I can't advise on what's the "right" way to do this, but two suggestions: Try it and see if non-linear portamento sounds any different (or any better) than linear. Consider a physical model. I'd have thought that the movements a musician makes as s/he slides from one note to another would probably be /fairly/ linear, and that the resulting frequencies would be non-linear only because the relation between "position" (whatever that means in context) and frequency would be non-linear. Of course my assumptions may be wrong (I'm no musician), but my point is to consider /some/ physical model as guide to what's "right". -- chris
