File size: 72262 byte(s)
* Implemented built-in script function "same_region()" (currently only
  available for gig format engine).
* Bumped version (2.0.0.svn53).

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 "$NKSP_IGNORE_WAIT".
114     - Added support for read-only built-in variables (respectively
115     handled by the script parser).
116     - Added built-in script constant "$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 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 2871
184 schoenebeck 3050 * Instruments DB:
185     - Fixed memory access bug of general DB access code which lead to
186     undefined behavior.
187 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
188     - The instrument DB path of linuxsampler's --create-instruments-db argument
189     is now optional, if it is missing, then a default location is used.
190 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
191     - Added support for scanning Sound Font (.sf2) files.
192 schoenebeck 3101 - Fixed undefined DB transaction behavior.

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

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

341 persson 2082 - added support for amp_veltrack and amp_velcurve_N
342     - fine-tuned the default velocity curve
343 persson 2086 - added support for transpose
344     - fixed crash when using sw_down/up
345     - improved logic for sw_lokey/hikey/up/down/last
346     - added more v1 aliases to parser
347 persson 2091 - reduced memory usage for sfz data

689     type while an instrument load was in progress
690 persson 2162 - bugfix: playing a note while changing the instrument could cause
691     a crash, or give "Handing back unknown region" error messages
692 persson 2165 - bugfix: calling SET VOICES (which Fantasia does on start and
693     refresh) could cause instruments to be unloaded
694 persson 2183 - Mac OS X: fixed name collision of enum in EffectControl and
695     wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
696 persson 2185 - Mac OS X: fixed hanging threads
697 persson 2187 - Windows: disabled the previous thread fix on non-Mac systems, as
698     it caused hanging threads on Windows
699 iliev 2201 - Fixed possible crashes due to corrupted MIDI/audio device list
700     after MIDI/audio device creation failure
701 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
702     instruments were uselessly precached with zero samples, however it still
703     took the full preloading time and on 1st program change the respective
704     instrument was completely reloaded again.
705 persson 2277 - fixed handling of rapid bank select and program change messages
706     sent to the same sampler channel (patch from the Open Octave
707     project, slightly adjusted)

722     playing a note in a key group
723 schoenebeck 2375 - fixed erroneous error message piping in VoiceBase.h
724     (labelled "Disk stream not available in time")
725 schoenebeck 2413 - Update effects on sample rate & period size changes (to avoid
726     crashes and noise on such transitions).
727 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
728     (fixes #208)
729 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
730     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
731     practically irrelevant, however it caused problems with the new LSCP
732     shell's auto completion feature).
733 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
734     after each other (fixes #231).

737 schoenebeck 1599
738 schoenebeck 1639 * packaging changes:
739     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

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

784 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
785     be switched on by command line option "--stacktrace" (the automatic
786     stacktrace mechanism seems to be broken on most systems at the moment)
787 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
788     a pointer to the launched InstrumentEditor object
789 schoenebeck 1876 - added optional 3rd party user data parameter for following
790     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

794     model more strictly
795 persson 1895 - fixes for using large audio device buffers
796 persson 1951 - Windows: add the installation directory to the DLL search path

807     reflected the wrong value
808 persson 1644 - fixed a memory management bug in ASIO driver
809 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

811 persson 1748 jack_client_new
812 iliev 1829 - added (experimental) CoreAudio driver
813 persson 1888 - applied old fixes to the ASIO driver that were included in the
814     previous binary release but accidentally never committed to CVS
815     (fixes #117)
816 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
817     win64)
818 persson 1895 - VST: added support for sample rate and buffer size changes
819     - VST: close editor (Fantasia) when the VST is removed

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

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