Control pitch instability in Zebra

[Hanz Meyzer]

Hi,

sometimes the pitch instability seems to be a bit too much, esp. in sum with a lot of Zebra sounds. Which settings are responsible here? There is pitch drift, but it only is a binary switch. I would like to control the amount of instability with a knob. For a glassy pad, I think it might be better to don't have any instability.

Is it possible to have it also perfectly stable?

Or make the instability go away only on bass notes? So some specific control of it?
