# Line 1  Line 1 
1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3      * host plugins:
4        - AU bugfix: failed to destroy its audio/MIDI devices
5        - Listen to all interfaces on Mac OS X (INADDR_ANY)
6    
7      * MIDI driver:
8        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
9          the ALSA sequencer client name
10    
11    Version 1.0.0 (31 July 2009)
12    
13      * packaging changes:
14        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
15          causing e.g. the libgig test to fail when
16          "./configure --disable-jack-driver" was used
17          (patch by Alexis Ballier)
18        - fixed compilation with gcc 4.3
19        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
20        - fixed configure so it detects x86_64 (#107)
21        - fixes for building with newer MinGW versions
22        - fix for building with bison 2.4 (#111)
23        - fixed building with libgig installed in a non-standard directory
24        - minor fix in configure for mmsystem.h detection on MinGW
25        - Windows: look for editor plugins and Fantasia using base
26          directory of liblinuxsampler dll (look in the same directory and one
27          directory above)
28        - configure script fix: removed unconditional use of SSE
29        - fixed building with sqlite installed in a non-standard directory
30        - when cross-compiling, don't try to create instruments.db
31        - fix for new mingw-w64 version, which has usleep
32    
33      * general changes:
34        - bugfix: on some POSIX systems instrument editor plugins refused to
35          load as we used a non-portable Linux specific struct field
36          (fixes bug #70, patch by Ronald Baljeu)
37        - fixed endless loop which occured when loading an instrument editor
38          plugin DLL on Windows systems failed
39        - fixed memory leaks that occurred when liblinuxsampler was unloaded
40        - optimized the SynchronizedConfig class so it doesn't wait
41          unnecessarily long after an update
42        - added support for notifying instrument editors on note-on / note-off
43          events (e.g. to highlight the pressed keys on the virtual keyboard
44          of gigedit)
45        - added support for triggering notes by instrument editors (see above)
46        - be verbose on DLL load errors (on Linux)
47        - fixed di-harmonic triangle LFO implementation (this LFO implementation
48          is only used by very few systems, most pick the int math
49          implementation, which is usually faster)
50        - fixes for audio drivers with varying buffer sizes
51        - experimental support for running LinuxSampler as a DSSI, LV2 and
52          VST plugin
53        - notification events for stream/voice count statistics are now sent
54          only when there are actual changes
55        - added memory ordering constraints to improve stability on
56          multi-core and multi-cpu systems
57        - maximum voices and disk streams can now be altered at runtime
58        - fixed CPU feature detection on x86_64 (maybe fixes #108)
59        - automatic stacktrace mechanism is now turned off by default and can
60          be switched on by command line option "--stacktrace" (the automatic
61          stacktrace mechanism seems to be broken on most systems at the moment)
62        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
63          a pointer to the launched InstrumentEditor object
64        - added optional 3rd party user data parameter for following
65          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
66          InstrumentEditor::Launch(),
67          InstrumentManager::LaunchInstrumentEditor()
68        - theoretical fix: made SynchronizedConfig follow C++0x memory
69          model more strictly
70        - fixes for using large audio device buffers
71        - Windows: add the installation directory to the DLL search path
72          when loading an editor plugin (solves problems with VST and
73          gigedit on systems with other GTK versions installed)
74    
75      * audio driver:
76        - removed the nonsense audio channel constraint (which was hard coded to
77          max. 100 audio channels) for most audio drivers
78        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
79          opposed to the LSCP specs
80        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
81          reflected the wrong value
82        - fixed a memory management bug in ASIO driver
83        - Makefile fix: JACK_CFLAGS wasn't used
84        - JACK: use jack_client_open instead of the deprecated
85          jack_client_new
86        - added (experimental) CoreAudio driver
87        - applied old fixes to the ASIO driver that were included in the
88          previous binary release but accidentally never committed to CVS
89          (fixes #117)
90        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
91          win64)
92        - VST: added support for sample rate and buffer size changes
93        - VST: close editor (Fantasia) when the VST is removed
94        - VST: avoid opening Fantasia more than once for each VST instance
95        - VST: export main function as "main" on Linux too (fix for
96          energyXT)
97        - VST: changed number of output channels from one stereo to 16
98          stereo
99        - added channel routing, fxsends and midi maps to the settings
100          stored in the plugin state
101        - performance optimization of AudioChannel::MixTo() and
102          AudioChannel::CopyTo() methods using GCC vector exensions
103          (if available)
104        - ASIO fixes: avoid initializing the device twice, avoid throwing
105          exception when getting parameters from a disconnected device
106    
107      * MIDI driver:
108        - added JACK MIDI driver
109        - dispatch bank select as ordinary CC as well, the user might seriously
110          want to (mis)use it for some purpose ("fixed" in all current MIDI
111          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
112        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
113          CoreMidi or AU
114        - fixed mingw-w64 compilation error in MME driver
115        - made program change handling in MIDI thread real-time safe by
116          moving the logic to a non-RT thread
117        - fixed minor memory leak in ALSA driver
118    
119      * instruments database:
120        - avoid time consuming samples scanning when adding instruments
121          to the instruments database
122        - added support for handling lost files in the instruments database
123        - Implemented option for adding instruments in separate directories
124          in the instruments database
125          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
126        - work-around for missing fnmatch function on Windows to make
127          instrument database compilable
128        - added instrument database support on Windows
129          works with both standalone mode and VST plugin.
130          the instruments DB file is located in
131          %USERPROFILE%\.linuxsampler\instruments.db which allows different
132          databases for each windows user
133          if no DB is present it automatically creates the .linuxsampler subdir
134          and then creates an empty DB
135        - fixed recursive import, which was broken on Windows
136    
137      * Gigasampler format engine:
138        - fixed a memory leak that could happen when a channel was deleted
139          while notes were playing
140        - made it possible to load an instrument even if the audio thread
141          isn't running
142        - added partial support for the "Controller Triggered" MIDI rule,
143          enough for piano gigs with pedal noise samples
144        - minor fix: only mark FX sends as being modified if really the
145          respective FX send MIDI controller was used
146        - added support for GM global device volume SysEx message
147          (can be selected at compile time to either apply globally to the
148          whole sampler [default] or only to the sampler channels that are
149          connected to the respective MIDI input port the SysEx message arrived
150          on)
151        - bugfix: notes triggered at position 0 in the audio buffer were
152          sometimes wrongly killed in the same buffer, causing no sound to
153          be played
154        - added support for chromatic / drumkit mode Roland GS Sysex message
155          which is usally used to switch a part between chromatic sounds and
156          drumkit sounds (as opposed to their common default setting of MIDI
157          part 10 being a drumkit part and all other ones chromatic parts), in
158          LS however one can switch between the first 16 MIDI instrument maps
159          defined for the sampler
160        - made it possible to create multiple sample channels even if the
161          audio thread isn't running
162        - fixed crash when removing channel with active voices (#116)
163        - bugfix: on sample reference changes (instrument editor), only
164          un-cache the respective sample if it's really not used by any
165          sampler engine anymore
166        - re-cache samples in case they were changed by an instrument editor,
167          e.g. when a sample was added while playing (#82)
168        - fixed hanging notes which occured when note-off event had the exact
169          same time stamp as the voice's note-on event and occured both in the
170          same audio fragment cycle (fixes bug #112)
171        - added support for the "fine tune" and "pitch bend range"
172          instrument-level gig parameters
173        - fixed minor artifacts in pitch bend handling
174        - added support for GS Reset SysEx message
175        - allow gig files to use unlimited downward pitch shifting
176        - added a limit check for upward pitch shifting
177        - bugfix: sometimes, when playing a note twice fast, the second
178          note was silent
179        - fixed crash happening when a pitch bend event arrived at the
180          same time a new instrument was loading
181    
182      * LSCP server:
183        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
184          react on MIDI data arriving on certain sampler channels (so far only
185          Note-On and Note-Off events are sent via this LSCP event)
186        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
187          react on MIDI data arriving on certain MIDI input devices (so far only
188          Note-On and Note-Off events are sent via this LSCP event)
189        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
190          SET DB_INSTRUMENT FILE_PATH
191        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
192          frontends to send MIDI messages to specific sampler channel
193        - added two additional fields to GET FILE INSTRUMENT INFO command -
194          KEY_BINDINGS and KEYSWITCH_BINDINGS
195        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
196          was incorrect
197        - Optimized the retrieval of the MIDI instrument mappings
198        - added new LSCP command "SET VOICES" to globally alter the maximum
199          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
200          be triggered respectively
201        - added new LSCP command "SET STREAMS" to globally alter the maximum
202          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
203          which will be triggered respectively
204        - bugfix: retry if "select" returns EINTR (this fixes a crash when
205          a gigedit file dialog is opened)
206        - close all connections when LSCPServer is deleted
207        - hard close of all sockets on exit
208        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
209          driver
210    
211      * Bug fixes:
212        - fixed a crash which occurs when removing a sampler channel waiting
213          to start instrument loading after another channel
214        - fixed a crash which occurs when removing a sampler channel with
215          instrument loading in progress (bug #113)
216        - fixed termination caused by uncaught exception when adding MIDI
217          instrument with PERSISTENT load mode
218        - fixed possible iterator invalidations when resetting the sampler
219        - fixed memory leaks when issuing the following LSCP commands:
220          GET AUDIO_OUTPUT_DRIVER INFO
221          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
222          GET MIDI_INPUT_DRIVER INFO
223          GET MIDI_INPUT_DRIVER_PARAMETER INFO
224        - fixed possible compilation error when sqlite is not present
225        - fixed orphaned pointers when setting maximum voices limit (bug #118)
226        - fixed crash when changing the audio output device of a sampler
227          channel with loaded instrument and start playing notes
228        - fixed endless loop in Engine::SuspendAll() (bug #120)
229        - fixed a low-level atomic load function that was broken on 64-bit
230          PowerPC, which probably could cause crashes on that platform
231        - fixed a memory management error which could cause a crash when a
232          plugin was unloaded
233        - bugfix: two private structs had the same name, which could cause
234          problems if the linker chose the wrong constructor
235        - fixed low-level ConditionServer usage bug that caused lockups on
236          Windows
237    
238    
239    Version 0.5.1 (6 December 2007)
240    
241      * packaging changes:
242        - added autoconf checks for pthread library
243        - added autoconf check for pthread bug found on certain NPTL-enabled
244          glibc versions (see Gentoo bug report #194076)
245        - added autoconf checks for MS Windows
246    
247      * general changes:
248        - bugfix: the thread used by an editor plugin didn't die when the
249          editor closed
250        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
251          out all the space. operator--() did not apply size_mask after
252          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
253          order to avoid problems with the _NonVolatileReader functions.
254        - bugfix: Stream.h: added a missing divide by BytesPerSample in
255          GetWriteSpace(). Since this function is currently only used in
256          the stream's qsort() compare function, it didn't trigger any
257          bugs.
258        - Resampler.h, Synthesizer.h: cubic interpolation now works in
259          24bit mode too. Faster method to read 24bit words on little
260          endian machines (x86): replaced 3 byte reads + shifts with a 1
261          unaligned 32bit read and shift
262        - experimental support for MS Windows (MIDI input via MME, AUDIO
263          output via ASIO)
264        - made handling of SIGINT signal (Ctrl-C) a bit more robust
265        - support for monitoring the total number of active disk streams
266          (new LSCP commands: GET TOTAL_STREAM_COUNT,
267          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
268    
269      * AUDIO driver:
270        - added Windows ASIO low latency audio driver
271    
272      * MIDI driver:
273        - added MME Windows MIDI driver
274    
275      * LSCP server:
276        - added support for Windows style path / filenames, however with
277          forward slash path separators instead of backslash
278          (i.e. "C:/foo/bar.gig")
279        - allow naughty liblscp to send non-string device parameters within
280          apostrophes as well
281        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
282          "LIST FILE INSTRUMENTS <file>" and
283          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
284          about an arbitrary instrument file on the system where the sampler is
285          running on
286    
287    Version 0.5.0 (15 October 2007)
288    
289      * packaging changes:
290        - config.h is not going to be installed along with liblinuxsampler's
291          API header files anymore
292        - only the API relevant header (and source) files will be exported to
293          the Doxygen API documentation (explicitly listed in Doxyfile.in)
294        - added completely new XCode project files for Mac OSX which is now
295          capable to execute our autoconf environment, thus no need anymore
296          to maintain the compile time configuration file (osx/version.h) for
297          OSX manually (patch by Toshi Nagata)
298        - fixed buggy boolean --enable-foo / --disable-foo configure script
299          parameters
300        - global.h now only covers global definitions that are needed for the
301          C++ API header files, all implementation internal global definitions
302          are now in global_private.h
303        - atomic.h is not exposed to the C++ API anymore
304        - no need to include config.h anymore for using LS's API header files
305        - fixed warnings in API doc generation
306    
307      * general changes:
308        - replaced the old, confusing MIDI program change mechanism by a
309          flexible MIDI instrument mapper which allows to map arbitrary
310          (MIDI bank, MIDI program) pairs with arbitrary
311          (engine type, instrument file, file index) triplets which will be
312          loaded on the respective channel when such MIDI program change
313          messages arrive, beside that, each entry allows to define a life-time
314          strategy for the instrument, so the user can define whether the
315          instrument should i.e. be permanently loaded (to be able to switch
316          quickly among sounds) or i.e. loaded just on demand when the
317          respective program change arrives (to safe RAM space), as well as a
318          global volume factor for each entry, so the user can adjust the volume
319          dynamic of his mapped instrument collection without having to modify
320          the instrument files, also one can manage arbitrary amount of such
321          MIDI instrument maps and assign each sampler channel individually
322          a certain map, so that i.e. separation of normal instruments and
323          drumkits is possible
324        - new notification events for tracking changes to audio/MIDI devices,
325          MIDI instrument maps, MIDI instruments, FX sends, global volume.
326        - sampler was limited to load max. 200 instruments in the background
327          due to a constant size RingBuffer FIFO which is now replaced by a
328          dynamic (unlimited) size std::list FIFO
329        - added FX sends, these allow to route audio signals to arbitrary audio
330          output channels for being processed by external effect processors
331          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
332          controllers
333        - global (sampler wide) volume can now be controlled at runtime
334        - Implemented new, improved notification system
335        - fixed compilation errors regarding OSX
336          (patch by Toshi Nagata)
337        - implemented instruments database
338        - added support for escape sequences to the instruments database
339        - added highly experimental support for on-the-fly instrument editing
340          within the sampler's process (by using instrument editor plugins),
341          you'll notice the new "Registered instrument editors:" message on
342          startup, added a new LSCP command:
343          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
344          to spawn a matching instrument editor for the instrument on the
345          given sampler channel, the plugin path can be overridden at compile
346          time with ./configure --enable-plugin-dir=/some/dir
347        - added experimental code for synchronizing instrument editors hosted
348          in the sampler's process to safely edit instruments while playing
349          without a crash (hopefully) by either suspending single regions
350          wherever possible or if unavoidable whole engine(s)
351        - fixed several issues in fundamental "Thread" class: set scheduling
352          policy and priority on thread level, set a minimum stack size for
353          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
354          threads simply inherited properties of starting thread instead of
355          setting their own policy and priority
356        - minor fix in our automatic stack trace mechanism on crashes, the
357          main process did not wait for the stack trace process to finish
358          its output
359        - fixed some minor memory leaks
360        - reenabled assembly features support, at the moment only for
361          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
362        - minor assembly fix in x86 features detection (don't use the PIC
363          register, to avoid relocations in the text segment at runtime)
364        - POSIX callback functions of Thread.h are hidden
365    
366      * MIDI driver:
367        - dispatch bank select (MSB and LSB) messages
368    
369      * audio driver:
370        - the ALSA audio output driver parameters now reflect the correct
371          parameter value ranges for the respective selected sound card
372          (patch by Till Wimmer, a bit fixed and extended)
373    
374      * Gigasampler format engine:
375        - if a filter is used and EG2 finishes before EG1, let the voice
376          die when EG2 has finished (this fixes a problem with clicks and
377          voice starvation for some gigs)
378        - playback is no longer disabled during instrument loading
379        - all notes playing on a channel that changes its instrument keep
380          playing with the old instrument until they get a note off
381          command
382        - EG fix: a release value of zero could cause noises or crash
383        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
384        - EG fine tuning: when attack is zero the EG starts at a level
385          above max sustain level, which means that there is a decay phase
386          even if sustain is 100%
387        - more EG fixes: the level could sometimes go below zero and cause
388          noises or crashes
389        - minor fix of EGDecay (patch by Toshi Nagata)
390        - fixed compiler error when --enable-override-filter-type was
391          supplied to the configure script (fixes #46)
392        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
393          instead of a fix value
394        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
395          127 (solo mode) only kill voices if the respective mode really
396          changed
397    
398      * LSCP server:
399        - fixed compile time error for old Bison versions
400          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
401        - parser now supports extended ASCII character set
402          (up to ASCII code 255, i.e. includes now umlauts and accents)
403        - filename arguments in LSCP commands now allow to use escape
404          sequences, that is directly literal as one of: \', \", \\, \n, \r,
405          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
406          code value like \xf2) (fixes bug #24)
407        - the following LSCP commands now also support escape sequences for at
408          least one of their text-based parameters (i.e. name, description):
409          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
410          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
411          "SET DB_INSTRUMENT_DIRECTORY NAME",
412          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
413          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
414          "FIND DB_INSTRUMENT_DIRECTORIES"
415        - returns verbose syntax errors (line and column where syntax error
416          occured, the unexpected character and the actually expected, possible
417          character(s), the latter only if less than 5 possibilities)
418        - made sure that LSCP syntax is not affected by gigedit locale
419          settings
420        - bugfix regarding strings parameter lists: all comma separated lists
421          of strings were treated as being one string containing commas
422          (fixes #57)
423    
424      * Bug fixes:
425        - fixed crash occurring on certain LSCP scripts (Bug 39)
426        - another thread safety fix for lscp "load engine" and "set
427          channel audio output device"
428        - fixed a crash which occurs when reassigning the same engine
429          on a sampler channel with connected MIDI device
430        - fixed a crash which occurs when changing the number of ports of a MIDI
431          device connected to a sampler channel to number less then or equal
432          to the index of the port to which the sampler channel is connected.
433        - The previous bindings were not been disconnected when altering
434          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
435          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
436        - The active stream/voice count statistic was incorrect.
437        - notification events were not been sent for some sampler
438          channel changes
439        - added default min and max values to restrict the number of allowed
440          audio output channels and MIDI input ports
441        - the connection to the PCM interface is now closed when destroying
442          an audio output device
443        - files with slash in their path or filename could not be loaded
444    
445      * test cases:
446        - updated and fixed (haven't been touched in a while)
447    
448    Version 0.4.0 (24 November 2006)
449    
450      * packaging changes:
451        - changed deprecated copyright attribute to license; added ldconfig
452          to post-(un)install steps; added devel package for liblinuxsampler;
453          to linuxsampler.spec (RPM)
454        - install necessary development header files for allowing 3rd party
455          applications to link against liblinuxsampler
456        - liblinuxsampler's API documentation can be generated with 'make docs'
457          (Doxygen required)
458        - added benchmark to automatically detect the best triangle LFO
459          implementation (currently either an integer math solution or a
460          di-harmonic approximation), automatic detection can be overriden
461          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
462          configure script argument though (mandatory for cross-compilation)
463        - do not automatically pick optimized gcc flags if the user already
464          provided some on his own (as CXXFLAGS)
465        - added compile time option to disable processing of All-Notes-Off MIDI
466          messages
467        - added compile time options to allow disabling the various audio and
468          MIDI drivers
469        - fixed automatic GCC CPU switch detection on PPC
470          (patch by Ebrahim Mayat)
471    
472      * Gigasampler format engine:
473        - extensive synthesis optimization
474          (reimplementation of EGs and LFO(s), removed synthesis parameter
475          prerendering and the synthesis parameter matrix in general, splitting
476          each audio fragment into subfragments now where each subfragment uses
477          constant pitch and filter coefficients. The volume coefficient is
478          linearly interpolated inside a subfragment, unless
479          --disable-interpolate-volume is set.)
480        - fine tuning of the EG modulation parameters
481        - improved filter cutoff calculation by adding support for the
482          following gig parameters: Cutoff freq (used when no cutoff
483          controller is defined), Control invert, Minimum cutoff, Velocity
484          curve and Velocity range. The keyboard tracking now scales
485          cutoff frequency instead of resonance.
486        - added support for gig parameter Resonance.
487        - fixed bug in sysex handling (patch by Juan Linietsky)
488        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
489          which can be overridden with --enable-global-attenuation
490        - EG fixes: made the length of "attack hold" stage more
491          accurate. Release stage can now start before attack stage
492          ends. Cancel release didn't work when sustain was zero. Attack
493          time now has a minimal value to prevent clicks.
494        - fixed pitch changes larger than one octave
495        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
496        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
497          all modes can be altered via standard GM messages, that is CC5 for
498          altering portamento time, CC65 for enabling / disabling portamento
499          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
500        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
501          parameter) and crossfade
502        - added support for the "attenuation controller threshold" gig
503          parameter
504        - added smoothing of volume changes caused by control change
505          messages
506        - sample loop parameters are now taken from the DimensionRegion
507          instead of the wave chunk
508        - fixed keyswitching for v3 gigs with a number of keyswitch splits
509          not equal to a power of two
510        - reimplementation of the filter algorithm. The new filter is more
511          accurate and supports all gig filter types, including bandreject
512          and lowpass turbo.
513        - real support for 24 bit samples - samples are not truncated to
514          16 bits anymore
515        - support for aftertouch (channel pressure, not polyphonic
516          aftertouch)
517        - LFO1 behaviour fixed (dampening from max volume instead of
518          amplifying from 0)
519    
520      * LSCP server:
521        - fixed application exit on broken pipe error (fixes bug #20)
522        - fixed the notification messages delay due to lack of
523          network activity (fixes bug #26)
524        - fixed parser bug which occured on space(s) within device parameters
525          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
526    
527      * audio driver:
528        - added aRts audio output driver (by no means RT safe)
529    
530      * MIDI driver:
531        - fixed legacy sysex code which caused dispatching of MIDI SysEx
532          messages several times instead of once
533        - API extension for MIDI drivers which already supply exact time stamps
534          for events (i.e. for offline rendering based MIDI drivers)
535        - added checks for bad MIDI data
536    
537      * linuxsampler application:
538        - show available sampler engine types on startup
539    
540      * general changes:
541        - support for muting sampler channels and solo mode of the same, two new
542          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
543          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
544          introduced for this, the behavior is the same like on a mixer console
545          (patch by Grigor Iliev, a bit adjusted). Also added configure option
546          --enable-process-muted-channels which can be used to enable the
547          processing of muted channels.
548        - support for sostenuto pedal
549        - support for monitoring the total number of active voices
550          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
551          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
552        - fixed some memory management errors
553        - fixed some concurrency problems that could lead to crashes when
554          LSCP commands were executed
555        - fixed crash when instrument loading failed previously on the same
556          sampler channel (fixes bug #36)
557    
558    Version 0.3.3 (15 July 2005)
559    
560      * packaging changes:
561        - fixed compilation with gcc 4.0
562    
563      * Gigasampler format engine:
564        - LFO preprocessing was performed even though the respective LFO was
565          disabled by the instrument patch (minor efficiency fix)
566        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
567          for volume ramp downs in the same fragment (needed for current voice
568          stealing implementation) then simply inform the user with a warning
569          about possible click sounds and reduce the volume ramp down
570          appropriately instead of cancelling the audio device connection
571    
572    Version 0.3.2 (24 June 2005)
573    
574    * packaging changes:    * packaging changes:
575      - updated autotools build files to compile on OS X      - updated autotools build files to compile on OS X
576        (conditional compilation of CoreMIDI and MidiShare drivers)        (conditional compilation of CoreMIDI and MidiShare drivers)
577    * support for the gig parameters for "release velocity response"      - hand-crafted assembly optimization code can be disabled with
578      curves        './configure --disable-asm' (definitely not recommended)
579    * fine tuning of the EGADSR envelope      - fixed 'make dist' rule to include all necessary files
580        - require automake (>= 1.5) for 'make -f Makefile.cvs'
581          (due to 'dist-bzip2' automake option)
582    
583      * Gigasampler format engine:
584        - support for the gig parameters for "release velocity response" curves
585        - fine tuning of the EGADSR envelope
586        - volume of release triggered samples now depends on note-on velocity,
587          note length and gig parameter "release trigger decay" instead of
588          note-off velocity.
589        - revised voice stealing
590          (fixes crash and endless loop caused by voice stealing)
591        - don't reset scale tuning on instrument or audio output device change
592        - handle key group conflicts right at the beginning of each fragment
593          instead of when the respective voice is actually launched
594          (fixes undefined behavior if stolen voices belonged to a key group -
595          this case was followed by a "killed voice survived" error message)
596        - fixed minor issue with null/silence samples
597          (those stole voices even though they don't need a voice at all which
598          resulted in "voice stealing didn't work out" messages)
599        - don't reset volume, pan, pitch and MIDI controller values on
600          instrument or audio output device change
601    
602      * LSCP server:
603        - fixed some crashes (patch by Grigor Iliev, fixes #19)
604        - fixed LSCP event "CHANNEL_INFO" notification
605          (e.g. did not notify on volume changes or MIDI program change events)
606    
607      * linuxsampler application:
608        - added command line parameters --lscp-addr and --lscp-port to override
609          default IP address and port of LSCP server
610    
611  Version 0.3.1 (24 May 2005)  Version 0.3.1 (24 May 2005)
