Need expressive, dynamic, Hypersampled pianos that fit your production? Pianos so good they can actually measure up to the real thing? We think you do.Reason Pianos is the perfect piano package: three stunning sounding, highly realistic pianos for Reason’s Combinator. Reason Pianos were recorded from multiple angles, using six different sets of microphones. Why? Because there’s no one way to record a piano.
