Dan's formula

Thanks, Dave Keenan, for your work on this thread. Dan's formula is very
interesting, and your charts are very handy. I had never noticed how
viable 37tET was a 7-limit...

You and Dan are both prime candidates for Scala. It will approximate any
scale with ratios, and you can restrict the ratios it returns by prime
limit and/or a number of other weighting schemes. Scala will also find ET
approximations to rational scales to an arbitrary degree of accuracy.
