## maths for noise added to frequency for analog modeling

Jul 14 2017 | 6:48 pm

I'm trying to find the proper maths to add bits of noise to the frequency of an analog modeling type synth. Namely so when I add this noise to the freq (say between -.1 and +.1) it changes the pitch of the synth the same amount whether the frequency is 55 or 440. I think I need to use logarithmic scaling or something but not positive on how this would work exactly
