propagating undefined values — or other potential errors,
like exceptions reaching Mixxx, or whatever.

mixco.transform table are often found by these, among
other trivial problems in the user scripts.
We simulate here that we send values to all controls
that are script mapped. We run through the controls in
different orders, increasing the likelihood of executing
behaviours that lie under modifiers. Note the check
ev.value == value after creating the event — this way
we prevent sending the note off message of some
buttons when we do not intend to.
