I have a problem that i should know howto solve it is probably very basic.

Normally when you have choices, the most common way is to solve it with if, else if.

But sometimes your choices is fundamental to a process, so they are the input parmeters for something.

In my case i have a metronome, but depending on the "synth/hardware" you want to use you simply select it from an option list.

And now i could do 

if (met=="external") {something sent to port)
else if (met=="othersynth") {something else sent to port}
else if (met=="anothersynth") {something else sent to port}


If these are timed events it is not that effective to do this x times a second.

So you just want check and set the case once? and then be used everytime during the interval?

I guess that means to breakout the if cases into functions?
But you just want the actual function call to differ, but not be checked every time you send something to the metronome.

Basicly about setting what function to be called once, like flipping a switch and then it always take that "path".

I have a slight memory it could be case programming using switches, but i don't quite see hot it applies dealing with timed events during an interval?

Basicly i want to replace if else if before every metronome event.
