# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * general changes:
4        - Fixed compiler error in Pool.h.
5        - Require C++14 compiler support.
6        - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7          for checking in configure for C++14 support (as mandatory
8          requirement) and automatically adds compiler argument if required
9          (e.g. -std=C++14).
10        - RTMath: Implemented floating point comparison methods
11          fEqual32(float,float) and fEqual64(double,double) which take the
12          expected floating point tolerances into account.
13        - Added public API C++ class "LFO", which is a cluster class encapsulating
14          all the sampler's LFO implementations to be used by 3rd party applications
15          (e.g. by Gigedit).
16        - Added int math square LFO implementation.
17        - Added int math saw LFO implementation.
18        - Added numeric complex nr sine LFO implementation.
19        - Marked class LFOTriangleDiHarmonic as deprecated
20          (will be removed in future).
21        - Added LFOAll.h which includes all LFO implementation's header files.
22    
23      * Real-time instrument scripts:
24        - Added method ScriptVM::setExitResultEnabled() which allows to
25          explicitly enable the built-in exit() function to optionally accept
26          one function argument; the value of the passed exit() function
27          argument will then become available by calling
28          VMExecContext::exitResult() after script execution.
29        - 64 bit support for NKSP integer scripts variables (declare $foo).
30        - Variable names, function names and preprocessor condition names must start
31          with a regular character (a-z or A-Z); starting them with a digit or
32          underscore is not allowed.
33        - NKSP parser fix: equal comparison operator "=" and not equal comparison
34          operator "#" must only accept integer operands.
35        - NKSP language: Implemented support for standard units like Hertz, seconds,
36          Bel including support for metric unit prefixes; so one can now e.g.
37          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
38          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
39          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
40        - NKSP language: Introduced "final" operator "!" which is specifically
41          intended for synthesis parameter values to denote that the synthesis
42          parameter value is intended to be the "final" value for that synthesis
43          parameter that should explicitly be used by the engine and thus causing
44          the sampler engine to ignore all other modulation sources for the same
45          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
46          variable or formula with this new "!" operator the expression is marked as
47          being "final".
48        - NKSP script editor API: Added support for detecting standard unit tokens
49          and their potential metric prefix token.
50        - NKSP language: Added support for NKSP real number literals and
51          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
52        - NKSP language: Added support for NKSP real number (floating point) script
53          variables (declare ~foo).
54        - NKSP language: Added support for NKSP real number (floating point) array
55          script variables (declare ?foo[]).
56        - Built-in script function "message()" accepts now real number argument as
57          well.
58        - Added built-in script function "real_to_int()" and its short hand form
59          "int()" for casting from real number to integer in NKSP scripts.
60        - Added built-in script function "int_to_real()" and its short hand form
61          "real()" for casting from integer to real number in NKSP scripts.
62        - Allow built-in exit() function to potentially accept real number type
63          argument as well.
64        - Built-in script functions may have a different return type depending on
65          the arguments passed to the function.
66        - Built-in script function "abs()" optionally accepts and returns real
67          number.
68        - Built-in script functions "min()" and "max()" optionally accept real
69          number arguments and return real number as result in that case.
70        - NKSP VM API: Allow units and 'final'ness to be returned as result from
71          built-in functions (added methods VMFunction::returnUnitType() and
72          VMFunction::returnsFinal() for that purpose which must be implemented by
73          built-in function implementations).
74        - NKSP language: Allow metric unit prefixes of numeric scalar and array
75          variables to be changed freely at runtime (unlike unit types like Hz etc.
76          which are still sticky, parse-time features of variables which cannot be
77          changed at runtime for the intentional sake of determinism).
78        - NKSP language: 'final' values are prohibited for array variables for now
79          (attempt causes a parsers error).
80        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
81          conditions of runtime control structures like if(), while(), select()
82          (attempt causes a parser error).
83        - NKSP VM API: Allow built-in functions to perform their own, individual
84          parse time checks of arguments going to be passed to the function at
85          runtime (added method VMFunction::checkArgs() for that purpose).
86        - NKSP language: raise parser warning if only one operand of binary
87          operators (like logical 'or' comparison) contain a 'final' value (because
88          it would always yield in a 'final' result in such cases).
89        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
90          different metric unit prefixes, which will behave as expected (e.g.
91          result of expression '1000us < 2ms' is true).
92        - NKSP language: Allow adding values with different metric unit prefixes
93          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
94        - NKSP language: Allow subtracting values with different metric unit
95          prefixes (e.g. result of expression '1ms - 20us' is '980us').
96        - NKSP language: Allow multiplying with any metric unit prefixes
97          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
98          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
99          we don't have any considerable practical use for a term like '4s^2'
100          (hence any attempt multiplying two unit types still causes parser error).
101        - NKSP language: Allow dividing by any metric unit prefixes and allow
102          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
103          yields in unit free result '8'). So this is now a way to cast units away
104          e.g. for passing the result to other expressions, certain function calls
105          or variables which are not accepting any units (or that specific unit).
106        - NKSP language: integer arrays and real number arrays can now be converted
107          to strings (e.g. for dumping their content with message() calls for
108          script debugging purposes).
109        - NKSP language: expressions and variables with units are now correctly
110          casted to strings (e.g. with message() calls).
111        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
112          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
113          floating point tolerances into account.
114        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
115          VMScalarNumberExpr::evalCastReal().
116        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
117          'VMIntArrayExpr' and 'VMRealArrayExpr'.
118        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
119          unitFactor() (runtime) methods.
120        - Built-in function "exit()" supports now returning units and 'final'ness
121          for test cases.
122        - The following built-in functions support now units as well: "abs()",
123          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
124          "real_to_int()", "int()", "int_to_real()" and "real()".
125        - Built-in functions "array_equal()", "search()" and "sort()" support now
126          real number arrays (correctly) as well.
127        - Added individual parse time checks of arguments to be passed to built-in
128          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
129          "array_equal()" and "search()" specific for their individual purposes.
130        - NKSP VM refactoring: Renamed all methods, functions and classes matching
131          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
132          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
133          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
134          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
135          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
136          isScalarNumber() -> isNumber()).
137        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
138          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
139          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
140          as convenient methods for automatically converting values to expected
141          metric value basis.
142        - Built-in function "wait()" accepts now both integers and real numbers as
143          argument.
144        - NKSP VM API cleanup: Get rid of legacy method
145          VMFunction::argType(vmint iArg) which was already superseded by its new
146          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
147        - NKSP parser: if wrong argument type was passed to a built-in function and
148          that built-in function accepts more than one data type for the argument,
149          then show all supported data types as parser error message.
150        - Built-in function "play_note()" accepts now real numbers and seconds as
151          unit type as well for its 3rd and 4th function arguments.
152        - The following built-in functions accept now real numbers as well for their
153          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
154          "change_attack()", "change_decay()", "change_release()",
155          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
156          "change_cutoff_sustain()", "change_cutoff_release()",
157          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
158          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
159          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
160        - Fixed built-in function "change_play_pos()" not having accepted metric
161          prefixes at all.
162        - Fixed the following built-in functions having misinterpreted values given
163          with unit type (for their 2nd argument) as if they were relative values
164          (that is as if they were passed without a unit type): "change_attack()",
165          "change_decay()", "change_release()", "change_cutoff_attack()",
166          "change_cutoff_decay()", "change_cutoff_release()".
167        - Fixed the following built-in functions having applied completely wrong
168          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
169          respective EGs being their modulation sink assume uint data type with
170          value range 0..1000 instead of 0.0..1.0.
171        - Added individual parse-time checks of function arguments for the following
172          built-in functions: "play_note()", "note_off()", "set_event_mark()",
173          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
174          "change_decay()", "change_release()", "change_cutoff_attack()",
175          "change_cutoff_decay()", "change_cutoff_release()",
176          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
177          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
178          "change_pan_time()".
179        - Don't abort function call if unit type was used and at the same time
180          'final' operator was omitted for the primary value argument of the
181          following built-in functions: "change_cutoff()", "change_attack()",
182          "change_decay()", "change_release()", "change_cutoff_attack()",
183          "change_cutoff_decay()", "change_cutoff_release()",
184          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
185          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
186          "change_pan_time()", instead imply 'final'ness at runtime and raise an
187          appropriate parser warning at parse time.
188        - Added built-in real number functions "round()", "ceil()", "floor()",
189          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
190          "cos()", "tan()", "asin()", "acos()", "atan()".
191        - Added built-in script real number constant "~NI_MATH_PI".
192        - Added built-in script real number constant "~NI_MATH_E".
193        - NKSP language: Allow unary '+' operator.
194    
195      * test cases:
196        - Fixed compiler errors in test cases.
197        - Updated README for how to compile & run test cases.
198        - Updated test case
199          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
200          expected behaviour of the Mutex class implementation (recursive
201          mutex type).
202        - Added test cases for NKSP core language aspects and core built-in
203          functions.
204        - Fixed thread tests segfaulting on Linux.
205        - NKSP: Added real number test cases for built-in functions exit(),
206          int_to_real(), real(), real_to_int() and int(), as well as for the
207          plus, minus and negate language operators.
208        - Added massive amount of NKSP test cases for standard measuring units and
209          'final' operator usage cases.
210        - Added NKSP test cases for (floating point tolerance aware) real number
211          equalness / unequalness comparison.
212        - Added NKSP int array and real array tests for value assignment and
213          initialization of arrays.
214        - Added NKSP test cases for built-in functions "round()", "ceil()",
215          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
216          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
217        - Added NKSP test cases for unary '+' operator.
218    
219      * GigaStudio/Gigasampler format engine:
220        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
221          behaviour for start_level_mid.
222    
223      * SFZ format engine:
224        - Fixed support for regions with loccN/hiccN conditions on more than one
225          MIDI controller.
226    
227      * Benchmarks:
228        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
229          algorithm (since result of 2nd run was not accumulated).
230        - Added benchmark for saw wave (benchmarks/saw.cpp).
231        - Added benchmark for sine wave (benchmarks/sine.cpp).
232        - Added benchmark for square wave (benchmarks/square.cpp).
233        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
234          which are large enough on modern systems.
235    
236    Version 2.1.1 (27 Jul 2019)
237    
238      * Real-time instrument scripts:
239        - Fixed behavior of built-in NKSP functions change_sustain(),
240          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
241          and change_cutoff_release().
242    
243      * general changes:
244        - Only play release trigger samples on sustain pedal up if this behaviour
245          was explicitly requested by the instrument (otherwise only on note-off).
246        - Fixed compiler warnings.
247        - Fixed compilation error when cross-compiling to Mac.
248        - FX Sends: Provide more useful error messages on routing problems
249          (see bug #169).
250        - LSCP doc: Be more clear describing the two distinct approaches
251          of using external vs. internal effects (see bug #169).
252        - "optional" class: Fixed comparison operators.
253    
254      * Gigasampler/GigaStudio format engine:
255        - Format extension: If requested by instrument then don't play release
256          trigger sample on note-off events.
257    
258      * SFZ format engine:
259        - Fixed memory leak when releasing samples
260          (fixes bug #307, patch by Jacek Roszkowski)
261        - Fixed potential crash when a sample is shared by more than one region
262          (fixes bug #308, patch by Jacek Roszkowski).
263        - Opcode 'sample': Added support for built-in sample '*silence'
264          (fixes bug #310, patch by Jacek Roszkowski).
265    
266    Version 2.1.0 (25 Nov 2017)
267    
268      * SFZ format engine:
269        - added support for <global>, <master> and #define (patch by Alby M)
270        - Removed code duplication in SFZ file loading code.
271        - Added support for sfz extension opcode 'script' which may be used to
272          load real-time instrument script file (NKSP script language).
273        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
274        - Fixed unintended volume fade-in of voices under certain conditions.
275        - sfz parser: allow missing space between header and opcode
276    
277      * Gigasampler/GigaStudio format engine:
278        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
279          cutoff settings.
280        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
281          all if an up-pitch of more than 40 semi tones was requested (I don't
282          think there is any stock gig sound that requires this behavior to
283          resemble its original sound).
284        - Added support for controlling whether the individual EGADSR stages may
285          be aborted (as LinuxSampler extension to the original GigaStudio 4
286          format).
287    
288      * general changes:
289        - fixed printf type errors (mostly in debug messages)
290        - use unique_ptr instead of auto_ptr when building with C++11
291        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
292          allowing to sort data efficiently in real-time safe manner.
293        - RTList class: added methods for moving/inserting elements to arbitrary
294          position within a list.
295        - RTList class: added method fromPtr() for creating an Iterator object from
296          a raw element pointer.
297        - Attempt to partly fix resetting engine channels vs. resetting engine, an
298          overall cleanup of the Reset*(), ConnectAudioDevice(),
299          DisconnectAudioDevice() API methods would still be desirable though,
300          because the current situation is still inconsistent and error prone.
301        - Active voices are now internally grouped to "Note" objects, instead of
302          being directly assigned to a keyboard key. This allows more fine graded
303          processing of voices, which is i.e. required for certain instrument
304          script features.
305        - Fix: Release trigger voices were not spawned on sustain pedal up
306          (CC #64) events.
307        - Fix: Release trigger voices can now also distinguish correctly between
308          note-off and sustain pedal up events.
309        - All engines: Increased ramp speed of volume smoother and pan smoother
310          (while slow rate of crossfade smoother is preserved) to allow quick
311          volume and pan changes by instrument scripts for instance.
312        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
313          properly and thus were ignored for certain uses.
314        - Added new C++ API method
315          VirtualMidiDevice::SendChannelPressureToSampler().
316        - windows, 32-bit: fixed potential crashes by making sure the stack in
317          sub threads is 16-byte aligned
318        - fixed numerous compiler warnings
319        - Fixed invalid (note-on) event ID being assigned to new Note objects.
320        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
321          fixes potential undefined behavior.
322        - Fixed Note object leak when triggering notes on keys which did not
323          have a valid sample mapped (fixes bug #252).
324        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
325        - linuxsampler binary fix: option --create-instruments-db ignored
326          subsequent optional argument due to glibc's implementation oddity
327          which expects a "=" sign, but no space between them.
328    
329      * packaging changes:
330        - removed unnecessary dependency to libuuid
331          (originated by libgig's usage of it)
332        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
333          auto detect whether it (sh/c)ould output its messages in color.
334        - Debian: Fixed packaging error about invalid "Source-Version"
335          substitution variable.
336        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
337        - Debian: Added build dependency to libsqlite3-dev for building
338          linuxsampler with instruments DB support.
339    
340      * Real-time instrument scripts:
341        - Implemented scheduler for delayed MIDI events and for suspended scripts.
342        - Built-in script function "wait()": implemented support for function's
343          "duration-us" argument, thus scripts using this function are now
344          correctly resumed after the requested amount of microseconds.
345        - Built-in script function "play_note()": implemented support for
346          function's "duration-us" argument, thus notes triggered with this
347          argument are now correctly released after the requested amount of
348          microseconds.
349        - Fix: script events were not cleared when engine channel was reset,
350          potentially causing undefined behavior.
351        - Fixed crash which happened when trying to reference an undeclared
352          variable.
353        - Built-in script function "play_note()": Added support for passing

378          and ".not.".
379        - NKSP language scanner: Fixed IDs matching to require at least one
380          character (i.e. when matching function names or variable names).
381        - NKSP language scanner: disabled unusued rules.
382        - Fixed behavior of play_note() and note_off() functions which must
383          be distinguished engine internally from "real" MIDI note on/off
384          events in order to avoid misbehaviors like hanging notes.

411          synthesis parameter changes immediately in case the respective note
412          was triggered at the same time, instead of scheduling the parameter
413          change, especially because it would cause some parameter types's
414          changes either to be ramped (i.e. change_vol()) or other types even
415          to have not effect at all (i.e. change_attack()).

420        - NKSP Fix: "init" event handler was not always executed when a script
421          was loaded.
422        - NKSP built-in wait() script function: abort script execution if
423          a negative or zero wait time was passed as argument (since this is
424          a common indication of a bug either of the script or even of the
425          engine, which could lead to RT instability or even worse).
426        - ScriptVM: Implemented automatic suspension of RT safety
427          threatening scripts.
428        - Provide more user friendly error messages on syntax errors.

442          script functions "change_vol()", "change_tune()", "change_pan()",
443          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
444          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
445          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
446        - Added built-in script function "get_event_par()" and implemented some
447          of its possible parameter selections.
448        - Added built-in script function "set_event_par()" and implemented some
449          of its possible parameter selections.
450        - Fixed a bunch of scheduler time related bugs.
451        - Fixed polyphonic variables not being reset to zero after usage.
452        - Built-in "ignore_event()" function: argument is now optional, like with

454        - Implemented built-in script function "change_velo()".
455        - Implemented built-in script function "change_note()".
456        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
457          intuitive behavior if used in combination with "change_vol_time()" or
458          "change_tune_time()" respectively: now tuning/volume changes are only
459          assigned (without delay) immediately to a new note if the respective
460          timing function has not been called before, otherwise the volume/tuning
461          changes are automatically faded (before, only the event's time stamp was
462          relevant).
463         - Implemented built-in script function "array_equal()".
464         - Implemented built-in script function "search()".
465         - Implemented built-in script function "sort()".
466         - NKSP Fix: Never suspend "init" event handlers.
467         - Implemented built-in script function "same_region()" (currently only
468           available for gig format engine).
469         - Added built-in script constant "$NKSP_LINEAR".
470         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
471         - Implemented built-in script function "change_vol_curve()".

473         - built-in "play_note()" function now supports a sample playback start
474           offset with argument 3, where special value -1 means to use the regular
475           sample offset as defined by the instrument file.
476         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
477         - Built-in variable $EVENT_NOTE is now a read-only variable.
478         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
479         - built-in "play_note()" function now accepts -2 for its fourth argument
480           (note duration) which means the life time of the note shall be sticked
481           to the requested note number of argument 1.
482         - Fix: built-in "play_note()" function now returns 0 as result value if
483           -1 was passed for its fourth argument (note duration) and the respective
484           parent note is already gone.
485        - Implemented built-in script function "change_play_pos()".
