Is this the way Moog did it with osc. and filter drivers?

For other controllers then keyboards, like continuous sources the
exponential scaling is necessary, because higher notes would have
different resolution the lower.
Anyway, having the linear input fully featured (pots, manual, cv in)
is allways a good idea.

It is very difficult to say how the modules willl be used in the future,so better spend a little more time, money and panel area...
