Hidden Electro-Acoustic Piano

1959 by Sampleson is based on the electro-acoustic piano patent registered in 1959. Sampleson brought it to life using spectral modelling. It's sound can be described as CP80-like but a bit more tuned due to the fewer number of strings.

The Experience of Recreating a Forgotten Electro-Acoustic Piano Patent

Does it sound like the original one? Sampleson don't know, because it has never been built. And they won't build it (for the moment). But the experience of bringing to life an instrument that never existed, was super-exciting.

The resulting sound of this virtual instrument is warm, clean and bright. The expressiveness of the piano action Sampleson emulated gives it a nice and wide range of timbres. From warm lows to metallic shines on higher velocities.
