Hello,
I am a professional musician for over 15 years now, and with over 7 years of experience in various music programs (one of them is Cubase 5), as a composer, music producer, audio engineer, etc., with songs and projects from all kind of genres.
Since i work with a keyboard as well, I could introduce you to the program, and everything else that you need.
If you have any questions, please feel free to contact me!
Kind regards.
