A bit of piano braindance. Enjoy!

This is a good start for a piano track, but it could use some polish. A good idea would be to adjust the timing and velocity for every note. It helps it sound more like someone is actually playing it, no one is ever perfectly on time or plays the same volume every note. You could do it manually, but most DAW's have algorithms to do it for you. Hope that helps!
