squared pitchbend line from keyboard

Hello all,

When pitchbending from my keyboard knob (Prodipe 49C), I get like an unprogressive line in the edition window, resulting in an unprogressive changing sound (left image). Of course, I can work the line in the edition (right image), but I’d like to know what I can configure to get at first a full progressive shape. This does not happen under GarageBand, this is why I think the issue comes from Cubase.

I thank you in advance for any advice :slight_smile:
