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

132        - Implemented built-in script function "change_reso()".
133        - Implemented built-in script function "event_status()".
134        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
135          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
136          "event_status()" function.
137        - NKSP language: Added support for bitwise operators ".or.", ".and."
138          and ".not.".
139        - NKSP language scanner: Fixed IDs matching to require at least one
140          character (i.e. when matching function names or variable names).
141        - NKSP language scanner: disabled unusued rules.
142        - Fixed behavior of play_note() and note_off() functions which must
143          be distinguished engine internally from "real" MIDI note on/off
144          events in order to avoid misbehaviors like hanging notes.
145        - Implemented built-in script variable "$KSP_TIMER".
146        - Implemented built-in script variable "$NKSP_REAL_TIMER".
147        - Implemented built-in script variable "$NKSP_PERF_TIMER".
148        - Implemented built-in script variable "$ENGINE_UPTIME".
149        - Implemented built-in script function "inc()".
150        - Implemented built-in script function "dec()".
151        - NKSP language fix: division expressions were evaluated too often.
152        - NKSP language fix: string concatenation operator was right
153          associative instead of left (to right).
154        - NKSP language correction: allow empty statements in entire language
155          (i.e. "if end if").
156        - Implemented built-in script function "stop_wait()".
157        - Implemented built-in script variable "$NI_CALLBACK_ID".
158        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
159        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
160        - Added support for read-only built-in variables (respectively
161          handled by the script parser).
162        - Added built-in script constant "$NI_CB_TYPE_INIT".
163        - Added built-in script constant "$NI_CB_TYPE_NOTE".
164        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
165        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".

168        - Implemented built-in script function "change_decay()".
169        - Implemented built-in script function "change_release()".
170        - Fixed all change_*() built-in script functions to apply their
171          synthesis parameter changes immediately in case the respective note
172          was triggered at the same time, instead of scheduling the parameter
173          change, especially because it would cause some parameter types's
174          changes either to be ramped (i.e. change_vol()) or other types even
175          to have not effect at all (i.e. change_attack()).
176        - Implemented built-in script function "sh_left()".
177        - Implemented built-in script function "sh_right()".
178        - Implemented built-in script function "min()".
179        - Implemented built-in script function "max()".
180        - NKSP Fix: "init" event handler was not always executed when a script
181          was loaded.
182        - NKSP built-in wait() script function: abort script execution if
183          a negative or zero wait time was passed as argument (since this is
184          a common indication of a bug either of the script or even of the
185          engine, which could lead to RT instability or even worse).
186        - ScriptVM: Implemented automatic suspension of RT safety
187          threatening scripts.
188        - Provide more user friendly error messages on syntax errors.
189        - Fixed NKSP parser warning "Not a statement" when assigning an
190          initializer list to an array variable.
191        - Implemented built-in script array variable "%ALL_EVENTS".
192        - Implemented built-in script function "in_range()".
193        - Implemented built-in script function "change_amp_lfo_depth()".

195        - Implemented built-in script function "change_pitch_lfo_depth()".
196        - Implemented built-in script function "change_pitch_lfo_freq()".
197        - Implemented built-in script function "change_vol_time()".
198        - Implemented built-in script function "change_tune_time()".
199        - Implemented built-in script function "fade_in()".
200        - Implemented built-in script function "fade_out()".
201        - Fixed acceptance of wrong data type of parameters passed to built-in
202          script functions "change_vol()", "change_tune()", "change_pan()",
203          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
204          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
205          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
206        - Added built-in script function "get_event_par()" and implemented some
207          of its possible parameter selections.
208        - Added built-in script function "set_event_par()" and implemented some
209          of its possible parameter selections.
210        - Fixed a bunch of scheduler time related bugs.
211        - Fixed polyphonic variables not being reset to zero after usage.
212        - Built-in "ignore_event()" function: argument is now optional, like with
213          built-in function "ignore_controller()".
214        - Implemented built-in script function "change_velo()".
215        - Implemented built-in script function "change_note()".
216        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
217          intuitive behavior if used in combination with "change_vol_time()" or
218          "change_tune_time()" respectively: now tuning/volume changes are only
219          assigned (without delay) immediately to a new note if the respective
220          timing function has not been called before, otherwise the volume/tuning
221          changes are automatically faded (before, only the event's time stamp was
222          relevant).
223         - Implemented built-in script function "array_equal()".
224         - Implemented built-in script function "search()".
225         - Implemented built-in script function "sort()".
226         - NKSP Fix: Never suspend "init" event handlers.
227         - Implemented built-in script function "same_region()" (currently only
228           available for gig format engine).
229         - Added built-in script constant "$NKSP_LINEAR".
230         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
231         - Implemented built-in script function "change_vol_curve()".
232         - Implemented built-in script function "change_tune_curve()".
233         - built-in "play_note()" function now supports a sample playback start
234           offset with argument 3, where special value -1 means to use the regular
235           sample offset as defined by the instrument file.
236         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
237         - Built-in variable $EVENT_NOTE is now a read-only variable.
238         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
239         - built-in "play_note()" function now accepts -2 for its fourth argument
240           (note duration) which means the life time of the note shall be sticked
241           to the requested note number of argument 1.
242         - Fix: built-in "play_note()" function now returns 0 as result value if
243           -1 was passed for its fourth argument (note duration) and the respective
244           parent note is already gone.
245        - Implemented built-in script function "change_play_pos()".
246        - NKSP language: Added support for user declared const array variables.
247        - NKSP language: Raise parser warning if array variable is accessed with
248          an index that exceeds the array's size.
249        - NKSP language fix: Unknown characters were not handled correctly.
250        - NKSP language: Added support for "synchronized .. end synchronized"
251          code blocks.
252        - Implemented built-in script function "abort()" which allows to abort
253          another script handler by passing its callback ID.
254        - Fixed potential memory access bug and potential undefined behavior of
255          "init" event handlers.
256        - Print a time stamp along to each call of built-in function "message()".
257        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
258          to retrieve all code blocks filtered out by the preprocessor.
259        - Added built-in script function "fork()".
260        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
261        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
262        - Fixed potential crash when accessing dynamic built-in array variables.
263        - Added built-in script function "callback_status()".
264        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
265        - Added built-in constant $CALLBACK_STATUS_QUEUE.
266        - Added built-in constant $CALLBACK_STATUS_RUNNING.
267        - Removed max. value limitation of built-in functions "change_attack()",
268          "change_decay()" and "change_release()" to i.e. allow passing 2000000
269          for doubling the respective time.
270        - NKSP script editor syntax highlighting API: Fixed app termination due
271          to a lexer start condition stack underrun.
272        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
273          USE_CODE_IF_NOT() preprocessor statements.
274        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
275          can be set to disable all subsequent built-in "message()" function calls
276          on preprocessor level.
277        - Implemented built-in script function "change_sustain()".
278        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
279          to avoid the editor app to crash on ill-formed text input.
280        - Added built-in script function "change_pan_time()".
281        - Added built-in script function "change_pan_curve()".
282        - Added built-in script function "change_cutoff_attack()".
283        - Added built-in script function "change_cutoff_decay()".
284        - Added built-in script function "change_cutoff_sustain()".
285        - Added built-in script function "change_cutoff_release()".
286        - Added built-in script function "change_cutoff_lfo_depth()".
287        - Added built-in script function "change_cutoff_lfo_freq()".
288    
289      * Instruments DB:
290        - Fixed memory access bug of general DB access code which lead to
291          undefined behavior.
292        - Cleanup of instruments DB file creation and opening code.
293        - The instrument DB path of linuxsampler's --create-instruments-db argument
294          is now optional, if it is missing, then a default location is used.
295        - Added support for scanning SFZ (.sfz) files.
296        - Added support for scanning Sound Font (.sf2) files.
297        - Fixed undefined DB transaction behavior.
298    
299    Version 2.0.0 (15 July 2015)
300    
301      * packaging changes:
302        - fixed building with newer MinGW-w64
303        - Mac OS X: support the new dir for Core Audio SDK
304        - Mac OS X: fixed building outside source directory
305        - made sure all source files for hostplugins are included when
306          doing "make dist"
307        - removed empty directories left from the cvs to svn migration
308        - fixed compilation with gcc 4.6.1
309        - another "make dist" fix, for the LV2 plugin
310        - made --enable-pthread-testcancel default on Mac OS X
311        - minor Makefile fix for building lscpparser when build and source
312          directories are separate
313        - Mac OS X: made it possible to specify plugin installation dir to

332        - fixed build error on newer MinGW
333        - support building with older jack versions
334        - support building with spaces in vst sdk path
335        - enabled automake 'subdir-objects' option and moved external
336          source references (vst, au, asio) from makefiles to cpp files,
337          in order to get rid of warnings from automake 1.14
338    
339      * general changes:
340        - Refactoring: moved the independent code from
341          the Gigasampler format engine to base classes
342        - command line option '--profile' is currently disabled, since the
343          respective profiling code is currently broken
344        - Introduced support for optional environment variable
345          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
346          where the sampler shall look for instrument editor plugins
347          (patch by Luis Garrido, slightly modified).
348        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
349        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
350        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
351          note (in this implementation of the sampler its simply hard routed to
352          the 1st effect send of the sampler channel, no matter what the actual
353          effect type is)
354        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
355          note (in this implementation of the sampler its simply hard routed to
356          the 2nd effect send of the sampler channel, no matter what the actual
357          effect type is)
358        - implemented support for internal LADSPA effects
359        - raised limit of program change queue from 100 to 512
360          (as suggested by Alex Stone)
361        - implemented sine LFO, pulse LFO and saw LFO
362        - experimental support for per voice equalization
363        - added command line option --exec-after-init
364        - Introduced new C++ API method:
365          EngineChannel::InstrumentFileName(int index)
366          allowing to retrieve the whole list of files used for the loaded
367          instrument on an engine channel (a.k.a. part). Some GigaStudio
368          instruments for example are splitted over several files like
369          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
370        - Added new C++ API method Sampler::GetGlobalMaxVoices().
371        - Added new C++ API method Sampler::GetGlobalMaxStreams().
372        - Added new C++ API method Sampler::SetGlobalMaxVoices().
373        - Added new C++ API method Sampler::SetGlobalMaxStreams().
374        - Various "const" and "restrict" optimizations.
375        - all engines: add pan CC value to instrument pan parameter before
376          applying panning, instead of using two separate pan functions in
377          series (#182)
378        - added a lock guard class for exception safe mutex handling and
379          used it everywhere appropriate
380        - Immediately apply scale tuning changes to active voices.
381        - Exposed scale tuning to C++ API (along to the already existing standard
382          SysEx way).
383        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
384          and broken for ppc64. (Seq_cst loads and stores are actually not
385          used in LS, so the bug wasn't noticable.)
386        - lsatomic.h: added ARMv7 support
387        - Added support for multiple MIDI input ports per sampler channel (and
388          added various new C++ methods for this new feature / design change, old
389          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
390          as deprecated but are still there and should provide full behavior
391          backward compatibility).
392        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
393          unsafe and caused compilation error with clang 2.x).
394        - Bugfix: only process the latest MIDI program change event.
395        - Introducing the LSCP shell, which provides convenient control of the
396          sampler from the command line by providing LSCP aware features.
397        - VirtualMidiDevice: Added support for program change.
398        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
399        - VirtualMidiDevice: Added support for pitch bend.
400        - Aftertouch: extended API to explicitly handle channel pressure and
401          polyphonic key pressure events (so far polyphonic pressure was not
402          supported at all, and channel pressure was rerouted as CC128 but not
403          used so far).
404        - Added initial support for real-time instrument scripts. The script VM
405          code is shared by all sampler engine implemementations, however only the
406          gig file format currently provides support for storing instrument scripts
407          (as LinuxSampler extension to the original GigaStudio 4 format).

420          min value
421        - Exclusive Groups: don't ever stop voices of the same note,

605        - Listen to all interfaces on Mac OS X (INADDR_ANY)
606        - VST bugfix: If the host called resume() before and after
607          changing sample rate or block size, the number of channels was
608          incorrectly set to two. This caused silence in Cubase 5.
609        - save engine type (gig, sfz or sf2) in plugin state
610        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
611          64 bit Windows
612        - AU: changed number of output channels from one stereo to 16
613          stereo

627        - VST: fixed crashes on Linux Ardour and EnergyXT
628        - DSSI bugfix: it wasn't possible to change engine type. The MIDI

650          there is no reason for this limit
651        - MME: fixed memory handling bug found with cppcheck
652        - MME: removed compiler warning
653        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
654          which allows to retrieve the list of CoreMIDI clients / ports and to connect
655          to them a la JACK, via the usual sampler APIs
656        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
657          the driver will automatically connect to other CoreMIDI clients' ports

666        - MME bugfix: driver wasn't closed properly
667        - CoreMIDI: automatically connect to all input sources by default (driver
668          parameter "AUTO_BIND").
669        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
670        - CoreMIDI: fixed minor memory leak
671    
672      * audio driver:
673        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
674        - JACK audio: react on sample rate changes.

677          RT context.
678        - ASIO driver: removed compiler warnings
679        - CoreAudio: fixed minor error handling bug
680        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

806        - When creating MIDI instrument map entries with "PERSISTENT" type, the
807          instruments were uselessly precached with zero samples, however it still
808          took the full preloading time and on 1st program change the respective
809          instrument was completely reloaded again.
810        - fixed handling of rapid bank select and program change messages
811          sent to the same sampler channel (patch from the Open Octave

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