|
* 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 |
|
- Refactored LFO class names and their file names (PulseLFO -> LFOPulse, |
| 23 |
|
LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld, |
| 24 |
|
SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr, |
| 25 |
|
SquareLFO -> LFOSquarePulse and separated the latter to its own header |
| 26 |
|
file). |
| 27 |
|
- Renamed type LFOSigned -> LFOTriangleSigned. |
| 28 |
|
- Renamed type LFOUnsigned -> LFOTriangleUnsigned. |
| 29 |
|
- Using now cubic interpolation as resampling algorithm by default; and |
| 30 |
|
linear interpolation is deprecated now. |
| 31 |
|
- Event:Init(): memset() entire Event::Param union to zero instead of trying |
| 32 |
|
to do that for its individual members; the latter became error prone due |
| 33 |
|
to the union's growing complexity meanwhile. |
| 34 |
|
- EngineChannel: Overhaul of RPN/NRPN related methods: Added new |
| 35 |
|
*Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*() |
| 36 |
|
methods and marked the old ones as deprecated; and likewise added new |
| 37 |
|
*Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*() |
| 38 |
|
methods and marked those old ones deprecated as well. |
| 39 |
|
- Added support for MIDI CC #38 (data entry LSB): this allows higher value |
| 40 |
|
resolution for certain (e.g. hard coded) RPN and NRPN parameters. |
| 41 |
|
- Implemented support for compressed RPN/NRPN message sequences (that is to |
| 42 |
|
allow processing MIDI data entry messages without always having to be |
| 43 |
|
preceded strictly by RPN/NRPN parameter selection messages on each value |
| 44 |
|
change). |
| 45 |
|
- Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data |
| 46 |
|
decrement). |
| 47 |
|
- Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter |
| 48 |
|
MSB=127 and LSB=127) and which is disabling subsequent data |
| 49 |
|
entry/increment/decrement CC messages. |
| 50 |
|
- Fixed crash when editing key groups (a.k.a. exclusive groups) with an |
| 51 |
|
instrument editor. |
| 52 |
|
- Fixed playing noise at the end of a disk stream under certain conditions. |
| 53 |
|
- Fixed potential crash with high pitch at end of RAM playback. |
| 54 |
|
- Added configure checks whether C++ compiler supports so called |
| 55 |
|
'designated initializers'. |
| 56 |
|
- Added global backtraceAsString() function for debugging purposes |
| 57 |
|
(POSIX systems only, no Windows implementation yet). |
| 58 |
|
- Thread class: Added new methods pushCancelable(), popCancelable(), name(), |
| 59 |
|
nameOfCaller() and setNameOfCaller(). |
| 60 |
|
- configure: Always check for availability of pthread_testcancel() and use |
| 61 |
|
it if so (previously it was only used if explicitly enabled by configure |
| 62 |
|
option). |
| 63 |
|
- Thread class: raise compiler warning if pthread_testcancel() is not |
| 64 |
|
available, because it can lead to deadlocks. |
| 65 |
|
- Mutex class: Implemented optional bug detection and deadlock debugging |
| 66 |
|
features. |
| 67 |
|
- Ref<> class is now thread safe (as lock-free and wait-free |
| 68 |
|
implementation). |
| 69 |
|
- Fixed compilation error with Bison >= 3.6.0. |
| 70 |
|
- Fixed rare crash when switching between instruments that had instrument |
| 71 |
|
scripts loaded. |
| 72 |
|
- Allow EffectChain::InsertEffect() as alternative to |
| 73 |
|
EffectChain::AppendEffect() (i.e. with index equal to current chain size). |
| 74 |
|
|
| 75 |
|
* Real-time instrument scripts: |
| 76 |
|
- Added method ScriptVM::setExitResultEnabled() which allows to |
| 77 |
|
explicitly enable the built-in exit() function to optionally accept |
| 78 |
|
one function argument; the value of the passed exit() function |
| 79 |
|
argument will then become available by calling |
| 80 |
|
VMExecContext::exitResult() after script execution. |
| 81 |
|
- 64 bit support for NKSP integer scripts variables (declare $foo). |
| 82 |
|
- Variable names, function names and preprocessor condition names must start |
| 83 |
|
with a regular character (a-z or A-Z); starting them with a digit or |
| 84 |
|
underscore is not allowed. |
| 85 |
|
- NKSP parser fix: equal comparison operator "=" and not equal comparison |
| 86 |
|
operator "#" must only accept integer operands. |
| 87 |
|
- NKSP language: Implemented support for standard units like Hertz, seconds, |
| 88 |
|
Bel including support for metric unit prefixes; so one can now e.g. |
| 89 |
|
conveniently use numbers in scripts like "5us" meaning "5 microseconds", |
| 90 |
|
or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning |
| 91 |
|
"minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning). |
| 92 |
|
- NKSP language: Introduced "final" operator "!" which is specifically |
| 93 |
|
intended for synthesis parameter values to denote that the synthesis |
| 94 |
|
parameter value is intended to be the "final" value for that synthesis |
| 95 |
|
parameter that should explicitly be used by the engine and thus causing |
| 96 |
|
the sampler engine to ignore all other modulation sources for the same |
| 97 |
|
synthesis parameter (like e.g. LFO, EG); by simply prefixing a value, |
| 98 |
|
variable or formula with this new "!" operator the expression is marked as |
| 99 |
|
being "final". |
| 100 |
|
- NKSP script editor API: Added support for detecting standard unit tokens |
| 101 |
|
and their potential metric prefix token. |
| 102 |
|
- NKSP language: Added support for NKSP real number literals and |
| 103 |
|
arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0"). |
| 104 |
|
- NKSP language: Added support for NKSP real number (floating point) script |
| 105 |
|
variables (declare ~foo). |
| 106 |
|
- NKSP language: Added support for NKSP real number (floating point) array |
| 107 |
|
script variables (declare ?foo[]). |
| 108 |
|
- Built-in script function "message()" accepts now real number argument as |
| 109 |
|
well. |
| 110 |
|
- Added built-in script function "real_to_int()" and its short hand form |
| 111 |
|
"int()" for casting from real number to integer in NKSP scripts. |
| 112 |
|
- Added built-in script function "int_to_real()" and its short hand form |
| 113 |
|
"real()" for casting from integer to real number in NKSP scripts. |
| 114 |
|
- Allow built-in exit() function to potentially accept real number type |
| 115 |
|
argument as well. |
| 116 |
|
- Built-in script functions may have a different return type depending on |
| 117 |
|
the arguments passed to the function. |
| 118 |
|
- Built-in script function "abs()" optionally accepts and returns real |
| 119 |
|
number. |
| 120 |
|
- Built-in script functions "min()" and "max()" optionally accept real |
| 121 |
|
number arguments and return real number as result in that case. |
| 122 |
|
- NKSP VM API: Allow units and 'final'ness to be returned as result from |
| 123 |
|
built-in functions (added methods VMFunction::returnUnitType() and |
| 124 |
|
VMFunction::returnsFinal() for that purpose which must be implemented by |
| 125 |
|
built-in function implementations). |
| 126 |
|
- NKSP language: Allow metric unit prefixes of numeric scalar and array |
| 127 |
|
variables to be changed freely at runtime (unlike unit types like Hz etc. |
| 128 |
|
which are still sticky, parse-time features of variables which cannot be |
| 129 |
|
changed at runtime for the intentional sake of determinism). |
| 130 |
|
- NKSP language: 'final' values are prohibited for array variables for now |
| 131 |
|
(attempt causes a parsers error). |
| 132 |
|
- NKSP language: expressions with unit types (e.g. Hz) are prohibited for |
| 133 |
|
conditions of runtime control structures like if(), while(), select() |
| 134 |
|
(attempt causes a parser error). |
| 135 |
|
- NKSP VM API: Allow built-in functions to perform their own, individual |
| 136 |
|
parse time checks of arguments going to be passed to the function at |
| 137 |
|
runtime (added method VMFunction::checkArgs() for that purpose). |
| 138 |
|
- NKSP language: raise parser warning if only one operand of binary |
| 139 |
|
operators (like logical 'or' comparison) contain a 'final' value (because |
| 140 |
|
it would always yield in a 'final' result in such cases). |
| 141 |
|
- NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with |
| 142 |
|
different metric unit prefixes, which will behave as expected (e.g. |
| 143 |
|
result of expression '1000us < 2ms' is true). |
| 144 |
|
- NKSP language: Allow adding values with different metric unit prefixes |
| 145 |
|
(e.g. result of expression '100Hz + 5kHz' is '5100Hz'). |
| 146 |
|
- NKSP language: Allow subtracting values with different metric unit |
| 147 |
|
prefixes (e.g. result of expression '1ms - 20us' is '980us'). |
| 148 |
|
- NKSP language: Allow multiplying with any metric unit prefixes |
| 149 |
|
(e.g. result of expression '2k * 3ms' is '6s'), however multiplications |
| 150 |
|
with unit types on both sides (e.g. '2s * 2s') is still prohibited since |
| 151 |
|
we don't have any considerable practical use for a term like '4s^2' |
| 152 |
|
(hence any attempt multiplying two unit types still causes parser error). |
| 153 |
|
- NKSP language: Allow dividing by any metric unit prefixes and allow |
| 154 |
|
division of same unit type on both sides (e.g. expression '8kHz / 1000Hz' |
| 155 |
|
yields in unit free result '8'). So this is now a way to cast units away |
| 156 |
|
e.g. for passing the result to other expressions, certain function calls |
| 157 |
|
or variables which are not accepting any units (or that specific unit). |
| 158 |
|
- NKSP language: integer arrays and real number arrays can now be converted |
| 159 |
|
to strings (e.g. for dumping their content with message() calls for |
| 160 |
|
script debugging purposes). |
| 161 |
|
- NKSP language: expressions and variables with units are now correctly |
| 162 |
|
casted to strings (e.g. with message() calls). |
| 163 |
|
- NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or |
| 164 |
|
unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected |
| 165 |
|
floating point tolerances into account. |
| 166 |
|
- NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and |
| 167 |
|
VMScalarNumberExpr::evalCastReal(). |
| 168 |
|
- NKSP VM API: Added base class 'VMNumberArrayExpr' for classes |
| 169 |
|
'VMIntArrayExpr' and 'VMRealArrayExpr'. |
| 170 |
|
- NKSP VM API: replaced all unitPrefix() (parse time) methods by |
| 171 |
|
unitFactor() (runtime) methods. |
| 172 |
|
- Built-in function "exit()" supports now returning units and 'final'ness |
| 173 |
|
for test cases. |
| 174 |
|
- The following built-in functions support now units as well: "abs()", |
| 175 |
|
"random()", "inc()", "dec()", "in_range()", "min()", "max()", |
| 176 |
|
"real_to_int()", "int()", "int_to_real()" and "real()". |
| 177 |
|
- Built-in functions "array_equal()", "search()" and "sort()" support now |
| 178 |
|
real number arrays (correctly) as well. |
| 179 |
|
- Added individual parse time checks of arguments to be passed to built-in |
| 180 |
|
functions "random()", "inc()", "dec()", "in_range()", "min()", "max()", |
| 181 |
|
"array_equal()" and "search()" specific for their individual purposes. |
| 182 |
|
- NKSP VM refactoring: Renamed all methods, functions and classes matching |
| 183 |
|
pattern *ScalarNumber* to simply *Number* (that is i.e. classes |
| 184 |
|
VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr, |
| 185 |
|
ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp -> |
| 186 |
|
NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction, |
| 187 |
|
method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function |
| 188 |
|
isScalarNumber() -> isNumber()). |
| 189 |
|
- NKSP VM API: Added 4 overridden methods to class VMNumberExpr: |
| 190 |
|
evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t), |
| 191 |
|
evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t) |
| 192 |
|
as convenient methods for automatically converting values to expected |
| 193 |
|
metric value basis. |
| 194 |
|
- Built-in function "wait()" accepts now both integers and real numbers as |
| 195 |
|
argument. |
| 196 |
|
- NKSP VM API cleanup: Get rid of legacy method |
| 197 |
|
VMFunction::argType(vmint iArg) which was already superseded by its new |
| 198 |
|
replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type). |
| 199 |
|
- NKSP parser: if wrong argument type was passed to a built-in function and |
| 200 |
|
that built-in function accepts more than one data type for the argument, |
| 201 |
|
then show all supported data types as parser error message. |
| 202 |
|
- Built-in function "play_note()" accepts now real numbers and seconds as |
| 203 |
|
unit type as well for its 3rd and 4th function arguments. |
| 204 |
|
- The following built-in functions accept now real numbers as well for their |
| 205 |
|
2nd function argument: "change_vol()", "change_tune()", "change_cutoff()", |
| 206 |
|
"change_attack()", "change_decay()", "change_release()", |
| 207 |
|
"change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()", |
| 208 |
|
"change_cutoff_sustain()", "change_cutoff_release()", |
| 209 |
|
"change_amp_lfo_freq()", "change_cutoff_lfo_freq()", |
| 210 |
|
"change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()", |
| 211 |
|
"change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()". |
| 212 |
|
- Fixed built-in function "change_play_pos()" not having accepted metric |
| 213 |
|
prefixes at all. |
| 214 |
|
- Fixed the following built-in functions having misinterpreted values given |
| 215 |
|
with unit type (for their 2nd argument) as if they were relative values |
| 216 |
|
(that is as if they were passed without a unit type): "change_attack()", |
| 217 |
|
"change_decay()", "change_release()", "change_cutoff_attack()", |
| 218 |
|
"change_cutoff_decay()", "change_cutoff_release()". |
| 219 |
|
- Fixed the following built-in functions having applied completely wrong |
| 220 |
|
'final' values: "change_sustain()", "change_cutoff_sustain()" (since the |
| 221 |
|
respective EGs being their modulation sink assume uint data type with |
| 222 |
|
value range 0..1000 instead of 0.0..1.0. |
| 223 |
|
- Added individual parse-time checks of function arguments for the following |
| 224 |
|
built-in functions: "play_note()", "note_off()", "set_event_mark()", |
| 225 |
|
"delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()", |
| 226 |
|
"change_decay()", "change_release()", "change_cutoff_attack()", |
| 227 |
|
"change_cutoff_decay()", "change_cutoff_release()", |
| 228 |
|
"change_amp_lfo_freq()", "change_cutoff_lfo_freq()", |
| 229 |
|
"change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and |
| 230 |
|
"change_pan_time()". |
| 231 |
|
- Don't abort function call if unit type was used and at the same time |
| 232 |
|
'final' operator was omitted for the primary value argument of the |
| 233 |
|
following built-in functions: "change_cutoff()", "change_attack()", |
| 234 |
|
"change_decay()", "change_release()", "change_cutoff_attack()", |
| 235 |
|
"change_cutoff_decay()", "change_cutoff_release()", |
| 236 |
|
"change_amp_lfo_freq()", "change_cutoff_lfo_freq()", |
| 237 |
|
"change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()", |
| 238 |
|
"change_pan_time()", instead imply 'final'ness at runtime and raise an |
| 239 |
|
appropriate parser warning at parse time. |
| 240 |
|
- Added built-in real number functions "round()", "ceil()", "floor()", |
| 241 |
|
"sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()", |
| 242 |
|
"cos()", "tan()", "asin()", "acos()", "atan()". |
| 243 |
|
- Added built-in script real number constant "~NI_MATH_PI". |
| 244 |
|
- Added built-in script real number constant "~NI_MATH_E". |
| 245 |
|
- NKSP language: Allow unary '+' operator. |
| 246 |
|
- Added built-in script functions "msb()" and "lsb()". |
| 247 |
|
- NKSP language: Added support for RPN event handler |
| 248 |
|
("on rpn ... end on" in instrument scripts). |
| 249 |
|
- NKSP language: Added support for NRPN event handler |
| 250 |
|
("on nrpn ... end on" in instrument scripts). |
| 251 |
|
- Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which |
| 252 |
|
may be read from the new RPN/NRPN script handlers to get the (N)RPN |
| 253 |
|
parameter that had been changed and its new value. |
| 254 |
|
- Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN" |
| 255 |
|
which are identifying the new (N)RPN handlers as such at script runtime. |
| 256 |
|
- Implemented built-in script function "set_rpn()". |
| 257 |
|
- Implemented built-in script function "set_nrpn()". |
| 258 |
|
- Fix: built-in functions returning an array type were broken and caused a |
| 259 |
|
crash when the built-in function's (supposed to be array) result value was |
| 260 |
|
used by the script VM. |
| 261 |
|
- Removed upper value constraint for 2nd argument of built-in functions |
| 262 |
|
"change_amp_lfo_freq()", "change_cutoff_lfo_freq()", |
| 263 |
|
"change_pitch_lfo_freq()","change_reso()", "change_cutoff()", |
| 264 |
|
"change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and |
| 265 |
|
"change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double |
| 266 |
|
the LFO frequency / resonance / cutoff frequency. |
| 267 |
|
- Reduced code involved for parsing NKSP variable declarations by using 2 |
| 268 |
|
generalized grammar rules with optional components (i.e. optional value |
| 269 |
|
assignment and optional variable qualifiers) instead of previous linear |
| 270 |
|
combinations of grammar rules, which also fixes some edge case. |
| 271 |
|
- NKSP language parser: track code block locations also by a) raw byte |
| 272 |
|
position in NKSP source code string and b) length of that code block in |
| 273 |
|
bytes (along to the already existing code block tracking by line/column); |
| 274 |
|
and added appropriate new members to public C++ API classes like |
| 275 |
|
'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock. |
| 276 |
|
- NKSP language: Added support for 'patch' variable qualifier (capture their |
| 277 |
|
locations and allow replacement of their assignment expression via VM C++ |
| 278 |
|
API). |
| 279 |
|
- Fixed incorrect EG times if standard measuring unit was passed to built-in |
| 280 |
|
functions "change_attack()", "change_decay()" or "change_release()". |
| 281 |
|
- Fixed intermediate function result values never having reflected any |
| 282 |
|
standard measuring unit type. |
| 283 |
|
- Fixed re-entrant issue with function calls which caused wrong result |
| 284 |
|
values if the same function was called multiple times in a term |
| 285 |
|
(specifically if metric prefixes were used). |
| 286 |
|
- NKSP language: Just throw a warning, not an error if an array variable of |
| 287 |
|
size zero was declared. |
| 288 |
|
- NKSP language: Allow omitting explicit array size on array variable |
| 289 |
|
declaration if combined with immediate value assignment |
| 290 |
|
(e.g. declare %foo[] := ( 1, 2, 3 ) ). |
| 291 |
|
- NKSP language: emit warning if an array variable was declared with bigger |
| 292 |
|
array size than amount of initial values been assigned, and initialize the |
| 293 |
|
missing array elements with zero in this case. |
| 294 |
|
- Fixed built-in NKSP exit() function to behave as return statement. |
| 295 |
|
- NKSP parser: Fixed crash if unary '-' operator was used on a non-number |
| 296 |
|
data type. |
| 297 |
|
- NKSP VM: Fixed the "release" handler being executed too often under |
| 298 |
|
certain situations if polyphonic data was passed from "note" handler to |
| 299 |
|
"release" handler. |
| 300 |
|
- Fixed memory leak in NKSP parser: string tokens were allocated as C |
| 301 |
|
strings and never freed. |
| 302 |
|
|
| 303 |
|
* test cases: |
| 304 |
|
- Fixed compiler errors in test cases. |
| 305 |
|
- Updated README for how to compile & run test cases. |
| 306 |
|
- Updated test case |
| 307 |
|
MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest |
| 308 |
|
expected behaviour of the Mutex class implementation (recursive |
| 309 |
|
mutex type). |
| 310 |
|
- Added test cases for NKSP core language aspects and core built-in |
| 311 |
|
functions. |
| 312 |
|
- Fixed thread tests segfaulting on Linux. |
| 313 |
|
- NKSP: Added real number test cases for built-in functions exit(), |
| 314 |
|
int_to_real(), real(), real_to_int() and int(), as well as for the |
| 315 |
|
plus, minus and negate language operators. |
| 316 |
|
- Added massive amount of NKSP test cases for standard measuring units and |
| 317 |
|
'final' operator usage cases. |
| 318 |
|
- Added NKSP test cases for (floating point tolerance aware) real number |
| 319 |
|
equalness / unequalness comparison. |
| 320 |
|
- Added NKSP int array and real array tests for value assignment and |
| 321 |
|
initialization of arrays. |
| 322 |
|
- Added NKSP test cases for built-in functions "round()", "ceil()", |
| 323 |
|
"floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", |
| 324 |
|
"sin()", "cos()", "tan()", "asin()", "acos()", "atan()". |

| 328 |
|
|
| 329 |
|
* GigaStudio/Gigasampler format engine: |
| 330 |
|
- LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true |
| 331 |
|
behaviour for start_level_mid. |
| 332 |
|
- Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start |
| 333 |
|
level (see discussion "GigaStudio LFO compatibility" on mailing list |
| 334 |
|
from 2019-09-26 for details). |
| 335 |
|
- Changed default wave form for all 3 LFOs to sine (instead of triangle; |
| 336 |
|
see discussion "GigaStudio LFO compatibility" on mailing list from |
| 337 |
|
2019-09-26 for details). |
| 338 |
|
- Format extension: Added support for different LFO wave forms (currently |
| 339 |
|
either sine [default], triangle, saw or square). |
| 340 |
|
- Format extension: Added support for LFO phase displacement (0°..360°). |
| 341 |
|
- Format extension: Added support for flipping LFO polarity on LFO 3 |
| 342 |
|
(in the original gig format this was only available for LFO 1 and LFO 2). |
| 343 |
|
- Format extension: Support for additional filter types: |
| 344 |
|
lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole, |
| 345 |
|
bandreject 2-pole. |
| 346 |
|
- Fixd potential crash with polynomial interpolator and max. pitch. |
| 347 |
|
- If minimum cutoff is defined, remap cutoff controller CC values to really |
| 348 |
|
span the entire possible cutoff range (and avoiding a dead controller |
| 349 |
|
zone). |
| 350 |
|
- Implemented support for loading instrument scripts with 'patch' variables |
| 351 |
|
(by patching these script variables with potentially overridden ones by |
| 352 |
|
gig Instrument). |
| 353 |
|
|
| 354 |
|
* SFZ format engine: |
| 355 |
|
- Fixed support for regions with loccN/hiccN conditions on more than one |
| 356 |
|
MIDI controller. |
| 357 |
|
- Fixed internal opcode 'xfin_hivel' falsely being set by user opcode |
| 358 |
|
'xfin_lovel' (patch by Christian Czezatke). |
| 359 |
|
|
| 360 |
|
* Benchmarks: |
| 361 |
|
- Fixed benchmarks/triang.cpp falsely having favoured "int math abs" |
| 362 |
|
algorithm (since result of 2nd run was not accumulated). |
| 363 |
|
- Added benchmark for saw wave (benchmarks/saw.cpp). |
| 364 |
|
- Added benchmark for sine wave (benchmarks/sine.cpp). |
| 365 |
|
- Added benchmark for square wave (benchmarks/square.cpp). |
| 366 |
|
- Increased amount of benchmarks runs by factor 6 to achieve benchmark times |
| 367 |
|
which are large enough on modern systems. |
| 368 |
|
|
| 369 |
|
Version 2.1.1 (27 Jul 2019) |
| 370 |
|
|
| 371 |
|
* Real-time instrument scripts: |
| 372 |
|
- Fixed behavior of built-in NKSP functions change_sustain(), |
| 373 |
|
change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain() |
| 374 |
|
and change_cutoff_release(). |
| 375 |
|
|
| 376 |
|
* general changes: |
| 377 |
|
- Only play release trigger samples on sustain pedal up if this behaviour |
| 378 |
|
was explicitly requested by the instrument (otherwise only on note-off). |
| 379 |
|
- Fixed compiler warnings. |
| 380 |
|
- Fixed compilation error when cross-compiling to Mac. |
| 381 |
|
- FX Sends: Provide more useful error messages on routing problems |
| 382 |
|
(see bug #169). |
| 383 |
|
- LSCP doc: Be more clear describing the two distinct approaches |
| 384 |
|
of using external vs. internal effects (see bug #169). |
| 385 |
|
- "optional" class: Fixed comparison operators. |
| 386 |
|
|
| 387 |
|
* Gigasampler/GigaStudio format engine: |
| 388 |
|
- Format extension: If requested by instrument then don't play release |
| 389 |
|
trigger sample on note-off events. |
| 390 |
|
|
| 391 |
|
* SFZ format engine: |
| 392 |
|
- Fixed memory leak when releasing samples |
| 393 |
|
(fixes bug #307, patch by Jacek Roszkowski) |
| 394 |
|
- Fixed potential crash when a sample is shared by more than one region |
| 395 |
|
(fixes bug #308, patch by Jacek Roszkowski). |
| 396 |
|
- Opcode 'sample': Added support for built-in sample '*silence' |
| 397 |
|
(fixes bug #310, patch by Jacek Roszkowski). |
| 398 |
|
|
| 399 |
|
Version 2.1.0 (25 Nov 2017) |
| 400 |
|
|
| 401 |
|
* SFZ format engine: |
| 402 |
|
- added support for <global>, <master> and #define (patch by Alby M) |
| 403 |
|
- Removed code duplication in SFZ file loading code. |
| 404 |
|
- Added support for sfz extension opcode 'script' which may be used to |
| 405 |
|
load real-time instrument script file (NKSP script language). |
| 406 |
|
- Implemented opcode set_ccN (initial patch by Giovanni Senatore). |
| 407 |
|
- Fixed unintended volume fade-in of voices under certain conditions. |
| 408 |
|
- sfz parser: allow missing space between header and opcode |
| 409 |
|
|
| 410 |
|
* Gigasampler/GigaStudio format engine: |
| 411 |
|
- Fixed clicks and pumping noise with Lowpass Turbo filter on very low |
| 412 |
|
cutoff settings. |
| 413 |
|
- Got rid of resembling an ancient GSt misbehavior which did not pitch at |
| 414 |
|
all if an up-pitch of more than 40 semi tones was requested (I don't |
| 415 |
|
think there is any stock gig sound that requires this behavior to |
| 416 |
|
resemble its original sound). |
| 417 |
|
- Added support for controlling whether the individual EGADSR stages may |
| 418 |
|
be aborted (as LinuxSampler extension to the original GigaStudio 4 |
| 419 |
|
format). |
| 420 |
|
|
| 421 |
|
* general changes: |
| 422 |
|
- fixed printf type errors (mostly in debug messages) |
| 423 |
|
- use unique_ptr instead of auto_ptr when building with C++11 |
| 424 |
|
- Added RTAVLTree class which is a real-time safe ordered multi-map, thus |
| 425 |
|
allowing to sort data efficiently in real-time safe manner. |
| 426 |
|
- RTList class: added methods for moving/inserting elements to arbitrary |
| 427 |
|
position within a list. |
| 428 |
|
- RTList class: added method fromPtr() for creating an Iterator object from |
| 429 |
|
a raw element pointer. |
| 430 |
|
- Attempt to partly fix resetting engine channels vs. resetting engine, an |
| 431 |
|
overall cleanup of the Reset*(), ConnectAudioDevice(), |
| 432 |
|
DisconnectAudioDevice() API methods would still be desirable though, |
| 433 |
|
because the current situation is still inconsistent and error prone. |
| 434 |
|
- Active voices are now internally grouped to "Note" objects, instead of |
| 435 |
|
being directly assigned to a keyboard key. This allows more fine graded |
| 436 |
|
processing of voices, which is i.e. required for certain instrument |
| 437 |
|
script features. |
| 438 |
|
- Fix: Release trigger voices were not spawned on sustain pedal up |
| 439 |
|
(CC #64) events. |
| 440 |
|
- Fix: Release trigger voices can now also distinguish correctly between |
| 441 |
|
note-off and sustain pedal up events. |
| 442 |
|
- All engines: Increased ramp speed of volume smoother and pan smoother |
| 443 |
|
(while slow rate of crossfade smoother is preserved) to allow quick |
| 444 |
|
volume and pan changes by instrument scripts for instance. |
| 445 |
|
- gig/sf2/sfz: Fixed aftertouch channel pressure events being processed |
| 446 |
|
properly and thus were ignored for certain uses. |
| 447 |
|
- Added new C++ API method |
| 448 |
|
VirtualMidiDevice::SendChannelPressureToSampler(). |
| 449 |
|
- windows, 32-bit: fixed potential crashes by making sure the stack in |
| 450 |
|
sub threads is 16-byte aligned |
| 451 |
|
- fixed numerous compiler warnings |
| 452 |
|
- Fixed invalid (note-on) event ID being assigned to new Note objects. |
| 453 |
|
- Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which |
| 454 |
|
fixes potential undefined behavior. |
| 455 |
|
- Fixed Note object leak when triggering notes on keys which did not |
| 456 |
|
have a valid sample mapped (fixes bug #252). |
| 457 |
|
- Fixed compilation errors when compiling with CONFIG_DEVMODE enabled. |
| 458 |
|
- linuxsampler binary fix: option --create-instruments-db ignored |
| 459 |
|
subsequent optional argument due to glibc's implementation oddity |
| 460 |
|
which expects a "=" sign, but no space between them. |
| 461 |
|
|
| 462 |
|
* packaging changes: |
| 463 |
|
- removed unnecessary dependency to libuuid |
| 464 |
|
(originated by libgig's usage of it) |
| 465 |
|
- Automake: set environment variable GCC_COLORS=auto to allow GCC to |
| 466 |
|
auto detect whether it (sh/c)ould output its messages in color. |
| 467 |
|
- Debian: Fixed packaging error about invalid "Source-Version" |
| 468 |
|
substitution variable. |
| 469 |
|
- Debian: Raised Debian compatibility level to Debian 9 "Stretch". |
| 470 |
|
- Debian: Added build dependency to libsqlite3-dev for building |
| 471 |
|
linuxsampler with instruments DB support. |
| 472 |
|
|
| 473 |
|
* Real-time instrument scripts: |
| 474 |
|
- Implemented scheduler for delayed MIDI events and for suspended scripts. |
| 475 |
|
- Built-in script function "wait()": implemented support for function's |
| 476 |
|
"duration-us" argument, thus scripts using this function are now |
| 477 |
|
correctly resumed after the requested amount of microseconds. |
| 478 |
|
- Built-in script function "play_note()": implemented support for |
| 479 |
|
function's "duration-us" argument, thus notes triggered with this |
| 480 |
|
argument are now correctly released after the requested amount of |
| 481 |
|
microseconds. |
| 482 |
|
- Fix: script events were not cleared when engine channel was reset, |
| 483 |
|
potentially causing undefined behavior. |
| 484 |
|
- Fixed crash which happened when trying to reference an undeclared |
| 485 |
|
variable. |
| 486 |
|
- Built-in script function "play_note()": Added support for passing |
| 487 |
|
special value -1 for "duration-us" argument, which will cause the |
| 488 |
|
triggered note to be released once the original note was released. |
| 489 |
|
- Instrument script classes now exported with the liblinuxsampler C++ API. |
| 490 |
|
- Added new API method ScriptVM::syntaxHighlighting() which provides |
| 491 |
|
a convenient syntax highlighting backend for external instrument |
| 492 |
|
script editor applications. |
| 493 |
|
- Added new C++ API class "ScriptVMFactory". |
| 494 |
|
- Extended parser issues to provide not only first line and first |
| 495 |
|
column, but also last line and last column of issue (thus marking |
| 496 |
|
the precise span of the issue within the source code). |
| 497 |
|
- Reload script automatically after being modified by an instrument |
| 498 |
|
editor. |
| 499 |
|
- NKSP language grammar correction: allow empty event handler bodies |
| 500 |
|
like "on note end on". |
| 501 |
|
- Implemented built-in script function "change_vol()". |
| 502 |
|
- Implemented built-in script function "change_tune()". |
| 503 |

| 504 |
|
- Implemented built-in script function "change_cutoff()". |
| 505 |
|
- Implemented built-in script function "change_reso()". |
| 506 |
|
- Implemented built-in script function "event_status()". |
| 507 |
|
- Added built-in script constants "$EVENT_STATUS_INACTIVE" and |
| 508 |
|
"$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for |
| 509 |
|
"event_status()" function. |
| 510 |
|
- NKSP language: Added support for bitwise operators ".or.", ".and." |
| 511 |
|
and ".not.". |
| 512 |
|
- NKSP language scanner: Fixed IDs matching to require at least one |
| 513 |
|
character (i.e. when matching function names or variable names). |
| 514 |
|
- NKSP language scanner: disabled unusued rules. |
| 515 |
|
- Fixed behavior of play_note() and note_off() functions which must |
| 516 |
|
be distinguished engine internally from "real" MIDI note on/off |
| 517 |
|
events in order to avoid misbehaviors like hanging notes. |
| 518 |
|
- Implemented built-in script variable "$KSP_TIMER". |
| 519 |
|
- Implemented built-in script variable "$NKSP_REAL_TIMER". |
| 520 |
|
- Implemented built-in script variable "$NKSP_PERF_TIMER". |
| 521 |
|
- Implemented built-in script variable "$ENGINE_UPTIME". |
| 522 |
|
- Implemented built-in script function "inc()". |
| 523 |
|
- Implemented built-in script function "dec()". |
| 524 |
|
- NKSP language fix: division expressions were evaluated too often. |
| 525 |
|
- NKSP language fix: string concatenation operator was right |
| 526 |
|
associative instead of left (to right). |
| 527 |
|
- NKSP language correction: allow empty statements in entire language |
| 528 |
|
(i.e. "if end if"). |
| 529 |
|
- Implemented built-in script function "stop_wait()". |
| 530 |
|
- Implemented built-in script variable "$NI_CALLBACK_ID". |
| 531 |
|
- Implemented built-in script variable "$NI_CALLBACK_TYPE". |
| 532 |
|
- Implemented built-in script variable "$NKSP_IGNORE_WAIT". |
| 533 |
|
- Added support for read-only built-in variables (respectively |
| 534 |
|
handled by the script parser). |
| 535 |
|
- Added built-in script constant "$NI_CB_TYPE_INIT". |
| 536 |
|
- Added built-in script constant "$NI_CB_TYPE_NOTE". |
| 537 |
|
- Added built-in script constant "$NI_CB_TYPE_RELEASE". |
| 538 |
|
- Added built-in script constant "$NI_CB_TYPE_CONTROLLER". |
| 539 |
|
- NKSP Language: Added support for user defined script functions. |
| 540 |
|
- Implemented built-in script function "change_attack()". |
| 541 |
|
- Implemented built-in script function "change_decay()". |
| 542 |
|
- Implemented built-in script function "change_release()". |
| 543 |
|
- Fixed all change_*() built-in script functions to apply their |
| 544 |
|
synthesis parameter changes immediately in case the respective note |
| 545 |
|
was triggered at the same time, instead of scheduling the parameter |
| 546 |
|
change, especially because it would cause some parameter types's |
| 547 |
|
changes either to be ramped (i.e. change_vol()) or other types even |
| 548 |
|
to have not effect at all (i.e. change_attack()). |
| 549 |
|
- Implemented built-in script function "sh_left()". |
| 550 |
|
- Implemented built-in script function "sh_right()". |
| 551 |
|
- Implemented built-in script function "min()". |
| 552 |
|
- Implemented built-in script function "max()". |
| 553 |
|
- NKSP Fix: "init" event handler was not always executed when a script |
| 554 |
|
was loaded. |
| 555 |
|
- NKSP built-in wait() script function: abort script execution if |
| 556 |
|
a negative or zero wait time was passed as argument (since this is |
| 557 |
|
a common indication of a bug either of the script or even of the |
| 558 |
|
engine, which could lead to RT instability or even worse). |
| 559 |
|
- ScriptVM: Implemented automatic suspension of RT safety |
| 560 |
|
threatening scripts. |
| 561 |
|
- Provide more user friendly error messages on syntax errors. |
| 562 |
|
- Fixed NKSP parser warning "Not a statement" when assigning an |
| 563 |
|
initializer list to an array variable. |
| 564 |
|
- Implemented built-in script array variable "%ALL_EVENTS". |
| 565 |
|
- Implemented built-in script function "in_range()". |
| 566 |
|
- Implemented built-in script function "change_amp_lfo_depth()". |
| 567 |
|
- Implemented built-in script function "change_amp_lfo_freq()". |
| 568 |
|
- Implemented built-in script function "change_pitch_lfo_depth()". |
| 569 |
|
- Implemented built-in script function "change_pitch_lfo_freq()". |
| 570 |
|
- Implemented built-in script function "change_vol_time()". |
| 571 |
|
- Implemented built-in script function "change_tune_time()". |
| 572 |
|
- Implemented built-in script function "fade_in()". |
| 573 |
|
- Implemented built-in script function "fade_out()". |
| 574 |
|
- Fixed acceptance of wrong data type of parameters passed to built-in |
| 575 |
|
script functions "change_vol()", "change_tune()", "change_pan()", |
| 576 |
|
"change_cutoff()", "change_reso()", "change_attack()", "change_decay()", |
| 577 |
|
"change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()", |
| 578 |
|
"change_pitch_lfo_depth()" and "change_pitch_lfo_freq()". |
| 579 |
|
- Added built-in script function "get_event_par()" and implemented some |
| 580 |
|
of its possible parameter selections. |
| 581 |
|
- Added built-in script function "set_event_par()" and implemented some |
| 582 |
|
of its possible parameter selections. |
| 583 |
|
- Fixed a bunch of scheduler time related bugs. |
| 584 |
|
- Fixed polyphonic variables not being reset to zero after usage. |
| 585 |
|
- Built-in "ignore_event()" function: argument is now optional, like with |
| 586 |
|
built-in function "ignore_controller()". |
| 587 |
|
- Implemented built-in script function "change_velo()". |
| 588 |
|
- Implemented built-in script function "change_note()". |
| 589 |
|
- Adjusted behavior of "change_vol()" and "change_tune()" to a more |
| 590 |
|
intuitive behavior if used in combination with "change_vol_time()" or |
| 591 |
|
"change_tune_time()" respectively: now tuning/volume changes are only |
| 592 |
|
assigned (without delay) immediately to a new note if the respective |
| 593 |
|
timing function has not been called before, otherwise the volume/tuning |
| 594 |
|
changes are automatically faded (before, only the event's time stamp was |
| 595 |
|
relevant). |
| 596 |
|
- Implemented built-in script function "array_equal()". |
| 597 |
|
- Implemented built-in script function "search()". |
| 598 |
|
- Implemented built-in script function "sort()". |
| 599 |
|
- NKSP Fix: Never suspend "init" event handlers. |
| 600 |
|
- Implemented built-in script function "same_region()" (currently only |
| 601 |
|
available for gig format engine). |
| 602 |
|
- Added built-in script constant "$NKSP_LINEAR". |
| 603 |
|
- Added built-in script constant "$NKSP_EASE_IN_EASE_OUT". |
| 604 |
|
- Implemented built-in script function "change_vol_curve()". |
| 605 |
|
- Implemented built-in script function "change_tune_curve()". |
| 606 |
|
- built-in "play_note()" function now supports a sample playback start |
| 607 |
|
offset with argument 3, where special value -1 means to use the regular |
| 608 |
|
sample offset as defined by the instrument file. |
| 609 |
|
- Built-in array variable %KEY_DOWN[] is now a read-only variable. |
| 610 |
|
- Built-in variable $EVENT_NOTE is now a read-only variable. |
| 611 |
|
- Built-in variable $EVENT_VELOCITY is now a read-only variable. |
| 612 |
|
- built-in "play_note()" function now accepts -2 for its fourth argument |
| 613 |
|
(note duration) which means the life time of the note shall be sticked |
| 614 |
|
to the requested note number of argument 1. |
| 615 |
|
- Fix: built-in "play_note()" function now returns 0 as result value if |
| 616 |
|
-1 was passed for its fourth argument (note duration) and the respective |
| 617 |
|
parent note is already gone. |
| 618 |
|
- Implemented built-in script function "change_play_pos()". |
| 619 |
|
- NKSP language: Added support for user declared const array variables. |
| 620 |
|
- NKSP language: Raise parser warning if array variable is accessed with |
| 621 |
|
an index that exceeds the array's size. |
| 622 |
|
- NKSP language fix: Unknown characters were not handled correctly. |
| 623 |
|
- NKSP language: Added support for "synchronized .. end synchronized" |
| 624 |
|
code blocks. |
| 625 |
|
- Implemented built-in script function "abort()" which allows to abort |
| 626 |
|
another script handler by passing its callback ID. |
| 627 |
|
- Fixed potential memory access bug and potential undefined behavior of |
| 628 |
|
"init" event handlers. |
| 629 |
|
- Print a time stamp along to each call of built-in function "message()". |
| 630 |
|
- ScriptVM API: Added VMParserContext::preprocessorComments() which allows |
| 631 |
|
to retrieve all code blocks filtered out by the preprocessor. |
| 632 |
|
- Added built-in script function "fork()". |
| 633 |
|
- Added built-in array variable %NKSP_CALLBACK_CHILD_ID[]. |
| 634 |
|
- Added built-in variable $NKSP_CALLBACK_PARENT_ID. |
| 635 |
|
- Fixed potential crash when accessing dynamic built-in array variables. |
| 636 |
|
- Added built-in script function "callback_status()". |
| 637 |
|
- Added built-in constant $CALLBACK_STATUS_TERMINATED. |
| 638 |
|
- Added built-in constant $CALLBACK_STATUS_QUEUE. |
| 639 |
|
- Added built-in constant $CALLBACK_STATUS_RUNNING. |
| 640 |
|
- Removed max. value limitation of built-in functions "change_attack()", |
| 641 |
|
"change_decay()" and "change_release()" to i.e. allow passing 2000000 |
| 642 |
|
for doubling the respective time. |
| 643 |
|
- NKSP script editor syntax highlighting API: Fixed app termination due |
| 644 |
|
to a lexer start condition stack underrun. |
| 645 |
|
- NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and |
| 646 |
|
USE_CODE_IF_NOT() preprocessor statements. |
| 647 |
|
- NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which |
| 648 |
|
can be set to disable all subsequent built-in "message()" function calls |
| 649 |
|
on preprocessor level. |
| 650 |
|
- Implemented built-in script function "change_sustain()". |
| 651 |
|
- NKSP script editor syntax highlighting API: catch all fatal lexer errors, |
| 652 |
|
to avoid the editor app to crash on ill-formed text input. |
| 653 |
|
- Added built-in script function "change_pan_time()". |
| 654 |

* Instruments DB: |
| 663 |
|
- Fixed memory access bug of general DB access code which lead to |
| 664 |
|
undefined behavior. |
| 665 |
|
- Cleanup of instruments DB file creation and opening code. |
| 666 |
|
- The instrument DB path of linuxsampler's --create-instruments-db argument |
| 667 |
|
is now optional, if it is missing, then a default location is used. |
| 668 |
|
- Added support for scanning SFZ (.sfz) files. |
