Audio taper calculations

[rohitmohan96]

I've been using your excellent documentation of the protocol to develop my implementation of the Fender app for the web (using WebHID). It's been incredibly helpful!

As I was working on the various DSP unit parameters, I noticed that while the amp reports values in different ranges (like 0 to 1, -60 to 0, -40 to -7, etc.), the controls on the amp itself are always from 1 to 10 (in increments of 0.1, I believe?). I also observed that the pots aren't always linear and sometimes follow a logarithmic scale.

I was curious if you’ve figured out how to convert between these different values?

Additionally, I came across the dsp_units.json file in your code, which seems to describe the various knobs in detail. Did you manually create this file? I noticed the taper values might be relevant to my question, but I'm not entirely sure how to utilize them.

I took a look through your code but wasn’t quite able to find an implementation related to this. Any guidance you could provide would be greatly appreciated!

Thanks so much in advance!
