Nice and simple rackspace for a layered sound of Piano and Strings.
The piano sound is used from the cool “Keys of the 70’s” plugin (supplied in Gig Perfomer 4) and the strings sound comes from the free amazing synthesizer plugin “The Surge”.

You can adjust the levels of those two sounds separately to your taste, as well as the reverb settings of the piano. The whole output can be adjusted (or muted) by using an extra Fader.
Have fun with it!
