it’s possible to linearize some of the analog inputs via software to attach some log pots?
You could map the analog value to a new value, similar to the way how it is done in analog_toolbox. But in general the results won’t be good enough for serious work, because you will miss some values!

i have to try… if it will offer sufficent precision i’ll be very happy
if not i have to try in analog way 
???
Selfservice,
I think the hardware idea has come up here before, and the consensus was that it can only work the other way around (lin to log) with resistors. 
Maybe TK or someone would know if you could get a more “software cooperative” version of an audio log pot by adding something. (?)
