# 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        - Fixed unintended volume fade-in of voices under certain conditions.
10    
11      * Gigasampler format engine:
12        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
13          cutoff settings.
14    
15      * general changes:
16        - fixed printf type errors (mostly in debug messages)
17        - use unique_ptr instead of auto_ptr when building with C++11
18        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
19          allowing to sort data efficiently in real-time safe manner.
20        - RTList class: added methods for moving/inserting elements to arbitrary
21          position within a list.
22        - RTList class: added method fromPtr() for creating an Iterator object from
23          a raw element pointer.
24        - Attempt to partly fix resetting engine channels vs. resetting engine, an
25          overall cleanup of the Reset*(), ConnectAudioDevice(),
26          DisconnectAudioDevice() API methods would still be desirable though,
27          because the current situation is still inconsistent and error prone.
28        - Active voices are now internally grouped to "Note" objects, instead of
29          being directly assigned to a keyboard key. This allows more fine graded
30          processing of voices, which is i.e. required for certain instrument
31          script features.
32        - Fix: Release trigger voices were not spawned on sustain pedal up
33          (CC #64) events.
34        - Fix: Release trigger voices can now also distinguish correctly between
35          note-off and sustain pedal up events.
36        - All engines: Increased ramp speed of volume smoother and pan smoother
37          (while slow rate of crossfade smoother is preserved) to allow quick
38          volume and pan changes by instrument scripts for instance.
39        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
40          properly and thus were ignored for certain uses.
41        - Added new C++ API method
42          VirtualMidiDevice::SendChannelPressureToSampler().
43        - windows, 32-bit: fixed potential crashes by making sure the stack in
44          sub threads is 16-byte aligned
45        - fixed numerous compiler warnings
46    
47      * packaging changes:
48        - removed unnecessary dependency to libuuid
49          (originated by libgig's usage of it)
50        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
51          auto detect whether it (sh/c)ould output its messages in color.
52    
53      * Real-time instrument scripts:
54        - Implemented scheduler for delayed MIDI events and for suspended scripts.
55        - Built-in script function "wait()": implemented support for function's
56          "duration-us" argument, thus scripts using this function are now
57          correctly resumed after the requested amount of microseconds.
58        - Built-in script function "play_note()": implemented support for
59          function's "duration-us" argument, thus notes triggered with this
60          argument are now correctly released after the requested amount of
61          microseconds.
62        - Fix: script events were not cleared when engine channel was reset,
63          potentially causing undefined behavior.
64        - Fixed crash which happened when trying to reference an undeclared
65          variable.
66        - Built-in script function "play_note()": Added support for passing
67          special value -1 for "duration-us" argument, which will cause the
68          triggered note to be released once the original note was released.
69        - Instrument script classes now exported with the liblinuxsampler C++ API.
70        - Added new API method ScriptVM::syntaxHighlighting() which provides
71          a convenient syntax highlighting backend for external instrument
72          script editor applications.
73        - Added new C++ API class "ScriptVMFactory".
74        - Extended parser issues to provide not only first line and first
75          column, but also last line and last column of issue (thus marking
76          the precise span of the issue within the source code).
77        - Reload script automatically after being modified by an instrument
78          editor.
79        - NKSP language grammar correction: allow empty event handler bodies
80          like "on note end on".
81        - Implemented built-in script function "change_vol()".
82        - Implemented built-in script function "change_tune()".
83        - Implemented built-in script function "change_pan()".
84        - Implemented built-in script function "change_cutoff()".
85        - Implemented built-in script function "change_reso()".
86        - Implemented built-in script function "event_status()".
87        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
88          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
89          "event_status()" function.
90        - NKSP language: Added support for bitwise operators ".or.", ".and."
91          and ".not.".
92        - NKSP language scanner: Fixed IDs matching to require at least one
93          character (i.e. when matching function names or variable names).
94        - NKSP language scanner: disabled unusued rules.
95        - Fixed behavior of play_note() and note_off() functions which must
96          be distinguished engine internally from "real" MIDI note on/off
97          events in order to avoid misbehaviors like hanging notes.
98        - Implemented built-in script variable "$KSP_TIMER".
99        - Implemented built-in script variable "$NKSP_REAL_TIMER".
100        - Implemented built-in script variable "$NKSP_PERF_TIMER".
101        - Implemented built-in script variable "$ENGINE_UPTIME".
102        - Implemented built-in script function "inc()".
103        - Implemented built-in script function "dec()".
104        - NKSP language fix: division expressions were evaluated too often.
105        - NKSP language fix: string concatenation operator was right
106          associative instead of left (to right).
107        - NKSP language correction: allow empty statements in entire language
108          (i.e. "if end if").
109        - Implemented built-in script function "stop_wait()".
110        - Implemented built-in script variable "$NI_CALLBACK_ID".
111        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
112        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
113        - Added support for read-only built-in variables (respectively
114          handled by the script parser).
115        - Added built-in script constant "$NI_CB_TYPE_INIT".
116        - Added built-in script constant "$NI_CB_TYPE_NOTE".
117        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
118        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
119        - NKSP Language: Added support for user defined script functions.
120        - Implemented built-in script function "change_attack()".
121        - Implemented built-in script function "change_decay()".
122        - Implemented built-in script function "change_release()".
123        - Fixed all change_*() built-in script functions to apply their
124          synthesis parameter changes immediately in case the respective note
125          was triggered at the same time, instead of scheduling the parameter
126          change, especially because it would cause some parameter types's
127          changes either to be ramped (i.e. change_vol()) or other types even
128          to have not effect at all (i.e. change_attack()).
129        - Implemented built-in script function "sh_left()".
130        - Implemented built-in script function "sh_right()".
131        - Implemented built-in script function "min()".
132        - Implemented built-in script function "max()".
133        - NKSP Fix: "init" event handler was not always executed when a script
134          was loaded.
135        - NKSP built-in wait() script function: abort script execution if
136          a negative or zero wait time was passed as argument (since this is
137          a common indication of a bug either of the script or even of the
138          engine, which could lead to RT instability or even worse).
139        - ScriptVM: Implemented automatic suspension of RT safety
140          threatening scripts.
141        - Provide more user friendly error messages on syntax errors.
142        - Fixed NKSP parser warning "Not a statement" when assigning an
143          initializer list to an array variable.
144        - Implemented built-in script array variable "%ALL_EVENTS".
145        - Implemented built-in script function "in_range()".
146    
147      * Instruments DB:
148        - Fixed memory access bug of general DB access code which lead to
149          undefined behavior.
150        - Cleanup of instruments DB file creation and opening code.
151        - The instrument DB path of linuxsampler's --create-instruments-db argument
152          is now optional, if it is missing, then a default location is used.
153        - Added support for scanning SFZ (.sfz) files.
154        - Added support for scanning Sound Font (.sf2) files.
155        - Fixed undefined DB transaction behavior.
156

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

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

466          incorrectly set to two. This caused silence in Cubase 5.
467        - save engine type (gig, sfz or sf2) in plugin state
468        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
469          64 bit Windows

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

524        - MME bugfix: driver wasn't closed properly
525        - CoreMIDI: automatically connect to all input sources by default (driver
526          parameter "AUTO_BIND").
527        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
528        - CoreMIDI: fixed minor memory leak
529    
530      * audio driver:

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

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

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

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

1139      * packaging changes:
1140        - changed deprecated copyright attribute to license; added ldconfig
1141          to post-(un)install steps; added devel package for liblinuxsampler;
1142          to linuxsampler.spec (RPM)
