Revision 3588 - Directory Listing
Modified Sun Sep 1 16:06:48 2019 UTC (4 years, 7 months ago) by schoenebeck

NKSP: Built-in instrument functions fixes & hardening:

* Fixed the following built-in functions having misinterpreted values given
  with unit type (for their 2nd argument) as if they were relative values
  (that is as if they were passed without a unit type): "change_attack()",
  "change_decay()", "change_release()", "change_cutoff_attack()",
  "change_cutoff_decay()", "change_cutoff_release()".

* Fixed the following built-in functions having applied completely wrong
  'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
  respective EGs being their modulation sink assume uint data type with
  value range 0..1000 instead of 0.0..1.0.

* Added individual parse-time checks of function arguments for the following
  built-in functions: "play_note()", "note_off()", "set_event_mark()",
  "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
  "change_decay()", "change_release()", "change_cutoff_attack()",
  "change_cutoff_decay()", "change_cutoff_release()",
  "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
  "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
  "change_pan_time()".

* Don't abort function call if unit type was used and at the same time
  'final' operator was omitted for the primary value argument of the
  following built-in functions: "change_cutoff()", "change_attack()",
  "change_decay()", "change_release()", "change_cutoff_attack()",
  "change_cutoff_decay()", "change_cutoff_release()",
  "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
  "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
  "change_pan_time()", instead imply 'final'ness at runtime and raise an
  appropriate parser warning at parse time.

* Bumped version (2.1.1.svn13).

---

Revision 3585 - Directory Listing
Modified Fri Aug 30 17:51:24 2019 UTC (4 years, 7 months ago) by schoenebeck

NKSP: Cleanup regarding multiple data types for built-in function args.

* NKSP VM API cleanup: Get rid of legacy method
  VMFunction::argType(vmint iArg) which was already superseded by its new
  replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).

* NKSP parser: if wrong argument type was passed to a built-in function and
  that built-in function accepts more than one data type for the argument,
  then show all supported data types as parser error message.

* Bumped version (2.1.1.svn10).

---

Revision 3581 - Directory Listing
Modified Fri Aug 30 11:40:25 2019 UTC (4 years, 7 months ago) by schoenebeck

NKSP: Allow more wider support of standard measuring units & 'final'ness.

* Raised compiler requirement to be C++14 compliant (due to severe
  restrictions regarding C-style aggregate initializer lists in C++11
  which are now massively used throughout the code base).

* NKSP VM API: Allow units and 'final'ness to be returned as result from
  built-in functions (added methods VMFunction::returnUnitType() and
  VMFunction::returnsFinal() for that purpose which must be implemented by
  built-in function implementations).

* NKSP language: Allow metric unit prefixes of numeric scalar and array
  variables to be changed freely at runtime (unlike unit types like Hz etc.
  which are still sticky parse-time features of variables which cannot be
  changed at runtime for the intentional sake of determinism).

* NKSP language: 'final' values are prohibited for array variables for now
  (attempt causes a parsers error).

* NKSP language: expressions with unit types (e.g. Hz) are prohibited for
  conditions of runtime control structures like if(), while(), select()
  (attempt causes a parser error).

* NKSP VM API: Allow built-in functions to perform their own, individual
  parse time checks of arguments going to be passed to the function at
  runtime (added method VMFunction::checkArgs() for that purpose).

* NKSP language: raise parser warning if only one operand of binary
  operators (like logical 'or' comparison) contain a 'final' value (because
  it would always yield in a 'final' result in such cases).

* NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
  different metric unit prefixes, which will behave as expected (e.g.
  result of expression '1000us < 2ms' is true).

* NKSP language: Allow adding values with different metric unit prefixes
  (e.g. result of expression '100Hz + 5kHz' is '5100Hz').

* NKSP language: Allow subtracting values with different metric unit
  prefixes (e.g. result of expression '1ms - 20us' is '980us').

* NKSP language: Allow multiplying with any metric unit prefixes
  (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
  with unit types on both sides (e.g. '2s * 2s') is still prohibited since
  we don't have any considerable practical use for a term like '4s^2'
  (hence any attempt multiplying two unit types still causes parser error).

* NKSP language: Allow dividing by any metric unit prefixes and allow
  division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
  yields in unit free result '8'). So this is now a way to cast units away
  e.g. for passing the result to other expressions, certain function calls
  or variables which are not accepting any units (or that specific unit).

* NKSP language: integer arrays and real number arrays can now be converted
  to strings (e.g. for dumping their content with message() calls for
  script debugging purposes).

* NKSP language: expressions and variables with units are now correctly
  casted to strings (e.g. with message() calls).

* NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
  unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
  floating point tolerances into account.

* NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
  VMScalarNumberExpr::evalCastReal().

* NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
  'VMIntArrayExpr' and 'VMRealArrayExpr'.

* NKSP VM API: replaced all unitPrefix() (parse time) methods by
  unitFactor() (runtime) methods.

* Built-in function "exit()" supports now returning units and 'final'ness
  exclusively for test cases.

* The following built-in functions support now units as well: "abs()",
  "random()", "inc()", "dec()", "in_range()", "min()", "max()",
  "real_to_int()", "int()", "int_to_real()" and "real()".

* Built-in functions "array_equal()", "search()" and "sort()" support now
  real number arrays (correctly) as well.

* Added individual parse time checks of arguments to be passed to built-in
  functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
  "array_equal()" and "search()" specific for their individual purposes.

* Test cases: Added massive amount of NKSP test cases for standard
  measuring units and 'final' operator usage cases.

* Test cases: Added NKSP test cases for (floating point tolerance aware)
  real number equalness / unequalness comparison.

* Bumped version (2.1.1.svn8).

Revision 3561 - Directory Listing
Modified Fri Aug 23 11:44:00 2019 UTC (4 years, 8 months ago) by schoenebeck

NKSP: Added standard units support for numbers and final "!" operator:

* NKSP strictness: Variable names, function names and preprocessor condition
  names must start with a regular character (a-z or A-Z); starting them with
  a digit or underscore is no longer allowed.

* NKSP parser fix: equal comparison operator "=" and not equal comparison
  operator "#" must only accept integer operands.

* NKSP language: Implemented support for standard units like Hertz, seconds,
  Bel including support for metric unit prefixes; so one can now e.g.
  conveniently use numbers in scripts like "5us" meaning "5 microseconds",
  or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
  "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).

* NKSP language: Introduced "final" operator "!" which is specifically
  intended for synthesis parameter values to denote that the synthesis
  parameter value is intended to be the "final" value for that synthesis
  parameter that should explicitly be used by the engine and thus causing
  the sampler engine to ignore all other modulation sources for the same
  synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
  variable or formula with this new "!" operator the expression is marked as
  being "final".

* Bumped version (2.1.1.svn4).

Revision 3557 - Directory Listing
Modified Sun Aug 18 00:06:04 2019 UTC (4 years, 8 months ago) by schoenebeck

* NKSP: Introducing 64 bit support for NKSP integer scripts
  variables (declare $foo).
* Require C++11 compiler support.
* Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
  for checking in configure for C++11 support (as mandatory
  requirement) and automatically adds compiler argument if required
  (e.g. -std=C++11).
* Bumped version (2.1.1.svn3).

Modified Tue Apr 19 14:07:53 2016 UTC (8 years ago) by schoenebeck

* All engines: Active voices are now internally grouped to "Note" objects,
  instead of being directly assigned to a keyboard key. This allows more
  fine graded processing of voices, which is i.e. required for certain
  instrument script features.
* Built-in script function "play_note()": Added support for passing

Revision 2871 - Directory Listing
Modified Sun Apr 10 18:22:23 2016 UTC (8 years ago) by schoenebeck

* All engines: Implemented scheduler for delayed MIDI events and for
  suspended real-time instrument scripts.
* Real-Time instrument scripts: Implemented support for built-in "wait()"
  function's "duration-us" argument, thus scripts using this function are
  now correctly resumed after the requested amount of microseconds.
* Real-Time instrument scripts: Implemented support for built-in
  "play_note()" function's "duration-us" argument, thus notes triggered
  with this argument are now correctly released after the requested amount
  of microseconds.
* Real-Time instrument scripts: Fixed crash which happened when trying to
  reference an undeclared script variable.
* Real-Time instrument scripts: Script events were not cleared when
  engine channel was reset, potentially causing undefined behavior.
* All engines: Attempt to partly fix resetting engine channels vs.
  resetting engine, an overall cleanup of the Reset*(),
  ConnectAudioDevice(), DisconnectAudioDevice() API methods would still be
  desirable though, because the current situation is still inconsistent
  and error prone.

Revision 1012 - Directory Listing
Modified Sun Jan 7 15:52:36 2007 UTC (17 years, 3 months ago) by capela

* Fixed a memory leak due to EngineFactory::Destroy() not doing it
as an actual destructor and just removing the engine instance from
factory stock and all instances allocated via EngineFactory::Create()
never got delete'd and thus their destructors never called. This bug
was evident while having many mapped instruments and querying the
instrument status via GET MIDI_INSTRUMENT INFO command, eating up
system memory very quickly and never let it go.

  velocity. The softer velocity, the longer release.
* fine tuning of the envelope curves. Decay1 and release now have two
  parts, first linear and then exponential at the end.

Revision 123 - Directory Listing
Modified Mon Jun 14 19:33:16 2004 UTC (19 years, 10 months ago) by schoenebeck

* src/common: added template class 'optional<>' which can be used e.g. as
  return type whenever a value might be returned, but don't has to; this
  template class pretty much acts like a pointer of the given type, but is
  much more safer than a simple pointer
* src/audiodriver: added static class AudioDeviceFactory to create audio
  devices at runtime by using a string and to obtain driver informations
  of drivers at runtime, driver classes should simply use the macro
  REGISTER_AUDIO_OUTPUT_DRIVER(DriverName,DriverClass) in their cpp file
  to register the driver to LinuxSampler (no changes needed anymore in the
  LS code to add a new audio output driver)
* src/drivers: added classes to dynamically manage driver parameters; there
  are two different kinds of parameters: parameters which are need to
  create a new device (DeviceCreationParameterX) used to e.g. create an
  audio output device or a MIDI input device and parameters which are only
  available at runtime, means when a device is already created
  (DeviceRuntimeParameterX) which will be e.g. used as audio channel
  parameters and MIDI port parameters
* src/linuxsampler.cpp: all registered audio output drivers will be shown
  on the console on startup
* src/network: implemented configuration of audio output devices via LSCP

  (see src/testcases): already added a couple of tests for the Thread and
  Mutex classes, you have to explicitly compile the unit tests by running
  'make testcases' (you need to have cppunit installed though) and then you
  can run the console version of the test runner by calling
  'src/testcases/linuxsamplertest'
* src/Sampler.h: added API documentation
