MIDI INPUT NOT WORKING WHEN EDITING MISIC

This is what happens.
I write music with midi notes input… using a PreSonus AudioBox and a Yamaha Clavinova keyboard… While editing (changing) some notes I have previously written midi input does not work any more … Never happened with Dorico 2

A. There’s no need to shout.
B. If you search you’ll find similar threads such as here and here. It saves everyone’s time if you can join existing threads (about the same topic) rather than starting new ones.
