# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * SFZ format engine:
4        - added support for <global>, <master> and #define (patch by Alby M)
5        - Removed code duplication in SFZ file loading code.
6        - Added support for sfz extension opcode 'script' which may be used to
7          load real-time instrument script file (NKSP script language).
8        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9    
10      * Gigasampler format engine:
11        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
12          cutoff settings.
13    
14      * general changes:
15        - fixed printf type errors (mostly in debug messages)
16        - use unique_ptr instead of auto_ptr when building with C++11
17        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
18          allowing to sort data efficiently in real-time safe manner.
19        - RTList class: added methods for moving/inserting elements to arbitrary
20          position within a list.
21        - RTList class: added method fromPtr() for creating an Iterator object from
22          a raw element pointer.
23        - Attempt to partly fix resetting engine channels vs. resetting engine, an
24          overall cleanup of the Reset*(), ConnectAudioDevice(),
25          DisconnectAudioDevice() API methods would still be desirable though,
26          because the current situation is still inconsistent and error prone.
27        - Active voices are now internally grouped to "Note" objects, instead of
28          being directly assigned to a keyboard key. This allows more fine graded
29          processing of voices, which is i.e. required for certain instrument
30          script features.
31        - Fix: Release trigger voices were not spawned on sustain pedal up
32          (CC #64) events.
33        - Fix: Release trigger voices can now also distinguish correctly between
34          note-off and sustain pedal up events.
35        - All engines: Increased ramp speed of volume smoother and pan smoother
36          (while slow rate of crossfade smoother is preserved) to allow quick
37          volume and pan changes by instrument scripts for instance.
38        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
39          properly and thus were ignored for certain uses.
40        - Added new C++ API method
41          VirtualMidiDevice::SendChannelPressureToSampler().
42        - windows, 32-bit: fixed potential crashes by making sure the stack in
43          sub threads is 16-byte aligned
44        - fixed numerous compiler warnings
45    
46      * packaging changes:
47        - removed unnecessary dependency to libuuid
48          (originated by libgig's usage of it)
49        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
50          auto detect whether it (sh/c)ould output its messages in color.
51    
52      * Real-time instrument scripts:
53        - Implemented scheduler for delayed MIDI events and for suspended scripts.
54        - Built-in script function "wait()": implemented support for function's
55          "duration-us" argument, thus scripts using this function are now
56          correctly resumed after the requested amount of microseconds.
57        - Built-in script function "play_note()": implemented support for
58          function's "duration-us" argument, thus notes triggered with this
59          argument are now correctly released after the requested amount of
60          microseconds.
61        - Fix: script events were not cleared when engine channel was reset,
62          potentially causing undefined behavior.
63        - Fixed crash which happened when trying to reference an undeclared
64          variable.
65        - Built-in script function "play_note()": Added support for passing
66          special value -1 for "duration-us" argument, which will cause the
67          triggered note to be released once the original note was released.
68        - Instrument script classes now exported with the liblinuxsampler C++ API.
69        - Added new API method ScriptVM::syntaxHighlighting() which provides
70          a convenient syntax highlighting backend for external instrument
71          script editor applications.
72        - Added new C++ API class "ScriptVMFactory".
73        - Extended parser issues to provide not only first line and first
74          column, but also last line and last column of issue (thus marking
75          the precise span of the issue within the source code).
76        - Reload script automatically after being modified by an instrument
77          editor.
78        - NKSP language grammar correction: allow empty event handler bodies
79          like "on note end on".
80        - Implemented built-in script function "change_vol()".
81        - Implemented built-in script function "change_tune()".
82        - Implemented built-in script function "change_pan()".
83        - Implemented built-in script function "change_cutoff()".
84        - Implemented built-in script function "change_reso()".
85        - Implemented built-in script function "event_status()".
86        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
87          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
88          "event_status()" function.
89        - NKSP language: Added support for bitwise operators ".or.", ".and."
90          and ".not.".
91        - NKSP language scanner: Fixed IDs matching to require at least one
92          character (i.e. when matching function names or variable names).
93        - NKSP language scanner: disabled unusued rules.
94        - Fixed behavior of play_note() and note_off() functions which must
95          be distinguished engine internally from "real" MIDI note on/off
96          events in order to avoid misbehaviors like hanging notes.
97        - Implemented built-in script variable "$KSP_TIMER".
98        - Implemented built-in script variable "$NKSP_REAL_TIMER".
99        - Implemented built-in script variable "$NKSP_PERF_TIMER".
100        - Implemented built-in script variable "$ENGINE_UPTIME".
101        - Implemented built-in script function "inc()".
102        - Implemented built-in script function "dec()".
103        - NKSP language fix: division expressions were evaluated too often.
104        - NKSP language fix: string concatenation operator was right
105          associative instead of left (to right).
106        - NKSP language correction: allow empty statements in entire language
107          (i.e. "if end if").
108        - Implemented built-in script function "stop_wait()".
109        - Implemented built-in script variable "$NI_CALLBACK_ID".
110        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
111        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
112        - Added support for read-only built-in variables (respectively
113          handled by the script parser).
114        - Added built-in script constant "$NI_CB_TYPE_INIT".
115        - Added built-in script constant "$NI_CB_TYPE_NOTE".
116        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
117        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
118        - NKSP Language: Added support for user defined script functions.
119        - Implemented built-in script function "change_attack()".
120        - Implemented built-in script function "change_decay()".
121        - Implemented built-in script function "change_release()".
122        - Fixed all change_*() built-in script functions to apply their
123          synthesis parameter changes immediately in case the respective note
124          was triggered at the same time, instead of scheduling the parameter
125          change, especially because it would cause some parameter types's
126          changes either to be ramped (i.e. change_vol()) or other types even
127          to have not effect at all (i.e. change_attack()).
128        - Implemented built-in script function "sh_left()".
129        - Implemented built-in script function "sh_right()".
130        - Implemented built-in script function "min()".
131        - Implemented built-in script function "max()".
132        - NKSP Fix: "init" event handler was not always executed when a script
133          was loaded.
134        - NKSP built-in wait() script function: abort script execution if
135          a negative or zero wait time was passed as argument (since this is
136          a common indication of a bug either of the script or even of the
137          engine, which could lead to RT instability or even worse).
138        - ScriptVM: Implemented automatic suspension of RT safety
139          threatening scripts.
140        - Provide more user friendly error messages on syntax errors.
141        - Fixed NKSP parser warning "Not a statement" when assigning an
142          initializer list to an array variable.
143        - Implemented built-in script array variable "%ALL_EVENTS".
144        - Implemented built-in script function "in_range()".
145    
146      * Instruments DB:
147        - Fixed memory access bug of general DB access code which lead to
148          undefined behavior.
149        - Cleanup of instruments DB file creation and opening code.
150        - The instrument DB path of linuxsampler's --create-instruments-db argument
151          is now optional, if it is missing, then a default location is used.
152        - Added support for scanning SFZ (.sfz) files.
153        - Added support for scanning Sound Font (.sf2) files.
154    
155    Version 2.0.0 (15 July 2015)

159        - Mac OS X: support the new dir for Core Audio SDK
160        - Mac OS X: fixed building outside source directory
161        - made sure all source files for hostplugins are included when
162          doing "make dist"
163        - removed empty directories left from the cvs to svn migration
164        - fixed compilation with gcc 4.6.1
165        - another "make dist" fix, for the LV2 plugin
166        - made --enable-pthread-testcancel default on Mac OS X
167        - minor Makefile fix for building lscpparser when build and source
168          directories are separate
169        - Mac OS X: made it possible to specify plugin installation dir to
170          configure
171        - Mac OS X: Makefile fix for the install-strip target
172        - fixed compilation with gcc 4.7
173        - fixed configure script error with old autoconf versions
174        - lsatomic.h: use gcc provided atomic functions if building with
175          gcc 4.7 and C++11
176        - modernized configure script
177        - fixed linkage error when building with
178          LDFLAGS="-Wl,--no-undefined" (#190)

187          on the process's main thread
188        - fixed build error on newer MinGW
189        - support building with older jack versions
190        - support building with spaces in vst sdk path
191        - enabled automake 'subdir-objects' option and moved external
192          source references (vst, au, asio) from makefiles to cpp files,
193          in order to get rid of warnings from automake 1.14
194    
195      * general changes:
196        - Refactoring: moved the independent code from
197          the Gigasampler format engine to base classes
198        - command line option '--profile' is currently disabled, since the
199          respective profiling code is currently broken
200        - Introduced support for optional environment variable
201          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
202          where the sampler shall look for instrument editor plugins
203          (patch by Luis Garrido, slightly modified).
204        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
205        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
206        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
207          note (in this implementation of the sampler its simply hard routed to
208          the 1st effect send of the sampler channel, no matter what the actual
209          effect type is)
210        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
211          note (in this implementation of the sampler its simply hard routed to
212          the 2nd effect send of the sampler channel, no matter what the actual
213          effect type is)
214        - implemented support for internal LADSPA effects
215        - raised limit of program change queue from 100 to 512
216          (as suggested by Alex Stone)
217        - implemented sine LFO, pulse LFO and saw LFO
218        - experimental support for per voice equalization
219        - added command line option --exec-after-init
220        - Introduced new C++ API method:
221          EngineChannel::InstrumentFileName(int index)
222          allowing to retrieve the whole list of files used for the loaded
223          instrument on an engine channel (a.k.a. part). Some GigaStudio
224          instruments for example are splitted over several files like
225          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
226        - Added new C++ API method Sampler::GetGlobalMaxVoices().
227        - Added new C++ API method Sampler::GetGlobalMaxStreams().
228        - Added new C++ API method Sampler::SetGlobalMaxVoices().
229        - Added new C++ API method Sampler::SetGlobalMaxStreams().
230        - Various "const" and "restrict" optimizations.
231        - all engines: add pan CC value to instrument pan parameter before
232          applying panning, instead of using two separate pan functions in
233          series (#182)
234        - added a lock guard class for exception safe mutex handling and
235          used it everywhere appropriate
236        - Immediately apply scale tuning changes to active voices.
237        - Exposed scale tuning to C++ API (along to the already existing standard
238          SysEx way).
239        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
240          and broken for ppc64. (Seq_cst loads and stores are actually not
241          used in LS, so the bug wasn't noticable.)
242        - lsatomic.h: added ARMv7 support
243        - Added support for multiple MIDI input ports per sampler channel (and
244          added various new C++ methods for this new feature / design change, old
245          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
246          as deprecated but are still there and should provide full behavior
247          backward compatibility).
248        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
249          unsafe and caused compilation error with clang 2.x).
250        - Bugfix: only process the latest MIDI program change event.
251        - Introducing the LSCP shell, which provides convenient control of the
252          sampler from the command line by providing LSCP aware features.
253        - VirtualMidiDevice: Added support for program change.
254        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
255        - VirtualMidiDevice: Added support for pitch bend.
256        - Aftertouch: extended API to explicitly handle channel pressure and
257          polyphonic key pressure events (so far polyphonic pressure was not
258          supported at all, and channel pressure was rerouted as CC128 but not
259          used so far).
260        - Added initial support for real-time instrument scripts. The script VM
261          code is shared by all sampler engine implemementations, however only the
262          gig file format currently provides support for storing instrument scripts
263          (as LinuxSampler extension to the original GigaStudio 4 format).
264    
265      * Gigasampler format engine:
266        - implemented the "round robin keyboard" dimension
267        - fixed round robin and random dimensions for cases when number of
268          dimension zones is not a power of two
269        - made round robin use a counter for each region instead of each
270          key
271        - bugfix: pitch LFO controller "internal+aftertouch" was broken
272        - bugfix: filter keyboard tracking was broken
273        - filter performance fix (an unnecessary copy was made of the
274          filter parameters in each sub fragment)
275        - handle special case when pan parameter in gig file has max or
276          min value
277        - Exclusive Groups: don't ever stop voices of the same note,
278          doesn't sound naturally with a drumkit
279        - fixed EG1 modulation when attack or release is zero
280        - Fixed support for 'aftertouch' attenuation controller.
281        - Fixed crash that happened with velocity split sounds under certain
282          conditions (see also previous commit on libgig).
283        - fixed behaviour of filter LFO
284    
285      * SFZ format engine:
286        - Initial implementation (not usable yet)
287        - added support for v2 multiple stage envelope generators
288        - added a fine-tuned v1 envelope generator instead of using the
289          one from the gig engine
290        - fixed memory leak and memory handling errors
291        - added support for trigger=first, trigger=legato and sw_previous
292        - allow non-numerical key values ("C#4" for example)
293        - "key" opcode now sets pitch_keycenter too
294        - fixed error when unloading instrument with same sample used by
295          multiple regions
296        - added some opcode aliases, like loopmode for loop_mode, to be
297          more compatible
298        - added support for trigger=release and rt_decay
299        - added support for off_mode=normal
300        - added support for random, seq_position, seq_length and volume
301        - added v1 LFO opcodes to parser (no support in engine yet)
302        - added support for amp_veltrack and amp_velcurve_N
303        - fine-tuned the default velocity curve
304        - added support for transpose
305        - fixed crash when using sw_down/up
306        - improved logic for sw_lokey/hikey/up/down/last
307        - added more v1 aliases to parser
308        - reduced memory usage for sfz data
309        - RT-safeness: avoid malloc in audio thread
310        - fixed a bug that could cause voice stealing to fail
311        - optimized sample lookup
312        - improved support for exclusive groups (group, off_by and
313          off_mode)
314        - added support for controller triggered regions (on_locc/on_hicc)
315        - added support for loop_mode=one_shot
316        - fixed playback of 16 bit wav files on big endian CPUs
317        - added support for Ogg Vorbis sample files
318        - use loop markers from sample file if loop_start and loop_end are
319          not set in sfz file
320        - implemeted filters. Filter types: lowpass, bandpass, bandreject
321          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
322          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
323          cutoff_cc, cutoff_chanaft.
324        - bugfix: zero ampeg_sustain didn't work
325        - added support for velocity effect on amplifier envelope time
326          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
327          ampeg_vel2release)
328        - added support for EG hold (ampeg_hold)
329        - added support for sample offset (offset)

462        - VST bugfix: If the host called resume() before and after
463          changing sample rate or block size, the number of channels was
464          incorrectly set to two. This caused silence in Cubase 5.
465        - save engine type (gig, sfz or sf2) in plugin state
466        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
467          64 bit Windows

506          there is no reason for this limit
507        - MME: fixed memory handling bug found with cppcheck
508        - MME: removed compiler warning
509        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
510          which allows to retrieve the list of CoreMIDI clients / ports and to connect
511          to them a la JACK, via the usual sampler APIs
512        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled

522        - MME bugfix: driver wasn't closed properly
523        - CoreMIDI: automatically connect to all input sources by default (driver
524          parameter "AUTO_BIND").
525        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
526        - CoreMIDI: fixed minor memory leak
527    
528      * audio driver:
529        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
530        - JACK audio: react on sample rate changes.

533          RT context.
534        - ASIO driver: removed compiler warnings
535        - CoreAudio: fixed minor error handling bug
536        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

588        - Added support for moving cursor left/right with arrow keys.
589        - Added support for built-in LSCP reference documentation, which will
590          automatically show the relevant LSCP reference section on screen as soon

653        - bugfix: calling SET VOICES (which Fantasia does on start and
654          refresh) could cause instruments to be unloaded
655        - Mac OS X: fixed name collision of enum in EffectControl and
656          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
657        - Mac OS X: fixed hanging threads

660        - Fixed possible crashes due to corrupted MIDI/audio device list
661          after MIDI/audio device creation failure
662        - When creating MIDI instrument map entries with "PERSISTENT" type, the
663          instruments were uselessly precached with zero samples, however it still
664          took the full preloading time and on 1st program change the respective
665          instrument was completely reloaded again.
666        - fixed handling of rapid bank select and program change messages
667          sent to the same sampler channel (patch from the Open Octave

681          introduced in previous fix)
682        - fixed crash when a channel received a program change while
683          playing a note in a key group
684        - fixed erroneous error message piping in VoiceBase.h
685          (labelled "Disk stream not available in time")
686        - Update effects on sample rate & period size changes (to avoid
687          crashes and noise on such transitions).
688        - ignore missing LADSPA paths without ignoring valid LADSPA paths
689          (fixes #208)
690        - Fixed bug in LSCP grammar definition which caused a statement like
691          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
692          practically irrelevant, however it caused problems with the new LSCP
693          shell's auto completion feature).
694        - Fixed MIDI program change messages being ignored if quickly executed
695          after each other (fixes #231).
696    
697    Version 1.0.0 (31 July 2009)
698    
699    * packaging changes:    * packaging changes:
700        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
701          causing e.g. the libgig test to fail when
702          "./configure --disable-jack-driver" was used
703          (patch by Alexis Ballier)
704        - fixed compilation with gcc 4.3
705        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
706        - fixed configure so it detects x86_64 (#107)
707        - fixes for building with newer MinGW versions
708        - fix for building with bison 2.4 (#111)
709        - fixed building with libgig installed in a non-standard directory
710        - minor fix in configure for mmsystem.h detection on MinGW
711        - Windows: look for editor plugins and Fantasia using base
712          directory of liblinuxsampler dll (look in the same directory and one
713          directory above)
714        - configure script fix: removed unconditional use of SSE
715        - fixed building with sqlite installed in a non-standard directory
716        - when cross-compiling, don't try to create instruments.db
717        - fix for new mingw-w64 version, which has usleep
718    
719      * general changes:
720        - bugfix: on some POSIX systems instrument editor plugins refused to
721          load as we used a non-portable Linux specific struct field
722          (fixes bug #70, patch by Ronald Baljeu)
723        - fixed endless loop which occured when loading an instrument editor
724          plugin DLL on Windows systems failed
725        - fixed memory leaks that occurred when liblinuxsampler was unloaded
726        - optimized the SynchronizedConfig class so it doesn't wait
727          unnecessarily long after an update
728        - added support for notifying instrument editors on note-on / note-off
729          events (e.g. to highlight the pressed keys on the virtual keyboard
730          of gigedit)
731        - added support for triggering notes by instrument editors (see above)
732        - be verbose on DLL load errors (on Linux)
733        - fixed di-harmonic triangle LFO implementation (this LFO implementation
734          is only used by very few systems, most pick the int math
735          implementation, which is usually faster)
736        - fixes for audio drivers with varying buffer sizes
737        - experimental support for running LinuxSampler as a DSSI, LV2 and
738          VST plugin
739        - notification events for stream/voice count statistics are now sent
740          only when there are actual changes
741        - added memory ordering constraints to improve stability on
742          multi-core and multi-cpu systems
743        - maximum voices and disk streams can now be altered at runtime
744        - fixed CPU feature detection on x86_64 (maybe fixes #108)
745        - automatic stacktrace mechanism is now turned off by default and can
746          be switched on by command line option "--stacktrace" (the automatic
747          stacktrace mechanism seems to be broken on most systems at the moment)
748        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
749          a pointer to the launched InstrumentEditor object
750        - added optional 3rd party user data parameter for following
751          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
752          InstrumentEditor::Launch(),
753          InstrumentManager::LaunchInstrumentEditor()
754        - theoretical fix: made SynchronizedConfig follow C++0x memory
755          model more strictly
756        - fixes for using large audio device buffers
757        - Windows: add the installation directory to the DLL search path
758          when loading an editor plugin (solves problems with VST and
759          gigedit on systems with other GTK versions installed)
760        - updated linuxsampler man page
761    
762      * audio driver:
763        - removed the nonsense audio channel constraint (which was hard coded to
764          max. 100 audio channels) for most audio drivers
765        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
766          opposed to the LSCP specs
767        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
768          reflected the wrong value
769        - fixed a memory management bug in ASIO driver
770        - Makefile fix: JACK_CFLAGS wasn't used
771        - JACK: use jack_client_open instead of the deprecated
772          jack_client_new
773        - added (experimental) CoreAudio driver
774        - applied old fixes to the ASIO driver that were included in the
775          previous binary release but accidentally never committed to CVS
776          (fixes #117)
777        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
778          win64)
779        - VST: added support for sample rate and buffer size changes
780        - VST: close editor (Fantasia) when the VST is removed
781        - VST: avoid opening Fantasia more than once for each VST instance
782        - VST: export main function as "main" on Linux too (fix for
783          energyXT)
784        - VST: changed number of output channels from one stereo to 16
785          stereo
786        - added channel routing, fxsends and midi maps to the settings
787          stored in the plugin state
788        - performance optimization of AudioChannel::MixTo() and
789          AudioChannel::CopyTo() methods using GCC vector exensions
790          (if available)
791        - ASIO fixes: avoid initializing the device twice, avoid throwing
792          exception when getting parameters from a disconnected device
793    
794      * MIDI driver:
795        - added JACK MIDI driver
796        - dispatch bank select as ordinary CC as well, the user might seriously
797          want to (mis)use it for some purpose ("fixed" in all current MIDI
798          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
799        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
800          CoreMidi or AU
801        - fixed mingw-w64 compilation error in MME driver
802        - made program change handling in MIDI thread real-time safe by
803          moving the logic to a non-RT thread
804        - fixed minor memory leak in ALSA driver
805    
806      * instruments database:
807        - avoid time consuming samples scanning when adding instruments
808          to the instruments database
809        - added support for handling lost files in the instruments database
810        - Implemented option for adding instruments in separate directories
811          in the instruments database
812          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
813        - work-around for missing fnmatch function on Windows to make
814          instrument database compilable
815        - added instrument database support on Windows
816          works with both standalone mode and VST plugin.
817          the instruments DB file is located in
818          %USERPROFILE%\.linuxsampler\instruments.db which allows different
819          databases for each windows user
820          if no DB is present it automatically creates the .linuxsampler subdir
821          and then creates an empty DB
822        - fixed recursive import, which was broken on Windows
823    
824      * Gigasampler format engine:
825        - fixed a memory leak that could happen when a channel was deleted
826          while notes were playing
827        - made it possible to load an instrument even if the audio thread
828          isn't running
829        - added partial support for the "Controller Triggered" MIDI rule,
830          enough for piano gigs with pedal noise samples
831        - minor fix: only mark FX sends as being modified if really the
832          respective FX send MIDI controller was used
833        - added support for GM global device volume SysEx message
834          (can be selected at compile time to either apply globally to the
835          whole sampler [default] or only to the sampler channels that are
836          connected to the respective MIDI input port the SysEx message arrived
837          on)
838        - bugfix: notes triggered at position 0 in the audio buffer were
839          sometimes wrongly killed in the same buffer, causing no sound to
840          be played
841        - added support for chromatic / drumkit mode Roland GS Sysex message
842          which is usally used to switch a part between chromatic sounds and
843          drumkit sounds (as opposed to their common default setting of MIDI
844          part 10 being a drumkit part and all other ones chromatic parts), in
845          LS however one can switch between the first 16 MIDI instrument maps
846          defined for the sampler
847        - made it possible to create multiple sample channels even if the
848          audio thread isn't running
849        - fixed crash when removing channel with active voices (#116)
850        - bugfix: on sample reference changes (instrument editor), only
851          un-cache the respective sample if it's really not used by any
852          sampler engine anymore
853        - re-cache samples in case they were changed by an instrument editor,
854          e.g. when a sample was added while playing (#82)
855        - fixed hanging notes which occured when note-off event had the exact
856          same time stamp as the voice's note-on event and occured both in the
857          same audio fragment cycle (fixes bug #112)
858        - added support for the "fine tune" and "pitch bend range"
859          instrument-level gig parameters
860        - fixed minor artifacts in pitch bend handling
861        - added support for GS Reset SysEx message
862        - allow gig files to use unlimited downward pitch shifting
863        - added a limit check for upward pitch shifting
864        - bugfix: sometimes, when playing a note twice fast, the second
865          note was silent
866        - fixed crash happening when a pitch bend event arrived at the
867          same time a new instrument was loading
868    
869      * LSCP server:
870        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
871          react on MIDI data arriving on certain sampler channels (so far only
872          Note-On and Note-Off events are sent via this LSCP event)
873        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
874          react on MIDI data arriving on certain MIDI input devices (so far only
875          Note-On and Note-Off events are sent via this LSCP event)
876        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
877          SET DB_INSTRUMENT FILE_PATH
878        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
879          frontends to send MIDI messages to specific sampler channel
880        - added two additional fields to GET FILE INSTRUMENT INFO command -
881          KEY_BINDINGS and KEYSWITCH_BINDINGS
882        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
883          was incorrect
884        - Optimized the retrieval of the MIDI instrument mappings
885        - added new LSCP command "SET VOICES" to globally alter the maximum
886          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
887          be triggered respectively
888        - added new LSCP command "SET STREAMS" to globally alter the maximum
889          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
890          which will be triggered respectively
891        - bugfix: retry if "select" returns EINTR (this fixes a crash when
892          a gigedit file dialog is opened)
893        - close all connections when LSCPServer is deleted
894        - hard close of all sockets on exit
895        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
896          driver
897    
898      * Bug fixes:
899        - fixed a crash which occurs when removing a sampler channel waiting
900          to start instrument loading after another channel
901        - fixed a crash which occurs when removing a sampler channel with
902          instrument loading in progress (bug #113)
903        - fixed termination caused by uncaught exception when adding MIDI
904          instrument with PERSISTENT load mode
905        - fixed possible iterator invalidations when resetting the sampler
906        - fixed memory leaks when issuing the following LSCP commands:
907          GET AUDIO_OUTPUT_DRIVER INFO
908          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
909          GET MIDI_INPUT_DRIVER INFO
910          GET MIDI_INPUT_DRIVER_PARAMETER INFO
911        - fixed possible compilation error when sqlite is not present
912        - fixed orphaned pointers when setting maximum voices limit (bug #118)
913        - fixed crash when changing the audio output device of a sampler
914          channel with loaded instrument and start playing notes
915        - fixed endless loop in Engine::SuspendAll() (bug #120)
916        - fixed a low-level atomic load function that was broken on 64-bit
917          PowerPC, which probably could cause crashes on that platform
918        - fixed a memory management error which could cause a crash when a
919          plugin was unloaded
920        - bugfix: two private structs had the same name, which could cause
921          problems if the linker chose the wrong constructor
922        - fixed low-level ConditionServer usage bug that caused lockups on
923          Windows
924    
925    
926    Version 0.5.1 (6 December 2007)
927    
928      * packaging changes:
929        - added autoconf checks for pthread library
930        - added autoconf check for pthread bug found on certain NPTL-enabled
931          glibc versions (see Gentoo bug report #194076)
932        - added autoconf checks for MS Windows
933    
934      * general changes:
935        - bugfix: the thread used by an editor plugin didn't die when the
936          editor closed
937        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
938          out all the space. operator--() did not apply size_mask after
939          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
940          order to avoid problems with the _NonVolatileReader functions.
941        - bugfix: Stream.h: added a missing divide by BytesPerSample in
942          GetWriteSpace(). Since this function is currently only used in
943          the stream's qsort() compare function, it didn't trigger any
944          bugs.
945        - Resampler.h, Synthesizer.h: cubic interpolation now works in
946          24bit mode too. Faster method to read 24bit words on little
947          endian machines (x86): replaced 3 byte reads + shifts with a 1
948          unaligned 32bit read and shift
949        - experimental support for MS Windows (MIDI input via MME, AUDIO
950          output via ASIO)
951        - made handling of SIGINT signal (Ctrl-C) a bit more robust
952        - support for monitoring the total number of active disk streams
953          (new LSCP commands: GET TOTAL_STREAM_COUNT,
954          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
955    
956      * AUDIO driver:
957        - added Windows ASIO low latency audio driver
958    
959      * MIDI driver:
960        - added MME Windows MIDI driver
961    
962      * LSCP server:
963        - added support for Windows style path / filenames, however with
964          forward slash path separators instead of backslash
965          (i.e. "C:/foo/bar.gig")
966        - allow naughty liblscp to send non-string device parameters within
967          apostrophes as well
968        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
969          "LIST FILE INSTRUMENTS <file>" and
970          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
971          about an arbitrary instrument file on the system where the sampler is
972          running on
973    
974    Version 0.5.0 (15 October 2007)
975    
976      * packaging changes:
977        - config.h is not going to be installed along with liblinuxsampler's
978          API header files anymore
979        - only the API relevant header (and source) files will be exported to
980          the Doxygen API documentation (explicitly listed in Doxyfile.in)
981        - added completely new XCode project files for Mac OSX which is now
982          capable to execute our autoconf environment, thus no need anymore
983          to maintain the compile time configuration file (osx/version.h) for
984          OSX manually (patch by Toshi Nagata)
985        - fixed buggy boolean --enable-foo / --disable-foo configure script
986          parameters
987        - global.h now only covers global definitions that are needed for the
988          C++ API header files, all implementation internal global definitions
989          are now in global_private.h
990        - atomic.h is not exposed to the C++ API anymore
991        - no need to include config.h anymore for using LS's API header files
992        - fixed warnings in API doc generation
993    
994      * general changes:
995        - replaced the old, confusing MIDI program change mechanism by a
996          flexible MIDI instrument mapper which allows to map arbitrary
997          (MIDI bank, MIDI program) pairs with arbitrary
998          (engine type, instrument file, file index) triplets which will be
999          loaded on the respective channel when such MIDI program change
1000          messages arrive, beside that, each entry allows to define a life-time
1001          strategy for the instrument, so the user can define whether the
1002          instrument should i.e. be permanently loaded (to be able to switch
1003          quickly among sounds) or i.e. loaded just on demand when the
1004          respective program change arrives (to safe RAM space), as well as a
1005          global volume factor for each entry, so the user can adjust the volume
1006          dynamic of his mapped instrument collection without having to modify
1007          the instrument files, also one can manage arbitrary amount of such
1008          MIDI instrument maps and assign each sampler channel individually
1009          a certain map, so that i.e. separation of normal instruments and
1010          drumkits is possible
1011        - new notification events for tracking changes to audio/MIDI devices,
1012          MIDI instrument maps, MIDI instruments, FX sends, global volume.
1013        - sampler was limited to load max. 200 instruments in the background
1014          due to a constant size RingBuffer FIFO which is now replaced by a
1015          dynamic (unlimited) size std::list FIFO
1016        - added FX sends, these allow to route audio signals to arbitrary audio
1017          output channels for being processed by external effect processors
1018          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1019          controllers
1020        - global (sampler wide) volume can now be controlled at runtime
1021        - Implemented new, improved notification system
1022        - fixed compilation errors regarding OSX
1023          (patch by Toshi Nagata)
1024        - implemented instruments database
1025        - added support for escape sequences to the instruments database
1026        - added highly experimental support for on-the-fly instrument editing
1027          within the sampler's process (by using instrument editor plugins),
1028          you'll notice the new "Registered instrument editors:" message on
1029          startup, added a new LSCP command:
1030          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1031          to spawn a matching instrument editor for the instrument on the
1032          given sampler channel, the plugin path can be overridden at compile
1033          time with ./configure --enable-plugin-dir=/some/dir
1034        - added experimental code for synchronizing instrument editors hosted
1035          in the sampler's process to safely edit instruments while playing
1036          without a crash (hopefully) by either suspending single regions
1037          wherever possible or if unavoidable whole engine(s)
1038        - fixed several issues in fundamental "Thread" class: set scheduling
1039          policy and priority on thread level, set a minimum stack size for
1040          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1041          threads simply inherited properties of starting thread instead of
1042          setting their own policy and priority
1043        - minor fix in our automatic stack trace mechanism on crashes, the
1044          main process did not wait for the stack trace process to finish
1045          its output
1046        - fixed some minor memory leaks
1047        - reenabled assembly features support, at the moment only for
1048          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1049        - minor assembly fix in x86 features detection (don't use the PIC
1050          register, to avoid relocations in the text segment at runtime)
1051        - POSIX callback functions of Thread.h are hidden
1052    
1053      * MIDI driver:
1054        - dispatch bank select (MSB and LSB) messages
1055    
1056      * audio driver:
1057        - the ALSA audio output driver parameters now reflect the correct
1058          parameter value ranges for the respective selected sound card
1059          (patch by Till Wimmer, a bit fixed and extended)
1060    
1061      * Gigasampler format engine:
1062        - if a filter is used and EG2 finishes before EG1, let the voice
1063          die when EG2 has finished (this fixes a problem with clicks and
1064          voice starvation for some gigs)
1065        - playback is no longer disabled during instrument loading
1066        - all notes playing on a channel that changes its instrument keep
1067          playing with the old instrument until they get a note off
1068          command
1069        - EG fix: a release value of zero could cause noises or crash
1070        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1071        - EG fine tuning: when attack is zero the EG starts at a level
1072          above max sustain level, which means that there is a decay phase
1073          even if sustain is 100%
1074        - more EG fixes: the level could sometimes go below zero and cause
1075          noises or crashes
1076        - minor fix of EGDecay (patch by Toshi Nagata)
1077        - fixed compiler error when --enable-override-filter-type was
1078          supplied to the configure script (fixes #46)
1079        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1080          instead of a fix value
1081        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1082          127 (solo mode) only kill voices if the respective mode really
1083          changed
1084    
1085      * LSCP server:
1086        - fixed compile time error for old Bison versions
1087          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1088        - parser now supports extended ASCII character set
1089          (up to ASCII code 255, i.e. includes now umlauts and accents)
1090        - filename arguments in LSCP commands now allow to use escape
1091          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1092          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1093          code value like \xf2) (fixes bug #24)
1094        - the following LSCP commands now also support escape sequences for at
1095          least one of their text-based parameters (i.e. name, description):
1096          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1097          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1098          "SET DB_INSTRUMENT_DIRECTORY NAME",
1099          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1100          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1101          "FIND DB_INSTRUMENT_DIRECTORIES"
1102        - returns verbose syntax errors (line and column where syntax error
1103          occured, the unexpected character and the actually expected, possible
1104          character(s), the latter only if less than 5 possibilities)
1105        - made sure that LSCP syntax is not affected by gigedit locale
1106          settings
1107        - bugfix regarding strings parameter lists: all comma separated lists
1108          of strings were treated as being one string containing commas
1109          (fixes #57)
1110    
1111      * Bug fixes:
1112        - fixed crash occurring on certain LSCP scripts (Bug 39)
1113        - another thread safety fix for lscp "load engine" and "set
1114          channel audio output device"
1115        - fixed a crash which occurs when reassigning the same engine
1116          on a sampler channel with connected MIDI device
1117        - fixed a crash which occurs when changing the number of ports of a MIDI
1118          device connected to a sampler channel to number less then or equal
1119          to the index of the port to which the sampler channel is connected.
1120        - The previous bindings were not been disconnected when altering
1121          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1122          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1123        - The active stream/voice count statistic was incorrect.
1124        - notification events were not been sent for some sampler
1125          channel changes
1126        - added default min and max values to restrict the number of allowed
1127          audio output channels and MIDI input ports
1128        - the connection to the PCM interface is now closed when destroying
1129          an audio output device
1130        - files with slash in their path or filename could not be loaded
1131    
1132      * test cases:
1133        - updated and fixed (haven't been touched in a while)
1134    
1135    Version 0.4.0 (24 November 2006)
1136    
1137      * packaging changes:
1138        - changed deprecated copyright attribute to license; added ldconfig
1139          to post-(un)install steps; added devel package for liblinuxsampler;
1140          to linuxsampler.spec (RPM)
1141      - install necessary development header files for allowing 3rd party      - install necessary development header files for allowing 3rd party

1152        - added compile time option to disable processing of All-Notes-Off MIDI
1153          messages
1154        - added compile time options to allow disabling the various audio and
1155          MIDI drivers
1156        - fixed automatic GCC CPU switch detection on PPC
1157          (patch by Ebrahim Mayat)
1158    
1159    * Gigasampler format engine:    * Gigasampler format engine:
1160        - extensive synthesis optimization
1161          (reimplementation of EGs and LFO(s), removed synthesis parameter
1162          prerendering and the synthesis parameter matrix in general, splitting
1163          each audio fragment into subfragments now where each subfragment uses
1164          constant pitch and filter coefficients. The volume coefficient is
1165          linearly interpolated inside a subfragment, unless
1166          --disable-interpolate-volume is set.)
1167      - fine tuning of the EG modulation parameters      - fine tuning of the EG modulation parameters
1168        - improved filter cutoff calculation by adding support for the
1169          following gig parameters: Cutoff freq (used when no cutoff
1170          controller is defined), Control invert, Minimum cutoff, Velocity
1171          curve and Velocity range. The keyboard tracking now scales
1172          cutoff frequency instead of resonance.
1173        - added support for gig parameter Resonance.
1174        - fixed bug in sysex handling (patch by Juan Linietsky)
1175        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1176          which can be overridden with --enable-global-attenuation
1177        - EG fixes: made the length of "attack hold" stage more
1178          accurate. Release stage can now start before attack stage
1179          ends. Cancel release didn't work when sustain was zero. Attack
1180          time now has a minimal value to prevent clicks.
1181        - fixed pitch changes larger than one octave
1182        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1183        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1184          all modes can be altered via standard GM messages, that is CC5 for
1185          altering portamento time, CC65 for enabling / disabling portamento
1186          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1187        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1188          parameter) and crossfade
1189        - added support for the "attenuation controller threshold" gig
1190          parameter
1191        - added smoothing of volume changes caused by control change
1192          messages
1193        - sample loop parameters are now taken from the DimensionRegion
1194          instead of the wave chunk
1195        - fixed keyswitching for v3 gigs with a number of keyswitch splits
1196          not equal to a power of two
1197        - reimplementation of the filter algorithm. The new filter is more
1198          accurate and supports all gig filter types, including bandreject
1199          and lowpass turbo.
1200        - real support for 24 bit samples - samples are not truncated to
1201          16 bits anymore
1202        - support for aftertouch (channel pressure, not polyphonic
1203          aftertouch)
1204        - LFO1 behaviour fixed (dampening from max volume instead of
1205          amplifying from 0)
1206    
1207    * LSCP server:    * LSCP server:
1208      - fixed application exit on broken pipe error (fixes bug #20)      - fixed application exit on broken pipe error (fixes bug #20)
1209        - fixed the notification messages delay due to lack of
1210          network activity (fixes bug #26)
1211        - fixed parser bug which occured on space(s) within device parameters
1212          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1213    
1214      * audio driver:
1215        - added aRts audio output driver (by no means RT safe)
1216    
1217      * MIDI driver:
1218        - fixed legacy sysex code which caused dispatching of MIDI SysEx
1219          messages several times instead of once
1220        - API extension for MIDI drivers which already supply exact time stamps
1221          for events (i.e. for offline rendering based MIDI drivers)
1222        - added checks for bad MIDI data
1223    
1224      * linuxsampler application:
1225        - show available sampler engine types on startup
1226    
1227    * general changes:    * general changes:
1228      - support for muting sampler channels and solo mode of the same, two new      - support for muting sampler channels and solo mode of the same, two new

1235        - support for sostenuto pedal
1236        - support for monitoring the total number of active voices
1237          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1238          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1239        - fixed some memory management errors
1240        - fixed some concurrency problems that could lead to crashes when
1241          LSCP commands were executed
1242        - fixed crash when instrument loading failed previously on the same
1243          sampler channel (fixes bug #36)
