I cancelled this post as I have solved my problem by reading the Tutorial

Can you help me solve the following problem:

• I connected my electric piano to a laptop via a USB port.
• I checked that the connections work with the help of the following website: https://hardwaretester.com/midi
• I would like to do one of the following two things: 1) or 2)
  1) In INPUT: Play the piano
  In OUTPUT: create a MIDI FILE that will include what I played on the piano
  2) In INPUT: open MIDI FILE
  b OUTPUT: that the piano will play the MIDI FILE
• I learned that MuseScore 4 can do this
• But when I am in Input Notes and I play the piano, the notes are not entered to the score which is open in MuseScore 4.

Thanks in advance for your help,
Yossi
