File size: 69348 byte(s)
* Added support for sfz extension opcode 'script' which may be used to
  load real-time instrument script file (NKSP script language).
* Removed code duplication in SFZ file loading code.
* Bumped version (2.0.0.svn37).

1 persson 2837 Version SVN trunk (?)
2    
3 persson 2856 * SFZ format engine:
4     - added support for <global>, <master> and #define (patch by Alby M)
5 schoenebeck 3082 - 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 persson 2856
9 schoenebeck 3072 * Gigasampler format engine:
10     - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
11     cutoff settings.
12    
13 persson 2837 * general changes:
14     - fixed printf type errors (mostly in debug messages)
15 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
16 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
17     allowing to sort data efficiently in real-time safe manner.
18     - RTList class: added methods for moving/inserting elements to arbitrary
19     position within a list.
20     - RTList class: added method fromPtr() for creating an Iterator object from
21     a raw element pointer.
22     - Attempt to partly fix resetting engine channels vs. resetting engine, an
23     overall cleanup of the Reset*(), ConnectAudioDevice(),
24     DisconnectAudioDevice() API methods would still be desirable though,
25     because the current situation is still inconsistent and error prone.
26 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
27     being directly assigned to a keyboard key. This allows more fine graded
28     processing of voices, which is i.e. required for certain instrument
29     script features.
30 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
31     (CC #64) events.
32     - Fix: Release trigger voices can now also distinguish correctly between
33     note-off and sustain pedal up events.
34 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
35     (while slow rate of crossfade smoother is preserved) to allow quick
36     volume and pan changes by instrument scripts for instance.
37 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
38     properly and thus were ignored for certain uses.
39 schoenebeck 3018 - Added new C++ API method
40     VirtualMidiDevice::SendChannelPressureToSampler().
41 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
42     sub threads is 16-byte aligned
43 schoenebeck 3054 - fixed numerous compiler warnings
44 persson 2837
45 schoenebeck 2866 * packaging changes:
46     - removed unnecessary dependency to libuuid
47     (originated by libgig's usage of it)
48 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
49     auto detect whether it (sh/c)ould output its messages in color.
50 schoenebeck 2866
51 schoenebeck 2871 * Real-time instrument scripts:
52     - Implemented scheduler for delayed MIDI events and for suspended scripts.
53     - Built-in script function "wait()": implemented support for function's
54     "duration-us" argument, thus scripts using this function are now
55     correctly resumed after the requested amount of microseconds.
56     - Built-in script function "play_note()": implemented support for
57     function's "duration-us" argument, thus notes triggered with this
58     argument are now correctly released after the requested amount of
59     microseconds.
60     - Fix: script events were not cleared when engine channel was reset,
61     potentially causing undefined behavior.
62     - Fixed crash which happened when trying to reference an undeclared
63     variable.
64 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
65     special value -1 for "duration-us" argument, which will cause the
66     triggered note to be released once the original note was released.
67 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
68     - Added new API method ScriptVM::syntaxHighlighting() which provides
69     a convenient syntax highlighting backend for external instrument
70     script editor applications.
71 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
72     - Extended parser issues to provide not only first line and first
73     column, but also last line and last column of issue (thus marking
74     the precise span of the issue within the source code).
75 schoenebeck 2902 - Reload script automatically after being modified by an instrument
76     editor.
77 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
78     like "on note end on".
79 schoenebeck 2931 - Implemented built-in script function "change_vol()".
80     - Implemented built-in script function "change_tune()".
81     - Implemented built-in script function "change_pan()".
82 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
83     - Implemented built-in script function "change_reso()".
84     - Implemented built-in script function "event_status()".
85     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
86     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
87     "event_status()" function.
88     - NKSP language: Added support for bitwise operators ".or.", ".and."
89     and ".not.".
90     - NKSP language scanner: Fixed IDs matching to require at least one
91     character (i.e. when matching function names or variable names).
92     - NKSP language scanner: disabled unusued rules.
93 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
94     be distinguished engine internally from "real" MIDI note on/off
95     events in order to avoid misbehaviors like hanging notes.
96 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
97     - Implemented built-in script variable "$NKSP_REAL_TIMER".
98     - Implemented built-in script variable "$NKSP_PERF_TIMER".
99     - Implemented built-in script variable "$ENGINE_UPTIME".
100 schoenebeck 2945 - Implemented built-in script function "inc()".
101     - Implemented built-in script function "dec()".
102     - NKSP language fix: division expressions were evaluated too often.
103     - NKSP language fix: string concatenation operator was right
104     associative instead of left (to right).
105 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
106     (i.e. "if end if").
107 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
108     - Implemented built-in script variable "$NI_CALLBACK_ID".
109     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
110     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
111     - Added support for read-only built-in variables (respectively
112     handled by the script parser).
113     - Added built-in script constant "$NI_CB_TYPE_INIT".
114     - Added built-in script constant "$NI_CB_TYPE_NOTE".
115     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
116     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
117 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
118 schoenebeck 2953 - Implemented built-in script function "change_attack()".
119     - Implemented built-in script function "change_decay()".
120     - Implemented built-in script function "change_release()".
121 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
122     synthesis parameter changes immediately in case the respective note
123     was triggered at the same time, instead of scheduling the parameter
124     change, especially because it would cause some parameter types's
125     changes either to be ramped (i.e. change_vol()) or other types even
126     to have not effect at all (i.e. change_attack()).
127 schoenebeck 2965 - Implemented built-in script function "sh_left()".
128     - Implemented built-in script function "sh_right()".
129 schoenebeck 2970 - Implemented built-in script function "min()".
130     - Implemented built-in script function "max()".
131 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
132     was loaded.
133     - NKSP built-in wait() script function: abort script execution if
134     a negative or zero wait time was passed as argument (since this is
135     a common indication of a bug either of the script or even of the
136     engine, which could lead to RT instability or even worse).
137 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
138     threatening scripts.
139 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
140 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
141     initializer list to an array variable.
142 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
143 schoenebeck 3076 - Implemented built-in script function "in_range()".
144 schoenebeck 2871
145 schoenebeck 3050 * Instruments DB:
146     - Fixed memory access bug of general DB access code which lead to
147     undefined behavior.

160 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
161 persson 2197 - minor Makefile fix for building lscpparser when build and source
162     directories are separate
163 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to

185 persson 2519 - enabled automake 'subdir-objects' option and moved external
186     source references (vst, au, asio) from makefiles to cpp files,
187     in order to get rid of warnings from automake 1.14
188 persson 2382
189 persson 2086 * general changes:
190 iliev 2012 - Refactoring: moved the independent code from
191     the Gigasampler format engine to base classes
192 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
193     respective profiling code is currently broken
194 schoenebeck 2053 - Introduced support for optional environment variable
195     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
196     where the sampler shall look for instrument editor plugins
197     (patch by Luis Garrido, slightly modified).
198 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
199     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
200     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
201     note (in this implementation of the sampler its simply hard routed to
202     the 1st effect send of the sampler channel, no matter what the actual
203     effect type is)
204     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
205     note (in this implementation of the sampler its simply hard routed to
206     the 2nd effect send of the sampler channel, no matter what the actual
207     effect type is)
208 schoenebeck 2124 - implemented support for internal LADSPA effects
209 schoenebeck 2140 - raised limit of program change queue from 100 to 512
210     (as suggested by Alex Stone)

212 iliev 2296 - experimental support for per voice equalization
213 iliev 2306 - added command line option --exec-after-init
214 schoenebeck 2330 - Introduced new C++ API method:
215     EngineChannel::InstrumentFileName(int index)
216     allowing to retrieve the whole list of files used for the loaded
217     instrument on an engine channel (a.k.a. part). Some GigaStudio
218     instruments for example are splitted over several files like
219     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
220 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
221     - Added new C++ API method Sampler::GetGlobalMaxStreams().
222     - Added new C++ API method Sampler::SetGlobalMaxVoices().
223     - Added new C++ API method Sampler::SetGlobalMaxStreams().
224 schoenebeck 2377 - Various "const" and "restrict" optimizations.
225 persson 2382 - all engines: add pan CC value to instrument pan parameter before
226     applying panning, instead of using two separate pan functions in
227     series (#182)
228 persson 2427 - added a lock guard class for exception safe mutex handling and
229     used it everywhere appropriate
230 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
231     - Exposed scale tuning to C++ API (along to the already existing standard
232     SysEx way).
233 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
234     and broken for ppc64. (Seq_cst loads and stores are actually not
235     used in LS, so the bug wasn't noticable.)
236     - lsatomic.h: added ARMv7 support
237 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
238     added various new C++ methods for this new feature / design change, old
239     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
240     as deprecated but are still there and should provide full behavior
241     backward compatibility).
242     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
243     unsafe and caused compilation error with clang 2.x).
244 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
245 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
246     sampler from the command line by providing LSCP aware features.
247 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
248     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
249     - VirtualMidiDevice: Added support for pitch bend.
250 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
251     polyphonic key pressure events (so far polyphonic pressure was not
252     supported at all, and channel pressure was rerouted as CC128 but not
253     used so far).
254 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
255     code is shared by all sampler engine implemementations, however only the
256     gig file format currently provides support for storing instrument scripts
257     (as LinuxSampler extension to the original GigaStudio 4 format).
258 iliev 2012
259 persson 2043 * Gigasampler format engine:
260     - implemented the "round robin keyboard" dimension
261     - fixed round robin and random dimensions for cases when number of
262     dimension zones is not a power of two
263     - made round robin use a counter for each region instead of each
264     key
265 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
266     - bugfix: filter keyboard tracking was broken
267     - filter performance fix (an unnecessary copy was made of the
268     filter parameters in each sub fragment)
269     - handle special case when pan parameter in gig file has max or
270     min value
271 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
272     doesn't sound naturally with a drumkit
273 persson 2408 - fixed EG1 modulation when attack or release is zero
274 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
275 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
276     conditions (see also previous commit on libgig).
277 persson 2673 - fixed behaviour of filter LFO
278 persson 2043
279 schoenebeck 2047 * SFZ format engine:

281 persson 2055 - added support for v2 multiple stage envelope generators
282     - added a fine-tuned v1 envelope generator instead of using the
283     one from the gig engine
284 persson 2058 - fixed memory leak and memory handling errors
285 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
286 persson 2058 - allow non-numerical key values ("C#4" for example)
287     - "key" opcode now sets pitch_keycenter too
288     - fixed error when unloading instrument with same sample used by
289     multiple regions

695     causing e.g. the libgig test to fail when
696     "./configure --disable-jack-driver" was used
697     (patch by Alexis Ballier)

711     - fix for new mingw-w64 version, which has usleep
712 schoenebeck 1639
713 schoenebeck 1601 * general changes:

715     load as we used a non-portable Linux specific struct field
716     (fixes bug #70, patch by Ronald Baljeu)
717 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
718     plugin DLL on Windows systems failed

720     - optimized the SynchronizedConfig class so it doesn't wait
721     unnecessarily long after an update
722 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
723     events (e.g. to highlight the pressed keys on the virtual keyboard
724     of gigedit)
725 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
726 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
727 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
728     is only used by very few systems, most pick the int math
729     implementation, which is usually faster)
730 persson 1748 - fixes for audio drivers with varying buffer sizes
731 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
732     VST plugin

737 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
738 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
739 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
740     be switched on by command line option "--stacktrace" (the automatic
741     stacktrace mechanism seems to be broken on most systems at the moment)
742 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
743     a pointer to the launched InstrumentEditor object
744 schoenebeck 1876 - added optional 3rd party user data parameter for following
745     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
746     InstrumentEditor::Launch(),

748 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
749     model more strictly
750 persson 1895 - fixes for using large audio device buffers
751 persson 1951 - Windows: add the installation directory to the DLL search path

754 schoenebeck 2509 - updated linuxsampler man page
755 schoenebeck 1601
756 schoenebeck 1599 * audio driver:
757     - removed the nonsense audio channel constraint (which was hard coded to
758     max. 100 audio channels) for most audio drivers
759 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
760     opposed to the LSCP specs
761 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
762     reflected the wrong value
763 persson 1644 - fixed a memory management bug in ASIO driver
764 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
765 persson 1777 - JACK: use jack_client_open instead of the deprecated
766 persson 1748 jack_client_new
767 iliev 1829 - added (experimental) CoreAudio driver
768 persson 1888 - applied old fixes to the ASIO driver that were included in the
769     previous binary release but accidentally never committed to CVS
770     (fixes #117)
771 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
772     win64)
773 persson 1895 - VST: added support for sample rate and buffer size changes
774     - VST: close editor (Fantasia) when the VST is removed

779     stereo
780 persson 1922 - added channel routing, fxsends and midi maps to the settings
781     stored in the plugin state
782 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
783     AudioChannel::CopyTo() methods using GCC vector exensions
784     (if available)
785 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
786     exception when getting parameters from a disconnected device
787 schoenebeck 1599
788 persson 1651 * MIDI driver:
789     - added JACK MIDI driver
790 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
791     want to (mis)use it for some purpose ("fixed" in all current MIDI
792     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
793 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
794 persson 1887 CoreMidi or AU
795 persson 1889 - fixed mingw-w64 compilation error in MME driver
796 persson 1924 - made program change handling in MIDI thread real-time safe by
797     moving the logic to a non-RT thread

799 persson 1651
800 schoenebeck 1604 * instruments database:
801 iliev 1603 - avoid time consuming samples scanning when adding instruments
802     to the instruments database
803 iliev 1727 - added support for handling lost files in the instruments database
804 iliev 1781 - Implemented option for adding instruments in separate directories
805     in the instruments database
806     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
807 persson 1908 - work-around for missing fnmatch function on Windows to make
808     instrument database compilable
809 schoenebeck 1930 - added instrument database support on Windows
810     works with both standalone mode and VST plugin.
811     the instruments DB file is located in
812     %USERPROFILE%\.linuxsampler\instruments.db which allows different
813     databases for each windows user
814     if no DB is present it automatically creates the .linuxsampler subdir
815     and then creates an empty DB
816 persson 1943 - fixed recursive import, which was broken on Windows
817 iliev 1603
818 persson 1644 * Gigasampler format engine:
819     - fixed a memory leak that could happen when a channel was deleted
820     while notes were playing
821 persson 1646 - made it possible to load an instrument even if the audio thread
822     isn't running
823 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
824     enough for piano gigs with pedal noise samples
825 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
826     respective FX send MIDI controller was used
827 schoenebeck 1724 - added support for GM global device volume SysEx message
828 schoenebeck 1762 (can be selected at compile time to either apply globally to the
829     whole sampler [default] or only to the sampler channels that are
830     connected to the respective MIDI input port the SysEx message arrived
831     on)
832 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
833     sometimes wrongly killed in the same buffer, causing no sound to
834     be played
835 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
836     which is usally used to switch a part between chromatic sounds and
837     drumkit sounds (as opposed to their common default setting of MIDI
838     part 10 being a drumkit part and all other ones chromatic parts), in
839     LS however one can switch between the first 16 MIDI instrument maps
840     defined for the sampler
841 persson 1764 - made it possible to create multiple sample channels even if the
842     audio thread isn't running
843 persson 1844 - fixed crash when removing channel with active voices (#116)
844 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
845     un-cache the respective sample if it's really not used by any
846     sampler engine anymore
847     - re-cache samples in case they were changed by an instrument editor,
848     e.g. when a sample was added while playing (#82)
849 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
850     same time stamp as the voice's note-on event and occured both in the
851     same audio fragment cycle (fixes bug #112)
852 persson 1858 - added support for the "fine tune" and "pitch bend range"
853     instrument-level gig parameters
854     - fixed minor artifacts in pitch bend handling
855 schoenebeck 1860 - added support for GS Reset SysEx message
856 persson 1862 - allow gig files to use unlimited downward pitch shifting
857     - added a limit check for upward pitch shifting
858 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
859     note was silent
860 persson 1923 - fixed crash happening when a pitch bend event arrived at the
861     same time a new instrument was loading
862 persson 1644
863 schoenebeck 1687 * LSCP server:
864     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
865     react on MIDI data arriving on certain sampler channels (so far only
866     Note-On and Note-Off events are sent via this LSCP event)
867 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
868     react on MIDI data arriving on certain MIDI input devices (so far only
869     Note-On and Note-Off events are sent via this LSCP event)
870 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
871     SET DB_INSTRUMENT FILE_PATH
872 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
873     frontends to send MIDI messages to specific sampler channel
874     - added two additional fields to GET FILE INSTRUMENT INFO command -
875     KEY_BINDINGS and KEYSWITCH_BINDINGS
876 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
877     was incorrect
878 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
879 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
880     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
881     be triggered respectively
882     - added new LSCP command "SET STREAMS" to globally alter the maximum
883     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
884     which will be triggered respectively
885 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
886     a gigedit file dialog is opened)
887 iliev 1848 - close all connections when LSCPServer is deleted
888 iliev 1882 - hard close of all sockets on exit
889 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
890     driver
891 schoenebeck 1687
892 iliev 1761 * Bug fixes:
893     - fixed a crash which occurs when removing a sampler channel waiting
894     to start instrument loading after another channel
895 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
896     instrument loading in progress (bug #113)
897 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
898     instrument with PERSISTENT load mode
899 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
900     - fixed memory leaks when issuing the following LSCP commands:
901     GET AUDIO_OUTPUT_DRIVER INFO
902     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
903     GET MIDI_INPUT_DRIVER INFO
904     GET MIDI_INPUT_DRIVER_PARAMETER INFO
905     - fixed possible compilation error when sqlite is not present
906 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
907 iliev 1847 - fixed crash when changing the audio output device of a sampler
908     channel with loaded instrument and start playing notes
909 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
910 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
911     PowerPC, which probably could cause crashes on that platform
912 persson 1889 - fixed a memory management error which could cause a crash when a
913     plugin was unloaded
914 persson 1896 - bugfix: two private structs had the same name, which could cause
915     problems if the linker chose the wrong constructor
916 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
917     Windows
918 iliev 1761
919    
920 schoenebeck 1560 Version 0.5.1 (6 December 2007)
921 schoenebeck 1454
922     * packaging changes:
923     - added autoconf checks for pthread library
924     - added autoconf check for pthread bug found on certain NPTL-enabled
925     glibc versions (see Gentoo bug report #194076)
926 senoner 1502 - added autoconf checks for MS Windows
927 schoenebeck 1454
928 persson 1455 * general changes:
929     - bugfix: the thread used by an editor plugin didn't die when the
930     editor closed
931 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
932     out all the space. operator--() did not apply size_mask after
933     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
934     order to avoid problems with the _NonVolatileReader functions.
935     - bugfix: Stream.h: added a missing divide by BytesPerSample in
936     GetWriteSpace(). Since this function is currently only used in
937     the stream's qsort() compare function, it didn't trigger any
938     bugs.
939     - Resampler.h, Synthesizer.h: cubic interpolation now works in
940     24bit mode too. Faster method to read 24bit words on little
941     endian machines (x86): replaced 3 byte reads + shifts with a 1
942     unaligned 32bit read and shift
943     - experimental support for MS Windows (MIDI input via MME, AUDIO
944     output via ASIO)
945     - made handling of SIGINT signal (Ctrl-C) a bit more robust
946 iliev 1541 - support for monitoring the total number of active disk streams
947     (new LSCP commands: GET TOTAL_STREAM_COUNT,
948     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
949 persson 1455
950 senoner 1500 * AUDIO driver:
951 persson 1534 - added Windows ASIO low latency audio driver
952 senoner 1500
953 senoner 1485 * MIDI driver:
954 schoenebeck 1495 - added MME Windows MIDI driver
955 senoner 1485
956 schoenebeck 1471 * LSCP server:
957     - added support for Windows style path / filenames, however with
958     forward slash path separators instead of backslash
959     (i.e. "C:/foo/bar.gig")
960 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
961     apostrophes as well
962 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
963     "LIST FILE INSTRUMENTS <file>" and
964     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
965     about an arbitrary instrument file on the system where the sampler is
966     running on
967 schoenebeck 1471
968 schoenebeck 1424 Version 0.5.0 (15 October 2007)
969 schoenebeck 947
970 schoenebeck 1065 * packaging changes:
971 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
972     API header files anymore
973 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
974     the Doxygen API documentation (explicitly listed in Doxyfile.in)
975 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
976     capable to execute our autoconf environment, thus no need anymore
977     to maintain the compile time configuration file (osx/version.h) for
978     OSX manually (patch by Toshi Nagata)
979 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
980     parameters
981 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
982     C++ API header files, all implementation internal global definitions
983     are now in global_private.h
984     - atomic.h is not exposed to the C++ API anymore
985     - no need to include config.h anymore for using LS's API header files
986     - fixed warnings in API doc generation
987 schoenebeck 1065
988 schoenebeck 947 * general changes:
989     - replaced the old, confusing MIDI program change mechanism by a
990     flexible MIDI instrument mapper which allows to map arbitrary
991 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
992 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
993     loaded on the respective channel when such MIDI program change
994     messages arrive, beside that, each entry allows to define a life-time
995     strategy for the instrument, so the user can define whether the
996     instrument should i.e. be permanently loaded (to be able to switch
997     quickly among sounds) or i.e. loaded just on demand when the
998     respective program change arrives (to safe RAM space), as well as a
999     global volume factor for each entry, so the user can adjust the volume
1000     dynamic of his mapped instrument collection without having to modify
1001 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1002     MIDI instrument maps and assign each sampler channel individually
1003     a certain map, so that i.e. separation of normal instruments and
1004     drumkits is possible
1005 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1006     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1007 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1008     due to a constant size RingBuffer FIFO which is now replaced by a
1009     dynamic (unlimited) size std::list FIFO
1010 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1011     output channels for being processed by external effect processors
1012     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1013     controllers
1014 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1015 iliev 1130 - Implemented new, improved notification system
1016 schoenebeck 1149 - fixed compilation errors regarding OSX
1017     (patch by Toshi Nagata)
1018 iliev 1161 - implemented instruments database
1019 iliev 1345 - added support for escape sequences to the instruments database
1020 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1021     within the sampler's process (by using instrument editor plugins),
1022     you'll notice the new "Registered instrument editors:" message on
1023 schoenebeck 1407 startup, added a new LSCP command:
1024     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1025 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1026     given sampler channel, the plugin path can be overridden at compile
1027     time with ./configure --enable-plugin-dir=/some/dir
1028 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1029     in the sampler's process to safely edit instruments while playing
1030     without a crash (hopefully) by either suspending single regions
1031     wherever possible or if unavoidable whole engine(s)
1032 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1033     policy and priority on thread level, set a minimum stack size for
1034     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1035     threads simply inherited properties of starting thread instead of
1036     setting their own policy and priority
1037 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1038     main process did not wait for the stack trace process to finish
1039     its output
1040 persson 1248 - fixed some minor memory leaks
1041 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1042     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1043 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1044     register, to avoid relocations in the text segment at runtime)
1045 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1046 schoenebeck 947
1047     * MIDI driver:
1048     - dispatch bank select (MSB and LSB) messages
1049    
1050 schoenebeck 1049 * audio driver:
1051     - the ALSA audio output driver parameters now reflect the correct
1052     parameter value ranges for the respective selected sound card
1053     (patch by Till Wimmer, a bit fixed and extended)
1054    
1055 persson 951 * Gigasampler format engine:
1056     - if a filter is used and EG2 finishes before EG1, let the voice
1057     die when EG2 has finished (this fixes a problem with clicks and
1058     voice starvation for some gigs)
1059 persson 1038 - playback is no longer disabled during instrument loading
1060     - all notes playing on a channel that changes its instrument keep
1061     playing with the old instrument until they get a note off
1062     command
1063 persson 1039 - EG fix: a release value of zero could cause noises or crash
1064 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1065 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1066     above max sustain level, which means that there is a decay phase
1067     even if sustain is 100%
1068 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1069     noises or crashes
1070 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1071 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1072     supplied to the configure script (fixes #46)
1073 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1074     instead of a fix value
1075 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1076     127 (solo mode) only kill voices if the respective mode really
1077     changed
1078 persson 951
1079 schoenebeck 1244 * LSCP server:
1080     - fixed compile time error for old Bison versions
1081     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1082 schoenebeck 1245 - parser now supports extended ASCII character set
1083     (up to ASCII code 255, i.e. includes now umlauts and accents)
1084     - filename arguments in LSCP commands now allow to use escape
1085     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1086     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1087     code value like \xf2) (fixes bug #24)
1088 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1089     least one of their text-based parameters (i.e. name, description):
1090     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1091     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1092     "SET DB_INSTRUMENT_DIRECTORY NAME",
1093     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1094     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1095     "FIND DB_INSTRUMENT_DIRECTORIES"
1096 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1097     occured, the unexpected character and the actually expected, possible
1098     character(s), the latter only if less than 5 possibilities)
1099 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1100     settings
1101 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1102     of strings were treated as being one string containing commas
1103     (fixes #57)
1104 schoenebeck 1244
1105 iliev 959 * Bug fixes:
1106     - fixed crash occurring on certain LSCP scripts (Bug 39)
1107 persson 1038 - another thread safety fix for lscp "load engine" and "set
1108     channel audio output device"
1109 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1110     on a sampler channel with connected MIDI device
1111 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1112     device connected to a sampler channel to number less then or equal
1113     to the index of the port to which the sampler channel is connected.
1114 iliev 1296 - The previous bindings were not been disconnected when altering
1115     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1116     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1117 iliev 1297 - The active stream/voice count statistic was incorrect.
1118 iliev 1298 - notification events were not been sent for some sampler
1119     channel changes
1120 iliev 1305 - added default min and max values to restrict the number of allowed
1121     audio output channels and MIDI input ports
1122 iliev 1306 - the connection to the PCM interface is now closed when destroying
1123     an audio output device
1124 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1125 iliev 959
1126 schoenebeck 1221 * test cases:
1127     - updated and fixed (haven't been touched in a while)
1128    
1129 schoenebeck 937 Version 0.4.0 (24 November 2006)
1130 persson 696
1131 schoenebeck 697 * packaging changes:
1132 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1133     to post-(un)install steps; added devel package for liblinuxsampler;
1134     to linuxsampler.spec (RPM)
1135 schoenebeck 697 - install necessary development header files for allowing 3rd party
1136     applications to link against liblinuxsampler
1137     - liblinuxsampler's API documentation can be generated with 'make docs'
1138     (Doxygen required)
1139 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1140     implementation (currently either an integer math solution or a
1141     di-harmonic approximation), automatic detection can be overriden
1142     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1143     configure script argument though (mandatory for cross-compilation)
1144 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1145     provided some on his own (as CXXFLAGS)
1146 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1147     messages
1148 schoenebeck 852 - added compile time options to allow disabling the various audio and
1149     MIDI drivers
1150 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1151     (patch by Ebrahim Mayat)
1152 schoenebeck 697
1153 persson 696 * Gigasampler format engine:
1154 schoenebeck 738 - extensive synthesis optimization
1155     (reimplementation of EGs and LFO(s), removed synthesis parameter
1156     prerendering and the synthesis parameter matrix in general, splitting
1157     each audio fragment into subfragments now where each subfragment uses
1158 persson 830 constant pitch and filter coefficients. The volume coefficient is
1159     linearly interpolated inside a subfragment, unless
1160     --disable-interpolate-volume is set.)
1161 persson 696 - fine tuning of the EG modulation parameters
1162 persson 729 - improved filter cutoff calculation by adding support for the
1163     following gig parameters: Cutoff freq (used when no cutoff
1164     controller is defined), Control invert, Minimum cutoff, Velocity
1165 persson 791 curve and Velocity range. The keyboard tracking now scales
1166     cutoff frequency instead of resonance.
1167 persson 877 - added support for gig parameter Resonance.
1168 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1169 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1170     which can be overridden with --enable-global-attenuation
1171 persson 783 - EG fixes: made the length of "attack hold" stage more
1172     accurate. Release stage can now start before attack stage
1173 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1174     time now has a minimal value to prevent clicks.
1175 persson 799 - fixed pitch changes larger than one octave
1176 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1177     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1178     all modes can be altered via standard GM messages, that is CC5 for
1179     altering portamento time, CC65 for enabling / disabling portamento
1180     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1181 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1182     parameter) and crossfade
1183 persson 831 - added support for the "attenuation controller threshold" gig
1184     parameter
1185 persson 832 - added smoothing of volume changes caused by control change
1186     messages
1187 persson 865 - sample loop parameters are now taken from the DimensionRegion
1188     instead of the wave chunk
1189     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1190     not equal to a power of two
1191 persson 877 - reimplementation of the filter algorithm. The new filter is more
1192     accurate and supports all gig filter types, including bandreject
1193     and lowpass turbo.
1194 persson 903 - real support for 24 bit samples - samples are not truncated to
1195     16 bits anymore
1196     - support for aftertouch (channel pressure, not polyphonic
1197     aftertouch)
1198 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1199     amplifying from 0)
1200 persson 696
1201 schoenebeck 711 * LSCP server:
1202     - fixed application exit on broken pipe error (fixes bug #20)
1203 iliev 793 - fixed the notification messages delay due to lack of
1204     network activity (fixes bug #26)
1205 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1206     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1207 schoenebeck 711
1208 schoenebeck 838 * audio driver:
1209     - added aRts audio output driver (by no means RT safe)
1210    
1211 schoenebeck 775 * MIDI driver:
1212     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1213     messages several times instead of once
1214 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1215     for events (i.e. for offline rendering based MIDI drivers)
1216 persson 922 - added checks for bad MIDI data
1217 schoenebeck 775
1218 schoenebeck 900 * linuxsampler application:
1219     - show available sampler engine types on startup
1220    
1221 schoenebeck 705 * general changes:
1222     - support for muting sampler channels and solo mode of the same, two new
1223     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1224     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1225     introduced for this, the behavior is the same like on a mixer console
1226 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1227     --enable-process-muted-channels which can be used to enable the
1228     processing of muted channels.
1229 iliev 777 - support for sostenuto pedal
1230 iliev 779 - support for monitoring the total number of active voices
1231 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1232     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1233 persson 835 - fixed some memory management errors
1234 persson 841 - fixed some concurrency problems that could lead to crashes when
1235     LSCP commands were executed
1236 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1237     sampler channel (fixes bug #36)
1238 schoenebeck 705
1239 schoenebeck 692 Version 0.3.3 (15 July 2005)
1240 schoenebeck 686
1241     * packaging changes:
1242     - fixed compilation with gcc 4.0
1243    
1244 schoenebeck 687 * Gigasampler format engine:
1245     - LFO preprocessing was performed even though the respective LFO was
1246     disabled by the instrument patch (minor efficiency fix)
1247 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1248     for volume ramp downs in the same fragment (needed for current voice
1249     stealing implementation) then simply inform the user with a warning
1250     about possible click sounds and reduce the volume ramp down
1251     appropriately instead of cancelling the audio device connection
1252 schoenebeck 687
1253 schoenebeck 677 Version 0.3.2 (24 June 2005)
1254 schoenebeck 609
1255     * packaging changes:
1256     - updated autotools build files to compile on OS X
1257     (conditional compilation of CoreMIDI and MidiShare drivers)
1258 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1259     './configure --disable-asm' (definitely not recommended)
1260 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1261     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1262     (due to 'dist-bzip2' automake option)
1263 schoenebeck 649
1264     * Gigasampler format engine:
1265     - support for the gig parameters for "release velocity response" curves
1266     - fine tuning of the EGADSR envelope
1267     - volume of release triggered samples now depends on note-on velocity,
1268     note length and gig parameter "release trigger decay" instead of
1269     note-off velocity.
1270 schoenebeck 663 - revised voice stealing
1271     (fixes crash and endless loop caused by voice stealing)
1272 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1273 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1274     instead of when the respective voice is actually launched
1275     (fixes undefined behavior if stolen voices belonged to a key group -
1276     this case was followed by a "killed voice survived" error message)
1277 schoenebeck 669 - fixed minor issue with null/silence samples
1278     (those stole voices even though they don't need a voice at all which
1279     resulted in "voice stealing didn't work out" messages)
1280 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1281     instrument or audio output device change
1282 schoenebeck 654
1283 schoenebeck 620 * LSCP server:
1284 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1285 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1286 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1287 schoenebeck 609
1288 schoenebeck 668 * linuxsampler application:
1289     - added command line parameters --lscp-addr and --lscp-port to override
1290     default IP address and port of LSCP server
1291    
1292 schoenebeck 579 Version 0.3.1 (24 May 2005)
1293    
1294     * initial release
