Giovanni, I am using a laptop Computer that is 8 years old. I use it for all my midi files, music notation and chords and words. I am also using it to play my CD’s.

My laptop is plugged directly into the line impute of my KN7000 giving me control of the volume. It also can project what is the laptop screen (lyrics and notation) on to a TV screen..
Bernie has added a unit to improve the audio sound coming from the laptop.

Just my thought, John C.
