(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 |

and their potential metric prefix token. |
| 82 |
|
- NKSP language: Added support for NKSP real number literals and |
| 83 |
|
arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0"). |
| 84 |
|
- NKSP language: Added support for NKSP real number (floating point) script |
| 85 |
|
variables (declare ~foo). |
| 86 |
|
- NKSP language: Added support for NKSP real number (floating point) array |
| 87 |
|
script variables (declare ?foo[]). |
| 88 |
|
- Built-in script function "message()" accepts now real number argument as |
| 89 |
|
well. |
| 90 |
|
- Added built-in script function "real_to_int()" and its short hand form |
| 91 |
|
"int()" for casting from real number to integer in NKSP scripts. |
| 92 |
|
- Added built-in script function "int_to_real()" and its short hand form |
| 93 |
|
"real()" for casting from integer to real number in NKSP scripts. |
| 94 |
|
- Allow built-in exit() function to potentially accept real number type |
| 95 |
|
argument as well. |
| 96 |
|
- Built-in script functions may have a different return type depending on |
| 97 |
|
the arguments passed to the function. |
| 98 |
|
- Built-in script function "abs()" optionally accepts and returns real |
| 99 |
|
number. |
| 100 |
|
- Built-in script functions "min()" and "max()" optionally accept real |
| 101 |
|
number arguments and return real number as result in that case. |
| 102 |
|
- NKSP VM API: Allow units and 'final'ness to be returned as result from |
| 103 |
|
built-in functions (added methods VMFunction::returnUnitType() and |
| 104 |
|
VMFunction::returnsFinal() for that purpose which must be implemented by |
| 105 |
|
built-in function implementations). |
| 106 |
|
- NKSP language: Allow metric unit prefixes of numeric scalar and array |
| 107 |
|
variables to be changed freely at runtime (unlike unit types like Hz etc. |
| 108 |
|
which are still sticky, parse-time features of variables which cannot be |
| 109 |
|
changed at runtime for the intentional sake of determinism). |
| 110 |
|
- NKSP language: 'final' values are prohibited for array variables for now |
| 111 |
|
(attempt causes a parsers error). |
| 112 |
|
- NKSP language: expressions with unit types (e.g. Hz) are prohibited for |
| 113 |
|
conditions of runtime control structures like if(), while(), select() |
| 114 |
|
(attempt causes a parser error). |
| 115 |
|
- NKSP VM API: Allow built-in functions to perform their own, individual |
| 116 |
|
parse time checks of arguments going to be passed to the function at |
| 117 |
|
runtime (added method VMFunction::checkArgs() for that purpose). |
| 118 |
|
- NKSP language: raise parser warning if only one operand of binary |
| 119 |
|
operators (like logical 'or' comparison) contain a 'final' value (because |
| 120 |
|
it would always yield in a 'final' result in such cases). |
| 121 |
|
- NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with |
| 122 |
|
different metric unit prefixes, which will behave as expected (e.g. |
| 123 |
|
result of expression '1000us < 2ms' is true). |
| 124 |
|
- NKSP language: Allow adding values with different metric unit prefixes |
| 125 |
|
(e.g. result of expression '100Hz + 5kHz' is '5100Hz'). |
| 126 |
|
- NKSP language: Allow subtracting values with different metric unit |
| 127 |
|
prefixes (e.g. result of expression '1ms - 20us' is '980us'). |
| 128 |
|
- NKSP language: Allow multiplying with any metric unit prefixes |
| 129 |
|
(e.g. result of expression '2k * 3ms' is '6s'), however multiplications |
| 130 |
|
with unit types on both sides (e.g. '2s * 2s') is still prohibited since |
| 131 |
|
we don't have any considerable practical use for a term like '4s^2' |
| 132 |
|
(hence any attempt multiplying two unit types still causes parser error). |
| 133 |
|
- NKSP language: Allow dividing by any metric unit prefixes and allow |
| 134 |
|
division of same unit type on both sides (e.g. expression '8kHz / 1000Hz' |
| 135 |
|
yields in unit free result '8'). So this is now a way to cast units away |
| 136 |
|
e.g. for passing the result to other expressions, certain function calls |
| 137 |
|
or variables which are not accepting any units (or that specific unit). |
| 138 |
|
- NKSP language: integer arrays and real number arrays can now be converted |
| 139 |
|
to strings (e.g. for dumping their content with message() calls for |
| 140 |
|
script debugging purposes). |
| 141 |
|
- NKSP language: expressions and variables with units are now correctly |
| 142 |
|
casted to strings (e.g. with message() calls). |
| 143 |
|
- NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or |
| 144 |
|
unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected |
| 145 |
|
floating point tolerances into account. |
| 146 |
|
- NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and |
| 147 |
|
VMScalarNumberExpr::evalCastReal(). |
| 148 |
|
- NKSP VM API: Added base class 'VMNumberArrayExpr' for classes |
| 149 |
|
'VMIntArrayExpr' and 'VMRealArrayExpr'. |
| 150 |
|
- NKSP VM API: replaced all unitPrefix() (parse time) methods by |
| 151 |
|
unitFactor() (runtime) methods. |
| 152 |
|
- Built-in function "exit()" supports now returning units and 'final'ness |
| 153 |
|
for test cases. |
| 154 |
|
- The following built-in functions support now units as well: "abs()", |
| 155 |
|
"random()", "inc()", "dec()", "in_range()", "min()", "max()", |
| 156 |
|
"real_to_int()", "int()", "int_to_real()" and "real()". |
| 157 |
|
- Built-in functions "array_equal()", "search()" and "sort()" support now |
| 158 |
|
real number arrays (correctly) as well. |
| 159 |
|
- Added individual parse time checks of arguments to be passed to built-in |
| 160 |
|
functions "random()", "inc()", "dec()", "in_range()", "min()", "max()", |
| 161 |
|
"array_equal()" and "search()" specific for their individual purposes. |
| 162 |
|
- NKSP VM refactoring: Renamed all methods, functions and classes matching |
| 163 |
|
pattern *ScalarNumber* to simply *Number* (that is i.e. classes |
| 164 |
|
VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr, |
| 165 |
|
ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp -> |
| 166 |
|
NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction, |
| 167 |
|
method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function |
| 168 |
|
isScalarNumber() -> isNumber()). |
| 169 |
|
- NKSP VM API: Added 4 overridden methods to class VMNumberExpr: |
| 170 |
|
evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t), |
| 171 |
|
evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t) |
| 172 |
|
as convenient methods for automatically converting values to expected |
| 173 |
|
metric value basis. |
| 174 |
|
- Built-in function "wait()" accepts now both integers and real numbers as |
| 175 |
|
argument. |
| 176 |
|
- NKSP VM API cleanup: Get rid of legacy method |
| 177 |
|
VMFunction::argType(vmint iArg) which was already superseded by its new |
| 178 |
|
replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type). |
| 179 |
|
- NKSP parser: if wrong argument type was passed to a built-in function and |
| 180 |
|
that built-in function accepts more than one data type for the argument, |
| 181 |
|
then show all supported data types as parser error message. |
| 182 |
|
- Built-in function "play_note()" accepts now real numbers and seconds as |
| 183 |
|
unit type as well for its 3rd and 4th function arguments. |
| 184 |
|
- The following built-in functions accept now real numbers as well for their |
| 185 |
|
2nd function argument: "change_vol()", "change_tune()", "change_cutoff()", |
| 186 |
|
"change_attack()", "change_decay()", "change_release()", |
| 187 |
|
"change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()", |
| 188 |
|
"change_cutoff_sustain()", "change_cutoff_release()", |
| 189 |
|
"change_amp_lfo_freq()", "change_cutoff_lfo_freq()", |
| 190 |
|
"change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()", |
| 191 |
|
"change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()". |
| 192 |
|
- Fixed built-in function "change_play_pos()" not having accepted metric |
| 193 |
|
prefixes at all. |
| 194 |
|
- Fixed the following built-in functions having misinterpreted values given |
| 195 |
|
with unit type (for their 2nd argument) as if they were relative values |
| 196 |
|
(that is as if they were passed without a unit type): "change_attack()", |
| 197 |
|
"change_decay()", "change_release()", "change_cutoff_attack()", |
| 198 |
|
"change_cutoff_decay()", "change_cutoff_release()". |
| 199 |
|
- Fixed the following built-in functions having applied completely wrong |
| 200 |
|
'final' values: "change_sustain()", "change_cutoff_sustain()" (since the |
| 201 |
|
respective EGs being their modulation sink assume uint data type with |
| 202 |
|
value range 0..1000 instead of 0.0..1.0. |
| 203 |
|
- Added individual parse-time checks of function arguments for the following |
| 204 |
|
built-in functions: "play_note()", "note_off()", "set_event_mark()", |
| 205 |
|
"delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()", |
| 206 |
|
"change_decay()", "change_release()", "change_cutoff_attack()", |
| 207 |
|
"change_cutoff_decay()", "change_cutoff_release()", |
| 208 |
|
"change_amp_lfo_freq()", "change_cutoff_lfo_freq()", |
| 209 |
|
"change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and |
| 210 |
|
"change_pan_time()". |
| 211 |
|
- Don't abort function call if unit type was used and at the same time |
| 212 |
|
'final' operator was omitted for the primary value argument of the |
| 213 |
|
following built-in functions: "change_cutoff()", "change_attack()", |
| 214 |
|
"change_decay()", "change_release()", "change_cutoff_attack()", |
| 215 |
|
"change_cutoff_decay()", "change_cutoff_release()", |
| 216 |
|
"change_amp_lfo_freq()", "change_cutoff_lfo_freq()", |
| 217 |
|
"change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()", |
| 218 |
|
"change_pan_time()", instead imply 'final'ness at runtime and raise an |
| 219 |
|
appropriate parser warning at parse time. |
| 220 |
|
- Added built-in real number functions "round()", "ceil()", "floor()", |
| 221 |
|
"sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()", |
| 222 |
|
"cos()", "tan()", "asin()", "acos()", "atan()". |
| 223 |
|
- Added built-in script real number constant "~NI_MATH_PI". |
| 224 |
|
- Added built-in script real number constant "~NI_MATH_E". |
| 225 |
|
- NKSP language: Allow unary '+' operator. |
| 226 |
|
- Added built-in script functions "msb()" and "lsb()". |
| 227 |
|
- NKSP language: Added support for RPN event handler |
| 228 |
|
("on rpn ... end on" in instrument scripts). |
| 229 |
|
- NKSP language: Added support for NRPN event handler |
| 230 |
|
("on nrpn ... end on" in instrument scripts). |
| 231 |
|
- Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which |
| 232 |
|
may be read from the new RPN/NRPN script handlers to get the (N)RPN |
| 233 |
|
parameter that had been changed and its new value. |
| 234 |
|
- Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN" |
| 235 |
|
which are identifying the new (N)RPN handlers as such at script runtime. |
| 236 |
|
- Implemented built-in script function "set_rpn()". |
| 237 |
|
- Implemented built-in script function "set_nrpn()". |
| 238 |
|
- Fix: built-in functions returning an array type were broken and caused a |
| 239 |
|
crash when the built-in function's (supposed to be array) result value was |
| 240 |
|
used by the script VM. |
| 241 |
|
- Removed upper value constraint for 2nd argument of built-in functions |
| 242 |
|
"change_amp_lfo_freq()", "change_cutoff_lfo_freq()", |
| 243 |
|
"change_pitch_lfo_freq()","change_reso()", "change_cutoff()", |
| 244 |
|
"change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and |
| 245 |
|
"change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double |
| 246 |
|
the LFO frequency / resonance / cutoff frequency. |
| 247 |
|
- Reduced code involved for parsing NKSP variable declarations by using 2 |
| 248 |
|
generalized grammar rules with optional components (i.e. optional value |
| 249 |
|
assignment and optional variable qualifiers) instead of previous linear |
| 250 |
|
combinations of grammar rules, which also fixes some edge case. |
| 251 |
|
- NKSP language parser: track code block locations also by a) raw byte |
| 252 |
|
position in NKSP source code string and b) length of that code block in |
| 253 |
|
bytes (along to the already existing code block tracking by line/column); |
| 254 |
|
and added appropriate new members to public C++ API classes like |
| 255 |
|
'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock. |
| 256 |

int_to_real(), real(), real_to_int() and int(), as well as for the |
| 269 |
|
plus, minus and negate language operators. |
| 270 |
|
- Added massive amount of NKSP test cases for standard measuring units and |
| 271 |
|

|
- Added NKSP test cases for (floating point tolerance aware) real number |
| 273 |

| 283 |
|
* GigaStudio/Gigasampler format engine: |
| 284 |
|
- LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true |
| 285 |
|
behaviour for start_level_mid. |
| 286 |
|
- Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start |
| 287 |
|
level (see discussion "GigaStudio LFO compatibility" on mailing list |
| 288 |
|
from 2019-09-26 for details). |
| 289 |
|
- Changed default wave form for all 3 LFOs to sine (instead of triangle; |
| 290 |
|
see discussion "GigaStudio LFO compatibility" on mailing list from |
| 291 |
|
2019-09-26 for details). |
| 292 |
|
- Format extension: Added support for different LFO wave forms (currently |
| 293 |
|
either sine [default], triangle, saw or square). |
| 294 |
|
- Format extension: Added support for LFO phase displacement (0°..360°). |
| 295 |
|
- Format extension: Added support for flipping LFO polarity on LFO 3 |
| 296 |
|
(in the original gig format this was only available for LFO 1 and LFO 2). |
| 297 |
|
- Format extension: Support for additional filter types: |
| 298 |
|
lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole, |
| 299 |
|
bandreject 2-pole. |
| 300 |
|
- Fixd potential crash with polynomial interpolator and max. pitch. |
| 301 |
|
- If minimum cutoff is defined, remap cutoff controller CC values to really |
| 302 |
|
span the entire possible cutoff range (and avoiding a dead controller |
| 303 |
|
zone). |
| 304 |
|
|
| 305 |
|
* SFZ format engine: |
| 306 |
|
- Fixed support for regions with loccN/hiccN conditions on more than one |
| 307 |
|
MIDI controller. |
| 308 |
|
|
| 309 |
|
* Benchmarks: |
| 310 |
|
- Fixed benchmarks/triang.cpp falsely having favoured "int math abs" |
| 311 |
|
algorithm (since result of 2nd run was not accumulated). |
| 312 |
|
- Added benchmark for saw wave (benchmarks/saw.cpp). |
| 313 |
|
- Added benchmark for sine wave (benchmarks/sine.cpp). |
| 314 |
|
- Added benchmark for square wave (benchmarks/square.cpp). |
| 315 |
|
- Increased amount of benchmarks runs by factor 6 to achieve benchmark times |
