/** Dialog for building a MIDI note transformation.
|
|
*
|
|
* This can build transformations with any number of operations, but is limited
|
|
* in power and can't build arbitrary transformations since there is no way to do
|
|
* conceptually parenthetical things (i.e. push things to the stack).
|
|
*
|
|
* With this, it is possible to build transformations that process a single
|
|
* value in a series of steps starting with a seed, like: "value = seed OP
|
|
* value OP value ..." where OP is +, -, *, or /, left associative with no
|
|
* precedence. This is simple and pretty clear to the user what's going to
|
|
* happen, though a bit limited. It would be nice if the GUI could build
|
|
* fancier transformations, but it's not obvious how to do this without making
|
|
* things more confusing.
