Moving empty destructors out of the .cpp files and into headers
allows them to be devirtualized in certain cases.
(When the compiler can't "see" a function in a header, it must largely
assume it's some black box that the linker will resolve.)
While we're at it, use C++11's `= default` to define empty virtual
desturctors for us.
For some classes (e.g., Piano), nothing is derived from it, so we can
mark the class as final and remove any explicit virtual dtor.
There are many other places where this can be done, but this is a large
enough patch as-is.
* First Preview of the X-Pressive Plugin
(exprtk.hpp is not included, get it from my exprtk fork in the branch
internal_data_functions)
available keys:
f- note's frequency. available only in the output expressions
t- time in seconds. in the Waves (W1,W2,W3) it's in the range [0,1)
key- the note's keyboard key. available only in the output expressions.
v- the note's velocity (divided by 255.0 so it is in the range [0,1]).
available only in the output expressions.
rel- gives 0 while the key is holded, and 1 after the key release.
available only in the output expressions.
A1,A2,A3- general purpose knobs (you can control them with the
automations). available only in the output expressions.
W1,W2,W3- precalculated wave forms. can be also load from file. you can
use them only in the output expressions
available functions:
cent(x)- gives pow(2,x/1200)
rand()- random number generator. in range [-1,1). each call gives other
value.
randv(i)- random vector (with pseudo infinite integer cells). the values
are in range [-1,1). it's stays consistent only across the note
playback. so each note playback will get other vector (even on the same
key).
sinew- sine wave with period of 1.
saww- saw wave with period of 1.
squarew- square wave with period of 1.
trianglew- triangle wave with period of 1.
expw- exponent wave with period of 1.
expnw- another exponent wave with period of 1.
moogw- moog wave with period of 1.
moogsaww- moog-saw wave with period of 1.
you can use * % ^ / + - pow sin log pi etc.
* Xpressive Plug-In:
Added Release transition knob that control the "rel" variable. (the
duration of transit from 0 to 1)
Fixed some problems in the displays. (update display when changing
A1,A2,A3, clear display with invalid expression.
* X-Pressive Plug-In: Few more fixes
Changed the callbacks in exprfront.cpp to be templated.
Added help.
Added ExprTk.hpp.
some bug fixes (inf issues).
Added integrate function.
* Special version of ExprTk with modified license (BSL) for the LMMS project https://github.com/LMMS/lmms
* Xpressive Plug-In- fixed some building errors.
Added the "e" euler's constant.
* Xpressive Plug-In - fix mingw64 issues
* X-Pressive Plug-in:
Added "trel" (time since release) variable.
The integrate function can now have unlimited usage.
Added selective interpolation per wave.
Improved a little the random vector function.
Some other improvements, code cleaning, etc...
* Xpressive Plug-In:
move clearGraph definition into Graph.cpp.
fixed compilation errors. (oops..)
* X-Pressive plug-in: updated presets names
* X-Pressive plug-in
added semitone function, added sample-rate variable
* X-Pressive plug-in, code cleaning, changed the rendering function to
achieve performace gain.

* X-Pressive plug-in - until somebody will find a better solution,
exprtk.hpp is patched under the name exprtk.patched.hpp ...
* X-Pressive plug-in - fix compiling errors.
* X-Pressive plug-in - added patch file for exprtk.hpp,
added last function that gives last calculated samples.
moved ExprSynth to be with ExprFront for performance reasons.
* X-Pressive plugin - moved the patched file back to the source tree, added .gitignore file..
* X-Pressive plugin - fix compilation error. (isnan isinf)

* Updates to ExprTk
* Added return statement enable/disable via parser settings
Added exprtk_disable_return_statement macro for disabling return statements and associated exceptions at the source code level.
* X-Pressive plugin - updated CMakeLists.txt to use the correct flags on each platform.
also added exprtk.hpp as a dependency for the patch command.
Updated the exprtk diff file.
* X-Pressive plugin - moved the enhanced features flag to the WIN64 installation.
* X-Pressive plugin - another fix for CMakeLists.txt
* Minor updates to ExprTk
Updated multi-sub expression operator to return final sub-expression type.
Updates to exprtk_disable_return_statement macro for disabling return statements and associated exceptions at the source code level.
* X-Pressive plug-in - added try-block around exprtk calls and enabled the
-fexceptions flag, so patch file is no longer needed.
* X-Pressive plug-in - small fix in CMakeLists.txt
* Update ExprTk to tip of branch.
* X-Pressive plugin - added graph drawing feature..
* Updating exprtk.hpp to the latest upstream version
