Is Cubasis 3 more stable than Cubasis 2 re: routing?

I’m using Cubasis 2 and I’ve been audio-routing synth apps (Zeeon) from AUM to Cubasis so I can record it as audio directly onto a track. It works perfectly, but I get so pissed off because after about 10mins, it crashes out and I have to either go back and rewire the whole thing, or force quit AUM and load it all up again.

Same thing happens with Ape Matrix.

Is Cubasis 3 worth a purchase in this regard? Is it more stable?

Hi all, I’d love some opinion on this if possible. I’d gladly upgrade if I knew it would solve this error.
