Pure data Conversion v/oct to frequency

does anyone know how to do a v_oct / frequency conversion in pd ??? I did the FM Perc patch and I implemented the midi usb, but I would also like to have the possibility to enter with a v / oct in the left input. Can someone help me?? I saw that with max you can do it. Thanks

hey cool!

You will have to add an offset and multiply by a scalar to get the voltage of a sample on an audio input.
And then convert voltage to frequency with e.g. 220*pow(2, voltage)
There’s a Pd example here:

You might have to adjust the offset and scale values to get perfect tracking.
