2) Partly more in the design of orchestral instruments: I would like to know, what's the best way to *smoothly* model an increase in instrument attack (resulting, usually, in increasing loudness/brightness)...so at whatever resolution for the above control I pick, my instruments go from nothing to LOUD with a perception of a "straight-line"...I know this involves the ear's tending to follow a Decibel curve, but I also know this changes with pitch, too. But assuming pitch isn't an issue because that will change anyway, what's the best approach in instrument control design to give a composer using microcsound a good sense that "this will be pianissimo" or "this will be mezzo-forte", or "this will be fortissimo!!!"???

Thanks,
