first I say thanks for giving the module away for free. It's indeed useful for various purposes.
For example, I chained several Ratios to amplify a signal by a large factor. Good, that "voltages" in VM are only numbers and cannot damage any module.
BTW: I find module description in CA store is a bit confusing.
I would not say, in EXP mode it's the same because there is not multiplication. Instead there is a constant value added to the input signal which depends on preset NUMERATOR and DENUMERATOR.In "linear" mode, Ratios multiplies an inbound CV signal by a whole number between 1 and 20 inclusive, then divides it by a whole number between 1 and 20 inclusive, sending the result to the output jack. In "exponential" mode, it does the same thing but on the log2 exponential scale used by frequency controls.
