# 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    
7      * Gigasampler format engine:
8        - implemented the "round robin keyboard" dimension
9        - fixed round robin and random dimensions for cases when number of
10          dimension zones is not a power of two
11        - made round robin use a counter for each region instead of each
12          key
13    
14      * SFZ format engine
15        - Initial implementation (not usable yet)
16    
17      * SoundFont format engine
18        - Initial implementation (not usable yet)
19    
20      * Host plugins:
21        - AU bugfix: failed to destroy its audio/MIDI devices
22        - Listen to all interfaces on Mac OS X (INADDR_ANY)
23        - VST bugfix: If the host called resume() before and after
24          changing sample rate or block size, the number of channels was
25          incorrectly set to two. This caused silence in Cubase 5.
26    
27      * MIDI driver:
28        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
29          the ALSA sequencer client name
30    
31      * LSCP server:
32        - added support for sending MIDI CC messages via LSCP command
33          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
34    
35      * Bug fixes:
36        - Fixed crash which may occur when MIDI key + transpose is out of range
37    
38    Version 1.0.0 (31 July 2009)
39    
40      * packaging changes:
41        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
42          causing e.g. the libgig test to fail when
43          "./configure --disable-jack-driver" was used
44          (patch by Alexis Ballier)
45        - fixed compilation with gcc 4.3
46        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
47        - fixed configure so it detects x86_64 (#107)
48        - fixes for building with newer MinGW versions
49        - fix for building with bison 2.4 (#111)
50        - fixed building with libgig installed in a non-standard directory
51        - minor fix in configure for mmsystem.h detection on MinGW
52        - Windows: look for editor plugins and Fantasia using base
53          directory of liblinuxsampler dll (look in the same directory and one
54          directory above)
55        - configure script fix: removed unconditional use of SSE
56        - fixed building with sqlite installed in a non-standard directory
57        - when cross-compiling, don't try to create instruments.db
58        - fix for new mingw-w64 version, which has usleep
59    
60      * general changes:
61        - bugfix: on some POSIX systems instrument editor plugins refused to
62          load as we used a non-portable Linux specific struct field
63          (fixes bug #70, patch by Ronald Baljeu)
64        - fixed endless loop which occured when loading an instrument editor
65          plugin DLL on Windows systems failed
66        - fixed memory leaks that occurred when liblinuxsampler was unloaded
67        - optimized the SynchronizedConfig class so it doesn't wait
68          unnecessarily long after an update
69        - added support for notifying instrument editors on note-on / note-off
70          events (e.g. to highlight the pressed keys on the virtual keyboard
71          of gigedit)
72        - added support for triggering notes by instrument editors (see above)
73        - be verbose on DLL load errors (on Linux)
74        - fixed di-harmonic triangle LFO implementation (this LFO implementation
75          is only used by very few systems, most pick the int math
76          implementation, which is usually faster)
77        - fixes for audio drivers with varying buffer sizes
78        - experimental support for running LinuxSampler as a DSSI, LV2 and
79          VST plugin
80        - notification events for stream/voice count statistics are now sent
81          only when there are actual changes
82        - added memory ordering constraints to improve stability on
83          multi-core and multi-cpu systems
84        - maximum voices and disk streams can now be altered at runtime
85        - fixed CPU feature detection on x86_64 (maybe fixes #108)
86        - automatic stacktrace mechanism is now turned off by default and can
87          be switched on by command line option "--stacktrace" (the automatic
88          stacktrace mechanism seems to be broken on most systems at the moment)
89        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
90          a pointer to the launched InstrumentEditor object
91        - added optional 3rd party user data parameter for following
92          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
93          InstrumentEditor::Launch(),
94          InstrumentManager::LaunchInstrumentEditor()
95        - theoretical fix: made SynchronizedConfig follow C++0x memory
96          model more strictly
97        - fixes for using large audio device buffers
98        - Windows: add the installation directory to the DLL search path
99          when loading an editor plugin (solves problems with VST and
100          gigedit on systems with other GTK versions installed)
101    
102      * audio driver:
103        - removed the nonsense audio channel constraint (which was hard coded to
104          max. 100 audio channels) for most audio drivers
105        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
106          opposed to the LSCP specs
107        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
108          reflected the wrong value
109        - fixed a memory management bug in ASIO driver
110        - Makefile fix: JACK_CFLAGS wasn't used
111        - JACK: use jack_client_open instead of the deprecated
112          jack_client_new
113        - added (experimental) CoreAudio driver
114        - applied old fixes to the ASIO driver that were included in the
115          previous binary release but accidentally never committed to CVS
116          (fixes #117)
117        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
118          win64)
119        - VST: added support for sample rate and buffer size changes
120        - VST: close editor (Fantasia) when the VST is removed
121        - VST: avoid opening Fantasia more than once for each VST instance
122        - VST: export main function as "main" on Linux too (fix for
123          energyXT)
124        - VST: changed number of output channels from one stereo to 16
125          stereo
126        - added channel routing, fxsends and midi maps to the settings
127          stored in the plugin state
128        - performance optimization of AudioChannel::MixTo() and
129          AudioChannel::CopyTo() methods using GCC vector exensions
130          (if available)
131        - ASIO fixes: avoid initializing the device twice, avoid throwing
132          exception when getting parameters from a disconnected device
133    
134      * MIDI driver:
135        - added JACK MIDI driver
136        - dispatch bank select as ordinary CC as well, the user might seriously
137          want to (mis)use it for some purpose ("fixed" in all current MIDI
138          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
139        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
140          CoreMidi or AU
141        - fixed mingw-w64 compilation error in MME driver
142        - made program change handling in MIDI thread real-time safe by
143          moving the logic to a non-RT thread
144        - fixed minor memory leak in ALSA driver
145    
146      * instruments database:
147        - avoid time consuming samples scanning when adding instruments
148          to the instruments database
149        - added support for handling lost files in the instruments database
150        - Implemented option for adding instruments in separate directories
151          in the instruments database
152          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
153        - work-around for missing fnmatch function on Windows to make
154          instrument database compilable
155        - added instrument database support on Windows
156          works with both standalone mode and VST plugin.
157          the instruments DB file is located in
158          %USERPROFILE%\.linuxsampler\instruments.db which allows different
159          databases for each windows user
160          if no DB is present it automatically creates the .linuxsampler subdir
161          and then creates an empty DB
162        - fixed recursive import, which was broken on Windows
163    
164      * Gigasampler format engine:
165        - fixed a memory leak that could happen when a channel was deleted
166          while notes were playing
167        - made it possible to load an instrument even if the audio thread
168          isn't running
169        - added partial support for the "Controller Triggered" MIDI rule,
170          enough for piano gigs with pedal noise samples
171        - minor fix: only mark FX sends as being modified if really the
172          respective FX send MIDI controller was used
173        - added support for GM global device volume SysEx message
174          (can be selected at compile time to either apply globally to the
175          whole sampler [default] or only to the sampler channels that are
176          connected to the respective MIDI input port the SysEx message arrived
177          on)
178        - bugfix: notes triggered at position 0 in the audio buffer were
179          sometimes wrongly killed in the same buffer, causing no sound to
180          be played
181        - added support for chromatic / drumkit mode Roland GS Sysex message
182          which is usally used to switch a part between chromatic sounds and
183          drumkit sounds (as opposed to their common default setting of MIDI
184          part 10 being a drumkit part and all other ones chromatic parts), in
185          LS however one can switch between the first 16 MIDI instrument maps
186          defined for the sampler
187        - made it possible to create multiple sample channels even if the
188          audio thread isn't running
189        - fixed crash when removing channel with active voices (#116)
190        - bugfix: on sample reference changes (instrument editor), only
191          un-cache the respective sample if it's really not used by any
192          sampler engine anymore
193        - re-cache samples in case they were changed by an instrument editor,
194          e.g. when a sample was added while playing (#82)
195        - fixed hanging notes which occured when note-off event had the exact
196          same time stamp as the voice's note-on event and occured both in the
197          same audio fragment cycle (fixes bug #112)
198        - added support for the "fine tune" and "pitch bend range"
199          instrument-level gig parameters
200        - fixed minor artifacts in pitch bend handling
201        - added support for GS Reset SysEx message
202        - allow gig files to use unlimited downward pitch shifting
203        - added a limit check for upward pitch shifting
204        - bugfix: sometimes, when playing a note twice fast, the second
205          note was silent
206        - fixed crash happening when a pitch bend event arrived at the
207          same time a new instrument was loading
208    
209      * LSCP server:
210        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
211          react on MIDI data arriving on certain sampler channels (so far only
212          Note-On and Note-Off events are sent via this LSCP event)
213        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
214          react on MIDI data arriving on certain MIDI input devices (so far only
215          Note-On and Note-Off events are sent via this LSCP event)
216        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
217          SET DB_INSTRUMENT FILE_PATH
218        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
219          frontends to send MIDI messages to specific sampler channel
220        - added two additional fields to GET FILE INSTRUMENT INFO command -
221          KEY_BINDINGS and KEYSWITCH_BINDINGS
222        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
223          was incorrect
224        - Optimized the retrieval of the MIDI instrument mappings
225        - added new LSCP command "SET VOICES" to globally alter the maximum
226          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
227          be triggered respectively
228        - added new LSCP command "SET STREAMS" to globally alter the maximum
229          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
230          which will be triggered respectively
231        - bugfix: retry if "select" returns EINTR (this fixes a crash when
232          a gigedit file dialog is opened)
233        - close all connections when LSCPServer is deleted
234        - hard close of all sockets on exit
235        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
236          driver
237    
238      * Bug fixes:
239        - fixed a crash which occurs when removing a sampler channel waiting
240          to start instrument loading after another channel
241        - fixed a crash which occurs when removing a sampler channel with
242          instrument loading in progress (bug #113)
243        - fixed termination caused by uncaught exception when adding MIDI
244          instrument with PERSISTENT load mode
245        - fixed possible iterator invalidations when resetting the sampler
246        - fixed memory leaks when issuing the following LSCP commands:
247          GET AUDIO_OUTPUT_DRIVER INFO
248          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
249          GET MIDI_INPUT_DRIVER INFO
250          GET MIDI_INPUT_DRIVER_PARAMETER INFO
251        - fixed possible compilation error when sqlite is not present
252        - fixed orphaned pointers when setting maximum voices limit (bug #118)
253        - fixed crash when changing the audio output device of a sampler
254          channel with loaded instrument and start playing notes
255        - fixed endless loop in Engine::SuspendAll() (bug #120)
256        - fixed a low-level atomic load function that was broken on 64-bit
257          PowerPC, which probably could cause crashes on that platform
258        - fixed a memory management error which could cause a crash when a
259          plugin was unloaded
260        - bugfix: two private structs had the same name, which could cause
261          problems if the linker chose the wrong constructor
262        - fixed low-level ConditionServer usage bug that caused lockups on
263          Windows
264    
265    
266    Version 0.5.1 (6 December 2007)
267    
268      * packaging changes:
269        - added autoconf checks for pthread library
270        - added autoconf check for pthread bug found on certain NPTL-enabled
271          glibc versions (see Gentoo bug report #194076)
272        - added autoconf checks for MS Windows
273    
274      * general changes:
275        - bugfix: the thread used by an editor plugin didn't die when the
276          editor closed
277        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
278          out all the space. operator--() did not apply size_mask after
279          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
280          order to avoid problems with the _NonVolatileReader functions.
281        - bugfix: Stream.h: added a missing divide by BytesPerSample in
282          GetWriteSpace(). Since this function is currently only used in
283          the stream's qsort() compare function, it didn't trigger any
284          bugs.
285        - Resampler.h, Synthesizer.h: cubic interpolation now works in
286          24bit mode too. Faster method to read 24bit words on little
287          endian machines (x86): replaced 3 byte reads + shifts with a 1
288          unaligned 32bit read and shift
289        - experimental support for MS Windows (MIDI input via MME, AUDIO
290          output via ASIO)
291        - made handling of SIGINT signal (Ctrl-C) a bit more robust
292        - support for monitoring the total number of active disk streams
293          (new LSCP commands: GET TOTAL_STREAM_COUNT,
294          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
295    
296      * AUDIO driver:
297        - added Windows ASIO low latency audio driver
298    
299      * MIDI driver:
300        - added MME Windows MIDI driver
301    
302      * LSCP server:
303        - added support for Windows style path / filenames, however with
304          forward slash path separators instead of backslash
305          (i.e. "C:/foo/bar.gig")
306        - allow naughty liblscp to send non-string device parameters within
307          apostrophes as well
308        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
309          "LIST FILE INSTRUMENTS <file>" and
310          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
311          about an arbitrary instrument file on the system where the sampler is
312          running on
313    
314    Version 0.5.0 (15 October 2007)
315    
316      * packaging changes:
317        - config.h is not going to be installed along with liblinuxsampler's
318          API header files anymore
319        - only the API relevant header (and source) files will be exported to
320          the Doxygen API documentation (explicitly listed in Doxyfile.in)
321        - added completely new XCode project files for Mac OSX which is now
322          capable to execute our autoconf environment, thus no need anymore
323          to maintain the compile time configuration file (osx/version.h) for
324          OSX manually (patch by Toshi Nagata)
325        - fixed buggy boolean --enable-foo / --disable-foo configure script
326          parameters
327        - global.h now only covers global definitions that are needed for the
328          C++ API header files, all implementation internal global definitions
329          are now in global_private.h
330        - atomic.h is not exposed to the C++ API anymore
331        - no need to include config.h anymore for using LS's API header files
332        - fixed warnings in API doc generation
333    
334      * general changes:
335        - replaced the old, confusing MIDI program change mechanism by a
336          flexible MIDI instrument mapper which allows to map arbitrary
337          (MIDI bank, MIDI program) pairs with arbitrary
338          (engine type, instrument file, file index) triplets which will be
339          loaded on the respective channel when such MIDI program change
340          messages arrive, beside that, each entry allows to define a life-time
341          strategy for the instrument, so the user can define whether the
342          instrument should i.e. be permanently loaded (to be able to switch
343          quickly among sounds) or i.e. loaded just on demand when the
344          respective program change arrives (to safe RAM space), as well as a
345          global volume factor for each entry, so the user can adjust the volume
346          dynamic of his mapped instrument collection without having to modify
347          the instrument files, also one can manage arbitrary amount of such
348          MIDI instrument maps and assign each sampler channel individually
349          a certain map, so that i.e. separation of normal instruments and
350          drumkits is possible
351        - new notification events for tracking changes to audio/MIDI devices,
352          MIDI instrument maps, MIDI instruments, FX sends, global volume.
353        - sampler was limited to load max. 200 instruments in the background
354          due to a constant size RingBuffer FIFO which is now replaced by a
355          dynamic (unlimited) size std::list FIFO
356        - added FX sends, these allow to route audio signals to arbitrary audio
357          output channels for being processed by external effect processors
358          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
359          controllers
360        - global (sampler wide) volume can now be controlled at runtime
361        - Implemented new, improved notification system
362        - fixed compilation errors regarding OSX
363          (patch by Toshi Nagata)
364        - implemented instruments database
365        - added support for escape sequences to the instruments database
366        - added highly experimental support for on-the-fly instrument editing
367          within the sampler's process (by using instrument editor plugins),
368          you'll notice the new "Registered instrument editors:" message on
369          startup, added a new LSCP command:
370          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
371          to spawn a matching instrument editor for the instrument on the
372          given sampler channel, the plugin path can be overridden at compile
373          time with ./configure --enable-plugin-dir=/some/dir
374        - added experimental code for synchronizing instrument editors hosted
375          in the sampler's process to safely edit instruments while playing
376          without a crash (hopefully) by either suspending single regions
377          wherever possible or if unavoidable whole engine(s)
378        - fixed several issues in fundamental "Thread" class: set scheduling
379          policy and priority on thread level, set a minimum stack size for
380          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
381          threads simply inherited properties of starting thread instead of
382          setting their own policy and priority
383        - minor fix in our automatic stack trace mechanism on crashes, the
384          main process did not wait for the stack trace process to finish
385          its output
386        - fixed some minor memory leaks
387        - reenabled assembly features support, at the moment only for
388          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
389        - minor assembly fix in x86 features detection (don't use the PIC
390          register, to avoid relocations in the text segment at runtime)
391        - POSIX callback functions of Thread.h are hidden
392    
393      * MIDI driver:
394        - dispatch bank select (MSB and LSB) messages
395    
396      * audio driver:
397        - the ALSA audio output driver parameters now reflect the correct
398          parameter value ranges for the respective selected sound card
399          (patch by Till Wimmer, a bit fixed and extended)
400    
401      * Gigasampler format engine:
402        - if a filter is used and EG2 finishes before EG1, let the voice
403          die when EG2 has finished (this fixes a problem with clicks and
404          voice starvation for some gigs)
405        - playback is no longer disabled during instrument loading
406        - all notes playing on a channel that changes its instrument keep
407          playing with the old instrument until they get a note off
408          command
409        - EG fix: a release value of zero could cause noises or crash
410        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
411        - EG fine tuning: when attack is zero the EG starts at a level
412          above max sustain level, which means that there is a decay phase
413          even if sustain is 100%
414        - more EG fixes: the level could sometimes go below zero and cause
415          noises or crashes
416        - minor fix of EGDecay (patch by Toshi Nagata)
417        - fixed compiler error when --enable-override-filter-type was
418          supplied to the configure script (fixes #46)
419        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
420          instead of a fix value
421        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
422          127 (solo mode) only kill voices if the respective mode really
423          changed
424    
425      * LSCP server:
426        - fixed compile time error for old Bison versions
427          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
428        - parser now supports extended ASCII character set
429          (up to ASCII code 255, i.e. includes now umlauts and accents)
430        - filename arguments in LSCP commands now allow to use escape
431          sequences, that is directly literal as one of: \', \", \\, \n, \r,
432          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
433          code value like \xf2) (fixes bug #24)
434        - the following LSCP commands now also support escape sequences for at
435          least one of their text-based parameters (i.e. name, description):
436          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
437          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
438          "SET DB_INSTRUMENT_DIRECTORY NAME",
439          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
440          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
441          "FIND DB_INSTRUMENT_DIRECTORIES"
442        - returns verbose syntax errors (line and column where syntax error
443          occured, the unexpected character and the actually expected, possible
444          character(s), the latter only if less than 5 possibilities)
445        - made sure that LSCP syntax is not affected by gigedit locale
446          settings
447        - bugfix regarding strings parameter lists: all comma separated lists
448          of strings were treated as being one string containing commas
449          (fixes #57)
450    
451      * Bug fixes:
452        - fixed crash occurring on certain LSCP scripts (Bug 39)
453        - another thread safety fix for lscp "load engine" and "set
454          channel audio output device"
455        - fixed a crash which occurs when reassigning the same engine
456          on a sampler channel with connected MIDI device
457        - fixed a crash which occurs when changing the number of ports of a MIDI
458          device connected to a sampler channel to number less then or equal
459          to the index of the port to which the sampler channel is connected.
460        - The previous bindings were not been disconnected when altering
461          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
462          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
463        - The active stream/voice count statistic was incorrect.
464        - notification events were not been sent for some sampler
465          channel changes
466        - added default min and max values to restrict the number of allowed
467          audio output channels and MIDI input ports
468        - the connection to the PCM interface is now closed when destroying
469          an audio output device
470        - files with slash in their path or filename could not be loaded
471    
472      * test cases:
473        - updated and fixed (haven't been touched in a while)
474    
475    Version 0.4.0 (24 November 2006)
476    
477      * packaging changes:
478        - changed deprecated copyright attribute to license; added ldconfig
479          to post-(un)install steps; added devel package for liblinuxsampler;
480          to linuxsampler.spec (RPM)
481        - install necessary development header files for allowing 3rd party
482          applications to link against liblinuxsampler
483        - liblinuxsampler's API documentation can be generated with 'make docs'
484          (Doxygen required)
485        - added benchmark to automatically detect the best triangle LFO
486          implementation (currently either an integer math solution or a
487          di-harmonic approximation), automatic detection can be overriden
488          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
489          configure script argument though (mandatory for cross-compilation)
490        - do not automatically pick optimized gcc flags if the user already
491          provided some on his own (as CXXFLAGS)
492        - added compile time option to disable processing of All-Notes-Off MIDI
493          messages
494        - added compile time options to allow disabling the various audio and
495          MIDI drivers
496        - fixed automatic GCC CPU switch detection on PPC
497          (patch by Ebrahim Mayat)
498    
499      * Gigasampler format engine:
500        - extensive synthesis optimization
501          (reimplementation of EGs and LFO(s), removed synthesis parameter
502          prerendering and the synthesis parameter matrix in general, splitting
503          each audio fragment into subfragments now where each subfragment uses
504          constant pitch and filter coefficients. The volume coefficient is
505          linearly interpolated inside a subfragment, unless
506          --disable-interpolate-volume is set.)
507        - fine tuning of the EG modulation parameters
508        - improved filter cutoff calculation by adding support for the
509          following gig parameters: Cutoff freq (used when no cutoff
510          controller is defined), Control invert, Minimum cutoff, Velocity
511          curve and Velocity range. The keyboard tracking now scales
512          cutoff frequency instead of resonance.
513        - added support for gig parameter Resonance.
514        - fixed bug in sysex handling (patch by Juan Linietsky)
515        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
516          which can be overridden with --enable-global-attenuation
517        - EG fixes: made the length of "attack hold" stage more
518          accurate. Release stage can now start before attack stage
519          ends. Cancel release didn't work when sustain was zero. Attack
520          time now has a minimal value to prevent clicks.
521        - fixed pitch changes larger than one octave
522        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
523        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
524          all modes can be altered via standard GM messages, that is CC5 for
525          altering portamento time, CC65 for enabling / disabling portamento
526          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
527        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
528          parameter) and crossfade
529        - added support for the "attenuation controller threshold" gig
530          parameter
531        - added smoothing of volume changes caused by control change
532          messages
533        - sample loop parameters are now taken from the DimensionRegion
534          instead of the wave chunk
535        - fixed keyswitching for v3 gigs with a number of keyswitch splits
536          not equal to a power of two
537        - reimplementation of the filter algorithm. The new filter is more
538          accurate and supports all gig filter types, including bandreject
539          and lowpass turbo.
540        - real support for 24 bit samples - samples are not truncated to
541          16 bits anymore
542        - support for aftertouch (channel pressure, not polyphonic
543          aftertouch)
544        - LFO1 behaviour fixed (dampening from max volume instead of
545          amplifying from 0)
546    
547      * LSCP server:
548        - fixed application exit on broken pipe error (fixes bug #20)
549        - fixed the notification messages delay due to lack of
550          network activity (fixes bug #26)
551        - fixed parser bug which occured on space(s) within device parameters
552          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
553    
554      * audio driver:
555        - added aRts audio output driver (by no means RT safe)
556    
557      * MIDI driver:
558        - fixed legacy sysex code which caused dispatching of MIDI SysEx
559          messages several times instead of once
560        - API extension for MIDI drivers which already supply exact time stamps
561          for events (i.e. for offline rendering based MIDI drivers)
562        - added checks for bad MIDI data
563    
564      * linuxsampler application:
565        - show available sampler engine types on startup
566    
567      * general changes:
568        - support for muting sampler channels and solo mode of the same, two new
569          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
570          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
571          introduced for this, the behavior is the same like on a mixer console
572          (patch by Grigor Iliev, a bit adjusted). Also added configure option
573          --enable-process-muted-channels which can be used to enable the
574          processing of muted channels.
575        - support for sostenuto pedal
576        - support for monitoring the total number of active voices
577          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
578          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
579        - fixed some memory management errors
580        - fixed some concurrency problems that could lead to crashes when
581          LSCP commands were executed
582        - fixed crash when instrument loading failed previously on the same
583          sampler channel (fixes bug #36)
584    
585    Version 0.3.3 (15 July 2005)
586    
587    * packaging changes:    * packaging changes:
588      - fixed compilation with gcc 4.0      - fixed compilation with gcc 4.0
589    
590      * Gigasampler format engine:
591        - LFO preprocessing was performed even though the respective LFO was
592          disabled by the instrument patch (minor efficiency fix)
593        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
594          for volume ramp downs in the same fragment (needed for current voice
595          stealing implementation) then simply inform the user with a warning
596          about possible click sounds and reduce the volume ramp down
597          appropriately instead of cancelling the audio device connection
