* NKSP: built-in "play_note()" function now supports a sample playback
  start offset with argument 3, where special value -1 means to use the
  regular sample offset as defined by the instrument file.
* Bumped version (2.0.0.svn55).

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".
82 schoenebeck 2931 - Implemented built-in script function "change_vol()".
83     - Implemented built-in script function "change_tune()".
84     - Implemented built-in script function "change_pan()".
85 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
86     - Implemented built-in script function "change_reso()".
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

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".

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 3214 - Implemented built-in script function "change_velo()".
169     - Implemented built-in script function "change_note()".
170 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
171     intuitive behavior if used in combination with "change_vol_time()" or
172     "change_tune_time()" respectively: now tuning/volume changes are only
173     assigned (without delay) immediately to a new note if the respective
174     timing function has not been called before, otherwise the volume/tuning
175     changes are automatically faded (before, only the event's time stamp was
176     relevant).
177 schoenebeck 3221 - Implemented built-in script function "array_equal()".
178     - Implemented built-in script function "search()".
179     - Implemented built-in script function "sort()".
180     - NKSP Fix: Never suspend "init" event handlers.
181 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
182     available for gig format engine).
183 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
184     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
185     - Implemented built-in script function "change_vol_curve()".
186     - Implemented built-in script function "change_tune_curve()".
187 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
188     offset with argument 3, where special value -1 means to use the regular
189     sample offset as defined by the instrument file.
190 schoenebeck 2871
191 schoenebeck 3050 * Instruments DB:
192     - Fixed memory access bug of general DB access code which lead to
193     undefined behavior.
194 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
195     - The instrument DB path of linuxsampler's --create-instruments-db argument
196     is now optional, if it is missing, then a default location is used.
197 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
198     - Added support for scanning Sound Font (.sf2) files.
199 schoenebeck 3101 - Fixed undefined DB transaction behavior.

237 persson 2519 - enabled automake 'subdir-objects' option and moved external
238     source references (vst, au, asio) from makefiles to cpp files,
239     in order to get rid of warnings from automake 1.14
240 persson 2382
241 persson 2086 * general changes:
242 iliev 2012 - Refactoring: moved the independent code from
243     the Gigasampler format engine to base classes
244 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
245     respective profiling code is currently broken
246 schoenebeck 2053 - Introduced support for optional environment variable
247     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
248     where the sampler shall look for instrument editor plugins
249     (patch by Luis Garrido, slightly modified).
250 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
251     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
252     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
253     note (in this implementation of the sampler its simply hard routed to
254     the 1st effect send of the sampler channel, no matter what the actual
255     effect type is)
256     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
257     note (in this implementation of the sampler its simply hard routed to
258     the 2nd effect send of the sampler channel, no matter what the actual
259     effect type is)
260 schoenebeck 2124 - implemented support for internal LADSPA effects
261 schoenebeck 2140 - raised limit of program change queue from 100 to 512
262     (as suggested by Alex Stone)

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

349     - fine-tuned the default velocity curve
350 persson 2086 - added support for transpose
351     - fixed crash when using sw_down/up
352     - improved logic for sw_lokey/hikey/up/down/last
353     - added more v1 aliases to parser
354 persson 2091 - reduced memory usage for sfz data

693 iliev 2201 - fixed crash which occurred when changing an already deployed sampler
694 schoenebeck 2123 channel to a different engine type
695 persson 2127 - fixed crash when deleting a sampler channel or changing engine
696     type while an instrument load was in progress
697 persson 2162 - bugfix: playing a note while changing the instrument could cause
698     a crash, or give "Handing back unknown region" error messages

702     wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
703 persson 2185 - Mac OS X: fixed hanging threads

706 iliev 2201 - Fixed possible crashes due to corrupted MIDI/audio device list
707     after MIDI/audio device creation failure
708 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
709     instruments were uselessly precached with zero samples, however it still
710     took the full preloading time and on 1st program change the respective
711     instrument was completely reloaded again.
712 persson 2277 - fixed handling of rapid bank select and program change messages
713     sent to the same sampler channel (patch from the Open Octave
714     project, slightly adjusted)

731     (labelled "Disk stream not available in time")
732 schoenebeck 2413 - Update effects on sample rate & period size changes (to avoid
733     crashes and noise on such transitions).
734 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
735     (fixes #208)
736 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
737     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
738     practically irrelevant, however it caused problems with the new LSCP
739     shell's auto completion feature).
740 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
741     after each other (fixes #231).

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

791 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
792     be switched on by command line option "--stacktrace" (the automatic
793     stacktrace mechanism seems to be broken on most systems at the moment)
794 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
795     a pointer to the launched InstrumentEditor object
796 schoenebeck 1876 - added optional 3rd party user data parameter for following

818 persson 1748 jack_client_new
819 iliev 1829 - added (experimental) CoreAudio driver
820 persson 1888 - applied old fixes to the ASIO driver that were included in the
821     previous binary release but accidentally never committed to CVS
822     (fixes #117)
823 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
824     win64)
825 persson 1895 - VST: added support for sample rate and buffer size changes

833     stored in the plugin state
834 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
835     AudioChannel::CopyTo() methods using GCC vector exensions
836     (if available)
837 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
838     exception when getting parameters from a disconnected device
839 schoenebeck 1599
840 persson 1651 * MIDI driver:
841     - added JACK MIDI driver
842 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
843     want to (mis)use it for some purpose ("fixed" in all current MIDI
844     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
845 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
846 persson 1887 CoreMidi or AU
847 persson 1889 - fixed mingw-w64 compilation error in MME driver
848 persson 1924 - made program change handling in MIDI thread real-time safe by
849     moving the logic to a non-RT thread

859 persson 1908 - work-around for missing fnmatch function on Windows to make
860     instrument database compilable
861 schoenebeck 1930 - added instrument database support on Windows
862     works with both standalone mode and VST plugin.
863     the instruments DB file is located in
864     %USERPROFILE%\.linuxsampler\instruments.db which allows different
865     databases for each windows user
866     if no DB is present it automatically creates the .linuxsampler subdir
867     and then creates an empty DB
868 persson 1943 - fixed recursive import, which was broken on Windows
869 iliev 1603
870 persson 1644 * Gigasampler format engine:
871     - fixed a memory leak that could happen when a channel was deleted
872     while notes were playing
873 persson 1646 - made it possible to load an instrument even if the audio thread
874     isn't running
875 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
876     enough for piano gigs with pedal noise samples
877 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
878     respective FX send MIDI controller was used
879 schoenebeck 1724 - added support for GM global device volume SysEx message
880 schoenebeck 1762 (can be selected at compile time to either apply globally to the
881     whole sampler [default] or only to the sampler channels that are
882     connected to the respective MIDI input port the SysEx message arrived
883     on)
884 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
885     sometimes wrongly killed in the same buffer, causing no sound to
886     be played
887 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
888     which is usally used to switch a part between chromatic sounds and
889     drumkit sounds (as opposed to their common default setting of MIDI
890     part 10 being a drumkit part and all other ones chromatic parts), in
891     LS however one can switch between the first 16 MIDI instrument maps
892     defined for the sampler
893 persson 1764 - made it possible to create multiple sample channels even if the
894     audio thread isn't running
895 persson 1844 - fixed crash when removing channel with active voices (#116)
896 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
897     un-cache the respective sample if it's really not used by any
898     sampler engine anymore
899     - re-cache samples in case they were changed by an instrument editor,
900     e.g. when a sample was added while playing (#82)
901 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
902     same time stamp as the voice's note-on event and occured both in the
903     same audio fragment cycle (fixes bug #112)
904 persson 1858 - added support for the "fine tune" and "pitch bend range"
905     instrument-level gig parameters
906     - fixed minor artifacts in pitch bend handling
907 schoenebeck 1860 - added support for GS Reset SysEx message
908 persson 1862 - allow gig files to use unlimited downward pitch shifting
909     - added a limit check for upward pitch shifting
910 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
911     note was silent
912 persson 1923 - fixed crash happening when a pitch bend event arrived at the
913     same time a new instrument was loading
914 persson 1644
915 schoenebeck 1687 * LSCP server:
916     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
917     react on MIDI data arriving on certain sampler channels (so far only
918     Note-On and Note-Off events are sent via this LSCP event)
919 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
920     react on MIDI data arriving on certain MIDI input devices (so far only
921     Note-On and Note-Off events are sent via this LSCP event)
922 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
923     SET DB_INSTRUMENT FILE_PATH
924 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
925     frontends to send MIDI messages to specific sampler channel
926     - added two additional fields to GET FILE INSTRUMENT INFO command -
927     KEY_BINDINGS and KEYSWITCH_BINDINGS
928 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
929     was incorrect
930 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
931 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
932     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
933     be triggered respectively
934     - added new LSCP command "SET STREAMS" to globally alter the maximum
935     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
936     which will be triggered respectively
937 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
938     a gigedit file dialog is opened)
939 iliev 1848 - close all connections when LSCPServer is deleted
940 iliev 1882 - hard close of all sockets on exit
941 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
942     driver
943 schoenebeck 1687
944 iliev 1761 * Bug fixes:
945     - fixed a crash which occurs when removing a sampler channel waiting
946     to start instrument loading after another channel
947 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
948     instrument loading in progress (bug #113)
949 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
950     instrument with PERSISTENT load mode
951 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
952     - fixed memory leaks when issuing the following LSCP commands:
953     GET AUDIO_OUTPUT_DRIVER INFO
954     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
955     GET MIDI_INPUT_DRIVER INFO
956     GET MIDI_INPUT_DRIVER_PARAMETER INFO
957     - fixed possible compilation error when sqlite is not present
958 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
959 iliev 1847 - fixed crash when changing the audio output device of a sampler
960     channel with loaded instrument and start playing notes
961 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
962 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
963     PowerPC, which probably could cause crashes on that platform
964 persson 1889 - fixed a memory management error which could cause a crash when a
965     plugin was unloaded
966 persson 1896 - bugfix: two private structs had the same name, which could cause
967     problems if the linker chose the wrong constructor
968 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
969     Windows
970 iliev 1761
971    
972 schoenebeck 1560 Version 0.5.1 (6 December 2007)
973 schoenebeck 1454
974     * packaging changes:
975     - added autoconf checks for pthread library
976     - added autoconf check for pthread bug found on certain NPTL-enabled
977     glibc versions (see Gentoo bug report #194076)
978 senoner 1502 - added autoconf checks for MS Windows
979 schoenebeck 1454
980 persson 1455 * general changes:
981     - bugfix: the thread used by an editor plugin didn't die when the
982     editor closed
983 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
984     out all the space. operator--() did not apply size_mask after
985     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
986     order to avoid problems with the _NonVolatileReader functions.
987     - bugfix: Stream.h: added a missing divide by BytesPerSample in
988     GetWriteSpace(). Since this function is currently only used in
989     the stream's qsort() compare function, it didn't trigger any
990     bugs.
991     - Resampler.h, Synthesizer.h: cubic interpolation now works in
992     24bit mode too. Faster method to read 24bit words on little
993     endian machines (x86): replaced 3 byte reads + shifts with a 1
994     unaligned 32bit read and shift
995     - experimental support for MS Windows (MIDI input via MME, AUDIO
996     output via ASIO)
997     - made handling of SIGINT signal (Ctrl-C) a bit more robust
998 iliev 1541 - support for monitoring the total number of active disk streams
999     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1000     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1001 persson 1455
1002 senoner 1500 * AUDIO driver:
1003 persson 1534 - added Windows ASIO low latency audio driver
1004 senoner 1500
1005 senoner 1485 * MIDI driver:
1006 schoenebeck 1495 - added MME Windows MIDI driver
1007 senoner 1485
1008 schoenebeck 1471 * LSCP server:
1009     - added support for Windows style path / filenames, however with
1010     forward slash path separators instead of backslash
1011     (i.e. "C:/foo/bar.gig")
1012 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1013     apostrophes as well
1014 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1015     "LIST FILE INSTRUMENTS <file>" and
1016     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1017     about an arbitrary instrument file on the system where the sampler is
1018     running on
1019 schoenebeck 1471
1020 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1021 schoenebeck 947
1022 schoenebeck 1065 * packaging changes:
1023 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1024     API header files anymore
1025 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1026     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1027 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1028     capable to execute our autoconf environment, thus no need anymore
1029     to maintain the compile time configuration file (osx/version.h) for
1030     OSX manually (patch by Toshi Nagata)
1031 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1032     parameters
1033 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1034     C++ API header files, all implementation internal global definitions
1035     are now in global_private.h
1036     - atomic.h is not exposed to the C++ API anymore
1037     - no need to include config.h anymore for using LS's API header files
1038     - fixed warnings in API doc generation
1039 schoenebeck 1065
1040 schoenebeck 947 * general changes:
1041     - replaced the old, confusing MIDI program change mechanism by a
1042     flexible MIDI instrument mapper which allows to map arbitrary
1043 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1044 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1045     loaded on the respective channel when such MIDI program change
1046     messages arrive, beside that, each entry allows to define a life-time
1047     strategy for the instrument, so the user can define whether the
1048     instrument should i.e. be permanently loaded (to be able to switch
1049     quickly among sounds) or i.e. loaded just on demand when the
1050     respective program change arrives (to safe RAM space), as well as a
1051     global volume factor for each entry, so the user can adjust the volume
1052     dynamic of his mapped instrument collection without having to modify
1053 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1054     MIDI instrument maps and assign each sampler channel individually
1055     a certain map, so that i.e. separation of normal instruments and
1056     drumkits is possible
1057 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1058     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1059 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1060     due to a constant size RingBuffer FIFO which is now replaced by a
1061     dynamic (unlimited) size std::list FIFO
1062 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1063     output channels for being processed by external effect processors
1064     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1065     controllers
1066 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1067 iliev 1130 - Implemented new, improved notification system
1068 schoenebeck 1149 - fixed compilation errors regarding OSX
1069     (patch by Toshi Nagata)
1070 iliev 1161 - implemented instruments database
1071 iliev 1345 - added support for escape sequences to the instruments database
1072 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1073     within the sampler's process (by using instrument editor plugins),
1074     you'll notice the new "Registered instrument editors:" message on
1075 schoenebeck 1407 startup, added a new LSCP command:
1076     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1077 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1078     given sampler channel, the plugin path can be overridden at compile
1079     time with ./configure --enable-plugin-dir=/some/dir
1080 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1081     in the sampler's process to safely edit instruments while playing
1082     without a crash (hopefully) by either suspending single regions
1083     wherever possible or if unavoidable whole engine(s)
1084 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1085     policy and priority on thread level, set a minimum stack size for
1086     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1087     threads simply inherited properties of starting thread instead of
1088     setting their own policy and priority
1089 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1090     main process did not wait for the stack trace process to finish
1091     its output
1092 persson 1248 - fixed some minor memory leaks
1093 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1094     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1095 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1096     register, to avoid relocations in the text segment at runtime)
1097 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1098 schoenebeck 947
1099     * MIDI driver:
1100     - dispatch bank select (MSB and LSB) messages
1101    
1102 schoenebeck 1049 * audio driver:
1103     - the ALSA audio output driver parameters now reflect the correct
1104     parameter value ranges for the respective selected sound card
1105     (patch by Till Wimmer, a bit fixed and extended)
1106    
1107 persson 951 * Gigasampler format engine:
1108     - if a filter is used and EG2 finishes before EG1, let the voice
1109     die when EG2 has finished (this fixes a problem with clicks and
1110     voice starvation for some gigs)
1111 persson 1038 - playback is no longer disabled during instrument loading
1112     - all notes playing on a channel that changes its instrument keep
1113     playing with the old instrument until they get a note off
1114     command
1115 persson 1039 - EG fix: a release value of zero could cause noises or crash
1116 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1117 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1118     above max sustain level, which means that there is a decay phase
1119     even if sustain is 100%
1120 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1121     noises or crashes
1122 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1123 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1124     supplied to the configure script (fixes #46)
1125 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1126     instead of a fix value
1127 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1128     127 (solo mode) only kill voices if the respective mode really
1129     changed
1130 persson 951
1131 schoenebeck 1244 * LSCP server:
1132     - fixed compile time error for old Bison versions
1133     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1134 schoenebeck 1245 - parser now supports extended ASCII character set
1135     (up to ASCII code 255, i.e. includes now umlauts and accents)
1136     - filename arguments in LSCP commands now allow to use escape
1137     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1138     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1139     code value like \xf2) (fixes bug #24)
1140 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1141     least one of their text-based parameters (i.e. name, description):
1142     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1143     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1144     "SET DB_INSTRUMENT_DIRECTORY NAME",
1145     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1146     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1147     "FIND DB_INSTRUMENT_DIRECTORIES"
1148 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1149     occured, the unexpected character and the actually expected, possible
1150     character(s), the latter only if less than 5 possibilities)
1151 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1152     settings
1153 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1154     of strings were treated as being one string containing commas
1155     (fixes #57)
1156 schoenebeck 1244
1157 iliev 959 * Bug fixes:
1158     - fixed crash occurring on certain LSCP scripts (Bug 39)
1159 persson 1038 - another thread safety fix for lscp "load engine" and "set
1160     channel audio output device"
1161 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1162     on a sampler channel with connected MIDI device
1163 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1164     device connected to a sampler channel to number less then or equal
1165     to the index of the port to which the sampler channel is connected.
1166 iliev 1296 - The previous bindings were not been disconnected when altering
1167     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1168     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1169 iliev 1297 - The active stream/voice count statistic was incorrect.
1170 iliev 1298 - notification events were not been sent for some sampler
1171     channel changes
1172 iliev 1305 - added default min and max values to restrict the number of allowed
1173     audio output channels and MIDI input ports
1174 iliev 1306 - the connection to the PCM interface is now closed when destroying
1175     an audio output device
1176 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1177 iliev 959
1178 schoenebeck 1221 * test cases:
1179     - updated and fixed (haven't been touched in a while)
1180    
1181 schoenebeck 937 Version 0.4.0 (24 November 2006)
1182 persson 696
1183 schoenebeck 697 * packaging changes:
1184 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1185     to post-(un)install steps; added devel package for liblinuxsampler;
1186     to linuxsampler.spec (RPM)
1187 schoenebeck 697 - install necessary development header files for allowing 3rd party
1188     applications to link against liblinuxsampler
1189     - liblinuxsampler's API documentation can be generated with 'make docs'
1190     (Doxygen required)
1191 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1192     implementation (currently either an integer math solution or a
1193     di-harmonic approximation), automatic detection can be overriden
1194     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1195     configure script argument though (mandatory for cross-compilation)
1196 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1197     provided some on his own (as CXXFLAGS)
1198 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1199     messages
1200 schoenebeck 852 - added compile time options to allow disabling the various audio and
1201     MIDI drivers
1202 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1203     (patch by Ebrahim Mayat)
1204 schoenebeck 697
1205 persson 696 * Gigasampler format engine:
1206 schoenebeck 738 - extensive synthesis optimization
1207     (reimplementation of EGs and LFO(s), removed synthesis parameter
1208     prerendering and the synthesis parameter matrix in general, splitting
1209     each audio fragment into subfragments now where each subfragment uses
1210 persson 830 constant pitch and filter coefficients. The volume coefficient is
1211     linearly interpolated inside a subfragment, unless
1212     --disable-interpolate-volume is set.)
1213 persson 696 - fine tuning of the EG modulation parameters
1214 persson 729 - improved filter cutoff calculation by adding support for the
1215     following gig parameters: Cutoff freq (used when no cutoff
1216     controller is defined), Control invert, Minimum cutoff, Velocity
1217 persson 791 curve and Velocity range. The keyboard tracking now scales
1218     cutoff frequency instead of resonance.
1219 persson 877 - added support for gig parameter Resonance.
1220 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1221 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1222     which can be overridden with --enable-global-attenuation
1223 persson 783 - EG fixes: made the length of "attack hold" stage more
1224     accurate. Release stage can now start before attack stage
1225 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1226     time now has a minimal value to prevent clicks.
1227 persson 799 - fixed pitch changes larger than one octave
1228 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1229     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1230     all modes can be altered via standard GM messages, that is CC5 for
1231     altering portamento time, CC65 for enabling / disabling portamento
1232     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1233 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1234     parameter) and crossfade
1235 persson 831 - added support for the "attenuation controller threshold" gig
1236     parameter
1237 persson 832 - added smoothing of volume changes caused by control change
1238     messages
1239 persson 865 - sample loop parameters are now taken from the DimensionRegion
1240     instead of the wave chunk
1241     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1242     not equal to a power of two
1243 persson 877 - reimplementation of the filter algorithm. The new filter is more
1244     accurate and supports all gig filter types, including bandreject
1245     and lowpass turbo.
1246 persson 903 - real support for 24 bit samples - samples are not truncated to
1247     16 bits anymore
1248     - support for aftertouch (channel pressure, not polyphonic
1249     aftertouch)
1250 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1251     amplifying from 0)
1252 persson 696
1253 schoenebeck 711 * LSCP server:
1254     - fixed application exit on broken pipe error (fixes bug #20)
1255 iliev 793 - fixed the notification messages delay due to lack of
1256     network activity (fixes bug #26)
1257 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1258     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1259 schoenebeck 711
1260 schoenebeck 838 * audio driver:
1261     - added aRts audio output driver (by no means RT safe)
1262    
1263 schoenebeck 775 * MIDI driver:
1264     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1265     messages several times instead of once
1266 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1267     for events (i.e. for offline rendering based MIDI drivers)
1268 persson 922 - added checks for bad MIDI data
1269 schoenebeck 775
1270 schoenebeck 900 * linuxsampler application:
1271     - show available sampler engine types on startup
1272    
1273 schoenebeck 705 * general changes:
1274     - support for muting sampler channels and solo mode of the same, two new
1275     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1276     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1277     introduced for this, the behavior is the same like on a mixer console
1278 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1279     --enable-process-muted-channels which can be used to enable the
1280     processing of muted channels.
1281 iliev 777 - support for sostenuto pedal
1282 iliev 779 - support for monitoring the total number of active voices
1283 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1284     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1285 persson 835 - fixed some memory management errors
1286 persson 841 - fixed some concurrency problems that could lead to crashes when
1287     LSCP commands were executed
1288 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1289     sampler channel (fixes bug #36)
1290 schoenebeck 705
1291 schoenebeck 692 Version 0.3.3 (15 July 2005)
1292 schoenebeck 686
1293     * packaging changes:
1294     - fixed compilation with gcc 4.0
1295    
1296 schoenebeck 687 * Gigasampler format engine:
1297     - LFO preprocessing was performed even though the respective LFO was
1298     disabled by the instrument patch (minor efficiency fix)
1299 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1300     for volume ramp downs in the same fragment (needed for current voice
1301     stealing implementation) then simply inform the user with a warning
1302     about possible click sounds and reduce the volume ramp down
1303     appropriately instead of cancelling the audio device connection
1304 schoenebeck 687
1305 schoenebeck 677 Version 0.3.2 (24 June 2005)
1306 schoenebeck 609
1307     * packaging changes:
1308     - updated autotools build files to compile on OS X
1309     (conditional compilation of CoreMIDI and MidiShare drivers)
1310 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1311     './configure --disable-asm' (definitely not recommended)
1312 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1313     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1314     (due to 'dist-bzip2' automake option)
1315 schoenebeck 649
1316     * Gigasampler format engine:
1317     - support for the gig parameters for "release velocity response" curves
1318     - fine tuning of the EGADSR envelope
1319     - volume of release triggered samples now depends on note-on velocity,
1320     note length and gig parameter "release trigger decay" instead of
1321     note-off velocity.
1322 schoenebeck 663 - revised voice stealing
1323     (fixes crash and endless loop caused by voice stealing)
1324 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1325 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1326     instead of when the respective voice is actually launched
1327     (fixes undefined behavior if stolen voices belonged to a key group -
1328     this case was followed by a "killed voice survived" error message)
1329 schoenebeck 669 - fixed minor issue with null/silence samples
1330     (those stole voices even though they don't need a voice at all which
1331     resulted in "voice stealing didn't work out" messages)
1332 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1333     instrument or audio output device change
1334 schoenebeck 654
1335 schoenebeck 620 * LSCP server:
1336 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1337 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1338 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1339 schoenebeck 609
1340 schoenebeck 668 * linuxsampler application:
1341     - added command line parameters --lscp-addr and --lscp-port to override
1342     default IP address and port of LSCP server
1343    
1344 schoenebeck 579 Version 0.3.1 (24 May 2005)
1345    
1346     * initial release
