Sending Hertz per Volt sequences from Pd

Hi all!

I am using my Organelle M to send MIDI to my modular synth, via a MIDI to CV converter.
Using Pd’s standard makenote and noteout objects, it’s simple enough to get v/oct sequences into the modular.

I recently bought a module which takes pitch CV as Hertz per Volt, which behaves pretty differently
I think it has something to do with the pitch information being exponential rather than linear…?
Does anyone know of an easy way to convert MIDI/frequency information to Hz/volt in Pd?

Cheers

What module is that? “Hz/volt” implies it’s linear.
