Create/Edit instrument defining the possible harmonic combinations
Is there any way to define in the instruments.xml (either when creating or editing an instrument) the harmonic combinations that are actually possible for a given instrument?
Example: the harmonica is a "harmonic" instrument, it can play more than one note at a time, but there is just an exact amount of possible double/triple notes. That means that certain combinations of notes are physically incorrect.
I would like to be able to define that on the xml instrument definition, so the note combinations that are not possible are marked in red or any sort of mark.
