* windows, 32-bit: fixed potential crashes by making sure the stack in
  sub threads is 16-byte aligned

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

146 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
147 persson 2197 - minor Makefile fix for building lscpparser when build and source

173     in order to get rid of warnings from automake 1.14
174 persson 2382
175 persson 2086 * general changes:
176 iliev 2012 - Refactoring: moved the independent code from
177     the Gigasampler format engine to base classes
178 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
179     respective profiling code is currently broken
180 schoenebeck 2053 - Introduced support for optional environment variable
181     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
182     where the sampler shall look for instrument editor plugins
183     (patch by Luis Garrido, slightly modified).
184 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
185     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
186     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
187     note (in this implementation of the sampler its simply hard routed to
188     the 1st effect send of the sampler channel, no matter what the actual
189     effect type is)
190     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
191     note (in this implementation of the sampler its simply hard routed to
192     the 2nd effect send of the sampler channel, no matter what the actual
193     effect type is)
194 schoenebeck 2124 - implemented support for internal LADSPA effects
195 schoenebeck 2140 - raised limit of program change queue from 100 to 512
196     (as suggested by Alex Stone)

198 iliev 2296 - experimental support for per voice equalization
199 iliev 2306 - added command line option --exec-after-init
200 schoenebeck 2330 - Introduced new C++ API method:
201     EngineChannel::InstrumentFileName(int index)
202     allowing to retrieve the whole list of files used for the loaded
203     instrument on an engine channel (a.k.a. part). Some GigaStudio
204     instruments for example are splitted over several files like
205     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
206 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
207     - Added new C++ API method Sampler::GetGlobalMaxStreams().
208     - Added new C++ API method Sampler::SetGlobalMaxVoices().
209     - Added new C++ API method Sampler::SetGlobalMaxStreams().
210 schoenebeck 2377 - Various "const" and "restrict" optimizations.
211 persson 2382 - all engines: add pan CC value to instrument pan parameter before
212     applying panning, instead of using two separate pan functions in
213     series (#182)
214 persson 2427 - added a lock guard class for exception safe mutex handling and
215     used it everywhere appropriate
216 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
217     - Exposed scale tuning to C++ API (along to the already existing standard
218     SysEx way).
219 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
220     and broken for ppc64. (Seq_cst loads and stores are actually not
221     used in LS, so the bug wasn't noticable.)
222     - lsatomic.h: added ARMv7 support
223 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
224     added various new C++ methods for this new feature / design change, old
225     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
226     as deprecated but are still there and should provide full behavior
227     backward compatibility).
228     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
229     unsafe and caused compilation error with clang 2.x).
230 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
231 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
232     sampler from the command line by providing LSCP aware features.
233 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
234     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
235     - VirtualMidiDevice: Added support for pitch bend.
236 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
237     polyphonic key pressure events (so far polyphonic pressure was not
238     supported at all, and channel pressure was rerouted as CC128 but not
239     used so far).
240 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
241     code is shared by all sampler engine implemementations, however only the
242     gig file format currently provides support for storing instrument scripts
243     (as LinuxSampler extension to the original GigaStudio 4 format).
244 iliev 2012
245 persson 2043 * Gigasampler format engine:
246     - implemented the "round robin keyboard" dimension
247     - fixed round robin and random dimensions for cases when number of
248     dimension zones is not a power of two
249     - made round robin use a counter for each region instead of each
250     key
251 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
252     - bugfix: filter keyboard tracking was broken
253     - filter performance fix (an unnecessary copy was made of the
254     filter parameters in each sub fragment)
255     - handle special case when pan parameter in gig file has max or
256     min value
257 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
258     doesn't sound naturally with a drumkit
259 persson 2408 - fixed EG1 modulation when attack or release is zero
260 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
261 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
262     conditions (see also previous commit on libgig).
263 persson 2673 - fixed behaviour of filter LFO
264 persson 2043
265 schoenebeck 2047 * SFZ format engine:
266 iliev 2012 - Initial implementation (not usable yet)
267 persson 2055 - added support for v2 multiple stage envelope generators
268     - added a fine-tuned v1 envelope generator instead of using the
269     one from the gig engine
270 persson 2058 - fixed memory leak and memory handling errors
271 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
272 persson 2058 - allow non-numerical key values ("C#4" for example)
273     - "key" opcode now sets pitch_keycenter too
274     - fixed error when unloading instrument with same sample used by
275     multiple regions

281     - added v1 LFO opcodes to parser (no support in engine yet)
282 persson 2082 - added support for amp_veltrack and amp_velcurve_N
283     - fine-tuned the default velocity curve
284 persson 2086 - added support for transpose
285     - fixed crash when using sw_down/up
286     - improved logic for sw_lokey/hikey/up/down/last
287     - added more v1 aliases to parser
288 persson 2091 - reduced memory usage for sfz data
289 persson 2101 - RT-safeness: avoid malloc in audio thread
290     - fixed a bug that could cause voice stealing to fail
291 persson 2106 - optimized sample lookup

667     (fixes #208)
668 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like

672 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
673     after each other (fixes #231).

695     - fix for new mingw-w64 version, which has usleep
696 schoenebeck 1639
697 schoenebeck 1601 * general changes:
698     - bugfix: on some POSIX systems instrument editor plugins refused to
699     load as we used a non-portable Linux specific struct field
700     (fixes bug #70, patch by Ronald Baljeu)
701 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
702     plugin DLL on Windows systems failed
703 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
704     - optimized the SynchronizedConfig class so it doesn't wait
705     unnecessarily long after an update
706 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
707     events (e.g. to highlight the pressed keys on the virtual keyboard
708     of gigedit)
709 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
710 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
711 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
712     is only used by very few systems, most pick the int math
713     implementation, which is usually faster)
714 persson 1748 - fixes for audio drivers with varying buffer sizes
715 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
716     VST plugin

721 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
722 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
723 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
724     be switched on by command line option "--stacktrace" (the automatic
725     stacktrace mechanism seems to be broken on most systems at the moment)
726 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
727     a pointer to the launched InstrumentEditor object
728 schoenebeck 1876 - added optional 3rd party user data parameter for following
729     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
730     InstrumentEditor::Launch(),
731     InstrumentManager::LaunchInstrumentEditor()
732 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
733     model more strictly
734 persson 1895 - fixes for using large audio device buffers
735 persson 1951 - Windows: add the installation directory to the DLL search path

737     gigedit on systems with other GTK versions installed)
738 schoenebeck 2509 - updated linuxsampler man page
739 schoenebeck 1601
740 schoenebeck 1599 * audio driver:
741     - removed the nonsense audio channel constraint (which was hard coded to
742     max. 100 audio channels) for most audio drivers
743 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
744     opposed to the LSCP specs
745 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
746     reflected the wrong value
747 persson 1644 - fixed a memory management bug in ASIO driver
748 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
749 persson 1777 - JACK: use jack_client_open instead of the deprecated
750 persson 1748 jack_client_new
751 iliev 1829 - added (experimental) CoreAudio driver
752 persson 1888 - applied old fixes to the ASIO driver that were included in the
753     previous binary release but accidentally never committed to CVS
754     (fixes #117)
755 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
756     win64)
757 persson 1895 - VST: added support for sample rate and buffer size changes
758     - VST: close editor (Fantasia) when the VST is removed

763     stereo
764 persson 1922 - added channel routing, fxsends and midi maps to the settings
765     stored in the plugin state
766 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
767     AudioChannel::CopyTo() methods using GCC vector exensions
768     (if available)
769 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
770     exception when getting parameters from a disconnected device
771 schoenebeck 1599
772 persson 1651 * MIDI driver:
773     - added JACK MIDI driver
774 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
775     want to (mis)use it for some purpose ("fixed" in all current MIDI
776     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
777 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
778 persson 1887 CoreMidi or AU
779 persson 1889 - fixed mingw-w64 compilation error in MME driver
780 persson 1924 - made program change handling in MIDI thread real-time safe by
781     moving the logic to a non-RT thread
782 persson 1951 - fixed minor memory leak in ALSA driver
783 persson 1651
784 schoenebeck 1604 * instruments database:
785 iliev 1603 - avoid time consuming samples scanning when adding instruments
786     to the instruments database
787 iliev 1727 - added support for handling lost files in the instruments database
788 iliev 1781 - Implemented option for adding instruments in separate directories
789     in the instruments database
790     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
791 persson 1908 - work-around for missing fnmatch function on Windows to make
792     instrument database compilable
793 schoenebeck 1930 - added instrument database support on Windows
794     works with both standalone mode and VST plugin.
795     the instruments DB file is located in
796     %USERPROFILE%\.linuxsampler\instruments.db which allows different
797     databases for each windows user
798     if no DB is present it automatically creates the .linuxsampler subdir
799     and then creates an empty DB
800 persson 1943 - fixed recursive import, which was broken on Windows
801 iliev 1603
802 persson 1644 * Gigasampler format engine:
803     - fixed a memory leak that could happen when a channel was deleted
804     while notes were playing
805 persson 1646 - made it possible to load an instrument even if the audio thread
806     isn't running
807 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
808     enough for piano gigs with pedal noise samples
809 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
810     respective FX send MIDI controller was used
811 schoenebeck 1724 - added support for GM global device volume SysEx message
812 schoenebeck 1762 (can be selected at compile time to either apply globally to the
813     whole sampler [default] or only to the sampler channels that are
814     connected to the respective MIDI input port the SysEx message arrived
815     on)
816 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
817     sometimes wrongly killed in the same buffer, causing no sound to
818     be played
819 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
820     which is usally used to switch a part between chromatic sounds and
821     drumkit sounds (as opposed to their common default setting of MIDI
822     part 10 being a drumkit part and all other ones chromatic parts), in
823     LS however one can switch between the first 16 MIDI instrument maps
824     defined for the sampler
825 persson 1764 - made it possible to create multiple sample channels even if the
826     audio thread isn't running
827 persson 1844 - fixed crash when removing channel with active voices (#116)
828 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
829     un-cache the respective sample if it's really not used by any
830     sampler engine anymore
831     - re-cache samples in case they were changed by an instrument editor,
832     e.g. when a sample was added while playing (#82)
833 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
834     same time stamp as the voice's note-on event and occured both in the
835     same audio fragment cycle (fixes bug #112)
836 persson 1858 - added support for the "fine tune" and "pitch bend range"
837     instrument-level gig parameters
838     - fixed minor artifacts in pitch bend handling
839 schoenebeck 1860 - added support for GS Reset SysEx message
840 persson 1862 - allow gig files to use unlimited downward pitch shifting
841     - added a limit check for upward pitch shifting
842 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
843     note was silent
844 persson 1923 - fixed crash happening when a pitch bend event arrived at the
845     same time a new instrument was loading
846 persson 1644
847 schoenebeck 1687 * LSCP server:
848     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
849     react on MIDI data arriving on certain sampler channels (so far only
850     Note-On and Note-Off events are sent via this LSCP event)
851 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
852     react on MIDI data arriving on certain MIDI input devices (so far only
853     Note-On and Note-Off events are sent via this LSCP event)
854 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
855     SET DB_INSTRUMENT FILE_PATH
856 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
857     frontends to send MIDI messages to specific sampler channel
858     - added two additional fields to GET FILE INSTRUMENT INFO command -
859     KEY_BINDINGS and KEYSWITCH_BINDINGS
860 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
861     was incorrect
862 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
863 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
864     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
865     be triggered respectively
866     - added new LSCP command "SET STREAMS" to globally alter the maximum
867     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
868     which will be triggered respectively
869 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
870     a gigedit file dialog is opened)
871 iliev 1848 - close all connections when LSCPServer is deleted
872 iliev 1882 - hard close of all sockets on exit
873 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
874     driver
875 schoenebeck 1687
876 iliev 1761 * Bug fixes:
877     - fixed a crash which occurs when removing a sampler channel waiting
878     to start instrument loading after another channel
879 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
880     instrument loading in progress (bug #113)
881 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
882     instrument with PERSISTENT load mode
883 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
884     - fixed memory leaks when issuing the following LSCP commands:
885     GET AUDIO_OUTPUT_DRIVER INFO
886     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
887     GET MIDI_INPUT_DRIVER INFO
888     GET MIDI_INPUT_DRIVER_PARAMETER INFO
889     - fixed possible compilation error when sqlite is not present
890 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
891 iliev 1847 - fixed crash when changing the audio output device of a sampler
892     channel with loaded instrument and start playing notes
893 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
894 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
895     PowerPC, which probably could cause crashes on that platform
896 persson 1889 - fixed a memory management error which could cause a crash when a
897     plugin was unloaded
898 persson 1896 - bugfix: two private structs had the same name, which could cause
899     problems if the linker chose the wrong constructor
900 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
901     Windows
902 iliev 1761
903    
904 schoenebeck 1560 Version 0.5.1 (6 December 2007)
905 schoenebeck 1454
906     * packaging changes:
907     - added autoconf checks for pthread library
908     - added autoconf check for pthread bug found on certain NPTL-enabled
909     glibc versions (see Gentoo bug report #194076)
910 senoner 1502 - added autoconf checks for MS Windows
911 schoenebeck 1454
912 persson 1455 * general changes:
913     - bugfix: the thread used by an editor plugin didn't die when the
914     editor closed
915 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
916     out all the space. operator--() did not apply size_mask after
917     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
918     order to avoid problems with the _NonVolatileReader functions.
919     - bugfix: Stream.h: added a missing divide by BytesPerSample in
920     GetWriteSpace(). Since this function is currently only used in
921     the stream's qsort() compare function, it didn't trigger any
922     bugs.
923     - Resampler.h, Synthesizer.h: cubic interpolation now works in
924     24bit mode too. Faster method to read 24bit words on little
925     endian machines (x86): replaced 3 byte reads + shifts with a 1
926     unaligned 32bit read and shift
927     - experimental support for MS Windows (MIDI input via MME, AUDIO
928     output via ASIO)
929     - made handling of SIGINT signal (Ctrl-C) a bit more robust
930 iliev 1541 - support for monitoring the total number of active disk streams
931     (new LSCP commands: GET TOTAL_STREAM_COUNT,
932     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
933 persson 1455
934 senoner 1500 * AUDIO driver:
935 persson 1534 - added Windows ASIO low latency audio driver
936 senoner 1500
937 senoner 1485 * MIDI driver:
938 schoenebeck 1495 - added MME Windows MIDI driver
939 senoner 1485
940 schoenebeck 1471 * LSCP server:
941     - added support for Windows style path / filenames, however with
942     forward slash path separators instead of backslash
943     (i.e. "C:/foo/bar.gig")
944 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
945     apostrophes as well
946 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
947     "LIST FILE INSTRUMENTS <file>" and
948     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
949     about an arbitrary instrument file on the system where the sampler is
950     running on
951 schoenebeck 1471
952 schoenebeck 1424 Version 0.5.0 (15 October 2007)
953 schoenebeck 947
954 schoenebeck 1065 * packaging changes:
955 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
956     API header files anymore
957 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
958     the Doxygen API documentation (explicitly listed in Doxyfile.in)
959 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
960     capable to execute our autoconf environment, thus no need anymore
961     to maintain the compile time configuration file (osx/version.h) for
962     OSX manually (patch by Toshi Nagata)
963 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
964     parameters
965 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
966     C++ API header files, all implementation internal global definitions
967     are now in global_private.h
968     - atomic.h is not exposed to the C++ API anymore
969     - no need to include config.h anymore for using LS's API header files
970     - fixed warnings in API doc generation
971 schoenebeck 1065
972 schoenebeck 947 * general changes:
973     - replaced the old, confusing MIDI program change mechanism by a
974     flexible MIDI instrument mapper which allows to map arbitrary
975 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
976 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
977     loaded on the respective channel when such MIDI program change
978     messages arrive, beside that, each entry allows to define a life-time
979     strategy for the instrument, so the user can define whether the
980     instrument should i.e. be permanently loaded (to be able to switch
981     quickly among sounds) or i.e. loaded just on demand when the
982     respective program change arrives (to safe RAM space), as well as a
983     global volume factor for each entry, so the user can adjust the volume
984     dynamic of his mapped instrument collection without having to modify
985 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
986     MIDI instrument maps and assign each sampler channel individually
987     a certain map, so that i.e. separation of normal instruments and
988     drumkits is possible
989 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
990     MIDI instrument maps, MIDI instruments, FX sends, global volume.
991 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
992     due to a constant size RingBuffer FIFO which is now replaced by a
993     dynamic (unlimited) size std::list FIFO
994 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
995     output channels for being processed by external effect processors
996     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
997     controllers
998 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
999 iliev 1130 - Implemented new, improved notification system
1000 schoenebeck 1149 - fixed compilation errors regarding OSX
1001     (patch by Toshi Nagata)
1002 iliev 1161 - implemented instruments database
1003 iliev 1345 - added support for escape sequences to the instruments database
1004 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1005     within the sampler's process (by using instrument editor plugins),
1006     you'll notice the new "Registered instrument editors:" message on
1007 schoenebeck 1407 startup, added a new LSCP command:
1008     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1009 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1010     given sampler channel, the plugin path can be overridden at compile
1011     time with ./configure --enable-plugin-dir=/some/dir
1012 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1013     in the sampler's process to safely edit instruments while playing
1014     without a crash (hopefully) by either suspending single regions
1015     wherever possible or if unavoidable whole engine(s)
1016 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1017     policy and priority on thread level, set a minimum stack size for
1018     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1019     threads simply inherited properties of starting thread instead of
1020     setting their own policy and priority
1021 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1022     main process did not wait for the stack trace process to finish
1023     its output
1024 persson 1248 - fixed some minor memory leaks
1025 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1026     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1027 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1028     register, to avoid relocations in the text segment at runtime)
1029 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1030 schoenebeck 947
1031     * MIDI driver:
1032     - dispatch bank select (MSB and LSB) messages
1033    
1034 schoenebeck 1049 * audio driver:
1035     - the ALSA audio output driver parameters now reflect the correct
1036     parameter value ranges for the respective selected sound card
1037     (patch by Till Wimmer, a bit fixed and extended)
1038    
1039 persson 951 * Gigasampler format engine:
1040     - if a filter is used and EG2 finishes before EG1, let the voice
1041     die when EG2 has finished (this fixes a problem with clicks and
1042     voice starvation for some gigs)
1043 persson 1038 - playback is no longer disabled during instrument loading
1044     - all notes playing on a channel that changes its instrument keep
1045     playing with the old instrument until they get a note off
1046     command
1047 persson 1039 - EG fix: a release value of zero could cause noises or crash
1048 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1049 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1050     above max sustain level, which means that there is a decay phase
1051     even if sustain is 100%
1052 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1053     noises or crashes
1054 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1055 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1056     supplied to the configure script (fixes #46)
1057 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1058     instead of a fix value
1059 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1060     127 (solo mode) only kill voices if the respective mode really
1061     changed
1062 persson 951
1063 schoenebeck 1244 * LSCP server:
1064     - fixed compile time error for old Bison versions
1065     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1066 schoenebeck 1245 - parser now supports extended ASCII character set
1067     (up to ASCII code 255, i.e. includes now umlauts and accents)
1068     - filename arguments in LSCP commands now allow to use escape
1069     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1070     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1071     code value like \xf2) (fixes bug #24)
1072 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1073     least one of their text-based parameters (i.e. name, description):
1074     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1075     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1076     "SET DB_INSTRUMENT_DIRECTORY NAME",

1080 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1081     occured, the unexpected character and the actually expected, possible
1082     character(s), the latter only if less than 5 possibilities)
1083 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1084     settings
1085 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1086     of strings were treated as being one string containing commas
1087     (fixes #57)
1088 schoenebeck 1244
1089 iliev 959 * Bug fixes:
1090     - fixed crash occurring on certain LSCP scripts (Bug 39)
1091 persson 1038 - another thread safety fix for lscp "load engine" and "set
1092     channel audio output device"
1093 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1094     on a sampler channel with connected MIDI device
1095 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1096     device connected to a sampler channel to number less then or equal
1097     to the index of the port to which the sampler channel is connected.
1098 iliev 1296 - The previous bindings were not been disconnected when altering
1099     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1100     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1101 iliev 1297 - The active stream/voice count statistic was incorrect.
1102 iliev 1298 - notification events were not been sent for some sampler
1103     channel changes
1104 iliev 1305 - added default min and max values to restrict the number of allowed
1105     audio output channels and MIDI input ports
1106 iliev 1306 - the connection to the PCM interface is now closed when destroying
1107     an audio output device
1108 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1109 iliev 959
1110 schoenebeck 1221 * test cases:
1111     - updated and fixed (haven't been touched in a while)
1112    
1113 schoenebeck 937 Version 0.4.0 (24 November 2006)
1114 persson 696
1115 schoenebeck 697 * packaging changes:
1116 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1117     to post-(un)install steps; added devel package for liblinuxsampler;
1118     to linuxsampler.spec (RPM)
1119 schoenebeck 697 - install necessary development header files for allowing 3rd party
1120     applications to link against liblinuxsampler
1121     - liblinuxsampler's API documentation can be generated with 'make docs'
1122     (Doxygen required)
1123 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1124     implementation (currently either an integer math solution or a
1125     di-harmonic approximation), automatic detection can be overriden
1126     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1127     configure script argument though (mandatory for cross-compilation)
1128 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1129     provided some on his own (as CXXFLAGS)
1130 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1131     messages
1132 schoenebeck 852 - added compile time options to allow disabling the various audio and
1133     MIDI drivers
1134 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1135     (patch by Ebrahim Mayat)
1136 schoenebeck 697
1137 persson 696 * Gigasampler format engine:
1138 schoenebeck 738 - extensive synthesis optimization
1139     (reimplementation of EGs and LFO(s), removed synthesis parameter
1140     prerendering and the synthesis parameter matrix in general, splitting
1141     each audio fragment into subfragments now where each subfragment uses
1142 persson 830 constant pitch and filter coefficients. The volume coefficient is
1143     linearly interpolated inside a subfragment, unless
1144     --disable-interpolate-volume is set.)
1145 persson 696 - fine tuning of the EG modulation parameters
1146 persson 729 - improved filter cutoff calculation by adding support for the
1147     following gig parameters: Cutoff freq (used when no cutoff
1148     controller is defined), Control invert, Minimum cutoff, Velocity
1149 persson 791 curve and Velocity range. The keyboard tracking now scales
1150     cutoff frequency instead of resonance.
1151 persson 877 - added support for gig parameter Resonance.
1152 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1153 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1154     which can be overridden with --enable-global-attenuation
1155 persson 783 - EG fixes: made the length of "attack hold" stage more
1156     accurate. Release stage can now start before attack stage
1157 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1158     time now has a minimal value to prevent clicks.
1159 persson 799 - fixed pitch changes larger than one octave
1160 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1161     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1162     all modes can be altered via standard GM messages, that is CC5 for
1163     altering portamento time, CC65 for enabling / disabling portamento
1164     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1165 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1166     parameter) and crossfade
1167 persson 831 - added support for the "attenuation controller threshold" gig
1168     parameter
1169 persson 832 - added smoothing of volume changes caused by control change
1170     messages
1171 persson 865 - sample loop parameters are now taken from the DimensionRegion
1172     instead of the wave chunk
1173     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1174     not equal to a power of two
1175 persson 877 - reimplementation of the filter algorithm. The new filter is more
1176     accurate and supports all gig filter types, including bandreject
1177     and lowpass turbo.
1178 persson 903 - real support for 24 bit samples - samples are not truncated to
1179     16 bits anymore
1180     - support for aftertouch (channel pressure, not polyphonic
1181     aftertouch)
1182 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1183     amplifying from 0)
1184 persson 696
1185 schoenebeck 711 * LSCP server:
1186     - fixed application exit on broken pipe error (fixes bug #20)
1187 iliev 793 - fixed the notification messages delay due to lack of
1188     network activity (fixes bug #26)
1189 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1190     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1191 schoenebeck 711
1192 schoenebeck 838 * audio driver:
1193     - added aRts audio output driver (by no means RT safe)
1194    
1195 schoenebeck 775 * MIDI driver:
1196     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1197     messages several times instead of once
1198 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1199     for events (i.e. for offline rendering based MIDI drivers)
1200 persson 922 - added checks for bad MIDI data
1201 schoenebeck 775
1202 schoenebeck 900 * linuxsampler application:
1203     - show available sampler engine types on startup
1204    
1205 schoenebeck 705 * general changes:
1206     - support for muting sampler channels and solo mode of the same, two new
1207     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1208     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1209     introduced for this, the behavior is the same like on a mixer console
1210 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1211     --enable-process-muted-channels which can be used to enable the
1212     processing of muted channels.
1213 iliev 777 - support for sostenuto pedal
1214 iliev 779 - support for monitoring the total number of active voices
1215 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1216     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1217 persson 835 - fixed some memory management errors
1218 persson 841 - fixed some concurrency problems that could lead to crashes when
1219     LSCP commands were executed
1220 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1221     sampler channel (fixes bug #36)
1222 schoenebeck 705
1223 schoenebeck 692 Version 0.3.3 (15 July 2005)
1224 schoenebeck 686
1225     * packaging changes:
1226     - fixed compilation with gcc 4.0
1227    
1228 schoenebeck 687 * Gigasampler format engine:
1229     - LFO preprocessing was performed even though the respective LFO was
1230     disabled by the instrument patch (minor efficiency fix)
1231 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1232     for volume ramp downs in the same fragment (needed for current voice
1233     stealing implementation) then simply inform the user with a warning
1234     about possible click sounds and reduce the volume ramp down
1235     appropriately instead of cancelling the audio device connection
1236 schoenebeck 687
1237 schoenebeck 677 Version 0.3.2 (24 June 2005)
1238 schoenebeck 609
1239     * packaging changes:
1240     - updated autotools build files to compile on OS X
1241     (conditional compilation of CoreMIDI and MidiShare drivers)
1242 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1243     './configure --disable-asm' (definitely not recommended)
1244 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1245     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1246     (due to 'dist-bzip2' automake option)
1247 schoenebeck 649
1248     * Gigasampler format engine:
1249     - support for the gig parameters for "release velocity response" curves
1250     - fine tuning of the EGADSR envelope
1251     - volume of release triggered samples now depends on note-on velocity,
1252     note length and gig parameter "release trigger decay" instead of
1253     note-off velocity.
1254 schoenebeck 663 - revised voice stealing
1255     (fixes crash and endless loop caused by voice stealing)
1256 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1257 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1258     instead of when the respective voice is actually launched
1259     (fixes undefined behavior if stolen voices belonged to a key group -
1260     this case was followed by a "killed voice survived" error message)
1261 schoenebeck 669 - fixed minor issue with null/silence samples
1262     (those stole voices even though they don't need a voice at all which
1263     resulted in "voice stealing didn't work out" messages)
1264 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1265     instrument or audio output device change
1266 schoenebeck 654
1267 schoenebeck 620 * LSCP server:
1268 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1269 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1270 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1271 schoenebeck 609
1272 schoenebeck 668 * linuxsampler application:
1273     - added command line parameters --lscp-addr and --lscp-port to override
1274     default IP address and port of LSCP server
1275    
1276 schoenebeck 579 Version 0.3.1 (24 May 2005)
1277    
1278     * initial release
