Metropolis + Little Phatty

Hi, I want to control my Little phatty by the Metropolis using CV
The thing is, pitch CV-in on the little Phatty is not really 1 V/oct but rather 0.97 V/Oct.

What is the easiest or best way to deal with this ? I think I have to use an attenuator between the Metropolis and the Little Phatty ? Like the Erica SYnths Pico Attenuator ? or the doepfer a-183-2 ?

thanks for replying

You can use any attenuator, triatt or quadratt would work too.
