I like the general direction you are going. I wonder if it cannot be a bit
more simple in that you could define the number of steps in a key/mode by
simply the number of define frequency blocks in the clamp? and maybe you
don't need to modify the pitch block to return an argument? It could just
be a hertz block contained in the define frequency clamp. (Maybe the block
should be define step?) I am assuming that the widget would output a stack
of code like this? And to activate it, it would simply be run before
everything else? There is a mechanism for saving stacks to be used between
projects, so I could imaging making a temperament you like and reusing it
again and again.

I need to add an export button for the block artwork. I typically just use
