Ideally what I'd like is a traditional keyboard portamento, with the ability to set it to Legato only or all notes and if possible selectable between constant time and constant pitch. Mono and poly versions.

Can anyone assist or point me to an example in the sound library I might have missed?

Cheers
Sean

This is a great mono implementation of the sort of thing I'm looking for but wow, I didn't think it would be this complicated.

For mono just add Smooth: !Porta s on the end of the formula that is controlling the frequency.
You may need to put the rest of the formula in brackets first, or you may need to do it with the hz outside outside as below

((YourPitchFormular) smooth: !porta s) hz

all depends where you are using it.

Poly portamento is really as tricky as Robs sound suggests. This is because the note priority in kyma ( and most newer synths) lends it's self to sample players where voices are cyclically
selected. This means that if you had 8 note poly you would have to play a ninth note before note 1 would have a target to portamento to.

Only the very first Poly synths had selectable note allocation but it proved to be so complicated for the user and cause note stealing when you wasn't expecting it, that it was just dropped. I don't know of any modern day synths that have true Poly portamento but maybe others know different.
