I think it works by tracks, not clip, so we lose the position. But I will deepen with Cubase 10 and Wl 10.
No Aes-31 in Pro Tools, indeed. It’s an old format, basically, replaced by OMF and then AAF. It is however Nuendo. Conclusion: Steinberg, do you want a transfer method between Cubase and WL, or just for Nuendo and WL?
