* FX Sends: Provide more useful error messages on routing problems
  (see bug #169).
* LSCP reference doc: Be more clear describing the two distinct
  approaches of using external vs. internal effects (see bug #169).
* Bumped version (2.1.0.svn8).

1 schoenebeck 3381 Version SVN trunk (?)
2    
3     * Real-time instrument scripts:
4     - Fixed behavior of built-in NKSP functions change_sustain(),
5     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
6     and change_cutoff_release().
7    
8 schoenebeck 3444 * general changes:
9     - Only play release trigger samples on sustain pedal up if this behaviour
10     was explicitly requested by the instrument (otherwise only on note-off).
11 persson 3455 - Fixed compiler warnings.
12     - Fixed compilation error when cross-compiling to Mac.
13 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
14     (see bug #169).
15     - LSCP doc: Be more clear describing the two distinct approaches
16     of using external vs. internal effects (see bug #169).
17 schoenebeck 3444
18 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
19     - Format extension: If requested by instrument then don't play release
20     trigger sample on note-off events.
21    
22 schoenebeck 3487 * SFZ format engine:
23     - Fixed memory leak when releasing samples
24     (fixes bug #307, patch by Jacek Roszkowski)
25 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
26     (fixes bug #308, patch by Jacek Roszkowski).
27 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
28     (fixes bug #310, patch by Jacek Roszkowski).
29 schoenebeck 3487
30 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
31 persson 2837
32 persson 2856 * SFZ format engine:
33     - added support for <global>, <master> and #define (patch by Alby M)
34 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
35     - Added support for sfz extension opcode 'script' which may be used to
36     load real-time instrument script file (NKSP script language).
37 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
38 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
39 persson 3291 - sfz parser: allow missing space between header and opcode
40 persson 2856
41 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
42 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
43     cutoff settings.
44 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
45     all if an up-pitch of more than 40 semi tones was requested (I don't
46     think there is any stock gig sound that requires this behavior to
47     resemble its original sound).
48 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
49     be aborted (as LinuxSampler extension to the original GigaStudio 4
50     format).
51 schoenebeck 3072
52 persson 2837 * general changes:
53     - fixed printf type errors (mostly in debug messages)
54 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
55 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
56     allowing to sort data efficiently in real-time safe manner.
57     - RTList class: added methods for moving/inserting elements to arbitrary
58     position within a list.
59     - RTList class: added method fromPtr() for creating an Iterator object from
60     a raw element pointer.
61     - Attempt to partly fix resetting engine channels vs. resetting engine, an
62     overall cleanup of the Reset*(), ConnectAudioDevice(),
63     DisconnectAudioDevice() API methods would still be desirable though,
64     because the current situation is still inconsistent and error prone.
65 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
66     being directly assigned to a keyboard key. This allows more fine graded
67     processing of voices, which is i.e. required for certain instrument
68     script features.
69 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
70     (CC #64) events.
71     - Fix: Release trigger voices can now also distinguish correctly between
72     note-off and sustain pedal up events.
73 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
74     (while slow rate of crossfade smoother is preserved) to allow quick
75     volume and pan changes by instrument scripts for instance.
76 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
77     properly and thus were ignored for certain uses.
78 schoenebeck 3018 - Added new C++ API method
79     VirtualMidiDevice::SendChannelPressureToSampler().
80 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
81     sub threads is 16-byte aligned
82 schoenebeck 3054 - fixed numerous compiler warnings
83 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
84 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
85     fixes potential undefined behavior.
86 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
87     have a valid sample mapped (fixes bug #252).
88     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
89 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
90     subsequent optional argument due to glibc's implementation oddity
91     which expects a "=" sign, but no space between them.
92 persson 2837
93 schoenebeck 2866 * packaging changes:
94     - removed unnecessary dependency to libuuid
95     (originated by libgig's usage of it)
96 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
97     auto detect whether it (sh/c)ould output its messages in color.
98 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
99     substitution variable.
100     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
101 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
102     linuxsampler with instruments DB support.
103 schoenebeck 2866
104 schoenebeck 2871 * Real-time instrument scripts:
105     - Implemented scheduler for delayed MIDI events and for suspended scripts.
106     - Built-in script function "wait()": implemented support for function's
107     "duration-us" argument, thus scripts using this function are now
108     correctly resumed after the requested amount of microseconds.
109     - Built-in script function "play_note()": implemented support for
110     function's "duration-us" argument, thus notes triggered with this
111     argument are now correctly released after the requested amount of
112     microseconds.
113     - Fix: script events were not cleared when engine channel was reset,
114     potentially causing undefined behavior.
115     - Fixed crash which happened when trying to reference an undeclared
116     variable.
117 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
118     special value -1 for "duration-us" argument, which will cause the
119     triggered note to be released once the original note was released.
120 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
121     - Added new API method ScriptVM::syntaxHighlighting() which provides
122     a convenient syntax highlighting backend for external instrument
123     script editor applications.
124 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
125     - Extended parser issues to provide not only first line and first
126     column, but also last line and last column of issue (thus marking
127     the precise span of the issue within the source code).
128 schoenebeck 2902 - Reload script automatically after being modified by an instrument
129     editor.
130 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies

138     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
139     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
140     "event_status()" function.
141     - NKSP language: Added support for bitwise operators ".or.", ".and."
142     and ".not.".
143     - NKSP language scanner: Fixed IDs matching to require at least one
144     character (i.e. when matching function names or variable names).
145     - NKSP language scanner: disabled unusued rules.
146 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
147     be distinguished engine internally from "real" MIDI note on/off
148     events in order to avoid misbehaviors like hanging notes.
149 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
150     - Implemented built-in script variable "$NKSP_REAL_TIMER".
151     - Implemented built-in script variable "$NKSP_PERF_TIMER".

155     - NKSP language fix: division expressions were evaluated too often.
156     - NKSP language fix: string concatenation operator was right
157     associative instead of left (to right).
158 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
159     (i.e. "if end if").
160 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
161     - Implemented built-in script variable "$NI_CALLBACK_ID".
162     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
163     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

167     - Added built-in script constant "$NI_CB_TYPE_NOTE".
168     - Added built-in script constant "$NI_CB_TYPE_RELEASE".

172     - Implemented built-in script function "change_decay()".
173     - Implemented built-in script function "change_release()".
174 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
175     synthesis parameter changes immediately in case the respective note
176     was triggered at the same time, instead of scheduling the parameter
177     change, especially because it would cause some parameter types's
178     changes either to be ramped (i.e. change_vol()) or other types even
179     to have not effect at all (i.e. change_attack()).
180 schoenebeck 2965 - Implemented built-in script function "sh_left()".
181     - Implemented built-in script function "sh_right()".
182 schoenebeck 2970 - Implemented built-in script function "min()".

184 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
185     was loaded.
186     - NKSP built-in wait() script function: abort script execution if
187     a negative or zero wait time was passed as argument (since this is
188     a common indication of a bug either of the script or even of the
189     engine, which could lead to RT instability or even worse).
190 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
191     threatening scripts.
192 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
193 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
194     initializer list to an array variable.
195 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
196 schoenebeck 3076 - Implemented built-in script function "in_range()".

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

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

343 persson 2086 * general changes:
344 iliev 2012 - Refactoring: moved the independent code from
345     the Gigasampler format engine to base classes
346 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
347     respective profiling code is currently broken
348 schoenebeck 2053 - Introduced support for optional environment variable
349     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
350     where the sampler shall look for instrument editor plugins

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

356     the 1st effect send of the sampler channel, no matter what the actual
357     effect type is)
358     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
359     note (in this implementation of the sampler its simply hard routed to
360     the 2nd effect send of the sampler channel, no matter what the actual

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

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

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

837     (fixes #208)
838 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
839     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
840     practically irrelevant, however it caused problems with the new LSCP
841     shell's auto completion feature).
842 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
843     after each other (fixes #231).

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

921 iliev 1829 - added (experimental) CoreAudio driver
922 persson 1888 - applied old fixes to the ASIO driver that were included in the
923     previous binary release but accidentally never committed to CVS
924     (fixes #117)
925 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on

962     instrument database compilable
963 schoenebeck 1930 - added instrument database support on Windows
964     works with both standalone mode and VST plugin.
965     the instruments DB file is located in
966     %USERPROFILE%\.linuxsampler\instruments.db which allows different

968     if no DB is present it automatically creates the .linuxsampler subdir
969     and then creates an empty DB
970 persson 1943 - fixed recursive import, which was broken on Windows
971 iliev 1603
972 persson 1644 * Gigasampler format engine:

976     isn't running
977 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
978     enough for piano gigs with pedal noise samples
979 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
980     respective FX send MIDI controller was used
981 schoenebeck 1724 - added support for GM global device volume SysEx message
982 schoenebeck 1762 (can be selected at compile time to either apply globally to the

984     connected to the respective MIDI input port the SysEx message arrived
985     on)
986 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
987     sometimes wrongly killed in the same buffer, causing no sound to
988     be played
989 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
990     which is usally used to switch a part between chromatic sounds and
991     drumkit sounds (as opposed to their common default setting of MIDI
992     part 10 being a drumkit part and all other ones chromatic parts), in
993     LS however one can switch between the first 16 MIDI instrument maps
994     defined for the sampler
995 persson 1764 - made it possible to create multiple sample channels even if the
996     audio thread isn't running

1000     sampler engine anymore
1001     - re-cache samples in case they were changed by an instrument editor,
1002     e.g. when a sample was added while playing (#82)
1003 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1004     same time stamp as the voice's note-on event and occured both in the
1005     same audio fragment cycle (fixes bug #112)
1006 persson 1858 - added support for the "fine tune" and "pitch bend range"
1007     instrument-level gig parameters

1009 schoenebeck 1860 - added support for GS Reset SysEx message
1010 persson 1862 - allow gig files to use unlimited downward pitch shifting
1011     - added a limit check for upward pitch shifting
1012 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1013     note was silent
1014 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1015     same time a new instrument was loading
1016 persson 1644
1017 schoenebeck 1687 * LSCP server:
1018     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1019     react on MIDI data arriving on certain sampler channels (so far only

1021 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1022     react on MIDI data arriving on certain MIDI input devices (so far only
1023     Note-On and Note-Off events are sent via this LSCP event)

1028     - added two additional fields to GET FILE INSTRUMENT INFO command -
1029     KEY_BINDINGS and KEYSWITCH_BINDINGS
1030 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1031     was incorrect
1032 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1033 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1034     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1035     be triggered respectively
1036     - added new LSCP command "SET STREAMS" to globally alter the maximum
1037     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1038     which will be triggered respectively

1062     channel with loaded instrument and start playing notes
1063 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1064 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1065     PowerPC, which probably could cause crashes on that platform
1066 persson 1889 - fixed a memory management error which could cause a crash when a
1067     plugin was unloaded
1068 persson 1896 - bugfix: two private structs had the same name, which could cause
1069     problems if the linker chose the wrong constructor
1070 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1071     Windows

1074 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1075 schoenebeck 1454
1076     * packaging changes:
1077     - added autoconf checks for pthread library
1078     - added autoconf check for pthread bug found on certain NPTL-enabled
1079     glibc versions (see Gentoo bug report #194076)
1080 senoner 1502 - added autoconf checks for MS Windows
1081 schoenebeck 1454
1082 persson 1455 * general changes:
1083     - bugfix: the thread used by an editor plugin didn't die when the
1084     editor closed
1085 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1086     out all the space. operator--() did not apply size_mask after
1087     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1088     order to avoid problems with the _NonVolatileReader functions.
1089     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1090     GetWriteSpace(). Since this function is currently only used in
1091     the stream's qsort() compare function, it didn't trigger any
1092     bugs.
1093     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1094     24bit mode too. Faster method to read 24bit words on little
1095     endian machines (x86): replaced 3 byte reads + shifts with a 1
1096     unaligned 32bit read and shift
1097     - experimental support for MS Windows (MIDI input via MME, AUDIO
1098     output via ASIO)
1099     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1100 iliev 1541 - support for monitoring the total number of active disk streams
1101     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1102     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1103 persson 1455
1104 senoner 1500 * AUDIO driver:
1105 persson 1534 - added Windows ASIO low latency audio driver
1106 senoner 1500
1107 senoner 1485 * MIDI driver:
1108 schoenebeck 1495 - added MME Windows MIDI driver
1109 senoner 1485
1110 schoenebeck 1471 * LSCP server:
1111     - added support for Windows style path / filenames, however with
1112     forward slash path separators instead of backslash
1113     (i.e. "C:/foo/bar.gig")
1114 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1115     apostrophes as well
1116 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1117     "LIST FILE INSTRUMENTS <file>" and
1118     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1119     about an arbitrary instrument file on the system where the sampler is
1120     running on
1121 schoenebeck 1471
1122 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1123 schoenebeck 947
1124 schoenebeck 1065 * packaging changes:
1125 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1126     API header files anymore
1127 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1128     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1129 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1130     capable to execute our autoconf environment, thus no need anymore
1131     to maintain the compile time configuration file (osx/version.h) for
1132     OSX manually (patch by Toshi Nagata)
1133 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1134     parameters
1135 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1136     C++ API header files, all implementation internal global definitions
1137     are now in global_private.h
1138     - atomic.h is not exposed to the C++ API anymore
1139     - no need to include config.h anymore for using LS's API header files
1140     - fixed warnings in API doc generation
1141 schoenebeck 1065
1142 schoenebeck 947 * general changes:
1143     - replaced the old, confusing MIDI program change mechanism by a
1144     flexible MIDI instrument mapper which allows to map arbitrary
1145 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1146 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1147     loaded on the respective channel when such MIDI program change
1148     messages arrive, beside that, each entry allows to define a life-time
1149     strategy for the instrument, so the user can define whether the
1150     instrument should i.e. be permanently loaded (to be able to switch
1151     quickly among sounds) or i.e. loaded just on demand when the
1152     respective program change arrives (to safe RAM space), as well as a
1153     global volume factor for each entry, so the user can adjust the volume
1154     dynamic of his mapped instrument collection without having to modify
1155 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1156     MIDI instrument maps and assign each sampler channel individually
1157     a certain map, so that i.e. separation of normal instruments and
1158     drumkits is possible
1159 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1160     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1161 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1162     due to a constant size RingBuffer FIFO which is now replaced by a
1163     dynamic (unlimited) size std::list FIFO
1164 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1165     output channels for being processed by external effect processors
1166     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1167     controllers
1168 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1169 iliev 1130 - Implemented new, improved notification system
1170 schoenebeck 1149 - fixed compilation errors regarding OSX
1171     (patch by Toshi Nagata)
1172 iliev 1161 - implemented instruments database
1173 iliev 1345 - added support for escape sequences to the instruments database
1174 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1175     within the sampler's process (by using instrument editor plugins),
1176     you'll notice the new "Registered instrument editors:" message on
1177 schoenebeck 1407 startup, added a new LSCP command:
1178     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1179 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1180     given sampler channel, the plugin path can be overridden at compile
1181     time with ./configure --enable-plugin-dir=/some/dir
1182 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1183     in the sampler's process to safely edit instruments while playing
1184     without a crash (hopefully) by either suspending single regions
1185     wherever possible or if unavoidable whole engine(s)
1186 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1187     policy and priority on thread level, set a minimum stack size for
1188     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1189     threads simply inherited properties of starting thread instead of
1190     setting their own policy and priority
1191 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1192     main process did not wait for the stack trace process to finish
1193     its output
1194 persson 1248 - fixed some minor memory leaks
1195 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1196     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1197 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1198     register, to avoid relocations in the text segment at runtime)
1199 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1200 schoenebeck 947
1201     * MIDI driver:
1202     - dispatch bank select (MSB and LSB) messages
1203    
1204 schoenebeck 1049 * audio driver:
1205     - the ALSA audio output driver parameters now reflect the correct
1206     parameter value ranges for the respective selected sound card
1207     (patch by Till Wimmer, a bit fixed and extended)
1208    
1209 persson 951 * Gigasampler format engine:
1210     - if a filter is used and EG2 finishes before EG1, let the voice
1211     die when EG2 has finished (this fixes a problem with clicks and
1212     voice starvation for some gigs)
1213 persson 1038 - playback is no longer disabled during instrument loading
1214     - all notes playing on a channel that changes its instrument keep
1215     playing with the old instrument until they get a note off
1216     command
1217 persson 1039 - EG fix: a release value of zero could cause noises or crash
1218 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1219 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1220     above max sustain level, which means that there is a decay phase
1221     even if sustain is 100%
1222 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1223     noises or crashes
1224 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1225 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1226     supplied to the configure script (fixes #46)
1227 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1228     instead of a fix value
1229 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1230     127 (solo mode) only kill voices if the respective mode really
1231     changed
1232 persson 951
1233 schoenebeck 1244 * LSCP server:
1234     - fixed compile time error for old Bison versions
1235     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1236 schoenebeck 1245 - parser now supports extended ASCII character set
1237     (up to ASCII code 255, i.e. includes now umlauts and accents)
1238     - filename arguments in LSCP commands now allow to use escape
1239     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1240     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1241     code value like \xf2) (fixes bug #24)
1242 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1243     least one of their text-based parameters (i.e. name, description):
1244     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1245     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1246     "SET DB_INSTRUMENT_DIRECTORY NAME",
1247     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1248     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1249     "FIND DB_INSTRUMENT_DIRECTORIES"
1250 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1251     occured, the unexpected character and the actually expected, possible
1252     character(s), the latter only if less than 5 possibilities)
1253 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1254     settings
1255 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1256     of strings were treated as being one string containing commas
1257     (fixes #57)
1258 schoenebeck 1244
1259 iliev 959 * Bug fixes:
1260     - fixed crash occurring on certain LSCP scripts (Bug 39)
1261 persson 1038 - another thread safety fix for lscp "load engine" and "set
1262     channel audio output device"
1263 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1264     on a sampler channel with connected MIDI device
1265 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1266     device connected to a sampler channel to number less then or equal
1267     to the index of the port to which the sampler channel is connected.
1268 iliev 1296 - The previous bindings were not been disconnected when altering
1269     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1270     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1271 iliev 1297 - The active stream/voice count statistic was incorrect.
1272 iliev 1298 - notification events were not been sent for some sampler
1273     channel changes
1274 iliev 1305 - added default min and max values to restrict the number of allowed
1275     audio output channels and MIDI input ports
1276 iliev 1306 - the connection to the PCM interface is now closed when destroying
1277     an audio output device
1278 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1279 iliev 959
1280 schoenebeck 1221 * test cases:
1281     - updated and fixed (haven't been touched in a while)
1282    
1283 schoenebeck 937 Version 0.4.0 (24 November 2006)
1284 persson 696
1285 schoenebeck 697 * packaging changes:
1286 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1287     to post-(un)install steps; added devel package for liblinuxsampler;
1288     to linuxsampler.spec (RPM)
1289 schoenebeck 697 - install necessary development header files for allowing 3rd party
1290     applications to link against liblinuxsampler
1291     - liblinuxsampler's API documentation can be generated with 'make docs'
1292     (Doxygen required)
1293 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1294     implementation (currently either an integer math solution or a
1295     di-harmonic approximation), automatic detection can be overriden
1296     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1297     configure script argument though (mandatory for cross-compilation)
1298 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1299     provided some on his own (as CXXFLAGS)
1300 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1301     messages
1302 schoenebeck 852 - added compile time options to allow disabling the various audio and
1303     MIDI drivers
1304 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1305     (patch by Ebrahim Mayat)
1306 schoenebeck 697
1307 persson 696 * Gigasampler format engine:
1308 schoenebeck 738 - extensive synthesis optimization
1309     (reimplementation of EGs and LFO(s), removed synthesis parameter
1310     prerendering and the synthesis parameter matrix in general, splitting
1311     each audio fragment into subfragments now where each subfragment uses
1312 persson 830 constant pitch and filter coefficients. The volume coefficient is
1313     linearly interpolated inside a subfragment, unless
1314     --disable-interpolate-volume is set.)
1315 persson 696 - fine tuning of the EG modulation parameters
1316 persson 729 - improved filter cutoff calculation by adding support for the
1317     following gig parameters: Cutoff freq (used when no cutoff
1318     controller is defined), Control invert, Minimum cutoff, Velocity
1319 persson 791 curve and Velocity range. The keyboard tracking now scales
1320     cutoff frequency instead of resonance.
1321 persson 877 - added support for gig parameter Resonance.
1322 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1323 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1324     which can be overridden with --enable-global-attenuation
1325 persson 783 - EG fixes: made the length of "attack hold" stage more
1326     accurate. Release stage can now start before attack stage
1327 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1328     time now has a minimal value to prevent clicks.
1329 persson 799 - fixed pitch changes larger than one octave
1330 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1331     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1332     all modes can be altered via standard GM messages, that is CC5 for
1333     altering portamento time, CC65 for enabling / disabling portamento
1334     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1335 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1336     parameter) and crossfade
1337 persson 831 - added support for the "attenuation controller threshold" gig
1338     parameter
1339 persson 832 - added smoothing of volume changes caused by control change
1340     messages
1341 persson 865 - sample loop parameters are now taken from the DimensionRegion
1342     instead of the wave chunk
1343     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1344     not equal to a power of two
1345 persson 877 - reimplementation of the filter algorithm. The new filter is more
1346     accurate and supports all gig filter types, including bandreject
1347     and lowpass turbo.
1348 persson 903 - real support for 24 bit samples - samples are not truncated to
1349     16 bits anymore
1350     - support for aftertouch (channel pressure, not polyphonic
1351     aftertouch)
1352 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1353     amplifying from 0)
1354 persson 696
1355 schoenebeck 711 * LSCP server:
1356     - fixed application exit on broken pipe error (fixes bug #20)
1357 iliev 793 - fixed the notification messages delay due to lack of
1358     network activity (fixes bug #26)
1359 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1360     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1361 schoenebeck 711
1362 schoenebeck 838 * audio driver:
1363     - added aRts audio output driver (by no means RT safe)
1364    
1365 schoenebeck 775 * MIDI driver:
1366     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1367     messages several times instead of once
1368 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1369     for events (i.e. for offline rendering based MIDI drivers)
1370 persson 922 - added checks for bad MIDI data
1371 schoenebeck 775
1372 schoenebeck 900 * linuxsampler application:
1373     - show available sampler engine types on startup
1374    
1375 schoenebeck 705 * general changes:
1376     - support for muting sampler channels and solo mode of the same, two new
1377     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1378     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1379     introduced for this, the behavior is the same like on a mixer console
1380 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1381     --enable-process-muted-channels which can be used to enable the
1382     processing of muted channels.
1383 iliev 777 - support for sostenuto pedal
1384 iliev 779 - support for monitoring the total number of active voices
1385 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1386     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1387 persson 835 - fixed some memory management errors
1388 persson 841 - fixed some concurrency problems that could lead to crashes when
1389     LSCP commands were executed
1390 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1391     sampler channel (fixes bug #36)
1392 schoenebeck 705
1393 schoenebeck 692 Version 0.3.3 (15 July 2005)
1394 schoenebeck 686
1395     * packaging changes:
1396     - fixed compilation with gcc 4.0
1397    
1398 schoenebeck 687 * Gigasampler format engine:
1399     - LFO preprocessing was performed even though the respective LFO was
1400     disabled by the instrument patch (minor efficiency fix)
1401 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1402     for volume ramp downs in the same fragment (needed for current voice
1403     stealing implementation) then simply inform the user with a warning
1404     about possible click sounds and reduce the volume ramp down
1405     appropriately instead of cancelling the audio device connection
1406 schoenebeck 687
1407 schoenebeck 677 Version 0.3.2 (24 June 2005)
1408 schoenebeck 609
1409     * packaging changes:
1410     - updated autotools build files to compile on OS X
1411     (conditional compilation of CoreMIDI and MidiShare drivers)
1412 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1413     './configure --disable-asm' (definitely not recommended)
1414 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1415     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1416     (due to 'dist-bzip2' automake option)
1417 schoenebeck 649
1418     * Gigasampler format engine:
1419     - support for the gig parameters for "release velocity response" curves
1420     - fine tuning of the EGADSR envelope
1421     - volume of release triggered samples now depends on note-on velocity,
1422     note length and gig parameter "release trigger decay" instead of
1423     note-off velocity.
1424 schoenebeck 663 - revised voice stealing
1425     (fixes crash and endless loop caused by voice stealing)
1426 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1427 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1428     instead of when the respective voice is actually launched
1429     (fixes undefined behavior if stolen voices belonged to a key group -
1430     this case was followed by a "killed voice survived" error message)
1431 schoenebeck 669 - fixed minor issue with null/silence samples
1432     (those stole voices even though they don't need a voice at all which
1433     resulted in "voice stealing didn't work out" messages)
1434 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1435     instrument or audio output device change
1436 schoenebeck 654
