OK tell us more about this. The execution is flawless, the shading and nuances wonderful!

Had to have been recorded in Carnegie Hall!

Wow!

Information.
It is one of the Demo Midi files on my Wersi Abacus with OAS 6 software, so it is unknown who the original Artist was that recorded the Midi File.
The performance would indicate that it was played on the Wersi Giga Piano, as this is the only OAS instrument that has a 88 note Weighted Hammer Action Keyboard, the Midi file would have been recorded using the Midi Record function.
The Piano sound in this case however, is the standard piano voice of my Wersi Abacus OAS 6, using a long reverb preset and the output EQ adjusted to give a balanced sound on a standard audio system.
I am glad you enjoyed it.
