hmmmm, not recommended.

you can exponentiate electronically, but these circuits are finicky and the pots are probably not true log curves, so you would wind up with nonlinear response anyway.

you can use a look up table but you lose resolution (and more at one end than the other)

and you would need to fine tune the table for each pot to come close to linear...

otoh, those would be great for an analog audio device

I agree with the others that it would make more sense to use them in an analogue circuit, but I came across an old article describing how to change the characteristics of log & linear pots which may be of interest if you're determined to try to use the faders. http://www.elby-designs.com/documents/tailoringpotentionometers.pdf - but, as the article mentions, you're only going to get a rough approximation of a linear characteristics, even if your faders turn out to have ideal log characteristics. Might be worth investigating anyway...
