I have a very simple sigmund patch.

As [adc~]---[sigmund~ pitch]---[number].

For example, with this patch number is 71.2 for 500hz external noise.
How can i convert this 71.2 pitch value to frequency. What is this 71.2 value?

thanks

71.2 is the midi number of the corresponding frequencies (wrong terminology?). You can convert with the "midi to frequency" object:

[71.2\
l
[mtof]
l
[499.6\
