you mean that midi note is 32 Hz, and then midi note 33 is just one BP step above that?
if your equivalence interval is "e"
and your divisions of that interval are "d"
then for some note "n," assuming note 0 is 32 Hz, the formula is 32*e^(n/d)
let's say that in fact, your base frequency for note 0 is "b" Hz
then it's b*e^(n/d)
