Option to choose between audio and linear taper when using expression pedals!  
Or even more tweakable for example let the user draw the actual taper of the exp pedal as a graph.  
Right now it goes up too fast in the first half of the pedal (from heel down positon )  
Not so natural sounding as a volume pedal.  
I am using Lehle dual expression ( tried both 10k,50k but same taper)

Adding a transfer function tool to allow us to map our own curves in exp input would be very empowering.
