* Added new C++ API method
  VirtualMidiDevice::SendChannelPressureToSampler().
* Bumped version (2.0.0.svn30).

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 2837
35 schoenebeck 2866 * packaging changes:
36     - removed unnecessary dependency to libuuid
37     (originated by libgig's usage of it)
38 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
39     auto detect whether it (sh/c)ould output its messages in color.
40 schoenebeck 2866
41 schoenebeck 2871 * Real-time instrument scripts:
42     - Implemented scheduler for delayed MIDI events and for suspended scripts.
43     - Built-in script function "wait()": implemented support for function's
44     "duration-us" argument, thus scripts using this function are now
45     correctly resumed after the requested amount of microseconds.
46     - Built-in script function "play_note()": implemented support for
47     function's "duration-us" argument, thus notes triggered with this
48     argument are now correctly released after the requested amount of
49     microseconds.
50     - Fix: script events were not cleared when engine channel was reset,
51     potentially causing undefined behavior.
52     - Fixed crash which happened when trying to reference an undeclared
53     variable.
54 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
55     special value -1 for "duration-us" argument, which will cause the
56     triggered note to be released once the original note was released.
57 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
58     - Added new API method ScriptVM::syntaxHighlighting() which provides
59     a convenient syntax highlighting backend for external instrument
60     script editor applications.
61 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
62     - Extended parser issues to provide not only first line and first
63     column, but also last line and last column of issue (thus marking
64     the precise span of the issue within the source code).
65 schoenebeck 2902 - Reload script automatically after being modified by an instrument
66     editor.
67 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
68     like "on note end on".
69 schoenebeck 2931 - Implemented built-in script function "change_vol()".
70     - Implemented built-in script function "change_tune()".
71     - Implemented built-in script function "change_pan()".
72 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
73     - Implemented built-in script function "change_reso()".
74     - Implemented built-in script function "event_status()".
75     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
76     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
77     "event_status()" function.
78     - NKSP language: Added support for bitwise operators ".or.", ".and."
79     and ".not.".
80     - NKSP language scanner: Fixed IDs matching to require at least one
81     character (i.e. when matching function names or variable names).
82     - NKSP language scanner: disabled unusued rules.
83 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
84     be distinguished engine internally from "real" MIDI note on/off
85     events in order to avoid misbehaviors like hanging notes.
86 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
87     - Implemented built-in script variable "$NKSP_REAL_TIMER".
88     - Implemented built-in script variable "$NKSP_PERF_TIMER".
89     - Implemented built-in script variable "$ENGINE_UPTIME".
90 schoenebeck 2945 - Implemented built-in script function "inc()".
91     - Implemented built-in script function "dec()".
92     - NKSP language fix: division expressions were evaluated too often.
93     - NKSP language fix: string concatenation operator was right
94     associative instead of left (to right).
95 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
96     (i.e. "if end if").
97 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
98     - Implemented built-in script variable "$NI_CALLBACK_ID".
99     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
100     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
101     - Added support for read-only built-in variables (respectively
102     handled by the script parser).
103     - Added built-in script constant "$NI_CB_TYPE_INIT".
104     - Added built-in script constant "$NI_CB_TYPE_NOTE".
105     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
106     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
107 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
108 schoenebeck 2953 - Implemented built-in script function "change_attack()".
109     - Implemented built-in script function "change_decay()".
110     - Implemented built-in script function "change_release()".
111 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
112     synthesis parameter changes immediately in case the respective note
113     was triggered at the same time, instead of scheduling the parameter
114     change, especially because it would cause some parameter types's
115     changes either to be ramped (i.e. change_vol()) or other types even
116     to have not effect at all (i.e. change_attack()).
117 schoenebeck 2965 - Implemented built-in script function "sh_left()".
118     - Implemented built-in script function "sh_right()".
119 schoenebeck 2970 - Implemented built-in script function "min()".
120     - Implemented built-in script function "max()".
121 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
122     was loaded.
123     - NKSP built-in wait() script function: abort script execution if
124     a negative or zero wait time was passed as argument (since this is
125     a common indication of a bug either of the script or even of the
126     engine, which could lead to RT instability or even worse).
127 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
128     threatening scripts.
129 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
130 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
131     initializer list to an array variable.

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

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

266     - added a fine-tuned v1 envelope generator instead of using the
267     one from the gig engine
268 persson 2058 - fixed memory leak and memory handling errors
269 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
270 persson 2058 - allow non-numerical key values ("C#4" for example)

280 persson 2082 - added support for amp_veltrack and amp_velcurve_N
281     - fine-tuned the default velocity curve
282 persson 2086 - added support for transpose
283     - fixed crash when using sw_down/up
284     - improved logic for sw_lokey/hikey/up/down/last
285     - added more v1 aliases to parser
286 persson 2091 - reduced memory usage for sfz data
287 persson 2101 - RT-safeness: avoid malloc in audio thread

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

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

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

761     stereo
762 persson 1922 - added channel routing, fxsends and midi maps to the settings
763     stored in the plugin state
764 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
765     AudioChannel::CopyTo() methods using GCC vector exensions
766     (if available)
767 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
768     exception when getting parameters from a disconnected device
769 schoenebeck 1599
770 persson 1651 * MIDI driver:
771     - added JACK MIDI driver
772 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
773     want to (mis)use it for some purpose ("fixed" in all current MIDI
774     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
775 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
776 persson 1887 CoreMidi or AU
777 persson 1889 - fixed mingw-w64 compilation error in MME driver
778 persson 1924 - made program change handling in MIDI thread real-time safe by
779     moving the logic to a non-RT thread
780 persson 1951 - fixed minor memory leak in ALSA driver
781 persson 1651
782 schoenebeck 1604 * instruments database:
783 iliev 1603 - avoid time consuming samples scanning when adding instruments
784     to the instruments database
785 iliev 1727 - added support for handling lost files in the instruments database
786 iliev 1781 - Implemented option for adding instruments in separate directories
787     in the instruments database
788     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
789 persson 1908 - work-around for missing fnmatch function on Windows to make
790     instrument database compilable
791 schoenebeck 1930 - added instrument database support on Windows
792     works with both standalone mode and VST plugin.
793     the instruments DB file is located in
794     %USERPROFILE%\.linuxsampler\instruments.db which allows different
795     databases for each windows user
796     if no DB is present it automatically creates the .linuxsampler subdir
797     and then creates an empty DB
798 persson 1943 - fixed recursive import, which was broken on Windows
799 iliev 1603
800 persson 1644 * Gigasampler format engine:
801     - fixed a memory leak that could happen when a channel was deleted
802     while notes were playing
803 persson 1646 - made it possible to load an instrument even if the audio thread
804     isn't running
805 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
806     enough for piano gigs with pedal noise samples
807 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
808     respective FX send MIDI controller was used
809 schoenebeck 1724 - added support for GM global device volume SysEx message
810 schoenebeck 1762 (can be selected at compile time to either apply globally to the
811     whole sampler [default] or only to the sampler channels that are
812     connected to the respective MIDI input port the SysEx message arrived
813     on)
814 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
815     sometimes wrongly killed in the same buffer, causing no sound to
816     be played
817 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
818     which is usally used to switch a part between chromatic sounds and
819     drumkit sounds (as opposed to their common default setting of MIDI
820     part 10 being a drumkit part and all other ones chromatic parts), in
821     LS however one can switch between the first 16 MIDI instrument maps
822     defined for the sampler
823 persson 1764 - made it possible to create multiple sample channels even if the
824     audio thread isn't running
825 persson 1844 - fixed crash when removing channel with active voices (#116)
826 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
827     un-cache the respective sample if it's really not used by any
828     sampler engine anymore
829     - re-cache samples in case they were changed by an instrument editor,
830     e.g. when a sample was added while playing (#82)
831 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
832     same time stamp as the voice's note-on event and occured both in the
833     same audio fragment cycle (fixes bug #112)
834 persson 1858 - added support for the "fine tune" and "pitch bend range"
835     instrument-level gig parameters
836     - fixed minor artifacts in pitch bend handling
837 schoenebeck 1860 - added support for GS Reset SysEx message
838 persson 1862 - allow gig files to use unlimited downward pitch shifting
839     - added a limit check for upward pitch shifting
840 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
841     note was silent
842 persson 1923 - fixed crash happening when a pitch bend event arrived at the
843     same time a new instrument was loading
844 persson 1644
845 schoenebeck 1687 * LSCP server:
846     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
847     react on MIDI data arriving on certain sampler channels (so far only
848     Note-On and Note-Off events are sent via this LSCP event)
849 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
850     react on MIDI data arriving on certain MIDI input devices (so far only
851     Note-On and Note-Off events are sent via this LSCP event)
852 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
853     SET DB_INSTRUMENT FILE_PATH
854 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
855     frontends to send MIDI messages to specific sampler channel
856     - added two additional fields to GET FILE INSTRUMENT INFO command -
857     KEY_BINDINGS and KEYSWITCH_BINDINGS
858 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
859     was incorrect
860 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
861 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
862     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
863     be triggered respectively
864     - added new LSCP command "SET STREAMS" to globally alter the maximum
865     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
866     which will be triggered respectively
867 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
868     a gigedit file dialog is opened)
869 iliev 1848 - close all connections when LSCPServer is deleted
870 iliev 1882 - hard close of all sockets on exit
871 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
872     driver
873 schoenebeck 1687
874 iliev 1761 * Bug fixes:
875     - fixed a crash which occurs when removing a sampler channel waiting
876     to start instrument loading after another channel
877 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
878     instrument loading in progress (bug #113)
879 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
880     instrument with PERSISTENT load mode
881 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
882     - fixed memory leaks when issuing the following LSCP commands:
883     GET AUDIO_OUTPUT_DRIVER INFO
884     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
885     GET MIDI_INPUT_DRIVER INFO
886     GET MIDI_INPUT_DRIVER_PARAMETER INFO
887     - fixed possible compilation error when sqlite is not present
888 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
889 iliev 1847 - fixed crash when changing the audio output device of a sampler
890     channel with loaded instrument and start playing notes
891 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
892 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
893     PowerPC, which probably could cause crashes on that platform
894 persson 1889 - fixed a memory management error which could cause a crash when a
895     plugin was unloaded
896 persson 1896 - bugfix: two private structs had the same name, which could cause
897     problems if the linker chose the wrong constructor
898 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
899     Windows
900 iliev 1761
901    
902 schoenebeck 1560 Version 0.5.1 (6 December 2007)
903 schoenebeck 1454
904     * packaging changes:
905     - added autoconf checks for pthread library
906     - added autoconf check for pthread bug found on certain NPTL-enabled
907     glibc versions (see Gentoo bug report #194076)
908 senoner 1502 - added autoconf checks for MS Windows
909 schoenebeck 1454
910 persson 1455 * general changes:
911     - bugfix: the thread used by an editor plugin didn't die when the
912     editor closed
913 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
914     out all the space. operator--() did not apply size_mask after
915     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
916     order to avoid problems with the _NonVolatileReader functions.
917     - bugfix: Stream.h: added a missing divide by BytesPerSample in
918     GetWriteSpace(). Since this function is currently only used in
919     the stream's qsort() compare function, it didn't trigger any
920     bugs.
921     - Resampler.h, Synthesizer.h: cubic interpolation now works in
922     24bit mode too. Faster method to read 24bit words on little
923     endian machines (x86): replaced 3 byte reads + shifts with a 1
924     unaligned 32bit read and shift
925     - experimental support for MS Windows (MIDI input via MME, AUDIO
926     output via ASIO)
927     - made handling of SIGINT signal (Ctrl-C) a bit more robust
928 iliev 1541 - support for monitoring the total number of active disk streams
929     (new LSCP commands: GET TOTAL_STREAM_COUNT,
930     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
931 persson 1455
932 senoner 1500 * AUDIO driver:
933 persson 1534 - added Windows ASIO low latency audio driver
934 senoner 1500
935 senoner 1485 * MIDI driver:
936 schoenebeck 1495 - added MME Windows MIDI driver
937 senoner 1485
938 schoenebeck 1471 * LSCP server:
939     - added support for Windows style path / filenames, however with
940     forward slash path separators instead of backslash
941     (i.e. "C:/foo/bar.gig")
942 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
943     apostrophes as well
944 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
945     "LIST FILE INSTRUMENTS <file>" and
946     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
947     about an arbitrary instrument file on the system where the sampler is
948     running on
949 schoenebeck 1471
950 schoenebeck 1424 Version 0.5.0 (15 October 2007)
951 schoenebeck 947
952 schoenebeck 1065 * packaging changes:
953 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
954     API header files anymore
955 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
956     the Doxygen API documentation (explicitly listed in Doxyfile.in)
957 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
958     capable to execute our autoconf environment, thus no need anymore
959     to maintain the compile time configuration file (osx/version.h) for
960     OSX manually (patch by Toshi Nagata)
961 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
962     parameters
963 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
964     C++ API header files, all implementation internal global definitions
965     are now in global_private.h
966     - atomic.h is not exposed to the C++ API anymore
967     - no need to include config.h anymore for using LS's API header files
968     - fixed warnings in API doc generation
969 schoenebeck 1065
970 schoenebeck 947 * general changes:
971     - replaced the old, confusing MIDI program change mechanism by a
972     flexible MIDI instrument mapper which allows to map arbitrary
973 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
974 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
975     loaded on the respective channel when such MIDI program change
976     messages arrive, beside that, each entry allows to define a life-time
977     strategy for the instrument, so the user can define whether the
978     instrument should i.e. be permanently loaded (to be able to switch
979     quickly among sounds) or i.e. loaded just on demand when the
980     respective program change arrives (to safe RAM space), as well as a
981     global volume factor for each entry, so the user can adjust the volume
982     dynamic of his mapped instrument collection without having to modify
983 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
984     MIDI instrument maps and assign each sampler channel individually
985     a certain map, so that i.e. separation of normal instruments and
986     drumkits is possible
987 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
988     MIDI instrument maps, MIDI instruments, FX sends, global volume.
989 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
990     due to a constant size RingBuffer FIFO which is now replaced by a
991     dynamic (unlimited) size std::list FIFO
992 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
993     output channels for being processed by external effect processors
994     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
995     controllers
996 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
997 iliev 1130 - Implemented new, improved notification system
998 schoenebeck 1149 - fixed compilation errors regarding OSX
999     (patch by Toshi Nagata)
1000 iliev 1161 - implemented instruments database
1001 iliev 1345 - added support for escape sequences to the instruments database
1002 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1003     within the sampler's process (by using instrument editor plugins),
1004     you'll notice the new "Registered instrument editors:" message on
1005 schoenebeck 1407 startup, added a new LSCP command:
1006     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1007 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1008     given sampler channel, the plugin path can be overridden at compile
1009     time with ./configure --enable-plugin-dir=/some/dir
1010 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1011     in the sampler's process to safely edit instruments while playing
1012     without a crash (hopefully) by either suspending single regions
1013     wherever possible or if unavoidable whole engine(s)
1014 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1015     policy and priority on thread level, set a minimum stack size for
1016     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1017     threads simply inherited properties of starting thread instead of
1018     setting their own policy and priority
1019 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1020     main process did not wait for the stack trace process to finish
1021     its output
1022 persson 1248 - fixed some minor memory leaks
1023 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1024     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1025 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1026     register, to avoid relocations in the text segment at runtime)
1027 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1028 schoenebeck 947
1029     * MIDI driver:
1030     - dispatch bank select (MSB and LSB) messages
1031    
1032 schoenebeck 1049 * audio driver:
1033     - the ALSA audio output driver parameters now reflect the correct
1034     parameter value ranges for the respective selected sound card
1035     (patch by Till Wimmer, a bit fixed and extended)
1036    
1037 persson 951 * Gigasampler format engine:
1038     - if a filter is used and EG2 finishes before EG1, let the voice
1039     die when EG2 has finished (this fixes a problem with clicks and
1040     voice starvation for some gigs)
1041 persson 1038 - playback is no longer disabled during instrument loading
1042     - all notes playing on a channel that changes its instrument keep
1043     playing with the old instrument until they get a note off
1044     command
1045 persson 1039 - EG fix: a release value of zero could cause noises or crash
1046 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1047 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1048     above max sustain level, which means that there is a decay phase
1049     even if sustain is 100%
1050 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1051     noises or crashes
1052 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1053 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1054     supplied to the configure script (fixes #46)
1055 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1056     instead of a fix value
1057 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1058     127 (solo mode) only kill voices if the respective mode really
1059     changed
1060 persson 951
1061 schoenebeck 1244 * LSCP server:
1062     - fixed compile time error for old Bison versions
1063     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1064 schoenebeck 1245 - parser now supports extended ASCII character set
1065     (up to ASCII code 255, i.e. includes now umlauts and accents)
1066     - filename arguments in LSCP commands now allow to use escape
1067     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1068     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1069     code value like \xf2) (fixes bug #24)
1070 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1071     least one of their text-based parameters (i.e. name, description):
1072     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1073     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1074     "SET DB_INSTRUMENT_DIRECTORY NAME",
1075     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1076     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1077     "FIND DB_INSTRUMENT_DIRECTORIES"
1078 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1079     occured, the unexpected character and the actually expected, possible
1080     character(s), the latter only if less than 5 possibilities)
1081 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1082     settings
1083 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1084     of strings were treated as being one string containing commas
1085     (fixes #57)
1086 schoenebeck 1244
1087 iliev 959 * Bug fixes:
1088     - fixed crash occurring on certain LSCP scripts (Bug 39)
1089 persson 1038 - another thread safety fix for lscp "load engine" and "set
1090     channel audio output device"
1091 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1092     on a sampler channel with connected MIDI device
1093 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1094     device connected to a sampler channel to number less then or equal
1095     to the index of the port to which the sampler channel is connected.
1096 iliev 1296 - The previous bindings were not been disconnected when altering
1097     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1098     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1099 iliev 1297 - The active stream/voice count statistic was incorrect.
1100 iliev 1298 - notification events were not been sent for some sampler
1101     channel changes
1102 iliev 1305 - added default min and max values to restrict the number of allowed
1103     audio output channels and MIDI input ports
1104 iliev 1306 - the connection to the PCM interface is now closed when destroying
1105     an audio output device
1106 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1107 iliev 959
1108 schoenebeck 1221 * test cases:
1109     - updated and fixed (haven't been touched in a while)
1110    
1111 schoenebeck 937 Version 0.4.0 (24 November 2006)
1112 persson 696
1113 schoenebeck 697 * packaging changes:
1114 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1115     to post-(un)install steps; added devel package for liblinuxsampler;
1116     to linuxsampler.spec (RPM)
1117 schoenebeck 697 - install necessary development header files for allowing 3rd party
1118     applications to link against liblinuxsampler
1119     - liblinuxsampler's API documentation can be generated with 'make docs'
1120     (Doxygen required)
1121 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1122     implementation (currently either an integer math solution or a
1123     di-harmonic approximation), automatic detection can be overriden
1124     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1125     configure script argument though (mandatory for cross-compilation)
1126 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1127     provided some on his own (as CXXFLAGS)
1128 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1129     messages
1130 schoenebeck 852 - added compile time options to allow disabling the various audio and
1131     MIDI drivers
1132 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1133     (patch by Ebrahim Mayat)
1134 schoenebeck 697
1135 persson 696 * Gigasampler format engine:
1136 schoenebeck 738 - extensive synthesis optimization
1137     (reimplementation of EGs and LFO(s), removed synthesis parameter
1138     prerendering and the synthesis parameter matrix in general, splitting
1139     each audio fragment into subfragments now where each subfragment uses
1140 persson 830 constant pitch and filter coefficients. The volume coefficient is
1141     linearly interpolated inside a subfragment, unless
1142     --disable-interpolate-volume is set.)
1143 persson 696 - fine tuning of the EG modulation parameters
1144 persson 729 - improved filter cutoff calculation by adding support for the
1145     following gig parameters: Cutoff freq (used when no cutoff
1146     controller is defined), Control invert, Minimum cutoff, Velocity
1147 persson 791 curve and Velocity range. The keyboard tracking now scales
1148     cutoff frequency instead of resonance.
1149 persson 877 - added support for gig parameter Resonance.
1150 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1151 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1152     which can be overridden with --enable-global-attenuation
1153 persson 783 - EG fixes: made the length of "attack hold" stage more
1154     accurate. Release stage can now start before attack stage
1155 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1156     time now has a minimal value to prevent clicks.
1157 persson 799 - fixed pitch changes larger than one octave
1158 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1159     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1160     all modes can be altered via standard GM messages, that is CC5 for
1161     altering portamento time, CC65 for enabling / disabling portamento
1162     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1163 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1164     parameter) and crossfade
1165 persson 831 - added support for the "attenuation controller threshold" gig
1166     parameter
1167 persson 832 - added smoothing of volume changes caused by control change
1168     messages
1169 persson 865 - sample loop parameters are now taken from the DimensionRegion
1170     instead of the wave chunk
1171     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1172     not equal to a power of two
1173 persson 877 - reimplementation of the filter algorithm. The new filter is more
1174     accurate and supports all gig filter types, including bandreject
1175     and lowpass turbo.
1176 persson 903 - real support for 24 bit samples - samples are not truncated to
1177     16 bits anymore
1178     - support for aftertouch (channel pressure, not polyphonic
1179     aftertouch)
1180 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1181     amplifying from 0)
1182 persson 696
1183 schoenebeck 711 * LSCP server:
1184     - fixed application exit on broken pipe error (fixes bug #20)
1185 iliev 793 - fixed the notification messages delay due to lack of
1186     network activity (fixes bug #26)
1187 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1188     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1189 schoenebeck 711
1190 schoenebeck 838 * audio driver:
1191     - added aRts audio output driver (by no means RT safe)
1192    
1193 schoenebeck 775 * MIDI driver:
1194     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1195     messages several times instead of once
1196 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1197     for events (i.e. for offline rendering based MIDI drivers)
1198 persson 922 - added checks for bad MIDI data
1199 schoenebeck 775
1200 schoenebeck 900 * linuxsampler application:
1201     - show available sampler engine types on startup
1202    
1203 schoenebeck 705 * general changes:
1204     - support for muting sampler channels and solo mode of the same, two new
1205     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1206     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1207     introduced for this, the behavior is the same like on a mixer console
1208 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1209     --enable-process-muted-channels which can be used to enable the
1210     processing of muted channels.
1211 iliev 777 - support for sostenuto pedal
1212 iliev 779 - support for monitoring the total number of active voices
1213 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1214     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1215 persson 835 - fixed some memory management errors
1216 persson 841 - fixed some concurrency problems that could lead to crashes when
1217     LSCP commands were executed
1218 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1219     sampler channel (fixes bug #36)
1220 schoenebeck 705
1221 schoenebeck 692 Version 0.3.3 (15 July 2005)
1222 schoenebeck 686
1223     * packaging changes:
1224     - fixed compilation with gcc 4.0
1225    
1226 schoenebeck 687 * Gigasampler format engine:
1227     - LFO preprocessing was performed even though the respective LFO was
1228     disabled by the instrument patch (minor efficiency fix)
1229 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1230     for volume ramp downs in the same fragment (needed for current voice
1231     stealing implementation) then simply inform the user with a warning
1232     about possible click sounds and reduce the volume ramp down
1233     appropriately instead of cancelling the audio device connection
1234 schoenebeck 687
1235 schoenebeck 677 Version 0.3.2 (24 June 2005)
1236 schoenebeck 609
1237     * packaging changes:
1238     - updated autotools build files to compile on OS X
1239     (conditional compilation of CoreMIDI and MidiShare drivers)
1240 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1241     './configure --disable-asm' (definitely not recommended)
1242 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1243     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1244     (due to 'dist-bzip2' automake option)
1245 schoenebeck 649
1246     * Gigasampler format engine:
1247     - support for the gig parameters for "release velocity response" curves
1248     - fine tuning of the EGADSR envelope
1249     - volume of release triggered samples now depends on note-on velocity,
1250     note length and gig parameter "release trigger decay" instead of
1251     note-off velocity.
1252 schoenebeck 663 - revised voice stealing
1253     (fixes crash and endless loop caused by voice stealing)
1254 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1255 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1256     instead of when the respective voice is actually launched
1257     (fixes undefined behavior if stolen voices belonged to a key group -
1258     this case was followed by a "killed voice survived" error message)
1259 schoenebeck 669 - fixed minor issue with null/silence samples
1260     (those stole voices even though they don't need a voice at all which
1261     resulted in "voice stealing didn't work out" messages)
1262 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1263     instrument or audio output device change
1264 schoenebeck 654
1265 schoenebeck 620 * LSCP server:
1266 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1267 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1268 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1269 schoenebeck 609
1270 schoenebeck 668 * linuxsampler application:
1271     - added command line parameters --lscp-addr and --lscp-port to override
1272     default IP address and port of LSCP server
1273    
1274 schoenebeck 579 Version 0.3.1 (24 May 2005)
1275    
1276     * initial release
