We have an entire mechanism to deal with exactly that case: Prameter
Pre-Processors.
Often not even that will be neccesary. The common case (IME) is that you
have a slider whos position is non-linear with the value it sends to the
parameter (eg gain in dB's), but that mapping is done by the UI, the
spinbutton or text control is still expressed in dB's as thats the natural
unit of the control.
