First of all, I think the ability to select all notes in a tie chain is a great feature! However: there are many instances where I might want to split up a tie chain (i.e. a pedal note I want to rearticulate halfway through an 8 bar sustain.) Is this feature on the to-do list? The current method of having to re-input the notes from the beginning is already becoming very tedious.
there is a feature for that on the to-do list, yes. Hopefully for one of the upcoming patch releases.
