[Impromptu] smooth value changes

[Si Mills]

Hi

I seem to be working my way through all the audio programming languages in the known universe :)....I'd heard of Impromptu, but never really got around to checking it til now. I'm honestly a bit gob-smaked at how much power you are able to lever from the core audio/ audio unit system! I had no idea that this was possible, but its all clear and makes perfect sense. Having the option of using ready rolled instruments and effects will make creative ideas flow a lot more quickly. A lot to learn first.....anyhow I digress

I was running a call back loop and changing the parameter of the automat synth randomly. Then it occurred to me whether there was a function to smooth or lag the parameter jumps, sort off like a low pass filter to smooth the transitions.

Then to that end, hows does one achieve portamento effects on say the frequency fed to the basic oscillator?

many thanks
Si
