SubVI Not Looping - Simple Universal Instrument Tuner


Recommended Posts


I'm using the subVI "String Selector.vi" to select the frequency I need to tune to. The "Instrument Tuner.vi" determines whether or not the instrument's frequency is sharp, flat, or in tune. When I run "string selector.vi" independently (in a while loop or running continuously), the output / "desired fundamental frequency" updates quickly and correctly. However, now that I am using it within the Instrument tuner VI, it does not update.

My goal is to get the "Desired Fundamental Frequency" to update if i click on a different instrument / string the same way it does when I click octave1, octave2, or octave3. Any ideas as to how i can get the desired fundamental frequency to update correctly?

Well the string selectors listboxes of instrument tuner.vi (Cello Strings, Guitar Strings, and so on) are not related to the ones inside String Selector.vi at all... You need a way to pass their values to String Selector.vi otherwise String Selector.vi will keep using their default value (index 0).
