Automation

[cmbourget]

Hello,


I have non-HD Pro tools.



I'm looking for how to automate the expression in real time (with my expression pedal) over already written notes and without erasing those notes.


So, 1) I record notes. But 2) I want to modify in real time the expression (11). If I try, I see the expression line change, but with the erasure (or replacement) of existing notes.

There must be a function to modify the controller data by keeping the notes.
