* ScriptVM: Implemented automatic suspension of RT safety
  threatening scripts.
* Bumped version (2.0.0.svn25).

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 persson 2837
31 schoenebeck 2866 * packaging changes:
32     - removed unnecessary dependency to libuuid
33     (originated by libgig's usage of it)
34 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
35     auto detect whether it (sh/c)ould output its messages in color.
36 schoenebeck 2866
37 schoenebeck 2871 * Real-time instrument scripts:
38     - Implemented scheduler for delayed MIDI events and for suspended scripts.
39     - Built-in script function "wait()": implemented support for function's
40     "duration-us" argument, thus scripts using this function are now
41     correctly resumed after the requested amount of microseconds.
42     - Built-in script function "play_note()": implemented support for
43     function's "duration-us" argument, thus notes triggered with this
44     argument are now correctly released after the requested amount of
45     microseconds.
46     - Fix: script events were not cleared when engine channel was reset,
47     potentially causing undefined behavior.
48     - Fixed crash which happened when trying to reference an undeclared
49     variable.
50 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
51     special value -1 for "duration-us" argument, which will cause the
52     triggered note to be released once the original note was released.
53 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
54     - Added new API method ScriptVM::syntaxHighlighting() which provides
55     a convenient syntax highlighting backend for external instrument
56     script editor applications.
57 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
58     - Extended parser issues to provide not only first line and first
59     column, but also last line and last column of issue (thus marking
60     the precise span of the issue within the source code).
61 schoenebeck 2902 - Reload script automatically after being modified by an instrument
62     editor.
63 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
64     like "on note end on".
65 schoenebeck 2931 - Implemented built-in script function "change_vol()".
66     - Implemented built-in script function "change_tune()".
67     - Implemented built-in script function "change_pan()".
68 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
69     - Implemented built-in script function "change_reso()".
70     - Implemented built-in script function "event_status()".
71     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
72     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
73     "event_status()" function.
74     - NKSP language: Added support for bitwise operators ".or.", ".and."
75     and ".not.".
76     - NKSP language scanner: Fixed IDs matching to require at least one
77     character (i.e. when matching function names or variable names).
78     - NKSP language scanner: disabled unusued rules.
79 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
80     be distinguished engine internally from "real" MIDI note on/off
81     events in order to avoid misbehaviors like hanging notes.
82 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
83     - Implemented built-in script variable "$NKSP_REAL_TIMER".
84     - Implemented built-in script variable "$NKSP_PERF_TIMER".
85     - Implemented built-in script variable "$ENGINE_UPTIME".
86 schoenebeck 2945 - Implemented built-in script function "inc()".
87     - Implemented built-in script function "dec()".
88     - NKSP language fix: division expressions were evaluated too often.
89     - NKSP language fix: string concatenation operator was right
90     associative instead of left (to right).
91 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
92     (i.e. "if end if").
93 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
94     - Implemented built-in script variable "$NI_CALLBACK_ID".
95     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
96     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
97     - Added support for read-only built-in variables (respectively
98     handled by the script parser).
99     - Added built-in script constant "$NI_CB_TYPE_INIT".
100     - Added built-in script constant "$NI_CB_TYPE_NOTE".
101     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
102     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
103 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
104 schoenebeck 2953 - Implemented built-in script function "change_attack()".
105     - Implemented built-in script function "change_decay()".
106     - Implemented built-in script function "change_release()".
107 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
108     synthesis parameter changes immediately in case the respective note
109     was triggered at the same time, instead of scheduling the parameter
110     change, especially because it would cause some parameter types's
111     changes either to be ramped (i.e. change_vol()) or other types even
112     to have not effect at all (i.e. change_attack()).
113 schoenebeck 2965 - Implemented built-in script function "sh_left()".
114     - Implemented built-in script function "sh_right()".
115 schoenebeck 2970 - Implemented built-in script function "min()".
116     - Implemented built-in script function "max()".
117 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
118     was loaded.
119     - NKSP built-in wait() script function: abort script execution if
120     a negative or zero wait time was passed as argument (since this is
121     a common indication of a bug either of the script or even of the
122     engine, which could lead to RT instability or even worse).
123 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
124     threatening scripts.

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

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

259     - added a fine-tuned v1 envelope generator instead of using the
260     one from the gig engine
261 persson 2058 - fixed memory leak and memory handling errors
262 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
263 persson 2058 - allow non-numerical key values ("C#4" for example)
264     - "key" opcode now sets pitch_keycenter too
265     - fixed error when unloading instrument with same sample used by
266     multiple regions

273 persson 2082 - added support for amp_veltrack and amp_velcurve_N
274     - fine-tuned the default velocity curve
275 persson 2086 - added support for transpose
276     - fixed crash when using sw_down/up
277     - improved logic for sw_lokey/hikey/up/down/last
278     - added more v1 aliases to parser
279 persson 2091 - reduced memory usage for sfz data
280 persson 2101 - RT-safeness: avoid malloc in audio thread
281     - fixed a bug that could cause voice stealing to fail
282 persson 2106 - optimized sample lookup
283 persson 2114 - improved support for exclusive groups (group, off_by and

695     - optimized the SynchronizedConfig class so it doesn't wait
696     unnecessarily long after an update
697 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
698     events (e.g. to highlight the pressed keys on the virtual keyboard
699     of gigedit)
700 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
701 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
702 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
703     is only used by very few systems, most pick the int math
704     implementation, which is usually faster)
705 persson 1748 - fixes for audio drivers with varying buffer sizes
706 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
707     VST plugin
708 iliev 1789 - notification events for stream/voice count statistics are now sent
709     only when there are actual changes
710 persson 1790 - added memory ordering constraints to improve stability on
711     multi-core and multi-cpu systems
712 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
713 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
714 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
715     be switched on by command line option "--stacktrace" (the automatic
716     stacktrace mechanism seems to be broken on most systems at the moment)
717 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
718     a pointer to the launched InstrumentEditor object
719 schoenebeck 1876 - added optional 3rd party user data parameter for following
720     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
721     InstrumentEditor::Launch(),
722     InstrumentManager::LaunchInstrumentEditor()
723 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
724     model more strictly
725 persson 1895 - fixes for using large audio device buffers
726 persson 1951 - Windows: add the installation directory to the DLL search path
727     when loading an editor plugin (solves problems with VST and
728     gigedit on systems with other GTK versions installed)
729 schoenebeck 2509 - updated linuxsampler man page
730 schoenebeck 1601
731 schoenebeck 1599 * audio driver:
732     - removed the nonsense audio channel constraint (which was hard coded to
733     max. 100 audio channels) for most audio drivers
734 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
735     opposed to the LSCP specs
736 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
737     reflected the wrong value
738 persson 1644 - fixed a memory management bug in ASIO driver
739 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
740 persson 1777 - JACK: use jack_client_open instead of the deprecated
741 persson 1748 jack_client_new
742 iliev 1829 - added (experimental) CoreAudio driver
743 persson 1888 - applied old fixes to the ASIO driver that were included in the
744     previous binary release but accidentally never committed to CVS
745     (fixes #117)
746 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
747     win64)
748 persson 1895 - VST: added support for sample rate and buffer size changes
749     - VST: close editor (Fantasia) when the VST is removed

754     stereo
755 persson 1922 - added channel routing, fxsends and midi maps to the settings
756     stored in the plugin state
757 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
758     AudioChannel::CopyTo() methods using GCC vector exensions
759     (if available)
760 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
761     exception when getting parameters from a disconnected device
762 schoenebeck 1599
763 persson 1651 * MIDI driver:
764     - added JACK MIDI driver
765 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
766     want to (mis)use it for some purpose ("fixed" in all current MIDI
767     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
768 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
769 persson 1887 CoreMidi or AU
770 persson 1889 - fixed mingw-w64 compilation error in MME driver
771 persson 1924 - made program change handling in MIDI thread real-time safe by
772     moving the logic to a non-RT thread
773 persson 1951 - fixed minor memory leak in ALSA driver
774 persson 1651
775 schoenebeck 1604 * instruments database:
776 iliev 1603 - avoid time consuming samples scanning when adding instruments
777     to the instruments database
778 iliev 1727 - added support for handling lost files in the instruments database
779 iliev 1781 - Implemented option for adding instruments in separate directories
780     in the instruments database
781     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
782 persson 1908 - work-around for missing fnmatch function on Windows to make
783     instrument database compilable
784 schoenebeck 1930 - added instrument database support on Windows
785     works with both standalone mode and VST plugin.
786     the instruments DB file is located in
787     %USERPROFILE%\.linuxsampler\instruments.db which allows different
788     databases for each windows user
789     if no DB is present it automatically creates the .linuxsampler subdir
790     and then creates an empty DB
791 persson 1943 - fixed recursive import, which was broken on Windows
792 iliev 1603
793 persson 1644 * Gigasampler format engine:
794     - fixed a memory leak that could happen when a channel was deleted
795     while notes were playing
796 persson 1646 - made it possible to load an instrument even if the audio thread
797     isn't running
798 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
799     enough for piano gigs with pedal noise samples
800 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
801     respective FX send MIDI controller was used
802 schoenebeck 1724 - added support for GM global device volume SysEx message
803 schoenebeck 1762 (can be selected at compile time to either apply globally to the
804     whole sampler [default] or only to the sampler channels that are
805     connected to the respective MIDI input port the SysEx message arrived
806     on)
807 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
808     sometimes wrongly killed in the same buffer, causing no sound to
809     be played
810 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
811     which is usally used to switch a part between chromatic sounds and
812     drumkit sounds (as opposed to their common default setting of MIDI
813     part 10 being a drumkit part and all other ones chromatic parts), in
814     LS however one can switch between the first 16 MIDI instrument maps
815     defined for the sampler
816 persson 1764 - made it possible to create multiple sample channels even if the
817     audio thread isn't running
818 persson 1844 - fixed crash when removing channel with active voices (#116)
819 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
820     un-cache the respective sample if it's really not used by any
821     sampler engine anymore
822     - re-cache samples in case they were changed by an instrument editor,
823     e.g. when a sample was added while playing (#82)
824 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
825     same time stamp as the voice's note-on event and occured both in the
826     same audio fragment cycle (fixes bug #112)
827 persson 1858 - added support for the "fine tune" and "pitch bend range"
828     instrument-level gig parameters
829     - fixed minor artifacts in pitch bend handling
830 schoenebeck 1860 - added support for GS Reset SysEx message
831 persson 1862 - allow gig files to use unlimited downward pitch shifting
832     - added a limit check for upward pitch shifting
833 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
834     note was silent
835 persson 1923 - fixed crash happening when a pitch bend event arrived at the
836     same time a new instrument was loading
837 persson 1644
838 schoenebeck 1687 * LSCP server:
839     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
840     react on MIDI data arriving on certain sampler channels (so far only
841     Note-On and Note-Off events are sent via this LSCP event)
842 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
843     react on MIDI data arriving on certain MIDI input devices (so far only
844     Note-On and Note-Off events are sent via this LSCP event)
845 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
846     SET DB_INSTRUMENT FILE_PATH
847 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
848     frontends to send MIDI messages to specific sampler channel
849     - added two additional fields to GET FILE INSTRUMENT INFO command -
850     KEY_BINDINGS and KEYSWITCH_BINDINGS
851 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
852     was incorrect
853 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
854 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
855     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
856     be triggered respectively
857     - added new LSCP command "SET STREAMS" to globally alter the maximum
858     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
859     which will be triggered respectively
860 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
861     a gigedit file dialog is opened)
862 iliev 1848 - close all connections when LSCPServer is deleted
863 iliev 1882 - hard close of all sockets on exit
864 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
865     driver
866 schoenebeck 1687
867 iliev 1761 * Bug fixes:
868     - fixed a crash which occurs when removing a sampler channel waiting
869     to start instrument loading after another channel
870 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
871     instrument loading in progress (bug #113)
872 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
873     instrument with PERSISTENT load mode
874 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
875     - fixed memory leaks when issuing the following LSCP commands:
876     GET AUDIO_OUTPUT_DRIVER INFO
877     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
878     GET MIDI_INPUT_DRIVER INFO
879     GET MIDI_INPUT_DRIVER_PARAMETER INFO
880     - fixed possible compilation error when sqlite is not present
881 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
882 iliev 1847 - fixed crash when changing the audio output device of a sampler
883     channel with loaded instrument and start playing notes
884 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
885 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
886     PowerPC, which probably could cause crashes on that platform
887 persson 1889 - fixed a memory management error which could cause a crash when a
888     plugin was unloaded
889 persson 1896 - bugfix: two private structs had the same name, which could cause
890     problems if the linker chose the wrong constructor
891 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
892     Windows
893 iliev 1761
894    
895 schoenebeck 1560 Version 0.5.1 (6 December 2007)
896 schoenebeck 1454
897     * packaging changes:
898     - added autoconf checks for pthread library
899     - added autoconf check for pthread bug found on certain NPTL-enabled
900     glibc versions (see Gentoo bug report #194076)
901 senoner 1502 - added autoconf checks for MS Windows
902 schoenebeck 1454
903 persson 1455 * general changes:
904     - bugfix: the thread used by an editor plugin didn't die when the
905     editor closed
906 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
907     out all the space. operator--() did not apply size_mask after
908     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
909     order to avoid problems with the _NonVolatileReader functions.
910     - bugfix: Stream.h: added a missing divide by BytesPerSample in
911     GetWriteSpace(). Since this function is currently only used in
912     the stream's qsort() compare function, it didn't trigger any
913     bugs.
914     - Resampler.h, Synthesizer.h: cubic interpolation now works in
915     24bit mode too. Faster method to read 24bit words on little
916     endian machines (x86): replaced 3 byte reads + shifts with a 1
917     unaligned 32bit read and shift
918     - experimental support for MS Windows (MIDI input via MME, AUDIO
919     output via ASIO)
920     - made handling of SIGINT signal (Ctrl-C) a bit more robust
921 iliev 1541 - support for monitoring the total number of active disk streams
922     (new LSCP commands: GET TOTAL_STREAM_COUNT,
923     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
924 persson 1455
925 senoner 1500 * AUDIO driver:
926 persson 1534 - added Windows ASIO low latency audio driver
927 senoner 1500
928 senoner 1485 * MIDI driver:
929 schoenebeck 1495 - added MME Windows MIDI driver
930 senoner 1485
931 schoenebeck 1471 * LSCP server:
932     - added support for Windows style path / filenames, however with
933     forward slash path separators instead of backslash
934     (i.e. "C:/foo/bar.gig")
935 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
936     apostrophes as well
937 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
938     "LIST FILE INSTRUMENTS <file>" and
939     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
940     about an arbitrary instrument file on the system where the sampler is
941     running on
942 schoenebeck 1471
943 schoenebeck 1424 Version 0.5.0 (15 October 2007)
944 schoenebeck 947
945 schoenebeck 1065 * packaging changes:
946 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
947     API header files anymore
948 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
949     the Doxygen API documentation (explicitly listed in Doxyfile.in)
950 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
951     capable to execute our autoconf environment, thus no need anymore
952     to maintain the compile time configuration file (osx/version.h) for
953     OSX manually (patch by Toshi Nagata)
954 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
955     parameters
956 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
957     C++ API header files, all implementation internal global definitions
958     are now in global_private.h
959     - atomic.h is not exposed to the C++ API anymore
960     - no need to include config.h anymore for using LS's API header files
961     - fixed warnings in API doc generation
962 schoenebeck 1065
963 schoenebeck 947 * general changes:
964     - replaced the old, confusing MIDI program change mechanism by a
965     flexible MIDI instrument mapper which allows to map arbitrary
966 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
967 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
968     loaded on the respective channel when such MIDI program change
969     messages arrive, beside that, each entry allows to define a life-time
970     strategy for the instrument, so the user can define whether the
971     instrument should i.e. be permanently loaded (to be able to switch
972     quickly among sounds) or i.e. loaded just on demand when the
973     respective program change arrives (to safe RAM space), as well as a
974     global volume factor for each entry, so the user can adjust the volume
975     dynamic of his mapped instrument collection without having to modify
976 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
977     MIDI instrument maps and assign each sampler channel individually
978     a certain map, so that i.e. separation of normal instruments and
979     drumkits is possible
980 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
981     MIDI instrument maps, MIDI instruments, FX sends, global volume.
982 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
983     due to a constant size RingBuffer FIFO which is now replaced by a
984     dynamic (unlimited) size std::list FIFO
985 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
986     output channels for being processed by external effect processors
987     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
988     controllers
989 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
990 iliev 1130 - Implemented new, improved notification system
991 schoenebeck 1149 - fixed compilation errors regarding OSX
992     (patch by Toshi Nagata)
993 iliev 1161 - implemented instruments database
994 iliev 1345 - added support for escape sequences to the instruments database
995 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
996     within the sampler's process (by using instrument editor plugins),
997     you'll notice the new "Registered instrument editors:" message on
998 schoenebeck 1407 startup, added a new LSCP command:
999     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1000 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1001     given sampler channel, the plugin path can be overridden at compile
1002     time with ./configure --enable-plugin-dir=/some/dir
1003 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1004     in the sampler's process to safely edit instruments while playing
1005     without a crash (hopefully) by either suspending single regions
1006     wherever possible or if unavoidable whole engine(s)
1007 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1008     policy and priority on thread level, set a minimum stack size for
1009     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1010     threads simply inherited properties of starting thread instead of
1011     setting their own policy and priority
1012 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1013     main process did not wait for the stack trace process to finish
1014     its output
1015 persson 1248 - fixed some minor memory leaks
1016 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1017     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1018 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1019     register, to avoid relocations in the text segment at runtime)
1020 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1021 schoenebeck 947
1022     * MIDI driver:
1023     - dispatch bank select (MSB and LSB) messages
1024    
1025 schoenebeck 1049 * audio driver:
1026     - the ALSA audio output driver parameters now reflect the correct
1027     parameter value ranges for the respective selected sound card
1028     (patch by Till Wimmer, a bit fixed and extended)
1029    
1030 persson 951 * Gigasampler format engine:
1031     - if a filter is used and EG2 finishes before EG1, let the voice
1032     die when EG2 has finished (this fixes a problem with clicks and
1033     voice starvation for some gigs)
1034 persson 1038 - playback is no longer disabled during instrument loading
1035     - all notes playing on a channel that changes its instrument keep
1036     playing with the old instrument until they get a note off
1037     command
1038 persson 1039 - EG fix: a release value of zero could cause noises or crash
1039 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1040 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1041     above max sustain level, which means that there is a decay phase
1042     even if sustain is 100%
1043 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1044     noises or crashes
1045 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1046 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1047     supplied to the configure script (fixes #46)
1048 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1049     instead of a fix value
1050 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1051     127 (solo mode) only kill voices if the respective mode really
1052     changed
1053 persson 951
1054 schoenebeck 1244 * LSCP server:
1055     - fixed compile time error for old Bison versions
1056     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1057 schoenebeck 1245 - parser now supports extended ASCII character set
1058     (up to ASCII code 255, i.e. includes now umlauts and accents)
1059     - filename arguments in LSCP commands now allow to use escape
1060     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1061     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1062     code value like \xf2) (fixes bug #24)
1063 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1064     least one of their text-based parameters (i.e. name, description):
1065     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1066     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1067     "SET DB_INSTRUMENT_DIRECTORY NAME",
1068     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1069     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1070     "FIND DB_INSTRUMENT_DIRECTORIES"
1071 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1072     occured, the unexpected character and the actually expected, possible
1073     character(s), the latter only if less than 5 possibilities)
1074 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1075     settings
1076 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1077     of strings were treated as being one string containing commas
1078     (fixes #57)
1079 schoenebeck 1244
1080 iliev 959 * Bug fixes:
1081     - fixed crash occurring on certain LSCP scripts (Bug 39)
1082 persson 1038 - another thread safety fix for lscp "load engine" and "set
1083     channel audio output device"
1084 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1085     on a sampler channel with connected MIDI device
1086 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1087     device connected to a sampler channel to number less then or equal
1088     to the index of the port to which the sampler channel is connected.
1089 iliev 1296 - The previous bindings were not been disconnected when altering
1090     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1091     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1092 iliev 1297 - The active stream/voice count statistic was incorrect.
1093 iliev 1298 - notification events were not been sent for some sampler
1094     channel changes
1095 iliev 1305 - added default min and max values to restrict the number of allowed
1096     audio output channels and MIDI input ports
1097 iliev 1306 - the connection to the PCM interface is now closed when destroying
1098     an audio output device
1099 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1100 iliev 959
1101 schoenebeck 1221 * test cases:
1102     - updated and fixed (haven't been touched in a while)
1103    
1104 schoenebeck 937 Version 0.4.0 (24 November 2006)
1105 persson 696
1106 schoenebeck 697 * packaging changes:
1107 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1108     to post-(un)install steps; added devel package for liblinuxsampler;
1109     to linuxsampler.spec (RPM)
1110 schoenebeck 697 - install necessary development header files for allowing 3rd party
1111     applications to link against liblinuxsampler
1112     - liblinuxsampler's API documentation can be generated with 'make docs'
1113     (Doxygen required)
1114 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1115     implementation (currently either an integer math solution or a
1116     di-harmonic approximation), automatic detection can be overriden
1117     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1118     configure script argument though (mandatory for cross-compilation)
1119 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1120     provided some on his own (as CXXFLAGS)
1121 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1122     messages
1123 schoenebeck 852 - added compile time options to allow disabling the various audio and
1124     MIDI drivers
1125 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1126     (patch by Ebrahim Mayat)
1127 schoenebeck 697
1128 persson 696 * Gigasampler format engine:
1129 schoenebeck 738 - extensive synthesis optimization
1130     (reimplementation of EGs and LFO(s), removed synthesis parameter
1131     prerendering and the synthesis parameter matrix in general, splitting
1132     each audio fragment into subfragments now where each subfragment uses
1133 persson 830 constant pitch and filter coefficients. The volume coefficient is
1134     linearly interpolated inside a subfragment, unless
1135     --disable-interpolate-volume is set.)
1136 persson 696 - fine tuning of the EG modulation parameters
1137 persson 729 - improved filter cutoff calculation by adding support for the
1138     following gig parameters: Cutoff freq (used when no cutoff
1139     controller is defined), Control invert, Minimum cutoff, Velocity
1140 persson 791 curve and Velocity range. The keyboard tracking now scales
1141     cutoff frequency instead of resonance.
1142 persson 877 - added support for gig parameter Resonance.
1143 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1144 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1145     which can be overridden with --enable-global-attenuation
1146 persson 783 - EG fixes: made the length of "attack hold" stage more
1147     accurate. Release stage can now start before attack stage
1148 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1149     time now has a minimal value to prevent clicks.
1150 persson 799 - fixed pitch changes larger than one octave
1151 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1152     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1153     all modes can be altered via standard GM messages, that is CC5 for
1154     altering portamento time, CC65 for enabling / disabling portamento
1155     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1156 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1157     parameter) and crossfade
1158 persson 831 - added support for the "attenuation controller threshold" gig
1159     parameter
1160 persson 832 - added smoothing of volume changes caused by control change
1161     messages
1162 persson 865 - sample loop parameters are now taken from the DimensionRegion
1163     instead of the wave chunk
1164     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1165     not equal to a power of two
1166 persson 877 - reimplementation of the filter algorithm. The new filter is more
1167     accurate and supports all gig filter types, including bandreject
1168     and lowpass turbo.
1169 persson 903 - real support for 24 bit samples - samples are not truncated to
1170     16 bits anymore
1171     - support for aftertouch (channel pressure, not polyphonic
1172     aftertouch)
1173 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1174     amplifying from 0)
1175 persson 696
1176 schoenebeck 711 * LSCP server:
1177     - fixed application exit on broken pipe error (fixes bug #20)
1178 iliev 793 - fixed the notification messages delay due to lack of
1179     network activity (fixes bug #26)
1180 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1181     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1182 schoenebeck 711
1183 schoenebeck 838 * audio driver:
1184     - added aRts audio output driver (by no means RT safe)
1185    
1186 schoenebeck 775 * MIDI driver:
1187     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1188     messages several times instead of once
1189 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1190     for events (i.e. for offline rendering based MIDI drivers)
1191 persson 922 - added checks for bad MIDI data
1192 schoenebeck 775
1193 schoenebeck 900 * linuxsampler application:
1194     - show available sampler engine types on startup
1195    
1196 schoenebeck 705 * general changes:
1197     - support for muting sampler channels and solo mode of the same, two new
1198     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1199     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1200     introduced for this, the behavior is the same like on a mixer console
1201 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1202     --enable-process-muted-channels which can be used to enable the
1203     processing of muted channels.
1204 iliev 777 - support for sostenuto pedal
1205 iliev 779 - support for monitoring the total number of active voices
1206 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1207     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1208 persson 835 - fixed some memory management errors
1209 persson 841 - fixed some concurrency problems that could lead to crashes when
1210     LSCP commands were executed
1211 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1212     sampler channel (fixes bug #36)
1213 schoenebeck 705
1214 schoenebeck 692 Version 0.3.3 (15 July 2005)
1215 schoenebeck 686
1216     * packaging changes:
1217     - fixed compilation with gcc 4.0
1218    
1219 schoenebeck 687 * Gigasampler format engine:
1220     - LFO preprocessing was performed even though the respective LFO was
1221     disabled by the instrument patch (minor efficiency fix)
1222 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1223     for volume ramp downs in the same fragment (needed for current voice
1224     stealing implementation) then simply inform the user with a warning
1225     about possible click sounds and reduce the volume ramp down
1226     appropriately instead of cancelling the audio device connection
1227 schoenebeck 687
1228 schoenebeck 677 Version 0.3.2 (24 June 2005)
1229 schoenebeck 609
1230     * packaging changes:
1231     - updated autotools build files to compile on OS X
1232     (conditional compilation of CoreMIDI and MidiShare drivers)
1233 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1234     './configure --disable-asm' (definitely not recommended)
1235 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1236     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1237     (due to 'dist-bzip2' automake option)
1238 schoenebeck 649
1239     * Gigasampler format engine:
1240     - support for the gig parameters for "release velocity response" curves
1241     - fine tuning of the EGADSR envelope
1242     - volume of release triggered samples now depends on note-on velocity,
1243     note length and gig parameter "release trigger decay" instead of
1244     note-off velocity.
1245 schoenebeck 663 - revised voice stealing
1246     (fixes crash and endless loop caused by voice stealing)
1247 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1248 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1249     instead of when the respective voice is actually launched
1250     (fixes undefined behavior if stolen voices belonged to a key group -
1251     this case was followed by a "killed voice survived" error message)
1252 schoenebeck 669 - fixed minor issue with null/silence samples
1253     (those stole voices even though they don't need a voice at all which
1254     resulted in "voice stealing didn't work out" messages)
1255 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1256     instrument or audio output device change
1257 schoenebeck 654
1258 schoenebeck 620 * LSCP server:
1259 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1260 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1261 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1262 schoenebeck 609
1263 schoenebeck 668 * linuxsampler application:
1264     - added command line parameters --lscp-addr and --lscp-port to override
1265     default IP address and port of LSCP server
1266    
1267 schoenebeck 579 Version 0.3.1 (24 May 2005)
1268    
1269     * initial release
