I’m also having this problem checking the box suggested in midi options did not solve it. Like the OP, I notice this is only happening when retrospective record is triggered inside the loop region.
Does anyone have any solutions / ideas why? Quite annoying to have such a handy feature no longer work.
Hyper, what midi controller do you have? I discovered that this weird behaviour doesnt work with Novation Remote SL but it is there when i use Axiom 49… AND i still have it even with option checked. Record works well but retrospective record gives wrong notes length… i suppose that somehow NOTE OFF messages are ommited.
