If you look at the timing parameters for the default legato in the Play Options timing page, it shows 105% of duration. This should overlap notes in the play mode view of the actual note duration. But it looks like it is applying 105% to the 85% default note duration, so you still don’t get overlap for legato unless you increase the default normal note duration timing to say 95%.
Is this the intended effect?
This seems to be different from previous version, but I could be wrong about that. But I don’t remember running into this issue before.
