Question (or Task)

How do I create a 72-step equal tempered microtonal tuning scale?

Solution(s)

For a 72-step equal tempered microtonal scale based on a tonic of C, you can use the following expression in the Frequency field of your Sound:

!KeyPitch - 60 nn * 12 / 72 + 60 nn

This takes the pitch from the keyboard, normalizes it to (0,11), then scales the size of an octave to (12/72), then adds this scaled pitch offset back to the tonic. The nice thing about doing it this way is that you could have hot values for the tonic and for the number of steps per octave!

!KeyPitch - !Tonic nn * 12 / !Steps + !Tonic nn

In the VCS, scale !Tonic to have a range from (60,71) and !Steps to have a range of whatever you want, for example (12,72) with a grid of 1.
