File size: 75777 byte(s)
* NKSP script editor API: Fixed app termination due to a lexer start
  condition stack underrun.
* NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
  USE_CODE_IF_NOT() preprocessor statements.
* Bumped version (2.0.0.svn70).

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 3291 - sfz parser: allow missing space between header and opcode
11 persson 2856
12 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
13 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
14     cutoff settings.
15 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
16     all if an up-pitch of more than 40 semi tones was requested (I don't
17     think there is any stock gig sound that requires this behavior to
18     resemble its original sound).
19 schoenebeck 3072
20 persson 2837 * general changes:
21     - fixed printf type errors (mostly in debug messages)
22 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
23 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
24     allowing to sort data efficiently in real-time safe manner.
25     - RTList class: added methods for moving/inserting elements to arbitrary
26     position within a list.
27     - RTList class: added method fromPtr() for creating an Iterator object from
28     a raw element pointer.
29     - Attempt to partly fix resetting engine channels vs. resetting engine, an
30     overall cleanup of the Reset*(), ConnectAudioDevice(),
31     DisconnectAudioDevice() API methods would still be desirable though,
32     because the current situation is still inconsistent and error prone.
33 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
34     being directly assigned to a keyboard key. This allows more fine graded
35     processing of voices, which is i.e. required for certain instrument
36     script features.
37 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
38     (CC #64) events.
39     - Fix: Release trigger voices can now also distinguish correctly between
40     note-off and sustain pedal up events.
41 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
42     (while slow rate of crossfade smoother is preserved) to allow quick
43     volume and pan changes by instrument scripts for instance.
44 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
45     properly and thus were ignored for certain uses.
46 schoenebeck 3018 - Added new C++ API method
47     VirtualMidiDevice::SendChannelPressureToSampler().
48 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
49     sub threads is 16-byte aligned
50 schoenebeck 3054 - fixed numerous compiler warnings
51 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
52 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
53     fixes potential undefined behavior.
54 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
55     have a valid sample mapped (fixes bug #252).
56     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
57 persson 2837
58 schoenebeck 2866 * packaging changes:
59     - removed unnecessary dependency to libuuid
60     (originated by libgig's usage of it)
61 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
62     auto detect whether it (sh/c)ould output its messages in color.
63 schoenebeck 2866
64 schoenebeck 2871 * Real-time instrument scripts:
65     - Implemented scheduler for delayed MIDI events and for suspended scripts.
66     - Built-in script function "wait()": implemented support for function's
67     "duration-us" argument, thus scripts using this function are now
68     correctly resumed after the requested amount of microseconds.
69     - Built-in script function "play_note()": implemented support for
70     function's "duration-us" argument, thus notes triggered with this
71     argument are now correctly released after the requested amount of
72     microseconds.
73     - Fix: script events were not cleared when engine channel was reset,
74     potentially causing undefined behavior.
75     - Fixed crash which happened when trying to reference an undeclared
76     variable.
77 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
78     special value -1 for "duration-us" argument, which will cause the
79     triggered note to be released once the original note was released.
80 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
81     - Added new API method ScriptVM::syntaxHighlighting() which provides
82     a convenient syntax highlighting backend for external instrument
83     script editor applications.
84 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
85     - Extended parser issues to provide not only first line and first
86     column, but also last line and last column of issue (thus marking
87     the precise span of the issue within the source code).
88 schoenebeck 2902 - Reload script automatically after being modified by an instrument
89     editor.
90 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
91     like "on note end on".
92 schoenebeck 2931 - Implemented built-in script function "change_vol()".
93     - Implemented built-in script function "change_tune()".
94     - Implemented built-in script function "change_pan()".

96     - Implemented built-in script function "change_reso()".
97     - Implemented built-in script function "event_status()".
98     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
99     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
100     "event_status()" function.
101     - NKSP language: Added support for bitwise operators ".or.", ".and."
102     and ".not.".
103     - NKSP language scanner: Fixed IDs matching to require at least one
104     character (i.e. when matching function names or variable names).
105     - NKSP language scanner: disabled unusued rules.
106 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
107     be distinguished engine internally from "real" MIDI note on/off
108     events in order to avoid misbehaviors like hanging notes.
109 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
110     - Implemented built-in script variable "$NKSP_REAL_TIMER".
111     - Implemented built-in script variable "$NKSP_PERF_TIMER".
112     - Implemented built-in script variable "$ENGINE_UPTIME".
113 schoenebeck 2945 - Implemented built-in script function "inc()".
114     - Implemented built-in script function "dec()".
115     - NKSP language fix: division expressions were evaluated too often.
116     - NKSP language fix: string concatenation operator was right
117     associative instead of left (to right).
118 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
119     (i.e. "if end if").
120 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
121     - Implemented built-in script variable "$NI_CALLBACK_ID".
122     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
123     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
124     - Added support for read-only built-in variables (respectively
125     handled by the script parser).
126     - Added built-in script constant "$NI_CB_TYPE_INIT".
127     - Added built-in script constant "$NI_CB_TYPE_NOTE".
128     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
129     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
130 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.

132     - Implemented built-in script function "change_decay()".
133     - Implemented built-in script function "change_release()".
134 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
135     synthesis parameter changes immediately in case the respective note
136     was triggered at the same time, instead of scheduling the parameter
137     change, especially because it would cause some parameter types's
138     changes either to be ramped (i.e. change_vol()) or other types even
139     to have not effect at all (i.e. change_attack()).
140 schoenebeck 2965 - Implemented built-in script function "sh_left()".
141     - Implemented built-in script function "sh_right()".
142 schoenebeck 2970 - Implemented built-in script function "min()".
143     - Implemented built-in script function "max()".
144 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
145     was loaded.
146     - NKSP built-in wait() script function: abort script execution if
147     a negative or zero wait time was passed as argument (since this is
148     a common indication of a bug either of the script or even of the
149     engine, which could lead to RT instability or even worse).
150 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
151     threatening scripts.
152 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
153 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
154     initializer list to an array variable.
155 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
156 schoenebeck 3076 - Implemented built-in script function "in_range()".

163     - Implemented built-in script function "fade_in()".
164     - Implemented built-in script function "fade_out()".
165     - Fixed acceptance of wrong data type of parameters passed to built-in
166     script functions "change_vol()", "change_tune()", "change_pan()",
167     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
168     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
169     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
170 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
171     of its possible parameter selections.
172     - Added built-in script function "set_event_par()" and implemented some
173     of its possible parameter selections.
174 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
175 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
176 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
177     built-in function "ignore_controller()".
178 schoenebeck 3214 - Implemented built-in script function "change_velo()".
179     - Implemented built-in script function "change_note()".
180 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
181     intuitive behavior if used in combination with "change_vol_time()" or
182     "change_tune_time()" respectively: now tuning/volume changes are only
183     assigned (without delay) immediately to a new note if the respective
184     timing function has not been called before, otherwise the volume/tuning
185     changes are automatically faded (before, only the event's time stamp was
186     relevant).
187 schoenebeck 3221 - Implemented built-in script function "array_equal()".
188     - Implemented built-in script function "search()".
189     - Implemented built-in script function "sort()".
190     - NKSP Fix: Never suspend "init" event handlers.
191 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
192     available for gig format engine).
193 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
194     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
195     - Implemented built-in script function "change_vol_curve()".
196     - Implemented built-in script function "change_tune_curve()".
197 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
198     offset with argument 3, where special value -1 means to use the regular
199     sample offset as defined by the instrument file.
200 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
201     - Built-in variable $EVENT_NOTE is now a read-only variable.
202     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
203     - built-in "play_note()" function now accepts -2 for its fourth argument
204     (note duration) which means the life time of the note shall be sticked
205     to the requested note number of argument 1.
206     - Fix: built-in "play_note()" function now returns 0 as result value if
207     -1 was passed for its fourth argument (note duration) and the respective
208     parent note is already gone.
209 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
210 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
211     - NKSP language: Raise parser warning if array variable is accessed with
212     an index that exceeds the array's size.
213 schoenebeck 3259 - NKSP language fix: Unknown characters were not handled correctly.
214 schoenebeck 3260 - NKSP language: Added support for "synchronized .. end synchronized"
215     code blocks.
216 schoenebeck 3277 - Implemented built-in script function "abort()" which allows to abort
217     another script handler by passing its callback ID.
218 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
219     "init" event handlers.
220 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
221     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
222     to retrieve all code blocks filtered out by the preprocessor.
223 schoenebeck 3293 - Added built-in script function "fork()".
224     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
225     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
226     - Fixed potential crash when accessing dynamic built-in array variables.
227 schoenebeck 3296 - Added built-in script function "callback_status()".
228     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
229     - Added built-in constant $CALLBACK_STATUS_QUEUE.
230     - Added built-in constant $CALLBACK_STATUS_RUNNING.
231 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
232     "change_decay()" and "change_release()" to i.e. allow passing 2000000
233     for doubling the respective time.
234 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
235     to a lexer start condition stack underrun.
236     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
237     USE_CODE_IF_NOT() preprocessor statements.
238 schoenebeck 2871
239 schoenebeck 3050 * Instruments DB:
240     - Fixed memory access bug of general DB access code which lead to
241     undefined behavior.
242 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
243     - The instrument DB path of linuxsampler's --create-instruments-db argument
244     is now optional, if it is missing, then a default location is used.
245 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
246     - Added support for scanning Sound Font (.sf2) files.
247 schoenebeck 3101 - Fixed undefined DB transaction behavior.

288 persson 2382
289 persson 2086 * general changes:
290 iliev 2012 - Refactoring: moved the independent code from
291     the Gigasampler format engine to base classes
292 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
293     respective profiling code is currently broken
294 schoenebeck 2053 - Introduced support for optional environment variable
295     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
296     where the sampler shall look for instrument editor plugins
297     (patch by Luis Garrido, slightly modified).
298 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
299     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
300     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
301     note (in this implementation of the sampler its simply hard routed to
302     the 1st effect send of the sampler channel, no matter what the actual
303     effect type is)
304     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
305     note (in this implementation of the sampler its simply hard routed to
306     the 2nd effect send of the sampler channel, no matter what the actual
307     effect type is)
308 schoenebeck 2124 - implemented support for internal LADSPA effects
309 schoenebeck 2140 - raised limit of program change queue from 100 to 512
310     (as suggested by Alex Stone)
311 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
312 iliev 2296 - experimental support for per voice equalization
313 iliev 2306 - added command line option --exec-after-init
314 schoenebeck 2330 - Introduced new C++ API method:
315     EngineChannel::InstrumentFileName(int index)
316     allowing to retrieve the whole list of files used for the loaded
317     instrument on an engine channel (a.k.a. part). Some GigaStudio
318     instruments for example are splitted over several files like
319     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
320 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
321     - Added new C++ API method Sampler::GetGlobalMaxStreams().
322     - Added new C++ API method Sampler::SetGlobalMaxVoices().
323     - Added new C++ API method Sampler::SetGlobalMaxStreams().
324 schoenebeck 2377 - Various "const" and "restrict" optimizations.
325 persson 2382 - all engines: add pan CC value to instrument pan parameter before
326     applying panning, instead of using two separate pan functions in
327     series (#182)
328 persson 2427 - added a lock guard class for exception safe mutex handling and
329     used it everywhere appropriate
330 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
331     - Exposed scale tuning to C++ API (along to the already existing standard
332     SysEx way).
333 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
334     and broken for ppc64. (Seq_cst loads and stores are actually not
335     used in LS, so the bug wasn't noticable.)
336     - lsatomic.h: added ARMv7 support
337 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
338     added various new C++ methods for this new feature / design change, old
339     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
340     as deprecated but are still there and should provide full behavior
341     backward compatibility).
342     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
343     unsafe and caused compilation error with clang 2.x).
344 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
345 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
346     sampler from the command line by providing LSCP aware features.
347 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
348     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
349     - VirtualMidiDevice: Added support for pitch bend.
350 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
351     polyphonic key pressure events (so far polyphonic pressure was not
352     supported at all, and channel pressure was rerouted as CC128 but not
353     used so far).
354 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
355     code is shared by all sampler engine implemementations, however only the
356     gig file format currently provides support for storing instrument scripts
357     (as LinuxSampler extension to the original GigaStudio 4 format).
358 iliev 2012
359 persson 2043 * Gigasampler format engine:
360     - implemented the "round robin keyboard" dimension
361     - fixed round robin and random dimensions for cases when number of
362     dimension zones is not a power of two
363     - made round robin use a counter for each region instead of each
364     key
365 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken

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

755     after MIDI/audio device creation failure
756 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the

758     took the full preloading time and on 1st program change the respective
759     instrument was completely reloaded again.
760 persson 2277 - fixed handling of rapid bank select and program change messages
761     sent to the same sampler channel (patch from the Open Octave

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

841     stacktrace mechanism seems to be broken on most systems at the moment)
842 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
843     a pointer to the launched InstrumentEditor object
844 schoenebeck 1876 - added optional 3rd party user data parameter for following

866 persson 1748 jack_client_new
867 iliev 1829 - added (experimental) CoreAudio driver
868 persson 1888 - applied old fixes to the ASIO driver that were included in the
869     previous binary release but accidentally never committed to CVS
870     (fixes #117)
871 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
872     win64)

886     exception when getting parameters from a disconnected device
887 schoenebeck 1599
888 persson 1651 * MIDI driver:
889     - added JACK MIDI driver
890 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
891     want to (mis)use it for some purpose ("fixed" in all current MIDI
892     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
893 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,

908     instrument database compilable
909 schoenebeck 1930 - added instrument database support on Windows
910     works with both standalone mode and VST plugin.
911     the instruments DB file is located in
912     %USERPROFILE%\.linuxsampler\instruments.db which allows different
913     databases for each windows user
914     if no DB is present it automatically creates the .linuxsampler subdir
915     and then creates an empty DB
916 persson 1943 - fixed recursive import, which was broken on Windows
917 iliev 1603
918 persson 1644 * Gigasampler format engine:
919     - fixed a memory leak that could happen when a channel was deleted

921 persson 1646 - made it possible to load an instrument even if the audio thread
922     isn't running
923 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
924     enough for piano gigs with pedal noise samples
925 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
926     respective FX send MIDI controller was used
927 schoenebeck 1724 - added support for GM global device volume SysEx message
928 schoenebeck 1762 (can be selected at compile time to either apply globally to the
929     whole sampler [default] or only to the sampler channels that are
930     connected to the respective MIDI input port the SysEx message arrived
931     on)
932 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
933     sometimes wrongly killed in the same buffer, causing no sound to
934     be played
935 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
936     which is usally used to switch a part between chromatic sounds and
937     drumkit sounds (as opposed to their common default setting of MIDI
938     part 10 being a drumkit part and all other ones chromatic parts), in
939     LS however one can switch between the first 16 MIDI instrument maps
940     defined for the sampler
941 persson 1764 - made it possible to create multiple sample channels even if the
942     audio thread isn't running
943 persson 1844 - fixed crash when removing channel with active voices (#116)
944 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
945     un-cache the respective sample if it's really not used by any
946     sampler engine anymore
947     - re-cache samples in case they were changed by an instrument editor,
948     e.g. when a sample was added while playing (#82)
949 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
950     same time stamp as the voice's note-on event and occured both in the
951     same audio fragment cycle (fixes bug #112)
952 persson 1858 - added support for the "fine tune" and "pitch bend range"
953     instrument-level gig parameters
954     - fixed minor artifacts in pitch bend handling
955 schoenebeck 1860 - added support for GS Reset SysEx message
956 persson 1862 - allow gig files to use unlimited downward pitch shifting
957     - added a limit check for upward pitch shifting
958 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
959     note was silent
960 persson 1923 - fixed crash happening when a pitch bend event arrived at the
961     same time a new instrument was loading
962 persson 1644
963 schoenebeck 1687 * LSCP server:
964     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
965     react on MIDI data arriving on certain sampler channels (so far only
966     Note-On and Note-Off events are sent via this LSCP event)
967 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
968     react on MIDI data arriving on certain MIDI input devices (so far only
969     Note-On and Note-Off events are sent via this LSCP event)
970 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
971     SET DB_INSTRUMENT FILE_PATH

973     frontends to send MIDI messages to specific sampler channel
974     - added two additional fields to GET FILE INSTRUMENT INFO command -
975     KEY_BINDINGS and KEYSWITCH_BINDINGS
976 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
977     was incorrect
978 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
979 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
980     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
981     be triggered respectively
982     - added new LSCP command "SET STREAMS" to globally alter the maximum
983     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
984     which will be triggered respectively
985 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
986     a gigedit file dialog is opened)
987 iliev 1848 - close all connections when LSCPServer is deleted
988 iliev 1882 - hard close of all sockets on exit

1007 iliev 1847 - fixed crash when changing the audio output device of a sampler
1008     channel with loaded instrument and start playing notes
1009 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1010 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit

1012 persson 1889 - fixed a memory management error which could cause a crash when a
1013     plugin was unloaded
1014 persson 1896 - bugfix: two private structs had the same name, which could cause

1029     - bugfix: the thread used by an editor plugin didn't die when the
1030     editor closed
1031 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1032     out all the space. operator--() did not apply size_mask after
1033     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1034     order to avoid problems with the _NonVolatileReader functions.
1035     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1036     GetWriteSpace(). Since this function is currently only used in
1037     the stream's qsort() compare function, it didn't trigger any
1038     bugs.
1039     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1040     24bit mode too. Faster method to read 24bit words on little

1053 senoner 1485 * MIDI driver:
1054 schoenebeck 1495 - added MME Windows MIDI driver
1055 senoner 1485
1056 schoenebeck 1471 * LSCP server:
1057     - added support for Windows style path / filenames, however with
1058     forward slash path separators instead of backslash
1059     (i.e. "C:/foo/bar.gig")
1060 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1061     apostrophes as well
1062 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1063     "LIST FILE INSTRUMENTS <file>" and
1064     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1065     about an arbitrary instrument file on the system where the sampler is
1066     running on
1067 schoenebeck 1471
1068 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1069 schoenebeck 947
1070 schoenebeck 1065 * packaging changes:
1071 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1072     API header files anymore
1073 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1074     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1075 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1076     capable to execute our autoconf environment, thus no need anymore
1077     to maintain the compile time configuration file (osx/version.h) for
1078     OSX manually (patch by Toshi Nagata)
1079 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1080     parameters
1081 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1082     C++ API header files, all implementation internal global definitions
1083     are now in global_private.h
1084     - atomic.h is not exposed to the C++ API anymore
1085     - no need to include config.h anymore for using LS's API header files
1086     - fixed warnings in API doc generation
1087 schoenebeck 1065
1088 schoenebeck 947 * general changes:
1089     - replaced the old, confusing MIDI program change mechanism by a
1090     flexible MIDI instrument mapper which allows to map arbitrary
1091 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1092 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1093     loaded on the respective channel when such MIDI program change
1094     messages arrive, beside that, each entry allows to define a life-time
1095     strategy for the instrument, so the user can define whether the
1096     instrument should i.e. be permanently loaded (to be able to switch
1097     quickly among sounds) or i.e. loaded just on demand when the
1098     respective program change arrives (to safe RAM space), as well as a
1099     global volume factor for each entry, so the user can adjust the volume
1100     dynamic of his mapped instrument collection without having to modify
1101 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1102     MIDI instrument maps and assign each sampler channel individually
1103     a certain map, so that i.e. separation of normal instruments and
1104     drumkits is possible
1105 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1106     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1107 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1108     due to a constant size RingBuffer FIFO which is now replaced by a
1109     dynamic (unlimited) size std::list FIFO
1110 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1111     output channels for being processed by external effect processors
1112     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1113     controllers
1114 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1115 iliev 1130 - Implemented new, improved notification system
1116 schoenebeck 1149 - fixed compilation errors regarding OSX
1117     (patch by Toshi Nagata)
1118 iliev 1161 - implemented instruments database
1119 iliev 1345 - added support for escape sequences to the instruments database
1120 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1121     within the sampler's process (by using instrument editor plugins),
1122     you'll notice the new "Registered instrument editors:" message on
1123 schoenebeck 1407 startup, added a new LSCP command:
1124     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1125 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1126     given sampler channel, the plugin path can be overridden at compile
1127     time with ./configure --enable-plugin-dir=/some/dir
1128 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1129     in the sampler's process to safely edit instruments while playing
1130     without a crash (hopefully) by either suspending single regions
1131     wherever possible or if unavoidable whole engine(s)
1132 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1133     policy and priority on thread level, set a minimum stack size for
1134     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1135     threads simply inherited properties of starting thread instead of
1136     setting their own policy and priority
1137 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1138     main process did not wait for the stack trace process to finish
1139     its output
1140 persson 1248 - fixed some minor memory leaks
1141 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1142     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1143 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1144     register, to avoid relocations in the text segment at runtime)
1145 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1146 schoenebeck 947
1147     * MIDI driver:
1148     - dispatch bank select (MSB and LSB) messages
1149    
1150 schoenebeck 1049 * audio driver:
1151     - the ALSA audio output driver parameters now reflect the correct
1152     parameter value ranges for the respective selected sound card
1153     (patch by Till Wimmer, a bit fixed and extended)
1154    
1155 persson 951 * Gigasampler format engine:
1156     - if a filter is used and EG2 finishes before EG1, let the voice
1157     die when EG2 has finished (this fixes a problem with clicks and
1158     voice starvation for some gigs)
1159 persson 1038 - playback is no longer disabled during instrument loading
1160     - all notes playing on a channel that changes its instrument keep
1161     playing with the old instrument until they get a note off
1162     command
1163 persson 1039 - EG fix: a release value of zero could cause noises or crash
1164 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1165 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1166     above max sustain level, which means that there is a decay phase
1167     even if sustain is 100%
1168 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1169     noises or crashes
1170 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1171 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1172     supplied to the configure script (fixes #46)
1173 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1174     instead of a fix value
1175 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1176     127 (solo mode) only kill voices if the respective mode really
1177     changed
1178 persson 951
1179 schoenebeck 1244 * LSCP server:
1180     - fixed compile time error for old Bison versions
1181     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1182 schoenebeck 1245 - parser now supports extended ASCII character set
1183     (up to ASCII code 255, i.e. includes now umlauts and accents)
1184     - filename arguments in LSCP commands now allow to use escape
1185     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1186     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1187     code value like \xf2) (fixes bug #24)
1188 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1189     least one of their text-based parameters (i.e. name, description):
1190     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1191     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1192     "SET DB_INSTRUMENT_DIRECTORY NAME",
1193     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1194     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1195     "FIND DB_INSTRUMENT_DIRECTORIES"
1196 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1197     occured, the unexpected character and the actually expected, possible
1198     character(s), the latter only if less than 5 possibilities)
1199 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1200     settings
1201 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1202     of strings were treated as being one string containing commas
1203     (fixes #57)
1204 schoenebeck 1244
1205 iliev 959 * Bug fixes:
1206     - fixed crash occurring on certain LSCP scripts (Bug 39)
1207 persson 1038 - another thread safety fix for lscp "load engine" and "set
1208     channel audio output device"
1209 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1210     on a sampler channel with connected MIDI device
1211 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1212     device connected to a sampler channel to number less then or equal
1213     to the index of the port to which the sampler channel is connected.
1214 iliev 1296 - The previous bindings were not been disconnected when altering
1215     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1216     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1217 iliev 1297 - The active stream/voice count statistic was incorrect.
1218 iliev 1298 - notification events were not been sent for some sampler
1219     channel changes
1220 iliev 1305 - added default min and max values to restrict the number of allowed
1221     audio output channels and MIDI input ports
1222 iliev 1306 - the connection to the PCM interface is now closed when destroying
1223     an audio output device
1224 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1225 iliev 959
1226 schoenebeck 1221 * test cases:
1227     - updated and fixed (haven't been touched in a while)
1228    
1229 schoenebeck 937 Version 0.4.0 (24 November 2006)
1230 persson 696
1231 schoenebeck 697 * packaging changes:
1232 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1233     to post-(un)install steps; added devel package for liblinuxsampler;
1234     to linuxsampler.spec (RPM)
1235 schoenebeck 697 - install necessary development header files for allowing 3rd party
1236     applications to link against liblinuxsampler
1237     - liblinuxsampler's API documentation can be generated with 'make docs'
1238     (Doxygen required)
1239 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1240     implementation (currently either an integer math solution or a
1241     di-harmonic approximation), automatic detection can be overriden
1242     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1243     configure script argument though (mandatory for cross-compilation)
1244 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1245     provided some on his own (as CXXFLAGS)
1246 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1247     messages
1248 schoenebeck 852 - added compile time options to allow disabling the various audio and
1249     MIDI drivers
1250 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1251     (patch by Ebrahim Mayat)
1252 schoenebeck 697
1253 persson 696 * Gigasampler format engine:
1254 schoenebeck 738 - extensive synthesis optimization
1255     (reimplementation of EGs and LFO(s), removed synthesis parameter
1256     prerendering and the synthesis parameter matrix in general, splitting
1257     each audio fragment into subfragments now where each subfragment uses
1258 persson 830 constant pitch and filter coefficients. The volume coefficient is
1259     linearly interpolated inside a subfragment, unless
1260     --disable-interpolate-volume is set.)
1261 persson 696 - fine tuning of the EG modulation parameters
1262 persson 729 - improved filter cutoff calculation by adding support for the
1263     following gig parameters: Cutoff freq (used when no cutoff
1264     controller is defined), Control invert, Minimum cutoff, Velocity
1265 persson 791 curve and Velocity range. The keyboard tracking now scales
1266     cutoff frequency instead of resonance.
1267 persson 877 - added support for gig parameter Resonance.
1268 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1269 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1270     which can be overridden with --enable-global-attenuation
1271 persson 783 - EG fixes: made the length of "attack hold" stage more
1272     accurate. Release stage can now start before attack stage
1273 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1274     time now has a minimal value to prevent clicks.
1275 persson 799 - fixed pitch changes larger than one octave
1276 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1277     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1278     all modes can be altered via standard GM messages, that is CC5 for
1279     altering portamento time, CC65 for enabling / disabling portamento
1280     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1281 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1282     parameter) and crossfade
1283 persson 831 - added support for the "attenuation controller threshold" gig
1284     parameter
1285 persson 832 - added smoothing of volume changes caused by control change
1286     messages
1287 persson 865 - sample loop parameters are now taken from the DimensionRegion
1288     instead of the wave chunk
1289     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1290     not equal to a power of two
1291 persson 877 - reimplementation of the filter algorithm. The new filter is more
1292     accurate and supports all gig filter types, including bandreject
1293     and lowpass turbo.
1294 persson 903 - real support for 24 bit samples - samples are not truncated to
1295     16 bits anymore
1296     - support for aftertouch (channel pressure, not polyphonic
1297     aftertouch)
1298 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1299     amplifying from 0)
1300 persson 696
1301 schoenebeck 711 * LSCP server:
1302     - fixed application exit on broken pipe error (fixes bug #20)
1303 iliev 793 - fixed the notification messages delay due to lack of
1304     network activity (fixes bug #26)
1305 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1306     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1307 schoenebeck 711
1308 schoenebeck 838 * audio driver:
1309     - added aRts audio output driver (by no means RT safe)
1310    
1311 schoenebeck 775 * MIDI driver:
1312     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1313     messages several times instead of once
1314 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1315     for events (i.e. for offline rendering based MIDI drivers)
1316 persson 922 - added checks for bad MIDI data
1317 schoenebeck 775
1318 schoenebeck 900 * linuxsampler application:
1319     - show available sampler engine types on startup
1320    
1321 schoenebeck 705 * general changes:
1322     - support for muting sampler channels and solo mode of the same, two new
1323     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1324     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1325     introduced for this, the behavior is the same like on a mixer console
1326 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1327     --enable-process-muted-channels which can be used to enable the
1328     processing of muted channels.
1329 iliev 777 - support for sostenuto pedal
1330 iliev 779 - support for monitoring the total number of active voices
1331 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1332     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1333 persson 835 - fixed some memory management errors
1334 persson 841 - fixed some concurrency problems that could lead to crashes when
1335     LSCP commands were executed
1336 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1337     sampler channel (fixes bug #36)
1338 schoenebeck 705
1339 schoenebeck 692 Version 0.3.3 (15 July 2005)
1340 schoenebeck 686
1341     * packaging changes:
1342     - fixed compilation with gcc 4.0
1343    
1344 schoenebeck 687 * Gigasampler format engine:
1345     - LFO preprocessing was performed even though the respective LFO was
1346     disabled by the instrument patch (minor efficiency fix)
1347 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1348     for volume ramp downs in the same fragment (needed for current voice
1349     stealing implementation) then simply inform the user with a warning
1350     about possible click sounds and reduce the volume ramp down
1351     appropriately instead of cancelling the audio device connection
1352 schoenebeck 687
1353 schoenebeck 677 Version 0.3.2 (24 June 2005)
1354 schoenebeck 609
1355     * packaging changes:
1356     - updated autotools build files to compile on OS X
1357     (conditional compilation of CoreMIDI and MidiShare drivers)
1358 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1359     './configure --disable-asm' (definitely not recommended)
1360 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1361     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1362     (due to 'dist-bzip2' automake option)
1363 schoenebeck 649
1364     * Gigasampler format engine:
1365     - support for the gig parameters for "release velocity response" curves
1366     - fine tuning of the EGADSR envelope
1367     - volume of release triggered samples now depends on note-on velocity,
1368     note length and gig parameter "release trigger decay" instead of
1369     note-off velocity.
1370 schoenebeck 663 - revised voice stealing
1371     (fixes crash and endless loop caused by voice stealing)
1372 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1373 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1374     instead of when the respective voice is actually launched
1375     (fixes undefined behavior if stolen voices belonged to a key group -
1376     this case was followed by a "killed voice survived" error message)
1377 schoenebeck 669 - fixed minor issue with null/silence samples
1378     (those stole voices even though they don't need a voice at all which
1379     resulted in "voice stealing didn't work out" messages)
1380 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1381     instrument or audio output device change
1382 schoenebeck 654
1383 schoenebeck 620 * LSCP server:
1384 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1385 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1386 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1387 schoenebeck 609
1388 schoenebeck 668 * linuxsampler application:
1389     - added command line parameters --lscp-addr and --lscp-port to override
1390     default IP address and port of LSCP server
1391    
1392 schoenebeck 579 Version 0.3.1 (24 May 2005)
1393    
1394     * initial release
