Make data events editable for multiple notes in Piano Roll Editor
Currently, there is no way of resetting event data (e.g., velocity and ontime) of multiple notes to default (e.g., zero offset without manually dragging the levels in the Levels Display Area back into place. If more than one note is selected, the data event setting boxes in the upper part, below the transport controls, become unavailable, preventing one from changing the velocity and ontime values back to zero, for example. While the velocity can be reset to default in the main notation view of the app with the Inspector, ontime and length data can't.
I suggest making the data event settings in the upper part of the PRE available for multiple notes and adding a keyboard shortcut to be able to select all the notes, as in the main app--ctrl + a.
