This allows more fine graded + processing of voices, which is i.e. required for certain instrument + script features. + - Fix: Release trigger voices were not spawned on sustain pedal up + (CC #64) events. + - Fix: Release trigger voices can now also distinguish correctly between + note-off and sustain pedal up events. + - All engines: Increased ramp speed of volume smoother and pan smoother + (while slow rate of crossfade smoother is preserved) to allow quick + volume and pan changes by instrument scripts for instance. + - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed + properly and thus were ignored for certain uses. + - Added new C++ API method + VirtualMidiDevice::SendChannelPressureToSampler(). + - windows, 32-bit: fixed potential crashes by making sure the stack in + sub threads is 16-byte aligned + - fixed numerous compiler warnings + - Fixed invalid (note-on) event ID being assigned to new Note objects. + - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which + fixes potential undefined behavior. + - Fixed Note object leak when triggering notes on keys which did not + have a valid sample mapped (fixes bug #252). + - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled. + - linuxsampler binary fix: option --create-instruments-db ignored + subsequent optional argument due to glibc's implementation oddity + which expects a "=" sign, but no space between them. + + * packaging changes: + - removed unnecessary dependency to libuuid + (originated by libgig's usage of it) + - Automake: set environment variable GCC_COLORS=auto to allow GCC to + auto detect whether it (sh/c)ould output its messages in color. + - Debian: Fixed packaging error about invalid "Source-Version" + substitution variable. + - Debian: Raised Debian compatibility level to Debian 9 "Stretch". + - Debian: Added build dependency to libsqlite3-dev for building + linuxsampler with instruments DB support. + + * Real-time instrument scripts: + - Implemented scheduler for delayed MIDI events and for suspended scripts. + - Built-in script function "wait()": implemented support for function's + "duration-us" argument, thus scripts using this function are now + correctly resumed after the requested amount of microseconds. + - Built-in script function "play_note()": implemented support for + function's "duration-us" argument, thus notes triggered with this + argument are now correctly released after the requested amount of + microseconds. + - Fix: script events were not cleared when engine channel was reset, + potentially causing undefined behavior. + - Fixed crash which happened when trying to reference an undeclared + variable. + - Built-in script function "play_note()": Added support for passing + special value -1 for "duration-us" argument, which will cause the + triggered note to be released once the original note was released. + - Instrument script classes now exported with the liblinuxsampler C++ API. + - Added new API method ScriptVM::syntaxHighlighting() which provides + a convenient syntax highlighting backend for external instrument + script editor applications. + - Added new C++ API class "ScriptVMFactory". + - Extended parser issues to provide not only first line and first + column, but also last line and last column of issue (thus marking + the precise span of the issue within the source code). + - Reload script automatically after being modified by an instrument + editor. + - NKSP language grammar correction: allow empty event handler bodies + like "on note end on". + - Implemented built-in script function "change_vol()". + - Implemented built-in script function "change_tune()". + - Implemented built-in script function "change_pan()". + - Implemented built-in script function "change_cutoff()". + - Implemented built-in script function "change_reso()". + - Implemented built-in script function "event_status()". + - Added built-in script constants "$EVENT_STATUS_INACTIVE" and + "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for + "event_status()" function. + - NKSP language: Added support for bitwise operators ".or.", ".and." + and ".not.". + - NKSP language scanner: Fixed IDs matching to require at least one + character (i.e. when matching function names or variable names). + - NKSP language scanner: disabled unusued rules. + - Fixed behavior of play_note() and note_off() functions which must + be distinguished engine internally from "real" MIDI note on/off + events in order to avoid misbehaviors like hanging notes. + - Implemented built-in script variable "$KSP_TIMER". + - Implemented built-in script variable "$NKSP_REAL_TIMER". + - Implemented built-in script variable "$NKSP_PERF_TIMER". + - Implemented built-in script variable "$ENGINE_UPTIME". + - Implemented built-in script function "inc()". + - Implemented built-in script function "dec()". + - NKSP language fix: division expressions were evaluated too often. + - NKSP language fix: string concatenation operator was right + associative instead of left (to right). + - NKSP language correction: allow empty statements in entire language + (i.e. "if end if"). + - Implemented built-in script function "stop_wait()". + - Implemented built-in script variable "$NI_CALLBACK_ID". + - Implemented built-in script variable "$NI_CALLBACK_TYPE". + - Implemented built-in script variable "$NKSP_IGNORE_WAIT". + - Added support for read-only built-in variables (respectively + handled by the script parser). + -

NKSP Language: Added support for user defined script functions. + - Implemented built-in script function "change_attack()". + - Implemented built-in script function "change_decay()". + - Implemented built-in script function "change_release()". + - Fixed all change_*() built-in script functions to apply their + synthesis parameter changes immediately in case the respective note + was triggered at the same time, instead of scheduling the parameter + change, especially because it would cause some parameter types's + changes either to be ramped (i.e. change_vol()) or other types even + to have not effect at all (i.e. change_attack()). + - Implemented built-in script function "sh_left()". + - Implemented built-in script function "sh_right()". + - Implemented built-in script function "min()". + - Implemented built-in script function "max()". + - NKSP Fix: "init" event handler was not always executed when a script + was loaded. + - NKSP built-in wait() script function: abort script execution if + a negative or zero wait time was passed as argument (since this is + a common indication of a bug either of the script or even of the + engine, which could lead to RT instability or even worse). + - ScriptVM: Implemented automatic suspension of RT safety + threatening scripts. + - Provide more user friendly error messages on syntax errors. + - Fixed NKSP parser warning "Not a statement" when assigning an + initializer list to an array variable. + - Implemented built-in script array variable "%ALL_EVENTS". + - Implemented built-in script function "in_range()". + - Implemented built-in script function "change_amp_lfo_depth()". + - Implemented built-in script function "change_amp_lfo_freq()". + -

Implemented built-in script function "fade_in()". + - Implemented built-in script function "fade_out()". + - Fixed acceptance of wrong data type of parameters passed to built-in + script functions "change_vol()", "change_tune()", "change_pan()", + "change_cutoff()", "change_reso()", "change_attack()", "change_decay()", + "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()", + "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()". + - Added built-in script function "get_event_par()" and implemented some + of its possible parameter selections. + - Added built-in script function "set_event_par()" and implemented some + of its possible parameter selections. + - Fixed a bunch of scheduler time related bugs. + - Fixed polyphonic variables not being reset to zero after usage. + - Built-in "ignore_event()" function: argument is now optional, like with + built-in function "ignore_controller()". + - Implemented built-in script function "change_velo()". + - Implemented built-in script function "change_note()". + - Adjusted behavior of "change_vol()" and "change_tune()" to a more + intuitive behavior if used in combination with "change_vol_time()" or + "change_tune_time()" respectively: now tuning/volume changes are only + assigned (without delay) immediately to a new note if the respective + timing function has not been called before, otherwise the volume/tuning + changes are automatically faded (before, only the event's time stamp was + relevant). + - Implemented built-in script function "array_equal()". + - Implemented built-in script function "search()". + - Implemented built-in script function "sort()". + - NKSP Fix: Never suspend "init" event handlers. + - Implemented built-in script function "same_region()" (currently only + available for gig format engine). + - Added built-in script constant "$NKSP_LINEAR". + - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT". + - Implemented built-in script function "change_vol_curve()". + - Implemented built-in script function "change_tune_curve()". + - built-in "play_note()" function now supports a sample playback start + offset with argument 3, where special value -1 means to use the regular + sample offset as defined by the instrument file. + - Built-in array variable %KEY_DOWN[] is now a read-only variable. + - Built-in variable $EVENT_NOTE is now a read-only variable. + - Built-in variable $EVENT_VELOCITY is now a read-only variable. + - built-in "play_note()" function now accepts -2 for its fourth argument + (note duration) which means the life time of the note shall be sticked + to the requested note number of argument 1. + - Fix: built-in "play_note()" function now returns 0 as result value if + -1 was passed for its fourth argument (note duration) and the respective + parent note is already gone. + - Implemented built-in script function "change_play_pos()". + - NKSP language: Added support for user declared const array variables. + - NKSP language: Raise parser warning if array variable is accessed with + an index that exceeds the array's size. + - NKSP language fix: Unknown characters were not handled correctly. + - NKSP language: Added support for "synchronized .. end synchronized" + code blocks. + - Implemented built-in script function "abort()" which allows to abort + another script handler by passing its callback ID. + - Fixed potential memory access bug and potential undefined behavior of + "init" event handlers. + - Print a time stamp along to each call of built-in function "message()". + - ScriptVM API: Added VMParserContext::preprocessorComments() which allows + to retrieve all code blocks filtered out by the preprocessor. + - Added built-in script function "fork()". + - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[]. + - Added built-in variable $NKSP_CALLBACK_PARENT_ID. + - Fixed potential crash when accessing dynamic built-in array variables. + - Added built-in script function "callback_status()". + - Added built-in constant $CALLBACK_STATUS_TERMINATED. + - Added built-in constant $CALLBACK_STATUS_QUEUE. + - Added built-in constant $CALLBACK_STATUS_RUNNING. + - Removed max. value limitation of built-in functions "change_attack()", + "change_decay()" and "change_release()" to i.e. allow passing 2000000 + for doubling the respective time. + - NKSP script editor syntax highlighting API: Fixed app termination due + to a lexer start condition stack underrun. + - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and + USE_CODE_IF_NOT() preprocessor statements. + - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which + can be set to disable all subsequent built-in "message()" function calls + on preprocessor level. + - Implemented built-in script function "change_sustain()". + - NKSP script editor syntax highlighting API: catch all fatal lexer errors, + to avoid the editor app to crash on ill-formed text input. + - Added built-in script function "change_pan_time()". + - Added built-in script function "change_pan_curve()". + - Added built-in script function "change_cutoff_attack()". + - Added built-in script function "change_cutoff_decay()". + -
