* NKSP: Built-in "ignore_event()" function: argument is now optional,
  like with built-in function "ignore_controller()".

1 persson 2837 Version SVN trunk (?)
2    
3 persson 2856 * SFZ format engine:
4     - added support for <global>, <master> and #define (patch by Alby M)
5 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
6     - Added support for sfz extension opcode 'script' which may be used to
7     load real-time instrument script file (NKSP script language).
8 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
10 persson 2856
11 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
12 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
13     cutoff settings.
14    
15 persson 2837 * general changes:
16     - fixed printf type errors (mostly in debug messages)
17 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
18 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
19     allowing to sort data efficiently in real-time safe manner.
20     - RTList class: added methods for moving/inserting elements to arbitrary
21     position within a list.
22     - RTList class: added method fromPtr() for creating an Iterator object from
23     a raw element pointer.
24     - Attempt to partly fix resetting engine channels vs. resetting engine, an
25     overall cleanup of the Reset*(), ConnectAudioDevice(),
26     DisconnectAudioDevice() API methods would still be desirable though,
27     because the current situation is still inconsistent and error prone.
28 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
29     being directly assigned to a keyboard key. This allows more fine graded
30     processing of voices, which is i.e. required for certain instrument
31     script features.
32 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
33     (CC #64) events.
34     - Fix: Release trigger voices can now also distinguish correctly between
35     note-off and sustain pedal up events.
36 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
37     (while slow rate of crossfade smoother is preserved) to allow quick
38     volume and pan changes by instrument scripts for instance.
39 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
40     properly and thus were ignored for certain uses.
41 schoenebeck 3018 - Added new C++ API method
42     VirtualMidiDevice::SendChannelPressureToSampler().
43 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
44     sub threads is 16-byte aligned
45 schoenebeck 3054 - fixed numerous compiler warnings
46 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
47 persson 2837
48 schoenebeck 2866 * packaging changes:
49     - removed unnecessary dependency to libuuid
50     (originated by libgig's usage of it)
51 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
52     auto detect whether it (sh/c)ould output its messages in color.
53 schoenebeck 2866
54 schoenebeck 2871 * Real-time instrument scripts:
55     - Implemented scheduler for delayed MIDI events and for suspended scripts.
56     - Built-in script function "wait()": implemented support for function's
57     "duration-us" argument, thus scripts using this function are now
58     correctly resumed after the requested amount of microseconds.
59     - Built-in script function "play_note()": implemented support for
60     function's "duration-us" argument, thus notes triggered with this
61     argument are now correctly released after the requested amount of
62     microseconds.
63     - Fix: script events were not cleared when engine channel was reset,
64     potentially causing undefined behavior.
65     - Fixed crash which happened when trying to reference an undeclared
66     variable.
67 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
68     special value -1 for "duration-us" argument, which will cause the
69     triggered note to be released once the original note was released.
70 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
71     - Added new API method ScriptVM::syntaxHighlighting() which provides
72     a convenient syntax highlighting backend for external instrument
73     script editor applications.
74 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
75     - Extended parser issues to provide not only first line and first
76     column, but also last line and last column of issue (thus marking
77     the precise span of the issue within the source code).
78 schoenebeck 2902 - Reload script automatically after being modified by an instrument
79     editor.
80 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
81     like "on note end on".

87     - Implemented built-in script function "event_status()".
88     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
89     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
90     "event_status()" function.
91     - NKSP language: Added support for bitwise operators ".or.", ".and."
92     and ".not.".
93     - NKSP language scanner: Fixed IDs matching to require at least one
94     character (i.e. when matching function names or variable names).
95     - NKSP language scanner: disabled unusued rules.
96 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
97     be distinguished engine internally from "real" MIDI note on/off
98     events in order to avoid misbehaviors like hanging notes.
99 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
100     - Implemented built-in script variable "$NKSP_REAL_TIMER".
101     - Implemented built-in script variable "$NKSP_PERF_TIMER".
102     - Implemented built-in script variable "$ENGINE_UPTIME".
103 schoenebeck 2945 - Implemented built-in script function "inc()".
104     - Implemented built-in script function "dec()".
105     - NKSP language fix: division expressions were evaluated too often.
106     - NKSP language fix: string concatenation operator was right
107     associative instead of left (to right).
108 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
109     (i.e. "if end if").
110 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
111     - Implemented built-in script variable "$NI_CALLBACK_ID".
112     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
113     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
114     - Added support for read-only built-in variables (respectively
115     handled by the script parser).
116     - Added built-in script constant "$NI_CB_TYPE_INIT".
117     - Added built-in script constant "$NI_CB_TYPE_NOTE".
118     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
119     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
120 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
121 schoenebeck 2953 - Implemented built-in script function "change_attack()".
122     - Implemented built-in script function "change_decay()".
123     - Implemented built-in script function "change_release()".
124 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
125     synthesis parameter changes immediately in case the respective note
126     was triggered at the same time, instead of scheduling the parameter
127     change, especially because it would cause some parameter types's
128     changes either to be ramped (i.e. change_vol()) or other types even
129     to have not effect at all (i.e. change_attack()).
130 schoenebeck 2965 - Implemented built-in script function "sh_left()".
131     - Implemented built-in script function "sh_right()".
132 schoenebeck 2970 - Implemented built-in script function "min()".
133     - Implemented built-in script function "max()".
134 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
135     was loaded.
136     - NKSP built-in wait() script function: abort script execution if
137     a negative or zero wait time was passed as argument (since this is
138     a common indication of a bug either of the script or even of the
139     engine, which could lead to RT instability or even worse).
140 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
141     threatening scripts.
142 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
143 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
144     initializer list to an array variable.
145 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
146 schoenebeck 3076 - Implemented built-in script function "in_range()".
147 schoenebeck 3118 - Implemented built-in script function "change_amp_lfo_depth()".
148     - Implemented built-in script function "change_amp_lfo_freq()".
149     - Implemented built-in script function "change_pitch_lfo_depth()".
150     - Implemented built-in script function "change_pitch_lfo_freq()".
151 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
152     - Implemented built-in script function "change_tune_time()".
153     - Implemented built-in script function "fade_in()".
154     - Implemented built-in script function "fade_out()".
155     - Fixed acceptance of wrong data type of parameters passed to built-in
156     script functions "change_vol()", "change_tune()", "change_pan()",
157     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
158     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
159     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
160 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
161     of its possible parameter selections.
162     - Added built-in script function "set_event_par()" and implemented some
163     of its possible parameter selections.
164 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
165 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
166 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
167     built-in function "ignore_controller()".
168 schoenebeck 2871
169 schoenebeck 3050 * Instruments DB:
170     - Fixed memory access bug of general DB access code which lead to
171     undefined behavior.
172 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
173     - The instrument DB path of linuxsampler's --create-instruments-db argument
174     is now optional, if it is missing, then a default location is used.

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

217     in order to get rid of warnings from automake 1.14
218 persson 2382
219 persson 2086 * general changes:
220 iliev 2012 - Refactoring: moved the independent code from
221     the Gigasampler format engine to base classes
222 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
223     respective profiling code is currently broken
224 schoenebeck 2053 - Introduced support for optional environment variable
225     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
226     where the sampler shall look for instrument editor plugins
227     (patch by Luis Garrido, slightly modified).
228 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
229     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
230     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
231     note (in this implementation of the sampler its simply hard routed to
232     the 1st effect send of the sampler channel, no matter what the actual
233     effect type is)
234     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
235     note (in this implementation of the sampler its simply hard routed to
236     the 2nd effect send of the sampler channel, no matter what the actual
237     effect type is)
238 schoenebeck 2124 - implemented support for internal LADSPA effects
239 schoenebeck 2140 - raised limit of program change queue from 100 to 512
240     (as suggested by Alex Stone)

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

326 persson 2082 - added support for amp_veltrack and amp_velcurve_N
327     - fine-tuned the default velocity curve
328 persson 2086 - added support for transpose
329     - fixed crash when using sw_down/up
330     - improved logic for sw_lokey/hikey/up/down/last
331     - added more v1 aliases to parser
332 persson 2091 - reduced memory usage for sfz data
333 persson 2101 - RT-safeness: avoid malloc in audio thread
334     - fixed a bug that could cause voice stealing to fail
335 persson 2106 - optimized sample lookup
336 persson 2114 - improved support for exclusive groups (group, off_by and

342 persson 2167 - use loop markers from sample file if loop_start and loop_end are
343     not set in sfz file
344 persson 2175 - implemeted filters. Filter types: lowpass, bandpass, bandreject

712 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
713     (fixes #208)
714 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
715     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
716     practically irrelevant, however it caused problems with the new LSCP
717     shell's auto completion feature).
718 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
719     after each other (fixes #231).

722 schoenebeck 1599
723 schoenebeck 1639 * packaging changes:
724     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

756 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
757 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

768 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
769 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
770     be switched on by command line option "--stacktrace" (the automatic
771     stacktrace mechanism seems to be broken on most systems at the moment)
772 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
773     a pointer to the launched InstrumentEditor object
774 schoenebeck 1876 - added optional 3rd party user data parameter for following
775     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
776     InstrumentEditor::Launch(),

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

789 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
790     opposed to the LSCP specs
791 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
792     reflected the wrong value
793 persson 1644 - fixed a memory management bug in ASIO driver
794 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
795 persson 1777 - JACK: use jack_client_open instead of the deprecated
796 persson 1748 jack_client_new
797 iliev 1829 - added (experimental) CoreAudio driver
798 persson 1888 - applied old fixes to the ASIO driver that were included in the
799     previous binary release but accidentally never committed to CVS
800     (fixes #117)
801 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
802     win64)
803 persson 1895 - VST: added support for sample rate and buffer size changes
804     - VST: close editor (Fantasia) when the VST is removed

810 persson 1922 - added channel routing, fxsends and midi maps to the settings
811     stored in the plugin state
812 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
813     AudioChannel::CopyTo() methods using GCC vector exensions
814     (if available)
815 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
816     exception when getting parameters from a disconnected device
817 schoenebeck 1599
818 persson 1651 * MIDI driver:
819     - added JACK MIDI driver
820 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
821     want to (mis)use it for some purpose ("fixed" in all current MIDI
822     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
823 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
824 persson 1887 CoreMidi or AU
825 persson 1889 - fixed mingw-w64 compilation error in MME driver
826 persson 1924 - made program change handling in MIDI thread real-time safe by
827     moving the logic to a non-RT thread
828 persson 1951 - fixed minor memory leak in ALSA driver
829 persson 1651
830 schoenebeck 1604 * instruments database:
831 iliev 1603 - avoid time consuming samples scanning when adding instruments
832     to the instruments database
833 iliev 1727 - added support for handling lost files in the instruments database
834 iliev 1781 - Implemented option for adding instruments in separate directories
835     in the instruments database
836     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
837 persson 1908 - work-around for missing fnmatch function on Windows to make
838     instrument database compilable
839 schoenebeck 1930 - added instrument database support on Windows
840     works with both standalone mode and VST plugin.
841     the instruments DB file is located in
842     %USERPROFILE%\.linuxsampler\instruments.db which allows different
843     databases for each windows user
844     if no DB is present it automatically creates the .linuxsampler subdir
845     and then creates an empty DB
846 persson 1943 - fixed recursive import, which was broken on Windows
847 iliev 1603
848 persson 1644 * Gigasampler format engine:
849     - fixed a memory leak that could happen when a channel was deleted
850     while notes were playing
851 persson 1646 - made it possible to load an instrument even if the audio thread
852     isn't running
853 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
854     enough for piano gigs with pedal noise samples
855 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
856     respective FX send MIDI controller was used
857 schoenebeck 1724 - added support for GM global device volume SysEx message
858 schoenebeck 1762 (can be selected at compile time to either apply globally to the
859     whole sampler [default] or only to the sampler channels that are
860     connected to the respective MIDI input port the SysEx message arrived
861     on)
862 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
863     sometimes wrongly killed in the same buffer, causing no sound to
864     be played
865 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
866     which is usally used to switch a part between chromatic sounds and
867     drumkit sounds (as opposed to their common default setting of MIDI
868     part 10 being a drumkit part and all other ones chromatic parts), in
869     LS however one can switch between the first 16 MIDI instrument maps
870     defined for the sampler
871 persson 1764 - made it possible to create multiple sample channels even if the
872     audio thread isn't running
873 persson 1844 - fixed crash when removing channel with active voices (#116)
874 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
875     un-cache the respective sample if it's really not used by any
876     sampler engine anymore
877     - re-cache samples in case they were changed by an instrument editor,
878     e.g. when a sample was added while playing (#82)
879 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
880     same time stamp as the voice's note-on event and occured both in the
881     same audio fragment cycle (fixes bug #112)
882 persson 1858 - added support for the "fine tune" and "pitch bend range"
883     instrument-level gig parameters
884     - fixed minor artifacts in pitch bend handling
885 schoenebeck 1860 - added support for GS Reset SysEx message
886 persson 1862 - allow gig files to use unlimited downward pitch shifting
887     - added a limit check for upward pitch shifting
888 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
889     note was silent
890 persson 1923 - fixed crash happening when a pitch bend event arrived at the
891     same time a new instrument was loading
892 persson 1644
893 schoenebeck 1687 * LSCP server:
894     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
895     react on MIDI data arriving on certain sampler channels (so far only
896     Note-On and Note-Off events are sent via this LSCP event)
897 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
898     react on MIDI data arriving on certain MIDI input devices (so far only
899     Note-On and Note-Off events are sent via this LSCP event)
900 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
901     SET DB_INSTRUMENT FILE_PATH
902 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
903     frontends to send MIDI messages to specific sampler channel
904     - added two additional fields to GET FILE INSTRUMENT INFO command -
905     KEY_BINDINGS and KEYSWITCH_BINDINGS
906 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
907     was incorrect
908 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
909 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
910     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
911     be triggered respectively
912     - added new LSCP command "SET STREAMS" to globally alter the maximum
913     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
914     which will be triggered respectively
915 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
916     a gigedit file dialog is opened)
917 iliev 1848 - close all connections when LSCPServer is deleted
918 iliev 1882 - hard close of all sockets on exit
919 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
920     driver
921 schoenebeck 1687
922 iliev 1761 * Bug fixes:
923     - fixed a crash which occurs when removing a sampler channel waiting
924     to start instrument loading after another channel
925 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
926     instrument loading in progress (bug #113)
927 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
928     instrument with PERSISTENT load mode
929 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
930     - fixed memory leaks when issuing the following LSCP commands:
931     GET AUDIO_OUTPUT_DRIVER INFO
932     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
933     GET MIDI_INPUT_DRIVER INFO
934     GET MIDI_INPUT_DRIVER_PARAMETER INFO
935     - fixed possible compilation error when sqlite is not present
936 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
937 iliev 1847 - fixed crash when changing the audio output device of a sampler
938     channel with loaded instrument and start playing notes
939 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
940 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
941     PowerPC, which probably could cause crashes on that platform
942 persson 1889 - fixed a memory management error which could cause a crash when a
943     plugin was unloaded
944 persson 1896 - bugfix: two private structs had the same name, which could cause
945     problems if the linker chose the wrong constructor
946 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
947     Windows
948 iliev 1761
949    
950 schoenebeck 1560 Version 0.5.1 (6 December 2007)
951 schoenebeck 1454
952     * packaging changes:
953     - added autoconf checks for pthread library
954     - added autoconf check for pthread bug found on certain NPTL-enabled
955     glibc versions (see Gentoo bug report #194076)
956 senoner 1502 - added autoconf checks for MS Windows
957 schoenebeck 1454
958 persson 1455 * general changes:
959     - bugfix: the thread used by an editor plugin didn't die when the
960     editor closed
961 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
962     out all the space. operator--() did not apply size_mask after
963     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
964     order to avoid problems with the _NonVolatileReader functions.
965     - bugfix: Stream.h: added a missing divide by BytesPerSample in
966     GetWriteSpace(). Since this function is currently only used in
967     the stream's qsort() compare function, it didn't trigger any
968     bugs.
969     - Resampler.h, Synthesizer.h: cubic interpolation now works in
970     24bit mode too. Faster method to read 24bit words on little
971     endian machines (x86): replaced 3 byte reads + shifts with a 1
972     unaligned 32bit read and shift
973     - experimental support for MS Windows (MIDI input via MME, AUDIO
974     output via ASIO)
975     - made handling of SIGINT signal (Ctrl-C) a bit more robust
976 iliev 1541 - support for monitoring the total number of active disk streams
977     (new LSCP commands: GET TOTAL_STREAM_COUNT,
978     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
979 persson 1455
980 senoner 1500 * AUDIO driver:
981 persson 1534 - added Windows ASIO low latency audio driver
982 senoner 1500
983 senoner 1485 * MIDI driver:
984 schoenebeck 1495 - added MME Windows MIDI driver
985 senoner 1485
986 schoenebeck 1471 * LSCP server:
987     - added support for Windows style path / filenames, however with
988     forward slash path separators instead of backslash
989     (i.e. "C:/foo/bar.gig")
990 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
991     apostrophes as well
992 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
993     "LIST FILE INSTRUMENTS <file>" and
994     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
995     about an arbitrary instrument file on the system where the sampler is
996     running on
997 schoenebeck 1471
998 schoenebeck 1424 Version 0.5.0 (15 October 2007)
999 schoenebeck 947
1000 schoenebeck 1065 * packaging changes:
1001 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1002     API header files anymore
1003 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1004     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1005 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1006     capable to execute our autoconf environment, thus no need anymore
1007     to maintain the compile time configuration file (osx/version.h) for
1008     OSX manually (patch by Toshi Nagata)
1009 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1010     parameters
1011 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1012     C++ API header files, all implementation internal global definitions
1013     are now in global_private.h
1014     - atomic.h is not exposed to the C++ API anymore
1015     - no need to include config.h anymore for using LS's API header files
1016     - fixed warnings in API doc generation
1017 schoenebeck 1065
1018 schoenebeck 947 * general changes:
1019     - replaced the old, confusing MIDI program change mechanism by a
1020     flexible MIDI instrument mapper which allows to map arbitrary
1021 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1022 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1023     loaded on the respective channel when such MIDI program change
1024     messages arrive, beside that, each entry allows to define a life-time
1025     strategy for the instrument, so the user can define whether the
1026     instrument should i.e. be permanently loaded (to be able to switch
1027     quickly among sounds) or i.e. loaded just on demand when the
1028     respective program change arrives (to safe RAM space), as well as a
1029     global volume factor for each entry, so the user can adjust the volume
1030     dynamic of his mapped instrument collection without having to modify
1031 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1032     MIDI instrument maps and assign each sampler channel individually
1033     a certain map, so that i.e. separation of normal instruments and
1034     drumkits is possible
1035 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1036     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1037 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1038     due to a constant size RingBuffer FIFO which is now replaced by a
1039     dynamic (unlimited) size std::list FIFO
1040 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1041     output channels for being processed by external effect processors
1042     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1043     controllers
1044 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1045 iliev 1130 - Implemented new, improved notification system
1046 schoenebeck 1149 - fixed compilation errors regarding OSX
1047     (patch by Toshi Nagata)
1048 iliev 1161 - implemented instruments database
1049 iliev 1345 - added support for escape sequences to the instruments database
1050 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1051     within the sampler's process (by using instrument editor plugins),
1052     you'll notice the new "Registered instrument editors:" message on
1053 schoenebeck 1407 startup, added a new LSCP command:
1054     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1055 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1056     given sampler channel, the plugin path can be overridden at compile
1057     time with ./configure --enable-plugin-dir=/some/dir
1058 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1059     in the sampler's process to safely edit instruments while playing
1060     without a crash (hopefully) by either suspending single regions
1061     wherever possible or if unavoidable whole engine(s)
1062 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1063     policy and priority on thread level, set a minimum stack size for
1064     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1065     threads simply inherited properties of starting thread instead of
1066     setting their own policy and priority
1067 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1068     main process did not wait for the stack trace process to finish
1069     its output
1070 persson 1248 - fixed some minor memory leaks
1071 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1072     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1073 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1074     register, to avoid relocations in the text segment at runtime)
1075 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1076 schoenebeck 947
1077     * MIDI driver:
1078     - dispatch bank select (MSB and LSB) messages
1079    
1080 schoenebeck 1049 * audio driver:
1081     - the ALSA audio output driver parameters now reflect the correct
1082     parameter value ranges for the respective selected sound card
1083     (patch by Till Wimmer, a bit fixed and extended)
1084    
1085 persson 951 * Gigasampler format engine:
1086     - if a filter is used and EG2 finishes before EG1, let the voice
1087     die when EG2 has finished (this fixes a problem with clicks and
1088     voice starvation for some gigs)
1089 persson 1038 - playback is no longer disabled during instrument loading
1090     - all notes playing on a channel that changes its instrument keep
1091     playing with the old instrument until they get a note off
1092     command
1093 persson 1039 - EG fix: a release value of zero could cause noises or crash
1094 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1095 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1096     above max sustain level, which means that there is a decay phase
1097     even if sustain is 100%
1098 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1099     noises or crashes
1100 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1101 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1102     supplied to the configure script (fixes #46)
1103 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1104     instead of a fix value
1105 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1106     127 (solo mode) only kill voices if the respective mode really
1107     changed
1108 persson 951
1109 schoenebeck 1244 * LSCP server:
1110     - fixed compile time error for old Bison versions
1111     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1112 schoenebeck 1245 - parser now supports extended ASCII character set
1113     (up to ASCII code 255, i.e. includes now umlauts and accents)
1114     - filename arguments in LSCP commands now allow to use escape
1115     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1116     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1117     code value like \xf2) (fixes bug #24)
1118 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1119     least one of their text-based parameters (i.e. name, description):
1120     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1121     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1122     "SET DB_INSTRUMENT_DIRECTORY NAME",
1123     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1124     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1125     "FIND DB_INSTRUMENT_DIRECTORIES"
1126 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1127     occured, the unexpected character and the actually expected, possible
1128     character(s), the latter only if less than 5 possibilities)
1129 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1130     settings
1131 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1132     of strings were treated as being one string containing commas
1133     (fixes #57)
1134 schoenebeck 1244
1135 iliev 959 * Bug fixes:
1136     - fixed crash occurring on certain LSCP scripts (Bug 39)
1137 persson 1038 - another thread safety fix for lscp "load engine" and "set
1138     channel audio output device"
1139 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1140     on a sampler channel with connected MIDI device
1141 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1142     device connected to a sampler channel to number less then or equal
1143     to the index of the port to which the sampler channel is connected.
1144 iliev 1296 - The previous bindings were not been disconnected when altering
1145     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1146     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1147 iliev 1297 - The active stream/voice count statistic was incorrect.
1148 iliev 1298 - notification events were not been sent for some sampler
1149     channel changes
1150 iliev 1305 - added default min and max values to restrict the number of allowed
1151     audio output channels and MIDI input ports
1152 iliev 1306 - the connection to the PCM interface is now closed when destroying
1153     an audio output device
1154 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1155 iliev 959
1156 schoenebeck 1221 * test cases:
1157     - updated and fixed (haven't been touched in a while)
1158    
1159 schoenebeck 937 Version 0.4.0 (24 November 2006)
1160 persson 696
1161 schoenebeck 697 * packaging changes:
1162 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1163     to post-(un)install steps; added devel package for liblinuxsampler;
1164     to linuxsampler.spec (RPM)
1165 schoenebeck 697 - install necessary development header files for allowing 3rd party
1166     applications to link against liblinuxsampler
1167     - liblinuxsampler's API documentation can be generated with 'make docs'
1168     (Doxygen required)
1169 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1170     implementation (currently either an integer math solution or a
1171     di-harmonic approximation), automatic detection can be overriden
1172     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1173     configure script argument though (mandatory for cross-compilation)
1174 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1175     provided some on his own (as CXXFLAGS)
1176 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1177     messages
1178 schoenebeck 852 - added compile time options to allow disabling the various audio and
1179     MIDI drivers
1180 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1181     (patch by Ebrahim Mayat)
1182 schoenebeck 697
1183 persson 696 * Gigasampler format engine:
1184 schoenebeck 738 - extensive synthesis optimization
1185     (reimplementation of EGs and LFO(s), removed synthesis parameter
1186     prerendering and the synthesis parameter matrix in general, splitting
1187     each audio fragment into subfragments now where each subfragment uses
1188 persson 830 constant pitch and filter coefficients. The volume coefficient is
1189     linearly interpolated inside a subfragment, unless
1190     --disable-interpolate-volume is set.)
1191 persson 696 - fine tuning of the EG modulation parameters
1192 persson 729 - improved filter cutoff calculation by adding support for the
1193     following gig parameters: Cutoff freq (used when no cutoff
1194     controller is defined), Control invert, Minimum cutoff, Velocity
1195 persson 791 curve and Velocity range. The keyboard tracking now scales
1196     cutoff frequency instead of resonance.
1197 persson 877 - added support for gig parameter Resonance.
1198 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1199 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1200     which can be overridden with --enable-global-attenuation
1201 persson 783 - EG fixes: made the length of "attack hold" stage more
1202     accurate. Release stage can now start before attack stage
1203 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1204     time now has a minimal value to prevent clicks.
1205 persson 799 - fixed pitch changes larger than one octave
1206 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1207     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1208     all modes can be altered via standard GM messages, that is CC5 for
1209     altering portamento time, CC65 for enabling / disabling portamento
1210     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1211 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1212     parameter) and crossfade
1213 persson 831 - added support for the "attenuation controller threshold" gig
1214     parameter
1215 persson 832 - added smoothing of volume changes caused by control change
1216     messages
1217 persson 865 - sample loop parameters are now taken from the DimensionRegion
1218     instead of the wave chunk
1219     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1220     not equal to a power of two
1221 persson 877 - reimplementation of the filter algorithm. The new filter is more
1222     accurate and supports all gig filter types, including bandreject
1223     and lowpass turbo.
1224 persson 903 - real support for 24 bit samples - samples are not truncated to
1225     16 bits anymore
1226     - support for aftertouch (channel pressure, not polyphonic
1227     aftertouch)
1228 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1229     amplifying from 0)
1230 persson 696
1231 schoenebeck 711 * LSCP server:
1232     - fixed application exit on broken pipe error (fixes bug #20)
1233 iliev 793 - fixed the notification messages delay due to lack of
1234     network activity (fixes bug #26)
1235 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1236     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1237 schoenebeck 711
1238 schoenebeck 838 * audio driver:
1239     - added aRts audio output driver (by no means RT safe)
1240    
1241 schoenebeck 775 * MIDI driver:
1242     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1243     messages several times instead of once
1244 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1245     for events (i.e. for offline rendering based MIDI drivers)
1246 persson 922 - added checks for bad MIDI data
1247 schoenebeck 775
1248 schoenebeck 900 * linuxsampler application:
1249     - show available sampler engine types on startup
1250    
1251 schoenebeck 705 * general changes:
1252     - support for muting sampler channels and solo mode of the same, two new
1253     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1254     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1255     introduced for this, the behavior is the same like on a mixer console
1256 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1257     --enable-process-muted-channels which can be used to enable the
1258     processing of muted channels.
1259 iliev 777 - support for sostenuto pedal
1260 iliev 779 - support for monitoring the total number of active voices
1261 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1262     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1263 persson 835 - fixed some memory management errors
1264 persson 841 - fixed some concurrency problems that could lead to crashes when
1265     LSCP commands were executed
1266 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1267     sampler channel (fixes bug #36)
1268 schoenebeck 705
1269 schoenebeck 692 Version 0.3.3 (15 July 2005)
1270 schoenebeck 686
1271     * packaging changes:
1272     - fixed compilation with gcc 4.0
1273    
1274 schoenebeck 687 * Gigasampler format engine:
1275     - LFO preprocessing was performed even though the respective LFO was
1276     disabled by the instrument patch (minor efficiency fix)
1277 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1278     for volume ramp downs in the same fragment (needed for current voice
1279     stealing implementation) then simply inform the user with a warning
1280     about possible click sounds and reduce the volume ramp down
1281     appropriately instead of cancelling the audio device connection
1282 schoenebeck 687
1283 schoenebeck 677 Version 0.3.2 (24 June 2005)
1284 schoenebeck 609
1285     * packaging changes:
1286     - updated autotools build files to compile on OS X
1287     (conditional compilation of CoreMIDI and MidiShare drivers)
1288 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1289     './configure --disable-asm' (definitely not recommended)
1290 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1291     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1292     (due to 'dist-bzip2' automake option)
1293 schoenebeck 649
1294     * Gigasampler format engine:
1295     - support for the gig parameters for "release velocity response" curves
1296     - fine tuning of the EGADSR envelope
1297     - volume of release triggered samples now depends on note-on velocity,
1298     note length and gig parameter "release trigger decay" instead of
1299     note-off velocity.
1300 schoenebeck 663 - revised voice stealing
1301     (fixes crash and endless loop caused by voice stealing)
1302 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1303 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1304     instead of when the respective voice is actually launched
1305     (fixes undefined behavior if stolen voices belonged to a key group -
1306     this case was followed by a "killed voice survived" error message)
1307 schoenebeck 669 - fixed minor issue with null/silence samples
1308     (those stole voices even though they don't need a voice at all which
1309     resulted in "voice stealing didn't work out" messages)
1310 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1311     instrument or audio output device change
1312 schoenebeck 654
1313 schoenebeck 620 * LSCP server:
1314 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1315 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1316 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1317 schoenebeck 609
1318 schoenebeck 668 * linuxsampler application:
1319     - added command line parameters --lscp-addr and --lscp-port to override
1320     default IP address and port of LSCP server
1321    
1322 schoenebeck 579 Version 0.3.1 (24 May 2005)
1323    
1324     * initial release
