and likewise added new + *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*() + methods and marked those old ones deprecated as well. + - Added support for MIDI CC #38 (data entry LSB): this allows higher value + resolution for certain (e.g. hard coded) RPN and NRPN parameters. + - Implemented support for compressed RPN/NRPN message sequences (that is to + allow processing MIDI data entry messages without always having to be + preceded strictly by RPN/NRPN parameter selection messages on each value + change). + - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data + decrement). + - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter + MSB=127 and LSB=127) and which is disabling subsequent data + entry/increment/decrement CC messages. + - Fixed crash when editing key groups (a.k.a. exclusive groups) with an + instrument editor. + - Fixed playing noise at the end of a disk stream under certain conditions. + - Fixed potential crash with high pitch at end of RAM playback. + - Added configure checks whether C++ compiler supports so called + 'designated initializers'. + - Added global backtraceAsString() function for debugging purposes + (POSIX systems only, no Windows implementation yet). + - Thread class: Added new methods pushCancelable(), popCancelable(), name(), + nameOfCaller() and setNameOfCaller(). + - configure: Always check for availability of pthread_testcancel() and use + it if so (previously it was only used if explicitly enabled by configure + option). + - Thread class: raise compiler warning if pthread_testcancel() is not + available, because it can lead to deadlocks. + - Mutex class: Implemented optional bug detection and deadlock debugging + features. + - Ref<> class is now thread safe (as lock-free and wait-free + implementation). + - Fixed compilation error with Bison >= 3.6.0. + - Fixed rare crash when switching between instruments that had instrument + scripts loaded. * Real-time instrument scripts: - Added method ScriptVM::setExitResultEnabled() which allows to @@ -182,6 +241,62 @@ - Added built-in script real number constant "~NI_MATH_PI". - Added built-in script real number constant "~NI_MATH_E". - NKSP language: Allow unary '+' operator. + - Added built-in script functions "msb()" and "lsb()". + - NKSP language: Added support for RPN event handler + ("on rpn ... end on" in instrument scripts). + - NKSP language: Added support for NRPN event handler + ("on nrpn ... end on" in instrument scripts). + - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which + may be read from the new RPN/NRPN script handlers to get the (N)RPN + parameter that had been changed and its new value. + - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN" + which are identifying the new (N)RPN handlers as such at script runtime. + - Implemented built-in script function "set_rpn()". + - Implemented built-in script function "set_nrpn()". + - Fix: built-in functions returning an array type were broken and caused a + crash when the built-in function's (supposed to be array) result value was + used by the script VM. + - Removed upper value constraint for 2nd argument of built-in functions + "change_amp_lfo_freq()", "change_cutoff_lfo_freq()", + "change_pitch_lfo_freq()","change_reso()", "change_cutoff()", + "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and + "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double + the LFO frequency / resonance / cutoff frequency. + - Reduced code involved for parsing NKSP variable declarations by using 2 + generalized grammar rules with optional components (i.e. optional value + assignment and optional variable qualifiers) instead of previous linear + combinations of grammar rules, which also fixes some edge case. + - NKSP language parser: track code block locations also by a) raw byte + position in NKSP source code string and b) length of that code block in + bytes (along to the already existing code block tracking by line/column);
