13    
14 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
15 schoenebeck 3381
16     * Real-time instrument scripts:
17     - Fixed behavior of built-in NKSP functions change_sustain(),
18     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
19     and change_cutoff_release().
20    
21 schoenebeck 3444 * general changes:
22     - Only play release trigger samples on sustain pedal up if this behaviour
23     was explicitly requested by the instrument (otherwise only on note-off).
24 persson 3455 - Fixed compiler warnings.
25     - Fixed compilation error when cross-compiling to Mac.
26 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
27     (see bug #169).
28     - LSCP doc: Be more clear describing the two distinct approaches
29     of using external vs. internal effects (see bug #169).
30 schoenebeck 3514 - "optional" class: Fixed comparison operators.
31 schoenebeck 3444
32 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
33     - Format extension: If requested by instrument then don't play release
34     trigger sample on note-off events.
35

37     - Fixed memory leak when releasing samples
38     (fixes bug #307, patch by Jacek Roszkowski)

40     (fixes bug #308, patch by Jacek Roszkowski).
41 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
42     (fixes bug #310, patch by Jacek Roszkowski).
43 schoenebeck 3487
44 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
45 persson 2837
46 persson 2856 * SFZ format engine:
47     - added support for <global>, <master> and #define (patch by Alby M)
48 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
49     - Added support for sfz extension opcode 'script' which may be used to
50     load real-time instrument script file (NKSP script language).
51 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
52 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.

54 persson 2856
55 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
56 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
57     cutoff settings.
58 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
59     all if an up-pitch of more than 40 semi tones was requested (I don't
60     think there is any stock gig sound that requires this behavior to
61     resemble its original sound).
62 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
63     be aborted (as LinuxSampler extension to the original GigaStudio 4
64     format).
65 schoenebeck 3072
66 persson 2837 * general changes:
67     - fixed printf type errors (mostly in debug messages)
68 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
69 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
70     allowing to sort data efficiently in real-time safe manner.
71     - RTList class: added methods for moving/inserting elements to arbitrary
72     position within a list.
73     - RTList class: added method fromPtr() for creating an Iterator object from
74     a raw element pointer.
75     - Attempt to partly fix resetting engine channels vs. resetting engine, an
76     overall cleanup of the Reset*(), ConnectAudioDevice(),
77     DisconnectAudioDevice() API methods would still be desirable though,
78     because the current situation is still inconsistent and error prone.
79 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
80     being directly assigned to a keyboard key. This allows more fine graded
81     processing of voices, which is i.e. required for certain instrument
82     script features.
83 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
84     (CC #64) events.
85     - Fix: Release trigger voices can now also distinguish correctly between
86     note-off and sustain pedal up events.
87 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
88     (while slow rate of crossfade smoother is preserved) to allow quick
89     volume and pan changes by instrument scripts for instance.
90 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
91     properly and thus were ignored for certain uses.
92 schoenebeck 3018 - Added new C++ API method
93     VirtualMidiDevice::SendChannelPressureToSampler().
94 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
95     sub threads is 16-byte aligned
96 schoenebeck 3054 - fixed numerous compiler warnings
97 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
98 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
99     fixes potential undefined behavior.
100 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
101     have a valid sample mapped (fixes bug #252).
102     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
103 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
104     subsequent optional argument due to glibc's implementation oddity
105     which expects a "=" sign, but no space between them.
106 persson 2837
107 schoenebeck 2866 * packaging changes:
108     - removed unnecessary dependency to libuuid
109     (originated by libgig's usage of it)
110 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
111     auto detect whether it (sh/c)ould output its messages in color.
112 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
113     substitution variable.
114     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
115 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
116     linuxsampler with instruments DB support.
117 schoenebeck 2866
118 schoenebeck 2871 * Real-time instrument scripts:
119     - Implemented scheduler for delayed MIDI events and for suspended scripts.
120     - Built-in script function "wait()": implemented support for function's
121     "duration-us" argument, thus scripts using this function are now
122     correctly resumed after the requested amount of microseconds.
123     - Built-in script function "play_note()": implemented support for
124     function's "duration-us" argument, thus notes triggered with this
125     argument are now correctly released after the requested amount of
126     microseconds.
127     - Fix: script events were not cleared when engine channel was reset,
128     potentially causing undefined behavior.
129     - Fixed crash which happened when trying to reference an undeclared
130     variable.
131 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
132     special value -1 for "duration-us" argument, which will cause the
133     triggered note to be released once the original note was released.
134 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
135     - Added new API method ScriptVM::syntaxHighlighting() which provides
136     a convenient syntax highlighting backend for external instrument
137     script editor applications.
138 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
139     - Extended parser issues to provide not only first line and first
140     column, but also last line and last column of issue (thus marking
141     the precise span of the issue within the source code).
142 schoenebeck 2902 - Reload script automatically after being modified by an instrument
143     editor.
144 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
145     like "on note end on".

151     - Implemented built-in script function "event_status()".
152     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
153     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
154     "event_status()" function.
155     - NKSP language: Added support for bitwise operators ".or.", ".and."
156     and ".not.".
157     - NKSP language scanner: Fixed IDs matching to require at least one
158     character (i.e. when matching function names or variable names).
159     - NKSP language scanner: disabled unusued rules.
160 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
161     be distinguished engine internally from "real" MIDI note on/off
162     events in order to avoid misbehaviors like hanging notes.
163 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
164     - Implemented built-in script variable "$NKSP_REAL_TIMER".
165     - Implemented built-in script variable "$NKSP_PERF_TIMER".
166     - Implemented built-in script variable "$ENGINE_UPTIME".
167 schoenebeck 2945 - Implemented built-in script function "inc()".
168     - Implemented built-in script function "dec()".
169     - NKSP language fix: division expressions were evaluated too often.
170     - NKSP language fix: string concatenation operator was right
171     associative instead of left (to right).
172 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
173     (i.e. "if end if").
174 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
175     - Implemented built-in script variable "$NI_CALLBACK_ID".
176     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
177     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
178     - Added support for read-only built-in variables (respectively
179     handled by the script parser).
180     - Added built-in script constant "$NI_CB_TYPE_INIT".
181     - Added built-in script constant "$NI_CB_TYPE_NOTE".
182     - Added built-in script constant "$NI_CB_TYPE_RELEASE".

186     - Implemented built-in script function "change_decay()".
187     - Implemented built-in script function "change_release()".
188 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
189     synthesis parameter changes immediately in case the respective note
190     was triggered at the same time, instead of scheduling the parameter
191     change, especially because it would cause some parameter types's
192     changes either to be ramped (i.e. change_vol()) or other types even
193     to have not effect at all (i.e. change_attack()).
194 schoenebeck 2965 - Implemented built-in script function "sh_left()".
195     - Implemented built-in script function "sh_right()".
196 schoenebeck 2970 - Implemented built-in script function "min()".

198 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
199     was loaded.
200     - NKSP built-in wait() script function: abort script execution if
201     a negative or zero wait time was passed as argument (since this is
202     a common indication of a bug either of the script or even of the
203     engine, which could lead to RT instability or even worse).
204 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
205     threatening scripts.
206 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
207 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
208     initializer list to an array variable.
209 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
210 schoenebeck 3076 - Implemented built-in script function "in_range()".

213     - Implemented built-in script function "change_pitch_lfo_depth()".
214     - Implemented built-in script function "change_pitch_lfo_freq()".
215 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
216     - Implemented built-in script function "change_tune_time()".
217     - Implemented built-in script function "fade_in()".
218     - Implemented built-in script function "fade_out()".
219     - Fixed acceptance of wrong data type of parameters passed to built-in
220     script functions "change_vol()", "change_tune()", "change_pan()",
221     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
222     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
223     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
224 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
225     of its possible parameter selections.
226     - Added built-in script function "set_event_par()" and implemented some
227     of its possible parameter selections.
228 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
229 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
230 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
231     built-in function "ignore_controller()".
232 schoenebeck 3214 - Implemented built-in script function "change_velo()".
233     - Implemented built-in script function "change_note()".
234 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
235     intuitive behavior if used in combination with "change_vol_time()" or
236     "change_tune_time()" respectively: now tuning/volume changes are only
237     assigned (without delay) immediately to a new note if the respective
238     timing function has not been called before, otherwise the volume/tuning
239     changes are automatically faded (before, only the event's time stamp was
240     relevant).
241 schoenebeck 3221 - Implemented built-in script function "array_equal()".
242     - Implemented built-in script function "search()".
243     - Implemented built-in script function "sort()".
244     - NKSP Fix: Never suspend "init" event handlers.
245 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
246     available for gig format engine).
247 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
248     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
249     - Implemented built-in script function "change_vol_curve()".
250     - Implemented built-in script function "change_tune_curve()".
251 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
252     offset with argument 3, where special value -1 means to use the regular
253     sample offset as defined by the instrument file.
254 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
255     - Built-in variable $EVENT_NOTE is now a read-only variable.
256     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
257     - built-in "play_note()" function now accepts -2 for its fourth argument
258     (note duration) which means the life time of the note shall be sticked
259     to the requested note number of argument 1.
260     - Fix: built-in "play_note()" function now returns 0 as result value if
261     -1 was passed for its fourth argument (note duration) and the respective
262     parent note is already gone.
263 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".

271     another script handler by passing its callback ID.
272 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
273     "init" event handlers.
274 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
275     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
276     to retrieve all code blocks filtered out by the preprocessor.
277 schoenebeck 3293 - Added built-in script function "fork()".
278     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
279     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
280     - Fixed potential crash when accessing dynamic built-in array variables.
281 schoenebeck 3296 - Added built-in script function "callback_status()".
282     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
283     - Added built-in constant $CALLBACK_STATUS_QUEUE.
284     - Added built-in constant $CALLBACK_STATUS_RUNNING.
285 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
286     "change_decay()" and "change_release()" to i.e. allow passing 2000000
287     for doubling the respective time.
288 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
289     to a lexer start condition stack underrun.
290     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
291     USE_CODE_IF_NOT() preprocessor statements.
292 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
293     can be set to disable all subsequent built-in "message()" function calls
294     on preprocessor level.
295 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
296 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
297     to avoid the editor app to crash on ill-formed text input.
298 schoenebeck 3335 - Added built-in script function "change_pan_time()".
299     - Added built-in script function "change_pan_curve()".

357 persson 2086 * general changes:
358 iliev 2012 - Refactoring: moved the independent code from
359     the Gigasampler format engine to base classes
360 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
361     respective profiling code is currently broken
362 schoenebeck 2053 - Introduced support for optional environment variable
363     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
364     where the sampler shall look for instrument editor plugins

367     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
368     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per

371     effect type is)
372     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
373     note (in this implementation of the sampler its simply hard routed to
374     the 2nd effect send of the sampler channel, no matter what the actual
375     effect type is)
376 schoenebeck 2124 - implemented support for internal LADSPA effects
377 schoenebeck 2140 - raised limit of program change queue from 100 to 512
378     (as suggested by Alex Stone)

380 iliev 2296 - experimental support for per voice equalization
381 iliev 2306 - added command line option --exec-after-init
382 schoenebeck 2330 - Introduced new C++ API method:
383     EngineChannel::InstrumentFileName(int index)
384     allowing to retrieve the whole list of files used for the loaded
385     instrument on an engine channel (a.k.a. part). Some GigaStudio
386     instruments for example are splitted over several files like
387     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
388 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
389     - Added new C++ API method Sampler::GetGlobalMaxStreams().
390     - Added new C++ API method Sampler::SetGlobalMaxVoices().
391     - Added new C++ API method Sampler::SetGlobalMaxStreams().
392 schoenebeck 2377 - Various "const" and "restrict" optimizations.
393 persson 2382 - all engines: add pan CC value to instrument pan parameter before
394     applying panning, instead of using two separate pan functions in
395     series (#182)
396 persson 2427 - added a lock guard class for exception safe mutex handling and
397     used it everywhere appropriate
398 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
399     - Exposed scale tuning to C++ API (along to the already existing standard
400     SysEx way).
401 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
402     and broken for ppc64. (Seq_cst loads and stores are actually not
403     used in LS, so the bug wasn't noticable.)
404     - lsatomic.h: added ARMv7 support
405 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
406     added various new C++ methods for this new feature / design change, old
407     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
408     as deprecated but are still there and should provide full behavior
409     backward compatibility).
410     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
411     unsafe and caused compilation error with clang 2.x).
412 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
413 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
414     sampler from the command line by providing LSCP aware features.
415 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
416     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
417     - VirtualMidiDevice: Added support for pitch bend.
418 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
419     polyphonic key pressure events (so far polyphonic pressure was not
420     supported at all, and channel pressure was rerouted as CC128 but not
421     used so far).
422 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
423     code is shared by all sampler engine implemementations, however only the
424     gig file format currently provides support for storing instrument scripts
425     (as LinuxSampler extension to the original GigaStudio 4 format).

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

826     took the full preloading time and on 1st program change the respective
827     instrument was completely reloaded again.

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

911     a pointer to the launched InstrumentEditor object
912 schoenebeck 1876 - added optional 3rd party user data parameter for following

936 persson 1888 - applied old fixes to the ASIO driver that were included in the
937     previous binary release but accidentally never committed to CVS
938     (fixes #117)
939 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on

976     instrument database compilable
977 schoenebeck 1930 - added instrument database support on Windows
978     works with both standalone mode and VST plugin.
979     the instruments DB file is located in
980     %USERPROFILE%\.linuxsampler\instruments.db which allows different

985 iliev 1603
986 persson 1644 * Gigasampler format engine:

992     enough for piano gigs with pedal noise samples
993 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
994     respective FX send MIDI controller was used
995 schoenebeck 1724 - added support for GM global device volume SysEx message
996 schoenebeck 1762 (can be selected at compile time to either apply globally to the

999     on)
1000 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1001     sometimes wrongly killed in the same buffer, causing no sound to
1002     be played
1003 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1004     which is usally used to switch a part between chromatic sounds and
1005     drumkit sounds (as opposed to their common default setting of MIDI
1006     part 10 being a drumkit part and all other ones chromatic parts), in
1007     LS however one can switch between the first 16 MIDI instrument maps
1008     defined for the sampler

1016     e.g. when a sample was added while playing (#82)
1017 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1018     same time stamp as the voice's note-on event and occured both in the

1020 persson 1858 - added support for the "fine tune" and "pitch bend range"
1021     instrument-level gig parameters

1024 persson 1862 - allow gig files to use unlimited downward pitch shifting
1025     - added a limit check for upward pitch shifting
1026 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1027     note was silent
1028 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1029     same time a new instrument was loading
1030 persson 1644
1031 schoenebeck 1687 * LSCP server:
1032     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to

1041     frontends to send MIDI messages to specific sampler channel
1042     - added two additional fields to GET FILE INSTRUMENT INFO command -
1043     KEY_BINDINGS and KEYSWITCH_BINDINGS
1044 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1045     was incorrect
1046 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1047 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1048     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1049     be triggered respectively

1067 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
1068     - fixed memory leaks when issuing the following LSCP commands:
1069     GET AUDIO_OUTPUT_DRIVER INFO
1070     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1071     GET MIDI_INPUT_DRIVER INFO
1072     GET MIDI_INPUT_DRIVER_PARAMETER INFO
1073     - fixed possible compilation error when sqlite is not present
1074 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1075 iliev 1847 - fixed crash when changing the audio output device of a sampler
1076     channel with loaded instrument and start playing notes
1077 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1078 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1079     PowerPC, which probably could cause crashes on that platform
1080 persson 1889 - fixed a memory management error which could cause a crash when a
1081     plugin was unloaded
1082 persson 1896 - bugfix: two private structs had the same name, which could cause
1083     problems if the linker chose the wrong constructor
1084 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1085     Windows

1088 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1089 schoenebeck 1454
1090     * packaging changes:
1091     - added autoconf checks for pthread library
1092     - added autoconf check for pthread bug found on certain NPTL-enabled
1093     glibc versions (see Gentoo bug report #194076)
1094 senoner 1502 - added autoconf checks for MS Windows
1095 schoenebeck 1454
1096 persson 1455 * general changes:
1097     - bugfix: the thread used by an editor plugin didn't die when the
1098     editor closed
1099 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1100     out all the space. operator--() did not apply size_mask after
1101     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1102     order to avoid problems with the _NonVolatileReader functions.
1103     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1104     GetWriteSpace(). Since this function is currently only used in
1105     the stream's qsort() compare function, it didn't trigger any
1106     bugs.
1107     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1108     24bit mode too. Faster method to read 24bit words on little
1109     endian machines (x86): replaced 3 byte reads + shifts with a 1
1110     unaligned 32bit read and shift
1111     - experimental support for MS Windows (MIDI input via MME, AUDIO
1112     output via ASIO)
1113     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1114 iliev 1541 - support for monitoring the total number of active disk streams
1115     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1116     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1117 persson 1455
1118 senoner 1500 * AUDIO driver:
1119 persson 1534 - added Windows ASIO low latency audio driver
1120 senoner 1500
1121 senoner 1485 * MIDI driver:
1122 schoenebeck 1495 - added MME Windows MIDI driver
1123 senoner 1485
1124 schoenebeck 1471 * LSCP server:
1125     - added support for Windows style path / filenames, however with
1126     forward slash path separators instead of backslash
1127     (i.e. "C:/foo/bar.gig")
1128 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1129     apostrophes as well
1130 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1131     "LIST FILE INSTRUMENTS <file>" and
1132     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1133     about an arbitrary instrument file on the system where the sampler is
1134     running on
1135 schoenebeck 1471
1136 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1137 schoenebeck 947
1138 schoenebeck 1065 * packaging changes:
1139 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1140     API header files anymore
1141 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1142     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1143 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1144     capable to execute our autoconf environment, thus no need anymore
1145     to maintain the compile time configuration file (osx/version.h) for
1146     OSX manually (patch by Toshi Nagata)
1147 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1148     parameters
1149 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1150     C++ API header files, all implementation internal global definitions
1151     are now in global_private.h
1152     - atomic.h is not exposed to the C++ API anymore
1153     - no need to include config.h anymore for using LS's API header files
1154     - fixed warnings in API doc generation
1155 schoenebeck 1065
1156 schoenebeck 947 * general changes:
1157     - replaced the old, confusing MIDI program change mechanism by a
1158     flexible MIDI instrument mapper which allows to map arbitrary
1159 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1160 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1161     loaded on the respective channel when such MIDI program change
1162     messages arrive, beside that, each entry allows to define a life-time
1163     strategy for the instrument, so the user can define whether the
1164     instrument should i.e. be permanently loaded (to be able to switch
1165     quickly among sounds) or i.e. loaded just on demand when the
1166     respective program change arrives (to safe RAM space), as well as a
1167     global volume factor for each entry, so the user can adjust the volume
1168     dynamic of his mapped instrument collection without having to modify
1169 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1170     MIDI instrument maps and assign each sampler channel individually
1171     a certain map, so that i.e. separation of normal instruments and
1172     drumkits is possible
1173 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1174     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1175 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1176     due to a constant size RingBuffer FIFO which is now replaced by a
1177     dynamic (unlimited) size std::list FIFO
1178 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1179     output channels for being processed by external effect processors
1180     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1181     controllers
1182 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1183 iliev 1130 - Implemented new, improved notification system
1184 schoenebeck 1149 - fixed compilation errors regarding OSX
1185     (patch by Toshi Nagata)
1186 iliev 1161 - implemented instruments database
1187 iliev 1345 - added support for escape sequences to the instruments database
1188 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1189     within the sampler's process (by using instrument editor plugins),
1190     you'll notice the new "Registered instrument editors:" message on
1191 schoenebeck 1407 startup, added a new LSCP command:
1192     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1193 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1194     given sampler channel, the plugin path can be overridden at compile
1195     time with ./configure --enable-plugin-dir=/some/dir
1196 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1197     in the sampler's process to safely edit instruments while playing
1198     without a crash (hopefully) by either suspending single regions
1199     wherever possible or if unavoidable whole engine(s)
1200 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1201     policy and priority on thread level, set a minimum stack size for
1202     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1203     threads simply inherited properties of starting thread instead of
1204     setting their own policy and priority
1205 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1206     main process did not wait for the stack trace process to finish
1207     its output
1208 persson 1248 - fixed some minor memory leaks
1209 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1210     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1211 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1212     register, to avoid relocations in the text segment at runtime)
1213 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1214 schoenebeck 947
1215     * MIDI driver:
1216     - dispatch bank select (MSB and LSB) messages
1217    
1218 schoenebeck 1049 * audio driver:
1219     - the ALSA audio output driver parameters now reflect the correct
1220     parameter value ranges for the respective selected sound card
1221     (patch by Till Wimmer, a bit fixed and extended)
1222    
1223 persson 951 * Gigasampler format engine:
1224     - if a filter is used and EG2 finishes before EG1, let the voice
1225     die when EG2 has finished (this fixes a problem with clicks and
1226     voice starvation for some gigs)
1227 persson 1038 - playback is no longer disabled during instrument loading
1228     - all notes playing on a channel that changes its instrument keep
1229     playing with the old instrument until they get a note off
1230     command
1231 persson 1039 - EG fix: a release value of zero could cause noises or crash
1232 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1233 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1234     above max sustain level, which means that there is a decay phase
1235     even if sustain is 100%
1236 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1237     noises or crashes
1238 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1239 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1240     supplied to the configure script (fixes #46)
1241 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1242     instead of a fix value
1243 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1244     127 (solo mode) only kill voices if the respective mode really
1245     changed
1246 persson 951
1247 schoenebeck 1244 * LSCP server:
1248     - fixed compile time error for old Bison versions
1249     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1250 schoenebeck 1245 - parser now supports extended ASCII character set
1251     (up to ASCII code 255, i.e. includes now umlauts and accents)
1252     - filename arguments in LSCP commands now allow to use escape
1253     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1254     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1255     code value like \xf2) (fixes bug #24)
1256 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1257     least one of their text-based parameters (i.e. name, description):
1258     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1259     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1260     "SET DB_INSTRUMENT_DIRECTORY NAME",
1261     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1262     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1263     "FIND DB_INSTRUMENT_DIRECTORIES"
1264 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1265     occured, the unexpected character and the actually expected, possible
1266     character(s), the latter only if less than 5 possibilities)
1267 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1268     settings
1269 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1270     of strings were treated as being one string containing commas
1271     (fixes #57)
1272 schoenebeck 1244
1273 iliev 959 * Bug fixes:
1274     - fixed crash occurring on certain LSCP scripts (Bug 39)
1275 persson 1038 - another thread safety fix for lscp "load engine" and "set
1276     channel audio output device"
1277 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1278     on a sampler channel with connected MIDI device
1279 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1280     device connected to a sampler channel to number less then or equal
1281     to the index of the port to which the sampler channel is connected.
1282 iliev 1296 - The previous bindings were not been disconnected when altering
1283     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1284     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1285 iliev 1297 - The active stream/voice count statistic was incorrect.
1286 iliev 1298 - notification events were not been sent for some sampler
1287     channel changes
1288 iliev 1305 - added default min and max values to restrict the number of allowed
1289     audio output channels and MIDI input ports
1290 iliev 1306 - the connection to the PCM interface is now closed when destroying
1291     an audio output device
1292 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1293 iliev 959
1294 schoenebeck 1221 * test cases:
1295     - updated and fixed (haven't been touched in a while)
1296    
1297 schoenebeck 937 Version 0.4.0 (24 November 2006)
1298 persson 696
1299 schoenebeck 697 * packaging changes:
1300 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1301     to post-(un)install steps; added devel package for liblinuxsampler;
1302     to linuxsampler.spec (RPM)
1303 schoenebeck 697 - install necessary development header files for allowing 3rd party
1304     applications to link against liblinuxsampler
1305     - liblinuxsampler's API documentation can be generated with 'make docs'
1306     (Doxygen required)
1307 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1308     implementation (currently either an integer math solution or a
1309     di-harmonic approximation), automatic detection can be overriden
1310     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1311     configure script argument though (mandatory for cross-compilation)
1312 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1313     provided some on his own (as CXXFLAGS)
1314 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1315     messages
1316 schoenebeck 852 - added compile time options to allow disabling the various audio and
1317     MIDI drivers
1318 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1319     (patch by Ebrahim Mayat)
1320 schoenebeck 697
1321 persson 696 * Gigasampler format engine:
1322 schoenebeck 738 - extensive synthesis optimization
1323     (reimplementation of EGs and LFO(s), removed synthesis parameter
1324     prerendering and the synthesis parameter matrix in general, splitting
1325     each audio fragment into subfragments now where each subfragment uses
1326 persson 830 constant pitch and filter coefficients. The volume coefficient is
1327     linearly interpolated inside a subfragment, unless
1328     --disable-interpolate-volume is set.)
1329 persson 696 - fine tuning of the EG modulation parameters
1330 persson 729 - improved filter cutoff calculation by adding support for the
1331     following gig parameters: Cutoff freq (used when no cutoff
1332     controller is defined), Control invert, Minimum cutoff, Velocity
1333 persson 791 curve and Velocity range. The keyboard tracking now scales
1334     cutoff frequency instead of resonance.
1335 persson 877 - added support for gig parameter Resonance.
1336 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1337 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1338     which can be overridden with --enable-global-attenuation
1339 persson 783 - EG fixes: made the length of "attack hold" stage more
1340     accurate. Release stage can now start before attack stage
1341 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1342     time now has a minimal value to prevent clicks.
1343 persson 799 - fixed pitch changes larger than one octave
1344 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1345     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1346     all modes can be altered via standard GM messages, that is CC5 for
1347     altering portamento time, CC65 for enabling / disabling portamento
1348     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1349 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1350     parameter) and crossfade
1351 persson 831 - added support for the "attenuation controller threshold" gig
1352     parameter
1353 persson 832 - added smoothing of volume changes caused by control change
1354     messages
1355 persson 865 - sample loop parameters are now taken from the DimensionRegion
1356     instead of the wave chunk
1357     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1358     not equal to a power of two
1359 persson 877 - reimplementation of the filter algorithm. The new filter is more
1360     accurate and supports all gig filter types, including bandreject
1361     and lowpass turbo.
1362 persson 903 - real support for 24 bit samples - samples are not truncated to
1363     16 bits anymore
1364     - support for aftertouch (channel pressure, not polyphonic
1365     aftertouch)
1366 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1367     amplifying from 0)
1368 persson 696
1369 schoenebeck 711 * LSCP server:
1370     - fixed application exit on broken pipe error (fixes bug #20)
1371 iliev 793 - fixed the notification messages delay due to lack of
1372     network activity (fixes bug #26)
1373 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1374     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1375 schoenebeck 711
1376 schoenebeck 838 * audio driver:
1377     - added aRts audio output driver (by no means RT safe)
1378    
1379 schoenebeck 775 * MIDI driver:
1380     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1381     messages several times instead of once
1382 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1383     for events (i.e. for offline rendering based MIDI drivers)
1384 persson 922 - added checks for bad MIDI data
1385 schoenebeck 775
1386 schoenebeck 900 * linuxsampler application:
1387     - show available sampler engine types on startup
1388    
1389 schoenebeck 705 * general changes:
1390     - support for muting sampler channels and solo mode of the same, two new
1391     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1392     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1393     introduced for this, the behavior is the same like on a mixer console
1394 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1395     --enable-process-muted-channels which can be used to enable the
1396     processing of muted channels.
1397 iliev 777 - support for sostenuto pedal
1398 iliev 779 - support for monitoring the total number of active voices
1399 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1400     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1401 persson 835 - fixed some memory management errors
1402 persson 841 - fixed some concurrency problems that could lead to crashes when
1403     LSCP commands were executed
1404 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1405     sampler channel (fixes bug #36)
1406 schoenebeck 705
1407 schoenebeck 692 Version 0.3.3 (15 July 2005)
1408 schoenebeck 686
1409     * packaging changes:
1410     - fixed compilation with gcc 4.0
1411    
1412 schoenebeck 687 * Gigasampler format engine:
1413     - LFO preprocessing was performed even though the respective LFO was
1414     disabled by the instrument patch (minor efficiency fix)
1415 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1416     for volume ramp downs in the same fragment (needed for current voice
1417     stealing implementation) then simply inform the user with a warning
1418     about possible click sounds and reduce the volume ramp down
1419     appropriately instead of cancelling the audio device connection
1420 schoenebeck 687
1421 schoenebeck 677 Version 0.3.2 (24 June 2005)
1422 schoenebeck 609
1423     * packaging changes:
1424     - updated autotools build files to compile on OS X
1425     (conditional compilation of CoreMIDI and MidiShare drivers)
1426 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1427     './configure --disable-asm' (definitely not recommended)
1428 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1429     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1430     (due to 'dist-bzip2' automake option)
1431 schoenebeck 649
1432     * Gigasampler format engine:
1433     - support for the gig parameters for "release velocity response" curves
1434     - fine tuning of the EGADSR envelope
1435     - volume of release triggered samples now depends on note-on velocity,
1436     note length and gig parameter "release trigger decay" instead of
1437     note-off velocity.
1438 schoenebeck 663 - revised voice stealing
1439     (fixes crash and endless loop caused by voice stealing)
1440 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1441 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
