To make my poly synth less sterile, I'd like to simulate small oscillator drift, as a value to be added to the note input of my oscillator.
What I need for that (I think) is smoothly interpolated noise within a specified range (f.e. [-0.1, 0.1]), and be able to specify the max speed at which it is allowed to change (to prevent sudden jumps/drops).
Can anybody point me in the right direction on how to go about that?
(Or if you have other suggestions for smooth, limited oscillator drift I'd love to hear that as well ofcourse)
