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

559        - fixed minor issue with null/silence samples
560          (those stole voices even though they don't need a voice at all which
561          resulted in "voice stealing didn't work out" messages)
562        - don't reset volume, pan, pitch and MIDI controller values on
563          instrument or audio output device change
