Re: Composing My Own Music

I once had a program titled "Music Transcription System II by Questar Products Ltd" which allowed me to play by ear any song on the computer keyboard. It showed the staff and notes as I played them. I could also changed the note and the timing as well as being able to print it out. This program will no longer work on my updated computer and I certainly would like another program with the same capabilities.
When I hear a song I want to remember so that I can play it by ear, I used to play it on my computer keyboard and then print it out. I play for different organizations and would like to know if there is a similar program available.
