* SFZ: Fixed memory leak when releasing samples
  (fixes bug #307, patch by Jacek Roszkowski)
* Bumped version (2.1.0.svn5).

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

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

147     - NKSP language fix: division expressions were evaluated too often.
148     - NKSP language fix: string concatenation operator was right
149     associative instead of left (to right).
150 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
151     (i.e. "if end if").
152 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
153     - Implemented built-in script variable "$NI_CALLBACK_ID".
154     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
155     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
156     - Added support for read-only built-in variables (respectively

159     - Added built-in script constant "$NI_CB_TYPE_NOTE".
160     - Added built-in script constant "$NI_CB_TYPE_RELEASE".

164     - Implemented built-in script function "change_decay()".
165     - Implemented built-in script function "change_release()".
166 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
167     synthesis parameter changes immediately in case the respective note
168     was triggered at the same time, instead of scheduling the parameter
169     change, especially because it would cause some parameter types's
170     changes either to be ramped (i.e. change_vol()) or other types even
171     to have not effect at all (i.e. change_attack()).
172 schoenebeck 2965 - Implemented built-in script function "sh_left()".

176 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
177     was loaded.
178     - NKSP built-in wait() script function: abort script execution if
179     a negative or zero wait time was passed as argument (since this is
180     a common indication of a bug either of the script or even of the
181     engine, which could lead to RT instability or even worse).
182 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
183     threatening scripts.
184 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
185 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an

192     - Implemented built-in script function "change_pitch_lfo_freq()".
193 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
194     - Implemented built-in script function "change_tune_time()".
195     - Implemented built-in script function "fade_in()".
196     - Implemented built-in script function "fade_out()".
197     - Fixed acceptance of wrong data type of parameters passed to built-in
198     script functions "change_vol()", "change_tune()", "change_pan()",
199     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
200     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
201     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
202 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
203     of its possible parameter selections.
204     - Added built-in script function "set_event_par()" and implemented some
205     of its possible parameter selections.
206 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
207 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
208 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
209     built-in function "ignore_controller()".
210 schoenebeck 3214 - Implemented built-in script function "change_velo()".
211     - Implemented built-in script function "change_note()".
212 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
213     intuitive behavior if used in combination with "change_vol_time()" or
214     "change_tune_time()" respectively: now tuning/volume changes are only
215     assigned (without delay) immediately to a new note if the respective
216     timing function has not been called before, otherwise the volume/tuning
217     changes are automatically faded (before, only the event's time stamp was
218     relevant).
219 schoenebeck 3221 - Implemented built-in script function "array_equal()".
220     - Implemented built-in script function "search()".
221     - Implemented built-in script function "sort()".

223 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
224     available for gig format engine).
225 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
226     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
227     - Implemented built-in script function "change_vol_curve()".
228     - Implemented built-in script function "change_tune_curve()".
229 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
230     offset with argument 3, where special value -1 means to use the regular
231     sample offset as defined by the instrument file.
232 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
233     - Built-in variable $EVENT_NOTE is now a read-only variable.
234     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
235     - built-in "play_note()" function now accepts -2 for its fourth argument
236     (note duration) which means the life time of the note shall be sticked
237     to the requested note number of argument 1.
238     - Fix: built-in "play_note()" function now returns 0 as result value if
239     -1 was passed for its fourth argument (note duration) and the respective
240     parent note is already gone.
241 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".

249     another script handler by passing its callback ID.
250 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
251     "init" event handlers.
252 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
253     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
254     to retrieve all code blocks filtered out by the preprocessor.
255 schoenebeck 3293 - Added built-in script function "fork()".
256     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
257     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
258     - Fixed potential crash when accessing dynamic built-in array variables.
259 schoenebeck 3296 - Added built-in script function "callback_status()".
260     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
261     - Added built-in constant $CALLBACK_STATUS_QUEUE.
262     - Added built-in constant $CALLBACK_STATUS_RUNNING.
263 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",

265     for doubling the respective time.
266 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
267     to a lexer start condition stack underrun.
268     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
269     USE_CODE_IF_NOT() preprocessor statements.
270 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
271     can be set to disable all subsequent built-in "message()" function calls
272     on preprocessor level.
273 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
274 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
275     to avoid the editor app to crash on ill-formed text input.
276 schoenebeck 3335 - Added built-in script function "change_pan_time()".
277     - Added built-in script function "change_pan_curve()".

334 persson 2382
335 persson 2086 * general changes:
336 iliev 2012 - Refactoring: moved the independent code from
337     the Gigasampler format engine to base classes
338 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
339     respective profiling code is currently broken
340 schoenebeck 2053 - Introduced support for optional environment variable
341     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
342     where the sampler shall look for instrument editor plugins
343     (patch by Luis Garrido, slightly modified).
344 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
345     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
346     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
347     note (in this implementation of the sampler its simply hard routed to
348     the 1st effect send of the sampler channel, no matter what the actual
349     effect type is)
350     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
351     note (in this implementation of the sampler its simply hard routed to
352     the 2nd effect send of the sampler channel, no matter what the actual
353     effect type is)
354 schoenebeck 2124 - implemented support for internal LADSPA effects
355 schoenebeck 2140 - raised limit of program change queue from 100 to 512

361     EngineChannel::InstrumentFileName(int index)
362     allowing to retrieve the whole list of files used for the loaded
363     instrument on an engine channel (a.k.a. part). Some GigaStudio
364     instruments for example are splitted over several files like
365     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
366 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().

370 schoenebeck 2377 - Various "const" and "restrict" optimizations.
371 persson 2382 - all engines: add pan CC value to instrument pan parameter before
372     applying panning, instead of using two separate pan functions in
373     series (#182)
374 persson 2427 - added a lock guard class for exception safe mutex handling and
375     used it everywhere appropriate
376 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
377     - Exposed scale tuning to C++ API (along to the already existing standard
378     SysEx way).
379 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
380     and broken for ppc64. (Seq_cst loads and stores are actually not
381     used in LS, so the bug wasn't noticable.)
382     - lsatomic.h: added ARMv7 support
383 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
384     added various new C++ methods for this new feature / design change, old
385     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
386     as deprecated but are still there and should provide full behavior
387     backward compatibility).
388     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
389     unsafe and caused compilation error with clang 2.x).
390 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
391 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
392     sampler from the command line by providing LSCP aware features.

394     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
395     - VirtualMidiDevice: Added support for pitch bend.
396 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
397     polyphonic key pressure events (so far polyphonic pressure was not
398     supported at all, and channel pressure was rerouted as CC128 but not
399     used so far).
400 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
401     code is shared by all sampler engine implemementations, however only the
402     gig file format currently provides support for storing instrument scripts
403     (as LinuxSampler extension to the original GigaStudio 4 format).

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

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

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

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

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

954     instrument database compilable
955 schoenebeck 1930 - added instrument database support on Windows
956     works with both standalone mode and VST plugin.
957     the instruments DB file is located in
958     %USERPROFILE%\.linuxsampler\instruments.db which allows different

960     if no DB is present it automatically creates the .linuxsampler subdir
961     and then creates an empty DB
962 persson 1943 - fixed recursive import, which was broken on Windows
963 iliev 1603
964 persson 1644 * Gigasampler format engine:

969 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
970     enough for piano gigs with pedal noise samples
971 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
972     respective FX send MIDI controller was used
973 schoenebeck 1724 - added support for GM global device volume SysEx message
974 schoenebeck 1762 (can be selected at compile time to either apply globally to the

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

992     sampler engine anymore
993     - re-cache samples in case they were changed by an instrument editor,
994     e.g. when a sample was added while playing (#82)
995 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
996     same time stamp as the voice's note-on event and occured both in the
997     same audio fragment cycle (fixes bug #112)
998 persson 1858 - added support for the "fine tune" and "pitch bend range"
999     instrument-level gig parameters
1000     - fixed minor artifacts in pitch bend handling
1001 schoenebeck 1860 - added support for GS Reset SysEx message
1002 persson 1862 - allow gig files to use unlimited downward pitch shifting
1003     - added a limit check for upward pitch shifting
1004 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1005     note was silent
1006 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1007     same time a new instrument was loading
1008 persson 1644
1009 schoenebeck 1687 * LSCP server:
1010     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1011     react on MIDI data arriving on certain sampler channels (so far only
1012     Note-On and Note-Off events are sent via this LSCP event)
1013 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1014     react on MIDI data arriving on certain MIDI input devices (so far only
1015     Note-On and Note-Off events are sent via this LSCP event)

1020     - added two additional fields to GET FILE INSTRUMENT INFO command -
1021     KEY_BINDINGS and KEYSWITCH_BINDINGS
1022 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1023     was incorrect
1024 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1025 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1026     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1027     be triggered respectively
1028     - added new LSCP command "SET STREAMS" to globally alter the maximum
1029     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1030     which will be triggered respectively

1064 iliev 1761
1065    
1066 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1067 schoenebeck 1454
1068     * packaging changes:
1069     - added autoconf checks for pthread library
1070     - added autoconf check for pthread bug found on certain NPTL-enabled
1071     glibc versions (see Gentoo bug report #194076)
1072 senoner 1502 - added autoconf checks for MS Windows
1073 schoenebeck 1454
1074 persson 1455 * general changes:
1075     - bugfix: the thread used by an editor plugin didn't die when the
1076     editor closed
1077 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1078     out all the space. operator--() did not apply size_mask after
1079     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1080     order to avoid problems with the _NonVolatileReader functions.
1081     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1082     GetWriteSpace(). Since this function is currently only used in
1083     the stream's qsort() compare function, it didn't trigger any
1084     bugs.
1085     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1086     24bit mode too. Faster method to read 24bit words on little
1087     endian machines (x86): replaced 3 byte reads + shifts with a 1
1088     unaligned 32bit read and shift
1089     - experimental support for MS Windows (MIDI input via MME, AUDIO
1090     output via ASIO)
1091     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1092 iliev 1541 - support for monitoring the total number of active disk streams
1093     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1094     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1095 persson 1455
1096 senoner 1500 * AUDIO driver:
1097 persson 1534 - added Windows ASIO low latency audio driver
1098 senoner 1500
1099 senoner 1485 * MIDI driver:
1100 schoenebeck 1495 - added MME Windows MIDI driver
1101 senoner 1485
1102 schoenebeck 1471 * LSCP server:
1103     - added support for Windows style path / filenames, however with
1104     forward slash path separators instead of backslash
1105     (i.e. "C:/foo/bar.gig")
1106 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1107     apostrophes as well
1108 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1109     "LIST FILE INSTRUMENTS <file>" and
1110     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1111     about an arbitrary instrument file on the system where the sampler is
1112     running on
1113 schoenebeck 1471
1114 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1115 schoenebeck 947
1116 schoenebeck 1065 * packaging changes:
1117 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1118     API header files anymore
1119 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1120     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1121 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1122     capable to execute our autoconf environment, thus no need anymore
1123     to maintain the compile time configuration file (osx/version.h) for
1124     OSX manually (patch by Toshi Nagata)
1125 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1126     parameters
1127 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1128     C++ API header files, all implementation internal global definitions
1129     are now in global_private.h
1130     - atomic.h is not exposed to the C++ API anymore
1131     - no need to include config.h anymore for using LS's API header files
1132     - fixed warnings in API doc generation
1133 schoenebeck 1065
1134 schoenebeck 947 * general changes:
1135     - replaced the old, confusing MIDI program change mechanism by a
1136     flexible MIDI instrument mapper which allows to map arbitrary
1137 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1138 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1139     loaded on the respective channel when such MIDI program change
1140     messages arrive, beside that, each entry allows to define a life-time
1141     strategy for the instrument, so the user can define whether the
1142     instrument should i.e. be permanently loaded (to be able to switch
1143     quickly among sounds) or i.e. loaded just on demand when the
1144     respective program change arrives (to safe RAM space), as well as a
1145     global volume factor for each entry, so the user can adjust the volume
1146     dynamic of his mapped instrument collection without having to modify
1147 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1148     MIDI instrument maps and assign each sampler channel individually
1149     a certain map, so that i.e. separation of normal instruments and
1150     drumkits is possible
1151 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1152     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1153 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1154     due to a constant size RingBuffer FIFO which is now replaced by a
1155     dynamic (unlimited) size std::list FIFO
1156 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1157     output channels for being processed by external effect processors
1158     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1159     controllers
1160 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1161 iliev 1130 - Implemented new, improved notification system
1162 schoenebeck 1149 - fixed compilation errors regarding OSX
1163     (patch by Toshi Nagata)
1164 iliev 1161 - implemented instruments database
1165 iliev 1345 - added support for escape sequences to the instruments database
1166 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1167     within the sampler's process (by using instrument editor plugins),
1168     you'll notice the new "Registered instrument editors:" message on
1169 schoenebeck 1407 startup, added a new LSCP command:
1170     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1171 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1172     given sampler channel, the plugin path can be overridden at compile
1173     time with ./configure --enable-plugin-dir=/some/dir
1174 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1175     in the sampler's process to safely edit instruments while playing
1176     without a crash (hopefully) by either suspending single regions
1177     wherever possible or if unavoidable whole engine(s)
1178 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1179     policy and priority on thread level, set a minimum stack size for
1180     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1181     threads simply inherited properties of starting thread instead of
1182     setting their own policy and priority
1183 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1184     main process did not wait for the stack trace process to finish
1185     its output
1186 persson 1248 - fixed some minor memory leaks
1187 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1188     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1189 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1190     register, to avoid relocations in the text segment at runtime)
1191 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1192 schoenebeck 947
1193     * MIDI driver:
1194     - dispatch bank select (MSB and LSB) messages
1195    
1196 schoenebeck 1049 * audio driver:
1197     - the ALSA audio output driver parameters now reflect the correct
1198     parameter value ranges for the respective selected sound card
1199     (patch by Till Wimmer, a bit fixed and extended)
1200    
1201 persson 951 * Gigasampler format engine:
1202     - if a filter is used and EG2 finishes before EG1, let the voice
1203     die when EG2 has finished (this fixes a problem with clicks and
1204     voice starvation for some gigs)
1205 persson 1038 - playback is no longer disabled during instrument loading
1206     - all notes playing on a channel that changes its instrument keep
1207     playing with the old instrument until they get a note off
1208     command
1209 persson 1039 - EG fix: a release value of zero could cause noises or crash
1210 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1211 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1212     above max sustain level, which means that there is a decay phase
1213     even if sustain is 100%
1214 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1215     noises or crashes
1216 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1217 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1218     supplied to the configure script (fixes #46)
1219 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1220     instead of a fix value
1221 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1222     127 (solo mode) only kill voices if the respective mode really
1223     changed
1224 persson 951
1225 schoenebeck 1244 * LSCP server:
1226     - fixed compile time error for old Bison versions
1227     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1228 schoenebeck 1245 - parser now supports extended ASCII character set
1229     (up to ASCII code 255, i.e. includes now umlauts and accents)
1230     - filename arguments in LSCP commands now allow to use escape
1231     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1232     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1233     code value like \xf2) (fixes bug #24)
1234 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1235     least one of their text-based parameters (i.e. name, description):
1236     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1237     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1238     "SET DB_INSTRUMENT_DIRECTORY NAME",
1239     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1240     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1241     "FIND DB_INSTRUMENT_DIRECTORIES"
1242 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1243     occured, the unexpected character and the actually expected, possible
1244     character(s), the latter only if less than 5 possibilities)
1245 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1246     settings
1247 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1248     of strings were treated as being one string containing commas
1249     (fixes #57)
1250 schoenebeck 1244
1251 iliev 959 * Bug fixes:
1252     - fixed crash occurring on certain LSCP scripts (Bug 39)
1253 persson 1038 - another thread safety fix for lscp "load engine" and "set
1254     channel audio output device"
1255 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1256     on a sampler channel with connected MIDI device
1257 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1258     device connected to a sampler channel to number less then or equal
1259     to the index of the port to which the sampler channel is connected.
1260 iliev 1296 - The previous bindings were not been disconnected when altering
1261     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1262     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1263 iliev 1297 - The active stream/voice count statistic was incorrect.
1264 iliev 1298 - notification events were not been sent for some sampler
1265     channel changes
1266 iliev 1305 - added default min and max values to restrict the number of allowed
1267     audio output channels and MIDI input ports
1268 iliev 1306 - the connection to the PCM interface is now closed when destroying
1269     an audio output device
1270 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1271 iliev 959
1272 schoenebeck 1221 * test cases:
1273     - updated and fixed (haven't been touched in a while)
1274    
1275 schoenebeck 937 Version 0.4.0 (24 November 2006)
1276 persson 696
1277 schoenebeck 697 * packaging changes:
1278 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1279     to post-(un)install steps; added devel package for liblinuxsampler;
1280     to linuxsampler.spec (RPM)
1281 schoenebeck 697 - install necessary development header files for allowing 3rd party
1282     applications to link against liblinuxsampler
1283     - liblinuxsampler's API documentation can be generated with 'make docs'
1284     (Doxygen required)
1285 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1286     implementation (currently either an integer math solution or a
1287     di-harmonic approximation), automatic detection can be overriden
1288     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1289     configure script argument though (mandatory for cross-compilation)
1290 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1291     provided some on his own (as CXXFLAGS)
1292 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1293     messages
1294 schoenebeck 852 - added compile time options to allow disabling the various audio and
1295     MIDI drivers
1296 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1297     (patch by Ebrahim Mayat)
1298 schoenebeck 697
1299 persson 696 * Gigasampler format engine:
1300 schoenebeck 738 - extensive synthesis optimization
1301     (reimplementation of EGs and LFO(s), removed synthesis parameter
1302     prerendering and the synthesis parameter matrix in general, splitting
1303     each audio fragment into subfragments now where each subfragment uses
1304 persson 830 constant pitch and filter coefficients. The volume coefficient is
1305     linearly interpolated inside a subfragment, unless
1306     --disable-interpolate-volume is set.)
1307 persson 696 - fine tuning of the EG modulation parameters
1308 persson 729 - improved filter cutoff calculation by adding support for the
1309     following gig parameters: Cutoff freq (used when no cutoff
1310     controller is defined), Control invert, Minimum cutoff, Velocity
1311 persson 791 curve and Velocity range. The keyboard tracking now scales
1312     cutoff frequency instead of resonance.
1313 persson 877 - added support for gig parameter Resonance.
1314 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1315 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1316     which can be overridden with --enable-global-attenuation
1317 persson 783 - EG fixes: made the length of "attack hold" stage more
1318     accurate. Release stage can now start before attack stage
1319 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1320     time now has a minimal value to prevent clicks.
1321 persson 799 - fixed pitch changes larger than one octave
1322 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1323     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1324     all modes can be altered via standard GM messages, that is CC5 for
1325     altering portamento time, CC65 for enabling / disabling portamento
1326     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1327 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1328     parameter) and crossfade
1329 persson 831 - added support for the "attenuation controller threshold" gig
1330     parameter
1331 persson 832 - added smoothing of volume changes caused by control change
1332     messages
1333 persson 865 - sample loop parameters are now taken from the DimensionRegion
1334     instead of the wave chunk
1335     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1336     not equal to a power of two
1337 persson 877 - reimplementation of the filter algorithm. The new filter is more
1338     accurate and supports all gig filter types, including bandreject
1339     and lowpass turbo.
1340 persson 903 - real support for 24 bit samples - samples are not truncated to
1341     16 bits anymore
1342     - support for aftertouch (channel pressure, not polyphonic
1343     aftertouch)
1344 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1345     amplifying from 0)
1346 persson 696
1347 schoenebeck 711 * LSCP server:
1348     - fixed application exit on broken pipe error (fixes bug #20)
1349 iliev 793 - fixed the notification messages delay due to lack of
1350     network activity (fixes bug #26)
1351 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1352     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1353 schoenebeck 711
1354 schoenebeck 838 * audio driver:
1355     - added aRts audio output driver (by no means RT safe)
1356    
1357 schoenebeck 775 * MIDI driver:
1358     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1359     messages several times instead of once
1360 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1361     for events (i.e. for offline rendering based MIDI drivers)
1362 persson 922 - added checks for bad MIDI data
1363 schoenebeck 775
1364 schoenebeck 900 * linuxsampler application:
1365     - show available sampler engine types on startup
1366    
1367 schoenebeck 705 * general changes:
1368     - support for muting sampler channels and solo mode of the same, two new
1369     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1370     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1371     introduced for this, the behavior is the same like on a mixer console
1372 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1373     --enable-process-muted-channels which can be used to enable the
1374     processing of muted channels.
1375 iliev 777 - support for sostenuto pedal
1376 iliev 779 - support for monitoring the total number of active voices
1377 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1378     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1379 persson 835 - fixed some memory management errors
1380 persson 841 - fixed some concurrency problems that could lead to crashes when
1381     LSCP commands were executed
1382 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1383     sampler channel (fixes bug #36)
1384 schoenebeck 705
1385 schoenebeck 692 Version 0.3.3 (15 July 2005)
1386 schoenebeck 686
1387     * packaging changes:
1388     - fixed compilation with gcc 4.0
1389    
1390 schoenebeck 687 * Gigasampler format engine:
1391     - LFO preprocessing was performed even though the respective LFO was
1392     disabled by the instrument patch (minor efficiency fix)
1393 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1394     for volume ramp downs in the same fragment (needed for current voice
1395     stealing implementation) then simply inform the user with a warning
1396     about possible click sounds and reduce the volume ramp down
1397     appropriately instead of cancelling the audio device connection
1398 schoenebeck 687
1399 schoenebeck 677 Version 0.3.2 (24 June 2005)
1400 schoenebeck 609
1401     * packaging changes:
1402     - updated autotools build files to compile on OS X
1403     (conditional compilation of CoreMIDI and MidiShare drivers)
1404 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1405     './configure --disable-asm' (definitely not recommended)
1406 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1407     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1408     (due to 'dist-bzip2' automake option)
1409 schoenebeck 649
1410     * Gigasampler format engine:
1411     - support for the gig parameters for "release velocity response" curves
1412     - fine tuning of the EGADSR envelope
1413     - volume of release triggered samples now depends on note-on velocity,
1414     note length and gig parameter "release trigger decay" instead of
1415     note-off velocity.
1416 schoenebeck 663 - revised voice stealing
1417     (fixes crash and endless loop caused by voice stealing)
1418 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1419 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1420     instead of when the respective voice is actually launched
1421     (fixes undefined behavior if stolen voices belonged to a key group -
1422     this case was followed by a "killed voice survived" error message)
1423 schoenebeck 669 - fixed minor issue with null/silence samples
1424     (those stole voices even though they don't need a voice at all which
1425     resulted in "voice stealing didn't work out" messages)
1426 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1427     instrument or audio output device change
1428 schoenebeck 654
1429 schoenebeck 620 * LSCP server:
1430 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1431 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1432 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1433 schoenebeck 609
1434 schoenebeck 668 * linuxsampler application:
1435     - added command line parameters --lscp-addr and --lscp-port to override
1436     default IP address and port of LSCP server
1437    
1438 schoenebeck 579 Version 0.3.1 (24 May 2005)
1439    
1440     * initial release
