* Instruments DB: Fixed memory access bug of general DB
  access code which lead to undefined behavior.

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.
134 schoenebeck 2871
135 schoenebeck 3050 * Instruments DB:
136     - Fixed memory access bug of general DB access code which lead to
137     undefined behavior.

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

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

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

287     - fine-tuned the default velocity curve
288 persson 2086 - added support for transpose
289     - fixed crash when using sw_down/up
290     - improved logic for sw_lokey/hikey/up/down/last
291     - added more v1 aliases to parser
292 persson 2091 - reduced memory usage for sfz data
293 persson 2101 - RT-safeness: avoid malloc in audio thread
294     - fixed a bug that could cause voice stealing to fail
295 persson 2106 - optimized sample lookup

671     (fixes #208)
672 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
673     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
674     practically irrelevant, however it caused problems with the new LSCP
675     shell's auto completion feature).
676 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
677     after each other (fixes #231).

697 persson 1923 - fixed building with sqlite installed in a non-standard directory
698 persson 1931 - when cross-compiling, don't try to create instruments.db
699     - fix for new mingw-w64 version, which has usleep
700 schoenebeck 1639
701 schoenebeck 1601 * general changes:
702     - bugfix: on some POSIX systems instrument editor plugins refused to
703     load as we used a non-portable Linux specific struct field
704     (fixes bug #70, patch by Ronald Baljeu)
705 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
706     plugin DLL on Windows systems failed
707 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
708     - optimized the SynchronizedConfig class so it doesn't wait
709     unnecessarily long after an update
710 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
711     events (e.g. to highlight the pressed keys on the virtual keyboard
712     of gigedit)
713 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
714 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
715 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
716     is only used by very few systems, most pick the int math
717     implementation, which is usually faster)
718 persson 1748 - fixes for audio drivers with varying buffer sizes
719 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
720     VST plugin
721 iliev 1789 - notification events for stream/voice count statistics are now sent

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

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

767     stereo
768 persson 1922 - added channel routing, fxsends and midi maps to the settings
769     stored in the plugin state
770 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
771     AudioChannel::CopyTo() methods using GCC vector exensions
772     (if available)
773 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
774     exception when getting parameters from a disconnected device
775 schoenebeck 1599
776 persson 1651 * MIDI driver:
777     - added JACK MIDI driver
778 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
779     want to (mis)use it for some purpose ("fixed" in all current MIDI
780     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
781 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
782 persson 1887 CoreMidi or AU
783 persson 1889 - fixed mingw-w64 compilation error in MME driver
784 persson 1924 - made program change handling in MIDI thread real-time safe by
785     moving the logic to a non-RT thread
786 persson 1951 - fixed minor memory leak in ALSA driver
787 persson 1651
788 schoenebeck 1604 * instruments database:
789 iliev 1603 - avoid time consuming samples scanning when adding instruments
790     to the instruments database
791 iliev 1727 - added support for handling lost files in the instruments database
792 iliev 1781 - Implemented option for adding instruments in separate directories
793     in the instruments database
794     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
795 persson 1908 - work-around for missing fnmatch function on Windows to make
796     instrument database compilable
797 schoenebeck 1930 - added instrument database support on Windows
798     works with both standalone mode and VST plugin.
799     the instruments DB file is located in
800     %USERPROFILE%\.linuxsampler\instruments.db which allows different
801     databases for each windows user
802     if no DB is present it automatically creates the .linuxsampler subdir
803     and then creates an empty DB
804 persson 1943 - fixed recursive import, which was broken on Windows
805 iliev 1603
806 persson 1644 * Gigasampler format engine:
807     - fixed a memory leak that could happen when a channel was deleted
808     while notes were playing
809 persson 1646 - made it possible to load an instrument even if the audio thread
810     isn't running
811 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
812     enough for piano gigs with pedal noise samples
813 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
814     respective FX send MIDI controller was used
815 schoenebeck 1724 - added support for GM global device volume SysEx message
816 schoenebeck 1762 (can be selected at compile time to either apply globally to the
817     whole sampler [default] or only to the sampler channels that are
818     connected to the respective MIDI input port the SysEx message arrived
819     on)
820 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
821     sometimes wrongly killed in the same buffer, causing no sound to
822     be played
823 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
824     which is usally used to switch a part between chromatic sounds and
825     drumkit sounds (as opposed to their common default setting of MIDI
826     part 10 being a drumkit part and all other ones chromatic parts), in
827     LS however one can switch between the first 16 MIDI instrument maps
828     defined for the sampler
829 persson 1764 - made it possible to create multiple sample channels even if the
830     audio thread isn't running
831 persson 1844 - fixed crash when removing channel with active voices (#116)
832 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
833     un-cache the respective sample if it's really not used by any
834     sampler engine anymore
835     - re-cache samples in case they were changed by an instrument editor,
836     e.g. when a sample was added while playing (#82)
837 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
838     same time stamp as the voice's note-on event and occured both in the
839     same audio fragment cycle (fixes bug #112)
840 persson 1858 - added support for the "fine tune" and "pitch bend range"
841     instrument-level gig parameters
842     - fixed minor artifacts in pitch bend handling
843 schoenebeck 1860 - added support for GS Reset SysEx message
844 persson 1862 - allow gig files to use unlimited downward pitch shifting
845     - added a limit check for upward pitch shifting
846 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
847     note was silent
848 persson 1923 - fixed crash happening when a pitch bend event arrived at the
849     same time a new instrument was loading
850 persson 1644
851 schoenebeck 1687 * LSCP server:
852     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
853     react on MIDI data arriving on certain sampler channels (so far only
854     Note-On and Note-Off events are sent via this LSCP event)
855 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
856     react on MIDI data arriving on certain MIDI input devices (so far only
857     Note-On and Note-Off events are sent via this LSCP event)
858 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
859     SET DB_INSTRUMENT FILE_PATH
860 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
861     frontends to send MIDI messages to specific sampler channel
862     - added two additional fields to GET FILE INSTRUMENT INFO command -
863     KEY_BINDINGS and KEYSWITCH_BINDINGS
864 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
865     was incorrect
866 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
867 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
868     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
869     be triggered respectively
870     - added new LSCP command "SET STREAMS" to globally alter the maximum
871     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
872     which will be triggered respectively
873 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
874     a gigedit file dialog is opened)
875 iliev 1848 - close all connections when LSCPServer is deleted
876 iliev 1882 - hard close of all sockets on exit
877 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
878     driver
879 schoenebeck 1687
880 iliev 1761 * Bug fixes:
881     - fixed a crash which occurs when removing a sampler channel waiting
882     to start instrument loading after another channel
883 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
884     instrument loading in progress (bug #113)
885 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
886     instrument with PERSISTENT load mode
887 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
888     - fixed memory leaks when issuing the following LSCP commands:
889     GET AUDIO_OUTPUT_DRIVER INFO
890     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
891     GET MIDI_INPUT_DRIVER INFO
892     GET MIDI_INPUT_DRIVER_PARAMETER INFO
893     - fixed possible compilation error when sqlite is not present
894 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
895 iliev 1847 - fixed crash when changing the audio output device of a sampler
896     channel with loaded instrument and start playing notes
897 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
898 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
899     PowerPC, which probably could cause crashes on that platform
900 persson 1889 - fixed a memory management error which could cause a crash when a
901     plugin was unloaded
902 persson 1896 - bugfix: two private structs had the same name, which could cause
903     problems if the linker chose the wrong constructor
904 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
905     Windows
906 iliev 1761
907    
908 schoenebeck 1560 Version 0.5.1 (6 December 2007)
909 schoenebeck 1454
910     * packaging changes:
911     - added autoconf checks for pthread library
912     - added autoconf check for pthread bug found on certain NPTL-enabled
913     glibc versions (see Gentoo bug report #194076)
914 senoner 1502 - added autoconf checks for MS Windows
915 schoenebeck 1454
916 persson 1455 * general changes:
917     - bugfix: the thread used by an editor plugin didn't die when the
918     editor closed
919 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
920     out all the space. operator--() did not apply size_mask after
921     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
922     order to avoid problems with the _NonVolatileReader functions.
923     - bugfix: Stream.h: added a missing divide by BytesPerSample in
924     GetWriteSpace(). Since this function is currently only used in
925     the stream's qsort() compare function, it didn't trigger any
926     bugs.
927     - Resampler.h, Synthesizer.h: cubic interpolation now works in
928     24bit mode too. Faster method to read 24bit words on little
929     endian machines (x86): replaced 3 byte reads + shifts with a 1
930     unaligned 32bit read and shift
931     - experimental support for MS Windows (MIDI input via MME, AUDIO
932     output via ASIO)
933     - made handling of SIGINT signal (Ctrl-C) a bit more robust
934 iliev 1541 - support for monitoring the total number of active disk streams
935     (new LSCP commands: GET TOTAL_STREAM_COUNT,
936     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
937 persson 1455
938 senoner 1500 * AUDIO driver:
939 persson 1534 - added Windows ASIO low latency audio driver
940 senoner 1500
941 senoner 1485 * MIDI driver:
942 schoenebeck 1495 - added MME Windows MIDI driver
943 senoner 1485
944 schoenebeck 1471 * LSCP server:
945     - added support for Windows style path / filenames, however with
946     forward slash path separators instead of backslash
947     (i.e. "C:/foo/bar.gig")
948 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
949     apostrophes as well
950 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
951     "LIST FILE INSTRUMENTS <file>" and
952     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
953     about an arbitrary instrument file on the system where the sampler is
954     running on
955 schoenebeck 1471
956 schoenebeck 1424 Version 0.5.0 (15 October 2007)
957 schoenebeck 947
958 schoenebeck 1065 * packaging changes:
959 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
960     API header files anymore
961 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
962     the Doxygen API documentation (explicitly listed in Doxyfile.in)
963 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
964     capable to execute our autoconf environment, thus no need anymore
965     to maintain the compile time configuration file (osx/version.h) for
966     OSX manually (patch by Toshi Nagata)
967 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
968     parameters
969 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
970     C++ API header files, all implementation internal global definitions
971     are now in global_private.h
972     - atomic.h is not exposed to the C++ API anymore
973     - no need to include config.h anymore for using LS's API header files
974     - fixed warnings in API doc generation
975 schoenebeck 1065
976 schoenebeck 947 * general changes:
977     - replaced the old, confusing MIDI program change mechanism by a
978     flexible MIDI instrument mapper which allows to map arbitrary
979 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
980 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
981     loaded on the respective channel when such MIDI program change
982     messages arrive, beside that, each entry allows to define a life-time
983     strategy for the instrument, so the user can define whether the
984     instrument should i.e. be permanently loaded (to be able to switch
985     quickly among sounds) or i.e. loaded just on demand when the
986     respective program change arrives (to safe RAM space), as well as a
987     global volume factor for each entry, so the user can adjust the volume
988     dynamic of his mapped instrument collection without having to modify
989 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
990     MIDI instrument maps and assign each sampler channel individually
991     a certain map, so that i.e. separation of normal instruments and
992     drumkits is possible
993 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
994     MIDI instrument maps, MIDI instruments, FX sends, global volume.
995 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
996     due to a constant size RingBuffer FIFO which is now replaced by a
997     dynamic (unlimited) size std::list FIFO
998 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
999     output channels for being processed by external effect processors
1000     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1001     controllers
1002 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1003 iliev 1130 - Implemented new, improved notification system
1004 schoenebeck 1149 - fixed compilation errors regarding OSX
1005     (patch by Toshi Nagata)
1006 iliev 1161 - implemented instruments database
1007 iliev 1345 - added support for escape sequences to the instruments database
1008 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1009     within the sampler's process (by using instrument editor plugins),
1010     you'll notice the new "Registered instrument editors:" message on
1011 schoenebeck 1407 startup, added a new LSCP command:
1012     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1013 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1014     given sampler channel, the plugin path can be overridden at compile
1015     time with ./configure --enable-plugin-dir=/some/dir
1016 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1017     in the sampler's process to safely edit instruments while playing
1018     without a crash (hopefully) by either suspending single regions
1019     wherever possible or if unavoidable whole engine(s)
1020 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1021     policy and priority on thread level, set a minimum stack size for
1022     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1023     threads simply inherited properties of starting thread instead of
1024     setting their own policy and priority
1025 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1026     main process did not wait for the stack trace process to finish
1027     its output
1028 persson 1248 - fixed some minor memory leaks
1029 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1030     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1031 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1032     register, to avoid relocations in the text segment at runtime)
1033 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1034 schoenebeck 947
1035     * MIDI driver:
1036     - dispatch bank select (MSB and LSB) messages
1037    
1038 schoenebeck 1049 * audio driver:
1039     - the ALSA audio output driver parameters now reflect the correct
1040     parameter value ranges for the respective selected sound card
1041     (patch by Till Wimmer, a bit fixed and extended)
1042    
1043 persson 951 * Gigasampler format engine:
1044     - if a filter is used and EG2 finishes before EG1, let the voice
1045     die when EG2 has finished (this fixes a problem with clicks and
1046     voice starvation for some gigs)
1047 persson 1038 - playback is no longer disabled during instrument loading
1048     - all notes playing on a channel that changes its instrument keep
1049     playing with the old instrument until they get a note off
1050     command
1051 persson 1039 - EG fix: a release value of zero could cause noises or crash
1052 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1053 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1054     above max sustain level, which means that there is a decay phase
1055     even if sustain is 100%
1056 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1057     noises or crashes
1058 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1059 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1060     supplied to the configure script (fixes #46)
1061 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1062     instead of a fix value
1063 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1064     127 (solo mode) only kill voices if the respective mode really
1065     changed
1066 persson 951
1067 schoenebeck 1244 * LSCP server:
1068     - fixed compile time error for old Bison versions
1069     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1070 schoenebeck 1245 - parser now supports extended ASCII character set
1071     (up to ASCII code 255, i.e. includes now umlauts and accents)
1072     - filename arguments in LSCP commands now allow to use escape
1073     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1074     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1075     code value like \xf2) (fixes bug #24)
1076 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1077     least one of their text-based parameters (i.e. name, description):
1078     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",

1084 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1085     occured, the unexpected character and the actually expected, possible
1086     character(s), the latter only if less than 5 possibilities)
1087 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1088     settings
1089 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1090     of strings were treated as being one string containing commas
1091     (fixes #57)
1092 schoenebeck 1244
1093 iliev 959 * Bug fixes:
1094     - fixed crash occurring on certain LSCP scripts (Bug 39)
1095 persson 1038 - another thread safety fix for lscp "load engine" and "set
1096     channel audio output device"
1097 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1098     on a sampler channel with connected MIDI device
1099 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1100     device connected to a sampler channel to number less then or equal
1101     to the index of the port to which the sampler channel is connected.
1102 iliev 1296 - The previous bindings were not been disconnected when altering
1103     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1104     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1105 iliev 1297 - The active stream/voice count statistic was incorrect.
1106 iliev 1298 - notification events were not been sent for some sampler
1107     channel changes
1108 iliev 1305 - added default min and max values to restrict the number of allowed
1109     audio output channels and MIDI input ports
1110 iliev 1306 - the connection to the PCM interface is now closed when destroying
1111     an audio output device
1112 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1113 iliev 959
1114 schoenebeck 1221 * test cases:
1115     - updated and fixed (haven't been touched in a while)
1116    
1117 schoenebeck 937 Version 0.4.0 (24 November 2006)
1118 persson 696
1119 schoenebeck 697 * packaging changes:
1120 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1121     to post-(un)install steps; added devel package for liblinuxsampler;
1122     to linuxsampler.spec (RPM)
1123 schoenebeck 697 - install necessary development header files for allowing 3rd party
1124     applications to link against liblinuxsampler
1125     - liblinuxsampler's API documentation can be generated with 'make docs'
1126     (Doxygen required)
1127 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1128     implementation (currently either an integer math solution or a
1129     di-harmonic approximation), automatic detection can be overriden
1130     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1131     configure script argument though (mandatory for cross-compilation)
1132 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1133     provided some on his own (as CXXFLAGS)
1134 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1135     messages
1136 schoenebeck 852 - added compile time options to allow disabling the various audio and
1137     MIDI drivers
1138 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1139     (patch by Ebrahim Mayat)
1140 schoenebeck 697
1141 persson 696 * Gigasampler format engine:
1142 schoenebeck 738 - extensive synthesis optimization
1143     (reimplementation of EGs and LFO(s), removed synthesis parameter
1144     prerendering and the synthesis parameter matrix in general, splitting
1145     each audio fragment into subfragments now where each subfragment uses
1146 persson 830 constant pitch and filter coefficients. The volume coefficient is
1147     linearly interpolated inside a subfragment, unless
1148     --disable-interpolate-volume is set.)
1149 persson 696 - fine tuning of the EG modulation parameters
1150 persson 729 - improved filter cutoff calculation by adding support for the
1151     following gig parameters: Cutoff freq (used when no cutoff
1152     controller is defined), Control invert, Minimum cutoff, Velocity
1153 persson 791 curve and Velocity range. The keyboard tracking now scales
1154     cutoff frequency instead of resonance.
1155 persson 877 - added support for gig parameter Resonance.
1156 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1157 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1158     which can be overridden with --enable-global-attenuation
1159 persson 783 - EG fixes: made the length of "attack hold" stage more
1160     accurate. Release stage can now start before attack stage
1161 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1162     time now has a minimal value to prevent clicks.
1163 persson 799 - fixed pitch changes larger than one octave
1164 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1165     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1166     all modes can be altered via standard GM messages, that is CC5 for
1167     altering portamento time, CC65 for enabling / disabling portamento
1168     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1169 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1170     parameter) and crossfade
1171 persson 831 - added support for the "attenuation controller threshold" gig
1172     parameter
1173 persson 832 - added smoothing of volume changes caused by control change
1174     messages
1175 persson 865 - sample loop parameters are now taken from the DimensionRegion
1176     instead of the wave chunk
1177     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1178     not equal to a power of two
1179 persson 877 - reimplementation of the filter algorithm. The new filter is more
1180     accurate and supports all gig filter types, including bandreject
1181     and lowpass turbo.
1182 persson 903 - real support for 24 bit samples - samples are not truncated to
1183     16 bits anymore
1184     - support for aftertouch (channel pressure, not polyphonic
1185     aftertouch)
1186 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1187     amplifying from 0)
1188 persson 696
1189 schoenebeck 711 * LSCP server:
1190     - fixed application exit on broken pipe error (fixes bug #20)
1191 iliev 793 - fixed the notification messages delay due to lack of
1192     network activity (fixes bug #26)
1193 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1194     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1195 schoenebeck 711
1196 schoenebeck 838 * audio driver:
1197     - added aRts audio output driver (by no means RT safe)
1198    
1199 schoenebeck 775 * MIDI driver:
1200     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1201     messages several times instead of once
1202 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1203     for events (i.e. for offline rendering based MIDI drivers)
1204 persson 922 - added checks for bad MIDI data
1205 schoenebeck 775
1206 schoenebeck 900 * linuxsampler application:
1207     - show available sampler engine types on startup
1208    
1209 schoenebeck 705 * general changes:
1210     - support for muting sampler channels and solo mode of the same, two new
1211     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1212     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1213     introduced for this, the behavior is the same like on a mixer console
1214 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1215     --enable-process-muted-channels which can be used to enable the
1216     processing of muted channels.
1217 iliev 777 - support for sostenuto pedal
1218 iliev 779 - support for monitoring the total number of active voices
1219 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1220     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1221 persson 835 - fixed some memory management errors
1222 persson 841 - fixed some concurrency problems that could lead to crashes when
1223     LSCP commands were executed
1224 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1225     sampler channel (fixes bug #36)
1226 schoenebeck 705
1227 schoenebeck 692 Version 0.3.3 (15 July 2005)
1228 schoenebeck 686
1229     * packaging changes:
1230     - fixed compilation with gcc 4.0
1231    
1232 schoenebeck 687 * Gigasampler format engine:
1233     - LFO preprocessing was performed even though the respective LFO was
1234     disabled by the instrument patch (minor efficiency fix)
1235 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1236     for volume ramp downs in the same fragment (needed for current voice
1237     stealing implementation) then simply inform the user with a warning
1238     about possible click sounds and reduce the volume ramp down
1239     appropriately instead of cancelling the audio device connection
1240 schoenebeck 687
1241 schoenebeck 677 Version 0.3.2 (24 June 2005)
1242 schoenebeck 609
1243     * packaging changes:
1244     - updated autotools build files to compile on OS X
1245     (conditional compilation of CoreMIDI and MidiShare drivers)
1246 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1247     './configure --disable-asm' (definitely not recommended)
1248 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1249     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1250     (due to 'dist-bzip2' automake option)
1251 schoenebeck 649
1252     * Gigasampler format engine:
1253     - support for the gig parameters for "release velocity response" curves
1254     - fine tuning of the EGADSR envelope
1255     - volume of release triggered samples now depends on note-on velocity,
1256     note length and gig parameter "release trigger decay" instead of
1257     note-off velocity.
1258 schoenebeck 663 - revised voice stealing
1259     (fixes crash and endless loop caused by voice stealing)
1260 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1261 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1262     instead of when the respective voice is actually launched
1263     (fixes undefined behavior if stolen voices belonged to a key group -
1264     this case was followed by a "killed voice survived" error message)
1265 schoenebeck 669 - fixed minor issue with null/silence samples
1266     (those stole voices even though they don't need a voice at all which
1267     resulted in "voice stealing didn't work out" messages)
1268 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1269     instrument or audio output device change
1270 schoenebeck 654
1271 schoenebeck 620 * LSCP server:
1272 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1273 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1274 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1275 schoenebeck 609
1276 schoenebeck 668 * linuxsampler application:
1277     - added command line parameters --lscp-addr and --lscp-port to override
1278     default IP address and port of LSCP server
1279    
1280 schoenebeck 579 Version 0.3.1 (24 May 2005)
1281    
1282     * initial release
