic load function that was broken on 64-bit
266          PowerPC, which probably could cause crashes on that platform
267        - fixed a memory management error which could cause a crash when a
268          plugin was unloaded
269        - bugfix: two private structs had the same name, which could cause
270          problems if the linker chose the wrong constructor
271        - fixed low-level ConditionServer usage bug that caused lockups on
272          Windows
273    
274    
275    Version 0.5.1 (6 December 2007)
276    
277    * packaging changes:    * packaging changes:
278        - added autoconf checks for pthread library
279        - added autoconf check for pthread bug found on certain NPTL-enabled
280          glibc versions (see Gentoo bug report #194076)
281        - added autoconf checks for MS Windows
282    
283      * general changes:
284        - bugfix: the thread used by an editor plugin didn't die when the
285          editor closed
286        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
287          out all the space. operator--() did not apply size_mask after
288          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
289          order to avoid problems with the _NonVolatileReader functions.
290        - bugfix: Stream.h: added a missing divide by BytesPerSample in
291          GetWriteSpace(). Since this function is currently only used in
292          the stream's qsort() compare function, it didn't trigger any
293          bugs.
294        - Resampler.h, Synthesizer.h: cubic interpolation now works in
295          24bit mode too. Faster method to read 24bit words on little
296          endian machines (x86): replaced 3 byte reads + shifts with a 1
297          unaligned 32bit read and shift
298        - experimental support for MS Windows (MIDI input via MME, AUDIO
299          output via ASIO)
300        - made handling of SIGINT signal (Ctrl-C) a bit more robust
301        - support for monitoring the total number of active disk streams
302          (new LSCP commands: GET TOTAL_STREAM_COUNT,
303          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
304    
305      * AUDIO driver:
306        - added Windows ASIO low latency audio driver
307    
308      * MIDI driver:
309        - added MME Windows MIDI driver
310    
311      * LSCP server:
312        - added support for Windows style path / filenames, however with
313          forward slash path separators instead of backslash
314          (i.e. "C:/foo/bar.gig")
315        - allow naughty liblscp to send non-string device parameters within
316          apostrophes as well
317        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
318          "LIST FILE INSTRUMENTS <file>" and
319          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
320          about an arbitrary instrument file on the system where the sampler is
321          running on
322    
323    Version 0.5.0 (15 October 2007)
324    
325      * packaging changes:
326        - config.h is not going to be installed along with liblinuxsampler's
327          API header files anymore
328        - only the API relevant header (and source) files will be exported to
329          the Doxygen API documentation (explicitly listed in Doxyfile.in)
330        - added completely new XCode project files for Mac OSX which is now
331          capable to execute our autoconf environment, thus no need anymore
332          to maintain the compile time configuration file (osx/version.h) for
333          OSX manually (patch by Toshi Nagata)
334        - fixed buggy boolean --enable-foo / --disable-foo configure script
335          parameters
336        - global.h now only covers global definitions that are needed for the
337          C++ API header files, all implementation internal global definitions
338          are now in global_private.h
339        - atomic.h is not exposed to the C++ API anymore
340        - no need to include config.h anymore for using LS's API header files
341        - fixed warnings in API doc generation
342    
343      * general changes:
344        - replaced the old, confusing MIDI program change mechanism by a
345          flexible MIDI instrument mapper which allows to map arbitrary
346          (MIDI bank, MIDI program) pairs with arbitrary
347          (engine type, instrument file, file index) triplets which will be
348          loaded on the respective channel when such MIDI program change
349          messages arrive, beside that, each entry allows to define a life-time
350          strategy for the instrument, so the user can define whether the
351          instrument should i.e. be permanently loaded (to be able to switch
352          quickly among sounds) or i.e. loaded just on demand when the
353          respective program change arrives (to safe RAM space), as well as a
354          global volume factor for each entry, so the user can adjust the volume
355          dynamic of his mapped instrument collection without having to modify
356          the instrument files, also one can manage arbitrary amount of such
357          MIDI instrument maps and assign each sampler channel individually
358          a certain map, so that i.e. separation of normal instruments and
359          drumkits is possible
360        - new notification events for tracking changes to audio/MIDI devices,
361          MIDI instrument maps, MIDI instruments, FX sends, global volume.
362        - sampler was limited to load max. 200 instruments in the background
363          due to a constant size RingBuffer FIFO which is now replaced by a
364          dynamic (unlimited) size std::list FIFO
365        - added FX sends, these allow to route audio signals to arbitrary audio
366          output channels for being processed by external effect processors
367          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
368          controllers
369        - global (sampler wide) volume can now be controlled at runtime
370        - Implemented new, improved notification system
371        - fixed compilation errors regarding OSX
372          (patch by Toshi Nagata)
373        - implemented instruments database
374        - added support for escape sequences to the instruments database
375        - added highly experimental support for on-the-fly instrument editing
376          within the sampler's process (by using instrument editor plugins),
377          you'll notice the new "Registered instrument editors:" message on
378          startup, added a new LSCP command:
379          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
380          to spawn a matching instrument editor for the instrument on the
381          given sampler channel, the plugin path can be overridden at compile
382          time with ./configure --enable-plugin-dir=/some/dir
383        - added experimental code for synchronizing instrument editors hosted
384          in the sampler's process to safely edit instruments while playing
385          without a crash (hopefully) by either suspending single regions
386          wherever possible or if unavoidable whole engine(s)
387        - fixed several issues in fundamental "Thread" class: set scheduling
388          policy and priority on thread level, set a minimum stack size for
389          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
390          threads simply inherited properties of starting thread instead of
391          setting their own policy and priority
392        - minor fix in our automatic stack trace mechanism on crashes, the
393          main process did not wait for the stack trace process to finish
394          its output
395        - fixed some minor memory leaks
396        - reenabled assembly features support, at the moment only for
397          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
398        - minor assembly fix in x86 features detection (don't use the PIC
399          register, to avoid relocations in the text segment at runtime)
400        - POSIX callback functions of Thread.h are hidden
401    
402      * MIDI driver:
403        - dispatch bank select (MSB and LSB) messages
404    
405      * audio driver:
406        - the ALSA audio output driver parameters now reflect the correct
407          parameter value ranges for the respective selected sound card
408          (patch by Till Wimmer, a bit fixed and extended)
409    
410      * Gigasampler format engine:
411        - if a filter is used and EG2 finishes before EG1, let the voice
412          die when EG2 has finished (this fixes a problem with clicks and
413          voice starvation for some gigs)
414        - playback is no longer disabled during instrument loading
415        - all notes playing on a channel that changes its instrument keep
416          playing with the old instrument until they get a note off
417          command
418        - EG fix: a release value of zero could cause noises or crash
419        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
420        - EG fine tuning: when attack is zero the EG starts at a level
421          above max sustain level, which means that there is a decay phase
422          even if sustain is 100%
423        - more EG fixes: the level could sometimes go below zero and cause
424          noises or crashes
425        - minor fix of EGDecay (patch by Toshi Nagata)
426        - fixed compiler error when --enable-override-filter-type was
427          supplied to the configure script (fixes #46)
428        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
429          instead of a fix value
430        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
431          127 (solo mode) only kill voices if the respective mode really
432          changed
433    
434      * LSCP server:
435        - fixed compile time error for old Bison versions
436          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
437        - parser now supports extended ASCII character set
438          (up to ASCII code 255, i.e. includes now umlauts and accents)
439        - filename arguments in LSCP commands now allow to use escape
440          sequences, that is directly literal as one of: \', \", \\, \n, \r,
441          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
442          code value like \xf2) (fixes bug #24)
443        - the following LSCP commands now also support escape sequences for at
444          least one of their text-based parameters (i.e. name, description):
445          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
446          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
447          "SET DB_INSTRUMENT_DIRECTORY NAME",
448          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
449          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
450          "FIND DB_INSTRUMENT_DIRECTORIES"
451        - returns verbose syntax errors (line and column where syntax error
452          occured, the unexpected character and the actually expected, possible
453          character(s), the latter only if less than 5 possibilities)
454        - made sure that LSCP syntax is not affected by gigedit locale
455          settings
456        - bugfix regarding strings parameter lists: all comma separated lists
457          of strings were treated as being one string containing commas
458          (fixes #57)
459    
460      * Bug fixes:
461        - fixed crash occurring on certain LSCP scripts (Bug 39)
462        - another thread safety fix for lscp "load engine" and "set
463          channel audio output device"
464        - fixed a crash which occurs when reassigning the same engine
465          on a sampler channel with connected MIDI device
466        - fixed a crash which occurs when changing the number of ports of a MIDI
467          device connected to a sampler channel to number less then or equal
468          to the index of the port to which the sampler channel is connected.
469        - The previous bindings were not been disconnected when altering
470          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
471          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
472        - The active stream/voice count statistic was incorrect.
473        - notification events were not been sent for some sampler
474          channel changes
475        - added default min and max values to restrict the number of allowed
476          audio output channels and MIDI input ports
477        - the connection to the PCM interface is now closed when destroying
478          an audio output device
479        - files with slash in their path or filename could not be loaded
480    
481      * test cases:
482        - updated and fixed (haven't been touched in a while)
483    
484    Version 0.4.0 (24 November 2006)
485    
486      * packaging changes:
487        - changed deprecated copyright attribute to license; added ldconfig
488          to post-(un)install steps; added devel package for liblinuxsampler;
489          to linuxsampler.spec (RPM)
490      - install necessary development header files for allowing 3rd party      - install necessary development header files for allowing 3rd party
491        applications to link against liblinuxsampler        applications to link against liblinuxsampler
492      - liblinuxsampler's API documentation can be generated with 'make docs'      - liblinuxsampler's API documentation can be generated with 'make docs'
493        (Doxygen required)        (Doxygen required)
494        - added benchmark to automatically detect the best triangle LFO
495          implementation (currently either an integer math solution or a
496          di-harmonic approximation), automatic detection can be overriden
497          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
498          configure script argument though (mandatory for cross-compilation)
499        - do not automatically pick optimized gcc flags if the user already
500          provided some on his own (as CXXFLAGS)
501        - added compile time option to disable processing of All-Notes-Off MIDI
502          messages
503        - added compile time options to allow disabling the various audio and
504          MIDI drivers
505        - fixed automatic GCC CPU switch detection on PPC
506          (patch by Ebrahim Mayat)
507    
508    * Gigasampler format engine:    * Gigasampler format engine:
509        - extensive synthesis optimization
510          (reimplementation of EGs and LFO(s), removed synthesis parameter
511          prerendering and the synthesis parameter matrix in general, splitting
512          each audio fragment into subfragments now where each subfragment uses
513          constant pitch and filter coefficients. The volume coefficient is
514          linearly interpolated inside a subfragment, unless
515          --disable-interpolate-volume is set.)
516      - fine tuning of the EG modulation parameters      - fine tuning of the EG modulation parameters
517        - improved filter cutoff calculation by adding support for the
518          following gig parameters: Cutoff freq (used when no cutoff
519          controller is defined), Control invert, Minimum cutoff, Velocity
520          curve and Velocity range. The keyboard tracking now scales
521          cutoff frequency instead of resonance.
522        - added support for gig parameter Resonance.
523        - fixed bug in sysex handling (patch by Juan Linietsky)
524        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
525          which can be overridden with --enable-global-attenuation
526        - EG fixes: made the length of "attack hold" stage more
527          accurate. Release stage can now start before attack stage
528          ends. Cancel release didn't work when sustain was zero. Attack
529          time now has a minimal value to prevent clicks.
530        - fixed pitch changes larger than one octave
531        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
532        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
533          all modes can be altered via standard GM messages, that is CC5 for
534          altering portamento time, CC65 for enabling / disabling portamento
535          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
536        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
537          parameter) and crossfade
538        - added support for the "attenuation controller threshold" gig
539          parameter
540        - added smoothing of volume changes caused by control change
541          messages
542        - sample loop parameters are now taken from the DimensionRegion
543          instead of the wave chunk
544        - fixed keyswitching for v3 gigs with a number of keyswitch splits
545          not equal to a power of two
546        - reimplementation of the filter algorithm. The new filter is more
547          accurate and supports all gig filter types, including bandreject
548          and lowpass turbo.
549        - real support for 24 bit samples - samples are not truncated to
550          16 bits anymore
551        - support for aftertouch (channel pressure, not polyphonic
552          aftertouch)
553        - LFO1 behaviour fixed (dampening from max volume instead of
554          amplifying from 0)
555    
556      * LSCP server:
557        - fixed application exit on broken pipe error (fixes bug #20)
558        - fixed the notification messages delay due to lack of
559          network activity (fixes bug #26)
560        - fixed parser bug which occured on space(s) within device parameters
561          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
562    
563      * audio driver:
564        - added aRts audio output driver (by no means RT safe)
565    
566      * MIDI driver:
567        - fixed legacy sysex code which caused dispatching of MIDI SysEx
568          messages several times instead of once
569        - API extension for MIDI drivers which already supply exact time stamps
570          for events (i.e. for offline rendering based MIDI drivers)
571        - added checks for bad MIDI data
572    
573      * linuxsampler application:
574        - show available sampler engine types on startup
575    
576    * general changes:    * general changes:
577      - 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
578        LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new        LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
579        fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were        fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
580        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
581        (patch by Grigor Iliev, a bit adjusted)        (patch by Grigor Iliev, a bit adjusted). Also added configure option
582          --enable-process-muted-channels which can be used to enable the
583          processing of muted channels.
584        - support for sostenuto pedal
585        - support for monitoring the total number of active voices
586          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
587          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
588        - fixed some memory management errors
589        - fixed some concurrency problems that could lead to crashes when
590          LSCP commands were executed
591        - fixed crash when instrument loading failed previously on the same
592          sampler channel (fixes bug #36)
