super smooth oscillators

Hi. What I am trying to do is get a oscillator that is sweepable by hand (through the Max/MSP interface, perhaps MIDI later) that doesn’t zipper through discreet values or have too many artifacts (we’ll be glissing pretty slow mostly) and is as silky smooth and clean as possible when glissando(ing).

So far, fail. haha. I am open to fixes or just a total rethink of the whole thing. I also tried to use the expr(expr (pow(blahblahblah)) * 440.) trick to get a sweep that is more perceptually even (ballpark) on the slider.

Essentially I want a super clean sine sweep that is like an test oscillator with a nice super smooth dial on it.

Any help, fixes, tips, enlightenment would be appreciated…

Is this better?

That one little addition is already an enormous improvement. I should have remembered about rampsmooth~ brilliant. Thank you.
