this is what i meant when i said: a is fixed by the max-value, as soon as b (shape) is chosen ...if i'm not mistaken
as said, i would adjust b in a way such that the graph passes though x = 0.5, y = "some middle value", perhaps 1kHz if we are dealing with...
...maybe i could come up with an equation to automatically calculate b from such a requirement....but i think, it involves solving an implicit equation
...could certainly be done by newton iteration, though
what about tanh?
for what kind of parameter is this?
what was your rational shape formula - do you know this off the cuff? ...the one with a and x or x^2 in numerator and denominator. this came up before...
yes. i guess, it makes sense to provide a mapper using these curves, too. maybe in two versions: unipolar and bipolar

aha! good to know. so it needs some fine tuning of the parameter mapping to make it feel more "musical"
