We are aware that many people have found an “Easter Egg” acoustic piano Voice in their reface CP.
Some background:This particular Voice is something we use for internal testing. We use this Voice because it takes up very little space and provides an easy way for us to test various aspects of our instruments. This Voice is purely for internal testing and is not reflective of our desire to bring you incredibly high-quality, expressive instrument Voices that are perfectly matched to both the keyboard and effects.
However, if this Voice works for you as-is - and you can find a way to easily re-create - there’s no harm to your reface CP in using it. Apologies for our delay in responding.
