I have a patch that adjust the frequency of a [biquad~] via a filtergraph. I want to be able to adjust the frequency using a [dial] as well as a [flonum], and have the [dial] update the [flonum] and vice versa. The problem I have is that because I'm using a [linedrive] to add a curve to the output of the [dial], when I adjust the [flonum] the needle on the dial jumps.
I can't figure out how to reverse the curve of the [linedrive] so that the [flonum] lines up with the [dial]. Does anyone have any suggestions?
