The acoustic piano is very warm and well mixed. I couldnt hear the background noise.
Well, this was on the keyboard, recorded line in, so there was no background noise, but if you check out my song "Am I still Alive?" You can distinctly hear the buzzing. Still, I happen to like the fuller sound of a live piano over a keyboard.
Please contact me if you would like to use this in a project. We can discuss the details.
