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

166        - Implemented built-in script function "change_decay()".
167        - Implemented built-in script function "change_release()".
168        - Fixed all change_*() built-in script functions to apply their
169          synthesis parameter changes immediately in case the respective note
170          was triggered at the same time, instead of scheduling the parameter
171          change, especially because it would cause some parameter types's
172          changes either to be ramped (i.e. change_vol()) or other types even
173          to have not effect at all (i.e. change_attack()).
174        - Implemented built-in script function "sh_left()".
175        - Implemented built-in script function "sh_right()".
176        - Implemented built-in script function "min()".
177        - Implemented built-in script function "max()".
178        - NKSP Fix: "init" event handler was not always executed when a script
179          was loaded.
180        - NKSP built-in wait() script function: abort script execution if
181          a negative or zero wait time was passed as argument (since this is
182          a common indication of a bug either of the script or even of the
183          engine, which could lead to RT instability or even worse).
184        - ScriptVM: Implemented automatic suspension of RT safety
185          threatening scripts.
186        - Provide more user friendly error messages on syntax errors.
187        - Fixed NKSP parser warning "Not a statement" when assigning an
188          initializer list to an array variable.
189        - Implemented built-in script array variable "%ALL_EVENTS".
190        - Implemented built-in script function "in_range()".
191        - Implemented built-in script function "change_amp_lfo_depth()".
192        - Implemented built-in script function "change_amp_lfo_freq()".
193        - Implemented built-in script function "change_pitch_lfo_depth()".
194        - Implemented built-in script function "change_pitch_lfo_freq()".
195        - Implemented built-in script function "change_vol_time()".
196        - Implemented built-in script function "change_tune_time()".
197        - Implemented built-in script function "fade_in()".
198        - Implemented built-in script function "fade_out()".
199        - Fixed acceptance of wrong data type of parameters passed to built-in
200          script functions "change_vol()", "change_tune()", "change_pan()",
201          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
202          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
203          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
204        - Added built-in script function "get_event_par()" and implemented some
205          of its possible parameter selections.
206        - Added built-in script function "set_event_par()" and implemented some
207          of its possible parameter selections.
208        - Fixed a bunch of scheduler time related bugs.
209        - Fixed polyphonic variables not being reset to zero after usage.
210        - Built-in "ignore_event()" function: argument is now optional, like with
211          built-in function "ignore_controller()".
212        - Implemented built-in script function "change_velo()".
213        - Implemented built-in script function "change_note()".
214        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
215          intuitive behavior if used in combination with "change_vol_time()" or
216          "change_tune_time()" respectively: now tuning/volume changes are only
217          assigned (without delay) immediately to a new note if the respective
218          timing function has not been called before, otherwise the volume/tuning
219          changes are automatically faded (before, only the event's time stamp was
220          relevant).
221         - Implemented built-in script function "array_equal()".
222         - Implemented built-in script function "search()".
223         - Implemented built-in script function "sort()".
224         - NKSP Fix: Never suspend "init" event handlers.
225         - Implemented built-in script function "same_region()" (currently only
226           available for gig format engine).
227         - Added built-in script constant "$NKSP_LINEAR".
228         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
229         - Implemented built-in script function "change_vol_curve()".
230         - Implemented built-in script function "change_tune_curve()".
231         - built-in "play_note()" function now supports a sample playback start
232           offset with argument 3, where special value -1 means to use the regular
233           sample offset as defined by the instrument file.
234         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
235         - Built-in variable $EVENT_NOTE is now a read-only variable.
236         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
237         - built-in "play_note()" function now accepts -2 for its fourth argument
238           (note duration) which means the life time of the note shall be sticked
239           to the requested note number of argument 1.
240         - Fix: built-in "play_note()" function now returns 0 as result value if
241           -1 was passed for its fourth argument (note duration) and the respective
242           parent note is already gone.
243        - Implemented built-in script function "change_play_pos()".
244        - NKSP language: Added support for user declared const array variables.
245        - NKSP language: Raise parser warning if array variable is accessed with
246          an index that exceeds the array's size.
247        - NKSP language fix: Unknown characters were not handled correctly.
248        - NKSP language: Added support for "synchronized .. end synchronized"
249          code blocks.
250        - Implemented built-in script function "abort()" which allows to abort
251          another script handler by passing its callback ID.
252        - Fixed potential memory access bug and potential undefined behavior of
253          "init" event handlers.
254        - Print a time stamp along to each call of built-in function "message()".
255        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
256          to retrieve all code blocks filtered out by the preprocessor.
257        - Added built-in script function "fork()".
258        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
259        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
260        - Fixed potential crash when accessing dynamic built-in array variables.
261        - Added built-in script function "callback_status()".
262        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
263        - Added built-in constant $CALLBACK_STATUS_QUEUE.
264        - Added built-in constant $CALLBACK_STATUS_RUNNING.
265        - Removed max. value limitation of built-in functions "change_attack()",
266          "change_decay()" and "change_release()" to i.e. allow passing 2000000
267          for doubling the respective time.
268        - NKSP script editor syntax highlighting API: Fixed app termination due
269          to a lexer start condition stack underrun.
270        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
271          USE_CODE_IF_NOT() preprocessor statements.
272        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
273          can be set to disable all subsequent built-in "message()" function calls
274          on preprocessor level.
275        - Implemented built-in script function "change_sustain()".
276        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
277          to avoid the editor app to crash on ill-formed text input.
278        - Added built-in script function "change_pan_time()".
279        - Added built-in script function "change_pan_curve()".
280        - Added built-in script function "change_cutoff_attack()".
281        - Added built-in script function "change_cutoff_decay()".
282        - Added built-in script function "change_cutoff_sustain()".
283        - Added built-in script function "change_cutoff_release()".
284        - Added built-in script function "change_cutoff_lfo_depth()".
285        - Added built-in script function "change_cutoff_lfo_freq()".
286

288        - Fixed memory access bug of general DB access code which lead to
289          undefined behavior.
290        - Cleanup of instruments DB file creation and opening code.
291        - The instrument DB path of linuxsampler's --create-instruments-db argument
292          is now optional, if it is missing, then a default location is used.
293        - Added support for scanning SFZ (.sfz) files.
294        - Added support for scanning Sound Font (.sf2) files.
295        - Fixed undefined DB transaction behavior.
