Native Instruments has again provided the producers of the world with a new virtual unique piano: UNA CORDA. It is based on a 64-key upright piano. It mentions that unlike standard pianos, who use more than one string per key, this piano is unusual in that it has just one string per key. There are other features in this special built pianos that makes it truly unique, like the location where it was sampled and recorded to the materials that affect the sound of this instrument, but it can be read on the official press release.
